Abstract

The apparatus has a handle (2) for the user to hold. An elastomer member (1) is fastened e.g. by adhesive to the cylindrical flange of the handle. A piston (3) is pressed by the handle causing the elastomer member to expand which causes dilation of the tissue.

Description

Stand der Technik sind Vorrichtungen für die percutane Tracheotomie, bei der die Punktionsstelle in der Trachea zum Einführen der Tracheakanüle durch Schrauben (Fa. Rüsch), oder mit konisch zulaufendem Dilationsstab (Fa. Cook, Fa. Portex), oder mit retrograder Dilationstechnik (Fa. Tyco) dilatiert wird. Nachteile dieser Methoden sind Schädigung des Gewebes, Verletzung der Luftröhrenhinterwand und Schwierigkeiten bei der Dilation.was standing The technology is devices for the percutaneous tracheostomy, in which the puncture site in the trachea for insertion the tracheal cannula through Screws (Rüsch), or with a tapered dilation rod (Cook, Fa. Portex), or dilated with retrograde dilation technique (Tyco). Disadvantages of these methods are damage to the tissue, injury the tracheal posterior wall and Difficulty in Dilation.

Die hier dargestellte Erfindung (Vorrichtung) (1) beseitigt diese Nachteile.The invention (device) (FIG. 1 ) eliminates these disadvantages.

Das Neue daran ist, daß das Gewebe um die Punktionsstelle herum, durch die Expansion eines Elastomerformteiles (1), durch einen Kolben (3), gewährleistet wird. Dadurch erfolgt eine schonende Dehnung des Gewebes, eine Verletzung der Tracheahinterwand ist, da der Dilator nicht weit vorgeschoben werden muß, unmöglich. Außerdem ist eine ausreichende Dilation in jedem Fall gewährleistet.The novelty is that the tissue around the puncture site, by the expansion of an elastomeric molded part ( 1 ), by a piston ( 3 ). This results in a gentle stretching of the tissue, a violation of the Tracheah inner wall is impossible, since the dilator does not have to be advanced far. In addition, sufficient dilation is guaranteed in any case.
