Description
Technical Field
The utility model belongs to the technical field of rehabilitation medical instruments, relates to rehabilitation training of a patient after a knee joint operation, and particularly relates to a knee joint operation rehabilitation training device.
Background
At present, the clinical rehabilitation training mode for the knee joint operation of a patient mainly comprises three types: 1. a knee joint continuous passive motion instrument is adopted to assist the knee joint to move passively; 2. assisting the patient to perform rehabilitation training through a rehabilitation teacher or family members; 3. the patient carries out rehabilitation training by himself. However, these three approaches all have certain drawbacks:
first, adopt the knee joint to last the passive motion mode of appearance assistance knee joint passive motion
The knee joint continuous passive activity instrument with the existing structure can only provide rigid and passive rehabilitation training for a patient, and the knee bending motion frequency of the patient is large and the duration time is long when the rehabilitation training is carried out, so that the patient is easy to feel uncomfortable, the knee joint of the patient is seriously swollen even, and secondary damage is caused to the knee joint of the patient;
meanwhile, the passive movement of the instrument cannot meet the requirement of muscle strength training of the lower limbs of the patient, the muscle strength of the patient is not enough to exercise, a backward state may occur after the patient is discharged, and the rehabilitation training effect is not good;
moreover, the knee joint continuous passive motion instrument is expensive, only a special hospital can be equipped correspondingly, and the instrument is not suitable for the patient to purchase and use by himself. Therefore, this method can be performed only during hospitalization and cannot be extended to rehabilitation training after patient discharge.
Second, the rehabilitation training mode is assisted by the rehabilitation teacher or family members
