X-shape retractor for musculus subscapularis

Abstract

The invention discloses an X-shape retractor for musculus subscapularis. The retractor comprises a sliding rod, an outer sleeve and a retractor assembly; the outer sleeve sleeves the sliding rod, theretractor assembly is arranged in a gap between the sliding rod and the outer sleeve, and one end of the retractor assembly is fixed to the sliding rod; when the outer sleeve is pulled out along the sliding rod, the other end of the retractor assembly is raised outward to expand the musculus subscapularis. According to the X-shape retractor for the musculus subscapularis, through the cooperation among the sliding rod, the outer sleeve and the retractor assembly, the process of coracoir expansion is simplified, correspondingly the operation time is shortened, and the operation effect is improved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and equipment for operation, and in particular relates to a spreader for the subscapularis muscle. Background technique [0002] In the process of subscapularis surgery, the cut coracoid process needs to be fixed in the glenoid bony defect area of ​​the shoulder joint; the existing special instruments for this process are cumbersome to use, and need to be positioned and pierced through the arthroscopic exchange rod first After the subscapularis, conventional arthroscopic instruments are used in front to widen the piercing exit. The process is recurrent and inefficient, which makes it slow and difficult to fix the coracoid process in the proper position of the glenoid under the microscope; If the lower muscle is separated, a little carelessness will touch or injure important surrounding blood vessels and nerves, which will affect the final surgical effect and even endanger the patient's...
