Hammer finger orthopedic appliance

Abstract

The invention relates to a hammer finger orthopedic appliance which comprises a finger tip rest and a near-end finger rest. The finger tip rest comprises a front finger tip rest protector and a first hinge portion positioned at the tail end, the near-end finger rest comprises a front second hinge portion and a middle section rest protector positioned at the tail end, the first hinge portion and the second hinge portion are connected in a hinged manner and rotate along the extending and retracting direction of fingers, the first hinge portion is provided with an angle adjusting mechanism for driving the finger tip rest to rotate around a hinge point, and the angle adjusting mechanism is provided with an operating end and a driving end and is a unidirectional locking angle adjusting mechanism with the operating end unidirectionally transmitted to the driving end. The finger tip rest and the near-end finger rest are hinged in design and matched with the angle adjusting mechanism, the hammer finger orthopedic appliance more effectively adapt to hammer finger orthopedics of different people, and rehabilitation effects of patients are improved.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, specifically, a hammer finger orthosis for treating hammer fingers. Background technique [0002] Hammer-shaped refers to the rupture of the extensor tendon near the stop point, and the distal phalanx cannot be straightened, often combined with avulsion fractures on the dorsal side of the distal phalanx, such as figure 1 Shown are hammer fingers. [0003] At present, the treatment of mallet fingers uses internal fixation and external orthosis. Because the phalanx for mallet finger pathology is small, the surgical operation of internal fixation is inconvenient. Hammer fingers for treatment. The existing external orthoses on the market are also called finger rests, including finger rests for holding up and fixing finger tips 1-1 and proximal finger rests for holding proximal knuckles 1-2 connected to finger tips 1-1. The finger rest and the proximal finger rest are integrally formed, and...

AI Technical Summary

Problems solved by technology

External orthotics on the existing market are also called finger rests, which include a finger rest that supports and fixes the fingertips 1-1 and a proximal finger rest that is connected with the proximal knuckles 1-2 that are connected to the fingertips 1-1. The fingertip rest and the proximal finger rest are integrally formed, and the bending angle between the fingertip rest and the proximal finger rest is not adjustable. Usually, the finger rest supports the fingertips and the proximal knuckles in a straight state, but the actual The warping angle of the fingertips of different people is different, and the uniform straight fixed orthopedic method will have a poor orthopedic effect for patients with a large fingertip warping angle, which is not conducive to the rehabilitation of the patient.
