AI Technical Summary

Technical Problem

In existing in vitro biomechanical experiments of the shoulder joint, the humeral clamp has limitations such as limited clamp freedom, inability to integrate muscle loading, poor adaptability, and lack of modular design, resulting in low experimental efficiency, inconsistent results, and a high risk of soft tissue injury.

Method used

A modular humeral clamp system is designed, which adopts a unified clamp base, integrates fixed and flexible tooling modules, and combines a pneumatic loading module to achieve rapid module interchange and muscle loading integration. It is connected to the base through a standardized mechanical interface, adapts to humeral specimens of different diameters, and synchronizes muscle loading and movement.

Benefits of technology

It improves experimental efficiency, reduces the risk of specimen loss, enhances adaptability and accuracy of experimental results, achieves precise synchronization between muscle loading and motion trajectory, and supports simulation of complex working conditions.
