[0002] In the field of pediatric cardiothoracic surgery, minimally invasive cardiac surgery has become an increasingly important treatment for congenital heart disease due to its advantages of minimal trauma and rapid recovery. However, the postoperative rehabilitation phase is crucial for the recovery of cardiopulmonary function, the restoration of motor skills, and psychological adaptation in children. Currently, common postoperative rehabilitation methods in clinical practice mainly include physical therapy, breathing training, and progressive exercise guidance. Children are in their growth and developmental stages, and their physiological and psychological characteristics place higher demands on rehabilitation training. Postoperative rehabilitation requires real-time monitoring of key indicators such as heart rate, blood oxygenation, and respiration. However, traditional methods rely on manual recording or single sensors, with limited data integration and analysis capabilities. Children have weak mobility and self-control, and improper movements during training may lead to wound stretching or instrument damage. Patients after cardiac surgery need to remain in bed for extended periods, which can lead to stiffness, poor blood flow, and muscle pain. Patients require rehabilitation nursing training. Existing upper limb training for patients relies primarily on medical staff, increasing their workload. Therefore, we designed a postoperative rehabilitation training device for minimally invasive cardiac surgery in pediatric cardiothoracic surgery. Summary of the Invention
