Patent number: 11925375Abstract: The invention relates to a medical instrument having an elongated shaft, a movable tool at a distal end of the shaft, a handle with a movable grip part at a proximal end of the shaft, and a force transmission element which can be moved in the longitudinal direction of the instrument and is operatively connected to the movable grip part and to the tool such that an actuation of the movable grip part is converted into a movement of the tool. The instrument has a spring assembly that is arranged on the handle and has at least one leg spring, which has at least one winding and two legs, and a pin, wherein the at least one winding extends about the pin. When the movable grip part is actuated, a force is applied to at least one of the legs of the leg spring, said force reducing the friction between the winding and the pin such that the leg spring can be rotated about the pin and the force transmission element and the tool can be moved.Type: GrantFiled: July 5, 2021Date of Patent: March 12, 2024Assignee: KARL STORZ SE & Co. KGInventors: Janosz Schneider, Jochen Stefan, Daniel Kärcher, Robin Merz, Sven Axel Grüner, Martin Blocher, Sven Schneider, Tobias Unger, Dominik Längle, Judith Holzer, Sebastian Wagner
