CUTTER HEAD FOR MICROKERATOMES FITTED WITH DISPOSITIONS APPLICABLE TO ALL TYPES OF MICROKERATOME

摘要

PURPOSE: A cutter head for microkeratome is provided to avoid producing particles, even when inserting a blade. CONSTITUTION: The cutter head(1) for a microkeratome includes a guide housing(5) for an alternating cutter blade having a cutting edge, a rear edge, and two side edges. The housing has two parallel pairs of faces(7a,7b,8a,8b) that are spaced apart by a distance substantially equal to the thickness of the blade. The two parallel pairs of faces are situated respectively in the vicinity of the cutting edge and the vicinity of the rear edge of the blade. Each of the pairs of parallel faces is of a length measured parallel to the cutting edge that is shorter than the distance between the lateral edges of the blades in register therewith, minus the peak-to-peak amplitude of the reciprocating oscillation.
