Abstract:
A handle for a medical instrument having a tubular shaft, comprising:at least one movable first grip element for being connected to a force transmission element axially movable in direction of a longitudinal axis of said tubular shaft to transfer motion of said at least one first movable grip element into an axial motion of said force transmission element, a second grip element, a coupling portion for connecting said tubular shaft with said handle, said coupling portion being pivotable and lockable relative to a handle axis about a pivot axis running transversely to said longitudinal axis of said tubular shaft, said coupling portion being connected to said second grip element, and said at least one movable first grip element being connected to said second grip element so that a relative position between said first grip element and said second grip element is unchanged upon pivoting said coupling portion relative to said handle axis, a control element formed as a double-arm lever, a first lever arm of which being connected to said at least one movable grip element, and a second lever arm of which being connected to said force transmission element, such that motion of said first movable grip element causes a rotation of said control element, wherein said control element translates said rotation into an axial movement of said force transmission element.
