Patent number: 8206388Abstract: An insert for a clamping element having two jaws for clamping a rod-shaped element comprises at least one jacket element. The jacket element can be inserted into one jaw each of the clamping element, thereby allowing the varying, especially reducing, the free space available for a rod. The insert also comprises at least one retaining section which fastens at least one part of the insert in or on at least one of the jaws of the clamping element. A clamping element can be provided with two jacket elements, interlinked via an undulated web, or two or three juxtaposed longitudinal grooves for receiving rods having different diameters.Type: GrantFiled: November 30, 2005Date of Patent: June 26, 2012Assignee: Stryker Trauma S.A.Inventors: Roland Thomke, Damian Fankhauser

Patent number: 8172840Abstract: An external fixation component includes two capture members adapted to capture independently a first and a second element of an external fixation system. A rotation member is provided between the two capture members, coupled to both capture members such that the coupling allows the two capture members to rotate about three axes relative to each other. Each capture member comprises a central locking screw extending therethrough and defining a longitudinal axis of the associated capture member. The rotation member comprises two rotation blockers, each blocker providing one interface surface adapted to be in contact with a complementary interface surface of one of the capture members, each blocker further provides a surface opposite to the interface surface comprising an inner cylindrical surface. The rotation member comprises a central disc element forming a rolling surface as complementary surface to the inner cylindrical surface of the corresponding rotation blocker.Type: GrantFiled: December 21, 2009Date of Patent: May 8, 2012Assignee: Stryker Trauma SAInventors: Beat Mürner, Robert Wider, Roland Thomke, Usha Mathur, Umesh Verma

Patent number: 7806623Abstract: An insert for an external fixation has two jaws for clamping a rod-shaped element. The insert includes a locking element and is an angled piece having two free ends, with at least one engagement edge for engagement into the rod-shaped element being provided at its one free end. The insert has a recess or bore for engagement with a locking shaft of the clamp provided at the free end thereof that lies opposite to the free end having the rod engagement edge. The insert is angled so that it may extend through a passageway in one of the jaws and into a cavity formed in the jaw for receiving the rod. The insert rod engaging edges are tapered to bite into the rod to prevent its movement.Type: GrantFiled: December 10, 2008Date of Patent: October 5, 2010Assignee: Stryker Trauma S.A.Inventors: Roland Thomke, Vinzenz Burgherr, Damian Fankhauser
