## Abstract

A hand-operated functional hose instrument has a hose-like functional part and a wire-like functional part which extends in the hose-like functional part. An operating unit, which is designed for releasable coupling to an operator control handle body, is arranged at a proximal end section of the functional parts and includes two operating parts, which are axially relatively movable and have a hose fixing arrangement or a wire fixing arrangement. The first operating part is axially fixed to the operator control handle body, and the second operating part has a finger-operated operator control slide element. The first operating part has a finger-operated operator control rotary element and/or a distal cone section with an axial recess into which the second operating part can be at least partially inserted, and/or the wire fixing arrangement has two wire fixing parts which can be rotated in relation to one another about a longitudinal axis from a wire release position to a wire clamping position and each have an eccentric axial wire passage opening. The two passage openings are arranged axially one behind the other and are in alignment in the wire release position and are out of alignment in the wire clamping position.
