Description
Technical Field
The invention relates to the field of medical equipment, in particular to a laparoscopic quick-operation purse-string forceps.
Background
The purse-string forceps consists of a handle, a jaw, a staple and a purse-string. Purse-string forceps are used to grasp, secure and pull tissue to assist a physician in performing a surgical procedure. The purse-string forceps have the following characteristics: 1. clamping force is adjustable: the design of the purse-string forceps enables the clamping force to be adjustable, and doctors can flexibly adjust the clamping force according to the operation needs so as to ensure the safety and stability of tissues in the operation process. 2. The structure is simple: the purse-string forceps are relatively simple in structure and consist of two clamping arms and a connecting rod. This simple structure makes the purse-string forceps easy to clean and maintain, while also reducing the complexity of the procedure during surgery. Laparoscopic surgery is surgery using laparoscopes and related instruments, purse-string suturing is one of the varus sutures, and is mainly used for embedding, so that wounds are not exposed, pollution can be reduced, and healing can be promoted. In general, in surgical operation, the purse is stitched manually, but this mode is complicated and the stitching amount is not easy to control.
Purse-string forceps in the market today operate by stapling a tissue with a purse string between the staple and the tissue. The tissue to be sutured is only placed in the middle of the chuck at the front end of the purse-string forceps, the front end tissue is extruded by the handle, and the staples are sutured into the tissue. However, when performing intestinal surgery, the staples may penetrate through two layers of large intestine tissue when using the purse string forceps to suture the staples, resulting in failure of the purse string suture.
For example, the chinese patent application publication No. CN104434242B provides an end effector, a surgical instrument and a purse string forceps, wherein purse string suturing of the remaining ends of the luminal tissue is achieved by providing a first forceps arm, a second forceps arm and a suturing mechanism, but this approach easily sutures the two luminal tissues together, resulting in failure of purse string suturing.
