Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a knee joint post-operative straightening trainer. Background Art

[0002] Patients with knee injuries need to perform a series of rehabilitation activities after treatment. Rehabilitation training after knee surgery is very important, among which knee extension training is a commonly used rehabilitation training method. Traditional knee extension training mostly uses physical strength or gravity as an external force to assist in training. A knee extension trainer is also used. A knee extension trainer is a rehabilitation device that can help patients after surgery to perform knee extension training to restore reasonable joint mobility and daily living ability. However, general knee extension trainers often need to rely entirely on the patient's leg autonomous movement. For patients with limited knee function, the operation is difficult, the effectiveness of the training cannot be guaranteed, and there is a lack of auxiliary training devices. In addition, it is difficult to ensure the regularity and consistency of the training intensity during general knee extension training, and over-training or under-training is prone to occur, resulting in unsatisfactory rehabilitation effects for patients. For this reason, we propose a knee extension trainer to solve the above problems. Utility Model Content
