AI Technical Summary

Technical Problem

Existing rib fixation devices are difficult to effectively fix during minimally invasive surgery and are complicated to operate, resulting in large surgical wounds and affecting patient recovery.

Method used

A self-locking rib fracture fixation device was designed. Through the cross-arranged connecting parts and the rotation locking parts, the clamping fixation hook group and the locking protruding tooth structure are used to achieve stable fixation of the ribs, and the rotation adjustment and locking are completed in vitro through a special operating instrument.

Benefits of technology

It achieves efficient and stable rib fixation under minimally invasive surgical conditions, reduces surgical incisions, improves the accuracy and simplicity of operation, and shortens operation time.
