Abstract

A surgical visualization system may capture images of an interior of a cavity of a patient with a plurality of cameras. Those images may subsequently be used to create a three dimensional point cloud representing the interior of the cavity of the patient. This point cloud may then be used as a basis for displaying a representation of the interior of the cavity of the patient, which representation may be manipulated or viewed from different perspectives without necessarily requiring movement of any physical camera.

Claims20

Dependent claims

A surgical visualization system comprising:

(a) a plurality of trocars, each trocar comprising a working channel;
(b) a plurality of cameras, wherein each camera from the plurality of cameras:
(i) has a corresponding trocar from the plurality of trocars;
(ii) is least partially inserted through the working channel of its corresponding trocar;
and
(iii) is adapted to capture images of an interior of a cavity of a patient when inserted through the working channel of its corresponding trocar;
(c) a processor, wherein:
(i) for each camera from the plurality of cameras:
(A) the processor is in operative communication with that camera;
and
(B) the processor is configured to receive a set of points corresponding to an image captured by that camera;
and
(ii) the processor is configured to generate a three dimensional point cloud representing the interior of the cavity of the patient based on combining the sets of points received from the plurality of cameras.
