An orthopedic joint replacement surgery positioning platform

Abstract

The invention discloses a positioning platform for orthopedic joint replacement surgery, which is characterized in that it comprises a bed board and a supporting positioning part, the lower side of the bed board is provided with a left groove body and a right groove body, and the supporting positioning part is adapted to be arranged On the left tank body or the right tank body, the support positioning part includes a base body, a first support board, a second support board and an osteotomy part, the first support board is used to support the thigh, and the second support board is used to To support the lower leg, one end of the first support plate and one end of the second support plate are vertically hinged through a hinge component. The present invention supports the upper limbs and lower limbs of the surgical patient through the first support plate and the second support plate, which is convenient In osteotomy and prosthesis replacement, the leg is well supported, and the relative longitudinal hinge of the first support plate and the second support plate makes it possible to change the knee flexion angle according to actual needs and adapt to various lower limb orthopedic surgery needs.

Description

technical field [0001] The invention relates to medical instruments, in particular to a positioning platform for orthopaedic joint replacement surgery. Background technique [0002] Knee replacement is a joint replacement surgery. This surgery is very common in orthopaedic surgery. Simply speaking, it is to replace the damaged cartilage in the knee joint that affects the normal activities of the joint, and the drum surface below it. The artificially designed prosthesis component, the replacement is to perform an osteotomy, implant the prosthesis, and clean the articular surface through surgery. Each of these steps must take into account whether the relevant function will be affected, whether the prosthesis is suitable, and whether it is strong enough after fixation, etc. [0003] At present, knee replacement surgery is generally performed on a conventional operating bed, which has many problems. For example, in knee joint surgery, during the knee flexion operation, the knee...

AI Technical Summary

Problems solved by technology

[0003] At present, knee replacement surgery is generally performed on a conventional operating bed, which has many problems. For example, in knee surgery, the knee cannot wait for better support during the operation of knee flexion, which is not conducive to maintaining the position of the bone. Cutting of tissues and placement of prostheses; osteotomes generally need to be positioned by inserting nails, so during the operation, bone tissue defects in non-treatment positions are caused, especially after misoperation of positioning, re-insertion, After implanting at a position close to the original round hole, the osteotomy device will easily be displaced during the operation, resulting in inaccurate positioning and osteotomy volume, resulting in errors in the fit of the prosthesis, affecting postoperative healing and secondary surgery. risks of surgery
