Problems solved by technology

The first two are commonly used methods. The opening angle of the endoscopic metal clip and the firmness of the closure are limited, and are generally used for the closure of small-sized defects; the purse-string suture of the nylon rope combined with the metal clip can repair larger-sized perforations, but it is flexible. The performance and firmness are not good, and the operation is more complicated
With the development of minimally invasive technology under flexible endoscope, the above methods of defect repair and suturing have been difficult to meet the needs of surgery

Embodiment 1

[0081] Such as Figure 1 to Figure 13 As shown, the plug-shaped suturing device, the plug-shaped suturing device described in this embodiment is mainly used for suturing the digestive tract, and it includes: a guide lumen 210, a clamp 410, an endoscope 350, a first operating member 510, a second The operating member 520, the third operating member 530 and the plug-shaped stapler.

[0082] The guide lumen tube 210 has a first guide cavity 211, a second guide cavity 212, and a third guide cavity 213, and a first push-pull member 312 is arranged in the second guide cavity 212. In this embodiment, the first push-pull member 312 adopts It is made of guide steel wire with certain elasticity and rigidity, and its function will be described later. An endoscope 350 is built in the third guide cavity 213, an endoscope cavity 351 is arranged in the endoscope cavity 350, and a control tube is arranged in the endoscope cavity 351. Cable 313. The guide lumen 210 is elastic, bendable and n...

Embodiment 2

[0107] Such as Figure 14 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, a closed guide groove 1231 is provided on the first collision member 120, and the closed guide groove 1231 is connected with the second The pin shaft 332 is in sliding fit. The principle is the same as that of the first embodiment, and will not be repeated here.

Embodiment 3

[0109] Such as Figure 15 , Figure 16 As shown, in this embodiment, both ends of the first transmission member 163 are bar hole structures, that is, the force application part 166 and the force transmission part 167 of the first transmission member 163 are respectively the first chute, and the second Two chute, the front end of the first push-pull member 312 is provided with a fifth pin shaft 335, the fifth pin shaft 335 is slidingly matched with the first chute, and a second pin shaft 332 is provided on the first collision member 120 , the second pin shaft 332 cooperates with the second sliding groove.

Abstract

The invention discloses a bolt-shaped suturing instrument, a bolt-shaped suturing mechanism, a bolt-shaped suturing device and an endoscope suturing method. The bolt-shaped suturing instrument comprises a base body and a first collision piece, wherein the base body is provided with a first linear guide part; the first collision piece is provided with a second linear guide part; the first collision piece is movably installed on the base body; in addition, a first linear guide part is in sliding fit with the second linear guide part; a second collision piece is further arranged on the base body; the first collision piece is opposite to the second collision piece; one of the first collision piece and the second collision piece is provided with a conveying pipeline for placing a suturing part, and the opposite side surface of the other one is provided with a bolt piece suturing part; a pipeline tip is arranged at the front end of the conveying pipeline; a hollow conveying channel is arranged in the conveying pipeline; and a conveying control piece is arranged in the conveying channel. The bolt-shaped suturing instrument can be effectively suitable for the requirement of the endoscopic minimally invasive technology, and the suturing effect is more ideal.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a plug-shaped suturing device, a plug-shaped suturing mechanism, a plug-shaped suturing device and an endoscopic suturing method. Background technique [0002] Gastrointestinal defect, especially gastrointestinal perforation, is a common problem in minimally invasive surgery under flexible endoscope. At present, endoscopic suture methods include endoscopic metal clip closure, nylon rope combined with endoscopic metal clip purse suture, and some high-end suture devices reported abroad. The first two are commonly used methods. The opening angle of the endoscopic metal clip and the firmness of the closure are limited, and are generally used for the closure of small-sized defects; the purse-string suture of the nylon rope combined with the metal clip can repair larger-sized perforations, but it is flexible. The performance and firmness are not good, and the operation is mo...
