Abstract: A surgical cartridge includes an inner plate; and an outer plate arranged approximately parallel to the inner plate. The flow paths between the inner plate and the outer plate are arranged to form an irrigation flow path for directing fluid towards the surgical site via an irrigation connection and an aspiration flow path for directing fluid away from the surgical site via an aspiration connection. The inner plate includes membranes adapted for cooperation with plungers and/or valves of a membrane pump. The membranes include a main membrane, at least two valve membranes and an auxiliary membrane adapted to cooperate with a main membrane plunger, valve and an auxiliary membrane plunger of the pump, respectively.

Abstract: The invention relates to an eye surgical lighting unit for lighting internal ocular tissue. The lighting unit comprises a fiber having a proximal end and a distal end, for guiding a light beam to the distal end. The lighting unit also comprises a manual unit, provided with a cannula and a handle having an internal passage positioned in line with the cannula. The fiber is adjustable between an intraocular operational position in which the fiber extends through the internal passage of the handle and through the cannula, and a chandelier operational position in which the fiber is uncoupled from the manual unit.

Abstract: An irrigation/aspiration system for irrigating and aspirating a surgical site includes an irrigation flow path for directing fluid towards the surgical site via an irrigation connection, and an aspiration flow path for directing fluid away from the surgical site via an aspiration connection. A membrane pump is arranged for pumping fluid through the irrigation flow path and/or the aspiration flow path. The membrane pump includes a main pump chamber, at least two valves for opening and/or closing the main pump chamber and an auxiliary pump chamber arranged between the irrigation connection and/or aspiration connection and the main pump chamber for compensating movement of a main pump plunger element in the main pump chamber to provide for an approximately even fluid flow to and/or from the surgical site.

Abstract: An eye surgical instrument, comprising at least one optical fiber for lighting of the interior of the eye, which at least one optical fiber, at a free end thereof, is provided with a light exit and with a stop situated at a distance from the free end, which stop defines an insertion part situated between the end and the stop, and at another end is connectible to a light source, while the stop forms a separate element which is arranged so as to be slidable along the at least one fiber.

Abstract: The invention relates to an ophthalmic system for controlling an infusion liquid pressure at a distal end of an ophthalmic irrigation device penetrating an eye and being connected to an irrigation line for feeding the device with an infusion liquid. The system comprises a processor that is arranged for estimating a compensation pressure for compensating an internal pressure loss in the eye due to surgical acts in the eye. The estimation result is used for dynamically adjusting, in response to the estimated compensation pressure, the pressure of the irrigation liquid in the irrigation line. The estimation step is based on a configuration and/or actual operation of an ophthalmic surgical device performing the surgical acts in the eye.

Abstract: The invention relates to an ophthalmic surgical device for the treatment of glaucoma. The device comprises a fiber connector and a fiber. The fiber is provided with a proximal end connected to the fiber connector. Further, the fiber is provided, near its distal end, with a notch. Preferably, the distal end of the fiber forms a rounded tip.

Abstract: The invention relates to an ophthalmic device for intravitreal administration of a substance into a human or animal eye by means of a needle. The device comprises a support structure having a lower surface for contacting the conjunctiva of the sclera, the lower surface being provided with an aperture for receiving the needle. The support structure further comprises a substantially tapering part directed away from the lower surface. In addition, the device comprises a channel provided in the tapering part wherein a first end of the channel forms the aperture in the lower surface.

Abstract: A surgical hand tool, comprising a handle with a substantially elongated fluid guide extending away therefrom, which fluid guide terminates, at a distal end, in a brush head and is connectable, at a proximal end, to the fluid chamber accommodated in the handle, such that, during use, fluid can flow from the fluid chamber through the fluid guide in order to be dispensed via the brush head, wherein the brush head is accommodated in an insertion sleeve, and is slidable from a first position in which the brush head is located inside the insertion sleeve to a second position in which at least a part of the brush head extends outside the insertion sleeve.

Abstract: An eye surgical unit, comprising a connecting module to align, upon coupling of the connecting module to a connecting module of an eye surgical instrument, an end of a light guide which is included in the connecting module of the eye surgical instrument with respect to the connecting module of the eye surgical unit. During coupling, the connecting modules of the eye surgical unit and the eye surgical instrument mutually cooperate. The mutual cooperation of the connecting modules is realized through a multiple-thread screw connection of which corresponding screw connection elements, upon coupling of the connecting modules through mutual rotation of the connecting modules, mutually engage substantially simultaneously.
