Retractor for hepatobiliary surgery

Abstract

The invention discloses a hepatobiliary surgical operation drag hook which comprises a fixing frame, an installation ring is arranged in the middle of the fixing frame, and the operation view is exposed in the installation ring through the installation ring. Two oppositely-arranged mounting frames are arranged on the mounting ring, adjusting mechanisms are arranged on the mounting frames, a plurality of hook pieces arranged side by side are connected to the adjusting mechanisms, the adjusting mechanisms are used for adjusting the distance between the hook pieces and the included angle between the hook pieces, and fixing rods are further arranged on the mounting frames. A plurality of winches corresponding to the hooks are arranged at the end of the fixing rod, and steel wires connected with the corresponding hooks are wound on the winches. When the winch rotates, the hook piece pulls the surgical incision open to expose the surgical field. The surgical retractor for the hepatobiliary surgery is ingenious in structural design and convenient to use, and the surgical efficiency is improved.

Description

technical field [0001] The invention relates to a drag hook for hepatobiliary surgery, belonging to the technical field of hepatobiliary surgery instruments. 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] Surgical treatment is one of the main treatment methods in hepatobiliary surgery. When performing an operation that requires surgery, the doctor needs to use a surg...

AI Technical Summary

Problems solved by technology

[0003] Surgical treatment is one of the main treatment methods in hepatobiliary surgery. When performing an operation that requires surgery, the doctor needs to use a surgical retractor to pull the surgical incision so that the surgical site can be fully exposed so that the doctor can perform the operation well. Because the size and shape of the incision is not fixed according to the patient's condition during the operation, especially for the large crescent-shaped incision, it is difficult for the retractor to effectively draw according to the wound condition. The existing solution is to use multiple sets of retractors to cooperate synchronously. , which leads to the doctor needing to fix and adjust the retractor multiple times to find a suitable traction position, which is time-consuming and laborious, which may delay the timing of the operation and reduce the success rate of the operation
