Description

Technical Field

[0001] This utility model relates to the field of anastomosis device assembly technology, and in particular to an auxiliary device for anastomosis device assembly. Background Technology

[0002] The stapler, the world's first suture device, has been used for gastrointestinal anastomosis for nearly a century, but it wasn't until 1978 that the tubular stapler became widely used in gastrointestinal surgery. Staplers are generally classified as disposable or reusable, and imported or domestically produced. They are medical devices that replace traditional manual suturing. Due to advancements in modern technology and improvements in manufacturing techniques, clinically used staplers are reliable, easy to use, and provide a tight, appropriate fit. Their advantages, particularly their rapid suturing, ease of operation, and minimal side effects and surgical complications, have enabled the removal of previously inoperable tumors.

[0003] A search revealed Chinese utility model patent CN221186315U, an auxiliary device for assembling a stapler, relating to the field of stapler assembly. The device includes: a stapler assembly table; a lower clamping block welded and fixed to the upper surface of the assembly table; a drive screw mounted on the assembly table via a fixed side plate; a stepper motor shaft-connected to the rear end of the drive screw; an assembly pressure plate connected to the drive screw via a drive block; negative pressure suction holes formed on the side of the assembly pressure plate; a spring-loaded plate glued to the surface of the negative pressure suction holes; and an extension plate welded and fixed to the side of the assembly pressure plate. This utility model solves the problem in the prior art where the drive mechanism directly clamps the rear end of the stapler rod, affecting the assembly of the rear stapler body and making it difficult to quickly assemble and engage the stapler body and shell.

[0004] However, the housing of the stapler is not a flat structure. The prior art uses an assembly pressure plate, which is difficult to hold the housing with a curved structure. This causes the housing to slip easily during the assembly process, affecting the assembly efficiency and accuracy. In view of this, this application proposes a stapler assembly auxiliary device based on the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary device for anastomosis assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An auxiliary device for assembling a stapler includes a worktable. Two symmetrical support plates are fixedly mounted on the upper surface of the worktable. A bidirectional threaded rod is rotatably mounted between the support plates. A motor is fixedly mounted on one side of one of the support plates. The output end of the motor is fixedly connected to the bidirectional threaded rod. Two symmetrical nut seats are helically mounted on the bidirectional threaded rod. A movable plate is fixedly mounted on the nut seats. A rubber sponge is fixedly mounted on one side of the movable plate. Both the movable plate and the rubber sponge are provided with adsorption holes. A negative pressure pipe is fixedly connected to the other side of the movable plate. The negative pressure pipe is connected to the adsorption holes and is fixedly connected to an external vacuum generator.

[0008] Furthermore, a base is fixedly installed on the upper surface of the workbench, a first clamping block is fixedly installed at the center of the upper surface of the base, two symmetrical mounting slots are provided inside the base, an electric telescopic rod is fixedly installed in the mounting slot, a lifting plate is fixedly installed at the output end of the electric telescopic rod, and a second clamping block is fixedly installed between the lifting plates.

[0009] Furthermore, two symmetrical slide rails are fixedly installed on the upper surface of the worktable, and sliders are slidably installed on the slide rails, with the sliders being fixedly connected to the moving plate.

[0010] Furthermore, four fixing blocks are fixedly installed on one side of the movable plate, two of which have springs fixedly installed on their upper surfaces, and one end of each spring has an abutment plate fixedly installed on it.

[0011] Furthermore, both the first clamping block and the second clamping block have a V-shaped structure, and the first clamping block is provided with a relief groove, the width of which is greater than that of the second clamping block.

[0012] Furthermore, two symmetrical guide rods are fixedly installed on the upper surface of the base, and the lifting plate is slidably connected to the guide rods.

[0013] Furthermore, the adsorption pores include a first pore arranged laterally and a second pore arranged obliquely.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model sets up a negative pressure pipe, an adsorption hole, and a rubber sponge. The shell is attached to the rubber sponge. The deformation of the rubber sponge allows the curved shell to fit more closely between the two moving plates. The negative pressure pipe generates a negative pressure suction force, and under the action of the adsorption hole, the shell of the stapler is tightly adsorbed onto the moving plates.

[0016] 2. This utility model sets up a first clamping block and a second clamping block. The electric telescopic rod drives the lifting plate and the second clamping block to descend. The rod body is clamped between the first clamping block and the second clamping block. In order to accommodate rod bodies of different specifications, the second clamping block will not contact the inclined surface of the first clamping block when it descends, but will move in the relief groove. Therefore, it can clamp rod bodies of thinner specifications.

[0017] 3. By setting an abutment plate, the two shells of the anastomosis device are first placed against the abutment plate. The abutment plate is compressed by the weight of the shell, thereby adapting to the curved surface structure of the shell. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-2An auxiliary device for assembling a stapler includes a worktable 1. Two symmetrical support plates 2 are fixedly installed on the upper surface of the worktable 1. A bidirectional threaded rod 3 is rotatably installed between the support plates 2. A motor 4 is fixedly installed on one side of one of the support plates 2. The output end of the motor 4 is fixedly connected to the bidirectional threaded rod 3. Two symmetrical nut seats 5 are spirally installed on the bidirectional threaded rod 3. A movable plate 6 is fixedly installed on the nut seats 5. A rubber sponge 7 is fixedly installed on one side of the movable plate 6. Both the movable plate 6 and the rubber sponge 7 are provided with adsorption holes 8. A negative pressure pipe 9 is fixedly connected to the other side of the movable plate 6. The negative pressure pipe 9 is connected to the adsorption holes 8 and is fixedly connected to an external vacuum generator.

[0026] The shells are attached to the rubber sponge 7 respectively. The deformation of the rubber sponge 7 allows the curved shells to fit more closely between the two moving plates 6. Negative pressure suction is generated in the negative pressure pipe 9. Under the action of the adsorption hole 8, the shells of the stapler are tightly adsorbed onto the moving plate 6.

[0027] Reference Figure 1 , Figure 3-5 Specifically: A base 10 is fixedly installed on the upper surface of the workbench 1. A first clamping block 11 is fixedly installed at the center of the upper surface of the base 10. Two symmetrical mounting slots are provided inside the base 10. An electric telescopic rod 12 is fixedly installed in the mounting slot. A lifting plate 13 is fixedly installed at the output end of the electric telescopic rod 12. A second clamping block 14 is fixedly installed between the lifting plates 13. The rod of the stapler is placed on the first clamping block 11. The electric telescopic rod 12 is started. The electric telescopic rod 12 drives the lifting plate 13 and the second clamping block 14 to descend, and the rod is clamped between the first clamping block 11 and the second clamping block 14.

[0028] Reference Figure 1 , Figure 3 Specifically: two symmetrical slide rails 15 are fixedly installed on the upper surface of the workbench 1, and sliders 16 are slidably installed on the slide rails 15. The sliders 16 are fixedly connected to the moving plate 6.

[0029] Reference Figure 1-2 Specifically: Four fixing blocks 17 are fixedly installed on one side of the moving plate 6, and springs 18 are fixedly installed on the upper surface of two of the fixing blocks 17. An abutment plate 19 is fixedly installed on one end of the spring 18. The two shells of the anastomosis device are first leaned against the abutment plate 19. The abutment plate 19 is compressed by the gravity of the shell, thereby adapting to the curved structure of the shell.

[0030] Reference Figure 4-5Specifically: Both the first clamping block 11 and the second clamping block 14 are V-shaped structures. The first clamping block 11 is provided with a relief groove 20. The width of the relief groove 20 is greater than that of the second clamping block 14. In order to accommodate rods of different specifications, the second clamping block 14 will not contact the inclined surface of the first clamping block 11 when it descends, but will move within the relief groove 20. Therefore, it can clamp rods of thinner specifications.

[0031] Reference Figure 4 Specifically: two symmetrical guide rods 21 are fixedly installed on the upper surface of the base 10, and the lifting plate 13 is slidably connected to the guide rods 21.

[0032] Reference Figure 1-2 Specifically: the adsorption hole 8 includes a first hole 22 arranged horizontally and a second hole 23 arranged obliquely. Since the shell of the anastomosis device is similar to a gun-shaped structure, the first hole 22 can adsorb the straight part of the shell, while the second hole 23 adapts to the oblique part of the shell, ensuring a more stable adsorption.

[0033] Working principle: The two shells of the stapler are first placed against the abutment plate 19. The abutment plate 19 is compressed by the weight of the shells, thus adapting to the curved structure of the shells. Then, the shells are respectively attached to the rubber sponge 7. Through the deformation of the rubber sponge 7, the curved shells are more closely fitted between the two moving plates 6. Negative pressure suction is generated in the negative pressure pipe 9. Under the action of the suction hole 8, the shells of the stapler are tightly adsorbed onto the moving plates 6. Then, the rod of the stapler is placed on the first clamping block 11. The electric telescopic rod 12 is activated. The electric telescopic rod 12 drives the lifting plate 13 and the second clamping block 14 to descend. The body is clamped between the first clamping block 11 and the second clamping block 14. In order to accommodate rods of different specifications, the second clamping block 14 will not contact the inclined surface of the first clamping block 11 when it descends, but will move within the relief groove 20. Therefore, it can clamp rods of thinner specifications. At this time, the body of the stapler and the housing are on the same horizontal plane. The motor 4 is started, and the motor 4 drives the bidirectional threaded rod 3 to rotate. The two moving plates 6 move closer to each other under the drive of the nut seat 5 until the two stapler housings press against each other on the outside of the stapler body. Then the vacuum generator is disconnected, the motor 4 reverses, and the moving plate 6 returns to the initial position, finally realizing the assembly of the stapler body and the housing.
