Abstract: An endoscopic system according to the invention, in particular for colonoscopy, includes a flexible endoscope with an elongate, flexible shaft, a regulator part, and also an operating part which can be placed on or pushed onto the shaft and which has at least one control element, wherein the endoscopic system furthermore includes a shaft stop, which can be secured on a patient support and which has a locking mechanism, controllable by the at least one control element, for locking the shaft against movement in a longitudinal direction of the shaft.

Abstract: A flexible endoscope shaft with a shaft body which, viewed in the longitudinal direction of the endoscope shaft, is composed of at least two shaft portions with different degrees of flexibility, wherein at least one shaft portion is composed of at least one spring element, and wherein all the spring elements of the shaft portions, which, viewed in the longitudinal direction of the shaft body, are arranged proximally from the outer distal shaft portion, are designed as reversibly deformable spring rods extending in the longitudinal direction of the shaft body. In order to create a flexible endoscope shaft that can be produced easily and cost-effectively, each of the shaft portions having at least one spring rod has at least one further spring rod, which is integrally bonded to the other spring rods of the respective shaft portion.

Abstract: The invention relates to an endoscope having a bendable guide element, by means of which a tool can be securely guided and simultaneously steered outward into a broad operating area at the head of the endoscope.

Abstract: The invention relates to an endoscope having a shaft in which at least one working channel is positioned and having on the distal end of the shaft an endoscope head, such that the part of the working channel contained in the endoscope head can be rotated with respect to the related working channel by a Bowden cable that is mounted on a control handle on the proximal end by a collet. To configure an endoscope in such a manner that it ensures simple construction as well as a constantly even tension of the Bowden cable, it is proposed with the invention that the depth of insertion of a cable cord of the Bowden cable into the collet can be limited by a pressure element acting on the cable cord and collet.

Abstract: The invention relates to an endoscope comprising a first quick-acting closure (3) for a traction wire (13) of a Bowden wire device, which closure is arranged at the proximal end to be pivotable or displaceable, with a locking position of the quick-acting closure (3), in which an attachment unit for loosening and attaching the traction wire (13) of the Bowden wire device can be actuated and with a working position of the quick-acting closure (3), in which the attached traction wire of the Bowden wire device can be displaced within a working area which is defined by end positions (15′, 15″) of the quick-acting closure (3), in order to actuate a mechanism which is arranged at the distal end of the endoscope together with the traction wire (13) of the Bowden wire device in such a way that it can be loosened.

Abstract: The subject matter of this invention concerns an endoscope, in particular a flexible endoscope, with a minimum of one valve which is positioned at the proximal end of an endoscope housing and which comprises a valve piston and a valve cylinder with a plurality of valve openings, with the minimum of one valve provided being designed as a valve module which is detachably connected to a complementary recess in the endoscope housing.
