Abstract

The invention discloses a finger continuous passive motion comprising a shell body. A first traction device and a power device are arranged in the shell body. The power device is connected with the first traction device. The first traction device is connected with a finger. A second traction device is arranged outside the shell body. The second traction device is connected with the finger. The finger continuous passive motion is simple, light, low in cost, easy to manufacture, and particularly suitable for being used when a patient has a rest (especially at night).

Description

technical field [0001] The invention relates to a limb rehabilitation device, in particular to a finger continuous passive movement instrument. Background technique [0002] It is well known that the normal movement of the hand plays an important role in the daily work of human beings. The hand has complex anatomy and fine motor functions, including 21 degrees of freedom (DOF, degree of freedom), 4 DOF for each finger, and 5 DOF for the thumb. For each finger, the metacarpophalangeal joint (MP) has 2 DOF, the proximal interphalangeal joint (PIP) and distal interphalangeal joint (DIP) have only 1 DOF (the thumb metacarpophalangeal joint has 3 DOF). However, the hand is an extremely vulnerable organ, and hand injuries account for a high proportion of all traumas. About 40% of emergency surgery or orthopedic cases are hand injuries, including finger tendon and ligament injuries. In addition, stroke patients will also have finger dysfunction, which also requires long-term trea...
