Abstract

A system and method for a reconfigurable surgical microscope is disclosed. The reconfigurable microscope includes an eyepiece; a relay lens system optically coupled to the eyepiece; a zoom lens system optically coupled to the eyepiece and the relay lens system; an illumination unit; and an objective lens capable of being repositioned between a first objective lens position and a second objective lens position, the first objective lens position comprising a slot located between the zoom lens system and the illumination unit and the second objective lens position comprising a slot located such that the illumination unit is located between the second objective lens position and the zoom lens system.

First claim

The invention claimed is:

1. An automated surgical microscope configuration system, comprising:
a processor;
a position sensor coupled to the processor;
a reconfigurable surgical microscope coupled to the position sensor, the reconfigurable surgical microscope including:
an eyepiece;
a relay lens system optically coupled to the eyepiece;
a zoom lens system optically coupled to the eyepiece and the relay lens system;
an illumination unit; and
a reconfigurable objective lens capable of being repositioned between a first objective lens position and a second objective lens position, the first objective lens position comprising a first slot located between the zoom lens system and the illumination unit and the second objective lens position comprising a second slot located such that the illumination unit is located between the second objective lens position and the zoom lens system; and

an actuator coupled to the processor and the reconfigurable objective lens and configured to move the reconfigurable objective lens into either the first lens position or the second lens position.

2. The automated surgical microscope configuration system of claim 1 , wherein the reconfigurable objective lens comprises multiple movable lenses.

3. The automated surgical microscope configuration system of claim 1 , wherein the position sensor comprises multiple position sensors associated with at least one of the first objective lens position or the second objective lens position.

4. The automated surgical microscope configuration system of claim 1 , wherein the actuator comprises multiple actuators.
