A medical endoscope including: an elongated shaft with a distal end region having a non-circular cross-section and a shaft main section arranged proximally from the distal end region, an at least one light guide having a plurality of individual fibres disposed longitudinally through the shaft, wherein at least a portion of the plurality of individual fibres in the distal end region are bonded over a length of at least 50% of the distal end region with an inflexible adhesive.

Endoscope with bonded light guide

A rigid endoscope including: a shaft; a body disposed at a proximal end of the shaft, a fiber image guide mounted to move longitudinally within the shaft and body; a securing section for securing the fiber image guide, the securing section being positioned within the body; a sliding element mounted to move longitudinally within the body; and a protective sheath encasing the fiber image guide; wherein the fiber image guide is twisted, for image rotation, in a longitudinal portion corresponding to the protective sheath.

Rigid endoscope

A surgical instrument including: a main body; an elongated shaft tube connected to the main body, the shaft tube having at least one working channel tube arranged in an interior of the shaft tube, the at least one working channel tube extending in a longitudinal direction of the shaft tube; and a connection body coupled to a proximal end region of the main body; wherein a proximal end region of the at least one working channel tube is accommodated inside the connection body and is sealed with respect to the connection body.

Surgical instrument and method for producing a surgical instrument

A surgical instrument, such as an ureteroscope. The surgical instrument including an elongated shaft tube with at least two working channels arranged in an interior of the shaft tube. In at least a distal end area of the shaft tube, the at least two working channels, in cross-section, each have a profile edge.

Surgical instrument having working channels, each having a profile edge

An eyepiece device for a surgical instrument, the eyepiece device including: an eyepiece frame; and at least one optical unit accommodated in the eyepiece frame, wherein the at least one optical unit comprises at least one first optical element and a second optical element connected with the at least one first optical element, wherein the second optical element is formed from a second material with abnormal dispersion and the first and the second optical elements together correct chromatic aberration; wherein the eyepiece frame comprises an expansion chamber for at least the second optical element, the expansion chamber forming an installation space for at least the second optical element in a radial direction.

Eyepiece device for a surgical instrument

An ocular device for a surgical instrument having an ocular mount for an optical assembly. The ocular device including: an optical flat; and a holder for accommodating the optical flat, wherein the holder is configured to be connected to the ocular mount; wherein the optical flat having a widened side edge provided with a first contact surface for the ocular mount and a second contact surface for the holder, and a surface normal of the optical flat and the first contact surface of the optical flat facing the ocular mount form an angle different than 0&#xb0; relative to each other.

Ocular for a surgical instrument

An ocular device for a surgical instrument, the surgical instrument having an optical window frame and an optical assembly arranged in an interior space of the surgical instrument, the ocular device including: an ocular window separated from the optical assembly by a space; a holder configured to be connected to the ocular window frame; and at least one elastic element, wherein in a connected state, the at least one elastic element transmits a clamping force from the holder to bias the ocular window towards the space.

Ocular device and surgical instrument having an ocular device

An endoscopic optical system including: a fiber image conductor arranged in an elongated shaft tube, the fiber image conductor having a proximal face; an objective arranged distally relative to the fiber image conductor; an observation device arranged proximally relative to the proximal face of the fiber image conductor; a mask; and a transparent cover pane arranged between the proximal face of the fiber image conductor and the observation device; wherein the transparent cover pane is configured as a moire filter.

Endoscopic optical system

A rigid endoscope including: a fiber tube; a window disposed at a the distal end of the fiber tube; an objective lens arranged in the fiber tube; a spacer tube to maintain the objective lens at a predetermined-distance from the window; and an objective lens tube for holding the objective lens, the objective lens tube being disposed in the fiber tube between the window and at least a portion of the spacer tube; wherein the spacer tube is supported on a distal end against the window and on a proximal end against the objective lens.

A system tube of an endoscope optical system, designed to contain cylindrical elements of an image guide provided with lenses and to support the elements by tongues cut out of the wall of the system tube and deformed nonelastically. Wherein the tongues are deformed toward the outside and are bent elastically by a holder toward the inside to below the level of the outer surface of the system tube.
