technical field

The invention belongs to the technical field of medical devices, and in particular relates to an orthopedic auxiliary traction device.

Background technique

Traction is a commonly used technique in orthopedic adjuvant therapy. It is not only a means of fracture reduction, but also a measure to maintain reduction. The principle of traction is to use traction force and anti-traction force to act on the fracture site to achieve the purpose of reduction and maintenance of reduction. Its main functions are: (1) slow traction to achieve fracture reduction and maintain reduction, correct shortening and angular displacement, prevent malunion, and bring convenience to surgery. For some fractures, it can also be used as an ultimate treatment method; (2) prevent Excessive displacement of the broken end stimulates the soft tissue, reduces secondary soft tissue damage and bleeding, and relieves the pain of the patient; (3) While waiting for the operation, relax the muscles around the broken end of the fracture, reduce the soft tissue adhesion of the broken end, reduce the difficulty of reduction, and reduce the pain during the operation. Soft tissue stripping and bleeding, shortening operation time;

At present, during the treatment of diseases in the orthopedics department of the hospital, traction is usually required. When the medical personnel perform traction on orthopedic patients, they need to use a traction bed. The traditional traction bed has a relatively simple structure and a relatively single function.
