Ultrasonic surgical handpiece

A TL/T tip is made by scaling down the dimensions of an L/T tip by the ratio of the TL/T frequency to the L/T frequency so that the TL/T tip can operate by excitement from a transducer at the same frequency that would have produced L/T motion in the L/T tip. A reductive resonator may be included between the transducer and the TL/T tip.

Tooth whitening device for whitening teeth using sonochemistry includes a body, and an ultrasonic transducer provided in the body. The ultrasonic transducer is configured for producing ultrasonic waves in the range of 20-100 kHz, and good results have been achieved with ultrasonic waves at a frequency of 40 kHz. There is an ultrasonic horn provided on the body, and the ultrasonic horn is operatively connected with the ultrasonic transducer. A liquid retaining element is provided on the ultrasonic horn, and the liquid retaining element is configured for retaining a liquid tooth whitening composition against a user's teeth. The liquid retaining element may be a sponge or a replaceable pad, such as a foam pad.

Method and device for whitening teeth using sonochemistry

A surgical instrument comprising a sleeve, a electro-mechanical transducer containing a hollow passage for producing mechanical vibrations in response to a magnetic field, an ultrasonic horn mechanically connected to the transducer, containing a hollow passage communicating with that in the transducer, for amplifying the produced vibration such that dissection of biological tissue is produced and a tip having a hollow passage, mechanically connected to the horn and whose passage communicates with that in the horn, for contacting such tissue, connection of the passage to a source of vacuum and a sheath connected to the instrument and surrounding the tip and horn, with a connection to a source of irrigating fluid and a structure for mounting the transducer and horn within the sleeve permitting retracting and extension of the transducer and horn within and with respect to the sheath. The transducer, horn and tip are immersed in the irrigating solution. The instrument may also include a telescope for viewing the tissue contacting site and provision for electrifying the tip with electro-cauterizing current as well as provision for the use of endo-laser fulguration of the site.

Retractable ultrasonic endoscopic aspirator

An ultrasonic tissue dissection system providing combined longitudinal and torsional motion of tips, together with irrigation and aspiration, for improved cutting of resistant biological tissue. The system permits the use of common and inexpensive electro-mechanical transducers for the production of such motion through the use of longitudinal-torsional resonators.

Longitudinal-torsional ultrasonic tissue dissection

A tubular resonant mechanical horn having a contoured inner surface such that, under vibration, an output radial displacement is obtained on the outer surface of horn that is substantially uniform over its entire surface, for producing effects useful in continuous processes. The horn does not contain a node of motional displacement.

Apparatus using the temperature sensitive elastic property of super elastic alloys is disclosed for measuring temperate using, and controlling the vibration in response to temperature of, resonant electro-mechanical systems in commercial, industrial and medical applications.

Superthermoelastic resonators

A method for the melting and removal of thermoplastic prosthetic implant cement through the use of an aspirating ultrasonic surgical device is provided. The instrument defines a centrally located bore which expands in diameter from a surgical tip in the direction of aspirant flow for a length equal to at least 1/4 the wavelength corresponding to the resonant frequency of the device so as to prevent blockage by solidified cores of cement. Alternatively, the bore expands from a first uniform diameter extending from the tip end to a second uniform diameter. A compound taper at the tip end minimizes contact between the outer surface of the tube at the tip end. A novel transducer cooling system is provided by incorporating a thermally conductive, electrically insulating material between the piezoelectric crystal (which generates heat as a byproduct) and a hollow metal bolt which defines a central bore through which cooling irrigant flows to conductively remove heat generated by the crystal.

Tapered tip ultrasonic aspiration method

This invention relates to a surgical apparatus having four general embodiments: (1) the use of an ultrasonic vibrator and a radio frequency generator to simultaneously cut and cauterize tissue, (2) the use of an ultrasonic vibrator to cut tissue coupled with the independent use of a radio frequency generator to cut tissue, (3) the exclusive use of a radio frequency generator to cut and cauterize tissue, and (4) the use of a laser to fulgerate tissue. An aspiration system is preferably combined with these embodiments to facilitate surgery and biopsy.

Endoscopic electrosurgical apparatus

Apparatus including a receptacle mounted on the handpiece of ultrasonic apparatus which utilizes ultrasonic energy for removing cores of thermoplastic material such as bone cement used to implant prostheses. The receptacle is placed in fluid communication with an acoustical conductor extending through the apparatus and a tubular tip provided at the end of the conductor which tip is vibrated ultrasonically to remove the cores, for example of bone cement. The receptacle is connected to a source of suction, and the cores are drawn or aspirated through the tubular tip, the acoustical connector, and into the receptacle. A filter may be provided in the receptacle to assure that cores received in the receptacle are not drawn or aspirated out of the receptacle through flexible tubing which interconnects the receptacle to a source of suction.
