Abstract

A medical instrument includes a hollow shaft (2) with a proximal end (3) connected to a handle (4) and a distal end (5) with a tool (6) arranged with one jaw part (8) pivotable relative to another jaw part (7). A distal end region of the shaft as a tool tip (10) deflects relative to a longitudinal axis (9) via an axially displaceable first actuation element (11) connected to the handle. The pivotable jaw part is adjustable via a second actuation element (13) mounted axially displaceably in the hollow shaft and connected to the handle. The first actuation element and the second actuation element are parallel to each other in the longitudinal axis direction of the shaft and mounted to be guided on each other. One of the two actuation elements is mounted on the inner side. The mutual axial mounting is effected via a pin-and-slot control (19).
