US 7,166,117 B2 · Automatic surgical device and control assembly for cutting a cornea

Abstract

A surgical device for cutting substantially across a cornea of an eye of a patient, the device including a positioning ring to be attached to an eye surrounding a cornea to be cut, and defining an aperture sized to receive and expose the cornea to be cut. The surgical device further includes a cutting head assembly structured to be guided and driven over an upper surface of the positioning ring in a generally arcuate path, and having a cutting element positioned therein and structured to oscillate laterally to facilitate smooth and effective cutting of the cornea. The cutting head assembly is structured to be detachably coupled to the positioning ring by a coupling member which permits movement of the cutting head assembly relative to the positioning ring along the generally arcuate path, but maintains sufficient engagement therebetween to ensure that smooth, steady, driven movement is maintained.

A microkeratome cutting blade assembly for use with a surgical device that cuts at least partially across the cornea of an eye of a patient along an arcuate path, comprising:

a blade having a blade holder attached thereto;
said blade having a front portion and rear portion;
said front blade portion having a cutting edge for cutting a portion of the cornea of an eye;
said front portion having an overall dimension which is larger than the rear portion;
said blade having an edge for engaging said blade holder;
said blade holder having a top side and an underside said underside having a flanged portion which engages said edge whereby moving said blade holder correspondingly moves said blade;
