Patent number: 10940009Abstract: The invention relates to a joint socket for a joint endoprosthesis, in particular in the form of a hip joint socket for a hip joint endoprosthesis. The joint socket has the form or substantially the form of a section of a hollow-spherical shell. The joint socket comprises a socket wall, in which socket wall at least one through-opening is formed. The through-opening is closed with a closure element. The closure element is formed as one piece with the socket wall. At least one predetermined breaking point is formed between the closure element and the socket wall. The at least one predetermined breaking point is irreversibly destroyable for removing the closure element from the socket wall. The joint socket comprises at least one connecting device for force- and/or form-fittingly connecting the closure element removed from the socket wall to the socket wall in a connecting position.Type: GrantFiled: January 29, 2019Date of Patent: March 9, 2021Assignee: Aesculap AGInventors: Tanja Broghammer, Joerg Fritzsche, Jens Schneider, Kai Bisser

Patent number: 9670836Abstract: A drive unit for a motor vehicle that has a combustion machine having an internal combustion engine (10) as well as an exhaust gas system via which exhaust gas can be discharged from the internal combustion engine (10), and has a cyclic device that can be used to convert the thermal energy contained in the exhaust gas into mechanical work in a clockwise thermodynamic cycle, whereby the cycle comprises a heat transfer from the exhaust gas to a working medium in a first heat exchange device, as a result of which the temperature and/or the pressure of the working medium is increased, comprises an expansion of the working medium in an expansion device (30) for generating the mechanical work, and comprises a heat transfer from the working medium to a cooling medium in a second heat exchange device.Type: GrantFiled: July 9, 2014Date of Patent: June 6, 2017Assignee: VOLKSWAGEN AKTIENGESELLSCHAFTInventors: Asmus Carstensen, Marcus Dallmann, Jörg Fritzsche, Andreas Herr, Christoph Käppner, Thomas Schulenburg, Artur Semke, Jörg Volkmann

Patent number: 8454611Abstract: A modular prosthesis rasp is provided, having a rasp body with a rasp main body and at least one modular rasp body part connectable to the main body. The rasp main body has a receptacle for receiving the at least one rasp body part. An outer contour is defined by the rasp main body and the at least one rasp body part. The rasp body part receptacle extends from an indentation, defining a distal end of the receptacle, on a lateral side of the rasp main body to a proximal end thereof. A first tangential plane of the lateral side of the outer contour in the region of the indentation and a second tangential plane at a rasp body part contact surface, in the region of the distal end of the receptacle include an indentation angle of less than 85°.Type: GrantFiled: December 21, 2010Date of Patent: June 4, 2013Assignee: Aesculap AGInventors: Stefan Wallstein, Joerg Fritzsche

Publication number: 20110160733Abstract: A modular prosthesis rasp comprises a rasp body having a rasp main body and at least one modular rasp body part connectable to the rasp main body. The rasp main body comprises a rasp body part receptacle for receiving the at least one rasp body part in a connected position in which the rasp main body and the at least one rasp body part are connected to each other, and in which the rasp body defines an outer contour defined partly by the rasp main body and partly by the at least one rasp body part. The rasp body part receptacle extends from an indentation, defining a distal end of the rasp body part receptacle, on a lateral side of the rasp main body to a proximal end of the rasp main body.Type: ApplicationFiled: December 21, 2010Publication date: June 30, 2011Applicant: AESCULAP AGInventors: Stefan Wallstein, Joerg Fritzsche
