The rotation control mechanism comprises a joint part and a control part, the joint part comprises a plurality of joint parts and at least one flexible rotating part, the plurality of joint parts are sequentially arranged in the length direction of the joint part, at least one flexible rotating part is arranged between at least part of adjacent joint parts, and the flexible rotating part is connected with the joint part. The flexible rotating piece is provided with a cavity, the cavity is filled with filling materials, the control part comprises a steering control wire, and the steering control wire is sequentially and movably connected with the multiple joint pieces in the length direction and used for controlling the steering action of the joint parts. According to the rotation control mechanism and the surgical instrument, when the joint part conducts pitching motion and deflection motion, each flexible rotating piece can conduct pitching motion and deflection motion, and the pitching freedom degree and the deflection freedom degree can be kept in the same plane; the structure can meet the requirement that the joint part does not bounce in the subsequent rolling movement process.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a rotation control mechanism and a surgical instrument. Background technique [0002] The joint structure used on the end of a minimally invasive surgical instrument usually has a pitch function and a yaw function. The realization of the pitch function and the yaw function usually decouples the pitch degree of freedom and the yaw degree of freedom, and the pitch degree of freedom and the yaw degree of freedom are designed separately Separate control on different planes, this control method has the advantages of simple structure and precise control when only pitching and yaw operations are required without rolling operations. [0003] However, with the development of technology, more and more minimally invasive surgical instruments need to introduce rolling operation, especially the rolling operation after the pitching operation and yaw operation. The introduction of r...
