Abstract
Surgical stereo vision systems and methods for microsurgery are described that enable hand-eye collocation, high resolution, and a large field of view. A digital stereo microscope apparatus, an operating system with a digital stereo microscope, and a method are described using a display unit located over an area of interest such that a human operator places hands, tools, or a combination thereof in the area of interest and views a magnified and augmented live stereo view of the area interest with eyes of the human operator substantially collocated with the hands of the human operator.
Claims18
A digital stereo microscope system for use in microsurgery, the digital stereo microscope system comprising:
- a unit comprising a display on a front side and one or more sensing elements on a back side;
- a processing system communicatively coupled to the unit and configured to provide a magnified and augmented live stereo view of the area of interest,
- wherein a flexible arm is coupled to the unit, wherein the unit is manually movable and positioned using the flexible arm to fix the unit over an area of interest for the microsurgery, and wherein the unit is positioned between a surgeon and hands, tools, or combination thereof of the surgeon such that the unit is substantially in a line of sight of the surgeon and the area of interest and the surgeon directly views the display with both eyes;
- and
- one or more sensors and compensators associated with the flexible arm, wherein the processing system is configured to compensate images from the one or more sensing elements to compensate movement in the unit, based on data from the one or more sensors and compensators.
A digital stereo microscope method for use in microsurgery, the digital stereo microscope method comprising:
- providing a unit comprising a display on a front side and one or more sensing elements on a back side;
- providing a processing system communicatively coupled to the unit and configured to provide a magnified and augmented live stereo view of the area of interest,
- wherein a flexible arm is coupled to the unit, wherein the display and image sensor unit is manually movable and positioned using the flexible arm to fix the unit over an area of interest for the microsurgery, and wherein the unit is positioned between a surgeon and hands, tools, or combination thereof of the surgeon such that the unit is substantially in a line of sight of the surgeon and the area of interest and the surgeon directly views the display with both eyes;
- and
- providing one or more sensors and compensators associated with the flexible arm, wherein the processing system is configured to compensate images from the one or more sensing elements to compensate movement in the unit, based on data from the one or more sensors and compensators.
A surgical microscope system, comprising:
- a unit comprising a display on a front side and one or more sensing elements on a back side;
- a processing system communicatively coupled to the unit and configured to provide a magnified and augmented live stereo view of the area of interest;
- a flexible arm is coupled to the unit, wherein the unit is manually movable and positioned using the flexible arm to fix the unit over an area of interest for the microsurgery, and wherein the unit is positioned between a surgeon and hands, tools, or combination thereof of the surgeon such that the unit is substantially in a line of sight of the surgeon and the area of interest;
- a pair of glasses wearable by the surgeon for viewing the display, wherein the surgeon directly views the display with both eyes using the pair of glasses;
- and
- one or more sensors and compensators associated with the flexible arm, wherein the processing system is configured to compensate images from the one or more sensing elements to compensate movement in the unit, based on data from the one or more sensors and compensators.
