Betr.: Endoscopisches Extraktionsinstrument Beschreibung Subject: Endoscopic Extraction Instrument Description
Endoscopisches Extraktionsgerät,Endoscopic extraction device,
insbesondere zur Aufnahme und Bergung von Gegenständen aus Körperhöhlen. especially for picking up and retrieving objects from body cavities.
In den Anwendungsgebieten der Laparoscopie ( hier exemplarisch für Endoscopische Anwendungsgebiete gewählt) - "eine technisch und anatomisch definierte Anwendungsform der Endoscopie" (s.Literaturnachweis ^stellt sich zur Zeit ein komplexer Problemkreis dar, welcher das Endoscopische Extraktionsgerät erforderlich macht und im weiteren am Beispiel der laparoscopischen Gallenblasenextraktion erläutert wird.(Laparoscopie = Bauchspiegelung)In the application areas of laparoscopy (here chosen as an example for endoscopy application areas) - "a technically and anatomically defined application form of endoscopy" (see references) a complex range of problems is currently emerging, which requires the endoscopic extraction device and is explained below using the example of laparoscopic gallbladder extraction. (Laparoscopy = laparoscopy)
Zur Zeit stellt sich das Problem, daß es noch keine befriedigende Lap. Verfahrensweise gibt, die Gallenblase aus der Bauchhöhle zu bergen.The problem at present is that there is still no satisfactory laparoscopic procedure for removing the gallbladder from the abdominal cavity.
Ist die Gallenblase aus dem Gallenblasenbett der Leber gelöst, wird sie im weiteren entwederOnce the gallbladder has been separated from the gallbladder bed of the liver, it is then either
- durch die Trokarhülse gezogen (,wenn sie hindurch paßt),- pulled through the trocar sleeve (if it fits through),
- durch eine extra eingeführte größere Trokarhülse gezogen oder- pulled through a specially inserted larger trocar sleeve or
- direkt durch die Bauchwand extrahiert - ohne Trokarhülse. Die Nachteile dieser Vorgehftsweisen sind:- extracted directly through the abdominal wall - without a trocar sleeve. The disadvantages of this procedure are:
- Entzündungen der Bauchdecke durch Kontamination mit Gallensäften.- Inflammation of the abdominal wall due to contamination with bile.
- Oftmals paßt die Gallenblase nicht durch die Trokarhülsen und macht zusätzliche Manipulationen notwendig, hieraus konkret resultieren:- Often the gallbladder does not fit through the trocar sleeves and requires additional manipulation, which specifically results in:
-Steinverlust in die freie Bauchhöhle.
-Zusätzliche Gewebeschädigung.
-Perforation der Gallenblase.
-Unnötig großer Hautschnitt.
-Zusätzlicher Zeitaufwand; Narkosedauer.-Loss of stones into the free abdominal cavity.
-Additional tissue damage.
-Perforation of the gallbladder.
-Unnecessarily large skin incision.
-Additional time required; duration of anesthesia.
- Die Luft entweicht nach Extraktion der Gallenblase aus der Bauchhöhle (Pneumoperitoneum), wenn die Gasabdichtung durch die Trokarhülse fehlt, der weitere Op-Verlauf ist wesentlich behindert.- The air escapes from the abdominal cavity after extraction of the gallbladder (pneumoperitoneum) if the gas seal provided by the trocar sleeve is missing, the further course of the operation is significantly hindered.

Dieser Problemkomplex wird mit dem Endoscopischen Extraktionsinstrument - für das in den Schutzansprüchen Schutz beantragt wird - gelöst.This complex of problems is solved with the endoscopic extraction instrument - for which protection is sought in the claims.
- Das Instrument wird im zusammengefalteten Zustand über eine Trokarhülse in die Bauchhöhle eingeführt, der Metallbügel spannt sich spontan in der freien Bauchhöhle auf und öffnet hierbei gleichzeitig den Beutel.- The instrument is inserted into the abdominal cavity in a folded state via a trocar sleeve, the metal bracket spontaneously stretches into the free abdominal cavity and at the same time opens the bag.
- Die mit der Fasszange gehaltene Gallenblase wird in den Beutel eingebracht, der Metallbügel zurückgezogen, so daß sich der Beutel wie von einer Schlinge (Metallbügel) zugezogen wird. Hierbei bildet die Trokarhülse das Widerlager. Die Gallenblase wird mit der Zange gefaßt und zusammen mit dem Extraktionsinstrument durch die Trokarhülse herausgezogen.- The gallbladder held with the forceps is inserted into the bag, the metal bracket is pulled back so that the bag is closed like a loop (metal bracket). The trocar sleeve forms the counterweight. The gallbladder is grasped with the forceps and pulled out together with the extraction instrument through the trocar sleeve.
Die Vorteile durch das neue Endoscopische Extraktionsinstrument sind:The advantages of the new endoscopic extraction instrument are:
1) Es ist keine Kontamination der Bauchdecke mehr möglich,deshalb sind Bauchwandentzündungen jetzt unmöglich.1) Contamination of the abdominal wall is no longer possible, so abdominal wall inflammation is now impossible.
2) Kein Gallenblasensteinverlust möglich.2) No loss of gallstones possible.
3) Bei perforierter Gallenblasenwand entleeren sich Sekret und Steine in den Beutel, es ist kein Kontakt mit Gewebe möglich.3) If the gallbladder wall is perforated, secretions and stones empty into the sac; contact with tissue is not possible.
Das Instrument ermöglicht weiterhin, daß die Gallenblase schon in der Bauchhöhle aufgeschnitten werden kann. Dies erfolgt in der Öffnung des Beutel. Das weitere Vorgehen erfolgt wie oben geschildert. Beim Zurückziehen durch die Trokarhülse wird die Gallenblase kompremiert, Flüssigkeit und Steine entweichen in den Beutel, damit nimmtThe instrument also allows the gallbladder to be cut open in the abdominal cavity. This is done in the opening of the bag. The further procedure is as described above. When pulled back through the trocar sleeve, the gallbladder is compressed, fluid and stones escape into the bag, so that
der Durchmesser der Gallenblase ab und diese paßt nun auch durch Trokarhülsen keineren Durchmessers.(Das Volumen der Gallenblase verteilt sich auf den Rauminhalt des Beutels, der Gesamtdurchmesser verkleinert sich.)the diameter of the gallbladder decreases and it now fits through trocar sleeves of any diameter. (The volume of the gallbladder is distributed over the volume of the bag, the total diameter decreases.)
Die weiteren Vorteile durch das Endoscopische Extraktionsinstrument sind:The other advantages of the endoscopic extraction instrument are:
4) Kleiner Hautschnitt bzw. dünnere Trokarhülsen.4) Small skin incision or thinner trocar sleeves.
5) Das Pneumoperitoneum bleibt erhalten.5) The pneumoperitoneum is maintained.
6) Auch große Gallenblasen, die primär nicht durch eine Trokarhülse passen, können laparoscopisch operiert werden.6) Even large gallbladders that do not initially fit through a trocar sleeve can be operated on laparoscopically.
7) Zeitersparnis, kürzere Narkosedauer. -7) Time saving, shorter anesthesia duration. -

Weist das Instrument, wie im Nebenanspruch beschrieben, am Ende des Beutels noch einen sich konisch erweiternden aufblasbaren Ballon auf, dieser wird durch den zuführenden Schlauch mit Kochsalzlösung gefüllt ( das in den Schlauch eingearbeitete Ventil entspricht den in Blasenkathetern üblichen Ventilen - vergl. hierzu: Norta-Katheter, No.9385 BDF-Beiersdorf AG Hamburg), ergeben sich weitere Vorteile.If the instrument, as described in the secondary claim, has a conically expanding inflatable balloon at the end of the bag, which is filled with saline solution through the supply tube (the valve incorporated in the tube corresponds to the valves commonly found in bladder catheters - see: Norta catheter, No.9385 BDF-Beiersdorf AG Hamburg), further advantages arise.
- Gallenblasen, die primär auch mit dem Endoscopischen Extraktionsinstrument nicht durch die Trokarhülsen passen, können durch dieses weiterentwickelte Extraktionsinstrument extrahiert werden, indem beim Zurückziehen des Instrumentes aus der Bauchhöhle die Trokarhülse ebenfalls zurückgezogen wird, wobei dann der aufgeblasene Ballon die Einstichstelle verschließt und das Pneumoperitoneum erhalten bleibt.- Gallbladders that initially do not fit through the trocar sleeves even with the endoscopic extraction instrument can be extracted using this advanced extraction instrument, by withdrawing the trocar sleeve when the instrument is withdrawn from the abdominal cavity, whereby the inflated balloon closes the puncture site and the pneumoperitoneum is maintained.
