True micro-motor systems capable of direct and immediate integration are needed in order to advance the technological state and effectiveness of existing minimally invasive surgery (MIS) equipment. In this study, a three degree-of-freedom (DOF) piezoelectric ultrasonic micro-motor is reported, with a major diameter of only 350 μm; the Intellimotor. Upon integrating the micro-motor with a MIS micro-guidewire, a severe loss of actuation performance to the point of inoperability was observed, due to a detrimental loss of acoustic energy from the micro-motor. To combat this, two diameter 300 μm waveguide micro-Bragg reflectors (micro-BRs) were developed. A prototype micro-BR was constructed and tested to verify the ability to reflect otherwise lost acoustic energy, thereby enabling the integration of a resonant micro-actuator, such as the Intellimotor, with standard MIS equipment. © 2012 American Institute of Physics.
