Patent number: 11918245Abstract: 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.Type: GrantFiled: October 3, 2019Date of Patent: March 5, 2024Assignee: Kogent Surgical, LLCInventors: Steven J Apperson, Johanna L Bryan, David G Wuchinich

Publication number: 20200108186Abstract: 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.Type: ApplicationFiled: October 4, 2019Publication date: April 9, 2020Inventors: Gregg D Scheller, Steven J Apperson, Johanna L Bryan, David G Wuchinich
