Description
Griffteil zur Aufnahme von chirurgischen Instrumenten.Handle for holding surgical instruments.
Normalerweise werden Griffteile im Zwei-Finger-System verwendet, da dies die gewohnte Operationsmethode ist. Griffteile üblicher Bauart verfügen über ein fest vernietetes Führungsteil, indem je nach Operationsart unterschiedliche Instrumentenformen verwendet werden . Bei diesen Griffteilen muß der Operateur durch Manipulieren des Instrumentes oder drehen seiner Hand die Operation fortsetzen, was negative Auswirkungen auf das Operationsergebnis haben kann. Deshalb vertreibt eine schweizer Fa. ein drehbares Instrument, welches allerdings einen aufwendigen und anfälligen Mechanismus besitzt. Außerdem wird dieses Instrument im Ein-Finger-Systern betätigt.Normally, handles are used in the two-finger system, as this is the usual method of operation. Handles of the usual design have a firmly riveted guide part, in which different instrument shapes are used depending on the type of operation. With these handles, the surgeon has to continue the operation by manipulating the instrument or turning his hand, which can have a negative impact on the result of the operation. For this reason, a Swiss company sells a rotating instrument, which, however, has a complex and vulnerable mechanism. In addition, this instrument is operated in the one-finger system.
Problemproblem
Der angegebenen Erfindung im Anspruch 1 liegt das Problem zugrunde, ein drehbares Führungsteil einzubauen, ohne das gewohnte Griffteil maßgebend zu verändern.The invention specified in claim 1 is based on the problem of installing a rotatable guide part without significantly changing the usual handle part.
Erfindunginvention
Dieses Problem wird mit den Maßnahmen des Anspruches 1 gelöst.This problem is solved by the measures of claim 1.
Mit der Erfindung ist es möglich vor oder während der Operation das Führungsteil zu drehen, um die beste Operationshaltung zu erreichen. So kann auch während dem Operationsvorgang das Führungsteil gedreht werden, um etwa Fremdkörper drehend aus dem Operationsfeld zu entfernen. Mit dieser baulichen Anordnung ist nicht nur das Einsetzen von Pinzetten, sondern auch das Einsetzen von Scheren (Längs- und Querschneidend) in das Führungsteil möglich.The invention makes it possible to rotate the guide part before or during the operation in order to achieve the best operating position. The guide part can also be rotated during the operation in order to remove foreign bodies from the operating field by rotating it. This structural arrangement not only makes it possible to insert tweezers, but also scissors (lengthwise and crosswise cutting) into the guide part.
Das Ausführungsbeispiel der Erfindung wird anhand, der Figuren 1
bis 3 dargestellt. Es zeigen:
Fig. 1 das Griffteil, geometrischThe embodiment of the invention is illustrated in Figures 1 to 3. They show:
Fig. 1 the handle part, geometric
Fig. 2 das Führungsrohr mit öem vorderen Mbs-chnitt des Griffteils im HalbschnittFig. 2 the guide tube with the front Mbs section of the handle part in half section
Fig. 3 eine Auswahl von Operationsinstrumenten, darunter mit und 3.2 zwei Scheren und mit 3.3 und 3.4 zwei Pinzetten.Fig. 3 a selection of surgical instruments, including two scissors (3.2) and two forceps (3.3) and 3.4.
In den Figuren ist das Griffteil im entspannten Zustand dargestellt, mit den Federdruckteilen 1, Führungsteil 2, Drehrad 3, Führungsrohr 4, Schieber 5, Mittelteil 6, Befestigungsbolzen 7, Feder 8, Halteteil 9, Aufnahmemutter 10, Kontermuttern 11, Schenkel 12.In the figures, the handle part is shown in the relaxed state, with the spring pressure parts 1, guide part 2, rotary wheel 3, guide tube 4, slide 5, middle part 6, fastening bolt 7, spring 8, holding part 9, receiving nut 10, lock nuts 11, leg 12.
Im entspannten Zustand sind die Operationsinstrumente wie in Fig. 3 dargestellt. Sobald der Operateur die Federdruckteile 1 zusammendrückt, wird das Führungsrohr 4 oder bei Fig 3.1 ein Scherenblatt nach vorne gedrückt, um die vorgesehene Operation durchzuführen. Dabei wird ein Scherenblatt im Befestigungsbolzen 7 mit Hilfe einer Kontermutter 11 befestigt, während das Führungsrohr 4 im Führungsteil 2 befestigt ist. Bei den Fig. 3.2 bis 3.4 wird das Führungsrohr 4 im Befestigungsbolzen befestigt, während die Operationsinstrumente mit der Kontermutter 11 im Führungsteil 2 befestigt werden. Bei diesen Vorgängen wird durch das Zusammendrücken der Federdruckteile 1 der Schieber 5 nach vorne gedrückt, da beide Teile beweglich über die Schenkel 12 verbunden sind. Gleichzeitig wird der Befestigungsbolzen 7 nach vorne gedrückt, der wiederum, wie schon erwähnt, ein Scherenblatt oder das Führungsrohr 4 in Bewegung setzt. Als Anschlag dient das Aufsetzen der Federdruckteile 1 auf das Mittelteil 6. Läßt der Operateur durch Wegnahme des Druckes auf die Federdruckteile 1 diese wieder in ihre Ruhestellung zurückfedern, drückt gleichzeitig die Feder 8 den Befestigungsbolzen 7 zurück in dessen Endlage. Während oder vor dem Gebrauch des Griffteils ist durch Drehen mit dem Drehrad 3 die optimale Stellung der Operationsinstrumente erreichbar, da das Drehrad 3 um 360 Grad drehbar ist. Beim Drehen durch das Drehrad 3 bewegt sich das Führungsteil 2, Halteteil 9, Feder 8, Befestigungsbolzen 7 und Führungsrohr 4 mit. Die Aufnahmemutter 10 dient zum Befestigen auf dem Mittelteil 6, sowie zum Aufnehmen und Führen des Drehmechanismus.In the relaxed state, the surgical instruments are as shown in Fig. 3. As soon as the surgeon presses the spring pressure parts 1 together, the guide tube 4 or, in Fig. 3.1, a scissor blade is pushed forwards in order to carry out the intended operation. In this process, a scissor blade is fastened in the fastening bolt 7 using a lock nut 11, while the guide tube 4 is fastened in the guide part 2. In Figs. 3.2 to 3.4, the guide tube 4 is fastened in the fastening bolt, while the surgical instruments are fastened in the guide part 2 using the lock nut 11. During these processes, the slider 5 is pushed forwards by pressing the spring pressure parts 1 together, since both parts are movably connected via the legs 12. At the same time, the fastening bolt 7 is pushed forwards, which in turn, as already mentioned, sets a scissor blade or the guide tube 4 in motion. The stop is the placement of the spring pressure parts 1 on the middle part 6. If the surgeon allows the spring pressure parts 1 to spring back into their rest position by removing the pressure, the spring 8 simultaneously presses the fastening bolt 7 back into its end position. During or before use of the handle part, the optimal position of the surgical instruments can be achieved by turning the rotary wheel 3, as the rotary wheel 3 can be rotated 360 degrees. When the rotary wheel 3 is turned, the guide part 2, holding part 9, spring 8, fastening bolt 7 and guide tube 4 move with it. The retaining nut 10 is used to fasten it to the middle part 6 and to hold and guide the rotating mechanism.
