Expansion device for surgical incision for hepatobiliary surgery department

Abstract

The invention relates to the field of medical instruments, in particular to an expansion device for a surgical incision for the hepatobiliary surgery department. The expansion device comprises a top seat and an air bag assembly arranged below the top seat and used for supporting a surgical incision. The bottom of the top seat is connected with a bottom plate capable of moving up and down along the circumferential direction. A plurality of stop levers used for limiting the air bag assembly are installed between the bottom plate and the bottom of the top seat, the air bag assembly is arranged above the bottom plate in a sleeving mode, and the multiple stop levers are arranged in the air bag assembly in a sleeved mode. When the air bag assembly is stuffed into a surgical incision, the air bag assembly is filled with air, the size of the air bag assembly is increased, the inner wall of the surgical incision is gradually expanded, and then medical staff can smoothly check the condition of the focus inside the body of a patient through the top seat and the inner cavity of the air bag assembly. The body tissue at the bottom end in the bottom of the surgical incision cannot shield the focus.

Description

technical field [0001] The invention relates to an expansion device, in particular to an expansion device used for hepatobiliary surgery incision, and belongs to the field of medical devices. Background technique [0002] Hepatobiliary surgery mainly studies major diseases that seriously threaten the health of Chinese people, such as hepatocellular carcinoma, hepatolithiasis, post-hepatitic cirrhosis and acute liver failure caused by severe hepatitis. The operation of hepatobiliary surgery disease is generally inside the patient's body. After the surgical incision is formed, in order to enlarge the size of the incision and maintain a good observation environment, an expansion device is often used to expand the surgical incision. [0003] But the expansion device used in the incision of existing hepatobiliary surgery is often a harder material, which is easy to cause damage to the patient's body during expansion, and easily causes tearing of the incision. The inability to ma...

Problems solved by technology

[0003] However, the expansion device used in the incision of the existing hepatobiliary surgery is often made of relatively hard materials, which is easy to cause damage to the patient's body during expansion, and is easy to cause tearing of the incision

Failure to make timely adjustments to complex situations during surgery may easily lead to medical staff not being able to check the internal lesions in a timely manner, affecting the speed of surgery and resulting in a decrease in work efficiency during surgery
