Patent number: 8603090Abstract: An adjustment tool for an external fixator comprises a fitting element for holding fast a clamping assembly of the external fixator. A positioning clamp is provided for fixing the adjustment tool on a rod of the external fixator near the clamping assembly. A connecting element is attached to the fitting element and the positioning clamp is adapted to move the fitting element towards to or away from the positioning clamp. The fitting element comprises a blocking sleeve adapted to push the uppermost jaw of the clamping assembly in the direction of the longitudinal axis of the clamping assembly to block the second upper most jaw against an abutment portion of the fitting element. The tool further comprises an actuation element within the blocking sleeve to actuate the locking element of the clamping assembly for releasing the rod within the clamping assembly without releasing the bone pin.Type: GrantFiled: September 25, 2012Date of Patent: December 10, 2013Assignee: Stryker Trauma SAInventors: Umesh Verma, Klaus Dorawa, Usha Mathur

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
