Analysis of Compact Bone Vibration Assisted Drilling

Abstract:

Bone drilling is often used in trauma care, orthopedic and other type of surgical procedures. The elevated temperatures caused by friction may lead to temperature induced bone necrosis. This paper presents an analysis of the effect vibration assisted drilling has on the drilling temperature of the compact bone.The experimental setup was developed and two-type experiments have been conducted. The main aim was to analyze the low frequency vibrations assisted drilling effect on the drilling temperature of poly-methyl methacrylate (PMMA) and bone samples. The temperatures at the exit hole were measured using the thermal camera. The rotational speed of the drill, applied force, parameters of the drill and the samples were considered as constant, whereas the amplitude and frequency of vibrations were varied during the experiments. The obtained experimental data showed the decrease in the drilling temperatures of the vibrated bone samples, as compared to the conventional drilling. It should be noted that further investigation and research related to the vibration assisted drilling should be carried out using different type of bone samples and experimental conditions.
