Description

A stress measurement traction system

Technical field

The invention relates to the technical field of medical equipment, and in particular to a stress measurement traction system.

Background technique

Joint stiffness refers to the varying degrees of impairment of normal joint function, which is manifested by a reduction in the range of joint motion. Joint stiffness is generally treated with physical therapy, external application of traditional Chinese medicine, joint function exercisers, and manual release. It can even be treated through surgery. Most people are willing to accept non-surgical conservative treatment. The conventional method is to use joint functional exercisers. The method is to use a brace to traction the joint. The brace maintains a predetermined angle every day, forcing the soft tissue of the joint to plasticize, so that the joint can flex and extend at different angles. Maintain for different periods of time to allow the soft tissue of the joint to return to or close to normal levels.

Currently, the mainstream traction braces only use mechanical structures to maintain the joints at the flexion and extension angles set by the doctor, thereby utilizing the stress relaxation effect of the joint soft tissues for treatment. Among them, the stress relaxation effect of soft tissue refers to the phenomenon that the soft tissue remains motionless after being stretched to a certain length. As time goes by, the internal tension of the tissue will gradually decrease. This effect can cause permanent deformation of the soft tissue of the joint, thereby healing the joint. stiff.

Existing traction braces still have the following shortcomings: during the treatment process, medical staff can only indirectly judge the degree of stress relaxation of the soft tissue based on the flexion and extension angle set by the brace, and then determine whether the permanent deformation of the soft tissue has been in place and whether it can be ended. Treatment course, but the process of permanent deformation of soft tissue under the traction of the brace is non-linear. Due to the inability to effectively monitor the amount of soft tissue deformation (that is, the degree of stress relaxation), the formulation of the treatment plan is not accurate and personalized enough, resulting in the treatment course being based on weeks. , the time span is large, which leads to over-treatment or under-treatment, causing the treatment to fail to achieve the set goals and even causing secondary harm.
