Description

Technical Field

[0001] The utility model relates to the technical field of staplers, in particular to a stapler cartridge assembly. Background Art

[0002] Staplers are special surgical instruments designed based on the principle of staplers and used in surgical operations to replace traditional manual cutting and suturing. Staplers are divided into many types according to their uses and parts of use. There are usually three types of digestive tract staplers; the first is a circular stapler, the second is a linear cutting stapler, and the third is a linear suture stapler.

[0003] The patent number is CN201320245520.X, and the name is a stapler seat for a disposable intracavitary cutting stapler. The stapler is connected and installed using a card-embedded structure along the head and tail ends of the stapler seat. However, this connection method requires high processing accuracy of the card body and the groove body of the stapler and the stapler seat. If there is a size difference between the two, the installed stapler may shake in the head and tail ends of the stapler seat or the stapler may be difficult to embed into the stapler seat. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the problem in the prior art that the stapler adopts an embedding structure along the head and tail ends of the staple magazine seat for connection and installation, but this connection method requires high processing accuracy of the card body and the groove body of the staple magazine and the staple magazine seat. If there is a size difference between the two, the installed staple magazine may shake or the staple magazine may be difficult to embed into the staple magazine seat. A stapler assembly is provided.

[0005] The utility model solves the technical problem by adopting the following technical solution: a stapler assembly for a stapler, comprising a connecting rod, a stapler, a stapler seat and a staple anvil seat, wherein the tail end of the stapler seat is fixedly connected to the head end of the connecting rod, the tail end of the stapler seat is rotatably connected to the head end of the connecting rod, and the stapler seat can be docked and closed with the stapler seat after rotation, the stapler is installed on the stapler seat, the stapler is located between the stapler seat and the staple anvil seat, and the head end of the stapler protrudes from the head end of the stapler seat;

[0006] A fixing groove is provided on the bottom surface of the nail magazine, and the inner wall of the fixing groove has a groove docking surface inclined from top to bottom and outward. A fixing block protrudes from the top surface of the nail magazine seat, and the outer wall of the fixing block has a block docking surface inclined from top to bottom and outward. The inclination angle of the block docking surface is greater than the inclination angle of the groove docking surface. Through the design of the fixing groove and the upwardly protruding fixing block, the installation direction of the nail magazine is vertically installed along the nail magazine seat, so that it is fixed along the head and tail ends of the nail magazine seat.

[0007] In order to solve the problem of the nail magazine and the nail magazine seat being too deeply embedded, a limit block is further provided on the side wall of the nail magazine, and a limit groove matching the limit block is provided on the nail magazine seat, and the limit block is located in the limit groove.

[0008] It further includes that the groove depth of the limiting groove is smaller than the groove depth of the fixing groove.

[0009] It further includes limiting blocks on both sides of the nail magazine.

[0010] In order to solve the problem of the inconvenience of separating the nail magazine and the nail magazine seat, the nail magazine seat further includes a receiving portion on the head end surface thereof, which gradually shrinks from its upper end to its lower end toward the head end, and the bottom surface of the nail magazine has a receiving groove matching the receiving portion, and the receiving portion is located in the receiving groove.

[0011] It further comprises a fixing block having a truncated cone-shaped structure.

[0012] The beneficial effect of the utility model is that the stapler assembly provided by the utility model can be installed in the vertical direction of the stapler seat through the design of the fixing groove and the upwardly protruding fixing block, so as to achieve fixation in the direction of the head and tail ends of the stapler seat.

DETAILED DESCRIPTION

[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] like Figure 1 1 is a schematic diagram of the structure of the utility model, a stapler assembly, comprising a connecting rod 1, a stapler 2, a stapler seat 3 and a staple anvil 4, the tail end of the stapler seat 4 is fixedly connected to the head end of the connecting rod 1, the tail end of the stapler seat 3 is rotatably connected to the head end of the connecting rod 1, and the stapler seat 3 can be docked and closed with the stapler seat 4 after rotation, the stapler 2 is installed on the stapler seat 3, the stapler 2 is located between the stapler seat 3 and the stapler seat 4, and the head end of the stapler 2 protrudes from the head end of the stapler seat 3;

[0022] like Figure 3 , Figure 4 , Figure 5 As shown, a fixing groove 21 is provided on the bottom surface of the nail magazine 2, and a groove docking surface 211 inclined from top to bottom and outward is provided on the inner wall of the fixing groove 21. A fixing block 31 is protruded from the top surface of the nail magazine seat 3, and a block docking surface 311 inclined from top to bottom and outward is provided on the outer wall of the fixing block 31. The inclination angle of the block docking surface 311 is greater than the inclination angle of the groove docking surface 211. The installation is carried out in an interference fit manner, so that the installation and disassembly of the nail magazine 2 and the nail magazine seat 3 are convenient. The difference between the inclination angle of the block docking surface 311 and the inclination angle of the groove docking surface 211 is 1°-2°. The fixing block 31 is a truncated cone structure, and the end face area of ​​the fixing block 31 gradually increases from top to bottom, so that the installation method of the nail magazine 2 is changed to installation from top to bottom and disassembly from bottom to top, so that it is fixed along the head and tail end directions of the nail magazine seat 4.

[0023] like Figure 1 , Figure 2 As shown, a limit block 22 is provided on the side wall of the nail magazine 2, and a limit groove 32 matching the limit block 22 is provided on the nail magazine seat 3. The limit block 22 is located in the limit groove 32. The groove depth of the limit groove 32 is less than the groove depth of the fixing groove 21, which plays a limiting role to prevent the fixing block 31 and the fixing groove 21 from being too tight, but a space is left between the fixing block 31 and the fixing groove 21 to facilitate the subsequent disassembly and separation of the nail magazine 2 and the nail magazine seat 3. Limit blocks 22 are provided on both sides of the nail magazine 2, and support is provided on both sides to increase stability.

[0024] like Figure 1 , Figure 3 As shown, the head end surface of the nail magazine seat 3 has a receiving portion 33 which gradually shrinks from the upper end to the lower end toward the head end, and the bottom surface of the nail magazine 2 has a receiving groove 23 matching the receiving portion 33. The receiving portion 33 is located in the receiving groove 23, which increases the area of ​​the portion where the nail magazine 2 and the nail magazine seat 3 can be separated for the first time, which is beneficial to ensure the integrity of the nail magazine 2 and also facilitates the application of force to separate the nail magazine 2. The fixing block 31 is located on the receiving portion 3.

[0025] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
