A method for intraoral scanning, including introducing an intraoral scanner (IOS) head into an oral cavity, acquiring an image of a field of view (FOV), processing the acquired FOV image and adjusting at least one image acquisition parameter based on said processing, and an intraoral scanner (IOS) including an IOS head including at least one imager imaging a field of view (FOV), at least on light emitter that illuminates said FOV and circuitry that controls said imager and/or said light emitter.

The present invention relates to an ultra-small endoscope camera module comprising: a first tube body having one or more object lenses; and a second tube body supporting the first tube body from one side, wherein an image capturing means, which is adjacent to the rear of the object lenses, is provided on the inner side of the second tube body. Moreover, the present invention relates to an ultra-small endoscope camera module comprising: a body tube having an accommodation space for fixing and supporting one or more object lenses; a front tube covering the outside of the body tube; an image capturing means disposed on the rear end of the body tube; and a main tube covering the outside of the image capturing means, wherein the outside diameter of the front tube is greater than the outside diameter of the main tube. Moreover, the present invention relates to an ultra-small endoscope characterized by the aforementioned ultra-small endoscope camera module being disposed on the front end of a scope. Accordingly, the image capturing means for obtaining an image is disposed on the front end of the scope and thus a high-quality image can be obtained.

An endoscope includes: an objective optical unit; an illumination optical system including an illumination lens; and a distal end portion body included in a distal end portion, and the objective lens barrel includes a first lens barrel and a second lens barrel, the first lens barrel includes a disposition hole, an inward projection portion and an outward projection portion, the second lens barrel includes a reception hole, a light input surface and a first distal end face are arranged in a same plane by a beveled surface of a beveled portion being in surface contact with a lens positioning surface of the inward projection portion, and the first distal end face and a second distal end face are arranged in a same plane by a first barrel positioning surface being in surface contact with an objective optical unit positioning surface.

Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and resuable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.

An endoscope includes a first flat surface formed at a distal end portion of an insertion part to be inserted into a subject, and orthogonal to an axial direction of the insertion part, an observation window provided at the distal end portion for allowing image light of the subject to be taken therethrough, with a surface of the observation window as a light incidence plane, a forceps outlet disposed on the first flat surface, a first illumination window provided at the distal end portion to irradiate a subject with illumination light, a second illumination window provided at the distal end portion to irradiate the subject with illumination light, a fluid jetting nozzle arranged at the first flat surface to jet a fluid toward the observation window and fixed at the distal end portion of the insertion part, and an inclined surface formed around the observation window.

The invention provides an imaging system comprising an optical element for deflecting axially incident light into a series of axially spaced outward radial projections, and further comprising an image collection means for collecting reflected light. The element comprises a plurality of light deflecting surfaces or features which are arranged at axially successive points along the element, each at a different radial location. The light-deflecting surfaces are arranged to deflect light incident upon them from an axial direction in a radial direction, each thereby generating a radial projection of light from the element. A beam or beam bundle projected along the element has successive outer annular layers stripped by the facets and deflected outwards at different axial points along the structure.

An endoscope assembly comprising a handle incorporating a liquid reservoir and injection system, a flexible or rigid cannula attaching to the handle, and a distally attached miniature imaging head. The imaging head is a transparent tubular shaped body having an essentially closed proximal end, and a tubular wall extending from the closed proximal end to the distal open end of the body. An optical source is attached to the closed proximal end, and its emitted illumination directed into the tubular wall of the body, such that said illumination is internally reflected within the tubular walls and is emitted from the distal open end. A detector array is disposed within the inner surfaces of the tubular wall section, and a lens images light reflected back into said imaging head, onto the detector array. The optical source is disposed radially inwards of the outer dimensions of the tubular shaped body.

A light transmitting probe for use in endodontic procedures comprises a light transmitting core and a metallic sheath surrounding said core. The metallic sheath defines a reflective inner surface. The probe further includes a plurality of apertures formed in the sheath, such that light can exit said probe through the apertures.

An introducer/exchanger for a tracheostomy device includes a flexible elongate member having a proximal end, a rounded blunt distal end, and a lumen extending from a proximal opening at the proximal end to a distal opening at the distal end. A distally pointing light is mounted to the rounded blunt distal end. A power source is provided for the light.

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.
