[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a pre-compression plate for stapling a stapler cartridge.

[0037] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] Example 1

[0039] Reference Figure 1 A pre-compression plate for stapler staple cartridge includes a plate body 1, which is provided with an assembly groove 11. The assembly groove 11 is adapted to the shape of the staple, and a guide slope 12 is provided on the inner wall of the assembly groove 11.

[0040] When the side of the plate 1 away from the guide bevel 12 contacts the staple cartridge, the assembly slot 11 communicates with the receiving slot on the staple cartridge, so that when the staples are assembled into the staple cartridge, the staples pass through the assembly slot 11 and enter the receiving slot. During this process, the guide bevel 12 can guide the staples accurately into the assembly slot 11, so that the staples are accurately inserted into the receiving slot, thereby reducing the possibility of damage to the staples due to inaccurate staple alignment, simplifying the stapling process to a certain extent, and improving operational efficiency.

[0041] There are multiple assembly grooves 11, and the multiple assembly grooves 11 can be divided into two groups. The two groups of assembly grooves 11 are symmetrically distributed on the plate body 1, and the multiple assembly grooves 11 in each group are evenly distributed along the length direction of the plate body 1, so that the pre-compression plate can adapt to nail magazines of different lengths, which increases the applicability and flexibility of the pre-compression plate to a certain extent.

[0042] In this embodiment, each assembly groove 11 is adapted to the design of a single-toothed staple, and a clearance groove 13 is provided on the inner wall of the assembly groove 11. The clearance groove 13 is adapted to the design of the staple foot, so that when the staple is inserted into the assembly groove 11, the staple foot can be inserted into the clearance groove 13, so that the inner wall of the clearance groove 13 guides the staple foot, so that the staple is accurately inserted into the assembly groove 11, thereby facilitating the accurate assembly of the staple into the staple magazine.

[0043] Reference Figure 1 and Figure 2A avoidance groove 14 is provided on the side of the plate body 1 away from the guide inclined surface 12. The avoidance groove 14 is provided along the length direction of the plate body 1, and the avoidance groove 14 is connected to the assembly groove 11. On the one hand, the assembly groove 11 can be more flexibly matched with the nail magazine and can be adapted according to the specific size and shape of the nail magazine, thereby improving the flexibility and adaptability of assembly. On the other hand, it helps to smoothly transport and position the anastomotic staples, especially when precise docking is required between the nail magazine and the assembly groove 11. The avoidance groove 14 can provide additional space to ensure the smooth passage of the anastomotic staples.

[0044] A positioning bar 15 is integrally formed on the side of the plate 1 away from the guide ramp 12. The positioning bar 15 is provided along the length of the plate 1. When the plate 1 contacts the staple cartridge, the positioning bar 15 can be inserted into the cutting groove of the staple cartridge and fit against the inner wall of the cutting groove. This not only provides a stable reference for improving positioning accuracy during assembly, but also helps reduce movement or offset of the plate 1 during assembly, thereby improving the stability of the entire assembly structure.

[0045] In this embodiment, the end of the positioning bar 15 away from the plate body 1 is tapered, so that when the plate body 1 contacts the nail magazine, the positioning bar 15 can be smoothly inserted into the cutting groove on the nail magazine to achieve positioning of the plate body 1.

[0046] Reference Figure 1 A number of positioning holes 16 are provided on the plate body 1, and the positioning holes 16 are located between the two sets of assembly grooves 11, which can provide a stable fixing point for the nail magazine to improve the connection stability between the nail magazine and the plate body 1, and enable the nail magazine and the plate body 1 to be accurately aligned, thereby further improving the reliability of the overall structure.

[0047] Mounting plates 2 are integrally formed on both sides of the plate 1. Mounting holes 21 are provided in the mounting plates 2 for bolts to pass through. When the plate 1 needs to be fixed to a specific location on the production line, bolts can be used to secure the plate 1 so that it contacts the staple cartridge after it enters the production line.

[0048] The implementation principle of the pre-compression plate for stapling a stapler staple cartridge of the embodiment of the present application is as follows: when the plate body 1 contacts the staple cartridge and the staples are assembled into the staple cartridge, the staples will pass through the assembly slot 11 and enter the receiving slot. During this process, the guide slope 12 can guide the staples into the assembly slot 11 and enable the staple legs to be inserted into the yielding slot 13, so that the staples can accurately enter the assembly slot 11 and be inserted into the receiving slot on the staple cartridge through the assembly slot 11, thereby achieving precise assembly of the staples.

[0049] Example 2

[0050] Reference Figure 3The difference between this embodiment and embodiment 1 is that there are two assembly grooves 11, the two assembly grooves 11 are symmetrically arranged, and each assembly groove 11 is opened along the length direction of the plate body 1.

[0051] The inner wall of the assembly groove 11 is provided with a plurality of protrusions 17 along its length. The plurality of protrusions 17 are divided into two groups, and the two groups of protrusions 17 are fixedly connected to the inner walls on both sides of the assembly groove 11, and the two groups of protrusions 17 are staggered. In this embodiment, the assembly groove 11 is adapted to a double-toothed anastomotic staple design.

[0052] The provision of multiple protrusions 17 can more firmly fix the double-toothed staples, ensuring that the staples will not be displaced or rotated during the assembly process, thereby helping to improve the stability and reliability of the assembly. The multiple protrusions 17 are staggered so that the assembly groove 11 can adapt to double-toothed staples of different shapes and sizes, further improving the versatility and adaptability of the pre-load plate.

[0053] Example 3

[0054] Reference Figure 4 The difference between this embodiment and embodiment 2 is that a partition block 3 is detachably connected to the plate body 1.

[0055] Reference Figure 4 and Figure 5 A card slot 18 is provided on the plate body 1 , and there are two card slots 18 , which are symmetrically distributed at both ends of the plate body 1 .

[0056] The separator 3 is fixedly connected to an elastic clamping block 31. When the separator 3 needs to be connected to the plate body 1, the separator 3 is first inserted into the assembly groove 11 so that the separator 3 contacts the plate body 1. At the same time, the elastic clamping block 31 is inserted into the clamping groove 18 and clamped to the plate body 1, thereby connecting and fixing the separator 3 to the plate body 1.

[0057] When the partition block 3 is connected to the plate body 1, the partition block 3 contacts the protrusion 17, so that the partition block 3 can divide the assembly groove 11 into multiple installation grooves 19. In this embodiment, the installation groove 19 is adapted to a single-toothed anastomotic staple design.

[0058] When the single-tooth anastomosis staple needs to be assembled into the staple cartridge, the partition block 3 is first connected to the plate body 1 to separate the assembly groove 11 into the installation groove 19 , thereby facilitating the single-tooth anastomosis staple to be assembled into the staple cartridge through the installation groove 19 .

[0059] When it is necessary to assemble the double-toothed staples into the staple cartridge, the partition block 3 is removed from the plate body 1 so that the assembly groove 11 can adapt to the double-toothed staples, so that the double-toothed staples can be assembled into the staple cartridge through the assembly groove 11. This helps to quickly adjust the layout of the assembly groove 11 as needed to adapt to different types of staples, thereby improving the flexibility and adaptability of the pre-compression plate to a certain extent.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
