Publication number: 20210022763Abstract: An ultrasonic horn for use with an ultrasonic surgical handpiece including a resonator comprises a linear cutting blade at the distal end of a horn body. The linear cutting blade includes adjacent side-by-side rows of teeth each of which includes a land through which ultrasonic waves are propagated outwardly from the distal end. The lands of the rows of teeth are angled so that the propagated ultrasonic waves of one plurality of lands intersects the propagated ultrasonic waves from the other row of lands. Shear stress fields are developed at the intersections of the ultrasonic waves that will perform the cutting function on target tissue. An irrigation arrangement is also disclosed.Type: ApplicationFiled: October 12, 2020Publication date: January 28, 2021Applicant: Integra LifeSciences (Ireland) Ltd.Inventors: Daniel J. Cotter, Prakash Manandhar

Patent number: 9421027Abstract: An ultrasonic horn for use with an ultrasonic surgical hand piece including a resonator comprises a contacting annulus having a plurality of angled lands. The lands are alternated around the annulus such that adjacent lands have opposite angles. As a result of the adjacent angled lands, a shear stress field is developed in contacted tissue due to the promotion of refracted longitudinal ultrasonic waves propagating in different directions at the interface to the coupled tissue. The shear stress field enhances the fragmentation and removal rate of fibrous, elastic, and tenacious tissue. The horn is hollow permitting suction to be applied to the tissue for controlling tissue contact with the lands.Type: GrantFiled: August 26, 2013Date of Patent: August 23, 2016Assignee: Integra Lifesciences (Ireland) Ltd.Inventors: Daniel J. Cotter, Saurav V. Gupta, James P. O'Connor, Matthew F. Shinopulos

Patent number: 7871392Abstract: An ultrasonic horn assembly is configured so that irrigating fluid can be supplied only to a vibrating tip portion of the ultrasonic horn and so that suction aspiration can occur through a portion of the ultrasonic horn not in contact with the irrigating fluid. Controllers supplying irrigation fluid during a surgical procedure and controlling suction aspiration via monitoring of fluid level in the patient cavity are operatively coupled one to another to coordinate control of the fluid level in the patient cavity. Circuitry controlling power, frequency and amplitude of the tip of the ultrasonic horn occurring as a result of operation of a source of ultrasonic signal generating power controls either or both the supply of irrigation fluid and the suction aspiration so as to minimize damping of vibration of the tip of the ultrasonic horn. An optical viewing element is provided to view the tip of the ultrasonic horn.Type: GrantFiled: January 12, 2006Date of Patent: January 18, 2011Assignee: Integra LifeSciences (Ireland) Ltd.Inventor: Joe D.

Patent number: 7204825Abstract: An improved surgical console for use with a handheld tissue fragmentation device includes portable base having an upper portion. An adjustable display head is mounted to the upper portion of the base. The display head provides rotational and translational adjustment relative to the base. An aspiration system is coupled to the fragmentation device for aspirating fluid and tissue fragmented by the fragmentation device from a surgical site. An irrigation system is also coupled to the fragmentation device for supplying irrigating fluid to the surgical site for suspending tissue fragmented by the fragmentation device. A power system is coupled to the fragmentation device for energizing a transducer of the fragmentation device for fragmenting tissue.Type: GrantFiled: July 28, 2003Date of Patent: April 17, 2007Assignee: Integra LifeSciences (Ireland) Ltd.Inventors: William Wayne Cimino, Kristen Marie Morahan, Robert Lewis Blythe
