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.

A visualization system, an apparatus, and a visualization method are provided. The visualization system includes a laparoscope, a camera operatively coupled to the laparoscope, a light source operatively coupled to an illumination port of the laparoscope, and processing circuitry. The light source is configured to output one or more light beams each at a predetermined frequency to illuminate a target area. The processing circuitry is configured to process imaging data from the laparoscope received by the camera to generate one or more images of the target area including at least one laser speckle contrast image. The laparoscope is configured to output the one or more light beams toward the target area at a distal end thereof and to collect reflected and/or scattered light from the target area via the distal end.

There is provided a lens for use in a human or animal body, the lens comprising a metasurface configured to modulate incident light, wherein the metasurface is composed of at least one light transmissive biomaterial. Also provided is a method of making the lens.

The present disclosure relates to a cap for protecting an imaging instrument from damage caused by impact or poor handling. Exemplary devices can include a rigid outer shell and soft inner lining surrounding a distal tip of the instrument, to be applied between instrument use, and during instrument transport, disinfection, sterilization, and storage.

A disposable cover for use with an endoscope includes an elongated sheath having and having an open proximal end and a closed distal end. A channel extends along a central axis of the sheath from the open proximal end to the closed distal end, and the channel is configured to accommodate insertion of an endoscope. A proximal region of the sheath is formed as a rigid thin-wall sleeve and a distal region of the sheath is formed as a flexible thin-wall sleeve. The flexible thin-wall sleeve is configured to allow deflection of said distal region in cooperation with an articulating distal end of an endoscope.

An endoscope includes a shaft having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft, and an image sensor is carried on the distal end of the shaft. A channel extends through at least a distal shaft portion and has a channel diameter, and a section of the channel is re-configurable between a constricted shape and a non-constricted shape to accommodate tools introduced therethrough. The combined diagonal dimension and channel diameter is usually greater than the outer shaft diameter. The image sensor may be connected to a connector on the housing by a first slack flex circuit and a lights source on the shaft may be connected to a connector on the housing by a second slack flex circuit.

A wide-angle optical system includes a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third lens unit having a positive refractive power. At the time of carrying out a focal-position adjustment, the second lens unit is moved. The third lens unit includes a positive single lens on an image side of a cemented surface Sc having a negative refractive power nearest to an image in the third lens unit, and has a plurality of refractive surfaces having a negative refractive power on the object side of the cemented surface Sc. The third lens unit has at least one refractive surface Sp having a positive refractive power which satisfies following conditional expression (1):

0.02<fL/Rsp<1.20  (1).

A video imaging system is provided. The video imaging system is configured to maintain a video image displayed on a display unit in a predetermined orientation based upon a use. The video imaging system includes an endoscope, a camera head unit, a camera control unit configured to determine a focal distance, and a display control unit. The display control unit is configured to process the focal distance to determine a use. The use is processed by the display control unit so as to maintain the video image in the predetermined orientation. The contextual information may be focal distance, image data or endoscopic orientation.

An endoscope including an elongated insertion section; a side observation window that includes a tapered part on a side circumference intersecting in a longitudinal axis direction of the insertion section, a circumferential side surface formed in a cone shape; and a cleaning nozzle that includes an opening through which liquid cleaning the circumferential side surface of the side observation window is ejected. The opening is inclined to direct an ejection direction of the liquid toward a distal end of the tapered part. A center position of the opening part of the cleaning nozzle is provided on a proximal end side with respect to a center position of the side observation window in the longitudinal axis direction.
