Abstract
Rehabilitation of lower limb CPM devices are also known as the continuing rehabilitation activities, and it is used to help patients with knee joint replacement surgery, patients with lower limb rehabilitation to restore the joint function of a machine.
In this paper, the characteristics of CPM rehabilitation devices and applications. Designed to end joint rehabilitation CPM rehabilitation, and the plane through the motor output power, the rotation of ball screw drive to drive. In this paper, the main bar by the force conducted a stress analysis and calculation. Check the motor power, the life of bearings and sales. The total assembly drawing, telescopic rod, shaft, such as engineering drawings.
Rehabilitation of the CPM structure is simple, compact, smooth drive.
