Definitions

  • the invention relates to a guide wire fixation device for the endovascular treatment of a patient with a holding body, which has a holder for a hemostatic valve and at least one fixation for a guide wire.
  • interventional treatment techniques medical instruments, in particular catheters, guide wires, implants, dilating means and the like, are usually introduced into the patient via the groin.
  • the introductory port is a hemostasis valve, which is usually equipped with a side arm and is often called a "Y-connector.
  • the guide wires used in these interventional techniques serve, on the one hand, the placement of the catheter and, on the other hand, the guidance, placement and operation of the actual treatment agent, ie the implant or the dilatation balloon.
  • it is necessary during the treatment to fix the guide wires so that they do not move unintentionally in the longitudinal direction. On the other hand, however, it is often necessary to make such a shift for readjustment.
  • a fixation device directed to the same target according to WO 2005/072807 A1 is firmly connected to the hemostasis valve.
  • the hemostatic valve is fixed in a bore of the holder and has proximally a clamping device for fixing two guide wires, which are pressed by a spring mechanism against a rail on.
  • a disadvantage of this device is that the fixation device must be attached to the hemostatic valve before the start of the treatment and can not be removed from it during the treatment and that the fixation of the guide wires only knows a closed position. If the guide wires are to be moved again after the fixation, the doctor needs two hands, on the one hand to solve the clamping device, which must be kept in the open position and the other for the manipulation of the guide wires.
  • Fixation device in which the guide wire or wires from the treating

  • the fixing device according to the invention is held on the integrated holding body on a commercial hemostatic valve and held in position. It has at least one fixation for a guide wire, preferably two fixations.
  • the holder is designed as an elastic holding element which can be snapped onto the hemostasis valve.
  • the holder is such that guidewires exiting the hemostasis valve pass through the fixative.
  • the fixing means has an open and a closed position, so that each wire can be fixed with a simple hand movement.

  • each fixation on a flexible tongue, with the help of each guided guide wire is set against a fixed inner wall.
  • the determination is carried out for example via a continuously adjustable screw, in which the extreme positions can be adjusted with less than one revolution of the screw, preferably with less than half a turn of the screw.
  • the elastic holding elements of the holder of the device according to the invention are preferably elastic clips, in particular three elastic clips which are snapped onto the hemostatic valve.
  • Such elastic clips for example, consist of open rings whose opening is about 1/3, preferably about 1/4 of the circumference.
  • the clips are preferably arranged so that the hemostatic valve is held immovably in the longitudinal direction. Nevertheless, a rotation about the longitudinal axis in the holder readily possible.
  • the fixations are expediently arranged on an inner wall of the device, the inner wall lying on the longitudinal axis of the fixation device. This allows the arrangement of the screws on the outside, with their effect is directed inwards against each other.

  • Such a screw has, for example, two mutually offset semicircular turns, engage in the complementarily arranged nubs of the associated screw socket. It allows a cost-effective production of the screw mechanism at the same time simple and safe handling. For safety reasons and to facilitate handling, each screw is self-locking.
