Definitions

  • the invention relates to a plug connection for the detachable connection of two bodies according to the preamble of patent claim 1.
  • connection mechanism which has an upwardly open bore with an internal thread and a slot running transversely to the bore axis in the head of the pedicle screw and an external thread corresponding to the internal thread and two cams corresponding to the slot on the manipulation device. In this way, a connection that is fixed with respect to rotation and axial displacement can be established.
  • a bayonet lock, a dovetail-like connection which requires a lateral insertion of the manipulation device into the screw head and then, when the manipulation device is inserted, releasable locking by means of a pin concentric with the screw axis, which can be pushed back and forth by the manipulation device, and a connection with two Cams at the front end of the manipulation device, which engage in a groove on the face of the screw head with a cylindrical backward rotation.
  • a T-shaped slide mounted concentrically to the screw axis in the manipulation device can be inserted axially through the groove and rotated around the screw axis when the backward rotation is reached, so that an axially fixed connection is created between the manipulation device and the screw head.
  • the invention seeks to remedy this.
  • the object of the invention is to produce a connection between the screw and the screwdriver which is secured against tension, shockproof and not weakened in rotation. This is achieved in that the working end of the screwdriver inserted into the screw head has a segment next to the actual screwdriver drive segment that can be wedged in the screw head.
  • the invention solves the problem with a plug connection for the releasable connection of two bodies, which has the features of claim 1.
  • the plug connection according to the invention for the detachable connection of two bodies comprises, on one of the bodies, a first connecting zone with a central axis and M connecting sections which are arranged coaxially with the central axis, and on the other body a second connecting zone with a central axis and N connecting sections.
  • the M and N connection sections are arranged coaxially to the central axis and can be designed in the manner of a pin and / or as recesses on each of the connection zones, so that the first connection zone and the second connection zone form a plug connection which is coaxial with the central axis.
  • the first connection zone comprises at least one connection section with a non-circular cross section and the second connection zone comprises at least one connection section with a non-circular section. circular cross-section positive cross-section. A rotationally stable form fit can thus be achieved relative to the central axis.
  • the plug-in connection is non-positive coaxially with the central axis.
  • the conditions also apply to the number of connecting sections:
  • the first connecting sections are arranged coaxially and have a different shape in the various embodiments of the device according to the invention. These deviations in shape can arise due to differently designed cross sections, such as hexagon, hexagon or circular area, or also due to different diameters with the same cross-sectional shape. This also applies to the second connection sections of the second connection zone on the second body.
  • the plug-in connection comprises, in further embodiments, connecting sections which, in their interaction, bring about an axial force connection and, in turn, further embodiments also stabilize the central axis of the plug connection, in particular the force connection when force is applied.
  • connecting sections which, in their interaction, bring about an axial force connection and, in turn, further embodiments also stabilize the central axis of the plug connection, in particular the force connection when force is applied.
  • Connection zone 1 Connection zone 2
  • the device according to the invention with one of the plug connections comprises a manipulation device as the first body, in particular a screwdriver with the first connection zone, and a screw or an osteosynthetic implant, in particular a bone screw with the second connection zone as the second body.
  • first and second connection zones are interchanged, so that the manipulation device, in particular the screwdriver, comprises the second connection zone and conversely the screw comprises the first connection zone.
  • a frustoconical segment (screwdriver clamp segment) is used as the second connecting section.
  • the drive segment of the screw e.g. hexagon socket
  • a screw-clamping segment is preferably a cylindrical bore with a diameter smaller than the maximum diameter of the frustoconical screwdriver-clamping segment and larger than the corresponding minimum diameter.
  • the angle of the truncated cone is chosen to be so small (2 ° to 10 °) that when the truncated cone-shaped screwdriver clamping segment is pressed into the cylindrical screw clamping segment, wedging takes place with self-locking. The wedging creates a tension-proof connection between the screwdriver and the screw without weakening the rotary drive.
  • connection can come off abruptly when subjected to bending loads.
  • the risk of loosening the wedge connection in the event of bending loads from the rotary drive is reduced: the longer the drive, the greater the stabilizing effect.
  • the screwdriver drive segment always has a certain amount of play in the screw drive segment, the greater this play, the smaller the stabilizing effect on the wedge connection.
  • the influence of the game can, however, be eliminated if, for example, the screwdriver drive segment against the handle is supplemented by a cylindrical stabilizing segment as the third connection zone, and vice versa for the screw head. From a production point of view, the two interlocking, cylindrical stabilizing segments can easily be fitted with a tight fit.
  • Another way to reduce the influence of the play in the drive area is to use a truncated cone-shaped screwdriver clamp segment with a cylindrical stabilizing segment with a diameter smaller than or equal to the smallest diameter of the truncated cone-shaped screwdriver clamp segment.
  • the cylindrical screw clamping segment must be extended by a cylindrical screw stabilizing segment.
  • the two interlocking cylindrical stabilizing segments can have a close fit.
  • the screwdriver comprises an axially resilient pressure pin which is coaxial with its longitudinal axis. After the screw has been screwed in, the pressure pin is pushed forward relative to the screwdriver and pressed against the screw. As a result, the screwdriver can be completely squeezed out of the screw head.
  • the pressure pin can also apply a large pressure force, which arises due to the self-locking of the wedge-shaped connection, in order to release the connection between the screwdriver and the screw.
  • the ejection mechanism has the following advantage compared to standard screwdrivers:
  • Figure 1 is a perspective view of a pin-like connection zone according to an embodiment of the connector according to the invention.
