Surgical instrument with universal locking structure

Abstract

The utility model discloses a surgical operation instrument with universal locking structure is constituted by the distal tool, control handle, shaft pipe and cable actuating device. The proximal end flexible member periphery sets up ball -locking ring device, include: hollow ball member, with the annular groove spherical surface sliding fit of fixed in control handle distal end, the annular groove both sides web is cut into open hole. Left and right belt with opposite clockwise direction cross winding annular groove, and the first end is fixed in lower web, and the second end is connected in control handle distal end the connecting block that can slide up and down jointly, and the inboard alignment open hole place of belt is bonded locking piece rubber sheet. Locking actuating subassembly is composed of trigger, rotating member and connecting block, and the trigger drives rotating member rotation when sliding along handle distal end downside, and then drives the connecting block up and down movement, makes the belt tighten or loosen, to lock or release hollow ball member, realizes the quick locking and unlocking of distal tool posture. The structure can improve the operation efficiency and safety significantly.
