Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical traction equipment, and particularly relates to a cerebral palsy traction treatment device. BACKGROUND

[0002] Cerebral palsy is a motor disorder caused by damage to the developing brain, and its typical symptoms include abnormal muscle tone, muscle spasm and limited joint movement. Traction treatment is a common and effective method for relieving muscle spasm, increasing joint movement and preventing contracture deformity in rehabilitation medicine. Traditional traction equipment is driven by a motor or manually operated mechanically, which has some limitations in clinical application, and cannot intelligently and safely adapt to the sudden and involuntary body movement of cerebral palsy patients due to spasm, and has certain risks and inconvenience.

[0003] (1) When the patient produces strong resistance and retraction due to pain or sudden muscle spasm, the existing traction equipment cannot automatically identify and immediately stop traction, resulting in uncontrolled traction force, which may cause discomfort and fear of the patient, and may even cause secondary injury to the muscle or soft tissue, and the safety needs to be improved.

[0004] (2) After many devices complete traction or trigger safety stop, the doctor needs to manually reset or set up a complex program for the next treatment, which not only increases the workload of the therapist, but also prolongs the overall time of single treatment, and reduces the diagnosis and treatment efficiency.
