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

Patent number: 11476739Abstract: In a method for manufacturing lamination stacks of controlled height in a tool, starting material is provided as continuous strip delivered from a coil or as an individual sheet. Laminations are punched from the starting material in several punching steps to a required contour of the laminations. A heat-curing adhesive is applied onto the laminations prior to performing a last punching step. The laminations are combined to a lamination stack. The laminations of the lamination stack are partially or completely heated in a lamination storage. The adhesive is liquefied by heating the lamination stack to build up adhesion and then solidified. Curing the adhesive at the liquefying temperature or solidifying the adhesive in the tool by cooling and subsequently heating the adhesive to a temperature below the liquefying temperature is possible so that the adhesive does not melt but undergoes further curing resulting in higher temperature stability.Type: GrantFiled: May 20, 2021Date of Patent: October 18, 2022Assignee: Kienle + Spiess GmbHInventors: Daniel Blocher, Steffen Bauer, Andras Bardos

Patent number: 9531223Abstract: The stack of laminations consists of punched laminations (5), which are bonded together by an adhesive agent. The adhesive agent is composed of an adhesive (4) and an initiator (15), which consists of methacrylates, derivative imines and methacrylic esters. The completely cured adhesive bond has long-term resistance when exposed to a temperature of at least over 80° C. The adhesive (4) is applied over the full surface area and in a contacting manner to one side of the lamination (5) and the initiator (15) is applied to the same side and/or to the other side of the lamination (5). The initiator (15) reacts with the adhesive (4) when contact is made and establishes the adhesive connection between laminations (5) lying against one another. The adhesive agent may, however, also be an adhesive (4) that cures by itself when heat is applied.Type: GrantFiled: March 13, 2013Date of Patent: December 27, 2016Assignee: Kienle + Spiess GmbHInventors: Daniel Blocher, Steffen Bauer, Andras Bardos

Patent number: 8474129Abstract: Lamination packs of a controlled height are produced in that laminations are punched with a tool and glue is applied partially onto at least one of an upper surface and a lower surface of each of the laminations without the application device that applies the glue contacting the laminations. Several of the laminations are then assembled to a lamination pack. Height of the lamination packs is controlled by interrupting the application of glue for certain laminations so that between some of the laminations that are stacked for assembling a lamination pack there is no glue.Type: GrantFiled: March 9, 2007Date of Patent: July 2, 2013Assignee: Kienle + Spiess Stanz- und Druckgiesswerk GmbHInventors: Daniel Blocher, Steffen Bauer
