Rotator cuff balloon

Abstract

The invention discloses a rotator cuff balloon. The rotator cuff balloon comprises a limiting structure and a protection structure connected to the limiting structure. The limiting structure has an arc along the coronal plane. The prosthesis conforms to the physiological structure of the shoulder joint of the human body, is limited to the subacromial space, and can reduce adverse events such as foreign body sensation, dislocation and functional failure of a patient. The prosthesis conforms to the physiological structure of the shoulder joint of the human body, is limited to the subacromial space, and can reduce adverse events such as foreign body sensation, dislocation and functional failure of a patient.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a rotator cuff balloon. Background technique [0002] The rotator cuff is the muscle-tendon structure that connects the scapula to the head of the humerus and is located on the outer layer of the shoulder joint capsule and the inner layer of the deltoid muscle. The rotator cuff is composed of anterior rotator cuff (subscapularis), upper rotator cuff (supraspinatus), and posterior rotator cuff (infraspinatus and teres minor). The main function is to stabilize the position of the humeral head on the glenoid, avoiding pain caused by the humeral head moving up and hitting the acromion. Therefore, the rotator cuff plays an extremely important role in maintaining the stability of the shoulder joint and in the process of shoulder joint movement. However, with age, long-term repeated shoulder joint activities, subacromial bone hyperplasia, or repeated strenuous activities may cause wear ...

AI Technical Summary

Problems solved by technology

Prosthetic implants in the prior art, such as prosthetic devices, biogaskets, etc., may be displaced during patient activities. For example, the displacement of the prosthetic device may cause pressure distribution to change, causing the prosthesis to rupture, and long-term The degenerated content at 37° is released, causing further damage to the affected area, and the injection hole has hard material, which may cause discomfort and foreign body sensation to the patient under certain actions after implantation

Migration of the biospacer can cause discomfort, limitation of motion, or even damage to surrounding soft tissue, causing further injury

In addition, prosthetic implants in the prior art may fail
