[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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 are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, a stapler assembly includes a stapler locking rod 1, which uses titanium nails or stainless steel nails to connect tissues, can achieve rapid hemostasis, and the suture is tight with moderate tightness, greatly shortening the operation time, and rarely has side effects and surgical complications. The front side of the stapler locking rod 1 is fixedly provided with a stapler seat 2, and the front side of the stapler seat 2 is clamped with a stapler body 4. The staplers are arranged in a staggered manner, which can avoid bleeding on the surgical surface. At the same time, the staplers adopt a gecko claw-like design to better fix the tissue, reduce tissue flow, and ensure the surgical effect. Both ends of the stapler body 4 are connected to an embedded plate 6, and the lower side of the stapler body 4 is fixedly connected to a T-shaped bottom plate 5 for fixing the stapler body 4. The interior of the stapler seat 2 is rotatably connected to a nail anvil 3, and the nail anvil 3 adopts a flattened setting to accurately reach a narrow surgical tissue area.

[0028] Both ends of the nail magazine body 4 are slidably connected with a telescopic circular plate 8 for fixing the nail magazine body 4. A first connecting spring 10 is connected between the two telescopic circular plates 8 and the nail magazine body 4. A disc 9 is installed on one side of the two telescopic circular plates 8. Through the setting of the disc 9, the two discs 9 are compressed at the same time, and the disc 9 can squeeze the two telescopic circular plates 8 installed with the first connecting spring 10, so that the two telescopic circular plates 8 can be retracted to facilitate the release of the limit on the nail magazine body 4, so that different nail magazines can be quickly replaced to meet the needs of various surgeries. It is easy to use. The rear side of the nail magazine body 4 is fixedly installed with two symmetrically arranged plug posts 7, and the interior of the nail magazine seat 2 is installed with two symmetrically arranged cross bars 11. The cross bars 11 and the embedded plate 6 can be used to further fix the nail magazine. A T-slot 18 is provided on the front side of the anastomosis device locking rod 1, and the T-shaped bottom plate 5 is located inside the T-slot 18.

[0029] Grooves 12 are provided on both sides of the stapler locking rod 1, and two symmetrically arranged elastic snap plates 13 are connected to the inside of the grooves 12. The elastic snap plates 13 are located inside the grooves 12. Through the setting of the elastic snap plates 13, pressing the two elastic snap plates 13 can retract the inside of the grooves 12 so as to remove the stapler locking rod 1.

[0030] Both ends of the stapler locking rod 1 are slidably connected with positioning protrusions 14, and the lower sides of the two positioning protrusions 14 are fixedly connected with connecting plates 16. A second connecting spring 15 is connected between the two positioning protrusions 14 and the stapler locking rod 1. Through the setting of the positioning protrusions 14, pressing the two connecting plates 16 can drive the two elastic positioning protrusions 14 to retract, so as to remove the stapler locking rod 1.

[0031] Two symmetrically arranged slots 17 are provided inside the stapler locking rod 1 , and the slots 17 are adapted to the insertion post 7 . The rear side of the insertion post 7 is engaged with the interior of the stapler locking rod 1 through the slots 17 .

[0032] Two circular grooves 19 are provided on the inner side surface of the nail magazine seat 2 , and the circular grooves 19 are adapted to the telescopic circular plate 8 . One side of the telescopic circular plate 8 is snap-connected to the inner side surface of the nail magazine seat 2 through the circular grooves 19 .

[0033] A circular hole 20 is formed on the rear side of the two embedded plates 6 . The circular hole 20 is adapted to fit the cross bar 11 . The front side of the cross bar 11 is slidably engaged with the rear side of the embedded plates 6 through the circular hole 20 .

[0034] The working principle of the anastomosis device provided by the present invention is as follows:

[0035] The staple cartridge body 4 is first clamped to the interior of the staple cartridge seat 2, and then the two telescopic circular plates 8 installed with the first connecting spring 10 are squeezed. The elastic force of the first connecting spring 10 allows the two telescopic circular plates 8 to be retracted into the interior of the staple cartridge body 4, so that the T-shaped bottom plate 5, the embedded plate 6 and the plug post 7 can further position the position of the staple cartridge body 4. Then, as the staple cartridge body 4 is clamped, the two elastic telescopic circular plates 8 can automatically extend and clamp to the interior of the circular groove 19, so as to firmly position the staple cartridge in the staple cartridge seat 2. Subsequently, the cross bar 11 can play the role of limiting the embedded plate 6, so as to reinforce the installation of the staple cartridge body 4, so that the staple cartridge on the stapler assembly can be fixed more firmly, thereby improving the stability of the stapler assembly during use and preventing the staple cartridge from becoming loose and affecting its use.

[0036] By pressing the connecting plate 16 and the elastic snap plate 13, the positioning protrusion 14 installed with the second connecting spring 15 and the elastic snap plate 13 can be compressed, so that the stapler locking rod 1 can be inserted into the interior of the stapler. In this way, the stapler locking rod 1 can be easily assembled by snapping, so that the stapler locking rod 1 can be easily loaded and unloaded, thereby improving the assembly efficiency of the stapler assembly.
