Abstract

The system of indicating the position of diseased structure in the human body uses a hollow needle in the end of which an indicator element (1) is mounted. A wire (4) is attached to the indicating element and runs up through the needle. The indicating element is in the form of a short tube section which is mounted inside the end of the needle. The needle and element are bevelled forming a sharp point to facilitate the needle being pushed into the body. When the section is near the diseased part, it is pushed out of the needle by a third tube section (3) which also fits inside the needle. It is hooked behind the diseased section while the needle is withdrawn. A knot is tied in the wire just outside the body.

Description

Die Vorrichtung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The device relates to a device according to the preamble of claim 1.

Derzeit werden eine Reihe von Lokalisierungselementen für perkutane Markierungen von Tumoren und anderen anatomischen Strukturen angeboten. Alle diese Elemente haben drahtartige Verbindungsteile, die nach der Markierung außen aus dem Körper hervorstehen. Dadurch wird ein Abdecken des herausstehenden Endes schwierig und der Transport des Patienten in den Operationssaal muß meist unmittelbar erfolgen. Ein Verrutschen des Lokalisationselementes ist die Gefahr.A number of localization elements are currently being used for percutaneous labeling of tumors and other anatomical structures. All of these elements are wire-like Connecting parts that protrude from the outside of the body after marking. This will make a Covering the protruding end difficult and transporting the patient into the The operating room must usually be done immediately. The localization element slips Danger.

Die Erfindung hat das Ziel, dieses Problem zu lösen.The object of the invention is to solve this problem.

Die Erfindung ist in den folgenden Figuren dargestellt:The invention is illustrated in the following figures:

Fig. 1 Querschnitt durch ein distales Ende der Lokalisierungsvorrichtung, Fig. 1 cross section through a distal end of the locating device,

Fig. 2 Ablauf der Lokalisation, Fig. 2 expiry of localization,

Fig. 3 vergrößerte Darstellung des distalen Endes der Lokalisationsvorrichtung von Fig. 2. Fig. 3 are enlarged view of the distal end of the localization device of FIG. 2.

Fig. 1 zeigt die erfinderische Vorrichtung im Querschnitt des distalen Endes. In der Hohlnadel 2 befindet sich das Lokalisationselement. Am Lokalisationselement ist ein Lokalisationsfaden angebracht, der in proximaler Richtung durch ein Antriebsröhrchen hindurch verläuft. Fig. 2 zeigt die Anwendung in 6 Schritten:
 Fig. 1 shows the inventive device in cross section of the distal end. The localization element is located in the hollow needle 2 . A localization thread is attached to the localization element and runs through a drive tube in the proximal direction. Fig. 2 shows the application in 6 steps:

  • a) die Vorrichtung wird seitlich an der Läsion positionierta) the device is positioned laterally on the lesion
  • b) durch Vorschieben des Antriebsröhrchens oder Zurückziehen der Hohlnadel gelangt das Lokalisationselement in das freie Gewebeb) by pushing the drive tube or pulling back the hollow needle Localization element in the free tissue
  • c, d, e) durch Zurückziehen der Hohlnadel und des Antriebsröhrchens sowie durch Zurückziehen des Fadens 4 dreht sich das Lokalisationselement aus der axialen Richtung radial herausc, d, e) by pulling back the hollow needle and the drive tube and pulling back the thread 4 , the localization element rotates radially out of the axial direction
  • f) nach vollständigem Entfernen des Antriebsröhrchens und der Hohlnadel liegt das Lokalisationselement senkrecht zur Läsion frei. Nun kann der Faden extrakorporal verknotet werden, so daß dieser in einer gewissen Spannung zwischen dem Lokalisationselement und dem Knoten fest im Gewebe positioniert ist.f) after complete removal of the drive tube and the hollow needle that lies Localization element perpendicular to the lesion free. Now the thread can be knotted extracorporeally be so that this in a certain tension between the localization element and the knot is firmly positioned in the tissue.

Fig. 3 zeigt den distalen Teil der Vorrichtung der Fig. 2c in vergrößerter Darstellung. Fig. 3 shows the distal part of the device of Fig. 2c in an enlarged view.

Verbindet man das Lokalisierungselement mit einem chirurgischen Faden oder einem feinen Stahldrahtgeflechtfaden, so kann das herausstehende Ende an die Haut angelegt und mit einem sterilen Pflaster abgedeckt werden. Der Eingriff ist ambulant bei Patienten durchführbar, die erst am nächsten oder sogar erst Tage später zur Operation kommen. Bei einem anderen Anwendungsfall, der Entfernung von kleinen tumorverdächtigen Arealen aus der Lunge, gibt es bisher nur wenige Versuche, Tumorlokalisationen mit den bestehenden Systemen durchzuführen, siehe z. B. den Artikel von Geaurceau "The required technique for localization of lungnodules during thoracoscopic resection" aus der Zeitschrift "Chest".If you connect the localization element with a surgical thread or a fine one Steel wire mesh thread, so the protruding end can be applied to the skin and with a sterile plasters. The procedure can be performed on an outpatient basis for patients who are only on come for surgery next or even days later. In another use case, The removal of small tumor-suspicious areas from the lungs has so far been few Attempts to carry out tumor localizations with the existing systems, see e.g. B. the article by Geaurceau "The required technique for localization of lungnodules during thoracoscopic resection "from the magazine" Chest ".

Diese Technik beinhaltet jedoch das Problem, daß der Draht bei Atmung verschieblich ist, d. h. aus der Brusthöhle hinein- und herausgeschoben wird und daß, wenn während der Operation die eine Lungenhälfte, in der sich der Lokalisierungshaken befindet, nicht mehr beatmet wird und zusammenfällt, der ganze Draht in den Brustraum hineinrutschen kann. Hier ist ebenfalls ein Lokalisierungshaken mit angebrachtem Faden dazu geeignet, über ein Reservoir entsprechend Faden freigeben zu können, um erstens die Atemverschieblichkeit zu kompensieren und zweitens beim Zusammenfallen der Lunge ein Verschwinden des Fadens zu verhindern. However, this technique involves the problem that the wire is displaceable when breathing, i.e. H. from the Breast cavity is pushed in and out and that if one during the operation Half of the lung in which the localization hook is located is no longer ventilated and collapses, the whole wire can slide into the chest. Here is also one Localization hook with attached thread suitable for this, via a reservoir corresponding thread to be able to release, firstly to compensate for breathability and secondly when The lungs collapse to prevent the thread from disappearing.
