Abstract

The invention discloses a sliding located draw hook for surgical operations of livers and gallbladders. The sliding located draw hook comprises a supporting frame, wherein a fixing base which is usedfor being fixed onto an operation table is fixedly arranged at the bottom of the supporting frame, a rectangular frame is fixedly connected to the top of the right side of the supporting frame, a rectangular sliding sleeve sleeves the rectangular frame in a sliding manner, and a first locating locking bolt which is used for carrying out locking locating on the rectangular sliding sleeve is arranged at the upper part of the rectangular sliding sleeve. According to the sliding located draw hook, the trouble that a doctor needs to manually draw draw hooks is avoided, time and labor are saved, theinvestment of personnel is reduced, and the pressure of working personnel is also alleviated; positions and angles of two draw hooks and width of draw-apart of a wound can be conveniently adjusted, and the doctor can conveniently operate and use the draw hooks; and meanwhile, movable rods and the draw hooks can be more stable during wound stretching, the condition of getting loose difficultly occur, and the successful proceeding of the operations is guaranteed.
