Lower limb active and passive rehabilitation training apparatus

Abstract

The invention discloses a lower limb active and passive rehabilitation training apparatus, which comprises a base, a left and right thigh supporting mechanism, a left and right calf supporting mechanism, a foot support, an external controller and two folded brackets. According to the rehabilitation training apparatus provided by the invention, an exoskeleton-type folded structure is adopted, and the simulation design of a bracket, which can fit to leg curves, can be achieved via telescopic thigh and calf supporting mechanisms in accordance with different lower limb sizes. In a transmission system, hip joints can be controlled under the driving of two stepping motors, and then ankle joints can be controlled by connecting a stepping motor to a rolling shaft screw lead. Continuous passive rehabilitation training that three joints, namely hip joint, knee joint and ankle joint, are linked can be achieved, and rehabilitation training of only the ankle joint can be achieved via the stepping motor. The rehabilitation training apparatus provided by the invention serves for a patient that lower limb needs to undergo rehabilitation training; and active and passive modes are combined, so thatdoctors are facilitated in objective rehabilitation assessment; therefore, the rehabilitation training apparatus is conducive to improvement and confirmation of a treatment scheme.

Description

Technical field [0001] The invention relates to a rehabilitation training device, in particular to an active and passive rehabilitation training device for lower limbs. Background technique [0002] The joint function rehabilitation device is an orthopedic rehabilitation medical device, based on the theory of continuous passive motion (that is, CONTINUES PASSIVEMOTION, CPM for short). By simulating the natural movement of the human body, it stimulates the natural recovery of the human body, exerts the compensatory effect of tissue, and performs the function of lower limb joints Rehabilitation training is safe and practical in clinical application, pain-free, patient willing to accept, large joint range of motion, effective elimination of joint adhesion and necrotic joint survival, wound healing and swelling, promotion of self-repair of articular cartilage damage, and conducive to grafting periosteum transformation The advantages of hyaline articular cartilage. [0003] At present,...

AI Technical Summary

Problems solved by technology

[0003] At present, most CPM machines cannot perform joint training of the three joints of the hip, knee and ankle at the same time, which has certain limitations and is not conducive to the rehabilitation training of the three joints of the lower limbs; in addition, most CPM machines mainly focus on passive training, and active training is not added; At the same time, the lower limb training lacks real-time feedback, and the evaluation cannot be quantified; it is bulky, inconvenient to move, time-consuming and laborious, and brings a lot of inconvenience to patients and medical staff.
