surgical ligature

Abstract

The invention discloses a ligator for a surgical operation. The ligator comprises an outer barrel, an inner barrel, a driven gear, two driving gears, two gear shafts, a shell, a driving device and a heating device. The cross section of the outer barrel is in a C shape, and the shell is fixed to the side wall of the outer barrel. Sliding space and heating space are arranged in the shell. The inner barrel can advance in the outer barrel along a spiral line. A protrusion is arranged on one end face of the inner barrel, and a protrusion opening is formed in the side face of the protrusion. The sliding space of the shell and a cavity in the protrusion can be communicated through the protrusion opening. The other end of the inner barrel is fixedly connected with the driven gear. The two driving gears drive the driven gear to rotate. The basic function of blood vessel ligation is met, meanwhile, the advantages of being easy and convenient to operate, small in surgical wound, low in injury and the like are achieved, and the development demand of the future minimally invasive operation field is fully met.

Description

technical field [0001] The invention belongs to the field of clinical surgery treatment and can be used for ligation of blood vessels or tissues in the body in laparotomy and laparoscopic surgery. technical background [0002] Ligation is one of the most commonly used and basic operations in surgery. The quality and speed of ligation have an important impact on operation time, operation safety and patient's prognosis. Proficiency in the correct surgical ligation method is a prerequisite for surgeons. Traditional surgical ligation is performed manually by surgeons. With the development and popularization of endoscopic technology and the technical limitations of endoscopic technology itself, surgical ligation has gradually developed into instrument clamp closure. Ligation clips currently used for clamp closure can be roughly divided into two categories: non-absorbable and absorbable according to their different materials. However, no matter which type of ligation clip is us...

AI Technical Summary

Problems solved by technology

However, no matter which type of ligation clip is used, due to the limitations of its clamping method itself (the clamped tissue is extruded into a linear shape) and the large volume of the ligation clip itself, it has different degrees of influence on the limited surgical field of view, thus Affect the safety of surgery

In addition, since the thickness of the tissues and blood vessels that need to be clamped during surgery varies, this requires the surgeon to choose a suitable ligation clip according to the actual situation of the tissue to be ligated, which obviously increases the complexity of the surgical operation.
