The invention discloses a surgical instrument with multi-degree-of-freedom steering control, the surgical instrument comprises an operating forceps assembly, a steering section, a guide rod and a handle which are sequentially connected in series from front to back, the steering section comprises a plurality of steering knuckles which are connected in series in a hinged mode, the front hinge direction and the rear hinge direction of the steering knuckles are perpendicular to each other, the steering knuckles are provided with four through holes which are in groups perpendicular to each other, four pull ropes penetrating through the corresponding through holes respectively are arranged in the guide rod, two winding wheels which are spaced by 90 degrees around the guide rod are rotatably arranged on the rear portion of the guide rod, the front ends of the pull ropes are connected to the rear portion of the operation forceps assembly, the rear ends of the pull ropes are wound on the winding wheels, the two pull ropes corresponding to the same group of through holes are wound on the same winding wheel in the opposite directions, the handle is connected with the two winding wheels through two chain belts in the direction of the guide rod, each chain belt comprises a plurality of chain links which are hinged and connected in series, and the front hinge direction and the rear hinge direction of the chain links are the same. The operation forceps assembly can synchronously swing along with the up-down and left-right directions of the handle only by operating the handle, so that the risk is reduced.
Description
technical field [0001] The invention belongs to the field of surgical instruments, in particular to a surgical instrument with multi-degree-of-freedom steering control. Background technique [0002] When the current surgical manipulator needs to swing the front joint, it needs to apply a reverse force to the rear guide rod, so the guide rod will vibrate under the force, affecting the operation of the front end, which has certain risks. Contents of the invention [0003] The purpose of the present invention is to provide a surgical instrument with multi-degree-of-freedom steering control, which can swing synchronously with the handle up, down, left, and right only by operating the handle operating forceps assembly, which reduces risks, is simple to operate, and occupies less space as a whole. [0004] The technical scheme adopted in the present invention is: [0005] A surgical instrument with multi-degree-of-freedom steering control, including an operating forceps assembl...
