The present disclosure relates to a multifunctional visual oral cleaning instrument that includes multiple functions of: a visual dental floss, and/or visual oral forceps, and/or a visual oral irrigator, and/or a visual toothbrush, and/or a detachable visual interdental brush. The dental floss, and/or oral forceps, and/or oral irrigator, and/or toothbrush, and/or interdental brush are/is connected with an oral viewer through a connecting mechanism. In one aspect, a visual oral irrigator includes an oral irrigator, an oral viewer, and a connecting mechanism. The oral irrigator is mounted on the oral viewer through the connecting mechanism. The oral viewer further includes a housing, a power supply system, a lighting system, a viewing system, a circuit system, and a switch.

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 in vivo endoscope illuminates tissue using multiple sources. Light from a short-range source exits a tubular wall of the endoscope through a first illumination region that overlaps an imaging region, and the light returns through the imaging region after reflection by tissue, to form an image in a camera. Light from a long-range source exits the tubular wall through a second illumination region that does not overlap the imaging region. The endoscope of some embodiments includes a mirror, and light from an emitter for the short-range source is split and reaches the first illumination region from both sides of an optical axis of the camera. Illuminating the first illumination region with split fractions of light results in greater uniformity of illumination, than illuminating directly with an un-split beam. The energy generated by each source is changed depending on distance of the tissue to be imaged.

A scope system is provided including an elongate tube with a distal portion and a lumen extending therethrough. The scope system also includes at least one accessory channel including a tubular structure with an accessory lumen extending therethrough, the at least one accessory channel movably disposed at least partially within the lumen of the elongate tube. The at least one accessory channel includes a distal section and a forward-viewing configuration and a side-viewing configuration. In the forward-viewing configuration, the distal section of the at least one accessory channel is substantially parallel to the distal portion of the elongate tube and in the side-viewing configuration, the distal section of the at least one accessory channel is arced at a radius greater than a radius of the distal portion of the elongate tube.

The present disclosure relates to a multifunctional visual oral cleaning instrument which includes multiple functions of a visual dental floss, and/or visual oral forceps, and/or a visual oral irrigator, and/or a visual toothbrush, and/or a detachable visual interdental brush, and the like. The dental floss, and/or oral forceps, and/or oral irrigator, and/or toothbrush, and/or interdental brush are/is connected with an oral viewer through a connecting mechanism. By using a smartphone or tablet computer, the dental floss, oral forceps, oral irrigator, toothbrush or interdental brush and the gap between teeth can be clearly seen, so that the tooth gaps can be conveniently cleaned and treated under direct vision during use, and the cleaning effect of the tooth gaps can be viewed and recorded in real time.

Certain embodiments describe an endoilluminator comprising a probe housing an optical fiber. The probe comprises a distal end with an opening through which a first light from a distal end of the optical fiber is configured to be propagated. The probe comprises one or more side openings through which a second light from one or more sides of the optical fiber is configured to be propagated. The endoilluminator also comprises a handpiece coupled to a light source and the proximal end of the probe, wherein the light source is configured to drive light into the optical fiber.

Provided is an endoscope that can appropriately illuminate an insertion direction side of an insertion part, a treatment tool and a treatment target region thereof and can reduce the diameter of a distal end part of the insertion part.

The endoscope includes a treatment tool delivery port that is formed in a distal end part body and allows a treatment tool to be delivered therethrough; an elevator that controls a delivery direction of the treatment tool delivered from the treatment tool delivery port; an observation window that is provided at a position closer to one direction side in a width direction than the treatment tool delivery port in the distal end part body in a case where a direction perpendicular to both a longitudinal axis and a normal direction of an opening surface of the treatment tool delivery port is the width direction of the treatment tool delivery port; and a first illumination window that is provided at a position closer to the other direction side opposite to the one direction side than the treatment tool delivery port in the distal end part body. A first illumination axis angle is smaller than an observation axis angle in a case where an inclination angle of an observation axis of the observation window with respect to a reference axis parallel to the longitudinal axis as seen from the width direction side is the observation axis angle and an inclination angle of a first illumination axis of the first illumination window with respect to the reference axis as seen from the width direction side is the first illumination axis angle.

A cavity illumination system according to the present disclosure may include one or more illumination elements composed of a transparent or semi-transparent, biocompatible sterilizable polymer and one or more illumination sources. The sterilizable polymer operates as a waveguide. An illumination element may incorporate micro structured optical components such as for example gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy. The micro structured optical components may also be used to polarize and/or filter the light energy entering or exiting the illumination element.

There is provided herein an endoscope assembly, the assembly comprising at least one front-pointing camera and at least one front illuminator associated therewith, at least one side-pointing camera and at least one of side illuminator associated therewith, a first front working channel configured for insertion of a medical tool and a second front working channel configured for insertion of a medical tool.

An endoscope includes a handle, an elongated body, an image sensor, a lens, a light source disposed within a distal portion of the elongated body, a processor, and a controller. The processor is disposed in electrical communication with the image sensor and the light source, and is configured to analyze at least one characteristic of a first image captured by the image sensor. The controller is disposed in electrical communication with the processor, and is configured to supply current to the light source based on the at least one characteristic of the first image analyzed by the processor.
