| 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 issue, bone grinding experiments were conducted under saline irrigation using commercial surgical diamond wheels and it was revealed that the strong adhesion of bone swarf on the wheel surface promoted the temperature elevation at the grinding point. On the basis of the findings, new diamond wheels with fluorine-treated and porous surfaces were developed in the hopes of promptly shedding the adhesion of bone swarf on the wheel surface. These wheels significantly and stably suppressed bone temperature elevation compared to the commercial wheels.
