Abstract
Ein laparoskopischer Port (1) mit einem in eine erweiterte Öffnung der Bauchwand (10) einsetzbaren Rohrstück (3) von zum Offenhalten der Öffnung ausreichender Eigensteifigkeit, das in seiner Länge verstellbar ausgebildet ist, ist dadurch gekennzeichnet, dass das Rohstück (3) aus einem schraubenförmig gewickelten, geschlossenen Schlauch (4) aus wenigstens in Richtung der Achse (A) des Rohrstückes (3) querschnittserweiterbarem Material besteht, wobei der Schlauch (4) an eine Quelle eines Druckmediums angeschlossen ist.A laparoscopic port (1) with a tube piece (3) which can be inserted into an enlarged opening of the abdominal wall (10) and which is sufficiently rigid to hold the opening open, is adjustable in its length, characterized in that the blank (3) consists of a helically wound, closed tube (4) consists of at least in the direction of the axis (A) of the pipe section (3) querschnittserweiterbarem material, wherein the hose (4) is connected to a source of a pressure medium.
Description
Die Erfindung betrifft einen laparoskopischen Port nach dem Oberbegriff des Anspruches 1.The The invention relates to a laparoscopic port according to the preamble of claim 1.
Laparoskopische Ports ausreichender Eigensteifigkeit werden in eine Öffnung der Bauchwand eingesetzt, nachdem diese elastisch erweitert ist, um sie für das Durchführen von Instrumenten in den Bauchraum offen zu halten. Die Öffnung verschließende Ventile sorgen dafür, dass auch bei eingeführten Instrumenten die Öffnung gasdicht verschlossen bleibt.laparoscopic Ports of sufficient rigidity will be in an opening the abdominal wall inserted after it is elastically dilated, around them for performing instruments in keep the abdominal space open. The opening occlusive Valves ensure that even when imported Instruments the opening remains gas-tight.
Solche Ports sind mit engen Rohrstücken größerer Länge bekannt, durch die nur ein einzelnes, dünnes Instrument einführbar ist. Ports größeren Durchmessers sind zum gleichzeitigen Einführen mehrerer Instrumente geeignet oder zum Einführen einer Hand des Operateurs in den Bauchraum.Such Ports are larger with narrow lengths of pipe Length known by only a single, thin Instrument is insertable. Larger diameter ports are for simultaneously introducing multiple instruments suitable or for introducing a hand of the surgeon in the abdominal area.
Konstruktionen,
wie beispielsweise gemäß
Ein Port mit einem Rohrstück vorgegebener Länge passt optimal nur zu einer Bauchwand bestimmter Dicke. Ist die Bauchwand wesentlich dünner, so steht das Rohrstück störend weit in den Bauchwand hinein. Ist die Bauchwand wesentlich dicker, so reicht das Rohrstück in seiner Länge nicht aus, um die zuquellenden Fettschichten der Bauchwand offen zu halten.One Port with a piece of pipe of predetermined length fits optimal only to a stomach wall of a certain thickness. Is the abdominal wall much thinner, so the pipe piece is disturbing far into the abdominal wall. Is the abdominal wall much thicker, so the pipe section is not sufficient in its length, to keep the swollen fat layers of the abdominal wall open.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen laparoskopischen Port zu schaffen, der einfach und sicher verwendbar ist.The Object of the present invention is a laparoscopic To create port that is easy and safe to use.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst.These The object is achieved with the features of claim 1.
Erfindungsgemäss besteht das Rohrstück aus einem schraubenförmig gewickelten Schlauch, der mithilfe eines einführbaren Druckmediums im Schlauchquerschnitt verstellbar ist. Dadurch verändert sich die Länge des aus diesem Schlauch gebildeten Rohrstückes. Durch Veränderung des Innendruckes des Schlauches lässt sich die Länge sehr einfach einstellen. Sie kann z. B. auch während der Operation verstellt werden. Die Oberflächen der Konstruktion lassen sich relativ weich und verrundet und somit verletzungssicher ausbilden.According to the invention the pipe section consists of a helical wound tubing using an insertable pressure medium is adjustable in the tube cross-section. This changed the length of the pipe section formed from this hose. By changing the internal pressure of the hose leaves the length is very easy to adjust. You can z. B. also be adjusted during the operation. The surfaces The construction can be relatively soft and rounded and thus train injury-resistant.
Der Schlauch kann mit ausreichender Eigensteifigkeit ausgebildet sein, so dass er zwar noch unter höherem Druck querschnittserweiterbar ist, aber dennoch die Öffnung der Bauchwand mit ausreichender Kraft aussteift. Vorteilhaft ist der Schlauch jedoch gemäß Anspruch 2 mit einem Federdraht verstärkt. Dieser kann dem Schlauch im Wesentlichen die aussteifende Wirkung verleihen, wobei der Schlauch selbst hoch elastisch ausgebildet sein kann, um leicht verlängert werden zu können.Of the Hose can be designed with sufficient inherent rigidity, so that he still cross-sectionerable under higher pressure is, but still the opening of the abdominal wall with sufficient Power stiffening. However, the hose is advantageous according to the claim 2 reinforced with a spring wire. This can be the hose essentially give the stiffening effect, the hose itself can be highly elastic, slightly elongated to be able to.
Vorteilhaft, gemäß Anspruch 3, ist das Rohrstück zum distalen Ende hin kegelstumpfförmig verjüngt. Dadurch lässt es sich einfacher in die aufzuweitende Körperöffnung einführen.Advantageous, according to claim 3, the pipe section to the distal end tapered frustoconically. This makes it easier in the dilated body opening introduce.
In den Zeichnungen ist die Erfindung beispielsweise und schematisch dargestellt.In In the drawings, the invention is for example and schematically shown.
