Inflatable type zero-damage blood vessel occlusion tractor

Abstract

The invention relates to a medical instrument, in particular to an inflatable type zero-damage blood vessel occlusion tractor which is an auxiliary operation instrument used for stopping blood and exposing operation view without damage in surgical operation. The inflatable type zero-damage blood vessel occlusion tractor comprises a blood vessel clamp pipeline comprising an upper wall and a lower wall. The upper wall is movably connected with the lower wall through a clamping groove and a lock catch which are matched with each other, an air bag is arranged on the inner wall of the upper wall, and rubber is embedded on the inner wall of the lower wall. The inflatable type zero-damage blood vessel occlusion tractor further comprises an air flow control device for controlling air amount in the air bag, and the air flow control device comprises an air inflation device, a vent pipe and an air flow controller arranged on the vent pipe. The air inflation device is a needle cylinder with a pushing handle or a hand air pump, the vent pipe is a high-temperature-resisting rubber pipe, the air flow controller is a clamp or forceps with lock catches, and the vent pipe is communicated with the air bag on the inner wall of the upper wall. The inflatable type zero-damage blood vessel occlusion tractor has the advantages of being small in size, low in weight, convenient to carry, simple and feasible in operation, strong in pertinence, and wide in practicability.

Description

technical field [0001] The invention relates to a medical device, in particular to an auxiliary surgical device for blocking blood flow without damage and exposing the surgical field of view without damage in surgical operations. Background technique [0002] In abdominal surgery, it often involves temporary blockage of blood supply to organs and limited exposure of deep surgical field, especially near blood vessels, such as liver resection or liver transplantation. [0003] At present, when temporarily blocking the blood supply of an organ, the surgeon often uses vascular clamps to clamp the blood vessel wall of the artery or vein to achieve the purpose of blocking the blood flow. Damage to the inner wall causes poor blood flow and thrombosis. [0004] In the operation of deep abdominal organs, in order to expose the surgical field near the blood vessels, the surgeon often temporarily uses surgical sutures to pull the blood vessel wall of the deep artery or vein to move th...

AI Technical Summary

Problems solved by technology

The pulling force and cutting force of the surgical suture on the blood vessel wall not only easily cause damage to the inner and outer walls of the blood vessel, aggravate the tissue adhesion in the blood vessel area, but also have the risk of cutting the blood vessel, causing deep bleeding
