Automatic purse string clamp

Abstract

The invention provides automatic purse string clamp which comprises a tool body and further comprises a swing arm shaft, a cam, a suture needle, a movable slide block and a line clamping slide block. The swing arm shaft and the cam are both connected with a central shaft of the tool body, the suture needle is connected with the swing arm shaft, the movable slide block and the line clamping slide block are both arranged on the tool body, the movable slide block is in slide fit with the tool body and can drive the line clamping slide block to move downwards, a suture needle hole is formed in the line clamping slide block, a suture sleeve groove is formed in the inner side of the suture needle hole, a suture sleeve is arranged at the tail end of a suture of the automatic purse string clamp, and the suture sleeve is arranged in the suture sleeve groove, and a notch is formed above the suture needle hole. The automatic purse string clamp can enable the suture to penetrate tissues to finish operation without using a suture nail, so that the phenomenon that the suture nail falls down is avoided, and accordingly the automatic purse string clamp enables the operation to be finished safely and reliably.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an automatic purse forceps. Background technique [0002] In the surgical operation of medical science, since the first staple product was invented in the 1960s, the medical stapler has become an indispensable medical device to assist in the process of incision suturing. With the development of medicine and product research and development, more and more multifunctional staple products are used in clinical practice. The scope of application has been involved in various fields such as gastrointestinal surgery, hepatobiliary surgery, thoracic surgery, urology, obstetrics and gynecology, and has become one of the indispensable tools for doctors. For patients, it has many advantages such as less blood loss during operation, less operation time, using instruments instead of manual operation to reduce errors caused by manual operation, avoiding infection, and quick recover...

AI Technical Summary

Problems solved by technology

This instrument has great disadvantages for surgical sites with limited positions such as rectal resection or esophagectomy: first, the suture can only be pulled along the transverse plane of the organ tissue, which requires a suitable operating space, otherwise it is easy to The oblique force causes the staples to separate from the tissue, resulting in the failure of the purse bag, which may cause the staples to fall into the human body. Due to the limited position and the small size of the staples, it is not easy to find the fallen staples, which may eventually cause the staples to remain in the body. In the human body, it may cause life-threatening to the patient, and the safety of the automatic purse forceps is unreliable
