Title: Accuracy Enhancement for Microsurgery

The next level of microsurgical practice will require finer position control
than unassisted surgeons can attain.  Approaches such as telerobotics have
been developed, but these are expensive and rather obtrusive for the
surgeon.  The solution which my students and I propose is a hand-held
instrument with active compensation of positioning error.  This scenario
offers considerable promise but raises several challenging issues, including
adequate sensing and actuation within a sufficiently small package, and
real-time discrimination between desired and undesired movement.  I will
summarize recent progress toward this goal, and briefly describe what
remains to be done.
