A medical device comprising an endoscope accessory for attachment to the working end of an endoscope. The coupler device provides a flexible working channel extension from the endoscope so that instruments can exit the endoscope at various angles. The device also provides a protective cover to reduce the ingress of debris, fluid, bacteria, or other unwanted matter from the working end of the endoscope which could lead to infection.

An endoscope and methods of use thereof is provided with at least one multi-functional, multi-directional arm supporting a plurality of imaging, lighting and other sensory elements. The multi-functional arms provide a mounting platform upon which cameras, lights and sensors may be mounted to generate multiple-angled images and video, arena-like lighting and other data relevant to performing a diagnostic or MIS procedure. The multi-directional arms may be inserted through a single portal in the endoscope and deployed in multiple directions from a single portal once inserted into a body cavity. The pitch, roll, length and curvature of each of the extending arms may be individually or jointly adjusted to create a customized view of an internal space during an endoscopic procedure. The extending arms may also include communication elements to wirelessly transmit the images and other data generated by the sensory elements to a remote computing and display device.

In an endoscope (1), two optical paths (3, 4) for stereoscopic vision are formed, wherein each optical path (3, 4) is lead from the inside to an interface (16, 19) with an optically more dense material (14) in relation to the surroundings (13) at a point of incidence (22, 25), wherein each optical path (3, 4) can be opened and interrupted by modifying the reflection behavior at the respective point of incidence (22, 25).

An articulated device may include a first steerable multi-linked mechanism and a second steerable multi-linked mechanism. The second steerable multi-linked mechanism may include a first link, a plurality of intermediate links and a second link movably coupled to a second one of the intermediate links. A first one of the intermediate links may be movably coupled to the first link. The articulated device may include a camera located within at least a portion of the second link and a protective shield connected to a distal end of the second link. The protective shield may surround at least a portion of the camera.

The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

An object of the invention is to provide an endoscope capable of continuously grasping a direction which a distal end portion of an endoscope faces even when a bending operation is performed. The endoscope of the invention is provided with: a first image pickup optical system provided at a distal end of an insertion portion; a bending portion provided in a vicinity of a distal end portion of the insertion portion and configured to be bendingly operated by a proximal side operation; and a second image pickup optical system disposed on the bending portion and configured so that the distal end of the insertion portion is included within a field-of-view angle.

A circuit board design uses CMOS sensors for the tip section of a multi-viewing element endoscope. Side sensors and their optical assemblies are assembled to a common base board to save space. Individual base boards are separately constructed, inserted into grooves of a main base board, and are further connected to the main base board by means of flexibal circuit boards.

An endoscope includes: an insertion portion; a first observation portion configured to observe a first area including a front of the insertion portion; a second observation portion configured to observe a second area including a side of the insertion portion and be adjacent to the first area; a first illumination portion configured to irradiate the second area with first illumination light; and a second illumination portion configured to irradiate the second area with second illumination light, and the second illumination portion performs irradiation with the second illumination light of a light quantity equal to a light quantity for which the first illumination light in a range observed in the second observation portion and illumination light from an illumination portion configured to irradiate the first area with the illumination light are put together.

Devices and methods for treating rhinitis are provided. An integrated therapy and imaging device is provided for single handheld use. The device may have a hollow elongated cannula, a therapeutic element coupled to a distal portion of the cannula, an imaging assembly coupled to the cannula to provide visualization of the therapeutic element, and an articulating region operably coupled to the imaging assembly to articulate the imaging assembly. The imaging assembly may be articulated so as to translate vertically, laterally, axially, and/or rotationally.

An endoscope handpiece and system may include an angle of view selector, a depressible button, which may be connected to a lock disposed within a port of the endoscopic handpiece. The system may further provide an endoscope, which may be connected to the handpiece via the port and locked in place by the lock.
