Current surgery robots can be very large for an operating room and very expensive for hospital budgets. Designing small surgery robots conceived for specific purposes would solve the problems of cost and size.
The advantages of such a robot are:
-- It is inexpensive.
-- It does not take as much space as conventional medical robots in the operating room.
-- It is safe, as its power and motion range are restricted.
-- It is mounted directly on the patient bone, and thus does not require tracking.
On the image, the miniature robot (10) has a parallel structure with six degrees of freedom. It is fitted with a mechanical guide for needle, probe or catheter insertion (20).
