The Influence of Drill Sterilization and Drill Guide Modifications on the Quality of Bone Drilling Process

This paper investigates influence of dry sterilization process on the dynamics of the medical drill wear rate, as well as the effects of slotted drill guide on bone drilling temperature. Experiments were characterized with the machining parameters commonly used in everyday surgical practice. Both experiments were performed using standard commercial surgical drills. Dry sterilization is selected due to the higher temperatures and cycle durations compared to the steam sterilization, in order to expose the drill to greater thermal stress. Surgical drill guides were perforated with two symmetrical helical slots near the drilling zone in order to ensure faster bone chip removal and to prevent chip obstruction inside the guide channel.
