Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic medical equipment, in particular to a joint repositioner. Background Art

[0002] In orthopedic medical surgery, the reduction and fixation of clavicle fractures and acromioclavicular joint dislocations are an operation that needs to be mastered. Most clavicle fractures are caused by direct violence such as falls. Clavicle fractures often occur in the middle 1 / 3 of the clavicle, and the two ends of the clavicle fracture often have varying degrees of upward, forward or backward displacement. The clavicle plays an important role in the movement of the acromioclavicular joint. Clinical acromioclavicular joint dislocations are usually caused by direct force on the acromion, and can also be caused by indirect injuries, such as when the hand or elbow supports the ground during a fall, and the external force is transmitted upward along the humerus to damage the acromioclavicular joint. The clavicle often has varying degrees of upward or forward displacement relative to the acromion, which can cause varying degrees of damage to the nearby ligaments, resulting in shoulder joint dysfunction.

[0003] Internal fixation methods for treating clavicle fractures include Steinmann wire fixation, bone plate fixation, and memory alloy clavicle embracing device fixation. There are many surgical methods for acromioclavicular joint dislocation, such as Steinmann wire tension band fixation, hook plate fixation, wire fixation, etc. Regardless of the internal fixation device used, the important prerequisite for the fixation of clavicle fractures or acromioclavicular joint dislocations is good intraoperative reduction and effective maintenance until fixation. After a clavicle fracture, an interdigitation is formed and the chest collapses. The traditional reduction method is to support the back with the knees, hold the shoulders with both hands, move the shoulders backwards with force, pull the interdigitation apart, and then align the fracture site. This method is time-consuming and labor-intensive, the fracture site is difficult to accurately reduce, and one person cannot complete the entire operation.

[0004] Chinese Patent No. 201210005268.5 discloses a clavicle fracture and acromioclavicular joint dislocation reduction and stabilization device, which uses a jacked-up bed board to prop up the patient's back and fix the two sides with fastening belts, effectively solving the reduction problem of clavicle and shoulder joint injuries. However, the structure of the jacking device and the fastening belt of this device is relatively simple, the adjustment is not convenient enough, the reduction effect is not satisfactory, and there is room for improvement.
