Example one

As shown in fig. 1 to 15, a staple suturing device according to the present embodiment, which is mainly used for suturing the digestive tract, includes: a guide lumen tube 210, a clamp 410, an endoscope 350, a first operating member 510, a second operating member 520 and a staple stapler.

The guide lumen tube 210 has a first guide lumen 211 and a third guide lumen 215, and a first push-pull member 310 is disposed in the first guide lumen 211. in this embodiment, the first push-pull member 310 is made of a guide steel wire having a certain elasticity and rigidity, an endoscope 350 is disposed in the third guide lumen 215, a fourth guide lumen 351 is disposed in the endoscope 350, and a control cable 530 is disposed in the fourth guide lumen 351. The guide lumen 210 is flexible, bendable and not easily deformable, and may be integrally formed of a highly elastic material, or a tube with an embedded spring, or other tube members meeting the requirement of elastic performance. The guiding cavity plays a role in guiding and limiting, and the arrangement of the guiding cavity enables the first push-pull piece 310 to be bent adaptively in a bending state, so that the push-pull force is effectively transmitted.

The front end of the endoscope 350 is inserted into the fixing insertion hole 113 of the base body 110 of the nail-shaped stapler, and can be connected with the base body 110 of the nail-shaped stapler through interference fit or other connectors, and other cavities can be arranged in the endoscope 350 according to requirements, such as transmission of images, or transportation of gas or liquid, and the like. The clamp 410 can be passed through the working channel of the endoscope 350, out of the stationary receptacle 113 of the housing 110 of the staple stapler, and the clamp 410 can be controlled by the steering cable 530.

It should be noted that:

in the present invention, when the first operating element 510 drives the first colliding element 120 to translate, the transmission structure is not limited to the foregoing manner, and in the following embodiments, a possible transmission manner will be described, it can be understood that other similar structures can also be used to implement translation of the first colliding element 120 relative to the second colliding element 130, and suture the human tissue by the suture nail 600, which is within the protection scope of the present application.

Please refer to fig. 14 and 15, in this embodiment, the suturing nail 600 is approximately n-shaped, and includes a nail plate 620 and two nail bodies 610 installed at one side of the nail plate 620, the nail tips 611 of the two nail bodies 610 face forward, when suturing, the first striker 120 drives the suturing nail 600 to collide with the second striker 130, and bends the nail body 610 of the suturing nail 600, and the nail tip 611 bends and returns to the nail plate 620, so that the nail plate 620 can block the nail tip 611 to prevent the nail tip 611 from damaging the human tissue again. In order to facilitate the installation of the suturing nail 600 and avoid the deviation, deflection or falling of the suturing nail 600 in the suturing process, the nail fixing piece 140 is arranged on the nail piece installation position 125, the nail fixing piece 140 is elastic, the size of the nail fixing piece is slightly smaller than that of the suturing nail 600, furthermore, the nail fixing piece 140 is similar to a C shape and comprises a connecting edge 141 and two limiting edges 142, the two limiting edges 142 are positioned at two ends of the connecting edge 141 and integrally formed, two sides of the suturing nail 600 are limited by the two limiting edges 142, and the suturing nail 600 is prevented from falling off. After the suturing is performed, due to the elasticity of the two limiting edges 142, the limited suturing nail 600 can break through the limitation of the limiting edges 142 under the action of external force, so that the suturing nail 600 is separated from the nail fixing piece 140.
