Ultrasound Handpiece
US Patent:
6478766, Nov 12, 2002
Filed:
Jul 25, 2000
Appl. No.:
09/625294
Inventors:
James Y. Chon - Irvine CA
Assignee:
Alcon, Inc. - Hunenberg
International Classification:
A61B 1720
US Classification:
604 22
Abstract:
A handpiece having a set of longitudinally vibrating piezoelectric elements and which may additionally have an electric motor to provide rotational or oscillatory movement to the ultrasound horn. The piezoelectric elements are surrounded by a high temperature plastic sleeve, and the sleeve is filled with high temperature potting material. The potting material seal the piezoelectric elements against moisture without affecting the performance of the piezoelectric elements.
Ultrasound Handpiece
US Patent:
6602193, Aug 5, 2003
Filed:
May 22, 2002
Appl. No.:
10/153056
Inventors:
James Y. Chon - Irvine CA
Assignee:
Alcon, Inc. - Hunenberg
International Classification:
A61B 800
US Classification:
600439, 604 22, 600446
Abstract:
A handpiece having a set of longitudinally vibrating piezoelectric elements and which may additionally have an electric motor to provide rotational or oscillatory movement to the ultrasound horn. The piezoelectric elements are surrounded by a high temperature plastic sleeve, and the sleeve is filled with high temperature potting material. The potting material seal the piezoelectric elements against moisture without affecting the performance of the piezoelectric elements.
Ultrasound Handpiece
US Patent:
7645256, Jan 12, 2010
Filed:
Jul 18, 2005
Appl. No.:
11/183591
Inventors:
Mikhail Boukhny - Laguna Niguel CA, US
James Y. Chon - Irvine CA, US
Ahmad Salehi - Irvine CA, US
James Y. Chon - Irvine CA, US
Ahmad Salehi - Irvine CA, US
Assignee:
Alcon, Inc. - Hunenberg
International Classification:
A61B 17/20
A61B 17/32
A61B 17/32
US Classification:
604 22, 606169
Abstract:
A handpiece having at least one set of piezoelectric elements polarized to produce longitudinal motion when excited at the relevant resonant frequency. The piezoelectric crystals are connected to an ultrasonic horn to which a cutting tip is attached. The horn and/or the cutting tip contains a plurality of diagonal slits or grooves. The slits or grooves produce optimized torsional movement in the cutting tip when the piezoelectric crystals are excited at a second resonant frequency.
Ultrasonic Handpiece
US Patent:
7651490, Jan 26, 2010
Filed:
Aug 12, 2004
Appl. No.:
10/916675
Inventors:
Mikhail Boukhny - Laguna Niguel CA, US
James Y. Chon - Irvine CA, US
James Y. Chon - Irvine CA, US
Assignee:
Alcon, Inc. - Hunenberg
International Classification:
A61B 17/00
A61B 17/32
A61B 17/32
US Classification:
606 1, 606166, 606169
Abstract:
A handpiece having a single set of piezoelectric elements polarized to produce longitudinal motion when excited at the relevant resonant frequency. The piezoelectric crystals are connected to an ultrasonic horn to which a cutting tip is attached. The horn and/or the cutting tip contains a plurality of diagonal slits or grooves. The slits or grooves produce optimized torsional movement in the cutting tip when the piezoelectric crystals are excited at a second resonant frequency. Preferably, the two drive frequencies are not coincident, but provided in non-overlapping pulses.
Method Of Controlling A Surgical System Based On A Load On The Cutting Tip Of A Handpiece
US Patent:
7713202, May 11, 2010
Filed:
Jul 26, 2005
Appl. No.:
11/189492
Inventors:
Mikhail Boukhny - Laguna Niguel CA, US
James Y. Chon - Irvine CA, US
Ahmad Salehi - Irvine CA, US
Ann Yadlowsky - Irvine CA, US

Assignee:
Alcon, Inc. - Hunenberg
International Classification:
A61B 8/00
US Classification:
600439
Abstract:
A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines an approximate temperature of the eye using an irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power to the tip to compensate for increased loads on the tip.
Method Of Controlling A Surgical System Based On A Rate Of Change Of An Operating Parameter
US Patent:
7727193, Jun 1, 2010
Filed:
Jul 26, 2005
Appl. No.:

Assignee:
Alcon, Inc. - Hunenberg
International Classification:
A61M 1/00
US Classification:
604118
Abstract:
A surgical system that is able to sense the onset of an occlusion or other surgical event as well as when an occlusion breaks. To help avoid overheating of the tip, the system of the present invention predicts the temperature of the eye using irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system of the present invention monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip.
