Taiwan currently lacks dedicated instruments for femoral head decompression surgery, with most procedures relying on curettes or imported devices that risk incomplete debridement and blade fracture. Our team developed Taiwan’s first “Smart Precision Adjustable Multi-Step Eccentric Rotational Femoral Head Debridement Instrument,” featuring multi-step eccentric expansion and a solid blade-head for precise debridement. The product has completed validation, patent transfer, and TFDA review.

This Taiwan-developed technology is designed for femoral head AVN debridement and optimized for Asian patients through medical imaging analysis. The multi-step eccentric design enables precise 11.2–17.5 mm debridement through a 10 mm minimally invasive channel. The solid blade-head design improves cutting efficiency, debris removal, and safety, overcoming the limitations of curettes and imported devices, including limited debridement range, insufficient cutting force, and blade fracture risk.

This technology is the first developed in Taiwan to address incomplete debridement, blade fracture, and the high cost of imported devices, offering advantages in precision, safety, and efficiency. The product can be integrated with PRF centrifuge kits, viscous bone injectors, and artificial bone grafts to establish a precision treatment kit with greater cost competitiveness. The technology also has applications in orthopedics, spine surgery, sports medicine, and bone tumor debridement.
