摘要：
A bending control mechanism includes a turning power input mechanism, a turning transmission mechanism, a locking mechanism and a linear power output mechanism. The turning power input mechanism and the turning transmission mechanism which are coaxially arranged have a relative rotating angle range in the circumferential direction； the turning power input mechanism sequentially rotates in an angle I, an angle range II and an angle III while rotating relative to the turning transmission mechanism from one end angle to the other end angle of a relative rotating angle range, wherein the angle I or the angle III corresponds to turning； the angle range II corresponds to a locking state. With the adoption of the mechanism, the problem of turning and fixing of the surgical instrument in a human body during surgery is solved, and the risk of surgery is reduced.
