Embodiment approach

[0040] Place an uninflated balloon (capsule) into the subacromial space, and then inflate it, so that the balloon can press down on the humeral head, reduce the upward movement of the humeral head, restore joint mobility, and reduce pain ( figure 1 Shown is the inflation process, and the effect of the balloon on the upward movement of the humeral head during shoulder abduction).

[0041] There are several double-strand sutures around the balloon. After it is placed in the subacromial space, before or after inflation, the balloon and the surrounding tissue are fixed first, such as figure 1 The suture 3 on the inner side (right side) of the balloon can be fixed to the glenoid, rotator cuff tendon, and other structures of the scapula, and the outer side (left side) can be fixed to the humeral head and deltoid muscle. Thereby avoiding the displacement of the balloon during the movement of the shoulder joint. Sutures can be absorbable or nonabsorbable. Matched with different colo...

Abstract

The invention provides a fixable inflatable saccule, which comprises a saccule body (1); a cavity is formed in the saccule body (1); an inflatable space is formed in the inner space of the cavity; theinflatable space is communicated to the outer space of the saccule body (1) through an inflatable structure (4); the size of the inflatable space can be adjusted; the saccule body (1) is provided with a wiring part (2), and the wiring part (2) is positioned on the end face of the saccule body (1) along the thickness extension direction and / or the radial end face of the saccule body (1); the wiring part (2) is fixedly connected with the capsule body (1) or integrally formed; the wiring part (2) is provided with stitch (3), and one or more stitches (3) are arranged on the wiring part (2) in a penetrating or fixing way. According to the fixable inflatable saccule, the saccule and the surrounding tissue can be fixed before or after inflation after being placed in the lower gap of the acromion, thereby avoiding displacement of the saccule in the movement process of the shoulder joint.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a fixable inflatable balloon. Background technique [0002] The rotator cuff is a general term for the tendon tissues such as the subscapularis, supraspinatus, infraspinatus, and teres minor that cover the front, upper, and rear of the shoulder joint. Located below the acromion and deltoid muscles, it is closely connected to the joint capsule. The function of the rotator cuff is to draw the humeral head closer to the glenoid during upper arm abduction and maintain the normal fulcrum joint between the humeral head and the glenoid. Rotator cuff damage will weaken or even lose this function, seriously affecting the upper limb abduction function. Most rotator cuff injuries are caused by indirect violence. According to the degree of damage, it can be divided into partial and complete tears. The former can be divided into rotator cuff synovial lateral tear and rotator cuff synovial l...
