Extending fixing support frame for closed reduction surgery of supracondylar fracture of humerus in children

Abstract

The invention discloses an abduction fixing support frame for child humerus supracondylar fracture closed reduction surgery, which comprises an adjustable support leg mechanism, an adjustable support mechanism, a forearm sheath assembly and an upper arm sheath assembly, and is characterized in that the adjustable support mechanism is arranged between the forearm sheath assembly and the upper arm sheath assembly; the forearm sheath assembly comprises a forearm protection shell and a forearm lining, the forearm lining is arranged on the inner side face of the forearm protection shell, the upper arm sheath assembly comprises an upper arm protection shell and an upper arm lining, the upper arm lining is arranged on the inner side of the upper arm protection shell, the adjustable supporting mechanism comprises a supporting rod, and a threaded connection hole II is formed in the supporting rod; the threaded connection hole II penetrates through the supporting rod, and the upper end of the supporting rod is connected with an upper adjusting rod II through the threaded connection hole II. The device is novel in structural design, easy to operate, firm in fixation and convenient to adjust, can prevent an operator and an assistant from hurting the body due to radiation, and can firmly fix fracture reduction.

Description

technical field [0001] The invention relates to the technical field of surgical auxiliary equipment for supracondylar humerus fracture in children, in particular to an abduction fixation support frame for closed reduction operation of supracondylar humerus fracture in children. Background technique [0002] The joint between the medial and medial condyles of the humerus and the humeral shaft is weak and prone to fractures, which can be called supracondylar fractures of the humerus. It is more common in preschool children and is a common extra-articular fracture of the elbow. After treatment, it can usually recover smoothly, but in some cases, elbow varus malunion can occur. When the fracture displacement in adults is obvious, open reduction surgery is usually used for treatment. Clinically, supracondylar fractures of the humerus are divided into two types: extension supracondylar fractures and flexion supracondylar fractures.

AI Technical Summary

Problems solved by technology

After the fracture is flexed and reset, it is necessary to perform fluoroscopy under the C-arm, which requires the operator to hold the fluoroscopy, which increases the physical damage caused by the radiation. In the past, bandages and bottles were used to block it, but they were not fixed firmly. It is easy to cause fracture dislocation, and it is inconvenient to perform surgery. In the supracondylar humeral fracture surgery, there is a lack of fixation and support devices, and the method of blocking with bandages and bottles cannot meet the needs of actual use. Therefore, there is an urgent need for improved technology on the market. solve the above problems
