Glenoid cavity prosthesis system

The invention discloses a glenoid cavity prosthesis system which comprises a glenoid cavity prosthesis main body and is characterized in that three threaded holes are formed in the side face of the glenoid cavity prosthesis main body, the three threaded holes are distributed in a triangular shape, a fixing screw is detachably connected into each threaded hole, and the glenoid cavity prosthesis main body is connected with the glenoid cavity prosthesis main body. The fixing screw is used for fixing the glenoid cavity prosthesis main body and a bone of a patient; the glenoid cavity prosthesis system further comprises a dismounting and mounting assembly used for mounting the fixing screw. The dismounting and mounting assembly comprises a drilling assembly and a fixing assembly. The drilling assembly comprises a sleeve and a guide pin, the guide pin is arranged in the sleeve in a sliding mode, and a depth limiting ring is arranged at the position, close to the tail end, of the guide pin. According to the glenoid p
