Abstract
This chapter introduces robotic compliant bending tubular mechanisms that could improve bendable drilling to replace the conventional straight drilling method. A robot-assisted flexible drilling system, where an operator can navigate and control, is playing an increasingly important role in minimally invasive surgeries. In this chapter, we develop prototypes for controllable and bendable drilling at the tip to allow outward incision of the trachea to take place. The flexible drills are to enter the trachea and stiffen adequately to carry out and stabilize the drilling process. Feasibility and design analysis are investigated during system development. The prototypes can achieve bending through actuation, and we envision that such a design will reduce the risk of tracheostomy surgery.
