Novel surgical draw hook for hepatobiliary surgery department

Abstract

The invention discloses a novel surgical draw hook for hepatobiliary surgery department. The novel surgical draw hook comprises a fixed outer ring, a fixed inner ring and a liquid storage shell body,wherein the fixed outer ring is fixedly connected with the fixed inner ring through a connecting column; the top surface of the fixed outer ring is fixedly connected with a mini-type air pump througha fixed frame; an output end of the mini-type air pump is connected with a gas supporting rod; a guide cylinder, which is fixedly connected with the top surface of the fixed inner ring, sleeves the surface of the gas supporting rod; a draw hook is fixedly connected with the tail end of the gas supporting rod; the tail end of the draw hook is fixedly connected with the a connecting shell body; a plurality of drainage holes are formed in the inner surface of the connecting shell body; the drainage holes are communicated with a tail end of a drainage pipe; the other end of the drainage pipe is communicated with a drainage main pipe; the drainage main pipe is communicated with an output end of a liquid suction pump; the liquid suction pump is communicated with the liquid storage shell body arranged at the outer side of the fixed outer ring through a connecting pipe. The novel surgical draw hook for the hepatobiliary surgery department is simple in structure and novel in design and is convenient for a surgeon to do a surgery.

Description

technical field [0001] The invention relates to a surgical retractor, in particular to a novel surgical retractor for hepatobiliary surgery, which belongs to the technical field of medical device applications. Background technique [0002] With the continuous improvement of living standards, the level of treatment for some surgical diseases is also constantly improving. Hepatobiliary surgery mainly studies hepatocellular carcinoma, hepatic bile duct stones, post-hepatitic cirrhosis and acute liver failure caused by severe hepatitis. Major diseases of Chinese people's health; Chinese hepatobiliary surgery has formed a relatively complete theoretical and technical system in the surgical treatment of hepatocellular carcinoma, hepatolithiasis and traumatic bile duct strictures in combination with the characteristics of Chinese people's hepatobiliary diseases. [0003] At present, there are many problems in the use of surgical retractors in hepatobiliary surgery. For example, whe...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many problems in the use of surgical retractors in hepatobiliary surgery. For example, when some existing surgical retractors are used, the operation is relatively cumbersome, which increases the labor intensity of the staff when pulling the chest cavity, and affects the operation time. It may lead to the accumulation of fluid in the patient's pleural cavity, which will affect the success rate of the doctor's operation and is not convenient for the doctor to use.
