Abstract

The present invention discloses a hepatobiliary surgical tractive device for conveniently adjusting opening sizes and aims at problems that traditional surgical tractive device is single in structureand poor adjustability, and cannot meet more use requirements. A current provided scheme is as follows: the hepatobiliary surgical tractive device comprises two placing seats in a left and right arrangement, the two placing seats are fixedly provided with a L-shaped right connection block and a L-shaped left connection block in a corresponding manner, transverse thread holes are arranged in both rear ends of the L-shaped right connection block and L-shaped left connection block, rotation directions of threads of the two thread holes are opposite, front ends of the L-shaped right connection block and L-shaped left connection block respectively pass through a vertical right limiting rod and a left limiting rod, and deviation sides of the left limiting rod and right limiting rod are both fixedly provided with vertical fixing plates. By arranging support plates, the placing seats, a rotary knob ring, a threaded rod, the L-shaped right connection block and the L-shaped left connection block, the hepatobiliary surgical tractive device facilitates opening of an opening and also keeps the opening state for long time, is convenient for surgeries, and can adjust the opening sizes by rotatingthe rotary knob ring.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a traction device for hepatobiliary surgery that facilitates the adjustment of the size of the opening. Background technique [0002] Hepatobiliary surgery mainly treats diseases such as hepatobiliary and pancreatic tumors, cholelithiasis, and portal hypertension. In current clinical treatment, when liver tumors, liver cysts, gallbladder stones, and tumors are resected under laparoscopy, it is often necessary to use surgical instruments to lift the liver tissue, or to separate and pull the lesion and surrounding tissues. For the smooth operation, the wound can be opened through the hand pulling device to fully expose the surgical area. The traditional pulling device has a simple structure and poor adjustability, and cannot meet more usage needs. Contents of the invention [0003] A traction device for hepatobiliary surgery that is convenient to adjust the size of the opening pro...
