Distal radius fracture fixing device with longitudinal traction function

Abstract

The invention relates to a distal radius fracture fixing device with a longitudinal traction function. The distal radius fracture fixing device comprises a back side splint, a palmar side splint, a radial side splint and an ulnar side splint; each of the back side splint, the palmar side splint, the radial side splint and the ulnar side splint comprises a straight body plate, a buckling plate, a telescopic plate and an angle regulation and control device; the distal radius fracture fixing device further comprises a fixing device body; the fixing device body comprises fixing patches, traction belts and traction patches; the fixing patches are arranged on the straight body plate on the back side splint and the straight body plate on the radial side splint, and the back side splint and the radial side splint are connected together through the fixing patches; and the traction belts and the traction patches are arranged in front of the corresponding fixing patches. The distal radius fracture fixing device has the advantages that the structural design is reasonable, operation is easy, stable fixation can be guaranteed, the angle can be adjusted, meanwhile, continuous and effective traction can be carried out when fracture reduction adjustment is carried out on a distal radius patient, and then the distal radius patient is assisted in achieving smooth recovery of the fracture position.

Description

Technical field [0001] The present invention relates to the field of medical devices, in particular, is a humerus distal fracture fixing device having longitudinal traction function. Background technique [0002] The distal fracture of the humeral is the most common fracture in the fracture of the upper limb. The flexible distal fracture usually refers to the fracture within 3 cm in the distal end of the bone. It is the common disease of the orthopedic door emergency, and has been in the elderly and the young age. The flexible distal end participates in the formation of wrist joints, in the clinical distal fracture of the distal radius, is a common orthopedic trauma disease. When an accident occurs, the person will be used to support, so that the wrist is easily injured. [0003] Traditional intermediate distal fracture treatment is often used for surgical treatment, splint or wrist gypsum to treat flexible distal fractures, and the general splint fixation is not very stable, so ...

Problems solved by technology

In the event of an accident, people will subconsciously use it for support, so the wrist is easily injured

[0003] The traditional treatment methods for distal radius fractures often use surgical treatment, splint or wrist plaster external fixation to treat distal radius fractures. The general splint fixation method is not very stable, which makes the treatment effect unsatisfactory and may lead to easy secondary fractures. Secondary injury, leading to complications such as fracture malunion and joint dysfunction. At the same time, the splint-type fixation can only temporarily relieve the distal radius. Due to the inadvertent movement of the wrist joint of the human hand, it often causes However, the effect of plaster external fixation is not accurate, and relocation of fractures often occurs, and the plaster is heavy, and it is easy to loose and fail when it is exposed to moisture. The plaster fixation also needs to fix the wrist joint and related It is adjacent to the finger, which obviously causes inconvenience in life and work; although surgical fixation is more reliable in the treatment of radial fractures, it is an invasive treatment after all, which will bring the risk of needle tract infection, and the cost is high, and the patient's compliance is also relatively low. Difference

[0004] The patent application CN205515104U submitted by the applicant in the early stage discloses a control type distal radius fixation device, the fixation device includes a dorsal splint, a palmar splint, a radial side splint, and an ulnar splint; the dorsal splint, palmar splint Side splints, radial splints, and ulnar splints all include straight body plates, flexion plates, telescopic plates, and angle control devices; the flexion plates are hinged at the end of the straight body plate, and the hinged parts are selected as hinge shafts or latches. The device can realize adjustable angle, variable telescopic length splint shape, good shaping ability, how much degree the patient needs to control when immobilizing, and how much degree of dorsal extension is required can be realized, which not only ensures the firmness of the fixed position, but also can It allows patients to recover their functions earlier, but when the device is used, it cannot provide continuous and effective traction for patients with distal radius fractures, and cannot achieve the recovery effect of patients with distal radius fractures

[0005] So to sum up, there is an urgent need for a new type of longitudinal traction function that is simple to operate, easy to use, and can achieve continuous and effective traction for patients with distal radius fractures on the basis of adjustable angles, and improve the recovery effect. However, there is no report on this kind of distal radius fracture fixation device with longitudinal traction function.
