Problems solved by technology
[0003] Most of the existing finger rehabilitation devices use to drive the patient’s distal knuckles, while the middle knuckles and metacarpophalangeal joints are not restrained, causing the patient’s fingers to deform during the finger rehabilitation exercise, reducing the rehabilitation effect, and even when the fingers are deformed. Smaller tension during rehabilitation training will strain the patient's four fingers

The invention provides a two-joint traction finger rehabilitation trainer. The two-joint traction finger rehabilitation trainer comprises a palm support, wherein a motor is fixed on the palm support, a motor output shaft is provided with a first crank, the first crank is connected with a first connection rod through a hinge, the other end of the first connection rod is connected with a second crank through a hinge, and the second crank is horizontally placed in an L shape. A metacarpophalangeal joint frame is fixed on the second crank, four metacarpophalangeal joint fixing sleeves are fixed on the metacarpophalangeal joint frame, the second crank is connected with a second connection rod through a hinge, the second connection rod is horizontally placed in an L shape and is connected with a rocker through a hinge, the rocker is connected with the palm support through a hinge, a far-end finger joint frame is fixed on the second connection rod, and four far-end finger joint fixing sleeves are fixed on the far-end finger joint frame. The two-joint traction finger rehabilitation trainer is composed of two hinge four-rod mechanisms, is driven by the single motor, and is simple in structure.
Description
1. Technical Field [0001] The invention relates to a rehabilitation training device for two-joint traction fingers, belonging to the field of rehabilitation medical equipment. 2. Background technology [0002] With the gradual aging of our country’s population, the pollution and deterioration of the living environment, and the acceleration of the pace of life, stroke patients are increasing year by year, and are showing a trend of youthfulness. At the same time, the increase in various means of transportation and the rapid development of industry have caused brain trauma, hand injury The number of trauma patients is also increasing. Rehabilitation training plays a vital role in the compensation and reorganization of patients' cranial nerves. [0003] Most of the existing finger rehabilitation instruments use to drive the patient’s distal knuckles, while the middle finger joints and metacarpophalangeal joints are not restrained, causing the patient’s fingers to deform during the fin...
