A medical device such as a catheter or endoscope device includes an illumination light source having one or more organic light-emitting diodes (OLEDs). The OLEDs are energized to produce illumination light that is received by an image sensor or camera to produce images of tissue within a patient's body. A heat conductive polymer conducts heat away from the illumination light source.

A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

An illumination optical system for endoscope includes a rod lens as an optical element. The optical element includes a proximal end surface through which light enters and a distal end surface configured to emit the light. The distal end surface includes a diffusion region configured to diffuse emitted light. The diffusion region includes a plurality of concave portions and a plurality of peripheral regions surrounding the concave portions. Each concave portion includes a plurality of inclined surfaces as total reflection surfaces that are inclined with respect to the distal end surface. Each peripheral region includes a transmission surface configured to emit light totally reflected by the total reflection surfaces after passing through the proximal end surface and light not totally reflected by the total reflection surfaces.

A tip section of a multi-camera endoscope includes a front-pointing camera on a planar surface of a distal end of the tip section and two side-pointing cameras positioned on a cylindrical surface in proximity to the planar surface such that the side field of view provided by the two side-pointing cameras partially overlaps with the front field of view provided by the front-pointing camera. The tip section further includes a working channel configured for insertion of a surgical tool; and a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope is inserted.

The disclosed technology is directed to an endoscopic system comprises an endoscope having a shank and a photodetector engaged with one another and having an optical axis in a direction transverse to the shank. A display device for displaying an image acquired through the photodetector. A first probe is disposed in the endoscope on or around the optical axis at a position off the shank. A second probe is disposed in the endoscope at or near a position where the shank and the optical axis intersect with each other. A sensor for detecting the position of the first probe and the position of the second probe and a controller. The controller is configured to establish a first reference direction in an actual space. To acquire a direction from the second probe toward the first probe and to perform a process for indicating the first reference direction to a user.

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.

Multi-spectrum ring illuminated surgical cameras and scopes having a ring lens and a plurality of LEDs. The LEDs set behind an electronic imaging sensor (camera) and positioned radially about the longitudinal axis of the lens and/or scope.
