Precise positioning device for fracture surgery

Abstract

The invention discloses a precise positioning device for fracture surgery, which belongs to the field of medical surgery and comprises a handle, a telescopic pressing head fixed at the front end of the handle and internally provided with a guide through hole, and a positioning hook wrapping a fracture position. One end of the positioning hook is fixed at the front end of the handle, and the other end of the positioning hook is matched with the telescopic pressing head to clamp and fix a fracture part and position a kirschner wire; the positioning hook is an adjustable positioning hook of which the size is adjustable; the kirschner wire can be rapidly and accurately drilled into the fracture position, unnecessary repeated puncture of the kirschner wire is avoided, later hollow screw placement is facilitated, the operation time is shortened, the operation difficulty is reduced, and postoperative rehabilitation is accelerated.

Description

technical field [0001] The invention relates to the field of medical operations, in particular to a precise positioning device for fracture operations. Background technique [0002] A fracture is a medical condition in which the continuity of the bone is partially or completely broken. In severe cases, the bone may be broken into several pieces; the fracture can be caused by a strong impact or pressure; Internal fixation (steel plate screws or simple hollow nails), until the scab heals, in fracture surgery, such as femoral condyle or humeral condyle fracture surgery, the doctor usually clamps and fixes the separated part of the fracture with a clamping device, and then drives it into the gram The wire is used to position and guide the hollow screw to be drilled, and it is generally difficult to accurately judge the position of the inserted Kirschner wire. If the position of the Kirschner wire is not good, the doctor often needs to repeat the Kirschner wire trial and error fo...

[0002] A fracture is a medical condition in which the continuity of the bone is partially or completely broken. In severe cases, the bone may be broken into several pieces; the fracture can be caused by a strong impact or pressure; Internal fixation (steel plate screws or simple hollow nails), until the scab heals, in fracture surgery, such as femoral condyle or humeral condyle fracture surgery, the doctor usually clamps and fixes the separated part of the fracture with a clamping device, and then drives it into the gram The wire is used to position and guide the hollow screw to be drilled, and it is generally difficult to accurately judge the position of the inserted Kirschner wire. If the position of the Kirschner wire is not good, the doctor often needs to repeat the Kirschner wire trial and error for many times. Only in this way can it be convenient to accurately drill into the hollow screw to fix the fracture in the later stage. This multiple puncture operation is likely to cause bone tissue damage or rupture), which increases the difficulty of the operation, reduces the efficiency of the operation, and is not conducive to shortening the recovery time
