| Outline of Final Research Achievements |
Existing surgical technologies are unable to prevent thermal injury to adjacent tissues such as nerves that result from grinding heat generated during bone resection. To address this problem, bone grinding experiments were conducted under irrigation using commercial surgical diamond wheels to clarify the grinding characteristics. On the basis of the findings, new diamond wheels coated smoothly with submicron-sized titanium dioxide particles were developed. The developed grinding wheels significantly suppressed bone temperature elevation during grinding compared to the commercial wheels.
