Adjustable fixing device used for fracture of wrist joint

Abstract

The invention discloses an adjustable fixing device used for fracture of a wrist joint. The fixing device comprises a fixing device main body, an adjusting device and a magnetic therapy belt. The fixing device main body comprises an arm fixer and a palm fixer. The palm fixer is of a hollow semi-circular structure. Elongated sliding grooves are arranged in horizontal positions of front and back sides of the palm fixer. Moving sliding blocks are arranged in the elongated sliding grooves. One end of the adjusting device is connected with the moving sliding blocks and the other end of the adjusting device is connected with front and back sides of the palm fixer. The upper end of the adjusting device is a telescopic rod and the lower end of the adjusting device is a fixed rod. The lower part ofthe palm fixer is connected with a palm constraint belt. In this way, the fixing device is simple in structure and proper in design; through the palm fixer, the hand part is allowed to move in a proper range; comfort level and stability during fixing of the wrist joint are ensured; the intensity during the movement is controlled; secondary hurt is avoided.

Description

technical field [0001] The invention belongs to the technical field of orthopedic medical devices, and in particular relates to an adjustable fixation device for wrist joint fractures. Background technique [0002] When fractures occur around the wrist joint, the existing main treatment methods are internal fixation or external fixation. Internal fixation treatment has large wounds, heavy bleeding, long operation time and complicated operation. It is not suitable for the treatment of open fractures and requires a second operation to remove the implants. Although external fixation treatment has the advantages of small wound, less bleeding, short operation time, can meet the treatment of open fractures, and does not require secondary surgery, etc. When a fracture occurs around the wrist joint, the fixation of the wrist joint can cause blood supply disorders in the tissues around the wrist joint, causing tissue ischemia and hypoxia, resulting in disuse changes in the joint cap...

AI Technical Summary

Problems solved by technology

When a fracture occurs around the wrist joint, the fixation of the wrist joint can cause blood supply disorders in the tissues around the wrist joint, causing tissue ischemia and hypoxia, resulting in disuse changes in the joint capsule, ligaments, surrounding tissues and bones, and eventually causing joint damage. Fibrous ankylosis and functional impairment, although the blood supply of the tissues around the joints is restored after the limb joints are removed from the brake, and the slight movement of the joints improves the nutrition of the tissues and gradually restores the degeneration of the joint tissues. extremely slow

[0003] When external fixation is used to treat wounds around the wrist joint, it is usually necessary to fix the wrist joint, which restricts the movement of the wrist joint and prevents early exercise of the wrist joint. Due to the long fixation time (usually 4-6 months or even longer), After the wrist fracture is cured until it heals, stiffness will also occur around the wrist joint, which will damage the joint function. The dysfunction of the wrist joint will also seriously affect the flexibility of the hand. After the palm deviates from the best fixed position, it can be treated in time Reaction force, so that the palm can move within a certain range, which can not only prevent the wrist joint from being stiff and damaged, but also prevent the wrist joint from being injured during activities.
