An auxiliary instrument for gastrointestinal surgery

Abstract

The invention discloses an auxiliary instrument for the gastrointestinal surgical operation. The auxiliary instrument comprises fixing racks, a screw I and a first support rod, wherein the fixing racks are fixedly connected with the frames on the two sides of an operating table through tightening bolts, sleeves are symmetrically welded to the two ends of the upper surface of each fixing rack, a slide bar is mounted inside each sleeve in a matched manner, through holes are uniformly formed in the surfaces of the sleeves and the slide bars, a connecting bolt is additionally arranged into the corresponding holes of each sleeve and each corresponding slide bar, a cross bar is welded to the upper ends of the corresponding slide bars, two ends of each of the screw I and a screw II are connected with the cross bars through bearings, the right end of the screw I is connected with a servo motor I, and the servo motor I and a servo motor II are fixedly connected with the cross bars on the corresponding sides through mounting brackets, and are connected with controllers on the side surfaces of the fixing racks through leads. The auxiliary instrument has a series of advantages that the wound is expanded automatically, the applied force is accurately controlled, the use stability is high, etc.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary device for gastrointestinal surgery. Background technique [0002] In general surgery, surgery is often used to treat liver, biliary tract, pancreas, gastrointestinal, anorectal, and vascular diseases. When treating gastrointestinal diseases, a spreader is usually needed to assist the doctor's work. The common spreader is mostly composed of gears and racks. The driving mechanism is locked by the exposed ratchet mechanism, but the locking mechanism is not covered, and it is easy to touch by mistake, and the rack or ratchet is easy to fall into the abdominal cavity when the teeth collapse, causing medical accidents, and most of the existing spreaders are manual. Apply force to drive, which requires experienced old doctors to avoid wound rupture caused by excessive force. For this reason, we propose an auxiliary instrument for gastrointestinal surgery.
