Femoral head necrosis repair trainer and bicycle

Abstract

A femoral head necrosis repair trainer comprises a base frame, a cushion arranged on the base frame, a damping pedaling device fixed to the base frame and arranged in front of the cushion, a pedal connected to the power end of the damping pedaling device, and angle-adjustable supporting plates arranged on the two sides of the cushion and used for supporting the roots of thighs. The damping pedaling device comprises a rotating shaft and two flywheels with damping, the two flywheels are connected to the two ends of the rotating shaft and are symmetrically arranged, the included angles between the moving planes of the flywheels and the rotating shaft on the sagittal plane and the coronal plane range from 10 degrees to 20 degrees, and the pedals are connected to the flywheels. The trainer provided by the invention can provide a motion mode for limiting a fixed angle and a special mechanical motion trail favorable for grinding a femoral head to repair a sphere; the hip joint inner head acetabulum relation matching of a patient is promoted, continuous and effective rehabilitation is achieved, muscles and ligaments around femoral head necrosis can be adjusted and repaired in a wide range,the overall structure is simple, and use is convenient.

Description

Technical field [0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a training device and a bicycle for repairing femoral head necrosis. Background technique [0002] Femoral head necrosis is a refractory disease. It is characterized by discomfort in the hip, and eventually collapse of the articular surface, resulting in increased pain, and limited internal rotation during lower limb activities. The existing treatment methods usually include femoral head necrosis, revascularization, Interventional therapy and packet therapy, etc., but these treatments are mostly invasive treatments with poor efficacy. In addition, some patients with femoral head necrosis can also be treated with oral medications, but the patient’s hip joint movement function will still be limited, and the long-term immobilization of the hip joint can easily lead to disuse atrophy of the hip muscles and Contracture deformation of ligaments. The necrosis often...
