The identification signal receiving wire 113 and the identification signal transmitter 114 are connected in a manner that the two can be electrically connected all the time in the relative rotation process, so that the reliability of signal transmission is ensured, and the reliability of signal identification is further ensured.

It should be noted that the signal input end of the identification signal receiving lead 113 is connected with the sending end of the identification signal for transmitting the identification signal to the identification signal transmitter 114, and in the following description of an embodiment of the electric endoscopic stapler according to the present embodiment, the sending end of the identification signal is in the cartridge assembly 2, but of course, in other embodiments of the present invention, the sending end of the identification signal may also be disposed in the adaptor 1.

In this embodiment, the specific structure that the identification signal receiving wire 113 and the identification signal transmitter 114 can always keep electrical connection in the process of relative rotation between the two may be:

the adapter 1 further comprises a rotary electrical connector and a stationary electrical connector (the specific structure of both of which will be described later). The rotary electrical connector is fixed in the receiving cavity of the rotary body 112 in such a manner as to follow the rotation of the rotary body 112 along the axis of the rotary body 112, the identification signal receiving wire 113 is fixed with the rotary electrical connector, i.e., the identification signal receiving wire 113 rotates together with the rotary electrical connector, and the signal output end of the identification signal receiving wire 113 is electrically connected with the signal receiving end of the rotary electrical connector.

More specifically, as one embodiment of the rotating electrical connector and the stationary connector:

The fixed electrical connector is a second circuit board 117, a conductive ring coaxial with the axis of the rotating body 112 is formed on the second circuit board 117, and in the rotating process of the rotating electrical connector, the conductive elastic member 116 on the first circuit board 115 always presses against the conductive ring of the second circuit board 117 to always maintain the electrical connection between the rotating electrical connector and the fixed electrical connector, thereby ensuring the electrical connection between the identification signal receiving wire 113 and the identification signal transmitter 114 in the relative rotating process of the two.

In the embodiment, the conductive elastic members 116 and the conductive rings are respectively disposed on the opposite side surfaces of the first circuit board 115 and the second circuit board 117, and in order to ensure the stability of the electrical connection between the first circuit board 115 and the second circuit board 117, a plurality of conductive elastic members 11 are disposed corresponding to one conductive ring, and the plurality of conductive elastic members 116 are arranged with the axis of the rotating body 112 as a center. In addition, the conductive elastic members 116 of the same circle are connected by a wire, so that the stability of the electrical connection between the first circuit board 115 and the second circuit board 117 can be prevented from being influenced when one of the conductive elastic members 116 is in poor contact with the conductive ring. The first circuit board 115 and the second circuit board 117 may be in an annular structure disposed oppositely, but may also be in other structures as long as it is able to realize that when the rotary electrical connector rotates, the conductive elastic member 116 on the first circuit board 115 always presses against the conductive ring of the second circuit board 117 to always maintain electrical connection.

As an alternative to the above structure, as shown in fig. 5, the second circuit board 117 may be a circular plate, and the conductive ring is disposed on the circumferential surface of the second circuit board 117. When the rotary electrical connector rotates, the first circuit board 115 drives the conductive elastic member 116 to press against the conductive ring on the circumferential surface of the second circuit board 117, and the conductive elastic member is slidably connected to the conductive ring, so as to ensure the electrical connection between the first circuit board 115 and the second circuit board 117. At this time, the shape of the first circuit board 115 is not limited, and may be selected to be the same circular plate as the second circuit board 117, for easy installation.

Of course, contrary to the above embodiment, the rotating electrical connector may be the second circuit board 117 formed with the conductive ring, and the fixed electrical connector includes the first circuit board 115 and the conductive elastic piece, so as to ensure that, during the rotation of the rotating electrical connector, the conductive elastic piece 116 on the first circuit board 115 always presses against the conductive ring of the second circuit board 117 to always maintain the electrical connection.

Therefore, when the rotating body 112 rotates, the wire placing shell 119 is driven to rotate, so that the wire placing shell 119 rotates together with the identification signal receiving lead 113, a constraint is provided for the identification signal receiving lead 113, especially when the identification signal receiving lead 113 is long, the stability of the shape of the identification signal receiving lead 113 is ensured, the reliability of signal identification is further improved, and the identification signal receiving lead 113 is not worn.

In this embodiment, the rotating body 112 includes a rod body 1122 and a connecting body 1121, two ends of the connecting body 1121 are respectively connected to the rod body 1122 and the main body shell 111, and cavities are formed in both the connecting body 1121 and the rod body 1122, the cavities of the connecting body 1121 and the rod body 1122 are communicated to form an accommodating cavity of the rotating body 112, wherein the wire housing 119 is disposed in the cavity of the rod body 1122, the rotary electrical connector is disposed in the cavity of the connecting body 1121, and the identification signal receiving wire 113 penetrates through the two cavities of the rod body 1122 and the connecting body 1121. As shown in fig. 8, the connection body 1121 is externally connected to the main body housing 111, and a plurality of grooves are formed on the connection body 1121, and the grooves are engaged with the fingers of the operator, so that the operator can easily dial the connection body while holding the instrument with one hand.

As an alternative to the above-mentioned connection manner in which the connection body 1121 is externally connected to the main body housing 111, the connection body 1121 may be partially internally connected to the main body housing 111, and a separation groove is formed on an annular surface of an end of the connection body 1121 close to the operator, so as to facilitate the single-finger operation of the operator, but of course, the connection body 1121 may also be completely internally connected to the main body housing 111, as long as the connection body 1121 can drive the rod body 1122 to rotate. It should be noted that, when the connection body 1121 is externally connected to the main body housing 111, the connection body 1121 and the rod body 1122 serve as visible housings; when the connection body 1121 is partially inscribed in the main body housing 111, the exposed portion of the connection body 1121 and the rod body 1122 serve as a visible housing; when the connection body 1121 is completely inscribed in the body housing 111, the rod body 1122 serves as a visible housing.

Example two

As shown in fig. 8, the present embodiment further provides an electric endoscopic stapler, which includes the adaptor 1, the cartridge assembly 2 and the handle 3 in the above embodiments. The main body shell 111 of the adapter 1 is connected with the handle 3, the cartridge component 2 is detachably mounted on the rotating body 112 of the adapter 1, and the handle 3 and the cartridge component 2 are respectively arranged at two ends of the adapter 1.

Therefore, the transmission path of the identification signal sent by the identification signal generating structure is as follows: an identification signal receiving conductor 113, an identification signal transmitter 114, and a controller. In this case, the handle 3 is separately installed outside the adapter 1, but the adapter 1 and the handle 3 may be an integral structure.

As shown in fig. 9 to 10, in the present embodiment, the identification signal generating structure is an identification information storing chip 21, and the identification information storing chip 21 is disposed in the cartridge assembly 2. The identification information storage chip 21 stores specification information of the nail bin assembly 2, and the specification information is transmitted by taking an identification signal as a carrier, wherein the specification information comprises length information of the nail bin, nail height information in the nail bin, nail shape information in the nail bin, nail length information in the nail bin and nail anvil information in the nail bin.

In this embodiment, the identification information storage chip 21 is an EEPROM (electrically erasable and programmable read only memory), the EEPROM is disposed on the circuit board 22 of the magazine assembly 2, the identification signal receiving lead 113 is connected to the circuit board 22 through the elastic connection terminal 118, and the identification information is transmitted to the identification signal receiving lead 113 through the circuit board 22 and the elastic connection terminal 118 and then continuously transmitted backward. Since the identification information storage chip in this embodiment is an EEPROM, and the EEPROM is provided with two pins, two conductive rings and two conductive elastic members corresponding to the two conductive rings are provided to transmit the identification signal, and the number of the conductive rings may be set to be multiple according to actual needs.

In this embodiment, the adapter 1 further comprises a firing bar 122. In the practical application process, due to the fact that target tissues are different, preset information in the controller is different, wherein the preset information in the controller can be manually input or stored through near field identification, when the preset information in the controller is the same as information in the identification information storage chip 21, the controller controls the firing rod 122 to fire the nail bin assembly 2 according to specification information, and then the controller outputs firing completion information to the prompting device, and the prompting device reminds a user of completing firing, so that secondary firing of the user is avoided. When the specification information is different from the preset information in the controller, the controller controls the trigger rod 122 not to trigger. The prompting device can be a display, a flashing light or a player, and the like, as long as the prompting function can be realized. The firing bar 122 and the related firing structure are conventional and will not be described herein.
