Description

A calcaneal distraction device with hemostatic structure

technical field

The utility model belongs to the technical field of medical devices, in particular to a calcaneus traction device with a hemostatic structure.

Background technique

Traction technology is a commonly used treatment method in orthopaedics. Through the traction device, the weight of the suspension is used as the traction force, and the body weight is used as the anti-traction force to relieve muscle tension and strong contraction, restore fractures and dislocations, prevent and correct soft tissue contractures, and treat certain diseases. It is a treatment method of preoperative tissue release and postoperative immobilization for some diseases, mostly used in the extremities and spine. Traction therapy includes bone traction, skin traction, and Bhutto traction.

The calf is mostly a "skin and bone" structure. When the tibia is fractured, the calf is often swollen due to the insertion and bleeding of the fractured end. In clinical practice, Klinefelter is usually used to fix and distract the calcaneus to reduce the fracture. When the Kirschner wire is inserted into the patient's calcaneus, it will bleed from the damaged skin, and due to the existence of the traction device, it is very inconvenient to bandage the wound for hemostasis.
