20140005787 | INTERVERTEBRAL FUSION IMPLANT | 01-02-2014 |
20140039635 | JOINT PROSTHESIS HAVING A BENDING HINGE THAT COMPRISES A SPREADING AXLE - A joint prosthesis has a bending hinge, which is formed by a hinge fork and an axle pin, which comprises two axle stubs, which are arranged in an installation position for insertion, in which installation position the axle stubs are retracted in a coupling piece, and in an expanded position after implantation by movement in the axial direction into aligned hinge holes of the hinge fork, wherein the axle pin has two bearing areas at the ends of the axle pin and a joining area lying therebetween, and the axle pin is separated in the joining area along a plane extending in the axial direction, which plane intersects with the jacket of the axle pin at two points. | 02-06-2014 |
20140046331 | EQUIPMENT FOR INSERTING A JOINT PROSTHESIS, IN PARTICULAR A KNEE PROSTHESIS - Equipment for inserting a joint prosthesis, in particular a femur component of a knee prosthesis, comprises a base frame having a guiding plate and a laterally protruding primary gage, a fastening device on the bone, and a curved milling gage having a main body and a guiding piece, which can be moved along a curved guiding path relative to the main body and has a receptacle for an abrasive tool. Furthermore, the equipment comprises an aligning device, which places the curved milling gage in a clearly defined relative position when the curved milling gage is inserted into the base frame. Due to the precise positioning in conjunction with the curved guiding path, the mounting seat can be prepared easily without damaging surrounding tissue. Thus, even large and complexly shaped prostheses, such as knee joint prosthesis, can be reproducibly inserted in an easy and safe manner. | 02-13-2014 |
20140088639 | SURGICAL FORCEPS WHICH CAN BE TAKEN APART - A pair of surgical forceps which can be taken apart and which includes a handle, a pivot joint with a rotational axis and a jaw. It further includes two releasably coupled forceps parts, each of which has a pin-less pivot joint element. The first pivot joint element has a first guide rail and a first guide recess. The second pivot joint element has a second guide rail and a second guide recess. The guide rails, which engage in an undercut of the guide recesses on the pivot joint elements, form a sliding guide for the pivot joint. The first pivot joint element has a first thickening element and the second pivot joint element has a second surface element. In a safety position the first thickening element interacts with the second surface element by means of clamping. | 03-27-2014 |
20140148913 | ROTARY JOINT PROSTHESIS HAVING A REINFORCED BEARING BUSH - A joint prosthesis comprises a distal component for anchoring to a first bone, a proximal component for anchoring to a second bone, and a coupling piece that, together with the first component, forms a flexion bearing around a first axis and, together with the second component, forms a rotary bearing formed by the pin and the bearing bush around a second axis oriented transversely to the first axis. The rotary bearing comprises a multi-layer bearing insert, having a sliding sleeve surrounding the pin and a support sleeve that encloses said sliding sleeve and is fastened to the coupling piece by means of a securing element, wherein the securing element comprises an actuation unit within the support sleeve and can be connected to the coupling piece such as to ensure tensile strength by means of two aligned bores in the support sleeve and the coupling piece. | 05-29-2014 |
20140180419 | CONTINUOUSLY HEIGHT-ADJUSTABLE INTERVERTEBRAL FUSION IMPLANT - The invention relates to an intervertebral fusion implant for fusing two adjacent vertebrae, comprising a base piece and a cover piece and also a spreading means, wherein the base piece and the cover piece are connected by a rocker which is situated therebetween and externally coupled, and the spreading means is a spreader clip on the rocker and a drive device is provided for the spreader clip. The spreader clip is used to erect the rocker such that the implant expands in terms of height. As a result of the external coupling of the rocker, a large lifting travel is available. Furthermore, the spreader clip has a blocking effect in relation to an unwanted return as a result of the frictional forces thereof. | 06-26-2014 |
20140188224 | LATERALLY EXPANDABLE INTERVERTEBRAL FUSION IMPLANT - The invention relates to an intervertebral fusion implant for fusing two adjacent vertebrae, comprising an adjustable support body, the base surface and cover surface of which are configured to bear on end plates of the adjacent vertebrae, wherein provision is made for a side bracket, which can be pivoted laterally about a hinge and the base and cover of which have a planar design, and provision is made for an actuator for pivoting out the side bracket into a position (working position) spread from the support body. As a result, the implant has particularly small dimensions and can, after assembly at the envisaged implantation site, be actuated in such a way that it becomes larger and thereby affords a larger support surface for support in the intervertebral space. Thus, even comparatively large-area defects can be treated by minimally invasive surgery. | 07-03-2014 |
20140188225 | INTERVERTEBRAL CAGE EXPANDABLE IN STEPS - An intervertebral fusion implant for fusion of two adjacent vertebrae, comprising a base piece and a cover piece, which are each designed to bear on a facing end plate of one of the adjacent vertebrae, wherein the cover piece is adjustable in height with respect to the base piece, wherein a ratchet mechanism, provided between base piece and cover piece, effects a stepped adjustment of height and secures an adopted height against reversal. In this way, a defined expansion can be achieved that is dependent on the number of actuations. A precise control of the state of expansion is permitted, specifically in a purely haptic manner. Moreover, a locking of the adopted state of expansion is achieved with the ratchet mechanism. | 07-03-2014 |
20140324054 | DEVICE FOR DEFINING A CUTTING PLANE FOR A BONE RESECTION - An adjustable device for defining a cutting plane for bone resection comprising a base positionable on the bone and a cut-guiding element placeable on the base. The cut-guiding element includes a cut-guiding structure for guiding a cutting tool in the cutting plane, the cut-guiding element being tiltable relative to the base about at least one first axis by an adjustable tilt mechanism to adjust the angle of the cutting plane. The tilt mechanism includes a rectilinear guide and a slide that is linearly displaceable along the guide in the longitudinal direction. The tilt mechanism includes a guide portion relative to which an effective portion of the slide is displaced; the guide portion and the effective portion having interacting structures forming a sliding guide effective at a right angle to the longitudinal direction. | 10-30-2014 |
20150032114 | Cutting Guide for Generating an Outer Contour for a Joint Endoprosthesis - A cutting guide with a sagittal guide plate is made available for generating an outer contour on a bone in order to apply a joint endoprosthesis, in particular a femoral component of a knee endoprosthesis. The cutting guide according to the invention can be oriented relative to the bone and has at least two sagittal guide slits for guiding a bone-cutting tool, wherein the sagittal guide slits extend through the sagittal guide plate and are arranged at an angle to each other. | 01-29-2015 |
