Abstract: The invention relates to an instrument for stimulating or irritating and/or abrasively treating and/or polishing a membrane or surface or inner surface in the human or animal eye, comprising a handle (1), which comprises an actuating element (2), and a probe (3), which adjoins the handle (1) and which is open at the free distal end, for introducing into the eye. The invention is characterized in that the probe (3) comprises a loop (4) in the interior, and the loop can be at least slightly pushed out of the probe (3) and pushed or pulled back into the probe (3) by means of the actuating element (2).

Abstract: The present invention relates to a device for cutting and aspirating tissue from the human or animal body, in particular for use in vitrectomy, epiretinal membrane peeling, etc., with an outer tube (1), and with an inner tube (2) which is movable to and fro and concentrically in the outer tube (1) with slight play, wherein the outer tube (1) is closed at the free end and has, near the free end, at least one lateral opening (3) with at least one inner cutting edge (5), wherein the inner tube (2) is open at the free end and there has an outer cutting edge (4), and wherein the cutting edges cooperate in a cutting action during the movement of the inner tube (2) relative to the outer tube (1), advantageously characterized by a shaping measure in or on the outer tube (1) and/or in or on the inner tube (2), whereby the inner tube (2), at least in the area of the lateral opening (3), runs in the outer tube (1) with at least slight pretensioning.

Abstract: A hollow needle for an instrument used in ocular surgery for the in-vivo disintegration of organic lenses via ultrasound, having a functional part (1) and a connector part (2), with the connector part (2) having handling portions(3) and serving to attach the tool in a removable fashion to a handle, wherein the properties of the handling portions (3) change upon connection of the tool to the handle, removal of the tool from the handle, and/or upon reprocessing of the tool. In addition, a method is disclosed for the production of a corresponding medical tool.
