20090069853 | Surgical retaining screw - In order to simplify the construction and handling capability of a surgical retaining screw comprising a shaft which has an external thread, a head part which is connected to the shaft securely or movably and has an interior space open towards the upper side located opposite the shaft as well as two openings which are arranged on oppositely located sides of the head part, are open towards the upper side and form a receptacle for a bar-like connecting part, and a clamping screw which can be screwed into the interior space from the upper side in such a manner that it clamps a connecting part placed in the receptacle in this receptacle, it is suggested that the clamping screw be screwed into a screw sleeve which abuts with a conical outer surface tapering towards the upper side of the head part on the complementary conical inner surface of a bearing sleeve surrounding the screw sleeve and that the bearing sleeve be held on the head part to as to be secured against any displacement in the direction towards the upper side. | 03-12-2009 |
20100241164 | Facet joint implant - In a facet joint implant comprising two components adapted in the area of a facet-contacting surface for placement on the outer surface of a facet, and a fastener for joining the two components to each other through a channel in a facet or in two facets lying against each other, in order to facilitate insertion of the implant, it proposed that the fastener be configured as a flexible thread which tensions the two components towards each other such that the components are pressed against the outer surface of the facet against which they lie. | 09-23-2010 |
20110004254 | Magazine for receiving at least one bone screw and bone plate having such a magazine - To facilitate the insertion of bone screws into a bone plate, a magazine for receiving at least one bone screw is proposed, which comprises a device for releasably securing the magazine to a bone plate, a receiving chamber extending continuously from the upper side to the underside of the magazine, a bone screw being arranged in the receiving chamber in such a way that when the magazine is secured to the bone plate, the distal tip of the bone screw is directed at a screw-in opening in the bone plate, and the proximal end of the bone screw is accessible to a screwing-in tool from the upper side of the magazine, and a fixing device for releasably fixing the bone screw in the receiving chamber. The invention also relates to a bone plate having at least one such magazine releasably secured thereto. | 01-06-2011 |
20120041448 | SCREWDRIVER FOR BONE SCREWS - A screwdriver for bone screws is provided, having a handle and rotationally fixedly held thereon a shaft, a free end of which has a non-circular cross section and is insertable in a positively locked manner in a non-circular receiving opening in a head of a bone screw. At least one expander element is mounted to be displaceable in a longitudinal direction in the shaft and to slide, when displaced, along a slide surface in an area of the free end of the shaft such that the at least one expander element projects laterally over a contour of the shaft. The non-circular cross sections of the receiving opening and the free end of the shaft are configured such that the shaft is pressed by the at least one expander element in two areas of the receiving opening that are separate from one another against an inside wall of the receiving opening. | 02-16-2012 |
20120224970 | FLUID PUMP HAVING AT LEAST ONE IMPELLER BLADE AND A SUPPORT DEVICE - The invention relates to a fluid pump comprising at least one impeller blade ( | 09-06-2012 |
20120237353 | COMPRESSIBLE ROTOR FOR A FLUID PUMP - The invention relates to a rotor ( | 09-20-2012 |
20120237357 | ROTOR FOR AN AXIAL FLOW PUMP FOR CONVEYING A FLUID - The invention relates to a rotor for an axial flow pump for conveying a fluid having an axis of rotation and having an impeller blade which has at least one part surface which extends transversely to the axis of rotation and beyond it, wherein the impeller blade has throughgoing webs or a network of webs which connect a different marginal regions of the impeller blades to one another. A good compressibility is hereby achieved in the radial direction with high stability during operation. | 09-20-2012 |
20120308406 | PUMP DEVICE HAVING A DETECTION DEVICE - The invention relates to a pump device having a pump ( | 12-06-2012 |
20130177409 | ROTOR FOR A PUMP, PRODUCED WITH A FIRST ELASTIC MATERIAL - The invention relates to a rotor for a pump, having at least one blade, the rotor being able to be actuated to rotate about an axis of rotation in order to convey a fluid in the axial or radial direction, the rotor being able to be deformed reversibly elastically in the radial direction between a first, radially compressed state and a second, radially expanded state which the rotor adopts without the effect of external forces, and a third state of the rotor being provided in which, in pumping operation under fluid loading, the rotor is deformed from the first state to beyond the second state. | 07-11-2013 |
20130245360 | Implantable Blood Conveying Device, Manipulating Device and Coupling Device - The invention provides an implantable component which is connectable to a manipulating device in a self-retaining manner by means of a coupling device, which provides a first coupling element and a second coupling element. The implantable component can thus be really positioned by the manipulating device which can, for example, already be connected to the implantable component before a therapeutic procedure and can be separated therefrom again after the surgical procedure. This is in particular advantageous with minimally invasive procedures. | 09-19-2013 |
