Description

Purse-string forceps

Technical Field

The utility model belongs to the technical field of medical instrument equipment, concretely relates to purse-string forceps.

Background

The purse-string forceps is a common surgical instrument for gastrointestinal surgery, and is commonly used for purse-string suturing of stomach, esophagus, intestinal canal and the like. The purse-string forceps generally comprise a jaw, a connecting rod and a forceps handle, during the operation process of thoracic surgery, gastrointestinal surgery and the like, the jaw is used for clamping tissues firstly, then the notch is locked, the tissues can be naturally clamped, and a part of tissues are squeezed into the gap of the notch. Then the purse-string needle is inserted into the notch, and after the notch is loosened, the suture is pulled up to be sutured in a purse-string way. The purse-string forceps are used for purse-string suturing organs such as stomach, esophagus, intestinal canal and the like, so that time and labor can be saved when stomach cancer, esophageal cancer and rectal cancer are anastomosed, the operation time of the operation is shortened, and postoperative recovery of a cancer patient is facilitated; the purse-string forceps are generally disposable, and some purse-string forceps have complex structures and low cost performance; some purse-string forceps have poor flexibility and are inconvenient to sew deep in a patient, or the purse-string forceps have poor using effect and cannot effectively clamp a purse-string needle into a target affected part.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the Chinese patent document discloses a surgical purse-string forceps [201520886394.5], which comprises a jaw, a connecting rod and a forceps handle, wherein the jaw is internally provided with forceps teeth, and the forceps teeth are provided with rivets. The upper and lower teeth of the forceps teeth are matched with each other to form an arc-shaped groove for clamping tissue organs, 9 forceps teeth are arranged in the forceps jaws from top to bottom, and a rivet is arranged between every two adjacent forceps teeth in the middle section of the forceps jaws.

Above-mentioned scheme has solved the problem that the pocket pincers structure is complicated, inconvenient struts the chamber to a certain extent, but this scheme still has a great deal of not enough, for example, because its pincers mouth adopts traditional 9 pincers tooth types, its suture effect remains to be strengthened, and the pincers mouth is comparatively sharp-pointed, easily damages the chamber when strutting the chamber.
