An ability of creation and usage of small movement automated devices for minimally invasive ophthalmologic surgeries
The possibility of creating small, automated devices for the movement parts of medical equipment in usage, based on piezoelectric actuators, have been examined in this article. Movements are performed according to the trajectories set by the established treatment method. A variety of minimally invasive surgery, for example: detachment of retina or internal tumors in human eye, are made by hand influenced by subjective human factor. A large group of existing piezo actuators with translational motion have been analyzed and the best option for specific problems have been chosen. The microcontroller based engine control circuit has been designed. The items for its production were selected, as well taking into account such factors as accuracy, dimensions, efficiency and convenience of installation at the equipment. Conclusions about the prospects of working towards creating algorithms for motion adapter (for treatment of the individual patient, with pre-made medical MRI, CT or ultrasound examinations) and creating feedback system (to adjust the movement of the laser adapter, which exclude the impact of involuntary pupil movements of the patient's eye) have been made.
