Device for treating massive rotator cuff tear

Abstract

The invention discloses a device for treating massive rotator cuff tear. The device comprises a pressurizing device, a high-pressure tee device, a handle device and a saccule device, wherein the pressurizing device, the high-pressure tee device, the handle device and the saccule device are sequentially connected. According to the device disclosed by the invention, an upper joint capsule reconstruction principle is utilized; a saccule structure is adopted to replace autologous tendon or allogeneic tendon, and is used for treating the massive rotator cuff tear, especially supraspinatus muscle and tendon tear; the saccule is stuffed between the head of humerus and the acromion to replace the torn tendon, so that the situation that the head of humerus impacts the acromion to generate violent pain is avoided, and the spherical mesh structure of the rotator cuff is repaired; the saccule can be produced in batch, so that the problem that the source of the autologous tendon or the allogeneic tendon is not sufficient is solved; the device can be used for open type operations, and can also be used for minimally invasive arthroscope operations; when the device is used in the minimally invasive arthroscope operations, the operation wound of a patient can be greatly alleviated, and the operation recovery time of the patient is reduced; and the device is easy to operate and easy to use clinically.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a device for treating huge rotator cuff tear. Background technique [0002] The shoulder joint is a ball-socket joint formed by the head of the humerus and the shallow glenoid. Four muscles, the supraspinatus, infraspinatus, teres minor, and scapula, converge in the form of tendons that wrap around the humeral head to form a spherical network called the rotator cuff. The function of the rotator cuff is to keep the head of the humerus within the glenoid. The rotator cuff attaches the humerus to the scapula and plays a very important role in the normal movement of the shoulder joint. When one or more rotator cuff tendons are torn, the tendons no longer fully attach to the humeral head. Most tears occur in the supraspinatus muscle and its tendon, but other parts of the rotator cuff may also be torn. In many cases, a tendon tear begins with abrasion, and as the damage progresses,...

Problems solved by technology

[0005] (1) If the autologous tendon is used, it is necessary to cut the tendon from other parts of the patient. The operation is very complicated, the operation trauma is large, and the patient's recovery time is long
