摘要:
The invention relates to a method for producing acupuncture needles from sections of metallic wire to the end of one of which a section of metal tube is attached which forms a handle. Customary production methods do not lend themselves to automation and result in high production costs. To be able to produce acupuncture needles in a fully automated manner while continuing to meet all medical requirements the invention provides for a certain length of an end part of the wire section (10) to be pushed through the tube section (12) and to be bent to form a handle end (16), and for said tube section (12) to be pressed against the wire section (10) by radial pressure. Alternatively, after the end part of the wire (10) has been pushed through the tube section (12) said tube section is pressed radially against the end part of the wire and shaped into a radially expanded handle end by means of axial pressure. Both methods allow for the fully automatic production of acupuncture needles at a rate of at least 80 needles per minute using a production device which is easy to construct.

The invention relates to a profile turning tool for roughturning and planing peripheral and plane surfaces, especially on light metal work pieces. The tool comprises a holder (10) with a location (16) for a diamond cutting head (18) and a bracket (20) that engages in a longitudinal groove (26) in the holder (10) and clamps the cutting head (18) by means of an adjusting screw (22), said bracket being configured as a chip breaker. The groove (26) is located directly behind the cutting head (18). Its base, in the longitudinal section, has a rounded off arcuate shape and represents a pivot bearing for the bracket (20) that has a correspondingly shaped underside and is guided on the lateral walls of the groove (26). The adjusting screw (22) extends through a hole in the bracket (20) before the center of the arc, allowing for play.

Die Absperrvorrichtung hat ein Gehäuse (10) und einen Elektromotor (14), der über ein Schraubgetriebe (18, 20) und ein Schubgestänge (22, 24) ein Absperrelement (12) zwischen einer liegenden und einer aufgerichteten Endstellung verschwenkt. Um mit einem verhältnismäßig kleinen Elektromotor auszukommen, ist vorgesehen, daß die Achse des Gelenks (66) zwischen Schubgestänge (22, 24) und Absperrelement (12) im mittleren Bereich der Schwenkbewegung die senkrechte Ebene durch die Schwenkachse (54) des Absperrelements (12) durchquert. Dieses ist durch Anschlagflächen (50, 32) spielfrei oder mit begrenztem Spiel in aufrechter Stellung gehalten. Durch Spiel (70) im Antriebsstrang (18-24) ist es nach dem Anhalten der Absenkbewegung in einer der liegenden angenäherten Stellung um mindestens 3° - 5° zur flachliegenden Stellung hin verschwenkbar.

In the inventive device, a wire (18) is guided by means of a wire guiding device (20) and is wound onto a shaped body (10) of a template (10, 12) which can be rotationally driven. Said shaped body (10) is provided with recesses (16). The wire is cyclically pressed into the recesses (16) during the rotation of the template (10, 12) by means of outer forming elements (12) which can be driven radially. The wave-shaped coil windings are then converted into longitudinal slits of a coil receiver (34) which is axially positioned in front of the forming body (10). Said coil receiver (34) is rotationally fixed in a substantial manner during the winding movements. The aim of the invention is to produce complete winding movements over the circumference in a simple manner. The end of the last winding of a wave winding is formed by means of an additional inwards movement of at least one forming element (12) when said last winding is placed in a swing angle position of the template (10, 12) that is different to the swing angle position in the cyclical forming movement in the allocated recess (16).

A punch guide assembly includes a retaining clip for retaining the stripper plate (6) inside the punch guide (2) or allowing removal thereof without disassembly of any of the remaining components of the punch tool. The retaining clip (7) is easily insertable into the punch guide (2) and removable therefrom through an opening in the sidewall of the punch guide without the use of additional tools.

The invention relates to an instrument for inserting intervertebral implants. Said instrument (1) for a tree-piece intervertebral implant (2) has an upper part (6) that is fastened to the vertebral body, a lower part (9) that is fastened to the adjoining vertebral body and an interposed joint element (14) with two parallel arms (21, 27) that are pivoted with respect to each other at one end and that have, at their free ends, respective holding devices (20) for the upper part (6) and the lower part (9), respectively, of the intervertebral implant (2). The aim of the invention is to improve the ease of insertion of the joint element (14) between the upper part (6) and the lower part (9). To this end, one of the arms is provided with a longitudinal guide element (38, 39) for the joint element (14).

The invention relates to a method and a device for producing a distributed wave winding. To accelerate the currently used method for producing a distributed wave winding the invention provides for a relative indexing to be carried out between the template (12) and coil receiver (38) after a concentric coil group (50) has been ejected and for a further concentric coil group (54) of the same phase with a connection (52) to the previous coil group (50) to be wound on the template (12) and ejected into the coil receiver (38).
