Abstract: A phacoemsulsification needle for use with an ultrasonic handpiece in performing cataract surgery has a plurality of external grooves along its shaft. The external grooves are configured to convert longitudinal drive motion delivered by the handpiece at the base of the needle into torsional motion at the needle tip. The torsional motion at the needle tip has a magnitude greater than the magnitude of the longitudinal drive motion at the base, i.e. the longitudinal to torsional gain is greater than one. The grooves may be helical grooves, wherein the groove configuration is defined by a set of groove parameters including a helical pitch of the grooves, a width of the grooves, a depth of the grooves, an axial length of the grooves, and a total number of grooves.
Abstract translation: 在执行白内障手术时与超声波手持件一起使用的晶状体乳化脉冲针具有沿其轴的多个外部凹槽。 外部凹槽构造成将由手针底座处的手持件传递的纵向驱动运动转换成针尖处的扭转运动。 针尖处的扭转运动的幅度大于在底部的纵向驱动运动的大小，即纵向扭转增益大于1。 凹槽可以是螺旋槽，其中凹槽构型由一组凹槽参数限定，包括凹槽的螺距，凹槽的宽度，凹槽的深度，凹槽的轴向长度和总数 的凹槽。

Abstract: A multi-lumen sensing system (10) includes medical tubing (20) having a plurality of lumens (22A, 22B) and at least one secondary passageway (24) extending in an axial direction of the medical tubing, wherein the secondary passageway is between the plurality of lumens. The multi-lumen sensing system may include a sensing receptacle (30) defining a channel (32) in which a lengthwise portion of the medical tubing is received. A plurality of ultrasonic transmitting elements (40T, 42T) may be arranged within the secondary passageway of the medical tubing or as part of the sensing receptacle for transmitting respective ultrasonic signals across the lumens to a corresponding plurality of ultrasonic receiving elements (40R, 42R) of the sensing receptacle. Alternatively, the sensing receptacle may include a plurality of ultrasonic transmitting and receiving elements (40, 42, 44) transmitting respective signals across the lumens for return reflection at an interface of the secondary passageway.
