Description

Technical Field

[0001] The present invention relates to the field of fracture traction instruments, and particularly to a new type of fracture traction power machine. Background Art

[0002] Fracture is a common orthopedic disease. Almost all bones are likely to fracture. For some fractures, due to the relatively stable structure of the bone itself, only simple bandaging and fixation are required for conservative treatment (such as rib fractures). However, taking long bones of the extremities as an example, after fracture, traction is usually required to solve problems such as fracture shortening, deformity, and poor alignment, so as to create conditions for subsequent surgical treatment.

[0003] The existing treatment plan is as follows: After using a skin traction belt or a drill to insert a bone traction needle, connect a traction rope, a pulley, a traction bracket, etc., and then use a weight or the like at the end to provide continuous pulling force. Although it is simple, there are many problems: ① There are many components, which is difficult to prepare completely on-site except in hospital scenarios, and it occupies a large amount of space in the hospital. ② It is not convenient for the transfer of patients and other work, and it is easy for components to fall off and even cause secondary injuries. ③ In special scenarios (such as war and disaster relief), in the case of a large number of wounded, even with support from the rear, it is relatively complicated and delays a lot.
