Definitions

  • Anchoring device for guidance in a skull borehole
  • the present invention relates to an anchoring device for anchoring a conduit in a skull borehole according to the preamble of patent claims 1 and 15, respectively.
  • Various methods and agents for cerebellar diagnostics and / or therapy are known in the art which require guidance through a skull of a skull. Examples include electrical brain stimulation devices, blood flow and blood flow measurements, pressure measurements, drug delivery, and tissue fluid aspiration.
  • the line is thereby fixed or anchored in the borehole to avoid accidental injury to the brain. In particular, movements in the longitudinal direction of the line should be avoided.
  • screwable anti-crush devices are used.
  • Various anchoring devices are known in the art. There are devices that are located under the scalp. In this case, the conduit generally still travels a certain distance between the skull and scalp along the skull before exiting the scalp. In other applications, the anchoring device penetrates the scalp. The line is then usually glued with appropriate adhesive tape on the scalp.
  • Such anchoring devices are known for example from US Pat. No. 6,923,799, US Pat. No. 4,677,985 and US Pat. No. 7,553,290.
  • US Pat. No. 6,044,304 describes an annular base part with a central perforated plate, through whose holes the conduit can be led out.

  • US 5 843 150 shows a base part and an upwardly open cover.
  • the lid has on the side a passage opening for the passage of the line.
  • US 5 927 277 uses a clamping ring insert in the base part and the conduit is led out of the skull through a lateral recess in the base part. The opening is closed here with a plug.
  • US 2005/0182464 discloses still further, relatively complicated built-up devices.

  • the base part has a fixing element for fixing the base part in the borehole and a passage opening for passing the line out of the borehole to an outside of the anchoring device.
  • In the base part is a between borehole and outside extending contact surface for installation of the line available.
  • the contact surface is formed in a constant direction gelkrümmt, so that the line in the same direction and with a radius of curvature which is equal to or greater than a predefined minimum Radius of curvature is guided from the inside of the skull to the outside.
  • the curvature preferably runs continuously, ie steplessly and is preferably bent towards the longitudinal central axis of the device.
  • the entire arrangement is preferably aligned centrally with respect to the longitudinal central axis of the device.
  • the device according to the invention not only fixes the conduit, but also prevents it from being squeezed or kinked. Since the lines are not bent too much and thus a crushing or kinking is impossible, their functionality is guaranteed. This is especially important for drainage hoses and fiber optic cables.
  • anchoring device is used in the following: The same device is also called a "port” or “lock.” Under the heading of a conduit, a probe, a catheter, a drainage tube, an electrode or a different type of conduit is understood.

  • This can be done, for example, with at least reach a radially outwardly projecting nose.
  • This nose has an upper side, which connects continuously and thus continuously to the curved contact surface and serves as an outer inclined to the skull contact surface for the line. If several lugs are present, then the line can be led out of the base part on an optimized side, without the base part having to be brought into a different rotational position for this purpose.
  • This embodiment can also be used without a curved inner region, ie without an inner cone.
  • the fixing element has an external thread, which can be screwed into the wellbore.
  • this external thread is self-tapping.
  • the screwing in of the base part can be facilitated if there are several, in particular three, noses which are arranged equidistantly over the outer circumference of the base part.

L'invention concerne un dispositif d'ancrage destiné à ancrer un conducteur dans un trou percé dans un crâne, lequel dispositif présente une partie de base (2, 3, 4, 5) et un couvercle (1) fermant de manière étanche la partie de base. La partie de base dispose d'un élément de fixation (5) destiné à fixer la partie de base dans le trou percé et d'une ouverture de passage pour faire passer le conducteur du trou percé vers un côté extérieur du dispositif d'ancrage. Une surface de support (30, 22) destinée à supporter le conducteur s'étend entre le trou percé et le côté extérieur dans la partie de base. La surface de support est conçue incurvée dans une direction constante de sorte que le conducteur est guidé en direction constante et avec un rayon de courbure qui est égal ou supérieur à un rayon de courbure minimal prédéfini de l'intérieur du crâne vers le côté extérieur. Ce dispositif d'ancrage permet de faire sortir à un angle plat un conducteur du trou percé dans un crâne sans que le conducteur soit fortement incurvé ou même plié.
