specific Embodiment 1

[0041] Combine below Figure 1 to Figure 6 As shown, the embodiment of the present invention provides a stapler with flexible and firm nails, including a stapler main body 1 and a staple cartridge assembly 2, and the stapler main body 1 and the staple cartridge assembly 2 are detachably connected, and the staple cartridge The side of the assembly 2 is provided with a safety structure 17 , and the tail end of the main body 1 of the stapler is provided with a knob 9 , and the safety structure 17 is controlled by the knob 9 .

[0042] Specifically, the staple cartridge assembly 2 includes a locking member 10 detachably connected to the main body of the stapler 1. A connecting rod 11 is fixed to the end of the locking member 10, and the connecting rod 11 is hollow inside. One end is fixed with a movable structure 12 , and the end of the movable structure 12 away from the connecting rod 11 is fixed with a staple cartridge body 13 .

[0043] Specifically, the staple cartridge body ...

specific Embodiment 2

[0051] A curved portion 21 may be provided between the first groove 19 and the second groove 20 of the titanium nail 18 , and the shape of the curved portion 21 is S-like.

[0052] against Figure 7 The working principle of the specific embodiment 2:

[0053] In this embodiment, the titanium nail 18 of this product can be replaced with the above-mentioned technical solution, and the S-shaped bending part 21 increases the contact area between the titanium nail 18 and the tissue after bending, and the titanium nail 18 is changed from the original The two-dimensional to three-dimensional form, from the original line contact to the current surface contact, thereby enhancing the stability of the titanium nail 18 nailed into the tissue, preventing the titanium nail 18 from loosening after suturing, and giving the patient recovery after surgery. Here comes the guarantee.

specific Embodiment 3

[0055] Both the first groove 19 and the second groove 20 of the titanium nail 18 are provided with reinforcements 22, and the reinforcements 22 are made of 65 manganese.

[0056] against Figure 7 The working principle of the specific embodiment 3:

[0057] In this embodiment, the titanium nail 18 of this product can be replaced with the above-mentioned technical scheme, and the bending part of the titanium nail 18 is reinforced with 65 manganese, and 65 manganese has the advantages of high strength, good flexibility and plasticity; and the same Under the condition of surface state and complete hardening, the fatigue limit of 65 manganese is equivalent to that of the multicolored alloy spring, and has relatively good metal properties, which can ensure the stability of the titanium nail 18 after suturing.

Abstract

The invention discloses an anastomat with an easy-to-bend firm nail, and belongs to the technical field of endoscopic cutting anastomats. The anastomat comprises an anastomat body and a nail bin assembly, the anastomat body and the nail bin assembly are detachably connected, a safety structure is arranged on the side face of the nail bin assembly in a penetrating mode, and a rotary knob is arranged at the tail end of the anastomat body; and the safety structure is controlled by a knob. By the adoption of the safety structure, when tissue of a patient is cut and sutured, the nail bin assembly is not prone to loosening after clamping the tissue, the tissue loosening situation is not prone to occurring, and the difficulty in the suturing process is reduced. A pulling rope in the safety assembly sequentially passes through the nail bin assembly and the anastomat, when the knob is rotated, the pulling rope can be loosened, a sliding rod slides under the tension effect of a compression spring, a pressing plate in the nail bin assembly is limited and fixed, the pressing plate can be tightly attached to the surface of to-be-sutured tissue, and the tissue below the pressing plate is not prone to slipping off.

Description

technical field [0001] The invention relates to the technical field of endoscopic cutting staplers, in particular to a stapler with bendable and firm nails. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. Staplers can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, vascular staplers, hernia Stapler, lung cutting stapler, etc. Because of its safety, reliability, convenience and quickness, it has been widely used and promoted in recent years. Suture titanium nails play a very important role as a key part of the stapler, and have very strict requirements on its material, shape and size, because of its small size and precise size requirements, and the mouth of the titanium nail must be sharp And sharp...
