Description
Bougie oder Katheter. Ein Bougie findet seinen Weg durch Verengungen der Harnröhre oder des Gebärmutterkanals, des Darmes, der Speiseröhre usw. am leichtesten, wenn das Einführungsende außerhalb der Mittelachse liegt, da die Eintrittsöffnung der Verengungen fast stets exzentrisch im Verlauf des Kanals liegen. Liegen mehrere Verengungen speziell bei der Harnröhre hintereinander und befinden sich taschenförmige Aufweitungen zwischen den Verengungen, was meistens der Fall ist, so werden diese verschiedenen, exzentrisch gelegenen Verengungseintrittsöffnungen bei einer Behandlung am besten passiert, wenn der nachfolgende Teil der außerhalb der Mittelachse gelegenen Spitze nach der Art von Korkenzieherwindungen gestaltet ist. Eine gleichzeitige Erweiterung der Verengung wird in kontinuierlicher Weise erzielt, wenn die Querschnitte solcher Windungen nach der Einführungsspitze zu gleichmäßig abnehmen.Bougie or catheter. A bougie finds its way through constrictions the urethra or uterine canal, intestines, esophagus, etc. easiest, when the insertion end is off the central axis, as the entry opening of the constrictions are almost always eccentric in the course of the canal. There are several Narrowings especially in the urethra one behind the other and are pocket-shaped There will be widenings between the constrictions, which is usually the case different, eccentrically located constriction entry openings during one treatment best happens when the trailing part of the off-center axis Tip is designed in the manner of corkscrew coils. A simultaneous Expansion of the constriction is achieved in a continuous manner when the cross-sections such turns after the insertion tip to decrease evenly.
Der Erfindungsgegenstand erfüllt diese Aufgaben zweckmäßig.The subject matter of the invention expediently fulfills these tasks.
Die Zeichnung .zeigt eine Seitendarstellung. An einem blattförmigen Griff a befindet sich. eine Stange b, die massiv als Bougie - hohl als Katheter - anzusehen ist. Am andern Ende der Stange befindet sich der Ansatz c, der abgerundete, korkenzieherähnliche Windurigen hat, die sich nach dem Einführungsende zu gleichmäßig verjüngen. Die Spitze des Instrumentes läuft abgestumpft außerhalb der Mittelachse aus. Infolge dieser Gestaltung wird das Instrument leicht unter ständigen Drehungen bis in die Blase eingeführt.The drawing shows a side view. On a leaf-shaped Handle a is located. a rod b, which is massive as a bougie - hollow as a catheter - is to be seen. At the other end of the rod is the approach c, the rounded, Has corkscrew-like Windurigen, which after the end of the introduction too evenly rejuvenate. The tip of the instrument is blunted off the central axis the end. As a result of this design, the instrument becomes easy with constant rotations inserted into the bladder.
