KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Operationen mit schneidenden Werkzeugen in eiterigen Wundhöhlen oder an solchen Körperstellen, bei denen die Operation starken Bluterguß zur Folge hat, stören die Überschwemmungen des Operationsfeldes mit Blut, Eiter usw. die Arbeit des Chirurgen außerordentlich. Vorliegende Erfindung löst die Aufgabe der Beseitigung aller dieser das Operieren störenden Flüssigkeiten dadurch,During operations with cutting tools in or on purulent wound cavities Parts of the body where the operation has resulted in severe bruising are annoying Flooding the surgical field with blood, pus, etc. the surgeon's job extraordinary. The present invention solves the problem of eliminating all of these Operate on interfering fluids by
ίο daß ein mit Druckwasser oder Druckluft betriebenes Gebläse zur Erzeugung einer dem Bedürfnis entsprechenden Luftdruckdifferenz benutzt und diese Luftdruckdifferenz als Druckluft auf die zu operierende Stelle einwirken gelassen wird.ίο that a pressurized water or compressed air operated Blower used to generate an air pressure difference corresponding to the need and this air pressure difference as Compressed air is allowed to act on the area to be operated on.
In der Zeichnung sind in beispielsweiser Ausführung mehrere Operationsmesser mit verschiedener Anordnung der Druckluftleitung dargestellt.In the drawing, several surgical knives with different ones are shown as an example Arrangement of the compressed air line shown.
ao Fig. ι zeigt ein der Länge nach durchbohrtes Messer a. Es bezeichnen ferner b die Bohrung, c die kleine runde oder schlitzartige Öffnung in der Nähe der Schneide, d eine Tülle zum Anschließen der Rohr- oder Schlauchleitung, die die Druckdifferenz zum Operationswerkzeug übermittelt. Die Drucköffnung c kann auch in größerer Anzahl vorgesehen werden.ao Fig. ι shows a lengthwise pierced knife a. It also denotes b the bore, c the small round or slit-like opening near the cutting edge, d a grommet for connecting the pipe or hose that transmits the pressure difference to the surgical tool. The pressure opening c can also be provided in larger numbers.
Fig. 2 stellt ein Messer mit durchbohrtem Griff β dar. Bei f wird ein besonders geformtes Ansatzstück g beispielsweise mittels Einsteckens befestigt, zum Zweck, verschiedenartige Mündungen der Druckluftleitung an die Schneide des Operationswerkzeuges führen zu können.Fig. 2 shows a knife with a pierced handle β . At f , a specially shaped extension piece g is attached, for example by means of insertion, for the purpose of being able to lead various openings of the compressed air line to the cutting edge of the surgical tool.
Fig. 3 gibt ein Messer mit Führungsrohr h wieder, in dem das Druckluftrohr i verschiebbar ist, um es an einer bestimmten Stelle der Schneide einstellen zu können.3 shows a knife with a guide tube h in which the compressed air tube i can be displaced in order to be able to set it at a certain point on the cutting edge.
Fig. 4 zeigt ein Ausführungsbeispiel für eine leicht lösbare Verbindung zwischen Messer a und Druckluftrohr i, indem ein konischer Stift k auf dem Rücken des Messers angeordnet ist. Auf diesen Stift kann das Druckluftrohr mittels eines an ihm angeordneten kurzen Rohrstutzens / aufgesteckt werden. Die leichte Lösbarkeit von Messer und Druckluftrohr hat den Vorteil, daß jedes der beiden Werkzeuge auch getrennt gehandhabt werden kann, beispielsweise wenn der Assistent des Arztes das Druckluftrohr bedient.Fig. 4 shows an embodiment for an easily detachable connection between knife a and compressed air pipe i, in that a conical pin k is arranged on the back of the knife. The compressed air pipe can be plugged onto this pin by means of a short pipe socket /. The fact that the knife and compressed air tube can be easily detached has the advantage that each of the two tools can also be handled separately, for example when the doctor's assistant operates the compressed air tube.
