Description
Probeexcisionsgerät Die Erfindung betrifft ein Probeexcisionsgerät zur Anwendung der Saugbiopsie bei Probeexcisionen aus dem Rektum oder anderen Körperhöhlen.Trial excision device The invention relates to a trial excision device for the use of suction biopsy for sample excisions from the rectum or other body cavities.
Zur Entnahme von Schleimhautgewebe aus dem Rektum oder anderen Körperhöhlen sind Probeexcisionszangen bekannt, bei denen das erforderliche Material mittels zweier Zangenbacken - von denen eine als Stempel und die andere als Matrize ausgebildet ist - ausgestanzt wird. Die Größe der Materialprobe wird dabei von den Dimensionen der Zangenbacken bestimmt. For removing mucosal tissue from the rectum or other body cavities are trial excision forceps known in which the required material by means of two pliers jaws - one designed as a punch and the other as a die is - is punched out. The size of the material sample depends on the dimensions the jaws determined.
Weiterhin ist ein Probeexcisionsgerät bekannt, das aus einem Hohlzylinder und aus einem darin mechanisch bei gleichwertiger Rotationsbewegung auf und ab beweglichen ringförmigen Messer besteht. Bei diesem Gerät wird ein kleines Stück Schleimhaut durch ein seitliches Loch im Hohlzylinder gesogen und durch das rotierend nach vorn bewegte Messer abgestanzt. Die Größe der Materialprobe ist dabei abhängig von den Dimensionen des seitlichen Loches im Hohlzylinder und vom jeweils angewandten Sog bzw. Unterdruck, wobei letzterer in erster Linie auf die Tiefe der Materialprobe Einfluß nimmt. Furthermore, a trial excision device is known, which consists of a hollow cylinder and from one that can be moved up and down mechanically with equivalent rotational movement ring-shaped knife. This device uses a small piece of mucous membrane sucked through a side hole in the hollow cylinder and rotating forward through it moving knife punched. The size of the material sample depends on the Dimensions of the side hole in the hollow cylinder and the suction applied in each case or negative pressure, the latter primarily due to the depth of the material sample Influence.
Die bekannten Instrumente haben den Nachteil, daß die Dimensionen des Probegewebes bei der Probeexcisionszange überhaupt nicht und bei dem bekannten Probeexcisionsgerät nur unter Einflußnahme auf die Tiefe der Entnahme variiert werden können. The known instruments have the disadvantage that the dimensions of the sample tissue not at all with the trial excision forceps and with the known The specimen excision device can only be varied by influencing the depth of the removal can.
Der Erfindung liegt dem Bekannten gegenüber die Aufgabe zugrunde, die Möglichkeit zur Entnahme verschieden großer Gewebestücke bei gleichbleibender Probetiefe zu schaffen. The invention is based on the task of the known the possibility of removing different sized pieces of tissue while maintaining the same To create trial depth.
Diese Aufgabe wird im wesentlichen erfindungsgemäß dadurch gelöst, daß das seitliche Langloch durch eine Blende einstellbar gestaltet ist. This object is essentially achieved according to the invention by that the lateral elongated hole is designed to be adjustable by a diaphragm.
Nachstehend wird ein Ausführungsbeispiel des Erfindungsgegenstandes an Hand einer Zeichnung näher erläutert. Es zeigt Abb. 1 das Gesamtgerät im Aufriß, Abb. 2 das Oberstück des Gerätes im Schnitt, Abb. 3 den distalen zylindrischen Teil des Gerätes im Schnitt. The following is an embodiment of the subject invention explained in more detail using a drawing. Fig. 1 shows the entire device in elevation, Fig. 2 the upper part of the device in section, Fig. 3 the distal cylindrical part of the device in section.
Das zylinderförmige Messer 1 ist mit einem Führungsrohr 2, durch das in radialer Richtung ein Stift 3 führt, verbunden und wird durch einen Druck auf den Knopf 4 zum Langloch 5 im Hohlzylinder 6 hinbewegt. Eine Feder 7 führt bei nachlassendem Druck auf den Knopf 4 das Messer 1 in seine Ausgangsstellung zurück. Der Stift 3 im Führungsrohr 2 gleitet in einer wendelförmigen Nut 8 und gibt so dem Messer 1 eine rotierende Bewegung. Das zylin- derförmige Messer 1 ist gleitend in den Hohlzylinder 6 eingepaßt und deshalb mit zwei schrägverlaufenden Bohrungen 9 versehen, die eine einwandfreie Sogwirkung - ausgehend vom Stutzen 10 - am Langloch5 gewährleisten. Das seitliche Langloch 5 im Hohlzylinder 6 ist durch eine auf dem Hohlzylinder 6 sitzende und vorzugsweise mit zwei seitlich gegenüberliegenden Laschen 12 versehene verschiebbare Blende 11 auf die gewünschte Größe einstellbar. Der Instrumentenschaft 16 ist in einem Halter 13 drehbar gelagert und wird mittels Kordelmutter 14 in der gewünschten Stellung arretiert. Der Handgriff 15 ist verstellbar am Halter 13 befestigt. The cylindrical knife 1 is with a guide tube 2 through which leads a pin 3 in the radial direction, connected and is pressed by a pressure on the button 4 towards the elongated hole 5 in the hollow cylinder 6. A spring 7 leads to When the pressure on the button 4 decreases, the knife 1 returns to its original position. The pin 3 in the guide tube 2 slides in a helical groove 8 and is so the knife 1 a rotating movement. The cylindrical the shaped knife 1 is sliding fitted into the hollow cylinder 6 and therefore with two inclined bores 9 provided that a perfect suction effect - starting from the nozzle 10 - at the elongated hole5 guarantee. The side slot 5 in the hollow cylinder 6 is through a on the Hollow cylinder 6 seated and preferably with two laterally opposite tabs 12 provided displaceable diaphragm 11 adjustable to the desired size. The instrument shaft 16 is rotatably mounted in a holder 13 and is tightened by means of a cord nut 14 in the locked in the desired position. The handle 15 is adjustably attached to the holder 13.
