Patent DE-3834958-A1 (DE)
Title: Method for fitting a flexible metal coating, which consists of wires, around a cable core, and a device for carrying out the method
Inventor: ASANOV ALBERT ILIIC
IPC: D07B7/14
Filed: 1988-10-13
Abstract: The method comprises individual wires which are arranged uniformly around a cable core being fastened successively in that two threads are wound onto the core with the individual wires following a single-start helical line, with the same tension and with the contact points of the threads being mutually displaced by half the pitch of the helical line, and by the individual wires being shaped in a corrugated shape (in the form of a shaft). The forming of the curves which form the corrugations (shafts) onto the core is carried out by acting on all the individual wires simultaneously. The device for carrying out the method according to the invention contains a guide (7) for individual wires (5), which guide (7) surrounds a spindle (6) and is located coaxially with respect to it. A means (13) for fitting the curves of individual wires is constructed in the form of a gauge which can rotate, and the device (10) for winding up the threads (11) is provided with guides (17) which are arranged in a plane, which passes through the axis of the core (2), at equal distances from this axis, in such a manner that the points at which the threads (11) run off the guides (17) are displaced in the longitudinal direction of the axis of the core (2) with respect to one another by half of the pitch of the helical line formed by these threads (11). <IMAGE>

Filed: 1989-04-18
Abstract: A fixation system for tubular bone fractures (3, 4) consists of an elongated, flattened fixation element (20) and bone screws (10) connected to each other by means of a screw (11), a cone (16) and a conical segment section (15). The fixation element (20) has an essentially rectangular cross-section and is made of tissue-compatible, high-strength material, in particular implant steel. At least two holes in each of the two end sections (21) of the fixation element (20) extend through its opposing wide faces. The bone screws (10) are inserted through these holes. The fixation element (20) is made in one piece from the two relatively rigid end sections (21) and an intermediate connecting section between them, or from two superimposed parts connected to each other in the end sections. The connecting section (31) is elastic in comparison with the end sections (21), because its cross-section is smaller than that of the end sections (21). This compact fixation device can be implanted under the skin and eliminates transverse forces as well as flexing and torsional moments in the region of the fracture, without the implantation affecting the circulation. In addition, the normal forces in the fracture region can be adjusted as required.
