Abstract:
Rotation joint for medical instruments with a proximal part and a distal part that are coupled to one another by means of a gear work and can be adjusted in relation to one another between a non-deflected starting position and an angled end position, where the gear work is housed in an intermediate part situated between the proximal part and the distal part and separating these parts from one another, and all three parts have at least one hollow center channel running through them, and where the proximal part consists of two tubes that are arranged coaxially inside one another and can rotate independently of one another in opposite directions around their longitudinal axis, where at least an outer of the two tubes is connected with a handle on its proximal side distinguished in that an inner of the two tubes is equipped with a toothed wheel of the gear work and that a steering pin is mounted on the distal-side end surface of the outer of the two tubes, where the steering pin engages into a corresponding recess of the intermediate part.
