Abstract
Chirurgisches endoskopisches Zangen- oder Schereninstrument mit zwei am distalen Ende eines Schaftrohres (1) gelagerten Branchen (3, 4) und einer im Rohr (1) angeordneten, von dessen proximalen Ende her angetriebenen Stange (6), die über eine Getriebeverbindung (7, 8) die Branchen (3, 4) zu ihrer gegenläufigen Verschwenkung antreibt, wobei die Getriebeverbindung als Zahnradgetriebe (7, 8) ausgebildet ist, das wenigstens auf einem Umfangsteil mit Zahnung versehene Zahnräder (7) an jeder Branche (3, 4) und ein gezahntes Triebelement (8) am distalen Ende der Stange (6) aufweist, dadurch gekennzeichnet, dass die Branchen (3, 4) auf einer gemeinsamen, quer zum Schaftrohr (1) angeordneten Achse (2) in axialem Abstand gelagert sind und auf ihrer einander zugewandten Seite koaxial zur Achse angeordnete Zahnräder tragen, die als Kegelräder (7) ausgebildet sind und beide mit dem als Kegelstirnrad (8) ausgebildeten Triebelement an der drehangetriebenen Stange (6) kämmen.surgical Endoscopic forceps or scissors instrument with two at the distal end End of a shaft tube (1) mounted branches (3, 4) and one in the Tube (1) arranged, driven from the proximal end thereof Rod (6), over a gear connection (7, 8) the branches (3, 4) for their opposite pivoting drives, wherein the transmission connection as a gear transmission (7, 8) is formed, at least on a peripheral part with teeth provided gears (7) on each branch (3, 4) and a toothed drive element (8) on distal end of the rod (6), characterized in that the branches (3, 4) on a common, transverse to the shaft tube (1) arranged axis (2) are mounted at an axial distance and on wear their gears facing each other coaxially with the axis, as bevel gears (7) are formed and both with the trained as bevel gear (8) Comb the drive element on the rotary driven rod (6).
Description
Die Erfindung betrifft ein Zangen- oder Schereninstrument der im Oberbegriff des Anspruches genannten Art.The The invention relates to a forceps or scissors instrument in the preamble of the claim mentioned type.
Solche endoskopischen Instrumente weisen Branchen auf, die als Zangen oder Scherenbranchen ausgebildet sein können und in beiden Ausführungen in derselben Kinematik gegenseitig zur Öffnungs- oder Schließbewegung bewegt werden. Die Branchen sind dabei am distalen Ende eines Schaftrohres gelagert, in welchem eine Stange zum Antrieb der Branchen angeordnet ist. Die Stange wird ihrerseits vom proximalen Ende des Schaftrohres her angetrieben.Such Endoscopic instruments have branches that act as pliers or Scherenbranchen can be trained and in both versions in the same kinematics mutually to the opening or closing movement to be moved. The sectors are mounted at the distal end of a shaft tube, in which a rod for driving the branches is arranged. The rod in turn is from the proximal end of the shaft tube driven.
Bekannte gattungsgemäße Instrumente weisen unterschiedliche Arten der Getriebeverbindung auf, die beispielsweise aus mehrgelenkig verbundenen Hebeln, Führungskurven und Nocken oder dergleichen besteht. Die bekannten Getriebeverbindungen weisen alle konstruktive Begrenzungen auf, die sich vor allem aus dem erforderlichen geringen Außendurchmesser der Instrumente ergeben.Known generic instruments have different types of transmission connection, for example from multi-jointed levers, guide cams and cams or the like exists. The known transmission connections have all constructive limitations, which are mainly due to the required small outer diameter of instruments.
Es sind auch Zangen mit Zahnradgetrieben bekannt. So zeigt das JP-Abstract 7009353 eine Werkzeugzange hier nicht verwendbarer Bauart, bei der die Branchen über ein Zahnradgetriebe angetrieben sind.It also pliers with gear drives are known. This is how the JP abstract shows 7009353 a tool tongs here not usable type, in which the industries over a gear transmission are driven.
Das
Die
Die Aufgabe der vorliegenden Erfindung besteht darin, bei einem gattungsgemäßen Instrument eine neuartige Getriebeverbindung mit anderen konstruktiven Möglichkeiten vorzusehen.The Object of the present invention is in a generic instrument a novel transmission connection with other design options provided.
Diese Aufgabe wird mit den Merkmalen des Anspruches gelöst.These Task is solved with the features of the claim.
Erfindungsgemäß ist bei einem gattungsgemäßen Instrument die Getriebeverbindung als Zahnradgetriebe mit Kegelrädern ausgebildet und wird von einer dreh angetriebenen Stange angetrieben. Dadurch ergeben sich gegenüber Instrumenten mit bekannten Getriebeverbindungen völlig neue konstruktive Möglichkeiten.According to the invention is at a generic instrument the transmission connection designed as a gear transmission with bevel gears and is driven by a rotatably driven rod. Thereby arise opposite Instruments with known transmission connections completely new constructive possibilities.
In den Zeichnungen ist die Erfindung beispielsweise und schematisch dargestellt.In In the drawings, the invention is for example and schematically shown.
Es zeigen:It demonstrate:
In den Zeichnungen sind Zangen dargestellt, bei denen die beweglichen Branchen als Zangenbranchen ausgebildet sind.In The drawings show pliers in which the movable Branches are trained as tongs industries.
Ersichtlich können die Zangen durch andere Ausbildung der distalen Endbereiche der Branchen auch als Scheren ausgebildet sein.apparent can the pliers by other training of the distal end of the Branches should also be designed as scissors.
