Fixing device for traumatic orthopedics department

Abstract

The invention discloses a fixing device for the traumatic orthopedics, and relates to the technical field of orthopedic rehabilitation instruments. The fixing device comprises a big arm fixing mechanism, a forearm fixing mechanism and a locking mechanism, wherein the big arm fixing mechanism is in fixedly sleeving to the big arm; the forearm fixing mechanism is abutted against a gypsum cylinder on the forearm; one end of the forearm fixing mechanism is connected to the big arm fixing mechanism through a hinge shaft; the hinge shaft is configured to enable the forearm fixing mechanism to only swing up and down relative to the big arm fixing mechanism; and the locking mechanism is assembled to be capable of locking the rotational degree of freedom of the hinge shaft and capable of unlocking. According to the fixing device for the traumatic orthopedics department, the forearm of a patient only can swing to be bent or straightened, and the forearm is prevented from rotating relative to the big arm so as to be favorable for protecting the fracture part of the forearm. The locking mechanism is arranged, when the fracture of the forearm is serious or th fracture position of the forearm is close to the elbow, the forearm can be prevented from swinging relative to the big arm, and therefore, the forearm is prevented from moving relative to the big arm so as to be favorable for healing of the fracture part.

Description

technical field [0001] The invention relates to the technical field of orthopaedic rehabilitation equipment, in particular to a fixation device for trauma orthopedics. Background technique [0002] Fracture is one of the most common diseases in trauma orthopaedics, which is characterized by complete or partial rupture of the continuity of bone structure. In the treatment of fractures, it is first necessary to restore the displaced fracture ends to normal or close to the original anatomical relationship, so as to restore the scaffolding function of the bones; The method of fixing it in a satisfactory position to make it heal gradually. Commonly used fixation methods include splint, plaster bandage, external fixation bracket, etc. These fixation methods are called external fixation. Fixation with internal needles, screws, etc. is called internal fixation; finally, it is necessary to actively or passively move the unfixed joints to increase the blood circulation of the tissues...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, patients with forearm fractures are relatively common. For such patients, the forearm fracture site after reduction is fixed no matter through plaster bandages, splints, or brackets. The forearm can swing relative to the big arm to bend Or straighten, but there are also the following defects. One is that the overall rotation (twisting) of the forearm cannot be prevented. The rotation of the forearm will cause a load on the fracture site. The second is that when the fracture site of the forearm is close to the elbow, The movement of the forearm relative to the upper arm should be avoided as much as possible. The above methods cannot prevent the swing of the forearm relative to the upper arm, which will affect the patient's recovery progress
