| description | The invention relates to 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 ultrasonic waves, wherein a suction channel (6) for suctioning lens fragments extends in the axial direction through the hollow needle, the opening of which is delimited by the effective surface (5), characterised 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 thewall (10) of the suction channel.
本发明涉及种用于眼科手术器械的空心针，所述眼科手术器械通过超声波在体内破碎有机晶状体，所述空心针包括形成在近端(1)上与所述器械连接的连接区(2)；以及形成在远端(3)上且具有用于发送超声波的有效表面(5)的针头(4)，其中用于抽吸晶状体碎片的抽吸通道(6)在轴向方向上延伸穿过所述空心针，所述抽吸通道的开口由所述有效表面(5)限定，其特征在于，位于所述针头(4)内的所述抽吸通道 |
