DEVICE FOR GAUGING AND VERIFYING THE PRECISION OF SURGICAL INSTRUMENTS

摘要

A device for accurately positioning and gauging surgical instruments in space has a holder, an element movable in the holder and at least one element for guiding the movable element in the holder. The movable element can be exchanged for another one and is provided with at least one cavity which can be aligned with the holder and holds a surgical instrument that can be inserted into this cavity in an accurately defined position and orientation because it has a shape which corresponds to that of the surgical instrument. The device has means which enable the position and orientation of the device to be determined by an electronic measurement device and stored in an EPROM.
