Abstract

The invention belongs to the technical field of medical equipment, and specifically relates to a puncture device for abdominal surgery in gastrointestinal surgery, which includes a support plate, a sleeve and a puncture rod; a mounting groove is opened in the middle of the support plate; There are uniformly arranged adjusting turning blocks; the same sleeve is threadedly connected between the adjusting turning blocks; a stepped installation hole is opened inside the sleeve; a rotating block is fixedly connected to the inside of the stepped installing hole; There is an adjustment hole inside the rotating block; the same puncture rod is inserted between the ladder installation hole and the adjustment hole; the invention effectively realizes the supporting abdominal puncture operation, and solves the problem of direct puncture. Doctors need to judge whether the puncture is in place through the sense of vacuum. The puncture technique is difficult and the operation risk is high. Through the progressive spiral structure, the slow puncture operation is realized. The structure is simple and the risk of puncture is greatly reduced.
