Embodiment Construction

[0038] The present disclosure relates generally to stereoscopic visualization cameras and platforms. A stereo visualization camera may be referred to as a digital stereo microscope ("DSM"). The example camera and platform are configured to integrate microscope optics and video sensors into a self-contained head unit that is more robust than prior art microscopes such as the surgical loupes 100 of FIG. 1 and the magnifying glass of FIG. Surgical microscope 200) is significantly smaller, lighter, and more manoeuvrable. Example cameras are configured to transmit stereoscopic video signals to one or more television monitors, projectors, holographic devices, smart glasses, virtual reality devices, or other visual display devices within a surgical environment.

[0039] A monitor or other visual display device may be positioned in the surgical environment so as to be easily within the surgeon's line of sight while the patient is being operated on. This flexibility enables surgeons ...

Abstract

A stereoscopic visualization camera and platform are disclosed. An example stereoscopic visualization camera includes a first plurality of lenses positioned along a first optical path and a first image sensor to record a first image stream of a target site from light in the first optical path. The stereoscopic visualization camera also includes a second plurality of lenses positioned along a second optical path, parallel to the first optical path, and a second image sensor to record a second image stream of the target site from light in the second optical path. The stereoscopic visualization camera also includes a processor configured to reduce spurious parallax between the first and second images streams by selecting pixel sets of pixel grids of the first and second image sensors such that zoom repeat points ('ZRP') are located at a center of the respective pixel grids.

Description

technical field [0001] The present disclosure relates generally to surgical cameras, and more particularly to stereo cameras and stereo visualization platforms for microsurgical applications. Background technique [0002] Surgery is an art. Accomplished artists create works of art that are far beyond the reach of the average person. Using a paintbrush, the artist transforms cans of paint into vivid images that evoke strong and unique emotions in the viewer. Artists take ordinary words on paper and turn them into dramatic and uplifting performances. Artists master instruments and make them make beautiful music. Similarly, surgeons use seemingly ordinary scalpels, tweezers, and probes to create life-altering biological miracles. [0003] Like artists, surgeons have their own methods and preferences. Aspiring artists are taught the basics of their craft. Beginners often follow prescribed methods. As they gain experience, confidence and knowledge, they develop their own u...
