Abstract: The present invention provides both continuously and discretely (54) variable spot size illuminators (10, 38, 42, 46) to provide a light spot on a treatment plane (28, 66) whose size can be adjusted while ensuring that the light fluence and the working focal distance remain substantially constant at all spot sizes. In a continuous illuminator, a focusing lens system (16, 18) is employed to form an image of a light source on an intermediate plane (20), and a variable aperture (22) is utilized to select a portion of the intermediate image. An objective lens system (26, 30, 64) then images the selected portion of the intermediate image onto a treatment plane (28, 66). A discrete illuminator employs a plurality of light shaping diffusers (56) to select the shape and/or size of an image formed on a treatment plane (66) from among a number of choices.

Abstract: Re: 2707 US F ess Mail EV 676196989 US FOOTSWITCH OPERABLE TO CONTROL A SURGICAL SYSTEM 5 The present invention provides a surgical footswitch that includes a base, a pedal, an encoder assembly, a wireless interface, and an internal power generator. The pedal mounts upon the base and pivots. The encoder assembly couples to the pedal. As the pedal pivots, the encoder assembly translates the mechanical signal of the pedal into a control signal based on the pedals position and/or orientation, The wireless 10 interface couples the encoder assembly to receive the control signal. The wireless interface also couples the surgical footswitch to a surgical console operable to control and direct surgical equipment. The wireless interface passes the control signal from the encoder to the surgical console, which then directs the surgical equipment based on the control signal. This wireless interface eliminates the tangle of wires or tethers, 15 which may be a hazard in the surgical theater. The internal power generator translates footswitch movement into stored energy to eliminate potential failures of the footswitch during a procedure and overcome the need to replace batteries within the footswitch.

Abstract: A filter and method for filtering an optical beam are disclosed. One embodiment of the filter is an optical filter for filtering an incident light beam, comprising an optically effective material characterized by: a light transmittance of less than 1% for wavelengths below 420 nm; and a light transmittance for wavelengths complementary and near complementary to wavelengths below 420 nm that, combined with the transmittance for wavelengths below 420 nm, will yield a filtered light beam having a luminosity of about 90% and an excitation purity of 5% or less. The complementary wavelengths can be wavelengths above about 640 nm, wavelengths above about 660 nm, and/or wavelengths from about 540 nm to about 560 nm. Further, in one embodiment the difference between the light transmittance just below 420 nm and the light transmittance just above 420 nm can be greater than 90%. Above 420 nm, in some embodiments, the light transmittance can be arbitrarily determined.

Above 420 nm, in some embodiments, the light transmittance can be arbitrarily determined. The optically effective material can be optical-grade glass, an optical-grade plastic or polymer, a thin-film dielectric coating, or an optical-grade glass or plastic coated with a dielectric coating. The optical filter can be mounted downstream of an illumination source exit aperture, wherein the illumination source produces the incident light beam, and upstream of a site to be illuminated by the filtered light beam. Alternatively, the optical filter can be operably mounted on a set of viewing optics of a surgical microscope to filter a reflected portion of a light beam produced by an illumination source and used to illuminate a site, such as a surgical site.
