Abstract

The invention discloses a knee joint training device. The knee joint training device comprises a supporting frame, a power device, two thighbone fixing plates and two tibia fixing plates, wherein thepower device is installed on the supporting frame, the two thighbone fixing plates are connected through a fixing plate connecting frame, and one thighbone fixing plate is fixedly connected with the supporting frame. The two tibia fixing plates are located between the two thighbone fixing plates, and are connected with the thighbone fixing plates through connecting rods, and the connecting rods penetrate through the tibia fixing plates and the thighbone fixing plates. One tibia fixing plate is connected with the power device through a transmission rod; Arc-shaped grooves are formed in the twothighbone fixing plates, idler wheels are installed at the two ends of each connecting rod, and the tibia fixing plates make concentric rotational motion relative to the thighbone fixing plates. The thighbone fixing plates are fixed to the thighs of a patient, the tibia fixing plates are fixed to the shanks of the patient, the rotation center of the device is adjusted to be aligned with the knee joint rotation center of the patient, thus knee joint movement is formed, and the aim of training the functions of the knee joints is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical rehabilitation equipment, and relates to a knee joint training device. Background technique [0002] In the past, the knee joint exerciser only performed knee flexion and extension exercises, without considering the abnormal surface speed of the joint surface during the movement of the knee joint caused by the poor matching of the center of rotation, forcing some parts of the joint surface to be tightly pressed, while others A part of the separation increases surface friction and mechanical wear, which increases the patient's pain and is not conducive to the recovery of knee joint function. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the object of the present invention is to provide a knee joint training device, which avoids the problems of surface friction and mechanical wear of the knee joint during activities caused by poor rotation ce...
