    • A table includes a support leg having an elongated channel extending longitudinally along at least a portion of the support leg and opening laterally outwardly from said support leg. The channel has an open end at a top of the support leg. In a preferred embodiment, a catch member extends across at least a portion of said channel and a worksurface is supported by the top of said support leg. In another aspect, the worksurface has a cutout shaped to receive at least a portion of the top of the support leg with at least a portion of the channel nested in the cutout. In a preferred embodiment, the support leg includes a socket that is shaped to receive a portion of the worksurface. A method of routing a utility line on a table is also provided.
    • 桌子包括支撑腿,该支腿具有沿着支撑腿的至少​​一部分纵向延伸并从所述支撑腿侧向向外开口的细长通道。 通道在支撑腿的顶部具有开口端。 在优选实施例中,捕捉构件延伸穿过所述通道的至少一部分,并且工作表面由所述支撑腿的顶部支撑。 在另一方面,工作面具有切口,该切口成形为接收支撑腿的顶部的至少一部分,其中通道的至少一部分嵌套在切口中。 在优选实施例中,支撑腿包括成形为容纳工作面的一部分的插座。 还提供了在表上路由实用程序线的方法。

    • An irrigation-suction handpiece assembly, for dental and surgical use at an operating site, includes a handle containing longitudinally extending, side-by-side suction and irrigant passageways respectively connectible to a source of subatmospheric pressure (i.e., a vacuum source) and an irrigant fluid source. An irrigant valve is actuable for alternately opening and blocking flow of irrigant from the irrigant source through the irrigant passageway. An air pressure conduit includes a third passageway in the handle and connectible to an air pressure source which is not atmospheric pressure and not influenced by pressure changes in the suction passageway. This air pressure source is either a further subatmospheric pressure source or a compressed gas source. The third passageway has a relief opening in the handle selectively openable or closable by the hand of the operator for effecting a change in the pressure within the third passageway. The irrigant valve has a control input coupled with the air pressure conduit and third passageway and responsive to such change in air pressure therein for shifting between its open and blocking states to thereby control the flow of irrigant fluid to the operating site.
    • 用于在操作现场进行牙科和外科手术使用的冲洗抽吸手柄组件包括手柄,其包括分别可连接到低于大气压力的源(即,真空源)的纵向延伸的并排抽吸和冲洗通道,以及 冲洗液源。 冲洗阀是可启动的,用于交替地打开和阻止冲洗液从冲洗源通过冲洗通道的流动。 空气压力导管包括在手柄中的第三通道,并且可连接到不是大气压并且不受吸入通道中的压力变化影响的空气压力源。 该空气压力源是另一个低于大气压的压力源或压缩气体源。 第三通道在手柄中具有可选择地由操作者的手可打开或关闭的释放开口,用于实现第三通道内的压力变化。 冲洗阀具有与空气压力管道和第三通道耦合的控制输入,并响应于其中的空气压力的这种变化,以在其打开和阻塞状态之间移动,从而控制冲洗流体到操作现场的流动。
