Patent number: 8845650Abstract: Setting instrument (10) for a hip socket or shoulder socket inlay, having a handle part (11) and a suction element (12) that can be brought into sealing contact with the joint surface. The suction element (12) comprises a flexible molded part (13) matched to the joint surface, which molded part is deformable by a pulling element (14) in such a way that, when applied to the joint surface, an (increased) partial vacuum is formed between the joint surface and the flexible molded part (13).Type: GrantFiled: September 24, 2009Date of Patent: September 30, 2014Assignee: Smith & Nephew Orthopaedics AGInventors: Martin Imhof-Röthlin, René Brack

Patent number: 8556898Abstract: The application relates to a method of orienting a bone-milling cutter and an impact instrument for a hip-prosthesis cup in an acetabulum. The method includes initially positioning a manipulation cup by a manipulation joint head and representing this position by at least one guide rod or fixation rod that is fixed in a bone. The method also includes removing the manipulation cup and adjusting a position of both the bone-milling cutter and the impact instrument with respect to either the guide rod itself or a guide rod that is attached to a holding device disposed on at least one fixation rod.Type: GrantFiled: October 7, 2010Date of Patent: October 15, 2013Assignee: Smith and Nephew Orthopaedics AGInventors: Reinhard Graf, Martin Imhof, Rene Brack

Patent number: 8287549Abstract: An instrument for handling a joint component of a joint prosthesis, which joint component includes a joint surface, includes a grip portion, a suction element in the form of a suction cup with an air-vent opening, the suction cup being placeable in a sealing manner against the joint surface, and a pressure-relief valve associated with the air-vent opening of the suction cup. The pressure-relief valve is coupled to an actuating element which is arranged so as to be movable in the region of the grip surface of the grip portion and, when gripped with one hand, is actuatable with a finger or the thumb of that hand, so that on actuation of the actuating element the valve is lifted away from the air-vent opening.Type: GrantFiled: August 8, 2006Date of Patent: October 16, 2012Assignee: Smith and Nephew Orthopaedics AGInventors: Martin Imhof, Beat Bütler, René Brack

Patent number: 7101401Abstract: Tibial component (10) of a knee-joint endoprosthesis with a flat tibial bearing surface (11), a bearing body (12) that is slidably seated thereon and comprises two concave bearing dishes (13) in which a femoral component can be movably seated, and with a rotational guide means that guides the rotation of the bearing body (12) on the tibial bearing surface (11) about an axis (14) perpendicular thereto. The guide means comprises a bearing post (15) in the form of a regular cylinder that stands upright on the tibial bearing surface (11) and has at least one projection (16, 17) extending radially outward. The bearing post so constructed can be inserted into a post receptacle (19) that is formed on the underside of the bearing body (12) with a receiving groove (20) corresponding to the post projection (16, 17). The at least one post projection (16, 17) extending radially outward is spaced apart from the free end (24) of the post.Type: GrantFiled: January 7, 2003Date of Patent: September 5, 2006Assignee: Plus Orthopedics AGInventor: René Brack

Publication number: 20050107799Abstract: The invention relates to an accessory for implanting a hip endoprosthesis, which comprises a manipulation cavity (20), a manipulation head (16) with means (22) for aligning the manipulation cavity (20) in the acetabulum (12), and a device for immobilizing the aligned position of the manipulation cavity (20). The inventive device allows for the corresponding alignment of a bone bur (28) and a drive-in instrument (27) for placing the acetabular cavity.Type: ApplicationFiled: January 3, 2003Publication date: May 19, 2005Inventors: Reinhard Graf, Martin Imhof, Rene Brack

Patent number: 6755864Abstract: A tibia part for a knee joint prosthesis. The prosthesis includes a tibia bearing surface for the support of a bearing body and a bore for the reception of a guiding element. A cut-out for the rear cruciate ligament is provided in the tibia bearing surface and the bore is formed in such a manner that it can, depending on the design of the guiding element, receive the latter either rotationally fixedly relative to the tibia part or rotatably relative to the tibia part.Type: GrantFiled: September 22, 2000Date of Patent: June 29, 2004Assignee: Sulzer Orthopedics Ltd.Inventors: René Brack, Roger Scherrer, Vincent Leclercq

Patent number: 6099570Abstract: A knee joint prosthesis (1) comprises a tibia part (1) having a tibia bearing surface (10) and a bearing body (3) which is slidingly displaceably journalled on the tibia bearing surface (10) and which has bearing scallops (31) on its side which is remote from the tibia bearing surface (10). Furthermore, it comprises a femur part (5) which is movably arranged on the bearing scallops (31) of the bearing body (3) as well as comprising a guide piece (2) which is arranged to be rotationally fixed relative to the tibia part (1) and which permits only a displacement of the bearing body (3) in the sagittal direction relative to the tibia bearing surface (1). Furthermore, it comprises a coupling member which cooperates both with the guide piece (2) and with the femur part (5) and permits a rotation of the femur part (5) on the bearing body (3).Type: GrantFiled: October 26, 1998Date of Patent: August 8, 2000Assignee: Sulzer Orthopaedie AGInventors: Pacsal Livet, Heribert Frei, Rene Brack
