Abstract

Physiological hand tremor severely affect the accuracy of the manipulation of ophthalmology robot. Ophthalmologic operation is performed under microscope, where circular continuous curvilinear capsulorhexis during cataract surgery is a typical operation in ophthalmologic surgical requires high accuracy, so tremor suppression is in demand. We introduced three methods: The Weighted Frequency Fourier Linear Combiner(WFLC), Kalman Filter(KF) and Moving Average Filter(MAF) to clarify the effect on physiological tremor suppression. Haptic device was used as master manipulator to gather data, by draw a circle to roughly simulate the circular continuous curvilinear capsulorhexis during cataract surgery. Previous studies have shown that the frequency of physiological hand tremor range of 8 to 12 Hz. Extend it to 6-14Hz for reliability. The results have be shown that: In 10 trails, The Weighted Frequency Fourier Linear Combiner reduced the RMS amplitude of motion by 74% within 6-14Hz in the task we defined, which best fit the requirement among three methods.
