Description

Technical Field

[0001] The present invention relates to a rotator cuff interval release device and method. Background Art

[0002] The rotator cuff interval is the interval between the coracoid process of the shoulder joint and the humerus. The tissues within the rotator cuff interval are complex. If the rotator cuff interval is too narrow, there will be insufficient space, resulting in impingement of the tissues attached to the coracoid process and the humeral head.

[0003] The impingement of the coracoid process and the tissues around the rotator cuff interval is not only an assessment content for shoulder pain but also the core of various shoulder pain treatments. Currently, there is no treatment assistance device for the impingement of the tissues around the coracoid process and the rotator cuff interval after it becomes too narrow. Therefore, the present invention designs a portable and wearable rotator cuff interval release device. Summary of the Invention

[0004] To solve the defects of the prior art, the present invention provides a rotator cuff interval release device, including: an elastic arm band for tightly sleeving on the upper end of the affected upper arm of the patient, a wearable fixing device for fixing on the upper body of the patient, a rigid outward pulling arm with one end fixedly connected to the wearable fixing device and used for surrounding the upper end of the affected upper arm of the patient, a backward pulling strip with one end fixedly connected to the rigid outward pulling arm and the other end used for hooking the elastic arm band and pulling the upper end of the affected upper arm of the patient in the backward extending direction, a lateral pulling strip with one end fixedly connected to the rigid outward pulling arm and the other end used for hooking the elastic arm band and pulling the upper end of the affected upper arm of the patient in the abduction direction, and a rigid inward fixing arm with one end movably connected to the wearable fixing device and used for clamping the lower end of the affected upper arm of the patient.

[0005] The present invention also provides a rotator cuff interval release method, using the above release device to release the rotator cuff interval.
