Problems solved by technology

[0004] However, the above-mentioned device requires the doctor to manually fix the retractor for a long time during use, which consumes a lot of manpower and time, and the surgical retractor is pulled by manpower, and the wound is easily torn due to uneven manpower. The part pulled by the retractor will have blood seeping continuously, thus blocking the surgeon's sight, increasing the time and difficulty of the operation, and reducing the efficiency of the operation. Therefore, a surgical retractor for hepatobiliary surgery is needed

Abstract

The invention discloses a retractor for hepatobiliary surgery, which comprises a fixed box, a threaded rod is rotatably connected to the inner side wall of the fixed box, the end of the threaded rod runs through the outer side wall of the fixed box, and the outer side wall of the threaded rod A gear is fixedly connected to the top, a connection groove is opened on the outer side wall of the fixed box, and a locking mechanism is rotatably connected to the inner side wall of the fixed box, and the locking mechanism can abut against the outer side wall of the gear, and the threaded rod The outer wall of the fixed box is symmetrically rotated and connected with a positioning block, and a positioning groove is opened on the outer wall of the fixed box. The positioning block runs through the positioning groove, and the blood leaking from the opening during the operation can be absorbed by the blood-sucking sponge, without Repeated cleaning is required manually, thereby saving a lot of operation time. After the operation is over, the blood on the blood-sucking sponge is initially cleaned under the upward tension of the second spring, saving a lot of time for subsequent device cleaning.

Description

technical field [0001] The invention relates to the technical field of hepatobiliary surgery, in particular to a surgical retractor for hepatobiliary surgery. 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. A relatively complete theoretical and technical system has been formed in the surgical treatment of hepatocellular carcinoma, hepatolithiasis, and damaged bile duct strictures. The surgical wound is pulled to fully expose the field of vision suitable for surgery, which is convenient for doctors to perform surgery. [0003] After searching, the invention patent with the Chinese patent number CN105919635A discloses a surgical hook device for hepatobiliary surgery, including a connecting device, an elastic connecting belt, a telescopic bracket and a hook body. ...
