An endoscope is provided, with a main body and a rigid shaft, extending from the main body, which has a first section which extends in a rectilinear manner, a curved second section adjoining it and a third section, adjoining the second section, which forms a distal end of the shaft. The shaft includes, for receiving an instrument, a one-piece instrument tube which extends to the distal end of the shaft and has an open end there, and an optics module by means of which an image of an area in front of the distal end of the shaft can be recorded. A cladding tube extending from the main body to the distal end is provided, in which the instrument tube and the optics module are arranged, and which includes a rectilinear part for the first section and a curved part, connected to the rectilinear part, for the second section.

Endoscope with a rigid curved shaft as well as process for producing such an endoscope

An endoscope is provided with an endoscope shaft and a main body connected to the endoscope shaft. The endoscope includes a camera connection to which an optical recording device can be mechanically fixed. The main body is electrically conductive. The camera connection includes an electric insulating body that electrically insulates an optical recording device, mechanically fixed to the camera connection, from the main body.

Endoscope

A trocar device includes a main part that has a first and a second end. A shaft tube is connected to the second end of the main part. A through-opening for receiving an instrument extends from the first end of the main part to the end of the shaft tube that faces away from the main part. A sealing unit is disposed in the main part and has an elastic sealing element having a hollow-cylindrical wall, which divides the through-opening into a first region that runs from the sealing unit as far as the first end of the main body, and into a second region that runs from the sealing unit as far as the end of the shaft tube that faces away from the main part. When the instrument has been properly inserted in the through-opening, the sealing element seals off the two regions from each other.

Trocar device

An endoscope includes a handle and a shaft connected thereto. Imaging optics are arranged in the shaft that image an object located in the direction of view of the imaging optics in front of the shaft as an image and which to set the desired direction of view. The imaging optics comprise a swivellably housed deflecting unit positioned at the distal end of the shaft facing away from the handle. The possible swivel range of the imaging optics has a first and a second limit, as well as an actuating element, which is attached to the handle and which is mechanically connected to the deflecting unit. Thereby the swivel position of the deflecting unit within the swivel range can be changed in order to set a desired direction of view. A first mechanical stop is provided against which the deflecting unit lies when the first limit is reached.

Endoscope with variable direction of view

Provided is an endoscope with a handle and an endoscope shaft connected to the handle, which has a bendable section and a rigid section, adjoining it, with a support extending in the longitudinal direction of the endoscope shaft, wherein the bendable section has a flexible outer tube the end of which facing the rigid section rests on the support, wherein a fixing sleeve is connected to the end section and covers the end of the outer tube facing the rigid section such that said end is clamped for fixing between the fixing sleeve and the support.

An endoscope is provided, comprising a first tube whose distal end is sealed with a cover glass disposed in a mount and an electric heating system for heating the cover glass, with the heating system comprising two electric connections which can be connected with a power source, and an electrically conductive coating which is applied to the inside of the cover glass and comprises two mutually spaced contact sections, of which one each is electrically connected with one of the connections, and with the mount being electrically conductive and a first of the two contact sections being electrically connected via the mount with the associated connection.

Endoscope with an electric heating system

A shutter for use as an objective for improving the depth of focus in a camera is disclosed. The shutter has, in a central area, a radially uniform transmission function averaged over the circumferential angle. The radial transmission function first drops off toward zero in a radial transition area which is a continuation of the central area and which has a quantity n of cutouts which extend toward the radial outside and are spaced apart from one another at equal angles 360&deg;/n in the circumferential direction. The quantity n of cutouts has the value 5, 6 or 7.

Shutter, in particular for an objective, and a CCD-camera

An endoscope with a coupling device for the connection of a video camera, wherein the endoscope has, at its needle-shaped tube, a distal end which is provided for insertion into the body and a lens system and has a proximal end provided for looking into the endoscope and having a field diaphragm, the coupling device being attached to the proximal end, and wherein a lens system is arranged following the field diaphragm and, like the lens system at the distal end, is sealed off from the outside completely and tightly and is constructed so as to be non-adjustable and non-focusable. The coupling device has no lenses and is adjustable with respect to its axial length in the manner of a telescope.

Endoscope with a coupling device (video coupler) for connection of a video camera

An electronic endoscope with a semiconductor image sensor (CCD chip) for receiving the images received by an objective and with an The electronic circuit, wherein the endoscope substantially comprises a shaft with a distal end and a proximal end, and the objective and CCD chip are arranged at the distal end, and the proximal end is held in a housing which holds the shaft and encloses the glass-fiber optical connection. The electronic endoscope is wherein the component parts of the CCD chip unit arranged behind the objective, namely the crystal filter, IR cutoff filter and CCD chip, are arranged so as to be spaced from one another.
