An endoscope (1) including a handle (2) arranged at a proximal end and an insertion tube (3) extending from said handle (2) towards a distal end, a bending section (7) arranged at the distal end and controllable by and operator via control input means (8) arranged at the handle (2); and at least one insertion tube part with at least one lumen, wherein the bending section (7) is displaceable in said lumen so as to be movable relative to the insertion tube (3) from a retracted position within said lumen to an extended position at least partially outside said lumen.

An exemplary medical system includes a first electrical circuit (204-1) on a PCB (206), a second electrical circuit (204-2) on the PCB and electrically isolated from the first electrical circuit, and a free space optics interface assembly (302) on the PCB. The free space optics assembly includes a housing (402) defining a free space chamber (404) in the housing, an optical transmitter (416) having an input (426) that is electrically coupled to the first electrical circuit, and an optical receiver (418) in optical communication with the optical transmitter via the free space chamber and having an output (432) that is electrically coupled to the second electrical circuit. The optical transmitter and the optical receiver are hermetically sealed within the housing.

An example imaging apparatus that can operate at shortwave infrared (SWIR) wavelengths are provided. An example imaging apparatus may include a fiber optic bundle, a distal lens, an illumination assembly, and an imaging detector. The fiber optic bundle may comprise a plurality of fibers and may be configured to guide light energy at a SWIR wavelength. The distal lens may be disposed on a distal end of the fiber optic bundle and the distal lens configured to focus light energy at the SWIR wavelength. The illumination assembly may be configured to output illumination at the SWIR wavelength adjacent to the distal end of the fiber optic bundle toward an object. The imaging detector may be operably coupled to a proximal end of the fiber optic bundle and configured to receive imaging light energy at the SWIR wavelength reflected from the object and guided through the fiber optic bundle.

A stereo-endoscope for observation and analysis of an object, comprising a shaft with distal and proximal ends, illuminating means for illuminating the object, and stereoscopic imaging means which transfer light radiated by the object from the distal end to the proximal end. Light of a first imaging channel is fed into a first sensor, and light of a second imaging channel is fed into a second sensor. Both sensors contain mutually different beam splitters, which split the light into four light beams. One light beam from each of the sensors is deflected onto one sensor each; these two sensors are identical. The signals detected there are assembled to form a stereoscopic image. The stereo-endoscope comprises mutually different manipulating means for the other two light beams; by means of suitably-tuned image-processing algorithms, two different monoscopic images containing information complementary to each other and to the stereoscopic image are generated.

The present disclosure relates to visualizing an operative field in the context of a dental operating theater, and more specifically, to a portable, modular, multifunctional intraoral imaging system to assist a practitioner in performing a medical or dental procedure in a confined space (e.g., intraoral cavity or mouth of a patient). The system may include an intraoral camera apparatus having a camera unit equipped with a wireless transmitter, and a viewscreen mounted to an articulated stand or dental delivery unit, wherein the camera wirelessly may transmit an image to a viewscreen located directly in front of a dental practitioner. The practitioner may look directly ahead at a high-definition screen to view the operative field. A dental practitioner may use the apparatus to perform micro-surgical procedures in a confined operative area with less-than-ideal visibility and access, without the present, though generally accepted, physical difficulties and limitations.

Provided are medical imaging apparatuses that comprising an optical connector, a coupler configured to releasably couple to a first portion of the optical connector and a camera configured to releasably couple to a second portion of the optical connector, wherein the coupler comprises a first portion to which light is incident from the optical connector, and a second portion in which the light passes through an inside of the coupler and is emitted, wherein the first portion is tilted with a predetermined angle with respect to the second portion.

A medical supporting arm according to the present disclosure includes a supporting arm and a calculation unit. The supporting arm supports an oblique-viewing endoscope. The calculation unit calculates a rotation angle of the oblique-viewing endoscope around an axis in a longitudinal direction, and an insertion amount of the oblique-viewing endoscope into a human body on the basis of a first expression that defines coordinates of a subject in a coordinate system in which an insertion opening allowing the oblique-viewing endo scope to be inserted into the human body serves as an origin, and a second expression that defines the coordinates of the subject positioned in an optical axis direction of an objective lens disposed at a distal end of the oblique-viewing endoscope in a coordinate system in which the distal end of the oblique-viewing endoscope serves as an origin.

There is provided a medical holding apparatus including: a first actuator configured to cause a medical optical tool that guides light from a body cavity of a subject to a camera head during a surgical operation, to rotate about an optical axis of the medical optical tool and a rotation mechanism configured to support the camera head that acquires an image of the body cavity of the subject via the medical optical tool, the camera head being rotatable about the optical axis of the medical optical tool independently from the medical optical tool.

There is described an apparatus comprising a first optical element, a second optical element and a spacing element for use with a mobile user device. The first optical element is configured to provide an image of an object to an intermediate image plane and the second optical element magnifies the image to provide a final image in a final image plane in which a camera aperture of the device is supported. The spacing element maintains a fixed separation between the object and the first optical element. Image magnification is achieved while also providing a space for tool access. Mirrors may be used to divert the optical path, allowing the optical path to be folded for more compact apparatus. A third optical element disposed at the intermediate image plane may be used to reduce vignetting effects in the final image.

An endoscope eyepiece grasping mechanism includes a base part engaging a tab member via a connected engagement member. An annular part has an outer engagement surface and an inner camming surface disposed coaxially with the base part and axially moveable relative to the base part. The engagement surface is moveable with the camming surface to move the tab member radially outwardly, with a movement of the annular part relative to the base part in a first axial direction, toward a receiving position, and to move the tab member radially inwardly, with movement of the annular part relative to the base part in a second axial direction, toward a grasping position. A biasing device acts to bias the annular part toward the grasping position. An endoscope eyepiece is engaged by the tab member upon the annular part moving from the receiving position to the grasping position.
