A surgical visualization system includes multiple light sources, at least one optical sensor, at least one display device, and a controller. The controller is configured to control at least one light source to illuminate surgical tissue in a first manner, and control the optical sensor to receive an image from the surgical tissue illuminated in the first manner. The controller calculates a three-dimensional image from the tissue illuminated in the first manner. The controller is configured to control at the least one light source to illuminate surgical tissue in a second manner, and control the optical sensor to receive an image from the surgical tissue illuminated in the second manner. The controller calculates one or more subsurface critical anatomic structures from the tissue illuminated in the second manner and combines the display of the three-dimensional image and the anatomic structures on the at least one display device.

Various adaptive surgical visualization systems are disclosed. Surgical visualizations can compensate for obscured, incomplete, damaged, or interfered with portions of captured images by substituting those portions of the images with corresponding portions of other images. The other images could include images that were previously generated by the surgical visualization system or images that were generated using multispectral imaging techniques.

Various systems and methods of controlling a surgical visualization system and controlling devices according to the displayed point of view of the surgical visualization system are disclosed. The visualization system can allow users to change, update, or manipulate the displayed visualization utilizing overlapping or multiple images. Further, the controls and/or display screens of surgical instruments coupled to the visualization system can be adjusted to correspond to the orientation of the surgical instrument as visualized by the visualization system.

A visualization system including multiple light sources, an image sensor configured to detect imaging data from the multiple light sources, and a control circuit is disclosed. At least one of the light sources is configured to emit a pattern of structured light. The control circuit is configured to receive the imaging data from the image sensor, generate a three-dimensional digital representation of the anatomical structure from the pattern of structured light detected by the imaging data, obtain metadata from the imaging data, overlay the metadata on the three-dimensional digital representation, receive updated imaging data from the image sensor, and generate an updated three-dimensional digital representation of the anatomical structure based on the updated imaging data. The visualization system can be communicatively coupled to a situational awareness module configured to determine a surgical scenario based on input signals from multiple surgical devices.

A surgical system for use in a surgical procedure is disclosed. The surgical system includes a surgical visualization system and a control circuit. The configured to propose a portion of an organ to resect based on visualization data from the surgical visualization system, determine a first value of a non-visualization parameter of the organ prior to resection of the portion, and determine a second value of the non-visualization parameter of the organ after resection of the portion. Resection of the portion is configured to yield an estimated capacity reduction of the organ.

A surgical system for use in a surgical procedure is disclosed. The surgical system includes at least one imaging device and a control circuit configured to identify an anatomical organ targeted by the surgical procedure, generate a virtual three-dimensional (3D) construct of at least a portion of the anatomical organ based on visualization data from the at least one imaging device, identify anatomical structures relevant to the surgical procedure from the visualization data from the at least one imaging device, couple the anatomical structures to the virtual 3D construct, and overlay onto the virtual 3D construct a layout plan of the surgical procedure determined based on the anatomical structures.

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.

Various control systems for controlling a surgical system according to detected airborne particulate cloud characteristics are disclosed. The control systems can adaptively control various surgical devices, such as surgical instruments and smoke evacuators, according to the configuration or change in state of a surgical smoke cloud or another aerosol detected at a surgical site.

Various control systems for controlling a surgical system according to detected airborne particulate characteristics are disclosed.

A method of treating a sinus cavity of a subject includes advancing a distal portion of a light source through a drainage pathway of a sinus cavity and into the sinus cavity and visually observing a transdermal light emitted from the light source. A distal portion of a substantially rigid inner guide member of a balloon dilation catheter is advanced into the drainage pathway, the balloon dilation catheter including a movable shaft including a balloon that is slidably mounted on the substantially rigid inner guide member. The movable shaft and balloon are advanced distally over the substantially rigid inner guide member to place a portion of the balloon in the drainage pathway whereby the balloon is inflated.
