Patent ID: 8327518

Claim:
A method for manufacturing a bendable tube for an endoscopic instrument, the method comprising separating a tube ( 2 , 2 ′) into several tube sections ( 4 , 4 ′) in a manner such that adjacent tube sections ( 4 , 4 ′) engage into one another with a positive fit in an axis direction of the tube ( 2 , 2 ′), and arranging means for forming a positive fit transverse to the axis direction of the tube ( 2 , 2 ′) peripherally at regions of the tube sections ( 4 , 4 ′), the regions being situated in engagement with one another, wherein the means for forming the positive fit transverse to the axis direction of the tube ( 2 , 2 ′) comprises an enveloping tube ( 12 ) which is arranged around the tube ( 2 , 2 ′), wherein the enveloping tube ( 12 ) is separated into tube sections, wherein separating gaps are formed between the tube sections of the enveloping tube ( 12 ), in such a manner that the tube sections remain connected to one another via at least one web ( 18 ), and wherein the enveloping tube ( 12 , 12 ′) is welded at least one web end to the bendable tube ( 2 , 2 ′) arranged therein.
