Abstract

The paper presents an optical method of damping vibration present in manually operated laser surgical devices. Considering the frequency range of the physiological tremor of 5-15Hz, the design of two compliant positioning mechanisms on 2 axes was made, which will have the role of supporting and moving the focusing lens of the laser device. A couple of compliant structures were subjected to static and dynamic finite element analyzes (modal analysis) to determine the displacement-force characteristic and resonant frequencies, eliminating the risk of operating in the frequency band of physiological tremor. Finally, the structures were teste in laboratory for final experimental results.
