Suspension control of hepatic blood flow occlusion device under endoscope

Abstract

The invention discloses a suspension control hepatic blood flow blocking device under an endoscope, which comprises a blood flow blocking device, a protection structure, a sealing film, an inner core of the blood flow blocking device and a blocking belt, wherein the blood flow blocking device is in a hard cylindrical structure of which the two ends are opened; the protection structure is arranged on the front end of the blood flow blocking device; the sealing film is arranged on the rear end of the blood flow blocking device; the sealing film is used for covering the rear opening of the blood flow blocking device; the sealing film is provided with an opening; the inner core of the blood flow blocking device is arranged in the inner cavity of the cylindrical structure of the blood flow blocking device; the front end of the inner core of the blood flow blocking device is provided with a hooking groove; the blocking belt is arranged in the hooking groove. The suspension control hepatic blood flow blocking device under the endoscope, which is disclosed by the invention, has the advantages of simple structure and convenience in use and operation, whether the blood flow of a vessel is blocked or not can be controlled under the endoscope environment, the vessel suspension degree can be controlled by regulating the position of the blood flow blocking device, and the operation process and the effect of the suspension control hepatic blood flow blocking device under the endoscope are almost consistent with those of vessel blocking under the laparotomy. Necessary equipment support is provided for having a relevant operation conveniently and safely under the endoscope by blocking the blood flow of the vessel.

Description

technical field [0001] The invention relates to the technical field of medical devices, and is a device capable of blocking liver blood vessels under an endoscopic environment with simple structure and convenient operation. Background technique [0002] The requirements for minimally invasive medical operations are increasing day by day. As a kind of minimally invasive medical treatment, laparoscopy has played an increasingly important role in the surgical treatment of abdominal cavity, uterine cavity and other human cavities. It is very important to control hepatic vascular bleeding when resection of rich blood vessels under laparoscopy. Usually, laparoscopic surgery with large amount of bleeding will be avoided in clinical operations. The failure to effectively control hepatic vascular bleeding directly hinders A large number of operations cannot be performed laparoscopically. For example, during partial liver resection, it is usually necessary to block the blood flow int...

Problems solved by technology

However, this method is difficult to place the elastic blocking band at the target position during laparoscopic surgery. Even if it is placed in place, it cannot conveniently block the target blood flow immediately. As a result, once there is a lot of bleeding, it can only be converted to laparotomy during the operation. Follow-up
