An endoscope having an outer shaft member with a distal end forming a distal end of the endoscope and an optics member with a distal end. The optics member is located inside the outer shaft member. The optics member defines a viewing direction of the endoscope, the viewing direction being tilted relative to a longitudinal axis of the outer shaft member. The endoscope further has optical fibers comprising an optically transparent material and provided and conditioned for the transport of illumination light to the distal end of the endoscope. The endoscope further has a segment located between an outer surface region of the distal end of the optics member and an inner surface region of the distal end of the outer shaft member. The orientation of distal ends of the optical fibers is defined by the segment.

The subject matter discloses a medical imaging device, comprising a rigid housing, at least two camera units located within said rigid housing, capturing images of different directions of view and a maneuver mechanism configured to change the physical orientation of a camera of the at least two camera units

An endoscope pipe with a central, elongated observation window on the distal end, whereby several light outlet openings for fiberoptic end surfaces are positioned close to the observation window for illuminating the angle area observed through the observation window and the light outlet openings are positioned asymmetrically in relation to the longitudinal extension of the observation window and/or the fiberoptic end surfaces are held in the light outlet openings in such a way that light is beamed from the fiberoptic end surfaces into the angle area in various directions.

An endoscope distal end portion includes a longitudinal axis and is provided at a distal end of an insertion section, and the endoscope distal end portion includes an observation window provided on a side with respect to an insertion direction of the insertion section, an illumination window disposed on proximal end side of the observation window, and a reflector disposed on distal end side of the observation window to include a predetermined angle with respect to the longitudinal axis, and configured to reflect illumination light outputted from the illumination window, to a rear observation region.

The invention resides in a laparoscope, or camera, for a medical procedure, having a body having a distal end for locating in a patient and a proximal end for handling the laparoscope outside the patient. A camera is provided together with a light source at the distal end. An operable interface is provided adjacent the proximal end, for operating the camera and/or light source. A processor and data storage are located in the body and operable to provide an interface for managing the camera, light source and recording images. The laparoscopic camera can be self-contained such that it is operable without cables or external support devices. It can manage image recording, calibration and storage all within the camera. The invention also resides in a case for use with the laparoscope.

The disclosure relates to an endoscopic light source that includes a first emitter. The first emitter may emit light of a first wavelength at a dichroic mirror which reflects the light of the first wavelength to a plurality of optical fibers. The endoscopic light source further comprises a second emitter. The second emitter may emit light of a second wavelength at a second dichroic mirror which reflects the light of the second wavelength to the plurality of optical fibers. In one embodiment, the first dichroic mirror may be transparent to the light of the second wavelength, allowing the light of the second wavelength to pass through the first dichroic mirror.

An endoscope illumination device includes: an illumination optical system including an entrance surface disposed along a circumferential direction centered on a predetermined axis and provided at one-end side in the direction of the predetermined axis, an emission surface positioned at an outermost side in a radial direction with respect to the predetermined axis and radially emitting illumination light entering from the entrance surface, a diffusion surface disposed at an intermediate position of an optical path of the illumination light between the entrance surface and the emission surface and transmitting and diffusing the illumination light; and a light emitting portion disposed closer to the one-end side than the entrance surface is and emitting, toward the entrance surface, the illumination light substantially in the direction of the axis.

Methods and systems for acquiring and/or projecting images from and/or to a target area are provided. Such a method or system can include an optical fiber assembly which may be driven to scan the target area in a scan pattern. The optical fiber assembly may provide multiple effective light sources (e.g., via a plurality of optical fibers) that are axially staggered with respect to an optical system located between the optical fiber and the target area. The optical system may be operable to focus and/or redirect the light from the multiple light sources onto separate focal planes. A composite image may be generated based on light reflected from and/or projected onto the separate focal planes. The composite image may have an extended depth of focus or field spanning over a distance between the separate focal planes while maintaining or improving image resolution.

An endoscope device includes a signal processing unit that processes a captured image signal, which is obtained by imaging a subject through an imaging optical system including an objective lens of an endoscope, to generates captured image, an auxiliary measurement light emitting unit that emits planar auxiliary measurement light from the distal end part, a display control unit that causes a display unit to display the captured image including an intersection line formed in a portion where a plane formed by the auxiliary measurement light intersects the subject. The auxiliary measurement light emitting unit emits the auxiliary measurement light in a state where the plane and an optical axis intersects each light at one specific point on the optical axis of the objective lens. A distance from a distal end part of the objective lens of the one specific point is 5 mm or more and 20 mm or less.

An endoscope device includes an imaging element that images a subject through an imaging optical system including an objective lens disposed at a distal end part of the endoscope, a signal processing unit that processes a captured image signal, which is obtained by imaging the subject by the imaging element, to generate a captured image, an auxiliary measurement light emitting unit that emits planar auxiliary measurement light into a visual field of the imaging optical system from the distal end part, and a display control unit that causes a display unit to display the captured image including an intersection line formed in a portion where a plane formed by the auxiliary measurement light intersects the subject. The display control unit causes a scale serving as an index of the size of the subject to be displayed on the intersection line included in the captured image.
