Technical Field

The invention relates to a packaging, in particular a sterile packaging, for a medical-technical tool, comprising a receiving space for the medical-technical tool. The invention also relates to a method for automatically identifying a medical technical tool by means of a package.

Background

Many different packages and devices for medical-technical products, in particular tools, are known. Packaging (for example in the form of cutting or sawing edges, milling heads and drills or threaded parts) of medical-technical products (for example implants and tools) with sharp tips and/or sharp active parts is required to meet specific requirements. In addition to the need to protect the user from injury before and especially after use of the product, the packaged product must also be protected from undesirable effects, such as contamination and damage.

Another requirement for packaging is that it be capable of properly identifying the product packaged therein, which is especially important if the packaged product itself is not visible (e.g., due to being covered by the packaging) or the product is not discernible and/or identifiable (e.g., certain identifying features such as materials, dimensions, etc. are not readily visible from the product). Reliable and unambiguous identification of a medical-technical product, such as a surgical instrument, a surgical tool or an implant) is of great importance in terms of patient safety.

Another important aspect of medical technology tools may be the transmission and communication of tool specific information. This may be, for example, as to whether a certain tool is appropriate for a certain application and/or the condition of the tool. For example, it is often important for a medical technology tool whether it is used, frequency of use, life time, and inventory. Such information is often difficult or impossible to communicate and maintain using conventional packaging.

The prior art is to identify the packaged tool by means of a user-identifiable tag attached to or in the package. This is disadvantageous in that the user cannot easily and positively identify the tool in the package if the user does not perform a separate and careful inspection of the label and/or the package. In addition, for such labels, additional information (e.g., maximum usable size, materials, etc.) may be difficult to present, must be carefully recorded by the provider, and may be difficult for the user to obtain due to, for example, contamination or wear. Furthermore, the handling of sterile products (e.g., surgical instruments and tools), in particular, may be limited (e.g., time pressure or pressure during surgery) when the sterile products are removed from the packaging, which may make it difficult for a user to obtain and/or record product-specific data. This is particularly critical, since misuse of medical tools, due to insufficient access to the respective tool and its properties or use properties, can quickly lead to serious negative consequences, particularly for the patient. Finally, known packages do not provide or only provide limited possibilities for written tool identification.

Packages are known in the prior art which fix medical tools in their packages in a fixed and/or position-defined manner. An example of one such package is a blister pack with a clamp in the coupling region of the tool to position and secure it in a defined position in the pack. Such a package is disclosed, for example, in DE 102013004168 a1, in which the surgical tools are packaged under sterile conditions in a plastic package which is divided into at least two parts and consists of an inner protective package for the sensitive parts of the surgical tools and a sealable blister pack containing the protective package. Furthermore, a method for packaging sterile surgical tools is proposed, in which the surgical tools are packaged under sterile conditions in a plastic packaging, in a first step the surgical tools, at least in part, in particular the sensitive cutting edges and the active surfaces thereof, are first packaged in a first protective packaging, and the protective packaging together with the surgical tools packaged therein is placed in a second blister packaging, fixed there in a positionally fixed manner and then sealed with a sealing film. A disadvantage of this package is that although it protects the active edge of the tool well, the tool itself cannot be identified by the package or is difficult for the user to identify.

Disclosure of Invention

Against this background, the object of the present invention is to reduce the above-mentioned disadvantages of the prior art, in particular to provide a packaging for medical-technical tools or a tool support arranged therein, by means of which the individually packaged tools can be easily and reliably identified and the risk of incorrect use of the tools can be minimized.

The object of the invention is achieved by a packaging/support for a medical-technical tool, in particular a sterile packaging, with a receiving space for a medical-technical tool, according to claim 1, wherein the packaging or the support located in the packaging comprises a readable data carrier with tool-specific data. The above task is also achieved by a method for automatically identifying a medical technical tool by means of a package or a support in such a package according to the present invention, in particular according to any claim, comprising the following steps:

-the supplier placing the tool into the containment space of the package;

-the provider writing tool-specific data to the data carrier;

-the user opens the package;

-the user identifies the tool by reading the data carrier.

A tool in the sense of the present invention is to be understood in particular as a surgical tool having a generally distal, sharp effective portion for performing an operating function and a proximal coupling portion for coupling the tool to a handle unit, in particular a drive handle unit. Examples of such tools are, inter alia, rotary tools and sawing tools, including drills, mills, saws, screw attachments, cutting blades or grinding attachments, which are connected to the handle and/or the drive unit in a manner known per se. Furthermore, a tool in the sense of the present invention is also understood to be a nozzle, an HF injector, an ultrasonic blade, etc. Finally, the term "tool" in the sense of the present invention also includes implants of any type and shape, such as bone and joint implants or partial implants, stents, etc.

A particular advantage of the present invention is that the tool can be automatically identified when the user removes it from the package. The data carrier is designed to communicate preferably wirelessly with an external reading and/or writing unit. It is particularly advantageous if the tool is used with a handle with a reading device by means of which the data contained in the data carrier can be recognized and/or read, since then the tool can be recognized when connected/arranged/inserted into the handle. The data acquired in this way can be transmitted/displayed to the user on a display unit communicating with the handle.

Data written to the data carrier in the sense of the present invention can be an item number, a batch number, a latest date of use, a validity or maximum date of use, materials, dimensions and geometry, use, previous use and age, stock, etc.

The basic idea of the invention consists in performing tool recognition and transfer to the peripheral device by data transfer and displaying the selected data to the end user. While more data can be recorded and further processed.

Advantageous embodiments of the invention are claimed in the dependent claims and are explained in more detail below.

An embodiment of the invention is characterized in that the package comprises an outer package. In addition, the package may further comprise a holding device/tool support located in the receiving space. Such a clamping device can be advantageously arranged and/or fixed in a defined position in the receiving space. It is particularly suitable for fixing, in particular positionally fixing, the tool and for placing the tool in the receiving space in such a way that the sharp active portion is prevented from coming into contact with the packaging material and is isolated from the packaging. By providing such a clamping means, contact of the tool with the package portion may be prevented or at least reliably minimized. The holding device and/or the outer package may be composed at least partially, preferably entirely, of an absorbable material. The receiving space can be formed by an overwrapping closure, in particular a hermetic seal, and it can also be sterile. A particular advantage of the invention is that the data carrier can be read without the packaging being opened and without the sterility having to be abandoned.

According to one embodiment of the invention the holding device is designed to be separated from the outer package. The tool in the holding device can thus be removed together with the holding device from the outer package and can in particular also remain in the holding device after opening of the package until the end use. Preferably, the packaging and gripping means are designed such that the removal is achieved by handling the gripping means without direct contact with the tool, which simply and reliably minimizes, if not avoids, the possibility of contamination of the tool. Furthermore, the tool can be placed together with the holding device on a table without having to release the tool. The holding device can be used in a particularly advantageous manner for temporarily storing the tools during surgery or treatment, so that better order and clarity are obtained. The invention thus makes it possible, in addition to the packaging in the sense of practice, to provide independent storage by means of separate holding devices, which makes it possible to specifically locate and safely handle the tools, in addition to the tools stored safely and stably in the respective outer packaging during transport, as part of the preparation (e.g. sterilization) and when the products are supplied during the surgical treatment. Furthermore, the holding device can be removed from the outer package and placed together with the tool stored therein.

According to an embodiment of the invention, the data carrier may be an RFID tag or an NFC tag. It is particularly advantageous that its data can be read, written and processed contactlessly and automatically, in particular without any particular interaction with the user. The data carrier may in particular be permanently readable. It can in particular be arranged on the outer package or on the holding device. The data carrier can be arranged not only on the outer package but also on the holding device. The data carrier may in particular be glued on.

According to one embodiment of the invention, the data carrier and the outer package, or the data carrier and the holding means, are fixedly or inseparably connected to one another. The data carriers are therefore preferably glued, cast or pressed together. Hereby, accidental detachment of the data carrier and accidental separation of the data carrier from the packaging/holding means is excluded, which more reliably ensures that the data in the data carrier indeed belongs to the means located in the packaging/holding means. This advantageously increases the safety of the patient.

According to another embodiment of the invention, the data carrier can be activated. The activation of the data carrier can be achieved in particular by the relative positioning of the tool with respect to the packaging or the outer packaging or the holding device. For example, an antenna circuit and/or a current circuit and/or a switching circuit connected to the data carrier can be closed/activated by such a relative positioning, whereby the data carrier can be activated and read. This may be achieved by maintaining the current circuit antenna circuit and/or switching circuit in an open state when the tool is placed in the package in the intended manner so that it is in an inactive state, for example because the tool itself is insulated and interrupts the circuit, or because the tool deforms the package/overwrap/clamping device so as to cause the circuit to be interrupted. According to the method, the data carrier is activated by the relative positioning of the products in the receiving space or the holding device, or by removing the tool from the receiving space or the holding device (7, 26) to read or transmit data on the data carrier.

The antenna circuit and/or the current circuit may be part of the package. In particular, it can be integrated into or provided or designed on the outer package and/or the holding device. Preferably, the circuit is designed such that it remains in an open, i.e. inactive, state when the tool is placed in the package in the intended manner, and is closed or in a closed, i.e. active, state when the tool is removed from the intended position. This has the advantage that the data carrier is only read when the tool is removed from the packaging, which avoids or reduces unnecessary data traffic and energy consumption. With the method according to the invention, the data carrier can be read by a reading device preferably located in the handle when the tool located in the package, in particular the tool located in the holding device, is placed in a handle for holding the tool.

According to the inventive method, the tool can be placed in the receiving space or arranged in the holding device, and the data carrier can be written, preferably under sterile conditions, before or after the tool is placed in the receiving space or arranged in the holding device. This provides great flexibility. According to one embodiment of the method according to the invention it is provided that the gamma sterilization is performed after closing the package. Sterility can thereby be achieved without compromising the security function of the data carrier. The writing of the data carrier can also be performed after the sterilization according to an embodiment.

According to another embodiment of the invention it is particularly advantageous if the data read from the data carrier are displayed to a user of the tool. Alternatively or additionally, the data read out from the data carrier may be stored and/or forwarded to the provider of the tool. The above-described process is preferably automated, so that the data can be displayed and/or forwarded and/or stored in a database, in particular automatically.

The clamping means may comprise a base plate. This base plate can be designed in particular such that it forms a facade for the stable placement of the holding device in which the tool is stored, in particular in the state of removal from the packaging, and/or a mounting structure for mounting on the packaging. In addition to the elevation, the holding device may comprise further mounting structures or parts which can work together with the package and abut against the package to ensure a clear and stable position in the package receiving space. If the data carrier described within the scope of the invention is integrated into such a holding device or arranged thereon, it is made particularly easy to identify the tools stored in the holding device, for example on an instrument desk, during a medical procedure.

According to one embodiment of the invention, the gripping means may comprise at least two gripping structures spaced apart from each other for positioning the tool in a determined position. Preferably, the clamping structures are respectively provided on the bottom plate and may extend into the receiving space. In addition to the effect of gripping the tool, the gripping structure may also form a mounting by which the gripping device is placed against the package, preferably in a positionally determined manner in or fixed in the package. One of the clamping structures may be provided at the clamping device, in particular at the rearmost of the base plate. The other of said clamping structures may be provided substantially in the middle of said clamping means, in particular said base plate. This enables the tool to be held particularly stably in the holding device.

Preferably, one of the clamping structures for positionally fixed positioning of the tool is formed in a first direction relative to the clamping device. Other clamping structures for positionally fixed positioning of the tool are formed in a second direction and in a third direction relative to the clamping device, wherein the first, second and third directions are orthogonal to one another. By means of such a guidance, on the one hand the tool is held stably in the holding device, and on the other hand the tool can be placed in or removed from the holding device particularly easily by the user. It is particularly advantageous if, according to a further embodiment of the packaging, one of the clamping structures forms a form-fit and/or force-fit with the tool, in particular with a coupling structure of the tool.

At least one of the clamping structures, in particular both clamping structures, may comprise two clamping arms facing each other. A socket for receiving and securing the tool is formed between the holding arms. The clamp arm may be arranged substantially perpendicular to the base plate of the clamp device. They can be designed in a particularly advantageous manner as clamping arms and are particularly resilient in the direction transverse to the insertion slot. If according to one form of the invention the slot widens from the proximal end of the base end to the distal end of the base end, removal and placement of the tool is made very easy. This facilitates a largely risk-free handling of unused and also used instruments, thereby improving the damage-free handling of the tool in the setting and reducing the simultaneous risk of infection. According to a further development of the invention, the side of the clamping arm facing the socket is provided with an indentation. These indentations can advantageously form a locking recess for the insertion of a tool into the socket, so that this tool can be reliably secured in the clamping structure, but at the same time can be simply removed by the user.

An embodiment of the invention which is particularly user-friendly as it avoids injury to the user provides that the holding device comprises a protective strip which projects from the base plate into the receiving space and which covers a distal end of the tool or a sharp edge of the tool. In this way, the user is protected from possible sharp edges of the tool when operating the holding device in which the tool is placed.

According to one embodiment of the invention, the package is designed as a blister. Such a blister is inexpensive and can be produced as a product and/or a holding device of any shape. The blister pack may preferably have a lower housing with a recess forming said accommodation space for the tool. Such a recess is designed with sufficient stability and shape to provide stable positioning of the clamping device and the tool in its position. The receiving space can be closed in the most desired manner, in particular sealed and/or sterile, by a cover film which is arranged in a known manner on the recess. The data carrier may be placed on the lower case or the cover film.

According to another embodiment of the invention, the holding device may be coded, for example by painting it. In this way, the invention makes it possible to very easily provide a system by means of which different products can be coded in a manner that is easily distinguishable to the user, and such a code or marking for a specific tool is retained after the tool has been removed from the packaging, in each case in correspondence with the respective tool. In particular, the tool which has already been opened and is placed in the instrument desk or the disinfection device for use can be identified particularly easily and safely for the user. The identification of different tools and/or gripping devices can preferably be achieved by different coloring of the gripping devices, for example in view of their representation or a specific product group or the like. In this way, incorrect combinations of tools can be avoided by coloring the holding device, which is designed in particular as an injection-molded part, both inside and outside the packaging.

According to a further embodiment of the invention, the clamping device is designed as a plastic profile. If it is designed as a multi-component injection molding according to a further development of the invention, it is possible, for example, to provide a particularly slip-resistant base. This enables the holding device to be arranged stably on the instrument table and/or on a support element, such as a sieve basket, during preparation. Furthermore, this makes it possible to considerably improve the handling of the support device during the removal of undesired tools and during the introduction of desired tools. The data carrier may in particular be moulded/injected into the holding means.

A particular advantage of the invention is that the user can safely, easily, quickly and in particular automatically obtain information about a particular medical tool that he is using, or that he is intending to use, and/or that he is putting/is putting in a grip element without the need to look additionally at the label or the outer package. In particular, a user can automatically and easily identify whether the product being used is suitable for the application concerned. Another advantage of the present invention is that a user can easily and without having to make an inventory to know which inventory of tools involved are still in their warehouse (possibly a consignment warehouse).

The present invention provides significant advantages not only to the user but also to the provider of packaged medical products and tools: with the present invention, he can particularly easily determine which products/tools are combined and/or used. Furthermore, he can be aware of the overload of the tool and the possible product damage associated therewith. Finally, the invention can enable the provider to provide the appropriate customized logistics for the customer.

In summary, the invention makes it possible to identify, in particular automatically, the individual products to be used, in particular the individual tools to be inserted into the handle or the drive element. Furthermore, the invention enables any product-related data written on the data carrier to be maintained and transmitted particularly easily and largely fail-safe. The invention has the following advantages:

product identification, direct and automated for users and providers (supply chain management (SCM), services, error analysis);

to users and providers (supply chain management (SCM), services, error analysis)

Any number of additional data;

the invention offers the user the possibility to automatically and timely record product-related data into the patient case.

In other words, the present invention provides a tool holder or a tool holder adapted and arranged to be contained or formed in a sterile package to form an integral part of the package. The tool holder has at least one, preferably a plurality of (axially) spaced shank-receiving clips (each respectively consisting of two spring-elastic or spring-loaded clamping arms/jaws) which are located on, preferably integral with, a base or base plate, and preferably each respectively form one or more raised portions for (partially) containing a tool shank.

To avoid axial movement of the tool/tool shank, two (axially) spaced end stops may be formed or mounted on the shank-receiving clip on the base plate.

The readable data carrier (label) can in particular be placed on/in the base plate axially between the two end stops and preferably axially between the two grip receiving clips.

Detailed Description

Fig. 1 and 2 each show an embodiment of a package 1 according to the invention. The embodiment comprises an outer package 2 in the form of a blister 2 with a bottom shell 3 containing a recess 4 and a rim 5 surrounding the recess 4. The outer package 2 also comprises a cover film 6 which is arranged on the peripheral edge 5 of the bottom shell 3 and covers the recess 4 in a gas-tight manner, which is shown in fig. 1 and 3 in the partially open state. Both the bottom shell 3 and the cover film 6 may be composed of an absorbable material.

In the recess 4 of the outer package 2 of fig. 1 a holding device 7 is arranged in which a tool 8 as an example of a packaged product is fixed (see also fig. 3). The tool 8 is in this embodiment a drill bit 8, which at its distal end forms an active part 9 in the form of a drill bit and at its proximal end forms a coupling 10, the coupling 10 of which is intended for arranging the tool 8 on a tool receiving part of a drive handle unit, not shown. The tool 8 has an elongate tool shank 11 between the active portion 9 and the coupling formation 10.

According to the invention, a data carrier 42, here in the form of a data carrier readable and writable by radio, for example an NFC tag or an RFID tag 42, is arranged on the holding device 7 of the embodiment shown in fig. 1. In the embodiment of fig. 2, a data carrier 42, here also in the form of an RFID tag, is arranged on the outer package 2. Data specific to the tool 8 are stored on the data carrier 42 shown in fig. 1 and 2.

The clamping device 7 of the embodiment shown in fig. 1 is shown in fig. 3 without the outer package 2. It is formed as a plastic moulding, consisting entirely of absorbent material and having a base plate 12. A first clamp structure 13 is formed at the proximal end of the base plate 12. This first clamping structure 13 comprises two clamping arms 14, 15 which are parallel to each other and extend from the base plate 12 in a direction substantially perpendicular to the tools 8, respectively, and which are connected to the base plate 12. A socket 16 is formed between the clamping arms 14, 15 for receiving the coupling structure 10 of the tool 8. The base plate 12 is formed with a second clamp structure 17 in the middle, which extends from the base plate 12 in the same direction as the first clamp structure 13. The second holding structure 17 likewise has two holding arms 19, 20 which are opposite one another and between which a receiving slot 18 is formed, both holding arms 19, 20 being substantially perpendicular to the base plate 12. A third clamping structure 23 is formed between the first clamping structure 13 and the second clamping structure 17, and is substantially the same as the second clamping structure 17, and therefore, the description thereof is omitted. The data carrier 42 is arranged, here glued, on the side of the base plate 12 facing the tool 8.

Fig. 4 shows a holding device 7 similar to the holding device 7 shown in fig. 3 with a further tool 21, here a milling attachment, and a further data carrier 42, here in the form of a data carrier readable/writable by radio, for example an NFC tag or an RFID tag 42. The milling attachment 21, like the drill 8 shown in fig. 1 and 3, has a coupling structure 10 and a tool shank 11, and the milling attachment 21, unlike the drill 8, forms a milling head at its distal active portion 22. However, the drill bit 8 and the milling attachment 21 can be accommodated in the same holding device 7 by means of the invention. The data carrier 42 is again arranged on the base plate 12, but close to the coupling structure 10 of the milling attachment 21. The data carrier is connected to an antenna circuit 43. This antenna circuit has two contacts 44a and 44b which are electrically isolated from each other when the tool 21 is placed in the holding device as shown in fig. 4, so that the antenna circuit 43 is open. The antenna circuit may according to another embodiment be located at the bottom surface of the holding device 7. The circuit connections shown are intended to indicate that the antenna function is subsequently activated here. Likewise, the circuit connections may have other designs. For example, by a leaf spring or the like. The basic idea is that a circuit will close or open when the tool is removed.

The two contacts 44a and 44b are located in the region of the third clamping structure 23 in the embodiment shown in fig. 4. It is also contemplated that the contacts 44a and 44b may be disposed in different areas of the clamping device. For example, the contact 44a may be arranged/provided in the area of the third clamping structure 23, while the contact 44b is arranged/provided in the area of the first clamping structure 13. When the tool 21 is arranged in the holding device 7, the antenna circuit is preferably also closed in this case. When the contacts 44a and 44b are arranged in different areas of the holding device 7, unnecessary contact without tools can be better avoided.

Fig. 5 shows an enlarged detail of the second clamping structure 17 of the clamping device. The sides of the clamping arms 19, 20 facing each other are provided with two indentations 24, 25 of different sizes arranged one above the other for accommodating tool shanks 11 of different diameters (see also fig. 7, which shows a cross-sectional view of the second clamping structure 17 transverse to the longitudinal axis of the tools 8, 21). The gripping arms 19, 20 have some resilient spring properties and are spring movable relative to each other such that the socket 18 can be widened when the tool 8, 21 is placed in, and the gripping arms 19, 20 spring back to the initial position as soon as the shank 11 corresponding to the tool 8, 21 is placed in the indentation 24, 25. In this way, the tools 8, 21 can be securely fixed in the holding device 7. In particular between the clamping arms 19, 20. When the tool 8, 21 is positioned in the indentation, the clamping arms 19, 20 do not spring back completely back to their initial position, but are spaced apart from each other such that the contacts 44a, 44b of the antenna circuit 43 electrically connected to the data carrier are isolated from each other and the antenna circuit 43 is open. Only when the tool 8, 21 is removed from the slot 18 between the holding arms 19, 20 will the holding arms 19, 20 spring back again into their initial position, in which the contacts 44a, 44b come into contact with one another, so that after removal of the tool 8, 21 the antenna circuit 43 is closed and the data carrier 42 electrically connected thereto can be read.

A protective tape 38 is arranged at the end (effective portion side) of the base plate 12 opposite to the first clamp structure 13. The protective strip 38 projects first from the base plate 12 with an inclined portion with an angle of inclination, here about 45 deg., and then turns at another angle towards a terminal portion 40, so that the end facing away from the base plate 12 is substantially transverse to the base plate 12. As shown in particular in fig. 8, the protective strip 38 projects from the base plate 12 in such a manner that the respective distal ends of the active portions 9, 22 are covered without contact. The design of such a protective strip 38 provides a good grip by allowing the user to grip the inclined portion 39, for example from the position of an instrument desk as shown in fig. 6, in which the active portion is covered, thus reliably avoiding contact with it by the user, whereby the risk of injury is minimized. Fig. 8 also shows a radio readable/writable data carrier, such as an NFC tag or RFID tag 42, attached to the bottom side of the chassis 12.

Fig. 6 shows that the holding device 7 is adapted to receive and hold different tools 8, 21, provided that these tools all have a substantially similar basic shape, i.e. with a shank 11 and a proximally located coupling structure and differ only in respect of the respective active portions 9, 22. Fig. 6 shows by way of example a drill 8, a milling attachment 21, a screwing attachment 36 and a grinding attachment 37, wherein the shank diameter of the attachments 36, 37 is smaller than that of the attachments 8, 21, so that the attachments 36, 37 are arranged in the indentation 24 with the smaller diameter and the attachments 8, 21 are arranged in the indentation 25 with the larger diameter. Fig. 6 and 3 also show the suitability of the holding device 7 in addition to the positional fixing of the tools 8, 21 in the packaged state (the same applies to the holding device 26 described below), i.e. in the state shown in fig. 1 and 2, as a holding device which is usable independently of the outer package 2 for placing the tools, for example during surgical preparation or during sterilization. The bottom surface 41 of the base plate 12, 30 also forms a standing surface 41, so that the holding device 7, 26 with the tool fixed therein can be stably placed on the standing surface 41. Finally, fig. 6 shows that the contacts 44a and 44b of the antenna 43 are in contact with each other when no tool 8, 21 is present in the holding device 7. Fig. 5 shows a space that will be connected after the tool is removed.

In the recess 4 of the outer package 2 in fig. 2, a holding device is arranged in which a tool 27 is fixed. Said tool 27 is in the above described embodiment a saw attachment 27 formed at its distal end with an active part 28 in the form of a saw blade and at its proximal end with a coupling structure 29 for arranging said tool 27 in a tool receiving member of a not shown drive handle unit.

As shown in fig. 9 and 10, the holding device 26 has a base plate 30, to the top surface of which a data carrier, which can be in the form of an NFC tag or an RFID tag 42, for example, is connected via a radio-readable/writable data carrier as a data carrier with tool-specific data. Also on the base plate 30 are a first clamp structure 31 and a second clamp structure 32 spaced from each other in a direction transverse to the base plate 30. The clamping arrangement of fig. 9 and 10 is provided with a total of 3 sets of first and second clamping structures 31, 32 which can be used to accommodate different shapes and/or different sizes of saw attachments. The 3 different sets of clamping structures 31, 32 are substantially similar and therefore only one will be described below.

The first clamp structure has a spring arm 33 that is spring movable in a direction toward the base plate 30. The spring arm 33 is provided on its side facing away from the base plate 30 with a locking formation 34, here in the form of a locking projection 34, which is operable with the coupling formation 29 of the attachment 27 and is fixed in position relative to the second clamp formation 32 in a direction parallel to the base plate 30. The second clamp formation 32 is designed as a socket 35 through which the coupling formation of the saw attachment 27 can be pushed in until it is locked by the clamp formation 31 and the nose 34. The slot 35 is sized to enable the saw attachment 27 to be secured in position transverse to the base plate 30 and in the remaining direction parallel to the base plate 30. The slot 35 and the spring arm 33 are designed and positioned towards each other such that the saw attachment 27 can only be brought into a predetermined position with the spring arm 33 compressed and locked therein by the locking projection 34.

When the saw attachment 27 is removed, the spring arm 33 is deformed manually by the operator in the direction of the base plate 30, which enables the coupling structure of the saw attachment 27 to be released from the locking projection 34 and this saw attachment to be pulled out of the receptacle 35 in a direction parallel to the base plate 30. A used saw attachment 27 can be inserted into the holder particularly simply for temporary storage and/or cleaning, in which it can be simply pushed in again through the receptacle 35 in the direction of the locking projection 34, with the spring arm 33 being compressed until the locking projection 34 locks the coupling structure 29 of the saw attachment 27 and fixes the saw attachment in position in the holder 26.

The activation of the data carrier 42 can be implemented in the embodiments shown in fig. 9 and 10 as follows: each second clamping structure 32 forming a receiving recess may be designed/formed as a button. For example, each receiving recess has a rail or strand applied. The saw attachment 27 is arranged/formed such that it can be connected to a current circuit. This can preferably be achieved by producing the saw attachment 27 from an electrically conductive material, in particular metal, or by the saw attachment at least containing an electrically conductive layer, such as a layer of applied metal (in which case the saw attachment 27 is made of ceramic, plastic or a composite material). For example, when the saw attachment 27 is removed from the holding device 26, the current circuit can be closed (for a short time) by the saw attachment 27 and activate the data carrier 42.
