  • Publication number: 20240156483
    Abstract: An ultrasonic surgical handpiece may include an assembled handpiece, an ultrasonic tip, a tubing set, and an irrigation sleeve. The assembled handpiece may include an assembled motor, a housing sleeve, and a nosecone. The housing sleeve and the nosecone may be disposed over a portion of the assembled motor. The assembled motor may include an assembled transducer, a transducer sleeve, and an angled adaptor. The transducer sleeve may be disposed over a portion of the assembled transducer. The assembled transducer may include an amplifier, one or more piezoelectric rings, and a connector block. A surgeon may use the ultrasonic surgical handpiece to perform a portion of a surgical procedure.

  • Patent number: 11918245
    Abstract: An ultrasonic surgical handpiece has a motor having a torsional transducer assembly along a central axis of the surgical handpiece, the motor being configured for operative connection to a power source. A surgical attachment has a proximal end detachably connected to the motor and a distal end defining a working plane for engagement with biological tissue. The motor is configured to create a standing wave along the central axis in response to the application of an electrical current and voltage from the power source. The standing wave defines an alternating pattern of nodes and anti-nodes along the central axis, wherein a position of one of the anti-nodes along the center axis corresponds with the position of the working plane.

  • Publication number: 20200108186
    Abstract: An ultrasonic surgical handpiece includes a motor having a transducer assembly along a central axis of the surgical handpiece. The motor is configured for operative connection to a power source. A surgical attachment has a proximal end detachably connected to the motor and a distal end defining a working plane for engagement with biological tissue. A housing has a housing distal end, a housing proximal end, and a cavity configured to receive the motor and the surgical attachment. An irrigation path of the housing is configured to communicate irrigation fluid. The irrigation path has an inlet proximate the housing proximal end operatively connected to an irrigation fluid source, and an outlet proximate to the working plane. The irrigation path is separated from the housing cavity to prevent contact between the irrigation fluid and an operational portion of the surgical attachment.

  • Publication number: 20160367397
    Abstract: A multi-function capsulorhexis guide may include an outer rim, an inner rim, an anterior surface, a capsulorhexis guide, and an iris contact angle. The outer rim may include an outer rim medial edge, an outer rim lateral edge, and an outer rim thickness. The inner rim may comprise an inner rim medial edge, an inner rim lateral edge, and an inner rim thickness. The capsulorhexis guide may be configured to guide a tearing of a lens capsule. The anterior surface may include an adhesion geometry configured to temporarily fix the multi-function capsulorhexis guide to a portion of the lens capsule. The iris contact angle may be configured to retract an iris.
