Abstract

A surgical visualization system that can include a structured light emitter, a spectral light emitter, an image sensor, and a control circuit is disclosed herein. The structured light emitter can emit a structured pattern of electromagnetic radiation onto an anatomical structure. The spectral light emitter can emit electromagnetic radiation including a plurality of wavelengths. At least one of the wavelengths can penetrate a portion of the anatomical structure and reflect off a subject tissue. The image sensor can detect the structured pattern of electromagnetic radiation reflected off the anatomical structure and the at least one wavelength reflected off the subject tissue. The control circuit can receive signals from the image sensor, construct a model of the anatomical structure, detect a location of the subject tissue, and determine a margin about the subject tissue, based on at least one signal received from the image sensor.

Claims20

Dependent claims

A surgical system, comprising:

a display;
a visualization system configured to scan the anatomy of a patient, comprising:
a structured light emitter configured to emit a structured pattern of electromagnetic radiation onto an anatomical structure;
a spectral light emitter configured to emit electromagnetic radiation comprising a plurality of wavelengths, wherein at least one wavelength of the plurality of wavelengths is selected to penetrate a portion of the anatomical structure and reflect off a subject tissue;
and
an image sensor configured to detect the structured pattern of electromagnetic radiation reflected off the anatomical structure and the at least one wavelength reflected off the subject tissue;
and
a surgical hub operably coupled to the visualization system and the display, wherein the surgical hub comprises a processor and a memory communicatively coupled to the processor, wherein the memory stores instructions executable by the processor to:
generate visualization data based on the scanned anatomy;
identify anatomical organs of the patient based on the generated visualization data;
generate virtual 3D constructs of the anatomical organs based on the generated visualization data;
display the virtual 3D constructs of the anatomical organs on the display;
identify anatomical structures based on the generated visualization data;
generate virtual 3D constructs of the anatomical structures based on the generated visualization data;
display the virtual 3D constructs of the anatomical structures on the display;
and
overlay a surgical procedure plan on the display.
