| 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 focusing on the adhesion and shedding of bone chips on wheel surface.
On the basis of the findings, new diamond wheels with a hydrophilic-treated surface and a cool air supply method were developed for making a gas single-phase or liquid single-phase state near the grinding point. The wheels and cooling method significantly and stably suppressed bone temperature elevation compared to the commercial wheels.
