Problems solved by technology

[0002] At present, in orthopedic surgery, such as comminuted long bone fractures, large fragments need to be surrounded, bound, and fixed with steel wires. Piercing is quite inconvenient. Even experienced operators still need multiple piercings to succeed, and the muscles may be damaged during the process. In some cases, the operation cannot be completed, which brings serious troubles to the operation and prolongs the operation. time increases bleeding

Abstract

The invention discloses a wire threading device, which comprises a first duct and a second duct, wherein the first duct is provided with a first cured embracing arm, a first wire threading path is assigned in the first cured embracing arm, and at least one wire threading mouth connecting with the first threading path is assigned on the exterior of the cured embracing arm. The second duct is provided with a second cured embracing arm, the second cured embracing arm is docked with the first cured embracing arm, and then form a embracing hole which is close to the surface of bones and embraces the fracture site. A second wire threading path is assigned in the second embracing arm, the second wire threading path is docked with the first wire threading path, and at least one wire threading mouth connecting with the second wire threading path is assigned on the exterior of the second embracing arm. In the orthopedic surgery, the wire thread device can thread wires with a high speed, thereby the phenomenon that wires prick the vascular nerve and the soft tissues around the fracture site can be avoided, and the bone healing speed can be improved.

Description

technical field [0001] The invention relates to a steel wire threader, which belongs to the technical field of medical instruments. Background technique [0002] At present, in orthopedic surgery, such as comminuted long bone fractures, large fragments need to be surrounded, bound, and fixed with steel wires. Piercing is quite inconvenient. Even experienced operators still need multiple piercings to succeed, and the muscles may be damaged during the process. In some cases, the operation cannot be completed, which brings serious troubles to the operation and prolongs the operation. Time increases the amount of bleeding. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a steel wire threader, which can quickly realize the threading of the steel wire in orthopedic surgery, and avoid the damage of the steel wire to the blood vessels, nerves and soft tissues around the fractur...
