摘要： A transducer activated tool for contacting workpiece surfaces and directing fluid adjacent to said surfaces is disclosed. The tool may be ultrasonically activated by attachment to an insert (11) that includes a magnetostrictive element (14). The tip (20, 50, 60, 80, 90) includes distal surfaces (58, 63, 81, 95) shaped to contact the workpiece and additionally includes a fluid passageway (45, 53, 61, 91) internal to the tip (20, 50, 60, 80, 90) that is bored generally along the centerline of the tip (20, 50, 60, 80, 90) but is offset (54, 93) from the tip axis (56, 92) such that a discharge orifice (46, 52, 57) is formed in the tip (20, 20, 50, 60, 80, 90) displaced from the distal tip end (58, 63, 81, 95). The passageway (45, 53, 61, 91) is preferably angularly offset (54, 93) so that the discharge orifice (46. 62, 57) is formed in the distal end (58, 63, 81, 95) of the tip (20, 50, 60, 80, 90) about 2-8 mm from the distal end (58, 63, 81, 95) of the tip. The tip (20, 50, 60, 80, 90) when shaped to conform to dental or tooth surfaces is particularly useful as a dental tool. In another embodiment the fluid passageway (91) is eccentrically offset (93) from the tip axis (92) wherein the passageway (91) is substantially parallel to the center axis (92) but displaced therefrom preferably by about 0.1 to 0.5 mm. The tip end and fluid delivery passageway discharge orifice (46, 62, 57) are located relative to each other such that fluid is provided to the workpiece or tip without the formation of excessive spray and without weakening the distal tip such that it is sufficiently strong to provide useful service in resisting flexural stresses and the like.
摘要翻译：公开了一种用于接触工件表面并引导邻近所述表面的流体的换能器启动工具。该工具可以通过附接到包括磁致伸缩元件（14）的插入件（11）来超声激活。尖端（20,50,60,80,90）包括成形为接触工件的远端表面（58,63,81,95），并且另外包括在尖端内部的流体通路（45,53,61,91）（20,50,60,80,90），其通常沿尖端（20,50,60,80,90）的中心线钻出但与尖端轴线（56,92）偏离（54,93），使得在从远端尖端（58,63,81,95）移位的尖端（20,20,50,60,80,90）中形成排出孔口（46,52,57）。通道（45,53,61,91）优选地成角度地偏移（54,93），使得排出孔（46,62,57）形成在尖端的远端（58,63,81,95）中（20,50,60,80,90）距末端的远端（58,63,81,95）约2-8mm。当成形为符合牙齿或牙齿表面时，尖端（20,50,60,80,90）作为牙科工具特别有用。在另一个实施例中，流体通道（91）偏离顶端轴线（92）偏移（93），其中通道（91）基本上平行于中心轴线（92），但优选偏离约0.1至0.5mm。尖端和流体输送通道排放孔（46,62,57）相对于彼此定位，使得流体被提供给工件或尖端而不形成过度喷射并且不削弱远侧尖端使得足够强为抵抗弯曲应力等提供有用的服务。
