Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung eines Einführschlauches (2) eines Endoskops aus einem Rohrelement, wobei der Einführschlauch (2) einen proximalen passiven flexiblen Abschnitt (C) und einen distalen Abwinkelungsabschnitt (A) aufweist, wobei im proximalen passiven flexiblen Abschnitt (C) Schnitte (98, 99; 990, 991) vorgesehen werden, um ein Biegen des proximalen passiven flexiblen Abschnittes (C) zu ermöglichen. In diesem Verfahren werden die Schnitte (98, 99; 990, 991) im proximalen passiven flexiblen Abschnitt (C) so ausgebildet, dass benachbarte Schnitte (98, 99; 990, 991) ungleich beabstandet sind. Die Erfindung betrifft außerdem ein Endoskop mit einem solchen Einführschlauch.
(EN)
The invention relates to a method for producing an insertion tub (2) of an endoscope from a tube element, wherein the insertion tube (2) has a proximal, passive, flexible section (C) and a distal, anglable section (A), wherein cuts (98, 99; 990, 991) are made in the proximal, passive, flexible section (C) in order to permit a bending of the proximal, passive, flexible section (C). In this method, the cuts (98, 99; 990, 991) in the proximal, passive, flexible section (C) are designed such that neighbouring cuts (98, 99; 990, 991) are unevenly spaced apart. The invention also relates to an endoscope having an insertion tube of this type.
(FR)
L’invention concerne un procédé de fabrication d'une gaine d'introduction (2) d'un endoscope à partir d'un élément tubulaire, la gaine d'introduction (2) présentant une partie souple passive proximale (C) et une partie coudée distale (A), des découpes (98, 99; 990, 991) étant pratiquées dans la partie souple passive proximale (C) pour permettre une flexion de la partie souple passive proximale (C). Dans ce procédé, les découpes (98, 99; 990, 991) pratiquées dans la partie souple passive proximale (C) sont formées de telle sorte que des découpes (98, 99; 990, 991) adjacentes présentent des espacements inégaux. L'invention concerne également un endoscope équipé d'une telle gain d’introduction.
