A rotator cuff balloon (10). The rotator cuff balloon (10) comprises a limiting structure (100) and a protective structure (200) connected to the limiting structure (100); and the limiting structure (100) is provided with an arc along a coronal plane. The rotator cuff balloon (10) conforms to the physiological structure of the shoulder joint of a human body, is limited to the subacromial space, and can reduce adverse events such as foreign body sensation, dislocation and functional loss from occurring to a patient. |
