Abstract
Background: In recent years, the researches and developments on skull grinding to remove bone pathology are increasing. Clinically, the neurosurgeons usually treat skull based lesions by removing bone pathology with high speed grinding wheel. Nevertheless, high speed grinding produces a large amount of heat, which causes thermal damage to surrounding tissues and bone necrosis. The highest critical temperature of thermal damage is 43°C. In addition, the grinding force is a key factor to determine the success of the surgery.
Objective: Too large or too small grinding power is unable to give ideal operation effect. At present, the clinical doctors can't detect and control the temperature and force in skull grinding operation.
Methods: The goal of this work is to solve the urgent problem by summarizing patents on skull grinding equipments.
Results: Qingdao Technological University research team carried out the studies on skull grinding equipments. Among these patents, one is the online detection and controllable hand-held grinding device. It can adjust the speed of grinding wheel through monitoring acoustic emission signal, thereby reducing the grinding temperature. The medical surgical operation 6-degree-of-freedom automatic adjusting mechanical arm grinding clamping device has the high control accuracy with the aid of advanced surgical instruments. The multi-degree-of-freedom skull surgical grinding experiment platform can accurately measure the grinding temperature and the grinding force through constructing multi-degree-of-freedom skull surgical grinding experiment platform.
Conclusion: They can provide guidance for clinical practice and solve the unknown problems in the skull grinding process.
Keywords: 6-degree-of-freedom automatic adjusting device, grinding equipments, grinding force, grinding temperature, multidegree- of-freedom grinding experiment platform, online detection and controllable device, skull grinding.
