Abstract: A cutting blade assembly for microkeratome includes a blade (8) with a rectilinear cutting edge (9), the blade being integral with a support (10) with substantially constant profile (11) along one longitudinal dimension parallel to the cutting edge (9) and delimited by an outer surface (12) having a notch (14) substantially orthogonal to the cutting edge (9) of the blade (8), wherein the outer surface (12) has a clearance (15, 17) parallel to the cutting edge of the blade extending from one end (10a) of the support up to a specific distance of the notch (14).

Abstract: A device for surgery of the cornea comprising: an annular base (100) for fixing the apparatus to the eye of a patient; a cutter head (200) comprising a body (200a) and a blade (201) suitable for being displaced along a plane trajectory parallel to the annular base (100); guide means (106) for guiding the cutter head (200) relative to the base (100); drive means (302) for driving the blade (201) in the cutter head (200) with reciprocating linear motion parallel to its cutting edge (201b); and drive means (303) for driving the cutter head (200) relative to the annular base (100) along said trajectory. Said drive means (302, 303) comprise two independent motor units surmounting the cutter head and having mutually parallel outlet shafts (306, 310) perpendicular to the plane of the trajectory of the cutter head (200).

Abstract: A cutter blade assembly for a microkeratome, the assembly comprising a blade (8) having a rectilinear cutting edge (9) and being secured to a support (10) of profile (11) that is substantially constant along a longitudinal dimension parallel to the cutting edge (9) and that is defined by an outside surface (12) including a notch (14) substantially orthogonal to the cutting edge (9) of the blade (8), wherein said outside surface (12) possesses a setback (15, 17) parallel to the cutting edge, extending from one end (10a) of the support to a determined distance from the notch (14).

Abstract: A device for surgery of the cornea includes an annular base for fixing the device to the eye of a patient and a cutter head including a body and a blade assemble. The blade assembly includes a blade and a blade carrier with a resilient tongue integral with the blade carrier. The resilient tongue has a stud located at one end. The cutter head is a one piece body with provisions to connect it to a drive. An orifice is formed in the body for accepting the blade assembly.

Abstract: A microkeratome cutter head comprising a body and a cutter blade slidably mounted in a housing passing through the body in a direction substantially parallel to the cutting edge of the blade, wherein the blade possesses a slot parallel to its cutting edge and opening out into one of the side edges of the blade, while the housing possesses a partition received in the slot of the blade as it is inserted into the body, and co-operating with the edges of the slot to guide the blade in its motion parallel to its cutting edge.

Abstract: A cutter head for a microkeratome, the head including a guide housing for an alternating cutter blade having a cutting edge, a rear edge, and two side edges, the housing having two parallel pairs of faces that are spaced apart by a distance substantially equal to the thickness of the blade and that are situated respectively in the vicinity of the cutting edge and the vicinity of the rear edge of the blade, wherein 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.

Abstract: A device for surgery of the cornea includes an annular base for fixing the apparatus to the eye of a patient. A cutter head includes a body and a blade. The cutter head is displaced along a plane trajectory, parallel to the base. A guide is provided on the base and guides the cutter head relative to the base. A first drive imparts movement to the blade in the cutter head with a reciprocating linear motion parallel to the blade's cutting edge. A second drive imparts movement to the cutter head relative to the base along the trajectory. The first and second drives include independent motor units surmounting the cutter head and having mutually parallel outlet shafts perpendicular to the plane of the trajectory of the cutter head.
