摘要:
Die vorliegende Erfindung betrifft ein Implantat zur dauerhaften oder zeitweisen Verbringung in den menschlichen oder tierischen Körper mit einem Grundkörper zur Verbindung beabstandeter Körperteile und/oder anderer Implantatkomponenten, welcher eine Lastachse (L) aufweist, entlang der primär Zug- und/oder Druckkräfte übertragbar sind, wobei senkrecht zur Lastachse mindestens eine Drehachse (D) ausgebildet ist, welche ein zumindest begrenztes Biegen des Grundkörpers um die Drehachse, insbesondere der entlang der Lastachse angeordneten Enden des Grundkörpers, ermöglicht, wobei die mindestens eine Drehachse durch ein Drehgelenk (11, 12, 13, 14, 15) definiert ist, welches einstückig am Grundkörper ausgebildet ist.
摘要:
The invention concerns a method for obtaining a metal implant for open porosity tissue support and/or replacement, characterized in that it includes the following steps: (i) selecting a mold, (ii) arranging in the mold a solid metal core (7), (iii) filling the volume of the mold (1) still available with the powder of microbeads (3), (iv) integrating the microbeads with one other as well as with said at least one solid core (7) by electrical discharge machining.
摘要:
The invention concerns an implant for backbone surgery essentially comprising a hollow body (10) to be inserted in an intervertrebral space, said body having a pair of lateral walls (102, 103) enclosing an internal space exposed to the superjacent and subjacent vertebrae defining said intervertebral space. The implant further comprises an anchoring reinforcement member (20) having on its outer surface bone anchoring projections (22) inscribed in a diameter greater than the body overall height, said member being driven in rotation in the inner space of the body. The invention concerns various improvements to such a two-part implant.
摘要:
An antimicrobial containment cap is provided for use in a bone anchored prosthesis mounting system of the type having an externally protruding fixator pin carried by an implanted bone anchored mounting post, wherein the fixator pin accommodates removable attachment to an exoskeletal prosthesis such as a prosthetic limb or the like for an amputee. The containment cap, when mounted onto the fixator pin, is interposed between the prosthesis and soft tissue covering the end or stump of an amputated residual limb or the like. The containment cap carries and supports a selected antimicrobial or antibacterial agent in substantial contact with the soft stump tissue in a position closely overlying and substantially circumscribing the tissue interface with the externally protruding fixator pin to safeguard against infection. The containment cap is adapted for quick and easy periodic removal for cleaning and/or replenishment of the antimicrobial agent.

Disclosed is an intervertebral implant (1) comprising: A) a bottom implant part (2) that is provided with a hollow cylindrical cavity (3) having a jacket (14) and an axis of rotation (11), and an appositioning part (4) that is to rest against the cover plate of the bordering bottom vertebra; B) a top implant part (5) that is provided with an essentially circular cylindrical shaft (6) which extends into the cavity (3) and encompasses an external thread (7) and an axis of rotation (11), and an appositioning part (8) that is to lean on the cover plate of the bordering upper vertebra, C) the two implant parts (2, 5) being secured against rotation about the axis of rotation (11) thereof; D) an internally threaded ring (9) which is disposed between the two implant parts (2, 5) and cooperates with the external thread (7). E) The two implant parts (2, 5) and the ring (9) are coaxially arranged along the common axis of rotation (11) thereof such that the distance between the two appositioning parts (4, 8) can be infinitely varied by twisting the ring (9) on the external thread (7) of the shaft (6). F) The ring (9) is connected in an axially fixed but rotationally movable manner to the bottom implant part (2). The inventive intervertebral implant allows for simplified handling, which increases safety while reducing the time required for the implant to be implanted.
摘要:
A method and device for assembling a multi-phase implant for insertion into a patient defect site that spans more than one tissue type. The assembly device comprises a base portion (20) and cover portion (30) for constructing a two-phase implant separated by a membrane (23). A repeating intermediate portion (40) that connects the base (20) and cover (30) can be used to construct implants with more than two phases, with each phase separated by a membrane (23). The invention is also for multi-phase implants, wherein adjacent phases are separated by a membrane. In an embodiment, the implant phases are selectively loaded with a bioactive agent selected to promote tissue repair in the tissue surrounding each phase.
摘要:
Intervetebral fusion cage comprising a prismatic, conical or cylindrical cage (1) having A) a central axis (2); B) an upper and lower bone contact surface (3; 4) transverse to said central axis (2); C) a central cavity (5) for receiving bone graft material and extending between said lower contact surface (4) and said upper contact surface (3) through said body (1) defining a circumferential sidewall (10) arranged coaxially to said central axis (2); and D) a plurality of sectorial slots (6; 7; 8; 9) perforating the circumferential sidewall (10) transversely to the central axis (2), whereby E) said slots (6; 7; 8; 9) have a minima width (h1; h2; h3, h4) that upon compressing of the body (1) along the central axis (2) said slots (6; 7; 8; 9) close elastically at the minimal widths (h1; h2; h3; h4) thereby increasing the stiffeness of the cage (1) upon further compression.
