Publication number: 20130211386Abstract: A targeting system is used for positioning of a medical sub device with respect to a medical device. A reference body is reproducibly positioned with respect to a targeting device coupling section and reproducibly positioned with respect to a targeting unit. The targeting unit has a targeting direction and is adjustable with respect to the targeting device so that the targeting direction points toward a medical sub device receptacle of the medical device coupled to the targeting device coupling section. The imaging system is positionable with respect to the targeting device such that the imaging system is capable of imaging a single two-dimensional view of the reference body and the medical sub device receptacle. The evaluation unit generates position data of the single two-dimensional view and to determine from the position data a lateral distance between the targeting direction and a receiving direction of the medical sub device receptacle.Type: ApplicationFiled: July 16, 2010Publication date: August 15, 2013Applicant: STRYKER TRAUMA GMBHInventors: Arno Blau, Bernd Simon, Michael Kohnen

Publication number: 20130144299Abstract: An anchorage in tissue is produced by holding a vibrating element and a counter element against each other such that their contact faces are in contact with each other, wherein at least one of the contact faces includes a thermoplastic material which is liquefiable by mechanical vibration. While holding and then moving the two elements against each other, the vibrating element is vibrated and due to the vibration the thermoplastic material is liquefied between the contact faces, and due to the relative movement is made to flow from between the contact faces and to penetrate tissue located adjacent to outer edges of the contact faces. For liquefaction of the thermoplastic material and for displacing it from between the contact faces, no force needs to act on the tissue surface which is to be penetrated by the liquefied material.Type: ApplicationFiled: January 30, 2013Publication date: June 6, 2013Applicants: STRYKER TRAUMA GMBH, WOODWELDING AGInventors: WOODWELDING AG, STRYKER TRAUMA GMBH

Patent number: 8449581Abstract: A bone plate that may be used to maintain relative position of two pieces of fractured bone, for example, a fractured jaw bone. The bone plate has a slot and holes. The holes are surrounded by walls and the slot is also surrounded by walls. The thickness of walls surrounding the slot at their maximum is greater than the thickness of walls surrounding the holes. Often the nature of the fracture may require bending of the plate for implanting it as desired by the surgeon. Because walls of the slot are designed to be strong, the slot is not deformed when the plate is bent.Type: GrantFiled: May 7, 2007Date of Patent: May 28, 2013Assignee: Stryker Trauma GmbHInventor: Alwin Van Helfteren

Patent number: 8403938Abstract: An anchorage in tissue is produced by holding a vibrating element and a counter element against each other such that their contact faces are in contact with each other, wherein at least one of the contact faces comprises a thermoplastic material which is liquefiable by mechanical vibration. While holding and then moving the two elements against each other, the vibrating element is vibrated and due to the vibration the thermoplastic material is liquefied between the contract faces, and due to the relative movement is made to flow from between the contact faces and to penetrate tissue located adjacent to outer edges of the contact faces. For liquefaction of the thermoplastic material and for displacing it from between the contact faces no force needs to act on the tissue surface which is to be penetrated by the liquefied material. For this reason anchorage in tissue which has little mechanical stability is possible.Type: GrantFiled: October 29, 2008Date of Patent: March 26, 2013Assignees: Woodwelding AG, Stryker Trauma GmbHInventors: Marcel Aeschlimann, Laurent Torriani, Mario Lehmann, Jörg Mayer, Richard Lum, Kyle Craig Pilgeram, Michael Baycura, Lisa Ballou

Publication number: 20130072931Abstract: A method for implanting a longitudinal intramedullary nail into the tibia comprises inserting the tibia nail along a plane of symmetry through the tuberositas tibiae. Thereby, the tuberositas tibiae can be used during nail insertion to correctly align the nail and the target arm to the symmetry plane of the bone. This means, that the whole construct, the nail attached to the target arm, has to be inserted in external rotation.Type: ApplicationFiled: September 16, 2011Publication date: March 21, 2013Applicant: Stryker Trauma GmbHInventors: Annika Homeier, Ilan Howling, Nils Zander, Lothar Kühne, Claudia Graca

Patent number: 8398636Abstract: A hip fracture device providing distance limited dynamization, load controlled dynamization and combinations of both dynamization methods by varying components. The hip fracture device includes a plate having a head portion and a shaft portion. A barrel projects from the head portion of the plate and a screw is inserted in the barrel. A friction pin is slidably connected with the screw, and an end cap is fixed to the head portion of the plate. The friction pin is fixedly connected with the end cap. The screw slides over the friction pin and toward the end cap when a load is applied on the fracture device. The load required for further sliding of the screw over the friction pin increases incrementally as the screw slides towards the end cap.Type: GrantFiled: April 11, 2008Date of Patent: March 19, 2013Assignee: Stryker Trauma GmbHInventors: Bernd Simon, Jakob Kemper, Carsten Hoffmann
