[0002] The wrist joint is a wearable device specially equipped for patients with hip joint injuries and other exoskeleton lower limb activity disorders. It is a unique design based on the combination of human anatomical structure and sports physiological curves. It simulates the natural movement of the human body, stimulates the natural resilience of the human body, and restores the function of the joint to the greatest extent, so that the recovered joint can move freely, thereby improving the patient's quality of life. The wrist joint continuous passive training system performs continuous passive training on the patient's wrist. It can achieve full joint activity range of flexion, extension, ulnar and radial deviation separately or simultaneously. It is durable and lightweight, with little burden on the patient, and the reverse function in case of resistance ensures the safety of the patient. It has good effects on distal radius fracture rheumatoid, joint stiffness caused by neurosis or burns, sympathetic nerve reflex disorder, etc.

[0003] Fig. 9 It is a schematic diagram of the appearance structure of an existing wrist joint rehabilitation device, and the product mainly consists of a base plate 24, a transmission mechanism 22, a sheet metal casing 23, a plastic casing 20, and a handle 21.

[0004] The bottom plate 24 is used to fix and support the transmission part, the transmission mechanism 22 is the core mechanical structure of the equipment, the sheet metal housing 23 is used to install the electronic control components, the handle 21 is the patient's hand holding part, the bottom of the bottom plate 24 has a foot pad for supporting the equipment and anti-skid, the transmission part is a motor driving the lead screw and slider to drive the movement of each connecting rod; the sheet metal housing 23 is provided with a circuit board, a touch screen, and a transformer. The existing wrist joint rehabilitation equipment motor drive circuit drives the finger joint trainer components for passive training, and the maximum angle of activity is -50° downward and 60° upward. During the movement of the trainer, the motor will output a sine signal, convert the sine signal into a square wave (the process of converting from a sine wave to a square wave is the function of the speed detection circuit), and the speed of the motor movement is detected by the square wave to adjust the speed of the machine.
