Patent number: 11839390Abstract: A two phase method for reducing the formation of biofilm includes an evacuation of ambient air from a region about the surgical or treatment site, to extract airborne or aerosolized bacteria ejected from the site by the treatment. The extracted bacteria are prevented from settling back onto the cleansed tissue surface, thus at least reducing colonial bacteriological growth and concomitantly exuded biofilm material. A second phase involves the attachment of one or more ultrasonic transducers to the patient over or near a surgical treatment site after the surgery is terminated. Each applied ultrasonic transducer is used to vibrate the patient's tissues at the treatment site to disrupt biofilm formation.Type: GrantFiled: April 13, 2021Date of Patent: December 12, 2023Assignee: MISONIX, LLCInventors: Paul Mikus, Scott Isola, Dan Voic, Scott Ludecker, Alexander Darian

Publication number: 20230210549Abstract: An ultrasonic surgical instrument includes a handpiece casing and an electromechanical transducer assembly disposed inside the handpiece casing, where the transducer assembly includes a front driver and the transducer assembly has a longitudinal axis. A probe is operatively connected to the front driver at an acute angle to the longitudinal axis of the transducer assembly. A sheath surrounds the probe and is connected at a proximal end to the handpiece casing. The sheath is attached to the casing by a twist quick release coupling. A diaphragm seal inside the proximal end of the sheath blocks liquid irrigant in a cylindrical space between the sheath and the probe from penetrating proximally of a port feeding irrigant to the space. The front driver is geometrically configured to enable an angled connection of probe to handpiece proximate a nodal plane.Type: ApplicationFiled: January 7, 2022Publication date: July 6, 2023Inventors: Dan VOIC, Alexander DARIAN, Scott ISOLA, Lawrence AGTUCA

Patent number: 11298434Abstract: An ultrasonic medical probe has a horn or shaft, a shank at a proximal end of the shaft, a probe head at a distal end of the horn or shaft, opposite the shank, and at least one polymeric component fixed to at least one of the horn or shaft, the shank, and the probe head. The shank is provided at a proximal end opposite the horn or shaft with an externally threaded connector for attaching the probe to a source of ultrasonic vibratory energy. The polymeric component is of a composition that transmits and is essentially impervious to ultrasonic vibratory energy but that degrades or decomposes upon exposure to a source of extreme energy (other than ultrasonic vibratory energy), rendering the probe inoperative for use.Type: GrantFiled: July 9, 2015Date of Patent: April 12, 2022Assignee: MISONIX, INCORPORATEDInventors: Scott Isola, Alexander Darian, Dan Voic, Ronald Manna

Patent number: 10869686Abstract: A surgical method utilizes a cutting blade having a thickness along a cutting edge of between about 0.0005 inch and about 0.020 inch and preferably between about 0.001 inch and 0.010 inch. The blade is moved in contact with relatively hardly tissues which are disposed adjacent to softer tissues at a surgical site in a patient. The blade is ultrasonically vibrated during the moving of the blades, whereby the hard tissue is cut with a modicum of damage being inflicted on the soft tissue.Type: GrantFiled: February 5, 2019Date of Patent: December 22, 2020Assignee: MISONIX, INCORPORATEDInventors: Dan Voic, Alexander Darian, Christian Ritter, Mircea Paraschiv

Patent number: 10398463Abstract: An ultrasonic tool or instrument has a probe shaft with a linear proximal end portion and a linear distal end portion disposed at an angle relative to one another and joined at a bend in the shaft. A coupling is provided at a proximal end of the shaft for connecting the probe to a source of ultrasonic vibrational energy. A head provided at a distal end of the shaft extends eccentrically in a transverse direction to one side of the shaft. The head has an operative tip spaced laterally from the axis and is formed with at least one cutout for reducing mass of the head and concomitantly eccentric mass of the probe.
