  • Patent number: 10398534
    Abstract: The invention relates to an implant (10) for anchoring in the human or animal maxilla or mandible, a device (100) (an instrument) for bending an implant, a system, which includes an implant (10) and a device (100) for bending an implant, and a method for bending an implant. As a result of the bending geometry, an implant (10) is provided which is bendable in a simple and materially-careful manner, in particular after implantation, i.e., already anchored in the jaw bone. The device (100) for bending the implant (10) enables, due to the pliers-shaped design having corresponding holding (113) and support (123) units, the bending of the implant in a simple manner, in particular the bending after implantation thereof, so that a treatment which protects the implantation region is ensured, in particular, no damage of the bone bed is induced. In addition, a method for bending the implant (10) is provided.

  • Patent number: 6634164
    Abstract: An apparatus for manufacturing stranded cables from strand elements with alternating twist directions (SZ stranding). One or more storage disks can be disposed between a guide that receives the strand elements and a stranding disk. The stranding disk and the storage disks can be driven in alternating directions. At least one torsion element drives the storage disks with a respective rotation speed that decreases with increasing distance between the storage disks and the stranding disk. The torsion element can be driven at several locations with a different rotation speed.

  • Patent number: 6168632
    Abstract: A femur component of a hip joint endoprosthesis which has a shaft (1) for anchoring in the medullary cavity of the femur. The shaft (1) has a distal section (9) and a proximal section (8), to which is connected a collar section (2) with a peg (3) for receiving an articular head, or with an articular head which is firmly attached to the collar section (2). The shaft (1) has a front surface (4), a rear surface (5), a lateral side (6), a mesial side (7) and a plane of symmetry (11), whereby longitudinal ribs (10) which stretch from proximal to distal are fitted on the front surface (4) and the rear surface (5) in the proximal section (8) of the shaft (1). The crests (12) of the longitudinal ribs (10) form an angle &dgr;/2 of at least 1° to the plane of symmetry (11), and the envelope of the crests (123) of the longitudinal ribs (10) forms a double wedge-like or ellipsoid body, which tapers both toward the lateral side (6) and the mesial side (7).

  • Patent number: 5674072
    Abstract: Mechanical joining of a two-phase tooth implant, consisting of two components which are joined by means of a conical pin projecting into a conical sleeve, the cone pairing being realized within the self-locking region and the cone pin being penetrated by a centrally aligned, tension screw reduced diameter which tensions the pair of cones against each other. The design permits the two implant components in a two-phase tooth implant to be steplessly positioned in the circumferential direction and to be joined in an anti-rotation, gap-free joint. The required degree of miniaturization, with a sufficient component strength, is achieved through the use of a cone combination in the self-locking region and through the use of a tension screw in the region of the cone joint. By these means, the mechanical, aesthetic and hygienic requirements for a two-phase tooth implant are better fulfilled than in the case of the known designs.

  • Patent number: 5645604
    Abstract: With the invention there is shown a C-shaped clip as a compression member (8) which can be inserted into a pocket (15) of a joint support (4) and which can itself be secured in this pocket against falling out of place by a latched arrangement. In this arrangement the two limbs of the clip act transversely to their spring direction as a spacer between a spring tongue (5) and a shoulder which are formed on the joint support (4). In this way a simple securing device arises which is recessed in the joint support (4) and which prevents springing back of the latched spring tongue (5) and is only loaded in compression. In the installed state the spring tongue (5) is not itself subjected to any alternating bending loads.

  • Patent number: 5330535
    Abstract: A screw-nut for screwing implants together includes a thrust-shoulder which projects radially and presses axially against part of a housing. The screw-nut further includes an internal threaded portion adapted to fit a corresponding screw part, and a plurality of members, each mounted onto the side of the thrust-shoulder facing away from the part of the housing against which the thrust shoulder presses. These members are adapted to receive a tool for tightening the screw-nut. A plurality of leaf springs is included for engaging the housing part. The leaf springs, the ends of which form latching-in dogs, project, in the axial direction, from the screw-nut. The leaf springs are constructed such that, when the thrust-shoulder makes contact with the housing part, each latching-in dog snaps into a recess in the housing part in order to prevent loosening of the screw-nut from the housing part.

  • Patent number: 5314483
    Abstract: With the invention is shown an artificial knee joint, in which the rear cruciate ligament and the collateral ligaments are assumed as being retained. A metal platform is attached to the tibia and perpendicular to the tibia axis has a plane surface, on which three slide members are slidably disposed so as to guide the metal platform relative to the femur condyles made of metal within the limits of the degree of freedom remaining to them under the tension of the ligaments. A central slide member forms an eminentia rotatable around a pin, which guides the femur condyles directly or indirectly with respect to rotation around the tibia axis and which along its median line, which extends in the sagittal direction in the non-rotated central position, forms a direct or indirect longitudinal guiding device for the femur condyles, while the flexion movement is guided at doubly curved femur condyles by the two outer slide members.

  • Patent number: 5282870
    Abstract: An artificial knee joint has a convex femoral part (1) and tibial part (2). At the femoral part (1), which has smaller radii of curvature as bending increases, the tibial part (2) performs a rolling and sliding movement, with the femoral part (1) and the tibial part (2) each comprising a lateral guide surface (F.sub.2, F.sub.2 ') and a medial guide surface (F.sub.1, F.sub.1 '). The medial guide surface (F.sub.1 ') of the tibial part (2) forms a flat guide plane, which with different flex angles, abuts cylindrical guide surfaces (F.sub.1) of the femoral part (1) with line contact, while the lateral guide surface (F.sub.2 ') of the tibial part is trapped by the lateral condyle with different bending angles in the frontal plane in the lateral direction by line contact along circular segments having the same radius of curvature (R.sub.3). The value of this same radius of curvature (R.sub.3) lies between the smallest and largest flex radius (R.sub.n) of the lateral condyle in the track (7).
