Abstract:
A hollow needle for an ophthalmic surgical instrument for in-vivo fragmentation of organic lenses by means of ultrasound, comprising a connection region (2) formed on the proximal end (1) for coupling onto the instrument and a needle head (4) formed on the distal end (3) having an effective surface (5) for emitting ultrasound waves, wherein a suction channel (6) for suctioning lens fragments extends in the axial direction through the hollow needle, the opening (7) of which is delimited by the effective surface (5), characterized in that the suction channel in the needle head (4) is formed in a conical manner at least partially running in the direction of the proximal end (1), and in that sections (9) running over this region (1) in the axial direction are formed in the wall (10) of the suction channel.
