A kind of clubfoot osteotomy orthopedic guide

Abstract

The invention discloses an orthopedic guide for club foot osteotomy. It includes a varus foot orthotic device and a plantar detection plate position calibration and measurement device; the varus foot orthotic device includes a thimble, a connecting plate, a ruler, a connecting column, a lower feed block, an arc track, and an upper feed block, and the thimble It is connected with the scale through a connecting plate, and the scale is provided with a vernier, and the vernier is provided with a positioning rod; the position calibration measurement device for the sole detection plate includes a rear heel board, a front sole board, three height difference measuring rulers, and the calf is fixed. mechanism, the rear heel plate is fixedly connected with the lower feed block by the rear heel connection plate, and the front sole plate is connected and fixed with the upper feed block by the front sole connection plate. The present invention can realize the accurate finding of the position of the osteotomy surface and the position of screwing in, accurately select the angle of the osteotomy surface, can improve the accuracy of determining the loosening length of the soft tissue, and provide a more scientific basis for clinical practice.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a clubfoot osteotomy orthopedic guide. Background technique [0002] Talipes equinovarus is the most common foot deformity. The formation of clubfoot is mainly due to the imbalance of foot muscle strength. The imbalance of muscles will form bone and joint deformities over time, and the deformity will be more serious due to weight bearing on the basis of the deformity. Clubfoot deformity is composed of three factors: foot drop, varus, and adduction. Orthopedic surgery is an important treatment. The goal of clubfoot orthopedics is to establish a painless and weight-bearing plantar foot. The line of force between the foot and the calf is very important. The ideal line of force should be that the foot is opposite to each other after correction The calf is in the neutral position of flexion and extension, externally rotated 5°, and valgus 5°. The operation is usually wedge-shaped ost...

Problems solved by technology

At present, in clinical application, the corrective effect of the weight-bearing plane of the foot after the operation can only be estimated based on the surgeon’s visual inspection and hand feeling, which results in poor surgical treatment effect, and the patient’s foot has a large local stress when walking after the operation, resulting in abnormal gait and poor Local soft tissue wear, etc., will ultimately affect the patient's recovery
