Instrument zum Einfuehren in unzugaengliche Raeume

(A1) Es wird ein Instrument zum Einfuehren in von aussen unzugaengliche Raeume mit einem Einfuehrabschnitt und einem mit diesem verbundenen flexiblen Endabschnitt, der mit Druckkammern versehen ist, vorgeschlagen, wobei ueber eine Druckbeaufschlagung der Kammern eine Biegung des flexiblen Endabschnitts hervorgerufen wird, bei der der flexible Endabschnitt eine in Form eines Faltenbalgs ausgebildete Aussenhuelle aufweist.

WO 2009100954 A1 UPAB: 20090902 NOVELTY - The instrument (1) has an insertion portion (3), and a flexible end portion (4) connected to the insertion portion, where the flexible end portion is provided with pressure compartments (5). The flexible end portion is bent when pressure is applied to the compartments, where the flexible end portion comprises an outer case in the form of bellows. An inner tube (17) is arranged coaxial to the outer case of the flexible end portion, and is connected with the outer case via longitudinal webs. The compartments are formed among the outer case, the inner tube, and the longitudinal webs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for producing an end portion for application in an invasive instrument. USE - Invasive instrument i.e. endoscope, for insertion into body spaces e.g. gas-filled spaces such as lung and abdomen, and fluid-filled spaces such as blood vessel and joint, that are inaccessible from the exterior, for diagnosis and treatment of the body spaces, in a hospital and a clinic. Can also be used for inspecting a turbine blade-hollow space and for removal of burr in a borehole of the hollow space. ADVANTAGE - The inner tube is arranged coaxial to the outer case of the flexible end portion, and is connected with the outer case via longitudinal webs, and the compartments are formed among the outer case, the inner tube, and the longitudinal webs, such that the instrument is applicable in versatile application areas, and is designed to have small geometric in a cost-effective manner, while achieving good controllability of the locomotion and change of direction of movable end portion.
