An endoscopic imaging system for use in a light deficient environment includes an imaging device having a tube, one or more image sensors, and a lens assembly including at least one optical elements that corresponds to the one or more image sensors. The endoscopic system includes a display for a user to visualize a scene and an image signal processing controller. The endoscopic system includes a light engine having an illumination source generating one or more pulses of electromagnetic radiation and a lumen transmitting one or more pulses of electromagnetic radiation to a distal tip of an endoscope.

A surgical visualization feedback system is disclosed. The surgical visualization feedback system comprises an emitter assembly configured to emit electromagnetic radiation toward an anatomical structure. The emitter assembly comprises a structured light emitter configured to emit a structured light pattern on a surface of the anatomical structure and a spectral light emitter configured to emit spectral light capable of penetrating the anatomical structure. The surgical visualization feedback system further comprises a waveform sensor assembly configured to detect reflected electromagnetic radiation corresponding to the emitted electromagnetic radiation and a control circuit in signal communication with the waveform sensor assembly. The control circuit is configured to receive an input corresponding to a selected surgical procedure, determine an identity of a targeted structure within the anatomical structure based on the selected surgical procedure and the reflected electromagnetic radiation, and confirm the determined identity of the targeted structure through a user input.

A handheld dental instrument includes a casing provided with a holding portion to be held by a user, a reception unit provided on the casing to receive an operation from the user, and a control unit that controls a control target to perform a predetermined action in response to the operation received by the reception unit. The control unit performs a first control when the operation received by the reception unit from the user is a first operation, and performs a second control different from the first control when the operation received by the reception unit from the user is a second operation different from the first operation.

An electronic endoscope system includes: an electronic endoscope including, at a distal end portion, an image sensor that captures an image of a living tissue, and an ultrasound probe that applies ultrasonic waves to the living tissue to obtain an echo signal; a captured image processor including an image processing unit that processes an imaging signal output from the image sensor and generates a captured image; and an ultrasonic image processor including an ultrasonic image processing unit that processes the echo signal output from the ultrasound probe and generates an ultrasonic image, a noise detection unit that detects a periodic noise component included in the echo signal and generated at a level equal to or higher than a preset threshold level, and a noise suppression unit that performs processing of suppressing the detected noise component.

Proposed is a technology that enables a video signal (endoscopic image) output from an imaging unit to be processed without signal conversion according to an MIPI D-PHY standard. The present disclosure proposes an endoscope system including: an endoscope device that includes an endoscope-side connector unit; a processor that includes a processor-side connector unit; and an attenuation correction unit that corrects attenuation of a video signal from an image sensor disposed at a distal end portion of the endoscope device (FIG. 3).

A processor device includes an image signal acquisition unit, an image processing unit, a display control unit, an image storage control unit, and a user input reception unit. The image processing unit detects a region-of-interest, superimposes and displays a highlight display, and performs a setting change from a first highlight level setting value to a second highlight level setting value for changing a shape of the highlight display to be different. The second highlight level setting value is stored together with an endoscopic image.

An access device for a minimally invasive procedure can include a port body defining an instrument channel for a medical instrument, a radial extension extending at least partially outward from the body in a radial direction. The radial extension can extend from a distal end of the port body. The radial extension can define an imaging device cavity defined therein spaced from the port body and opening distally from the radial extension. The imaging device cavity can be configured to receive an imaging device therein for providing images within a field of view that is at least partially distal of the port body.
