Ankle joint training device

Abstract

The invention provides an ankle joint training device. The ankle joint training device comprises a base, and a driving device, a transmission device, a foot support and a rotary table which are arranged on the base, wherein a sliding rail is arranged on the rotary table in the radial direction; the sliding rail is matched and provided with a sliding block capable of sliding on the sliding rail; the sliding block is connected with the front end of the foot support through a ball universal joint; the foot support comprises a rectangular framework main body and a foot placing plate; the rectangular framework is located between two fork arms of a fork-shaped bracket; a copper sleeve supporting rod is further fixed between the two fork arms of the fork-shaped bracket; a copper external member is arranged on the copper sleeve supporting rod in a sliding manner; the copper external member comprises a U-shaped steel frame and an I-shaped wheel copper sleeve; an inner shaft of the I-shaped wheel copper sleeve is embedded into a U-shaped groove of the U-shaped steel frame; the lower side of the U-shaped steel frame is arranged on the copper sleeve supporting rod in a penetrating manner and can slide leftward and rightward along the copper sleeve supporting rod; a guide rod is connected and arranged between front and rear ends of the foot placing plat of the foot support, and a vertical connecting rod connected with the rectangular framework; the guide rod is arranged in the I-shaped wheel copper sleeve in the penetrating manner; the guide rod is in sliding connection with the I-shaped wheel copper sleeve in the axial direction. The device can help a patient to do a whole set of ankle joint rehabilitation movement including ankle joint flexion and extension movement, ankle joint lateral movement, ankle joint rotary movement and the like.

Description

technical field [0001] The invention relates to a joint training device, in particular to an ankle joint training device, belonging to the technical field of medical devices. Background technique [0002] The ankle joint is the main load-bearing structure and motion joint of the human body. In daily life and sports, ankle joint injuries are common bone and joint injuries. Other diseases, such as it, are also one of the most vulnerable joints in the human body. In some other diseases, such as traumatic brain injury, stroke, nerve injury, etc., long-term inactivity of the ankle joint will cause joint adhesion, long-term pain, and inconvenient walking. With similar levels of other motor function in the lower extremity, the higher the ankle motor score, the better the patient's walking ability. Therefore, the ankle joint movement function of patients can be used as a main index to evaluate the rehabilitation efficacy of patients with stroke, traumatic brain injury, bone injury,...

AI Technical Summary

Problems solved by technology

Existing ankle joint rehabilitation devices usually have only 1 to 2 degrees of freedom, and the rehabilitation training mode is single, which is difficult to fit the ankle joint movement during the exercise process, and the range of motion is fixed and single, which cannot be adjusted according to the specific condition of the patient
