  • Patent number: 10973643
    Abstract: A joint configuration is proposed for a joint endoprosthesis forming a hinge joint, comprising a joint receptacle, which has a joint receptacle surface and a receptacle locking structure, and a joint body, which is receivable in the joint receptacle and has a joint body surface and a body locking structure. The joint receptacle surface and the joint body surface are movable in relation to one another into a position in which the receptacle locking structure and the body locking structure assume a locked position, in which they can be engaged for a locked state between the joint receptacle and the joint body.

  • Publication number: 20200306049
    Abstract: The invention relates to an endoprosthesis shaft system for elongate bones, comprising an anchoring part (10) and a shaft (1), which is formed from module elements that can be coupled by means of a plug-in connection (45), wherein a mutual rotation of the elements along the shaft (1) is adjustable and is blocked by means of an anti-rotation mechanism. In order to adjust the rotation, a rotation piece (5) is provided as a further module element, which has a self-contained rotation adjustment device (6) and a clamping device (7) as a mechanism for blocking the rotation. The rotation piece (5) comprises two end faces for the plug-in connection (45) and a sleeve (77). The invention provides, with the rotation piece, a particular module element for the shaft, which as a structural unit allows both an adjustment of the rotation and a blocking against undesired rotation in a self-contained unit.

  • Publication number: 20200146828
    Abstract: The invention relates to a connecting sleeve for anchoring shafts of two oppositely arranged prostheses, preferably on an elongate bone such as a femur or humerus. The reinforcing sleeve comprises two receiving bushes (1, 2) for one prosthesis shaft each and comprises a separable coupling region (3) arranged therebetween for connection in such a manner as to resist shear forces and rotation. According to the invention, each receiving bush (1, 2) has, on the side thereof facing the coupling region, one fork (31, 32) of a pair of forks that interact with each other, and a fitting block (4) is arranged on a base of the fork, the lateral surfaces (44) of which fitting block have a distance that corresponds to an inner width of the fork, and the lateral surfaces (44) are designed to contact flanks of the fork in a planar manner, at least one fastening screw (5) being arranged transversely through the fork. The fork connection is simpler to produce than the known wedge connection and yet is sufficiently robust.

  • Patent number: 7819224
    Abstract: An assembly is provided for reducing the noise that is generated in the heating gas zone by turbofan engines. The assembly consists of an acoustically absorbent cladding in the heating gas flow channel of the turbofan engine. The cladding includes a plurality of neighboring cavities, into each of which four horns extends. The mouths of the horns are fixed to a perforated cover sheet. The cover sheet forms one wall of the heating gas flow channel.

  • Patent number: 6896219
    Abstract: A process and system for noise reduction in multi-engine propeller-driven aircraft. The parameters of at least two propellers are adjusted with regard to frequency, amplitude, and phase so that the sound fields of the propellers are attenuated or completely extinguished by interference in the area of the closest aircraft fuselage.
