摘要： An improved ultrasonic surgical handpiece (10) includes an angled connecting body (72) between the transducer (70) and operative tip (74), with the connecting body being bent at a location between the node and antinode at its respective ends and with a second nodal plane support in the transducer section. The vibrating assembly (14) is impedance matched to the frequency of a handpiece employing a straight connecting body of substantially equal length and dimension whereby straight and angulated handpieces may be interchangeably used in an ultrasonic surgical system employing a common drive and common operative tips. In a preferred embodiment, the ultrasonic tranducer has a nodal plane midway between its ends and is supported at this nodal plane.

摘要： An ultrasonic surgical aspirator having an improved irrigation/aspiration manifold and components to facilitate quick connections of the irrigation and aspiration lines to a handpiece. In combination with a handle assembly (31) having an ultrasonic vibrator (32) for vibrating an ultrasonic tip (34) and a nosecone (33), a nosecone extension (42) defining a rotating joint (43) for connection to the nosecone in an articulating joint for connection to a rigid or flexible flue (47, 49). The nosecone extension further defines an irrigation cowl (77) having an irrigation port for receiving an irrigation connector (77) for connecting the irrigation fluid to the nosecone extension for passage of irrigation fluid through the nosecone extension and a flue about the surgical tip. An aspiration tubulation connector (71) adapted to securely fit a slot through the nosecone and nosecone extension connects an aspiration port (37) on the tip to the aspiration tube (76) for connection to a pump into a discard.

摘要： An apparatus and method for assembly and disassembly of interchangeable surgical acoustic members includes a fixture (50) for securing by a key a handpiece to which a tip and/or extender is attached. A torquing wrench (70) has a tightening head (73) and an untightening head (74) on the same body (71) wherein the tightening head (73) permits torquing of the tip and/or extender to a predetermined tightening torque in cooperation with a socket (92, 93) having a central bore (92a, 93a) therethrough so that the wrench (70) and socket (92, 93) may be slid over an axially elongated combination and used at a point intermediate along the length thereof. In use, the handpiece is secured in the handpiece fixture (50) and receives the tip and/or extender in handtightened condition to be torqued to a predetermined limit by the torquing wrench (70) while secured against rotation in the handpiece fixture (50). A table support structure (102) for supporting a handpiece fixture for an alternative operation is also disclosed.

摘要： A method and apparatus for periodically interrupting ultrasonic power applied to a ultrasonically vibrating tip (11) to control its amplitude between high and low or zero amplitudes with a selectable duty cycle and repetition rate provides enhanced fragmentation and improves surgical control. The duty cycle may also vary as a function of a remotely sensed parameter such as tissue temperature.

摘要： A tool holder (90) preferably for an ultrasonic endodontic apparatus includes an eccentric member (98) in the holder to secure the butt end of a tool thereon by a camming action during limited rotation of a cam member (98). The tool holder also includes an irrigating fluid passage (94) located proximate to, but remote from, a tool-receiving bore in the tool holder to direct irrigating fluid onto the tool. An eccentric cam (98) is mounted in a cross-bore (99) within the tool holder, located relative to a tool-receiving bore having a predetermined longitudinal depth, so that a camming action of the eccentric cam longitudinally seats the tool (119) deep in the bore (100) while securing it there by the cam upon limited rotational motion of the cam. The cam includes tool pads (114, 118) for receiving mating surfaces of a bifurcated wrench.

摘要： An improved tooth cleaning system in which soluble abrasive cleaning powder fed from a fluid-tight chamber and entrained in a stream of air is directed against the tooth surface to be cleaned from a manually controlled handpiece includes an improved air supply and control system having a first conduit for supplying air under pressure to the handpiece, a second conduit connected to the first for supplying air under pressure into the bottom portion of the fluid-tight chamber for entraining cleaning powder to be discharged through an outlet opening in the fluid-tight chamber, a third conduit connected to the first and to the fluid-tight chamber for directing a flow of air into the chamber at a point above the level of the cleaning powder in the chamber, a flow restricter and air filter connected in the third conduit and with the air-filter being located in the fluid-tight chamber for filtering air flowing into and out of the system through the third conduit, fourth conduit connected to the outlet from the fluid tight chamber and to the first conduit downstream of the connection with the first and second conduits whereby air and cleaning powder discharged from the fluid-tight chamber will be mixed with the air flowing from the first conduit for delivery to the handpiece, a pinch valve flow controller for controlling the flow of air and cleaning powder through the fourth conduit, and one-way renewable air filters connected in the first and second conduits with the renewable filters including a check valve to prevent the reverse flow of air through the filters.

摘要： An optical system for a surgical ophthalmic instrument 10 using a YAG laser reduces the size of the components and facilitates their combination with a binocular microscope 11. A parallel plate beam splitter 22 splits a beam 21 from a visible light He-Ne laser 20 into equal and separated He-Ne beams 21a and 21b. A pair of expanders 27 and 37 diverge the He-Ne beams and a beam 30 from the YAG laser 15. The diverging beams are combined on a coincident optical path, which is collimated and coincided with the optical path of microscope 11 between its binocular head 42 and objective 43. There, a mirror 50 coated to reflect the YAG laser light also has a pair of spaced-apart regions 51a and 51b with a second coating to reflect both the He-Ne beams 21a and 21b so that all laser light converges on the patient's eye. The central mirror region 52 is transparent to visible light so that most of the light reflected from the patient's eye is visible to the surgeon. The lasers and other components are mounted on an optical plate 25 secured to a lower support 12 of microscope 11 where controls are convenient and accuracy is assured.
