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.

Apparatus and method for cleaning microsurgical instruments

An injector for inserting an intraocular lens into an eye, comprising a main body () and a plunger (). A guide element () 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 () is in aligned radial bores of the guide element and plunger and extends into a longitudinal slot () of the main body to prevent twisting and to secure the guide element to the plunger. A retaining element () 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.

Modular intraocular lens injector

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.

A cartridge for an intraocular lens (L) for use in an injector (I) has an at least approximately plane resting surface () for supporting the lens (L) in a partially folded or non-folded state, an arched surface () which adjoins the resting surface (), and a sliding element () with which the partially folded or non-folded lens (L) supported on the resting surface () can be slid along the arched surface () 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.

Cartridge for an intraocular lens

A plunger needle () for an intraocular lens injector has a plunger tip () with a contact area for making contact with a lens (L), the contact area being arranged in a front face () of the plunger tip (), which is curved cylindrically. The plunger needle () according to the invention, with its specially configured plunger tip (), 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.

Plunger needle for an intraocular lens injector

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

Injector with finger ring

A device for inserting a lens into an eye has a grip body () with a lens holder () for holding the lens, and a plunger () which can be displaced in the grip body () for guided insertion of the lens into the eye. A ball-bearing bush () is arranged in the grip body (), the plunger () being mounted so as to be laterally displaceable in this ball-bearing bush (). 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.

Device for inserting a lens into an eye

The device comprises a tubular housing having an axis and comprising a suction ring on its lower end face with an annular recess communicating with a corretor for connection to a suction pump. The housing has first stop means and second stop means. A tubular insert is mounted in the housing for rotation around the axis and axially displacable. The insert has a third stop means cooperating with the first stop means for defining an extended position of the insert and a fourth stop means coacting with the second stop means for defining a retracted position of the insert. The insert further has a micrometer female thread. A tubular knife holder with a knife for cutting a circular cut into the cornea is mounted in the insert. The knife holder has a micrometer male thread threaded into the female thread and a head. A scale and a marking on the head and on the insert are provided for preselecting a depth of the cut in the extended position of the insert.

Device for transplanting a cornea on a patient's eye

A roll film cassette facilitating the loading of film in ordinary light conditions without risk of exposure comprises a housing, a window adjacent one end of the housing, a film supply spool for unexposed film and a take-up spool for exposed film at the window end of the housing, and a reversing roller at the opposite end of the housing. The two spools are incorporated into a common spool-holder unit bodily attachable in and removable from the housing. The parts of the spool-holder unit for mounting the supply spool include a light-tight sleeve with an opening for the insertion and removal of the spool. The opening has a hinged door-like lid and an axial slot for the accommodation of a leader portion of the film.

Photographic apparatus for using roll films

The apparatus includes an image field limiting frame and at least one movable mask for the purpose of varying picture size in a line parallel to the direction of film travel and means to control film transport steps proportional to the picture window left open by the mask. It also includes means to directly transport the film in either the forward or reverse direction during picture size adjustment so that the forward edge of the film matches the forward edge of the picture window. In this manner, it is possible to execute picture size changes at anytime, even after operation of the film transport, without waste of film or overlap of sequential pictures.
