Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a simple external fixation device for fractures in orthopedic surgery. Background Technology
[0002] A simple external fixation device for fractures in orthopedic surgery is a medical device used to assist in the treatment of fractures. It is typically used after fracture reduction to fix the fracture site externally, maintaining the position of the fracture ends, creating a stable biomechanical environment for fracture healing, promoting healing, and preventing adverse conditions such as fracture end displacement and angulation. At the same time, the external fixation device can also reduce pain to some extent, facilitate early functional exercises for patients, and reduce the occurrence of complications.
[0003] However, existing simplified external fixation devices for orthopedic surgery consist of components such as steel pins, connecting rods, and fixation clips. By inserting steel pins through the skin into the bones at both ends of the fracture, and then connecting rods and fixation clips to connect and fix the pins, an external fixation system is formed. While convenient, existing external fixation devices are expensive and not always readily available. Therefore, we propose a simplified external fixation device for orthopedic surgery.

[0016] 1. In this utility model, during use, medical personnel select the appropriate Kirschner wires according to the fracture condition. Then, on the same plane, the drill bits at one end of the first and second Kirschner wires are drilled into one side of the fracture site as needed. Next, the first and second connecting rods are roughly installed on the first and second Kirschner wires, and the first and second Kirschner wires, as well as the first and second connecting rods, are fixed together using steel wire. Then, the drill bits at one end of the third and fourth Kirschner wires are drilled into the corresponding positions on the other side of the fracture site as needed. At this time, the medical personnel manually control the first and second connecting rods. After adjusting the angle, the first and second connecting rods are fixed to the third and fourth Kirschner wires using steel wire. Then, based on the principle of triangle stability, the first and second adjusting rods are used on another plane to reinforce the fracture in the first reinforcement method or the first and second reinforcing rods are used to reinforce the fracture in the second reinforcement method by attaching them to the corresponding positions with steel wire. After installation, the excess Kirschner wires and steel wire are trimmed off with heavy-duty shears. This simple external fixation device for fractures in orthopedic surgery is simple in structure, easy to operate, highly adaptable, and can be designed according to the needs of any fracture external fixation method. It is also economical. Attached Figure Description
