Circular purse-string forceps capable of automatically beating purse-strings

Abstract

The invention relates to circular purse-string forceps capable of automatically beating purse-strings. The forceps comprise a forceps body, a suture needle assembly, a suture needle driving device and a safety device, wherein an annular suture needle chute is arranged in the head of the forceps body; the suture needle assembly is installed in the annular suture needle chute in a slideable manner; the safety device is installed at the tail end of the forceps body and comprises a safety knob, a safety shaft and a locking block; the safety shaft is fixedly connected with the safety knob; the locking block is fixed on the safety shaft; the suture needle driving device is installed in the forceps body in a rotatable manner; the head of the suture needle driving device drives the suture needle assembly to move around the annular suture needle chute; and a clamp slot corresponding to the locking block of the safety device is arranged at the tail of the suture needle driving device. The circular purse-string forceps can ensure a defined amount of tissues on the purse-strings, and can automatically, conveniently and reliably beat the purse-strings.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a circular purse pliers capable of automatically making a purse. Background technique [0002] In surgical operations, since the invention of the first staple product in the 1960s, medical staplers have become an indispensable medical device in the process of assisting incision suturing. [0003] With the development of medicine and the research and development of medical device products, more and more staple products are being used clinically. The scope of application of this type of product has involved gastrointestinal surgery, hepatobiliary surgery, thoracic surgery, urology, obstetrics and gynecology, and has become one of the indispensable tools for doctors. For patients, the application of such tools has the advantages of less intraoperative bleeding and shorter operation time, and the use of instruments instead of manual work can reduce errors and infections caused by ...

AI Technical Summary

Problems solved by technology

This instrument has great disadvantages for rectal resection or esophagectomy and other limited surgical sites: firstly, the purse string can only be pulled along the transverse section of organ tissue, which requires a suitable operating space, otherwise it is easy The oblique force causes the staples to separate from the tissue, resulting in the failure of the purse bag. For the part with limited position, it is impossible to have a suitable operating space, so the risk of surgery in this kind of part is extremely high; Excessive pulling force 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 human body, which may pose a life-threatening threat to the patient.
