Description

Balloon for directionally expanding joint cavity under ultrasound to treat frozen shoulder Technical Field The utility model relates to the technical field of medical treatment, in particular to a balloon for treating frozen shoulder by directionally expanding a joint cavity under ultrasound. Background Adhesive shoulder joint capsulitis (adhesivecapsulitis, AC) lesions involve the glenohumeral joint capsule, the main pathological basis of which is joint capsule fibrosis thickening, imaging is mostly joint capsule contracture, and joint volume is reduced. The current methods for treating AC mainly comprise analgesia, physical therapy, intra-articular injection, loosening under anesthesia, loosening under arthroscope and the like. The intra-articular injection of steroid hormone under ultrasonic guidance can relieve inflammatory reaction in joint cavities, pain, and better clinical effect can be achieved by assisting rehabilitation training. Rehabilitation training can be completed under ultrasonic monitoring as well, and by utilizing the advantages of ultrasonic dynamic evaluation, a doctor can dynamically monitor the shape and thickness of the joint capsule in real time, so that the effective stretching position of the shoulder capsule can be determined. Physiological saline can be injected into the joint under the guidance of ultrasound, and the purpose of treatment can be achieved by hydraulically expanding contracture joint capsules. In addition, recent studies have shown that joint extracapsular fascia release under ultrasound guidance is an effective, less invasive treatment, and they use saline to release thickened extracapsular fascia tissue under ultrasound guidance, and have found that the improvement in mobility after the procedure is not limited to supination, but also includes flexion, extension, abduction, and the like, possibly because the release of fascia tissue affects surrounding muscles, thereby improving mobility in all directions. Meanwhile, there are also studies on treatment of AC through suprascapular nerve block, and it was found that the proximal access to the suprascapular notch through the hyoid muscle of the shoulder better reveals the suprascapular nerve, thereby improving injection accuracy. However, although the above methods have certain feasibility and rationality, there are some drawbacks. Intra-articular injection of steroid hormones under ultrasound guidance has proved to be useful for treating AC, but requires rehabilitation training, is not suitable for patients with overthick axillary sacs, and has a certain possibility of damaging rotator sleeves, and intra-articular injection of physiological saline physically expands or releases the intra-articular sacs, so that directional expansion of the articular sacs cannot be achieved due to the action of gravity of liquid and the like. Therefore, the utility model aims to provide a balloon for directionally expanding a joint cavity under ultrasonic to treat frozen shoulder so as to expand the joint cavity and loosen the joint cavity, so as to make up for the defects of the technology. Disclosure of utility model The utility model aims to provide a balloon for directionally expanding a joint cavity under ultrasound to treat frozen shoulders, and the balloon is used for working, so that the problems are solved. In order to solve the technical problems, the balloon for treating frozen shoulder by using the joint cavity is provided with the following technical scheme that the balloon comprises a puncture guide needle, a first-size balloon main body and a second-size balloon main body, wherein the first-size balloon main body is arranged on the outer side of the top of the puncture guide needle, the second-size balloon main body is arranged on the outer side of the bottom of the puncture guide needle, the second-size balloon main body is positioned below the first-size balloon main body, a first-size balloon inflation port is formed in the side wall of the top of the puncture guide needle, the first-size balloon inflation port is communicated with the interior of the first-size balloon main body, a second-size balloon inflation port is formed in the side wall of the bottom of the puncture guide needle, the second-size balloon inflation port is communicated with the interior of the second-size balloon main body, the second-size balloon inflation cavity is formed in the left side of the puncture guide needle, and the first-size balloon inflation cavity is formed in the right side of the puncture guide needle, and the first-size balloon inflation cavity is communicated with the first-size balloon inflation port.
