Technology Overview

During sports activities, joint and soft tissue injuries often require surgical fixation. However, traditional solid bone screws used in tissue repair have poor integration with surrounding tissues after implantation, which may lead to inflammation and loosening.

This technology leverages the advantages of 3D printing to integrate the mechanical strength requirements of various anatomical sites with biological healing needs. It features a hybrid bionic design that combines a solid support structure with a three-dimensionally interconnected porous architecture. This design enhances fixation stability, promotes faster integration and regeneration between soft and hard tissues after injury, and enables earlier rehabilitation, reducing the need for additional medical intervention.

Technical Superiority

1. The special flexibility and microporous structure enhance shock absorption and bone integration, addressing current clinical issues such as poor soft–hard tissue integration, prolonged healing periods, stress-induced fracture or loosening, and post-implantation inflammation.

2. Laser powder bed fusion (LPBF) additive manufacturing enables the production of bionic mini bone screws with controllable three-dimensionally interconnected porous structures.

3. Supports customized implant designs, increasing flexibility and adaptability for clinical applications.

Application

1. Applicable to clinical treatment of shoulder, hip, and knee joint disorders.

2. Bionic bone screws are widely used in orthopedics, dentistry, and aesthetic medicine, especially for elderly patients or those with osteoporosis.

3. Future development may incorporate functional composite and degradable materials, such as drug delivery or cell-based therapies.
