Device for additional bone osteotomy in knee arthroplasty

摘要

The utility model relates to surgical instruments and relates to the field of medicine, in particular to orthopedics, and can be used during knee arthroplasty. The technical result of the proposed device for additional osteotomy of the bone is to simplify the repeated resection of the bone, reduce the duration of the surgical intervention, perform sawdust parallel to the primary plane, and reduce the trauma of the surgical intervention. The device consists of a guide plate, fixedly connected to the body of the block for osteotomy, the plate is installed on the surface of the primary osteotomy and orients the plane of the repeated osteotomy parallel to the original sawdust. Through holes are made in the body of the block for osteotomy, intended for fixation to the bone by means of pins. Also, through grooves are made in the block body, through which an additional osteotomy is performed using an oscillator saw blade.
