Abstract
A surgical microscope system having a head unit microscope assembly and a foot control assembly in operative communication with the head unit microscope assembly. The head unit microscope assembly being configured to selectively couple to a floor stand assembly such that the that the head unit microscope assembly can be positioned in a desired operative location by the user. The head unit microscope assembly including one or more of: a mounting adaptor, an XY directional stage, a tilt drive, a focus drive; a microscope subassembly, and/or an illumination system.
Claims31
A surgical microscope system, comprising:
- an illumination system comprising a plurality of light sources configured for illumination of targeted tissue area of a patient, the plurality of light sources comprising a coaxial light source and a pair of oblique light sources that are configured to illuminate the targeted tissue area at a selected light intensity level, wherein the coaxial light source forms a beam of divergent light that is configured to provide a wide dispersion of light energy on the targeted tissue area, wherein each of the plurality of light sources comprises a light-emitting diode (LED) having a large light emitting surface (LES) area of greater than about 20.0 mm2;
- and
- a processing system, wherein an at least one memory of the processing system is configured to store program instructions, and wherein the at least one memory of the processing system is configured to store program instructions that when executed cause the intensity of light energy incident on the targeted tissue area provided by the plurality of light sources to be selectively configured such that the ratio of light between the coaxial light source and the pair of oblique light sources are maintained at a user preference light ratio level setting.
A surgical microscope system, comprising:
- a processing system, wherein an at least one memory of the processing system is configured to store program instructions;
- a plurality of light sources configured for illumination of targeted tissue area of a patient, the plurality of light sources comprising a coaxial light source and a pair of oblique light sources that are configured to illuminate the targeted tissue area at a selected light intensity level, wherein the coaxial light source forms a beam of divergent light that is configured to provide a wide dispersion of light energy on the targeted tissue area, wherein each of the plurality of light sources comprises a light-emitting diode (LED) having a large light emitting surface (LES) area of greater than about 20.0 mm2;
- wherein the at least one memory of the processing system is configured to store program instructions that when executed adjust the spectral makeup of the total light generated by the coaxial light source and the pair of oblique light sources to a desired spectrum of incident light in order to obtain a level of desired red reflex from the light illumination incident on an eye of the patient.

- and
- a processing system, wherein an at least one memory of the processing system is configured to store program instructions, wherein the at least one memory of the processing system is configured to store program instructions that when executed adjust the spectral makeup of the total light generated by the coaxial light source and the pair of oblique light sources to a desired spectrum of incident light in order to obtain a level of desired red reflex from the light illumination incident on an eye of the patient.
