Tube flow control device for laparoscopic surgery

Abstract

The invention discloses a tube flow control device for laparoscopic surgery, comprising: a handle having an inner end adapted to extend into the abdominal cavity and an outer end adapted to remain outside the abdominal cavity; the middle rod that is connected with the inner end; a working rod, wherein the two ends of the working rod are the near end and the far end respectively, the near end is connected with the middle rod, the working rod can be switched between a straight rod shape and a lantern ring shape, the area defined by bending of the lantern ring-shaped working rod is an in-ring space, the working rod surrounds a pipe body of the visceral organ through the in-ring space when the working rod is in the lantern ring shape, and the working rod is constructed to have the tendency of deforming towards the lantern ring shape; the traction rope that is located on the middle rod, one end of the traction rope is connected to the far end along the side, deviating from the in-ring space, of the working rod, the other end of the traction rope extends to the handle, and the traction rope drives the working rod to deform towards the straight rod when being pulled towards the handle. The tube flow control device is convenient to use and capable of safely and effectively controlling flowing of liquid in the visceral organ pipe body.

Description

technical field [0001] The invention relates to the technical field of medical treatment and medical equipment, in particular to a tube flow control device for laparoscopic surgery. Background technique [0002] With the development of minimally invasive surgical techniques and instruments, more and more laparoscopic techniques are used in liver operations represented by partial hepatectomy. The liver is an organ with a very rich blood supply. Hemorrhage during liver-related operations will hinder the operation and pose a threat to the safety of the operation. In order to be able to perform surgery under a clear view, the hepatic hilum is often blocked during surgery to block the blood flow into the liver, so as to reduce surgical bleeding. Unfortunately, there is still a lack of devices that can effectively control blood flow into the liver in laparoscopic surgery. Existing methods to control blood flow into the liver are mostly realized by blocking bands, etc. However, t...

AI Technical Summary

Problems solved by technology

Existing methods to control blood flow into the liver are mostly achieved by blocking bands, etc. However, the rear of the hepatic hilum is an invisible area, and the operation of delivering the blocking band through surgical forceps has the risk of inconvenient operation and important structures of the hepatic hilum
