Technical Field

The invention relates to the field of pipe breaking processing of a microtube by adopting a cutting blade, in particular to a cutting device in a pipe breaking processing technology (step) aiming at a microtube (such as an oviduct stripping) and the like.

Background

The glass microtubes or glass microneedles, such as fallopian tubes (or microtubular tubes, ovum-peeling needles) are generally manufactured by the process steps of tube pulling, tube breaking, polishing and the like, and most of the used blanks are glass tubes with the inner diameter of 1.5 mm. The cutting method adopted in the current production process of the glass display microtube is mainly cutting a piece of tube (needle) or cutting the tube (needle) on a calcinator. Taking the ovum peeling tube as an example, the cutting method mainly has the problem that the length of the ovum peeling tube of the finished product is poor. The problem that the tube (needle) of the calcining instrument is broken that the cutting process consumes more time, the production efficiency is low and only one tube can be broken at a time exists. The ovum peeling and cutting device for completing the broken needle by the cutting piece (or the grinding wheel piece) cuts the ovum peeling pipe by applying thermal shock while forming scratch by making the cutting piece contact with the outer circumference of the ovum peeling pipe.

The conventional dicing sheet cutting device has the following problems: since the dissecting sheet is merely brought into contact with the wall of the glass microcatheter such as the ovum-dissecting tube, fine glass particles generated during the dissection easily flow into the ovum-dissecting tube from the opening at the cross section, and the fine glass particles adhere to the inner surface of the tube, thereby contaminating the cleanliness of the inner wall of the ovum-dissecting tube. The problem of adhesion of fine glass particles to the inner surface of the tube wall is very important for medical instruments, such as fallopian tubes, experimental instruments, surgical instruments and the like, which pay particular attention to the cleanness of the inside of the tube. After the cutting treatment, the inner wall surface of the fallopian tube must be carefully cleaned.

Disclosure of Invention

Aiming at the problem of poor consistency of broken tubes in the process of cutting the pieces and breaking the tubes, the invention provides an automatic tube breaking device for a microtube, which solves the problem of movement of the microtube/an oviduct peeling tube in the tube breaking process by improving a clamping structure in the tube peeling and tube breaking process of a microtube, so as to better ensure that the lengths of the microtube/the oviduct peeling tube obtained by cutting have good consistency. In addition, a closed space capable of forming negative pressure flow is arranged in the cutting device, so that the problem that glass fine particles are easily attached to the inner wall of the microtube/oviduct peeling tube after the tube is broken is solved, and the good cleanness of the microtube/oviduct peeling tube obtained after the tube is broken is favorably ensured.

The technical scheme adopted by the invention for solving the technical problems is as follows: an automatic microtube breaking device comprises a workbench a and a workbench b which are arranged on a base, a pushing mechanism and a cutter, wherein the cutter is arranged at the distance between the two workbenches; when the tube is broken, the micro-tube/ovum-peeling tube is placed on the workbench a, the pushing mechanism pushes the tip end of the micro-tube/ovum-peeling tube to move a certain length to the workbench b, and then the cutter cuts off the micro-tube/ovum-peeling tube.

Still including establishing slip table on the workstation a and establish briquetting mechanism an directly over the slip table, and establish briquetting mechanism b directly over workstation b. The upper end surface of the sliding table is provided with a plurality of lugs A which are arranged at intervals, and the workbench b below the block pressing mechanism b is provided with a plurality of lugs a which are arranged at intervals.

The microscopic tube/oviduct stripper can be clamped in the gap formed between two adjacent convex blocks A, and the pressing block mechanism a can apply downward pressure on the microscopic tube/oviduct stripper. The pushing mechanism can push the sliding table carrying the display microtubes/the fallopian tubes to move towards the workbench b, and the pressing block mechanism a and the sliding table can synchronously move in the process.

The tip end of the microtube/oviduct stripper can penetrate through the gap formed between two adjacent convex blocks a, and the middle part of the microtube/oviduct stripper is clamped in the gap formed between the convex blocks a, and the pressing block mechanism b can apply downward pressure to the microtube/oviduct stripper.

When the micro-tube/oviduct stripper is clamped between two adjacent lugs A or between two adjacent lugs a, the upper side of the outer wall of the tube body is exposed out of the top surfaces of the lugs, and the upper side of the outer wall of the tube body gradually moves downwards along with the pressing block mechanism a (a pressing block or a pressing plate) and gradually moves downwards along with the pressing block mechanism b (a pressing block or a pressing plate), so that each pressing block mechanism can gradually contact with the upper side of the outer wall of the tube body (of the micro-tube/oviduct stripper), and finally, a larger pressing action force can be applied to the micro-tube/oviduct stripper.

In the above embodiment, after the microtube/oviduct is clamped between two adjacent lugs a and between two adjacent lugs a, the upper side of the tube wall is exposed outside the lugs. The pressing block of the pressing block mechanism a and the pressing block of the pressing block mechanism b can be lifted in the plumb direction, so that each pressing block can be selectively close to or far away from the table surface of the workbench a or the table surface of the workbench b. And a layer of resin rubber pad or rubber pad is fixedly arranged on the lower end face of the pressing block mechanism a and/or the lower end face of the pressing block mechanism b so as to increase the static friction resistance when the pressing block mechanism is in contact with the tube wall of the display microtube/the fallopian tube. After the microtubes/oviduct dissections are arranged between two adjacent convex blocks A, the two convex blocks A form smaller clamping force on the oviduct dissections, and the formed clamping force is too large, so that the microtubes/oviduct dissections are difficult to place between the two adjacent convex blocks A, and the phenomenon of movement during placement is avoided. Therefore, the micro-tube/oviduct dissecting is relatively fixed on the sliding table by the clamping structure formed by the adjacent convex blocks A, and the aim of preventing the micro-tube/oviduct dissecting from moving axially relative to the sliding table is fulfilled by the pressing block in the pressing block mechanism a contacting with the micro-tube/oviduct dissecting and applying downward pressure on the micro-tube/oviduct dissecting. When the microscopic tube/oviduct is pushed to gradually pass between two adjacent bumps a, the tube wall will gradually contact with the side walls of the bumps a. The requirement that the two lugs a provide less grip on the microscope tube/oviduct than lug a provides on the microscope tube/oviduct, generally requires only contact, so as to avoid excessive sliding resistance of the lugs a as the microscope tube/oviduct passes axially between the two lugs a. And finally, the pressing block in the pressing block mechanism b is contacted with the microtube/the oviduct-peeling pipe and applies downward pressure to the microtube/the oviduct-peeling pipe, so that the aim of preventing the microtube/the oviduct-peeling pipe from axially shifting relative to the sliding table is further fulfilled. Finally, the micro-tube displaying/fallopian tube is reliably fixed between the two working tables, and the phenomenon that the micro-tube displaying/fallopian tube has axial movement is not easy to occur when the micro-tube displaying/fallopian tube is cut off, and the phenomenon that the micro-tube displaying/fallopian tube rotates around the axis of the micro-tube displaying/fallopian tube is not easy to occur, so that the cutting off process is ensured to be smoothly finished.

The sliding table can be used for simultaneously placing a plurality of (semi-finished) microtubes/fallopian tubes side by side, so that the production efficiency of broken tubes can be improved greatly, the consistency of the processing length is ensured, and the production cost is reduced. Whether one or more (semi-finished) microtubes/tubal dissections are placed on the sliding table, the length of the tip end of the microtube/tubal dissection relative to a front feeding clamp is generally required to be set in a front feeding procedure, and a preset precondition for good consistency of the tubal dissections obtained by subsequent cutting is provided. After the (semi-finished) microscopic tube/oviduct peeling tube is fed onto the sliding table through the feeding mechanism in the pre-procedure, the axial distances of the tip end ports of the (semi-finished) microscopic tube/oviduct peeling tube relative to the (left and right) side surfaces of the sliding table are consistent and can be relatively distributed on the same straight line (extending along the front-back direction).

And a sliding table structure can be arranged on the workbench b by referring to the workbench a, and a pulling mechanism matched with the sliding table structure is configured for moving the micro-tube displaying/oviduct peeling device to the other side (the side departing from the workbench a) of the workbench b after the cutting is finished so as to be grabbed by the feeding mechanism of the next process. The protrusion block a is arranged on the table top of the sliding table structure. When the pulling mechanism pulls the sliding table structure to move, the pressing block mechanism b can move synchronously with the sliding table structure.

Further, the negative pressure flow assembly is installed between the workbench a and the workbench b. The negative pressure flow assembly comprises an upper cavity, a lower cavity and a collecting cavity, and the cutter is fixedly arranged in the upper cavity.

The lower port on the upper cavity is opposite to the upper port on the lower cavity, and a circle of elastic cushion layer is respectively arranged outside the two ports. The elastic cushion layer on the upper cavity and the elastic cushion layer on the lower cavity can synchronously lift along with the cavity, so that the elastic cushion layer on the upper cavity and the elastic cushion layer on the lower cavity can be selectively close to and separated from each other.

The micro-tube/fallopian tube passes through the port of the upper cavity and the port of the lower cavity, the elastic cushion layer on the upper cavity and the elastic cushion layer on the lower cavity can clamp the micro-tube/fallopian tube in the middle and can be pressed together to enable the cavities of the upper cavity and the lower cavity to form a closed cavity.

The cavity of the lower cavity is communicated with the collecting cavity through a hose. The collection cavity is connected with a pump which can suck the air in the closed cavity formed by the collection cavity, the upper cavity and the lower cavity to continuously flow so as to form unidirectional flowing (negative pressure) airflow, so that the glass fine particles are taken away from the micro-tube/the oviduct peeling part and are concentrated in the collection cavity. During this period, the suction effect of the pump can cause a negative pressure to be formed in the cavity of the collection chamber and in the cavity of the closed chamber formed by the upper and lower chambers.

Furthermore, the periphery of the upper cavity is provided with a sliding sleeve, and the elastic cushion layer is arranged on the lower end face of the sliding sleeve. And a sealing ring is arranged between the sliding sleeve and the wall surface of the upper cavity. The top surface of the upper cavity is provided with a lifting motor a provided with a wire lever, and the wire lever at the position is matched with the sliding sleeve to enable the lifting motor a to drive the sliding sleeve to lift.

Further, the lower cavity is installed between the workbench a and the workbench b or on the workbench b through a connecting frame. The lower part of the lower cavity is formed into a tubular part, the port of the tubular part is communicated with the collection cavity through a hose, and the exterior of the tubular part is matched with a connecting sleeve. The lower end of the connecting frame is provided with a lifting motor b provided with a wire lever, and the wire lever at the position is matched with the connecting sleeve to enable the lifting motor b to drive the lower cavity to lift.

Furthermore, the cavity of the lower cavity is a conical cavity, and the necking end of the cavity is downward.

Further, the upper cavity and the lower cavity are both installed on the workbench b through connecting frames.

The workbench a is matched with the base through the supporting sliding table, the cylinder rod unit capable of driving the supporting sliding table to slide in a reciprocating mode along a straight line is installed on the base, and the workbench a can be selectively far away from and close to the workbench b.

The workbench b is matched with the base through the supporting table, the supporting table is close to one end of the supporting sliding table is matched with the hydraulic cylinder a, and the end of the supporting sliding table is matched with the hydraulic cylinder b. The hydraulic cylinders a and b can keep the table top of the support table in a horizontal state or a tilting state.

Further, the pump is mounted atop the collection chamber. The middle part of the collecting cavity is provided with a clapboard, and a cavernous body is filled in the cavity above the clapboard. And a connecting pipe with one end connected with the lower cavity and the other end extending to the lower part of the clapboard is arranged in the collecting cavity.

Further, the cavity below the partition board is filled with fluffy floccules, such as cotton, absorbent cotton, and similar artificial fibers, such as polyester fibers.

Furthermore, the upper cavity is provided with a coding motor which is provided with a wire lever, and the axial direction of the wire lever is vertical to the axial direction of the oviduct peeling tube which is arranged on the sliding table.

The lower part of a sliding block arranged on the screw lever is provided with a connecting seat, and the connecting seat is provided with a sliding seat and a first motor driving the sliding seat to reciprocate through a linear track in a matching way. The moving direction of the sliding seat is consistent with the axial direction of the fallopian tube arranged on the sliding table.

The sliding seat is connected with a bearing seat bearing the cutter, and a driving unit capable of driving the bearing seat to lift is arranged on the sliding seat.

The invention has the beneficial effects that: aiming at the problem of poor consistency of the length of the broken tube obtained by cutting in the prior device for cutting the broken tube by the cutting piece, the automatic tube cutting device for the microtube provided by the patent improves a clamping structure in the process of cutting the microtube/the oviduct peeling tube to solve the problem of the oviduct peeling tube movement in the process of tube cutting and ensure that the length of the microtube/the oviduct peeling tube obtained by cutting has good consistency. In view of the problem that fine glass particles are easily adhered to the inner wall of the tube in the conventional device for cutting a microscopic tube/fallopian tube, the present patent application also provides a structural scheme capable of reliably preventing the problem of the cleanliness of the fallopian tube caused by adhesion of the fine glass particles to the inner surface of the tube wall.

In addition, the terms "upper", "lower", "front", "rear" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.

An automatic microtube cutting device as shown in fig. 1 is described below by taking a microtube, such as a fallopian tube, as an example.

The automatic pipe breaking device comprises a workbench a1 and a workbench b2 which are installed on a base 10, a sliding table 3 arranged on the workbench a1, a briquetting mechanism a5 arranged right above the sliding table 3, a briquetting mechanism b8 arranged right above the workbench b2, a pushing mechanism 4 and a cutter (not shown, and a known cutter is selected). The cutter is placed at the distance of the two tables 1, 2. When the tube is broken, the ovum-peeling tube 100 is placed on the workbench a1, the pushing mechanism 4 pushes the tip end of the ovum-peeling tube to move a certain length on the workbench b2, and then the cutter cuts off the ovum-peeling tube 100.

The pressing block of the pressing block mechanism a5 and the pressing block of the pressing block mechanism b8 can be lifted and lowered in the plumb direction, so that each pressing block can be selectively close to or far away from the table surface of the working table a1 or the table surface of the working table b 2. A layer of resin rubber pad or rubber pad is fixedly arranged on the lower end face of the pressing block mechanism a5 and/or the lower end face of the pressing block mechanism b8, so that the static friction resistance when the pressing block mechanisms 5 and 8 are in contact with the tube wall of the fallopian tube 100 is increased.

A plurality of lugs a31 arranged at intervals are arranged on the upper end surface of the sliding table 3, and a plurality of lugs a21 arranged at intervals are arranged on the workbench b2 below the briquetting mechanism b 8.

The oviduct stripper 100 can be clamped in the gap formed between two adjacent lugs a31, and the pressing mechanism a5 can apply downward pressure to the oviduct stripper 100. The pushing mechanism 4 can push the sliding table 3 carrying the oviduct peeling tube 100 to move towards the workbench b2, and the briquetting mechanism a5 can move synchronously with the sliding table 5. The pushing mechanism 4 is connected with the sliding table 3 and can drive the sliding table 3 to reciprocate relative to the workbench a1 along the left-right direction.

When the pushing mechanism 4 pushes the sliding table 3 to carry the oviduct peeling pipe 100 to move towards the side of the workbench b2, the tip end of the oviduct peeling pipe 100 can gradually penetrate through the gap formed between the two adjacent protruding blocks a21, and the middle part of the oviduct peeling pipe 100 is clamped in the gap formed between the two protruding blocks a21, and at the moment, the pressing block mechanism b8 can apply downward pressure to the oviduct peeling pipe 100.

After the tubal wall 100 is caught between the adjacent two projections a31 and between the adjacent two projections a21, the upper side of the tubular wall is exposed outside the projections 21, 31.

In the above embodiment, the two protrusions A31 are required to have limited (less) clamping force on the fallopian tube 100 after the fallopian tube 100 is placed between the two adjacent protrusions A31, because too much clamping force is likely to cause difficulty in placing the fallopian tube 100 between the two adjacent protrusions A31. Therefore, the oviduct peeling pipe 100 is relatively fixed on the sliding table 3 by the clamping structure formed by the adjacent convex blocks a31, and the press block in the press block mechanism a5 is contacted with the oviduct peeling pipe and applies downward pressure to the oviduct peeling pipe 100, so as to achieve the purpose of preventing the oviduct peeling pipe 100 from moving in the axial direction relative to the sliding table 3. When the fallopian tube 100 is pushed through between two adjacent lobes a21, the wall of the tube will gradually contact the side wall of the lobe a 21. The requirement that the two tabs a21 provide a more limited gripping force on the fallopian tube 100 (less than the gripping force provided by tab a31 on the fallopian tube 100) generally requires only contact to avoid axial play caused by the relatively large sliding resistance provided by tab a21 as the fallopian tube 100 passes axially between the two tabs a 21. Finally, the purpose of preventing the fallopian tube 100 from axially shifting relative to the sliding table 3 is further realized by means of the pressing block in the pressing block mechanism b8 contacting with the fallopian tube 100 and applying downward pressure to the fallopian tube 100. Finally, the oviduct peeling tube 100 is reliably fixed between the two working tables 1 and 2, and the phenomenon that the oviduct peeling tube 100 moves axially and the phenomenon that the oviduct peeling tube 100 rotates around the axis are not easy to occur when the oviduct peeling tube is cut off, so that the smooth completion of the cutting process is ensured.

As shown in fig. 1, a plurality of (semi-finished) fallopian tubes 100 can be simultaneously placed side by side on the sliding table 3, so that the production efficiency of broken tubes can be greatly improved, the consistency of the processing length is ensured, and the production cost is reduced. Generally, 5 to 10 fallopian tubes can be cut off one after another. Whether one or more (semi-finished) fallopian tubes 100 are placed on the sliding table 3, the length of the tip end of each fallopian tube relative to the front feeding clamp is required to be set in the front feeding process, and the preset premise of good consistency of the fallopian tubes obtained by subsequent cutting is provided. Namely, after the (semi-finished) fallopian tube is fed onto the sliding table through the feeding mechanism in the pre-process, the axial distance between the tip end port of the (semi-finished) fallopian tube and the (left and right) side surface of the sliding table is consistent. As shown in fig. 1, after a plurality of fallopian tubes 100 placed side by side on the slide table 3 are fixed on the slide table 3, the tip ports of the respective fallopian tubes 100 are aligned at the O-O line, and the axial distance from the O-O line to the right side surface of the slide table is fixed. When the front feeding mechanism places the next group of oviduct peeling pipes on the sliding table 3, the tip end port of each oviduct peeling pipe 100 is still aligned at the O-O line.

The front feeding mechanism can be a known feeding device. If the front feeding mechanism cannot ensure that the tip ports of the fallopian tubes placed on the sliding table 3 are on the same straight line extending back and forth (the axes of the fallopian tubes are perpendicular to the straight line), a tube arranging mechanism is required to be configured in the scheme of the patent, and the tip ports of the fallopian tubes placed on the sliding table 3 can be aligned on the same straight line (such as the illustrated O-O line). After the tube-adjusting mechanism completes the tube adjustment, the tube-pressing mechanism a5 applies pressure to the oviduct-peeling tube, so that the oviduct-peeling tube is reliably fixed relative to the sliding table 3. In conclusion, the precondition that the scheme can ensure good consistency of the oviduct peeling tube obtained by tube breakage is that the oviduct peeling tip port arranged on the sliding table can be aligned in advance or aligned by an additionally arranged tube arranging mechanism. How to complete the alignment of the fallopian tube is not considered to be solved in the patent, so detailed description of the embodiment is omitted.

As long as the oviduct peeling pipe with the tip end port capable of being kept in a relative alignment state is placed on the sliding table, the consistency of the obtained oviduct peeling pipe length after the oviduct peeling process is completed can be ensured by means of the method for implementing the oviduct peeling process.

On the workbench b, a sliding table structure can be arranged by referring to the workbench a, and a pulling mechanism matched with the sliding table structure is configured, so that after the cutting is completed, the fallopian tube can be moved to the other side (the side departing from the workbench a) of the workbench b to be grabbed by the feeding structure of the next process. The protrusion block a is arranged on the table top of the sliding table structure. When the pulling mechanism pulls the sliding table structure to move, the pressing block mechanism b can move synchronously with the sliding table structure.

As shown in fig. 1 to 5, a negative pressure flow assembly 6 is provided between the table a1 and the table b 2.

The negative pressure flow assembly 6 comprises an upper cavity 61, a lower cavity 62 and a collection cavity 9, and the cutter is fixedly installed in the upper cavity 61 (the connection structure is shown in fig. 1 and 2). At this time, the cutting blade on the cutter can be lifted (in the direction of the plumb) to be close to or far away from the oviduct peeling pipe.

The lower port of the upper cavity 61 is opposite to the upper port of the lower cavity 62, and a circle of elastic cushion 63 is respectively arranged outside the two ports. The elastic cushion 63 on the upper cavity 61 and the elastic cushion 63 on the lower cavity 62 can be lifted and lowered to selectively enable the elastic cushion 63 on the upper cavity 61 and the elastic cushion 63 on the lower cavity 62 to approach and separate from each other. The cavity of the lower cavity 62 is a tapered cavity 621 with a downward necking end. As illustrated, the entire lower cavity 62 is funnel-shaped.

As shown in fig. 3 to 5, a sliding sleeve 611 is disposed on the periphery of the upper cavity 61, and an elastic cushion 63 (disposed on the upper cavity 61) is disposed on the lower end surface of the sliding sleeve 611. And a sealing ring is arranged between the sliding sleeve 611 and the wall surface of the upper cavity 61. The top surface of the upper cavity 61 is provided with a lifting motor a612 equipped with a wire lever, and the wire lever is matched with the sliding sleeve 611, so that the lifting motor a612 can drive the sliding sleeve 611 to lift, and the elastic cushion 63 arranged on the upper cavity 61 is lifted. In fig. 3, the upper chamber 61 may be fixed to the base or the tables 1, 2. In fig. 4, the upper chamber 61 is connected to a table b2 by a connecting frame b67 and can move along with a table b 2.

As shown in fig. 3 and 5, the lower chamber 62 is mounted between the table a1 and the table b2 by a connecting frame a 66. As shown in fig. 4, the lower chamber 62 is mounted on the table b2 by a connecting bracket b 67. The lower part of said lower chamber 62 is formed as a tubular element, the port of which communicates with said collection chamber 9 via a hose and the exterior of which is fitted with a connecting sleeve 64. The lower ends of the connecting frame a66 and the connecting frame b67 are provided with a lifting motor b65 provided with a wire lever, and the wire lever is matched with the connecting sleeve 64, so that the lifting motor b65 can drive the lower cavity 62 to lift.

The oviduct peeling pipe 100 passes through the port of the upper cavity 61 and the port of the lower cavity 62, the elastic cushion 63 on the upper cavity 61 and the elastic cushion 63 on the lower cavity 62 can clamp the oviduct peeling pipe 100 in the middle, and the two elastic cushions 6 can be pressed together to enable the cavities of the upper and lower cavities 61 and 62 to form a closed cavity.

The cavity of the lower cavity 62 is communicated with the collection cavity 9 through a hose. The collection chamber 9 is connected to a pump 91, and the pump 91 can suck the air flow in the closed chamber formed by the collection chamber 9 and the upper and lower chambers 61, 62 to form negative pressure (air) flow. Fine glass particles generated during the cutting are drawn into the collection chamber 9 along with the air flow.

The glass fine particles generated in the tube breaking process are directly taken away by means of air flow, and when a gap is cut on the tube wall of the microtube (a section in the closed cavity), external air can flow into the microtube from the needle-shaped end to blow the inner wall, so that a small amount of glass fine particles falling on the inner wall of the microtube are cleaned. With the operation of the pump 91, a continuous negative pressure flow can be generated in the chamber formed by the two chambers 61, 62 facing each other and in the collecting chamber 9. The fine glass particles generated during cutting the fallopian tube are sucked away in time and collected in the collecting cavity 9, so that the fine glass particles can be reliably prevented from adhering to the inner wall of the fallopian tube, and the cleanness of the inner wall of the fallopian tube can be reliably ensured.

When a slit is cut in the tube wall of the fallopian tube, the suction action of the pump 91 flows into the inner wall of the air flow purging tube from the tip port of the fallopian tube, so that the fine glass particles attached near the cut port of the tube are cleaned.

As shown in fig. 4, the upper chamber 61 and the lower chamber 62 are mounted on the table b2 by a connecting frame b 67. The workbench a1 is matched with the base 10 by means of the supporting sliding table 11, and the base 10 is provided with a cylinder rod unit 12 (a pneumatic cylinder group or a hydraulic cylinder group or other linear transmission mechanism which can drive the supporting sliding table to move by means of a push rod) which can drive the supporting sliding table 11 to slide back and forth along a straight line, so that the workbench a1 can be selectively far away from and close to the workbench b 2. The workbench b2 is matched with the base 10 through the support table 22, a hydraulic cylinder a23 is matched at one end, close to the support sliding table 11, of the support table 22, and a hydraulic cylinder b24 is matched at one end, away from the support sliding table 11. The hydraulic cylinder a23 and the hydraulic cylinder b24 can keep the table top of the support table 22 in a horizontal state or a tilted state by controlling the extension and contraction of a cylinder rod of the hydraulic cylinder.

In the embodiment described in the above paragraph, after the tube breaking operation is completed for all the tubes 100 to be stripped on the sliding table 3, the supporting sliding table 11 is driven by the cylinder rod unit 12 to move to the left, so that the cut sections of the tubes close to the sliding table 3 are gradually removed from the cavities 61 and 62 (the elastic cushion 63 has a certain thickness, the elastic cushion 63 can deform and give way to envelop the outer wall of the tubes during clamping of the tubes, and after the tubes are removed from the finger space of the elastic cushion 63, the elastic cushion 63 can restore to the original shape to block the openings formed by clamping the tubes). The other end of the cross-section remains in the cavities 61, 62. The cylinder rod of the hydraulic cylinder b24 is extended and the cylinder rod of the hydraulic cylinder a23 is contracted, so that the workbench b2 is inclined towards the left side, and the axis of the obtained oviduct peeling pipe after the pipe is broken is inclined towards the lower left side, which is helpful for ensuring that the adhered glass fine particles are better cleaned.

As shown in fig. 3 to 5, the pump 91 is mounted on top of the collection chamber 9. The middle part of the collection cavity 9 is provided with a clapboard, and a cavernous body 93 is filled in the cavity above the clapboard. A connecting pipe 92 with one end connected with the lower cavity 62 and the other end extending to the lower part of the clapboard is arranged in the collection cavity 9. This structure can prevent fine glass particles sucked into the collection chamber 9 from flowing into the pump 91. Further, fluffy floccules, such as cotton and absorbent cotton, are filled in the cavity below the partition plate, so that the glass fine particles sucked into the collecting cavity 9 can be enveloped in the floccules, which is helpful for cleaning the collecting cavity on one hand, and can further prevent the glass fine particles from flowing into the pump 91 on the other hand.

As shown in fig. 1 and 2, the upper chamber 61 is provided with a coding motor 7 configured with a wire lever, and an axial direction of the wire lever 71 is perpendicular to an axial direction of the oviduct peeling tube 100 arranged on the sliding table 3.

The lower part of the slide block 72 arranged on the wire lever 71 is provided with a connecting seat 74, and the connecting seat 74 is provided with a sliding seat 75 and a first motor 76 driving the sliding seat 75 to reciprocate through a linear track. The moving direction of the slide carriage 75 coincides with the axial direction of the fallopian tube 100 disposed on the slide table 3.

The slide base 75 is connected to a bearing base bearing the cutter, and a driving unit (a second motor 77 is shown in the figure, and the second motor 77 is matched with a lead screw transmission structure to form a lead screw slider transmission mechanism with the bearing base) capable of driving the bearing base to ascend and descend is arranged on the slide base 75.

The coding motor 7 drives the cutters to move in the front-back direction through a lead screw transmission unit formed by a lead screw lever 71 and a slide block 72, so that the cutters respectively correspond to the upper parts of the respective oviduct peeling pipes. The first motor 76 drives the slide base 75 to move in the left-right direction (the direction of the tubal dissection axis) relative to the connecting base 74, so as to control the length of the tubal dissection required for the tubal disruption. The second motor 77 controls the carrier base to move up and down relative to the sliding base 75 so that the cutting blade of the cutter can act on the tube wall of the fallopian tube and the tube wall far away from the fallopian tube. The slide 72 is also provided with a set of guide rods 73 parallel to the wire lever 71, by means of which guide rods 73 the direction of movement of the slide 72 (or the connecting socket, the cutter) is guided.
