Medical Applications

With their tiny size and high precision, M3 micro-mechatronic modules are ideal for use in medical devices, robotic surgical tools and precision analytical instrumentation. We can create non-magnetic motion systems for safe operation in MRI environments.

Medical applications include:

• Instruments. Tiny smart motion systems move optics in scientific instruments for flow cytometry, DNA identification, pathogen detection, DNA sequencing and more. They enable smaller, field-portable systems and faster, lower-cost tests.
• Endoscopic surgery. Steer a beam in an endoscopic laser scalpel, focus a lens in an in vivo camera, manipulate a scraper, collect a sample or dispense a liquid. Small enough to fit inside the endoscope head, our mechatronics systems improve accuracy and eliminate the need for a cable control system.
• Electrophysiology. Motorized microdrive arrays enable precision electrode positioning.
• Medical imaging. Modules for lens control and laser tuning in diagnostic imaging systems. Their small size and precision enable point of care diagnostics, real-time automated data collection and augmented vision systems.
• Implantable devices. Adjust implanted devices in situ for drug delivery, orthopedics (bone growth and spine straightening), audiology, neurology, pain management, sleep apnea treatment and more. The implanted devices can be non-magnetic and MRI-safe.
• Robotic surgical devices. Everything from robotic grippers and retractors to miniature mobile robots for minimally invasive surgery.

Benefits

M3 micro mechatronic modules are:

• Small – for implantable and portable devices
• Precise – for extremely accurate positioning or dosing
• Quiet – for unobtrusive wearable medical devices
• Robust – for high reliability
• Efficient – battery-operated with lower power consumption than traditional micro-motors

SQUIGGLE motors generate no electromagnetic fields and can be made entirely from non-ferrous materials for use in or near MRI systems without affecting image quality or motor performance.

Solutions

M3 micro-mechatronics modules are complete closed-loop actuators with high precision and tiny footprints. Each module incorporates a SQUIGGLE micro motor, position sensor, and all drive electronics. You supply simple motion commands using a standard serial interface. Modules have low power consumption and 3.3V input voltage for battery-powered operation. M3 modules are quickly customized to your medical application. For details see our M3 module design platform.

SQL Series SQUIGGLE motors are tiny, battery-driven motors (less than 3 x 3 x 6 mm) for wearable and implantable medical devices, endoscopes, tiny cameras and more. For details and specifications see our miniature OEM motors.

Custom solutions based on our expertise in piezoelectric motion systems give you what you need: higher force, higher precision, operation in vacuum or  cryogenic environments, non-ferrous versions for use in high-magnetic (MRI) environments. For examples please see our custom motion systems.
