Description
Vorrichtung an !TrokarenDevice on! Trocars
Die bekannten Erokare, die sich auch susi Einführen von Endoskopen in die Bauch- oder Brusthöhle eignen, weisen entsprechend dem Querschnitt des Endoskopes einen verhältnismäßig engen Durchgang auf, der sum Einführen des Endoskopes ausreichte.The known Erokare, which are also suitable for inserting endoscopes into the abdominal or thoracic cavity, have a relatively narrow passage corresponding to the cross section of the endoscope, which is sufficient for inserting the endoscope.
Der Sinfiüirungs schaft neuerer Endoskope ist nun aus technischen Gründen im Querschnitt stärker ausgebildet, sumal die Endoskope auch für Photographie und Kinematographie eingerichtet sind. Damit ist es erforderlich, auch den Durchgang der !ürokare stärker auszubilden. Diese Entwicklung hat aber zur folge, daß ältere Endoskope wegen ihres schwächeren Schaftes nicht mehr abgedichtet eingeführt werden können.The sympathy of newer endoscopes is now out of technical Reasons more developed in cross-section, including endoscopes for photography and cinematography are set up. So it is necessary, also the To train passage of the! Ürokare more strongly. This development but has the consequence that older endoscopes are no longer introduced in a sealed manner because of their weaker shaft can be.
Der !Teuerung liegt die Aufgahe zu G-runde, eine Torrichtung su schaffen, die es ermöglicht, die älteren Endoskope auch in die neueren !Trokare mit ihrem größeren Durchgang abgedichtet einführen su können,The rise in prices is the task of G-round, one gate direction su create, which makes it possible to use the older endoscopes also in the newer ones! Trocars with their larger ones Sealed passage can be introduced,
Die neue Yorrichtung besteht aus einem Zwischenstück, in das ein Endoskop luftdicht einführbar ist, das im Querschnitt schwächer ist als der Trokardorn« Dies geschieht in zweckmäßiger Weise dadureh, daß das Zwischenstück aus einem mit einer Dichtführung versehenen Zopf und einem rohrförmigen Schaft besteht, dessen Außendurchmesser etwa dem des Srokardornes bzw. dem Durchgang der Dichtführung im Mihrungskopf des Irokars entspricht« Dabei entspricht auch der Durchgang der Dichtführung und der Innendurchmesser des Schaftes des Zwischenstückes dem Außendurchmesser des Sndoskoprohres.The new device consists of an intermediate piece, into which an endoscope can be inserted in an airtight manner, which is weaker in cross section than the trocar pin «This happens in an expedient manner that the intermediate piece consists of a pigtail provided with a sealing guide and a tubular shaft, the outer diameter of which is approximately that of the srocard or the passage of the Sealing guide in the miter head of the Irokar corresponds to " The passage also corresponds to the sealing guide and the inner diameter of the shaft of the intermediate piece is the outer diameter of the endoscope tube.
Die Yorrichtung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispieles erläutert. Ss aeigen in schaubildlicher Darstellungsweise, teilweise geschnitten The Yorrichtung is explained with reference to an embodiment shown in the drawing. Ss aeigen in diagrammatic representation, partially cut

Im dargestellten Ausführungsbeispiel ist mit 3 der !Erokar bezeichnet, der aus einem Schaft 4, einem Yentilkopf 5 und einem Mhrungskopf 6 besteht, dessen Diehtführung den eingeführten Trokardorn gegenüber dem Schaft 4 abdichtet* In the illustrated embodiment, 3 is the! Erokar denotes, which consists of a shaft 4, a Yentilkopf 5 and a Mhrungskopf 6, whose Diehtführung seals the inserted trocar against shaft 4 *

Beim Auswechseln des !Erokardornes 8 gegen ein Endoskoprohr 9 älterer Bauart mit schwächerem. Eohrquerschnitt wird das Zwischenstück 10 mit seinem Schaft 11 verwendet, der von einem Kopf 12 mit einer Dichtführung 13 ausgeht. Der Schafft 11 hat den gleichen Querschnitt wie der (Drokardorn 8, jedoch hat die Dichtführung 13 des Zwischenstückes 10 einen Durchgang, der dem schwächeren Querschnitt des Bndoskoprohres 9 entspricht, so daß das eingeführte Endoskoprohr 9 gegenüber dem Schaft 4 des !Erokars abgedichtet ist*When replacing the! Erocard mandrel 8 for an endoscope tube 9 older design with weaker. Ear cross section the intermediate piece 10 is used with its shaft 11, which starts from a head 12 with a sealing guide 13. The shaft 11 has the same cross-section as the (Drokardorn 8, however, the sealing guide 13 of the intermediate piece 10 has a passage that has the weaker cross section of the Bndoskoprohres 9 corresponds, so that the imported Endoscope tube 9 opposite the shaft 4 of the! Erokar is sealed *
