Chirurgischer Fadenschneider, insbesondere für die Minimal Invasive TherapieSurgical thread cutter, especially for minimally invasive therapy

Zusammenfassung
LOSummary
LO

Die Erfindung betrifft ein Instrument, insbesondere für den Einsatz in der Minimal Invasiven Therapie (MIT), zum Schneiden von Fadenmaterial, wie es für intrakorporale Nähte verwendet wird.The invention relates to an instrument, in particular for use in minimally invasive therapy (MIT), for cutting thread material as used for intracorporeal sutures.

L5 Stand der TechnikL5 State of the art

Die Fortschritte der Technik in der MIT erlauben heute das Legen von intrakorporalen Nähten und haben damit die Entwicklung auf diesem Gebiet erheblich vorangebracht. Das zur Verfügung stehende Nahtmaterial, insbesondere der geflochtene und versteifte Faden aus Polyglykolsäure, ist nicht nur resorbierbar, sondern weist auch die erforderliche Festigkeit auf, wie sie für eine chirurgisch einwandfreie Naht gebraucht wird. Nachteilig ist, daß er mit den normalerweise für den Gewebeschnitt benutzten Präparier-Scheren nur schwer geschnitten werden kann, bzw. die Scheren verbiegen sich und klemmen den Faden ein.The technological advances in MIT now allow the placement of intracorporeal sutures and have thus significantly advanced development in this field. The suture material available, in particular the braided and stiffened thread made of polyglycolic acid, is not only resorbable, but also has the necessary strength required for a surgically perfect suture. The disadvantage is that it is difficult to cut with the dissecting scissors normally used for tissue cutting, or the scissors bend and pinch the thread.

Erfindunginvention

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, einen für das Schneiden des Fadens geeigneten chirurgischen Fadenschneider zur Verfügung zu stellen, der sich weder verbiegt, noch den Faden einklemmt. Benutzt wird hier das an sich bekannteThe present invention is based on the task of providing a surgical thread cutter suitable for cutting the thread, which neither bends nor pinches the thread. The known

S5 Prinzip einer scharfen Klinge, die gegen einen geschlitzten, aber stumpfen Amboß arbeitet. Der Schlitz ist dabei so gestaltet, da/3 er gerade passend die scharfe Klinge der Schneide aufnimmt und so den gegen den Amboß gepreßten Faden durchtrennt. Die Klinge ist dabei schräg geschnitten und führt damit beim Schneiden eine Relativbewegung gegen den Amboß aus, was denS5 Principle of a sharp blade that works against a slotted, but blunt anvil. The slot is designed in such a way that it fits the sharp edge of the cutting edge just right and thus cuts through the thread pressed against the anvil. The blade is cut at an angle and thus performs a relative movement against the anvil when cutting, which

Schneidevorgang erheblich'erleichfcört*.* In '&itfe£ besonderen Ausführungsform der Erfindung ist der Amboß bogenförmig gekrümmt, um damit eine sichere Aufnahme und einen sicheren Halt des Fadens während des Schneidevorgangs zu erleichtern. 5Cutting process is made considerably easier.* In a particular embodiment of the invention, the anvil is curved in an arc to facilitate secure reception and secure holding of the thread during the cutting process. 5

Zusätzlich kann der Bewegungsmechanismus des chirurgischen Fadenschneiders so gestaltet sein, daß sich Amboß und Klinge aufeinander zubewegen, damit der zu schneidende Faden nicht bewegt wird, was die Arbeit sehr erleichtert. Der beispielsweise mit LO bekannten scherenförmigen Griffen versehene Bewegungsmechanismus des Instruments ist dabei so gestaltet, daß mit einem der Arme Amboß und Klinge aufeinander zubewegt werden.In addition, the movement mechanism of the surgical thread cutter can be designed so that the anvil and blade move towards each other so that the thread to be cut is not moved, which makes the work much easier. The movement mechanism of the instrument, which is equipped with the scissor-shaped handles known from LO, is designed so that the anvil and blade are moved towards each other with one of the arms.

L5 Fig. 1 zeigt schematisch eine mögliche Ausführungsform der Erfindung. Dabei bezeichnet (1) den rohrförmigen Schaft des chirurgischen Fadenschneiders, (2) den im Schaft beweglichen, gekrümmten Amboß, (3) den Schlitz im Amboß (2), (4) die im Schaft bewegliche, auswechselbare Klinge, (5) den Betätigungsmechanismus mit den scherenförmigen Handgriffen (6), deren bewegliches Teil bei der Drehung um das Lager (7) über den Hebel (8) den Amboß und über den Hebel (9) die Klinge bewegt.L5 Fig. 1 shows a possible embodiment of the invention schematically. Here (1) designates the tubular shaft of the surgical thread cutter, (2) the curved anvil movable in the shaft, (3) the slot in the anvil (2), (4) the replaceable blade movable in the shaft, (5) the actuating mechanism with the scissor-shaped handles (6), the movable part of which, when rotating around the bearing (7), moves the anvil via the lever (8) and the blade via the lever (9).
