Abstract

A medical instrument with a hollow shaft, at the proximal end of which a handle is arranged, and at the distal end of which a tool is arranged with a stationary jaw part and with a jaw part that is pivotable relative to the stationary jaw part, a distal end region of the shaft that carries the tool being designed as a tool tip that can be positioned at an angle with respect to the longitudinal axis of the shaft, and the tool being rotatable about the longitudinal axis of the shaft respectively about the longitudinal axis of the tool tip. The axially displaceable actuation element for actuating the pivotable jaw part of the tool are coupled to each other in such a way that, on the one hand, when the axially displaceable actuation element for positioning the tool tip at an angle is actuated, the axially displaceable actuation element for actuating the pivotable jaw part of the tool is necessarily movable at the same time in the axial direction, and, on the other hand, the axially displaceable actuation element for actuating the pivotable jaw part of the tool can be actuated independently of the axially displaceable actuation element for positioning the tool tip at an angle.
