Demonstration approach for endoscopes

The innovation relates to a demonstration approach for endoscopes for the monitoring of one of the endoscope optics captured image, its rays by means of a partially transparent prism assigned to the eyepiece are divided.

In the known demonstration approaches for endoscopes, one goes from an attachment to the endoscope eyepiece rigid branch off to the side, which is part of the from the endoscope optics captured image via a partially transparent Prism transfers to a arranged at the end of the junction secondary eyepiece. This well-known demonstration approach has the major disadvantage that when the endoscope changes position, the person examining it The doctor and the co-observer have to make the necessary rotations in order to correctly evaluate the captured image to be able to.

It has therefore already been suggested for the demonstration approach a flexible fiber image conductor to use, which brings an improvement over the rigid connection with it. on the other hand Considerable disadvantages have to be accepted by the fiber image guide. One of those drawbacks is that flexible fiber image guide the captured image only in significantly reduced image quality forward in terms of resolving power, and Another disadvantage arises from the fact that the field of view of the other observer is opposite to the field of view of the endoscope tube is severely limited because the glass fibers used for the fiber image filter are only allow a limited angle of incidence of the image rays.

A very significant further disadvantage of all known designs is that the observation port must also contain an optical system for the examining doctor, the. From the periscope captured image, changed why the examiner Doctor when using such demonstration approaches from the familiar image again and again to a changed one Picture must adjust. This primarily affects the safety of operations to be carried out.

With the new demonstration approach, the disadvantages the known demonstration approaches are avoided, so that the co-observer can see the image in the Body cavity can see in every detail exactly as the examining doctor and that the visual

/ field of the observer is not smaller than that

Field of view of the endoscope tube * This is achieved by the fact that the approach consists of a known, consists of a flexible cover, short focal length lens system that is attached to the Endoscopic eyepiece attachable and the partially transparent prism enclosing head piece goes out laterally and with a secondary associated with the lens system

Endoscopic eyepiece is designed to complement the eyepiece and have a direct view of the partially transparent prism are.

The somewhat limited flexibility of the sheath enclosing / enclosing the lens system compared to a flexible fiber image conductor is not disadvantageous because that

Head piece is arranged freely rotatably on the endoscope eyepiece according to a further feature of the innovation. The endoscope can therefore be rotated about its longitudinal axis without the flexible observation connector having to take part in the rotary movement.

The Neuertang also offers the advantage over the known demonstration approaches that a special Observation port for the examining doctor is dispensable. The examining doctor always has the same and familiar image in front of him does not matter whether he works with or without a demonstration approach. He looks through a central opening on the headpiece of the demonstration approach directly through the partially transparent prism into the endoscope tube. By eliminating the observation socket with its optical system is essential for the examining doctor Achieved brightness gain.

Another improvement on the demonstration approach was achieved in that the flexible approach with a connection for a so-called hanging cable or is provided for a hanging device. With this connection, the flexible attachment retains its hanging position even if the endoscope has to be rotated about its longitudinal axis. Hanging cable and flexible approach act together as a suspension device for the endoscope,

In the drawing, the new demonstration approach for endoscopes is illustrated using an exemplary embodiment, which shows this in a partial longitudinal section, with the associated endoscope in outline is indicated.
