Endoscope tube system
First Claim
1. An endoscope tube system, comprising:
- an elastically bendable tube section including individual members spaced behind one another in an axial direction of said tube system;
an axially extending stabilizing spring band, each of said individual members being fixed on said stabilizing spring band at a circumferential area thereof;
an axially extending tension spring band arranged opposite said stabilizing spring band and being axially movable relative thereto, a most axially forward of said individual members being fixed to said tension spring band;
wherein at least one of said stabilizing spring band and said tension spring band has a curvature in a relaxed condition; and
wherein the elastically bendable section is bendable in a direction opposite to said curvature through axial movement of said tension spring band.

Abstract
In an endoscope tube system, an elastically bendable section is constructed of individual members spaced with respect to one another. A stabilizing spring band and a tension spring band are provided. The spring bands extend in a mutually opposite manner axially along the circumferential area of the individual members and at least one of the bands have a natural curvature which is opposite to the bending direction of the bendable section. The individual members are fixed on the stabilizing spring band, while the tension spring band is only connected with the most forward individual member. This construction of the bendable section requires no tension cables and is therefore operationally reliable, easy to take apart, and easy to clean.

6. An endoscope tube system, comprising:
-
an elastically bendable tube section including individual members spaced behind one another in an axial direction of said tube system; an axially extending stabilizing spring band on which at least a most rearward one and a most forward one of said individual members are fixed on said stabilizing spring band at a circumferential area thereof; an axially extending tension spring band arranged opposite said stabilizing spring band and being axially movable relative thereto, a most axially forward of said individual members being fixed to said tension spring band; wherein at least one of said stabilizing spring band and said tension spring band has a curvature in a relaxed condition; and wherein the elastically bendable section is bendable in a direction opposite to said curvature through axial movement of said tension spring band.
