[0002] The symptoms of shoulder joint wear are related to the location and severity of the injury. The overall symptom is pain. For example, biceps tendon injury mainly causes tenderness in the shoulder joint, and severe pain occurs when the shoulder is lifted or held. In the shoulder joint prosthesis, a balloon is set between the acromion and the humeral head to replace the subacromial bursa of the shoulder joint. In order to know the service life of the balloon in the human implant shoulder joint prosthesis, wear testing tooling is generally required to perform wear testing.

However, when the existing shoulder joint wear test tooling is installed on the humeral head prosthesis, most of the time, manual observation is required to see whether it corresponds to the balloon, and the positioning and installation efficiency is low, which affects the test efficiency.
