Abstract

The invention discloses an auxiliary device for hepatobiliary surgery. The device comprises a fixing frame; two ends of the inner side of the fixing frame are fixedly connected with a second connecting mechanism; a fixing mechanism is hinged to one side, away from the second connecting mechanism, of the fixing frame; a first connecting mechanism is fixed to the inner side of the fixing frame; a limiting mechanism is connected to the interior of the first connecting mechanism; a third connecting mechanism is connected to the interior of the limiting mechanism; the third connecting mechanism comprises a second connecting block, a second screw, a first gear, a third connecting cylinder, a telescopic mechanism and a third connecting block; and a second screw is fixed to one side, close to thefirst connecting frame, of the second connecting block. The device is provided with the first connecting mechanism and the third connecting mechanism, so that the device is firmly fixed. In addition,the whole device is easy to operate and is suitable for various surgical wound shapes, so that the application range of the device is widened, operation time is shortened, and the device is also suitable for flat wounds.

Description

technical field [0001] The invention relates to the technical field of surgical tools, in particular to an auxiliary device for hepatobiliary surgery. Background technique [0002] With the continuous development of society, during the recovery process of hepatobiliary surgery patients, in order to operate efficiently, it is necessary to use a device to open the abdominal cavity for easy operation. [0003] Existing but the existing abdominal cavity requires multiple medical staff to pull and stretch the tissue to facilitate the later operation. Most of the operations take a long time, and manual manual expansion increases the operating intensity of the medical staff. If a spreader is used in surgery, it is necessary to manually fix multiple spreaders to the edge of the chest cavity in sequence, but the operation of the spreader is cumbersome and takes a long time. In the case of a large spreader, only the retractors on both sides can be adjusted at the same time, so that t...
