Description
Technical Field
The invention belongs to the technical fields of treatment, first aid and medical treatment, and particularly relates to a semiautomatic purse-string suture device.
Background
The purse-string suture device is a medical instrument which is frequently used when performing surgery on human tissues such as intestinal tracts, soft tissues or skin surgical incisions, and has important functions in improving the working efficiency of surgeons and shortening the surgery time. In the prior art, there are two methods for performing purse string suture operations: one is manual stitching, which is time-consuming and labor-consuming and is easy to operate by mistake; another is the use of an automatic purse-string stapler. However, the existing automatic purse-string suture device is mainly used for suturing intestinal and skin incisions, and the structure of the existing automatic purse-string suture device mainly comprises a handle clamping seat and a nail bin assembly, wherein the two handle clamping seats are crossed to form a scissor-shaped structure or form a gun-shaped structure back and forth, and nails, nail pushing sheets and purse-string wires are arranged in the nail bin assembly; after the handle is clamped, nails in the nail bin are shot out, the purse string is fixed on the outer wall of the tissue, and then the purse string can be tightened to bind the purse. Chinese patent CN101756724a describes an annular pouch stapler, which comprises an annular staple cartridge, the annular staple cartridge has an outer wall and an inner wall, a plurality of staple holes are formed from the outer wall to the inner wall in a penetrating manner, each staple hole is internally provided with a staple pushing sheet and a staple, staple legs of the staple are provided with a pouch wire, the staple pushing sheet can move relative to the annular staple cartridge along the direction from the outer wall to the inner wall, and the staple can be pushed out of the annular staple cartridge and is pricked into tissues.
In the field of peritoneal dialysis catheterization, it is also necessary to suture the peritoneal tissue with a purse-string, but the above-described existing purse-string suture device is not directly applicable to purse-string suturing of the peritoneal tissue. Firstly, when the existing purse-string suture device is used for suturing the purse-string, the clamp seat of the purse-string suture device is required to be opened, the front end of the clamp seat is required to be opened sufficiently so that tissues can enter a suture zone from a notch on one side of the clamp seat without obstruction, the operation zone is required to be sufficiently large so that the opened purse-string suture device can enter the operation zone without obstruction, and therefore the clamp seat is only suitable for suturing esophagus, intestinal tracts or thicker soft tissues, and the space of peritoneal tissues is not large enough to provide enough operation zone for suturing; secondly, the peritoneal tissue is a layer of soft tissue which is thin, and the peritoneal membrane is very easy to tear when being fixed by nails; in addition, in the purse string suture process of the peritoneal tissue, the peritoneal dialysis catheter is placed in the center of the peritoneum tissue of the purse string, and the peritoneum tissue wall can be tightly attached to the peritoneal dialysis catheter by using the purse string, but if the purse string suture device in the prior art is used for suture, the purse string is not easy to pack the peritoneal dialysis catheter due to the existence of a sharp nail, and the postoperative peritoneal dialysis fluid leakage is easy to cause. Therefore, in order to simplify the procedure of purse string suture in the peritoneal operation, shorten the time for surgical purse string suture, improve the operation efficiency, and simultaneously avoid the damage to the peritoneal tissue, a novel purse string suture device needs to be developed so as to facilitate the purse string suture in the peritoneal dialysis tube placement operation field.
