摘要： An ophthalmic surgical device for macerating the lens nucleus in the eye and for removing particles of the macerated lens nucleus from the eye of a living being, includes a hand-held housing with a head piece attached at one axial end of the housing and supporting a guide tube. Disposed in the guide tube is a tubular probe which is operatively connected to a motor drive and projects beyond the guide tube with its tip to carry a cutting element in form of at least two rotatable wing-like blades oriented approximately transversely to the longitudinal axis of the guide tube. By means of the drive, the tubular probe is rotatable relative to the stationary guide tube about the longitudinal axis and movable at a high frequency in direction of the longitudinal axis.

摘要： Apparatus for microsurgical operations on the eye of a living being includes a housing having a compartment which receives a carrier module having a first support structure for conducting a passageway for supply of an irrigation fluid to a surgical site, a second support structure spaced laterally from the first support structure for conducting a second passageway for withdrawal of material from the surgical site, and at least one catch. The compartment which is subdivided in sections by spaced partition walls houses a pump for peristaltically transporting material in the second passageway, an interrupter unit for controlling the fluid flow through the first passageway, and a pull-in and locking mechanism which is engageable with the catch for pulling the carrier module into the compartment in a snap-like manner and releasably securing the carrier module therein such that the interrupter unit is in engagement with the first passageway and the pump is in engagement with the second passageway.

摘要： An aspiration and irrigation system, in particular for performing surgical operations on an eye of a living being to maintain the intraocular pressure, includes a pressure unit for supplying gaseous fluid to the eye via a first fluid passageway and communicating with an infusion unit comprised of successively arranged first and second infusion bottles, both containing a liquid fluid. An irrigation unit is connected with the second infusion bottle for conducting liquid fluid from said second infusion bottle to the eye via a second fluid passageway; with the liquid fluid in the second infusion bottle being pressurized by gaseous fluid supplied from the pressure unit. A multiport valve selectively controls the flow between the first and second fluid passageways to the eye. Tissue and/or gaseous and liquid fluids are removed from the eye by an aspiration unit.
