Auxiliary instrument for gastrointestinal surgery

Abstract

The invention relates to the technical field of surgical operations, and discloses an auxiliary instrument for gastrointestinal surgery. The auxiliary instrument for gastrointestinal surgery comprises two fixing blocks; clamping grooves are adopted, the two fixing blocks are inserted into two operating table rods through the clamping grooves; first fixing bolts are inserted into screw holes and is screwed down; the operating table rods are clamped by the first fixing bolts, and completing preliminary fixation is achieved; a reinforcing plate is additionally arranged at the bottom of the fixing blocks, second fixing bolts are screwed into reinforcing holes; elastic blocks at the top of the reinforcing plate are adopted to compress the operating table rods, so that the stability of fixationis improved; a rotary adjusting knob is adopted, a connecting rod is adopted to drive a vertical gear to rotate, so that a transmission toothed chain is driven to move, two rotating cylinders can synchronously rotate in a bearing, a threaded moving rod is driven to move up and down under the thrust of threads, a fixing box can be adjusted to move up and down, lifting of the whole instrument is completed, the precision is higher, and the purposes of accurate height adjustment and good stability are achieved.

Description

technical field [0001] The invention relates to the technical field of surgery, in particular to an auxiliary instrument for gastrointestinal surgery. Background technique [0002] General surgery mostly uses surgery to treat liver, biliary tract, pancreas, gastrointestinal, anorectal, and vascular diseases. When treating gastrointestinal diseases, auxiliary devices such as spreaders are usually needed to assist doctors in performing operations. [0003] There are various surgical aids on the market. For example, Chinese patent CN 105769262B discloses a gastrointestinal surgical aid, which includes a fixed frame, a lead screw 1 and a first support rod. The frames on both sides of the table are fixedly connected, the two ends of the upper surface of the fixed frame are symmetrically welded with sleeves, the inside of the sleeve is fitted with a sliding rod, and the surface of the sleeve and the sliding rod is evenly opened with through holes, the sleeve and the sliding rod C...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an auxiliary instrument for gastrointestinal surgery, which has the advantages of precise height adjustment and good stability, and solves the problem that when the height of the device is adjusted, bolts are inserted into through holes of different heights. Adjust the height, the height adjustment method is too simple, the height adjustment is not accurate enough, it is easy to appear high or low, and when the device is fixed to the frame of the operating table, it is only fixed with fixing bolts, so that the device is not fixed enough Stable, and the opening of the device is controlled by a motor, which is prone to accidental touch or motor failure, causing the device to automatically open, causing harm to the patient, making the safety and stability of the device poor
