Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an adjustable knee joint rehabilitation device with a massage function.
Background
Along with the improvement of living standard, people pay more and more attention to their health, wherein the knee joint is regarded as a high-incidence part of diseases and receives more and more attention, the knee joint stiffness is caused by the phenomenon that the knee joint can not freely bend or straighten or severely pain is generated in the normal movement process due to the atrophy, degeneration and adhesion of the knee joint structures such as joint synovium, cartilage and the like, the knee joint stiffness limits the knee joint function of a patient and seriously affects the life and the working quality of the patient, the prior methods for treating the knee joint stiffness are divided into two types, one is surgical treatment, namely directly loosening the adhered tissues through surgery or directly prolonging the tissues such as muscle bonds of a shortened part, the other is conservative treatment represented by manual loosening and CPM machine, the principle is that external force is applied to the knee joint to slowly pull the adhered tissues apart and the metabolism of the tissues, the shortened tissues such as tendons and the like are slowly prolonged, so that the buckling function is improved, however, the surgical treatment is an invasive treatment means, new trauma and pain are brought to a patient by secondary surgery, scars and adhesion are still likely to be generated after the surgical loosening, conservative treatments such as manual loosening and CPM are still needed after the surgery, and otherwise, secondary stiffness is still caused.
