Bone holder for femoral subtrochanteric osteotomy

Abstract

The invention discloses a bone holder for femoral subtrochanteric osteotomy, which comprises a bone holding plate and a plurality of bone holding clamps, one ends of the bone holding clamps are provided with fixing parts fixed with the bone holding plate, when the fixing parts are loosened, the bone holding clamps slide relative to the bone holding plate, and after bone blocks are cut off, two flat anastomotic surfaces can be provided, so that the bone blocks can be cut off. The device is used for clamping the wounded femur, and rotation of the broken ends of the femur during splicing is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a bone holder for subtrochanteric osteotomy. Background technique [0002] Subtrochanteric osteotomy has a wide range of indications. In this study, the osteotomy was applied to IV degree DDH for total hip arthroplasty to avoid excessive lengthening of the lower limbs, resulting in sciatic nerve, blood vessel injury and difficulty in reduction; Subtrochanteric osteotomy methods include horizontal osteotomy, oblique osteotomy, wedge-shaped osteotomy, Z-shaped osteotomy, etc. At present, horizontal osteotomy is the most commonly used clinically, and two ordinary bone-holding forceps are used by assistants during osteotomy The surgeon cuts the femur. During the osteotomy, due to the swing of the saw blade, it is difficult for the assistant to keep the pliers and the clamped femur in a fixed position, so the cut surface is often uneven, and the bone fragment is broken in two The ends ...

During the osteotomy, due to the swing of the saw blade, it is difficult for the assistant to keep the pliers and the clamped femur in a fixed position, so the cut surface is often uneven, and the bone fragment is broken in two The splicing of the ends is very inconsistent, which is not conducive to the healing of the fracture, thus affecting the effect of the operation. Therefore, a tool is needed to assist the cutting
