1. An insertion aid for medical instruments, comprising:
- a shaft having a proximal end, a distal end, and a bending part having structures which allow a bending in at least one desired direction different from an extension direction of the shaft; and
a tension element for actuating the bending part;
wherein the shaft further comprises an outer tube element and an inner tube element supported in the outer tube element so as to be axially movable, wherein the tension element is hinged to one of the inner and outer tube elements and the bending part is provided at a distal end of the other of the inner and outer tube elements.

Abstract
An insertion aid for medical instruments includes a shaft having a proximal end, a distal end, and a bending part, and a tension element for actuating the bending part. The bending part includes structures which allow a bending in at least one desired direction different from an extension direction of the shaft. The shaft further comprises an outer tube element and an inner tube element supported in the outer tube element so as to be axially movable. The tension element is hinged to one of the inner and outer tube elements and the bending part is provided at a distal end of the other of the inner and outer tube elements.
