Zange zum Setzen von Tantal-ClipsPliers for setting tantalum clips

Die Erfindung bezieht sich auf eine Zange zum Setzen vonTantal-Clips zur Unterbindung der Eileiter von Frauen, bestehend aus einem Schaft mit proximaler Handhabe zum öffnenund Schließen einer distalen Clipzange unter Beobachtung mittels einer Optik.The invention relates to pliers for settingTantalum clips for ligating the fallopian tubes in women, consisting of a shaft with a proximal handle that can be openedand closing a distal clip forceps under observation by means of an optical system.

Zur Unterbindung der Eileiter von Frauen werden zwecks Schwangerschaftsverhütung sogenannte Clips aus Tantal mittelseiner Spezialzange unter optischer Sicht bei der sogenannten, gynäkologischen Laparoskopie angelegt. Dabei verwendete manzwei Zangeneinheiten, nämlich die eigentliche Zange zum Setzen der Clips und eine kleinere "Zange oder einen beweglichenHaken, um den Eileiter besser in den Bereich der eigentlichen Clipzange zu bringen und ihn bessererfassen zu können. Bei diesen bekannten Geräten sitzt die Optik in einem gesonderten Rohr neben der Clipzange, wasnachteilig ist, weil nicht unmittelbar in den Bereich des Operationsfeldes geblickt werden kann, obgleich die Optikdieses Feld mit einer Blickrichtung von 160° ansteuert und weil dadurch der Durchmesser des Gerätes vergrößert wird.To tie the fallopian tubes in women, so-called clips made of tantalum are used to prevent pregnancya special forceps under optical sight in the so-called, gynecological laparoscopy. One usedtwo pliers units, namely the actual pliers for setting the clips and a smaller "pliers" or a movable oneHooks to better bring the fallopian tube into the area of the actual clip forceps and bring it betterto be able to capture. In these known devices, the optics sit in a separate tube next to the clip pliers, whatis disadvantageous because it is not possible to look directly into the area of the operating field, although the opticscontrols this field with a viewing direction of 160 ° and because this increases the diameter of the device.

Die Aufgabe derErfindung besteht darin, einmal den Durchmesser der Zange mit Optik so gering wie möglich zu halten und zum anderendie Optik so anzuordnen, daß unmittelbar in das Zangenmaul bzw. in das Operationsfeld geblickt werden kann.The object of the invention is on the one hand to keep the diameter of the forceps with optics as small as possible and on the other handto arrange the optics so that one can look directly into the forceps jaws or into the operating field.

der
Diese Aufgabe wird nach/Erfindurgdadurch gelöst, daß bei der eingangs erwähnten Clipzange die Beobachtungsoptik mit Führungsrohrzentral durch einen zum öffnen und Schließen der Zangenbacken längsverschieblichen Schaft verläuft und Gisxal einenzwischen die Zangenbacken gerichteten Geradausblick aufweist. Dadurch v/ird gegenüber bekannten Clipzangen eine kleinereQuerschnittsfora erreicht, was für die Patientin wesentlich ist, und das Operationsfeld kann nunmehr direkt beobachtetwerden.
the
According to the invention, this object is achieved in that, in the above-mentioned clip pliers, the observation optics with guide tube runs centrally through a shaft which is longitudinally displaceable for opening and closing the pliers jaws and Gisxal has a straight outlook between the pliers jaws. As a result, compared to known clip forceps, a smaller cross-sectional shape is achieved, which is essential for the patient, and the operating field can now be observed directly.

Madenschrauben 11 und 12fixieren die Teile 2, 6, 8, 9 und 10 zu einer festen Einheit.an inner optics guide tube 6, which is firmly connected distally to a cylinder ring 7 by soldering or the like.A conical rotating part 8 with its annular collar 9 »and between the latter and the guide tube protrudes proximally into the flooding sleeve 26 supports a spacer bush 10. Grub screws 11 and 12fix parts 2, 6, 8, 9 and 10 to a fixed unit.

Der Zylinderring 7 ist distalwärts mit zwei längsgerichteten Ausnehmungen 13 versehen, in welchen die beiden Zangenbacken3 und 4 mit ihren Schenkeln 3a bzw. 4a lagern. In einer entsprechenden rechteckigen Ringnut im Zylinderring 7 und inbeiden Zangenschenkeln 3a, 4a ist ein Fixierring 14 satt eingelegt,der zwecks Einbringung in die Ringnut geschlitzt ist und der mit zv/ei kleinen Nieten 15 mit dem Zylinderring 7 zu einer festenEinheit verbunden ist.The cylinder ring 7 is provided distally with two longitudinal recesses 13 in which the two forceps jaws3 and 4 store with their legs 3a and 4a, respectively. In a corresponding rectangular ring groove in the cylinder ring 7 and ina fixing ring 14 is inserted snugly into both pliers legs 3a, 4a,which is slotted for the purpose of insertion into the annular groove and which is fixed with two small rivets 15 with the cylinder ring 7Unit is connected.

Die Zangenbacken 3, 4 mit ihren Schenkeln 3a, 4a sind nach außenfedernd ausgebildet entsprechend der dargestellten Form. Um eineAbdichtung im Instrument gegen austretendes Gas, z.B. CO2, ausder Eauchliöhle zu gewährleisten, sind distal und proximal inentsprechenden Ringnuten in den Teilen 7 und 10 Dichtungsringe 16, 17 eingelegt.The jaws 3, 4 with their legs 3a, 4a are designed to be resilient towards the outside in accordance with the shape shown. In order to ensure a seal in the instrument against escaping gas, eg CO2 , from the eau-de-sac, sealing rings 16, 17 are inserted distally and proximally in corresponding annular grooves in parts 7 and 10.

Auge 22 des Griffteiles 19 scharnierähnlich, also gelenkig,verbunden ist, hält die Zange stets in geöffneter Stellung. Das Zangengriffstück 18 ist fest durch Lötung mit der Überflutungshülse2 verbunden.Eye 22 of the handle part 19 hinge-like, that is, articulated,is connected, the pliers always hold in the open position. The pliers grip 18 is fixed by soldering to the flooding sleeve2 connected.

Griffteil 19 greift mit einer Vierkantausnehiaung am freien Ende(Fig.4) über den Ansatz 23a des U-förmig gestalteten Schlosses (Schiebers) 23 ein und ist mit diesem durch Lötung fest verbunden.Die innere Ausnehmung des Schlosses ist so gewählt, daß Platz für das Innenrohr 6 ist, dieses also umgriffen wird.Der Außenform des Schlosses angepaßt ist die Überflutungshüise 2, die auf einer dem Zangenhub entsprechenden Länge bei 24 ausgefrästist. Durch die Schloßgestaltung ist ein Verdrehen der axial beweglichen Einheit der Zange (Zangengriff 19 mit Schloß23 und Schaftrohr 1) unmöglich.Handle part 19 engages with a square recess at the free end(Fig. 4) over the extension 23a of the U-shaped lock (slide) 23 and is firmly connected to this by soldering.The inner recess of the lock is chosen so that there is space for the inner tube 6, so that it is encompassed.The outer shape of the lock is adapted to the flooding sleeve 2, which is milled out at 24 to a length corresponding to the stroke of the pliersis. The design of the lock means that the axially movable unit of the pliers (pliers handle 19 with lock23 and shaft tube 1) impossible.

Der Scherengriff 5 und das Zangenmaulteilpaar 3,4 brauchen abernicht in gleicher Ebene, wie gezeichnet, liegen. Es ist sogar vorteilhaft, den Griff etwa um 30 - 4-5° gegenüber dem Zangenmaulpaarversetzt anzuordnen, weil der Operateur beim Blick durch die Optik den Griff am Kopf hält und somit bei abgelenktemGriff besser hantieren kann.The scissors handle 5 and the pair of pliers jaws 3, 4, however, needdo not lie in the same plane as drawn. It is even advantageous to position the handle about 30 - 4-5 ° in relation to the pair of pliers jawsto be staggered because the surgeon holds the handle on the head when looking through the optics and thus when distractedHandle better.

Damit der Lichtanschlußstutzendie gewünschteI.zgebekommt, also das zum Lichtprojektor abgehendeLichtleitkabel den Arzt möglichst wenig behindert, ist die Verriegelung entsprechend gestaltet. Zur genauen Justierung hatdeshalb die Distansbuchse 10 eine spitzwinkelige Umlaufnut 30, in die die Fixierschraube 11 eingreift. Diese Justiermöglichkeitkann auch dazu verwendet werden, das zuvor geschilderte Zangenmaulpaar 3,4 in die entsprechende Lage zum Griff 5 zu bringen,and is firmly connected to the pliers by means of a union nut 28 and a screw 29.The lock is designed accordingly so that the light connection piece gets the desired pull, i.e. the fiber optic cable going to the light projector hinders the doctor as little as possible. For precise adjustment, the spacer sleeve 10 therefore has an acute-angled circumferential groove 30 in which the fixing screw 11 engages. This adjustment option can also be used to bring the pair of jaws 3, 4 described above into the appropriate position for the handle 5,

Die Optik hat eine Blickrichtung von 180°, um genau ins Operationsfeld,also zwischen die Zangenbacken 3,4 schauen zu können. Sie steht distal im Zylinderring 7 etwas zurück (Fig.2), umnicht beschädigt zu werden.The optics have a direction of view of 180 °, in order to be able toSo to be able to look between the jaws 3, 4.

Die Y/irkungsweise ist folgende: Zwischen die beiden geöffnetenZangenbacken 3,4 wird der Tantal-Clip 31 eingelegt. Hiernach wird die Zange mit Optik in die Bauchhöhle in bekannter Weise eingeführtund unter optischer Sicht der Eileiter umfaßt. Den erfaßten Griffteil 19 bewegt der Arzt gegen den Druck der Federin Richtung zum Zangengriffteil 18. Der Schaft 1 bewegt sich dabei gegenüber der Optik distalwärts, gleitet über die federndenZangenmaulteile 3,4 und schließt dabei das Zangenbackenpaar und damit auch den Clip 31. Der Eileiter ist abgeklemmt undder Durchgang im Eileiter gesperrt. Übt der Arzt jetzt keinen Druck mehr auf das Zangengriffteil 19 aus, dann drückt die Federden Griff in seine Ausgangslage, wobei gleichzeitig der SchaftThe way it works is as follows: Between the two open onesThe tantalum clip 31 is inserted into jaws 3, 4. The forceps with optics are then inserted into the abdominal cavity in a known mannerand includes the fallopian tubes from an optical point of view. The doctor moves the gripped part 19 against the pressure of the springin the direction of the forceps grip part 18. The shaft 1 moves distally with respect to the optics, slides over the resilient onesForceps jaw parts 3, 4 and thereby closes the pair of forceps jaws and thus also the clip 31. The fallopian tube is clamped andthe passage in the fallopian tube is blocked.
