Ophthalmic Aspirator-Irrigator
Ophthalmic Aspirator-Irrigator
US Patent:
4705500, Nov 10, 1987
Filed:
Jul 17, 1986
Appl. No.:
6/886371
Inventors:
Harry G. Reimels - Braintree MA
David A. Walsh - Waltham MA
Michael J. Arsenault - Brant Rock MA
David A. Walsh - Waltham MA
Michael J. Arsenault - Brant Rock MA
Assignee:
Mentor O & O, Inc. - Norwell MA
International Classification:
A61B 1732
US Classification:
604 35
Abstract:
An ophthalmic aspirator-irrigator system for use during cataract surgery is disclosed. The system frees both hands of the surgeon for the surgical tasks and leaves the automatic operation of the system to a single control input operated by a foot pedal. The pedal controls both the aspiration and ejection functions as well as their respective speeds. The opthalmic aspirator-irrigator system essentially comprises a hand-held device, a control box operable by the foot pedal and a power cord connecting the device with the box. A source of fluid is connected via a tube to the device to effect the irrigation function. The control box includes a power source and a circuit coupled to the source and via the cord to the device. Preferably, the circuit includes a bridge output network controlled by a linear motion slide type potentiometer controlled by the foot pedal. The circuit further includes dual DC amplifiers and a pulse-width modulated gate circuit to operate the device bidirectionally with a smooth, continuous and varibale speed.
