Abstract
A cutting device for ophthalmologic surgery in the eye of a living being specifically for suctioning, cutting and removing portions of the vitreous humor of the eye and/or tissue particles, includes a housing and a probe disposed thereon for insertion into the vitreous humor with the probe including a guide tube with a suction opening at its distal end and an inner tube co-axially inserted therein which is slideably movable in axial direction relative to the suction opening, and a control member configured to translate a rotational movement of the drive into a linear movement of the inner tube to thereby move the inner tube in the guide tube in the direction of the longitudinal axis from the resting position to the closing position and back to the resting position while preventing a linear movement of the inner tube at rotating drive when the inner tube is in the resting position.
