Sugita教授の研究室では、手術中の生体組織、特に皮質骨における熱傷の発生を防止するための熱伝導解析と温度予測モデルの構築を主眼としています。特に人工関節置換術におけるドリルやキリによる骨切りの際の温度上昇を理論的・実験的に解明し、手術の安全性向上を目的としています。熱的ストレスが骨細胞に与える影響を評価するための高精度な熱モデル開発が進んでいます。

Living bone must be cut before performing arthroplasty. For example, the distal part of the femur and the proximal part of the tibia must be cut to perform total knee arthroplasty. Osteocytes begin to necrose when the cutting temperature during such procedures exceeds 50 degrees C. In this study, the temperature distribution inside bone was calculated theoretically using a linear heat source moving on a semi-infinite plane. Moreover, the temperature distribution on the surface layer of the cutti
This paper provides a methodology to develop a thermal model for predicting the temperature rise during surgical drilling of bone. The thermal model consists of heat generation calculation based on classical machining theory and development of governing equations of heat transfer individually for drill bit and bone. These two governing equations are coupled by shared boundary conditions. Finite-difference method is utilized to approximate the thermal model and effects of drill bit geometry and p
