A new surgical grinding wheel for suppressing grinding heat generation in bone resection

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 with submicron-sized titanium dioxide particles were developed to enhance the hydrophilicity of the wheel surfaces. The developed grinding wheels significantly suppressed bone temperature elevation during grinding compared to the commercial wheels.
