Abstract
A medical instrument includes a handle with a fixed part and a movable part. A shaft extends between a proximal end and a distal end. The proximal end is releasably connected to the handle. The distal end has an instrument jaw that is openable and/or closable by actuation of the movable part. A push-pull element is guided axially in a cavity of the shaft and operatively connected proximally to the movable part and distally to the instrument jaw. The proximal end has an opening leading into the cavity that is configured for introducing a fluid flow in the direction of the distal end. A functional element is arranged in the cavity and has a plurality of vanes arranged offset in the circumferential direction of the shaft. The vanes are configured to generate, in the fluid flow, a swirling motion oriented in the circumferential direction of the shaft.
