Surgical retractor for hepatobiliary and pancreatic surgery

Abstract

The invention relates to the technical field of medical apparatus and instruments, and discloses a hepatobiliary and pancreatic surgery operation drag hook which comprises a circular ring, telescopic rods and a mounting seat, the bottom of the circular ring is symmetrically and rotatably connected with the telescopic rods through a rotating shaft, the bottom ends of the telescopic rods are fixedly connected with the mounting seat, and a first annular groove is formed in the upper surface of the circular ring; second annular grooves are integrally formed in the two sides of the inner side wall of the first annular groove, two sliding blocks are slidably connected to the interior of the first annular groove, and penetrating type bayonets are formed in the left sides of the sliding blocks; through the arrangement of a circular ring, a first annular groove, a second annular groove, a sliding block, a clamping opening, a cavity, an annular strip, a notch, a conical inserting opening, an abutting strip, a first spring and a connecting block, the sliding block is conveniently disassembled and installed on the inner side of the first annular groove and can slide along the first annular groove, and then the number of the installed L-shaped drag hooks and the pulling position can be controlled; and a better operation effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a surgical retractor for hepatobiliary and pancreatic surgery. Background technique [0002] With the continuous improvement of living standards, the treatment level of some surgical diseases is also constantly improving. Hepatobiliary surgery mainly studies hepatocellular carcinoma, hepatolithiasis, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis, which are serious threats. A major disease of Chinese people's health; China's hepatobiliary surgery has formed a relatively complete theoretical and technical system in the surgical treatment of hepatocellular carcinoma, hepatolithiasis, and traumatic bile duct strictures based on the characteristics of Chinese people's hepatobiliary diseases. To stretch the surgical wound to fully expose the field of view suitable for surgery, it is a commonly used instrument in medical surgery. [0003] The hepat...

Problems solved by technology

[0003] The hepatobiliary pancreas is an important organ of the human body located on both sides of the upper abdomen of the human body. During the operation, an operation on one side is required for clinical surgical treatment. At present, the retractors used in the hepatobiliary and pancreatic surgery are held by doctors and nurses or use the retractors to droop naturally for wound traction. The former requires many people. Cooperate, medical staff needs a lot, hold for a long time, the labor intensity is high, and the operation space is small. Often the position is relatively fixed, there is not enough space for the doctor to operate, and the retractor will also cause a certain shadow when it is working, which is not conducive to the operation. Therefore, we propose a surgical retractor for hepatobiliary and pancreatic surgery.
