Abstract:

An accurate three-dimensional optical sensing system to track the tip of a microsurgical instrument has been developed for laboratory use. The system is useful for evaluation of mirosurgical instrument designs and devices for accuracy enhancement both robotic devices and active hand-held instrument, as well as for assessment and training of micro- surgeons. It can also be used as a high-precision input interface to micro-surgical simulators. Tracking is done by illuminating the workspace at an infrared wavelength and using optical sensors to find the position of a small reflective ball at the instrument tip.
