Orthopedic joint replacement operation positioning platform

Abstract

The invention discloses an orthopedic joint replacement operation positioning platform, which is characterized by comprising a bed board and a supporting and positioning part, a left groove body and a right groove body are formed in the lower side of the bed board, and the supporting and positioning part is arranged on the left groove body or the right groove body in a matched mode. The supporting part comprises a seat body, a first supporting plate, a second supporting plate and an osteotomy part, the first supporting plate is used for supporting a thigh part, the second supporting plate is used for supporting a shank part, and one end of the first supporting plate is longitudinally hinged to one end of the second supporting plate through a hinge part; the upper limbs and the lower limbs of a surgical patient are supported through the first supporting plate and the second supporting plate, the legs can be well supported in osteotomy and prosthetic replacement, the knee bending angle can be changed according to actual needs through relative longitudinal hinge of the first supporting plate and the second supporting plate, and various lower limb orthopedic surgery requirements are met.

Description

technical field [0001] The invention relates to medical equipment, in particular to a positioning platform for orthopedic joint replacement surgery. Background technique [0002] Knee replacement is a joint replacement operation. This operation is very common in orthopedic surgery. Simply put, it is to replace the damaged cartilage in the knee joint that affects the normal movement of the joint, and the drumhead below it. The artificially designed prosthetic components for adults need to be replaced by surgery, osteotomy, implantation of the prosthesis, and cleaning of the articular surface. Each of these steps must consider whether the relevant functions will be affected, whether the prosthesis is suitable, and whether it is firm 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 surgery, the knee cannot wait for better support during the operation o...

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
