摘要:
An apparatus for testing the state of the optical system of an endoscope comprises a first supporting device for the endoscope, a test pattern and a second supporting device for the test pattern, wherein the test pattern comprises a pattern, which allows a check of the actual viewing direction and of the actual field of view angle within tolerance values.

An endoscope has a tubular shaft whose interior contains components, in particular lenses, spacers, diaphragms, prisms and filters of an optical system, said components being at least partially surrounded by a support piece made of shrunk material. It is proposed that the components be surrounded by a transparent and tube-sleeve-shaped shrunk material which has been shrunk before the components are introduced into the tubular shaft.

A laryngoscope includes a handle, a spatula arranged substantially transverse to the handle, and a coupling detachably fixing the spatula to the handle. An illumination light waveguide guides an illumination light signal and an image waveguide guides an image signal, both waveguides being attached to the spatula. The illumination light waveguide includes a proximal end having an illumination light entry opening, and the image waveguide includes a proximal end having an image exit opening, wherein the illumination light entry opening and the image exit opening are arranged in the area of the coupling. The handle includes, in the area of the coupling, an illumination light exit opening and an image entry opening which allow for the illumination light signal to couple into the illumination light waveguide from the handle, and for the image signal to couple out of the image waveguide. A centering element automatically aligns the image entry opening and the image exit opening precisely to each other.

An endoscope, in particular a video endoscope, has an endoscope shaft at the distal end and a mount at the proximal end for attaching an optical imaging device, for example a video camera, and an endoscope housing between said endoscope shaft and said mount, said mount being rotatable relative to said endoscope shaft, via a rotary joint, about the longitudinal axis of said endoscope an optically imaging arrangement, which is at least partially positionally displaceable by way of an adjusting device for focusing the image transmission, moreover being received in said endoscope housing. Said endoscope housing is configured in continuously hermetically sealed fashion, and said rotary joint is arranged outside said endoscope housing.

A method for mounting at least one rod lens in an interior of a tube has the following steps, i.e. selecting an outside diameter of said rod lens in that an airgap is created circumferentially between an outer side of said rod lens in an inner side of said tube, positioning said outer side of said rod lens at a defined radial spacing from said inner side of said tube by way of at least two centering aids and effecting an elastic adhesive join between said outer side of said rod lens and said inner side of said tube.

Distance holder for lenses, which in terms of shape or material structure is configured in such a way that it exerts a slight notching effect on lenses on contact surfaces between a distance holder and a lens, so that the lens surface is less easily damaged.

A device for positioning components within endoscopic systems includes a hermetically sealed housing. An outer ring element is mounted to rotate about the outer side of the housing and carries on its circumference at least one outer magnet. Further, an inner ring element is mounted inside the housing and carries likewise at least one inner magnet, the magnets being aligned in such a way that any rotation of the outer ring element has the effect to move the at least one inner magnet by magnetic coupling, such movement serving the purpose to position the respective components. In order to achieve a simple, relatively small and functionally safe structure it is proposed that both the outer and inner ring elements be configured as axially displaceable rings carrying the oppositely arranged magnets, and that the inner ring be mechanically connected with the component to be positioned.
摘要:
An endoscope comprising at least one sensing and recording device disposed in the interior of the endoscope, which detects at least one ambient parameter such as temperature, pressure, humidity, irradiation, other ambient conditions and/or shock or impact loads which the endoscope is exposed to, where the information recorded by the sensing and recording device may be extracted from the outside or transmitted to the outside of the endoscope without disassembly of the endoscope.

A coupling provides mechanical, light-guiding, and image-guiding connection of an endoscope to a camera module. It is proposed that a first cylindrical stem, in whose interior a proximal end segment of the light guiding system is received, project in the coupling direction from a coupling end of the endoscope. Also projecting from the coupling end in the coupling direction is a second approximately cylindrical stem whose length and diameter are greater than the length and diameter of the first stem, a proximal end segment of the image guiding system being received in the interior of the second stem. The second stem coacts with an interlock arranged on the camera module, for mechanical interlocking of the coupling. The first and second stems extend at a distance next to one another, and the coupling end of the camera module has receptacles, complementary to the two stems, into which the two stems penetrate. In the base, the receptacle into which the second stem enters is optically connected to the image sensing system of the camera module, and the receptacle into which the shorter first stem can be received has a light guide.
摘要:
An endoscope has an outer shaft, in which an optical channel receiving an optical system is arranged, wherein in the outer shaft, further, a channel for receiving a working element, at least one supply channel extending longitudinally for a medium and at least one discharge channel extending longitudinally for the discharge of a medium, the discharge being separated from the supply, are arranged. The optical channel and the at least one supply channel and/or the at least one discharge channel are configured as chambers of a profiled shaft, which is chambered in its cross section and received in the outer shaft.
