The shaft has a longitudinal axis that is angled with respect to the tool axis. A second handle is coupled to the shaft intermediate the head portion and a gripping portion of the shaft for applying a force along the tool axis.

Abstract: A surgical power tool has an actuation assembly which comprises a force sensor and a switch. The force sensor is provided to determine an actuation force produced by the user, and the switch is transferred by the actuation force from a first switching state to a second switching state. A combined evaluation of the force sensor signal and of the switching state enables, for example, a plausibility check for increasing the operational reliability of the power tool.

Abstract: A drill guide system for a bone plate having holes includes a guide block having at least two drill guide bores alignable with a bone screw receiving hole in a bone plate. A locking element extending through at least one drill guide block bore into the bone plate bone screw receiving hole, the locking element having a partially threaded bore portion and having a bifurcated tip surrounding the threaded bore portion. The bifurcated tip capable of engaging an inwardly extending protrusion formed on an internal wall of a bone screw receiving hole in the bone plate. An axially moveable threaded rod has a head for contacting an outer surface of the guide block and an end portion engaging a portion of the bore in the bifurcated tip of the locking element for separating sections of the bifurcated tip on axial movement of the rod prior to the head contacting the second surface of the drill guide block.

Abstract: An implant container for accommodating one or more bone plate implants has a base having a receiving structure configured to receive at least one bone plate implant so that the bone plate implant is held in a defined relationship relative to the base. A lid of the implant container has an opening and is movable relative to the base from a first position to at least a second position. In the first position the lid covers the receiving structure at least partially so as to prevent implant removal, whereas in the second position the lid provides access to the receiving structure via the opening so as to permit implant removal.

Abstract: Bending forceps (10) for surgical elements such as bone plates (30) are described. The bending forceps (10) have two branches (12, 14) which can pivot relative to one another and with together two counter bearings (26, 28) for the surgical element to be bent. A bending punch (32) for co-operation with the surgical element is provided in a region between the two counter bearings (26, 28). An actuating movement (40) of the branches (12, 14) is converted into a linear movement of the bending punch (32) in the direction of the surgical element by means of an actuating device (40), for example an elliptical linkage gear mechanism.

Abstract: Three-dimensional image data generated for an object is representative of at least a portion of the object and of reference markings associated with the object. The reference markings have a known spatial relationship with a registration tracker tracked by a navigation system. Registration tracking data/object tracking data, each representative of at least one of a spatial location and a spatial orientation of the registration tracker/object tracker respectively, are provided. The object tracker has a fixed spatial relationship with the object. The relative position between the registration tracker and the object tracker is calculated from the registration tracking data and the object tracking data for a given point in time. Registered image data is generated representative of the location or the orientation of the object, taking into account the spatial relationship between the reference markings and the registration tracker, and the relative position between the registration tracker and the object tracker.
