Some press for our research work on micromotors for neurosurgery (NeuroGlide®) (video courtesy Channel 7, all rights reserved Channel 7). Channels 9, 10, ABC, SBS, NZ Herald, Sydney Herald and a few others picked up on this. Nice to see the years of effort from our invention come to a little press after all the difficulties we’ve had.
Multi-degree-of-freedom ultrasonic micromotor for guidewire and catheter navigation: The NeuroGlide actuator
A 240-µm diameter ultrasonic micromotor is presented as a potential solution for an especially difﬁcult task in minimally invasive neurosurgery, navigating a guidewire to an injury in the neurovasculature as the ﬁrst step of surgery. The peak no-load angular velocity and maximum torque were 600 rad/s and 1.6 nN-m, respectively, and we obtained rotation about all three axes. By using a burst drive scheme, open-loop position and speed control were achieved. The construction method and control scheme proposed in this study remove most of the current limitations in minimally invasive, catheter-based actuation, enabling minimally invasive vascular surgery concepts to be pursued for a broad variety of applications.
