Abstract

In the dilation device, the dowel (3) is pressed for dilating the tissue through stretching of the elastomeric part (1) made from silicone, latex or polyurethane (PU). A tip is connected at front side of the elastomeric part and the cylindrical part is connected at rear side of the elastomeric part. The elastomeric part possesses an axial hole and is used as covering around the dowel that possesses laterally arranged grips that are fastened to a sheath. The dowel spread has a dowel with an axial hole. The dowel contains strips with different cross-sections. The piston possesses axially arranged grooves. The strips glide on to the grooves of the piston and are connected with a massively reshaped, non-extending tip. The piston has ergonomically arranged grip joined with a dilatable cylinder to extend the elastomeric part. The grip possesses a centrically arranged slit at its end.

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. Das Neue daran ist, daß das Gewebe um die Punktionsstelle herum, durch die Expansion eines Elastomerformteiles (1), durch einen Kolben (2), 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 invention (device) (FIG. 1 ) eliminates these disadvantages. The novelty is that the tissue around the puncture site, by the expansion of an elastomeric molded part ( 1 ), by a piston ( 2 ). 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.
