Portable handheld illumination system
First Claim
1. An ophthalmic surgical illumination system comprising:
- a power source configured and arranged to produce a power output of a desired power;
a portable ophthalmic surgical handpiece configured for intraocular illumination including;
an illumination system configured and arranged to emit light in response to power received from the power source, the illumination system comprising a plurality of light emitting diodes;
a microprocessor configured to generate a pulse signal for sending to the plurality of light emitting diodes, wherein the pulse signal is configured to maintain the portable ophthalmic surgical handpiece at a desired temperature by reducing heat dissipation by the plurality of light emitting diodes;
a temperature sensor connected to the microprocessor, the temperature sensor configured to provide feedback to the microprocessor to maintain the portable ophthalmic surgical handpiece at the desired temperature;
a coupling system configured and arranged to select a wavelength range of the light from the illumination system;
a coupling interface configured and arranged to couple light from the coupling system into one or more optical fibers; and
a fiber output stage including one or more optical fibers and configured and arranged to deliver light from the coupling interface to a surgical site;
wherein the plurality of light emitting diodes comprises a first light emitting diode configured to emit white light and a second light emitting diode configured to emit color light to enerate contrast ratios for surgical illumination.

Abstract
Illumination systems are described that can include one or more light sources, which can include LEDs, one or more lenses, and one or more optical fibers. A handheld, portable, and surgical intraocular illumination system is disclosed that is disposable, low-cost, and efficient. A surgeon can have direct control of turning the illuminator on and off and adjusting the intensity via a simple control ergonomically placed on the handpiece and/or voice activated control. A coupling is provided, such as through an endo-probe, which is coupled to the one or more light sources. A user input device can be included that is operable to transmit to a feedback controller a first signal based on a user-selected light intensity. The feedback controller can, in response to the first signal, transmit a second signal to the power source for altering the power provided by the power source to the illumination system.
