Medical Applications

The medical industry has long depended on cutting edge technology to provide patients with the best care possible. From Imaging to scanning and robotic surgical devices; the applications for piezoelectric motor technology is broad and the technology is key in providing the best care possible.

Robotic Surgery

To minimize tissue trauma robotic surgery requires very precise movements coupled with great stability. Piezoelectric motors are uniquely suited for such applications. Firstly, they have nanometer level resolution, secondly the self-holding torque (or force) is extremely high often eliminating the need for any break/holding mechanism. At the end effector of the robot compactness is normally critical, DTI’s miniature rotary piezomotor (Model PM-1124R-HS) and linear piezomotor (Model LPM-2C) provide a range of useful applications.


Surgical Tools

Motorized surgical tools including drills, microsaws, dissecting tools and injectors can all benefit from the light weight and compact size of the piezomotor, therefore reducing surgeon fatigue and risk to patient.

Scanning

Various instruments used in medical scanning (e.g. MRI) are motorized. In order to overcome the strong electromagnetic fields, such motorized devices require heavy lead shielding to protect the motor and or prevent image distortion. Because piezomotors are not effected by EM fields they are uniquely useful for such applications.

Laboratory Automation

The most widely known application of laboratory automation technology is laboratory robotics which comprises many different automated laboratory instruments, devices (the most common being autosamplers) and methodologies used to enable, expedite and increase the efficiency and effectiveness of scientific research in laboratories. Such instruments and devices require fast, accurate movements and are well suited for piezomotor control.
