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 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.

An electronic system for a surgical instrument is disclosed. The electronic system comprises a main power supply circuit configured to supply electrical power to a primary circuit. A supplementary power supply circuit configured to supply electrical power to a secondary circuit. A short circuit protection circuit coupled between the main power supply circuit and the supplementary power supply circuit. The supplementary power supply circuit is configured to isolate itself from the main power supply circuit when the supplementary power supply circuit detects a short circuit condition at the secondary circuit. The supplementary power supply circuit is configured to rejoin the main power supply circuit and supply power to the secondary circuit, when the short circuit condition is remedied.

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 controller may receive electrical signal associated with an activation of at least one user-actuated input device electrically coupled to the controller and override the operating mode of the surgical instrument upon receiving the electrical signal.

A light assembly is configured to selectively illuminate an operating region in a surgical suite. The assembly comprises a plurality of lighting modules comprising a plurality of light sources configured to emit light. The assembly further comprises at least one imager configured to capture image data disposed in at least one of the lighting modules. An articulating head assembly is configured to support each of the lighting modules. The articulating head assembly comprises a plurality of actuators configured to rotate each of the lighting modules about a first axis and a second axis. The assembly further comprises a controller. The controller is configured to scan the image data for at least one region of interest comprising at least one of a shaded region and a contaminated region.

A method for visualizing tissue of a subject includes receiving a first series of first imaging modality frames generated by imaging a region of tissue of the subject, and a first series of second imaging modality frames generated by imaging the region of tissue; displaying the first series of first imaging modality frames in combination with the first series of second imaging modality frames; storing a plurality of first imaging modality frames and a plurality of second imaging modality frames of the first series of second imaging modality frames in a memory; receiving a second series of first imaging modality frames generated by imaging the region of tissue; and displaying the second series of first imaging modality frames in combination with one or more of the second imaging modality frames of the first series of second imaging modality frames stored in the memory for visualizing the region of tissue.

A medical observation apparatus including: an arm including a plurality of links connected to each other via a joint, the arm having at least three or more degrees of freedom implemented by a rotation operation about a rotation axis; an imaging device supported by the arm; and an arm controller that controls an operation of the arm. When a posture of the arm is in a predetermined state, and when a predetermined input for moving the arm about a rotation axis orthogonal to a second axis that is a second rotation axis from a side of the arm on which the imaging device is supported and a third axis that is a third rotation axis from the side of the arm on which the imaging device is supported is detected, the arm controller makes one of the links corresponding to the third axis rotate about the third axis.

There is provided a wearable medical observation apparatus used by being worn on a head of a user, including: a first observation section having a configuration enabling a first observation of an observation target through an optical system including at least an objective lens; a second observation section having a configuration enabling a second observation of an observation target by a first medical observation image in which the observation target is imaged by a first imaging device; and a control section configured to control an observation state of the observation target.

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.
