Description

Encircling bone separating forceps for fracture of ulna and radius shaft

Technical Field

The utility model relates to the technical field of medical appliances, in particular to encircling bone separating forceps for fracture of ulna and radius.

Background

Bone-setting subjects are mainly injuries of bones, joints and soft tissues caused by external forces, but also include internal organ injuries caused by similar reasons. Bone setting is mainly divided into fracture and dislocation, and fracture refers to a disease in which bone is partially or completely broken due to trauma or pathology. The direct violence or the indirect violence acts on limbs or trunk to cause local bone fracture or dislocation; in addition, due to the local stress, the different body positions and the contraction of muscles, etc., various types of fracture can be caused, and the reduction method is different due to the different types of fracture. In traditional Chinese medicine, the main eight techniques of pulling, stretching, rotating, top folding, rotating, end lifting, right pressing, bone separation and bending are utilized to treat fracture, dislocation and other diseases.

The forearm of a human body is an important joint part which is more used and has wider effect, and is also a multiple part of fracture, and most of radius fractures do not need surgical treatment, because most of radius fractures are stable fractures or fractures which do not involve joints. The displacement is obvious, if the reduction effect can be good after reduction, or the stability of fracture can be better maintained through the splint or the gypsum, the conservation treatment can be completely realized.

In the bone setting technique, the diaphysis shift reposition is usually carried out by adopting the principle of separation and combination, generally, a bone setting doctor usually has a vice shape with two hands, thumbs and other four fingers of the two hands respectively buckle the gap between the ulna and the radius diaphysis, the two thumbs are mutually propped against each other to overturn, and the ulna and the radius are outwards broken, thereby achieving the purpose of separating and separating bones and facilitating diaphysis reposition. However, in the actual bone setting process, when the bone is divided, the force of some bone setting doctors cannot be reached, the dislocation and displacement of the ulna and the radius shaft are difficult to divide the bone and reset, and when the bone is divided, the bone setting doctors are particularly hard, the pressure is high, the bone is divided once, and the pain of patients is aggravated; meanwhile, after bone separation and reduction, a special assistant is required to hold the reduced forearm so as to facilitate the bone setting doctor to fix the splint and the plaster, thereby wasting human resources.
