Abstract
A one-hand device for an ocular irrigation and aspiration has a tube (3), which having a tip (5) at a front end, wherein the tip (5) has an irrigation fluid orifice outlet (5a) for the exit of the irrigation fluid and an aspiration opening (5b) for taking up the material to be extracted by suction. An irrigation fluid pump (11) is arranged in the tube (3) and is connected to the irrigation fluid orifice outlet (5a) via an irrigation conduit (115). In the tube (3) an aspiration pump (12) is arranged, which is connected to the aspiration opening (5b) via an aspiration conduit (125). A controller (13) regulates the flow rate through the irrigation conduit (115) such that it is equal to the flow rate through the aspiration conduit (125). Preferably a cutting tool/milling tool is rotatably mounted in the aspiration opening (5b).

4. A device for removing body tissue in a surgical intervention having:
-
a tube having a longitudinal axis, the tube further having an aspiration conduit and an aspiration opening for taking up the removed tissue, a cutting body/milling body that is mounted inside of the tube for rotating around an axis of rotation, wherein the cutting body/milling body at least at a part of its periphery has a plurality of separation edges, wherein the cutting body/milling body is mounted such that the separating edges are successively exposed in the aspiration opening towards the outside of the tube and in doing so are nearly tangential to the aspiration opening when the cutting body/milling body rotates around the axis of rotation and wherein the aspiration conduit is run to the aspiration opening outside of the cutting body/milling body characterized in that said axis of rotation is tilted with respect to said longitudinal axis of the tube or perpendicular to it. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 15, 25, 26, 27, 28, 29, 30, 31, 32, 33)
