Unicompartmental kenn arthroplasty (UKA) lower limb floating position holder

Abstract

The invention discloses a lower limb floating position frame for unicondylar replacement, which includes a support rod, an air cushion and a footrest. The top end of the support rod is a horizontal bar; Installed vertical rod: the slider lock is inserted into the cross bar; the top of the slider lock is inserted into the support rod of the air cushion; and the slider lock can move left and right and be fastened by the fastening bolt installed at the bottom One side of the air cushion is provided with an air outlet and an air inlet; the middle of the vertical rod is provided with a slider lock 2 that can move in four directions; the left and right directions of the slider lock 2 are inserted horizontally The connecting rod; the front end of the connecting rod is connected with a pedal. The use of the lower limb floating position frame for unicompartmental replacement can not only prevent the swing of the lower limb during tibial osteotomy, but also facilitate the operation, reduce the fatigue of the doctor, and reduce the postoperative pain and pain caused by the compression of the popliteal fossa of the patient. Paralysis, increasing patient satisfaction.

Description

technical field [0001] The invention belongs to the field of operating equipment for unicondylar replacement of knee joints, and in particular relates to a lower limb floating position frame for unicondylar replacement. Background technique [0002] Unicompartmental knee arthroplasty (UKA) is a surgical method for treating unicompartmental lesions of the medial or lateral tibiofemoral joint. In recent years, with the optimization of prosthesis design, reasonable patient selection, and mature surgical techniques, the long-term survival rate of patients after UKA has been significantly improved, and unicompartmental knee arthroplasty has been accepted by more and more patients. In the UKA operation, the traditional supine position and the single lower limb suspended position can be used for surgery. The traditional supine position is not conducive to the doctor's judgment on the placement of the prosthesis and the line of force. The supine position often cannot effectively en...

AI Technical Summary

Problems solved by technology

Since UKA puts more emphasis on precise osteotomy in order to obtain a good line of force for prosthesis installation, the traditional lower limb position frame, when performing vertical tibial osteotomy and horizontal osteotomy, is mostly artificially fixed due to the floating of the lower limbs to prevent swinging during osteotomy. The accuracy of osteotomy is greatly reduced, which is a potential threat to the accurate placement of prostheses and increases the fatigue of doctors
