  • Patent number: 4988334
    Abstract: 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 having an ultrasonic vibrator for vibrating an ultrasonic tip and a nosecone, a nosecone extension defining a rotating joint for connection to the nosecone in an articulating joint for connection to a rigid or flexible flue is provided. The nosecone extension further defines an irrigation cowl having an irrigation port for receiving an irrigation connector 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 adapted to securely fit a slot through the nosecone and nosecone extension connects an aspiration port on the tip to the aspiration tube for connection to a pump into a discard area.

  • Patent number: 4827911
    Abstract: A method and apparatus for periodically interrupting ultrasonic power applied to a ultrasonically vibrating tip to control its amplitude between high and low or zero amplitudes with a selectible 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.

  • Patent number: 4280123
    Abstract: A compact and economical circuit for a multitone horn employing a microcomputer. The system also includes an audio amplifier, a speaker, a power supply, and start control means. The start control means includes a common lead and a plurality of star leads. Connecting the common lead to a predetermined one of the start leads will initiate a predetermined one of the plurality of available tones. A selected one of the start leads may have priority to terminate any pre-existing signal and initiate an alternate signal. At least one of the start leads, including the priority start lead, may be coupled to programming means whereby the signal activated may be preprogrammed to be any selected one of the plurality of available signals. The power supply includes a pulse generator for resetting the microcomputer in response to initial application of power. The available tones include both percussive and non-percussive tones and the total number of available tones may be greater than the number of start leads.

  • Patent number: 3980997
    Abstract: Smoke detection apparatus including a pair of photoelectric cells which receive illumination selectively from a very low level light source. One of the cells is termed the "direct" cell because it is in the direct path or on the axis of a narrow conical beam of light emanating from the source, the other cell being termed the "reflected" cell because it receives a significant part of its light input upon reflection of light from smoke particles or the like as such particles are drawn into the path of the light beam. Under predetermined smoke conditions, i.e., when there is smoke obscuration of the light of 2% per foot (.01 optical density), an alarm signal is triggered. The very low level light source is a light-emitting diode which sensitively monitors the smoke obscuration; only a slight change in the illumination to the pair of photocells, connected in a sensing circuit, is required to produce the triggering signal.
