Description

An orthopedic finger recovery device

Technical field

The invention relates to the technical field of medical devices, specifically an orthopedic finger recovery device.

Background technique

An orthopedic finger recovery device is a device used to aid recovery after a finger fracture, dislocation, or finger joint surgery. It is designed to maintain proper finger alignment, provide stable support and protection, and promote fracture healing and restoration of finger function.

Common orthopedic finger restoration devices include: 1. Finger correction brace: This device is usually made of metal or plastic materials and is used to fix and stabilize finger fractures. It helps maintain proper alignment of the fracture site and reduces the impact of movement and external forces on the fracture point. 2. Finger external fixator: This device is supported by metal bone nails or steel wires and is fixed on the finger to stabilize the fracture site. Finger external fixators can adjust the tension and angle of the brace to accommodate different types of finger fractures. 3. Finger Activation Support: This device is designed to provide the right amount of support while allowing a range of finger movement. It is usually made of a soft material such as a bandage, tape, or finger sleeve. This device can be used to stabilize finger joints, restore muscles, and increase joint mobility.

At present, most of the existing orthopedic finger recovery devices of the finger external fixator type adopt a structure with two upper and lower splints and fixed belts. This structure mainly has the disadvantages of poor adjustability and difficulty in operation. The fixation effect mainly depends on experience and techniques. Tried multiple times. For example, the Chinese utility model patent application number 201120340932.2, although this patent improves the splint into a U-shaped structure, it still does not solve the problem of the finger external fixator being difficult to adjust.

Therefore, a new type of orthopedic finger restoration device is urgently needed to provide an effective solution to the shortcomings of the existing technology.

Compared with the prior art, the beneficial effects of the present invention are:

1. When the present invention is used, a ring composed of a pair of hard splints is placed on the fracture position of the finger. After the ring is put on, the distance between the upper and lower splints at this position is adjusted by adjusting the adjustable connecting devices at the four corners. Adjusting the length of an adjustable connecting device can control the clamping strength at both ends of the splint. If the clamping strength is found to be inappropriate, it can be adjusted at any time. The invention uses a pair of universal connectors and a forward and reverse wire bidirectional adjustment screw to make the angle and distance of the connection position of the phalangeal splint adjustable, and has a simple structure and convenient operation.

2. In the present invention, the hemispherical sleeve and the ball pin limiting sleeve are configured as a detachable connection structure, which facilitates the insertion of the dry ball sleeve into the spherical space formed by the ball sleeve and the ball pin limiting sleeve. The hemispherical sleeve and the ball pin limit sleeve are assembled through the threaded connection between the external threaded port and the internal threaded port, making it easy to disassemble and assemble. The anti-slip groove can prevent slipping when twisting the ball pin limit sleeve. The circumferential outer wall of the screw sleeve is set in a regular polygonal column structure, which can prevent the ball head pin from rotating when the positive and negative two-way adjustment screw is screwed.

3. In the present invention, the flexible inner lining layer is used to protect the skin and muscles of the fingers and avoid pressure injuries. Breathable holes improve breathability.
