Cornea surgery device for eye surgery has drive unit having two independent motors surmounting cutter head such that motors have parallel shafts perpendicular to trajectory plane of cutter head

摘要

A cutter head (200) moves along a plane trajectory parallel to a base (100) to be fixed to the eye of a patient. A guide leads the cutter head. A drive unit (300) drives a cutter head blade to reciprocate parallel to a cutting edge. The drive unit has two independent motors (302,303) surmounting the cutter head with the parallel shafts (304,305) perpendicular to the trajectory plane of the cutter head.
