[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] An embodiment of the present application discloses a welding jig for an anastomosis device bracket.

[0033] Reference Figure 1 and Figure 2 A welding jig for an anastomosis device bracket includes a base 1, a cover plate 2, and a locking assembly 3 for locking the base 1 and the cover plate 2 in position.

[0034] The base 1 has a welding groove 11 on one side and a welding hole 12 on the other side. The welding hole 12 connects to the bottom of the welding groove 11. An auxiliary pressure block 4 is installed in the welding groove 11. The cover plate 2 abuts against the base 1 and blocks the welding groove 11. The cover plate 2 is provided with an elastic abutment 5, which abuts against the auxiliary pressure block 4.

[0035] Place the suture needle and the stapler bracket in the welding groove 11, and align the welding point with the welding hole 12, then use the auxiliary pressure block 4 to press the suture needle and the stapler bracket, then cover the opening of the welding groove 11 with the cover plate 2, so that the elastic abutment block 34 abuts against the auxiliary pressure block 4, and then use the locking assembly 3 to lock the cover plate 2 and the base 1, so that the cover plate 2 fits on the base 1, so that the elastic abutment block 34 abuts against the auxiliary pressure block 4, and then the auxiliary pressure block 4 presses the suture needle and the stapler bracket, and finally weld the welding point of the suture needle and the stapler bracket through the welding hole 12.

[0036] By utilizing the cooperation of the base 1, the cover plate 2, the auxiliary pressure block 4, the elastic abutment 5 and the locking assembly 3, the suture needle and the anastomosis device bracket are fixed at the bottom of the welding groove 11, thereby facilitating welding between the suture needle and the anastomosis device bracket located in the welding groove 11 through the welding hole 12.

[0037] Reference Figure 2 and Figure 3The locking assembly 3 includes a mounting base 31 symmetrically arranged about the cover plate 2, and an abutment rod 32 and a connecting rod 33 are hinged on the mounting base 31. An abutment block 34 is fixedly connected to the end of the abutment rod 32 away from the mounting base 31, and a handle 35 is hinged on the connecting rod 33. The end of the abutment rod 32 close to the mounting base 31 is hinged to the handle 35, so that when the handle 35 is rotated, the abutment block 34 is controlled by the abutment rod 32 to press against the cover plate 2.

[0038] When the base 1 and the cover 2 need to be locked, the handle 35 is rotated downward. At this time, the side of the handle 35 close to the connecting rod 33 is rotated upward. At this time, the end of the abutting rod 32 close to the handle 35 is rotated upward, so that the end of the abutting rod 32 close to the abutting block 34 rotates downward with the abutting block 34, so that the abutting block 34 is pressed against the cover 2, so that the cover 2 fits the base 1. At the same time, due to the action of the connecting rod 33, the handle 35 can be locked by itself when it is rotated downward to the extreme position.

[0039] When the lock between the base 1 and the cover 2 needs to be released, the handle 35 is rotated upward, and the side of the handle 35 close to the connecting rod 33 is rotated downward. At this time, the end of the abutment rod 32 close to the handle 35 is rotated downward, so that the end of the abutment rod 32 close to the abutment block 34 rotates upward with the abutment block 34, thereby releasing the lock on the cover 2, allowing the cover 2 to freely detach from the base 1.

[0040] In an optional embodiment, a rubber sleeve 36 is provided on the side of the handle 35 away from the mounting base 31, and the surface area of ​​the rubber sleeve 36 on the side away from the handle 35 is larger than the surface area on the side close to the handle 35. The provision of the rubber sleeve 36 not only increases the lever arm for facilitating rotation of the handle 35, but also the larger surface area of ​​the rubber sleeve 36 makes it easier to control the handle 35.

[0041] There are multiple welding grooves 11 on the base 1, and in this embodiment, there are 10 welding grooves 11, which are symmetrically arranged on both sides of the abutment rod 32, that is, there are 5 welding grooves 11 evenly arranged on one side of the abutment rod 32, and there are 5 welding grooves 11 evenly arranged on the other side. The arrangement of multiple welding grooves 11 facilitates the installation of multiple welding points of suture needles and anastomosis brackets, so that the welding points of multiple suture needles and anastomosis brackets can be welded after locking them once.

[0042] There are multiple cover plates 2. In this embodiment, there are two cover plates 2, and the two cover plates 2 are evenly distributed on both sides of the abutment rod 32. The cover plates 2 are evenly distributed on both sides of the abutment rod 32, so that when the abutment rod 32 locks the cover plate 2, the cover plate 2 is subjected to more uniform force.

[0043] The elastic abutment member 5 includes a spring 51 and a protrusion 52. A mounting groove 21 is defined on the cover plate 2. The protrusion 52 is slidably connected within the mounting groove 21. One end of the spring 51 is fixedly connected to the bottom of the mounting groove 21, and the other end is fixedly connected to the protrusion 52. The spring 51 is used to drive the protrusion 52 to slide in a direction away from the bottom of the mounting groove 21, so that the protrusion 52 passes through the mounting groove 21. The spring 51 drives the protrusion 52 to pass through the mounting groove 21, so that when the cover plate 2 abuts against the base 1, the protrusion 52 can further press against the auxiliary pressure block 4, causing the auxiliary pressure block 4 to press the suture needle and the anastomosis device holder tightly.

[0044] Reference Figure 4 and 5 The cover plate 2 is fixedly connected to the side close to the base 1 with an abutting ear 22, and when the cover plate 2 is attached to the base 1, one side of the abutting ear 22 abuts against the edge of the auxiliary pressing block 4. The setting of the abutting ear 22 limits the position of the auxiliary pressing block 4, preventing the position of the auxiliary pressing block 4 from shifting when the cover plate 2 is pressed against the base 1.

[0045] The cross-sectional area of ​​the welding hole 12 gradually increases as it moves away from the welding groove 11 , which not only facilitates welding through the welding hole 12 but also makes welding more precise.

[0046] Several positioning posts 6 are fixedly connected to the base 1, and several positioning holes 7 are formed in the cover 2. In this embodiment, two positioning posts 6 are provided, located on either side of the welding groove 11, and the positioning posts 6 are inserted into the positioning holes 7 one by one. The positioning posts 6 and the positioning holes 7 cooperate to locate the fitting position between the base 1 and the cover 2, thereby facilitating the contact of the protrusion 52 with the auxiliary pressure block 4.

[0047] Several auxiliary columns 8 are fixedly connected to the base 1, and several auxiliary holes 9 are formed in the cover plate 2. In this embodiment, three auxiliary columns 8 are provided. The height of the auxiliary columns 8 is lower than that of the positioning columns 6, and the diameter of the auxiliary columns 8 is smaller than that of the positioning columns 6. The auxiliary columns 8 and the auxiliary holes 9 cooperate to further position the base 1 and the cover plate 2.

[0048] Compared with the prior art, during use, the present invention places the suture needle and the stapler bracket in the welding groove 11, and aligns the welding point with the welding hole 12, and then uses the auxiliary pressure block 4 to press the suture needle and the stapler bracket, and then covers the opening of the welding groove 11 with the cover plate 2, so that the elastic abutment block 34 abuts against the auxiliary pressure block 4, and then uses the locking assembly 3 to lock the cover plate 2 and the base 1, so that the cover plate 2 fits on the base 1, so that the elastic abutment block 34 abuts against the auxiliary pressure block 4, and then the auxiliary pressure block 4 presses the suture needle and the stapler bracket, and finally welds the welding point of the suture needle and the stapler bracket through the welding hole 12.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
