Offset illumination using multiple emitters in a fluorescence imaging system is described. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The emitter comprises a first emitter and a second emitter for emitting different wavelengths of electromagnetic radiation. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of a hyperspectral emission, a fluorescence emission, and/or a laser mapping pattern.

A cannula with a proximally mounted camera and proximally mounted light sources. The lighting sources have beam axes directed distally, toward a workspace at the distal end of the cannula. The light sources are coupled with focusing lenses, to reduce the beam angle of the lighting sources and reduce glare within the cannula tube.

Provided herein is a handle of a multi-camera endoscope, the handle includes a user interface activating unit which includes one or more external activating/control buttons, and an internal activating element, the handle optionally includes a converter configured to receive one or more parallel signals and transform the one or more parallel signals to one or more corresponding serial signals, wherein the parallel signals are output by one or more cameras of the endoscope. Further provided are endoscopes and medical imaging system which include the handle, as well as methods of use thereof.

An endoscope eyepiece grasping mechanism includes a base part with an arcuate wall portion defining a base part wall opening between the base part arcuate wall portion circumferential ends and a rotatable part with a rotatable arcuate wall portion defining a rotatable part arcuate wall opening between the rotatable arcuate wall portion circumferential ends. A path guide rotates and axially moves the rotatable part relative to the base part between an open and closes state. A biasing device acts to bias the rotatable part toward the closed state, whereby an endoscope eyepiece may be pushed through an endoscope eyepiece side opening to a coupled position in the open state and the rotatable part rotates to the closed state and moves axially toward the base to retain the eyepiece in the coupled position.

A camera head includes: a mount detachably connected to an eyepiece of an endoscope; an imager configured to capture a subject image emitted from the eyepiece; and a housing configured to house the imager, the housing including an interior portion including the imager thereinside, and an exterior portion arranged on an outer side of the interior portion, wherein the interior portion and the exterior portion are separated from each other in at least a part of an outer surface.

In a method of using a structured-light based system, real-time 2D images of a portion of a field of view are captured using an endoscope. A portion of an object in the field of view is illuminated with a structured light pattern, and light reflected from the field of view is detected. From the reflected light, a 3D image of the field of view is constructed, and 3D locations of points on a surface of the object are determined. The real time 3D spatial position of the endoscope and/or a surgical tool is determined. If a distance between the surface the endoscope and/or surgical tool, as determined using the 3D spatial position, falls below a predetermined distance, an alert is generated to notify a user.

A medical device includes an elongate device and one or more processors coupled to the elongate device. The elongate device includes a steerable distal end and a shape sensor located along a length of the elongate device. While the elongate device is being traversed through one or more passageways of a patient, the one or more processors are configured to, based on information from a sensor, monitor an insertion motion of the elongate device, detect a data collection event, and capture, in response to detecting the data collection event, a plurality of points along the length of the elongate device using the shape sensor. The data collection event is at least partially based on a change in direction of the insertion motion of the elongate device.

An endoscopic device includes a single-use cannula configured for insertion through a cervix into a uterus, a camera secured to a distal end region of the single-use cannula for acquiring images of the uterus, a connection hub secured to a proximal end region of the cannula, a reusable display configured to present the images acquired by the camera and that is securable to the connection hub, and a handle secured to the connection hub. The handle is pivotable between a first position in which the handle is stowed along the connection hub and arranged to prevent attachment of the reusable display to the connection hub and a second position in which the handle is deployed to an orientation that is antiparallel to the connection hub and arranged to permit attachment of the reusable display to the connection hub.

An endoscope that integrates the functions of an optical tower into a portable device, while eliminating the use of cords or cables that carry light, video signals or images, and power to the endoscope that may conflict with the movement of a surgeon and the members of the surgical team, or other operators in non-medical related applications is provided. The endoscope incorporates a camera, an image processor, a light source, a transmitter, a communication interface, a control interface, and one or more of a power source in a single portable unit or enclosure. The camera is in electrical communication with the image processor and supplies images and video to the image processor obtained via an elongated endoscope tube. The light source illuminates a viewing field of the endoscope via the elongated tube.

An imaging system, such as a surgical microscope, laparoscope, or endoscope or integrated with these devices, includes an illuminator providing patterned white light and/or fluorescent stimulus light. The system receives and images light hyperspectrally, in embodiments using a hyperspectral imaging array, and/or using narrowband tunable filters for passing filtered received light to an imager. Embodiments may construct a 3-D surface model from stereo images, and will estimate optical properties of the target using images taken in patterned light or using other approximations obtained from white light exposures. Hyperspectral images taken under stimulus light are displayed as fluorescent images, and corrected for optical properties of tissue to provide quantitative maps of fluorophore concentration. Spectral information from hyperspectral images is processed to provide depth of fluorophore below the tissue surface. Quantitative images of fluorescence at depth are also prepared. The images are displayed to a surgeon for use in surgery.
