Abstract

Vorrichtung zur Entfernung von Gewebe, Flüssigkeiten oder anderen Materialien durch Absaugen.Device for removing tissue, liquids or other materials by suction.

Description

Die vorliegende Erfindung betrifft einen aus einer Formgedächtnislegierung bestehenden chirurgischen SaugerThe present invention relates to a surgical teat made of a shape memory alloy

Während chirurgischer Operationen werden meist starre metallische Sauger zur Entfernung von Flüssigkeiten, Knochenspänen oder Weichteilgewebe eingesetzt. Insbesondere bei der Entfernung von Hirntumoren durch die Nase muss der Sauger bis zum Zielgebiet entlang eines sehr kurvenreichen und verzweigten Weges geführt werden. Diese Operationstechnik erfordert einen großen Erfahrungsschatz der Operateure. Anatomische Risikostrukturen, wie die Hauptschlagader oder der Sehnerv, befinden sich direkt im Operationsgebiet und dürfen nicht verletzt werden. Aufgrund der verwendeten starren chirurgischen Instrumente entlang des kurvenreichen Operationskanals bis zum Hirntumor muss derzeit großflächig gesundes Gewebe und Knochenstruktur entfernt werden. Dies birgt Gefahren der Verletzung von Sehnerv oder der Hauptschlagader.During surgical procedures, rigid metallic suction cups are usually used to remove fluids, bone chips, or soft tissue. Especially in the removal of brain tumors through the nose of the nipple must be led to the target area along a very winding and branched way. This surgical technique requires a lot of experience of the surgeons. Anatomical risk structures, such as the main artery or the optic nerve, are located directly in the operating area and must not be injured. Due to the rigid surgical instruments used along the tortuous surgical canal to the brain tumor, it is currently necessary to remove healthy tissue and bone structure over a large area. This carries risks of injury to optic nerve or the main artery.

Zu den Vertretern der starren chirurgischen Sauger gehören beispielweise ”vedena® Saugrohr MV105-020” von medical highlights [1], ”Atraumatic Micro Suction Cannulas” von Aesculap [2], ”Micro Suction Cannula” von NEUROMEDEX [3] sowie ”Frazier Suction Cannula” von pfm medical [4].The representatives of the rigid surgical suction include, for example "® Vedena suction pipe MV105-020" of medical highlights [1], "Atraumatic Micro Suction cannulas" by Aesculap [2], "Micro Suction Cannula" Neuromedex of [3] and "Frazier Suction Cannula "by pfm medical [4].

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen chirurgischen metallischen Sauger zu entwickeln, mit dessen Hilfe die beschriebenen Nachteile vermieden werden.The present invention has for its object to develop a surgical metallic nipple, by means of which the disadvantages described are avoided.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine technische Vorrichtung nach Anspruch 1.This object is achieved by a technical device according to claim 1.

Die Erfindung ist ein chirurgischer Sauger, dessen Saugrohr aus einer Formgedächtnislegierung wie Nickel-Titan besteht. Damit wird es dem Operateur ermöglicht, das Saugrohr im geraden Ausgangszustand ( ) manuell zu verbiegen, um es entsprechend der Patientenanatomie anzupassen. Die Form darf sich direkt nach dem Biegevorgang nicht selbstständig verändern. Wenn es erforderlich ist, kann dieser Vorgang während der Operation mehrfach wiederholt werden. Die patientenspezifische Biegung erleichtert dem Operateur den Zugang zum Zielgebiet, das sich hinter anatomischen Hindernissen oder Abzweigungen befindet ( ). Nach der Operation wird der chirurgische Sauger in einem Autoklaven sterilisiert. Durch den Wärmeeintrag wird das gebogene Saugrohr wieder automatisch in den geraden Ausgangszustand versetzt und kann erneut für die Operation verwendet werden ( ). Das Formgedächtnis-Saugrohr ist mit einem ergonomischen Handstück verbunden, das aus einem anderen Material wie Metall oder Kunststoff besteht. Ein konventioneller Absaugschlauch wird am Ende des Handstückes werkzeuglos befestigt und mit einer Absaugpumpe verbunden. Die Erfindung soll dazu beitragen, die Operation minimalinvasiver durchzuführen. Aufgrund der patienten-spezifischen Anpassung muss weniger gesundes Gewebe und Knochen großflächig entfernt werden, um zum Zielgebiet zu gelangen. Anstatt mehrere starre Sauger mit verschieden gebogenen Saugrohren zu verwenden, ist nur noch ein Sauger erforderlich.The invention is a surgical nipple whose suction tube is made of a shape memory alloy such as nickel-titanium. This makes it possible for the surgeon, the suction tube in the straight initial state ( ) to manually adjust it to fit the patient's anatomy. The shape must not change automatically after the bending process. If necessary, this operation can be repeated several times during the operation. The patient-specific bend facilitates access to the target area behind anatomical obstacles or branches ( ). After surgery, the surgical teat is sterilized in an autoclave. Due to the heat input, the bent suction tube is automatically returned to the straight starting state and can be used again for the operation ( ). The shape memory suction tube is connected to an ergonomic handpiece made of a different material, such as metal or plastic. A conventional suction hose is attached to the end of the handpiece without tools and connected to a suction pump. The invention is intended to help carry out the operation with minimal invasiveness. Due to the patient-specific adaptation, less healthy tissue and bone must be removed over a large area in order to reach the target area. Instead of using several rigid suction cups with differently bent suction tubes, only one suction device is required.
