Three-degree-of-freedom parallel serial joint plastic operation robot

Abstract

The invention provides a three-degree-of-freedom parallel serial joint plastic operation robot. The problems of uneven operation level of doctors and low overall precision in the present prosthesis joint replacement are solved. The three-degree-of-freedom parallel serial joint plastic operation robot comprises a workbench, wherein a vertical mechanism and horizontal mechanisms are arranged on the workbench; an abrasive drilling mechanism is arranged on each of the horizontal mechanisms; the quantity of the horizontal mechanisms is two; the horizontal mechanisms are respectively arranged on the two sides of the vertical mechanism; the vertical mechanism comprises a vertical sliding table and a vertical driving component; each of the horizontal mechanisms comprises a horizontal sliding table and a horizontal driving component; connecting arms are fixedly connected with the two sides of the vertical sliding table; an outer end of each connecting arm is hinged to the horizontal sliding table on the corresponding side; a claw arm forward extends from each of the horizontal mechanisms; a sleeve ring is arranged at the front end of each claw arm; the sleeve rings forward extending from the horizontal mechanisms on the two sides are vertically overlapped and formed into a communicated sleeve hole; the abrasive drilling mechanism is penetrated through the sleeve hole; an inner wall of the sleeve hole is in sliding contact with an outer wall of the abrasive drilling mechanism. According to the invention, a triangular structure is adopted by the robot, so that the accurate route of a three-dimensional space track is realized and the face cutting precision of a bone joint is increased.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, and relates to a bone grinding operation in prosthetic joint replacement surgery, in particular to a three-degree-of-freedom series-parallel hybrid arthroplasty surgery robot. Background technique [0002] Artificial joint replacement refers to the use of metal, high molecular polyethylene, ceramics and other materials to make artificial joint prostheses according to the shape, structure and function of human joints, and implant them into the human body through surgical techniques to replace the function of diseased joints to achieve relief. Joint pain, the purpose of restoring joint function. [0003] Artificial joint replacement requires high surgical skills for doctors. First of all, in addition to the resection of joint lesions, artificial joint replacement requires a deep understanding of the kinematics of the joint. Installing the artificial joint prosthesis at an accurate pos...

AI Technical Summary

Problems solved by technology

At present, the accuracy of artificial arthroplasty mainly depends on the doctor's experience, which undoubtedly increases the uncertainty of the operation and affects the installation accuracy of the prosthesis.
