    • The invention relates to a medical instrument having a hollow shaft, whose proximal end can be connected to an operating unit and having a tool tip arranged at the distal end of the shaft having a tool arranged at the distal end of the tool tip, wherein the tool has two jaw parts, which can be pivoted relative to one another and wherein the jaw parts are pivoted via actuating elements, which are mounted so as to be axially displaceable in the shaft and which can be actuated on the proximal side via the operating unit and wherein the tool tip can be pivoted via a joint mechanism relative to the longitudinal axis of the shaft.
      In order to provide a medical instrument, which ensures a uniform transmission of tensile and compressive forces even via the pivot region to the tool tip, it is proposed according to the invention that the pivotable jaw parts are each coupled via an articulated drive element to the distal end of an actuating element mounted so as to be axially displaceable in the shaft such that the articulated drive element spans the region of the joint mechanism between the distal end of the shaft and the proximal end of the tool tip.

    • This application provides an endoscopic device having at least one shaft with at least one portion deflectable, and having at least one deflection mechanism, which is configured to deflect the deflectable portion and includes at least one first connection member and at least one second connection member. When the connection members are arranged in a straight position relative to each other, a straight-position spacing exists defined by a shortest connection between a geometric midpoint of the first connection member and a geometric midpoint of the second connection member and, when the connection members are arranged in a deflection position relative to each other, a deflection-position spacing exists which is defined by a shortest connection between a geometric midpoint of the first connection member and a geometric midpoint of the second connection member, and the deflection-position spacing in the deflection position is greater than the straight-position spacing in the straight position.
