Abstract: A cleaning apparatus for microsurgical instruments has a flush chamber closed off at one end by a first plug adapted to liquid-tightly grip one end of the instrument, allowing a portion of the instrument to extend past the first plug and out of the flush chamber. The other end of the flush chamber is closed off by a second plug having an inlet port. Liquid injected through the inlet port on the second plug passes through an internal passageway formed in the instrument and exits the instrument through the portion that extends past the first plug. In another embodiment the instrument has an internal passageway and an end cap through which flushing ports are formed which communicate with the passageway. A first plug having an inlet port is liquid-tightly attached to the end cap and liquid injected into the first plug passes through the plug, through the flushing ports and through the passageway to clean detritus from the instrument.

Abstract: An injector for inserting an intraocular lens into an eye, comprising a main body (10) and a plunger (50). A guide element (30) is connected to the distal end of the plunger to laterally guide the plunger during movement along a longitudinal axis (L). The distal end of the guide element has a structure for fastening a plunger needle to the guide element. A radial guide pin (40) is in aligned radial bores of the guide element and plunger and extends into a longitudinal slot (17) of the main body to prevent twisting and to secure the guide element to the plunger. A retaining element (24) interacts with a running surface on the perimeter of the plunger, the running surface having a variable radial distance from the longitudinal axis so as to cause an axial resistance force which depends on the axial position of the plunger.

Abstract: A cleaning apparatus for microsurgical instruments of the type having screw-type mechanisms used to advance or retract a plunger has a hollow sleeve into which the injector is liquid-tightly inserted, the sleeve being configured to hold the plunger in a fixed position when the plunger is disengaged from the injector body. A cap having an inlet port is liquid-tightly attached to the sleeve and cleaning liquid is forced from a syringe into and through the inlet port, flushing detritus from the injector. Various sizes and shapes of sleeves are used to accommodate different injectors.

Abstract: A surgical instrument for both chopping and splitting the nucleus of an eye has a handle housing a shaft mounted within a guide tube which slides into and out of the instrument to bring first and second jaws into and out of contact with one another. The jaws are planar and positioned approximately perpendicular with the axis of the handle. The bottom edges of the jaws are brought into alignment to form a cutting edge when the jaws are forced together, and separate to perform a splitting action within a cut when the jaws are moved apart.

Abstract: A surgical instrument which both incises and splits the nucleus of a lens has a pair of 5 spring steel segments slidably received in a metallic tube. Each segment terminates in a tip. As the spring steel segments are drawn into the tube the tips come together to form a cutting edge useful for incising the lens. When the segments are extended from the tube the tips separate, forcing the incision open until the lens is split.

Abstract: A cartridge for an intraocular lens (L) for use in an injector (I) has an at least approximately plane resting surface (4) for supporting the lens (L) in a partially folded or non-folded state, an arched surface (11) which adjoins the resting surface (4), and a sliding element (3) with which the partially folded or non-folded lens (L) supported on the resting surface (4) can be slid along the arched surface (11) and folded, in particular rolled. By means of this cartridge, an intraocular artificial lens can be brought to the smallest possible format in a simple manner and without damage to the lens.

Abstract: A plunger needle (3) for an intraocular lens injector has a plunger tip (4) with a contact area for making contact with a lens (L), the contact area being arranged in a front face (40) of the plunger tip (4), which is curved cylindrically. The plunger needle (3) according to the invention, with its specially configured plunger tip (3), permits reliable guiding of the lens (L) upon injection into an eye and prevents the lens (L) becoming stuck in the injector. It is also easy to produce.

Abstract: A hand-operated injector for inserting a lens into an eye has a grip body (1) with a lens holder (13) for holding a lens, and a plunger (2) arranged displaceably in the grip body (1) for guided insertion of the lens into the eye. An actuating means (5, 6) for displacing the plunger (2) relative to the grip body (1) is arranged on the plunger (2), which actuating means (5, 6) is rotatable relative to the plunger (2). The injector can thus be rotated through any desired angle, without having to substantially change the position of the hand pressing on the plunger (2), in particular the position of the thumb.

Abstract: A device for inserting a lens into an eye has a grip body (1) with a lens holder (13) for holding the lens, and a plunger (2) which can be displaced in the grip body (1) for guided insertion of the lens into the eye. A ball-bearing bush (3) is arranged in the grip body (1), the plunger (2) being mounted so as to be laterally displaceable in this ball-bearing bush (3). This allows the device to be operated using one hand, said device additionally having good slide properties and permitting an at all times guided lateral or rotational movement of the plunger.
