Description
BeschreibungDescription
Wundspreizer - Körper zur Aufnahme von verschiedenen Arbeitsenden (Valven).Retractor - body for accommodating different working ends (valves).
Wundspreizer weisen ein - je für sie übliches - Arbeitsende auf, das nicht einzeln austauschbar ist. Sie dienen zum Aufhalten des OP-Feldes. Da durch die Anatomie des Menschen bedingt nicht jeder menschliche Körper gleich gestaltet ist, müssen mehrere verschiedene Wundspreizer, mit verschiedenen Arbeitsenden, bereitgelegt werden. Dies bedeutet viel Platzverlust im OP und beim Sterilisieren.Retractors have a working end that is typical for them and cannot be individually replaced. They are used to hold the surgical field open. Since not every human body is the same due to human anatomy, several different retractors with different working ends must be prepared. This means a lot of space is lost in the operating room and during sterilization.
Problemproblem
Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, ein Instrument zu schaffen, das einfach und schnell in ein anderes umgestaltet werden kann, ohne daß die Stabilität zu sehr leidet bzw. Platz eingespart und Kosten reduziert werden können.The invention specified in claim 1 is based on the problem of creating an instrument that can be easily and quickly converted into another without the stability suffering too much and without space being saved and costs being reduced.
Erfindung
Dieses Problem wird mit der Maßnahme des Anspruchs 2 gelöst. invention
This problem is solved by the measure of claim 2.
Mit der Erfindung wird im angegebenen Fall erreicht, daß im zusammengesteckten Zustand die Stabilität und die Funktion des Instrumentes weitgehend nicht beeinträchtigt wird. Im zerlegten Zustand ist es platzsparend aufzubewahren und zu sterilisieren. Das Zerlegen und Zusammenbauen geht mühelos und schnell. Die Arbeitsenden, die von Fall zu Fall verschieden sein können, sind seperat herstellbar und können zur Ergänzung des Instrumentes in beliebigen Formen und Größen hergestellt werden .■The invention ensures that the stability and function of the instrument are largely unaffected when assembled. When disassembled, it can be stored and sterilized in a space-saving manner. Disassembly and assembly are quick and easy. The working ends, which can vary from case to case, can be manufactured separately and can be manufactured in any shape and size to complement the instrument.■
Vorteilhafte Ausgestaltung der Erfindung sind in den Ansprüchen 2: al, a2, a3, bl und b2 angegeben.Advantageous embodiments of the invention are specified in claims 2: al, a2, a3, bl and b2.
Die Weiterbildung nach Anspruch 2 ermöglicht eine flexiblere Anwendung und platzsparende Bereitstellung im OP.The further training according to claim 2 enables more flexible application and space-saving provision in the operating room.
Die Weiterbildung nach Anspruch al gewährleistet eine genaue Aufnahme der Arbeitsenden.Further training according to claim al ensures accurate recording of the employees.
Die Sicherung der eingestecken Arbeitsenden in Längsrichtung übernimmt die Ausgestaltung von Anspruch a2.The securing of the inserted working ends in the longitudinal direction is carried out by the design of claim a2.
Die Weiterbildung nach a3 gibt die Gewähr, daß die Arbeitsenden in ihrer Position fixiert werden.The further training according to a3 ensures that the workers are fixed in their position.
Die Ausarbeitung von Anspruch bl ermöglicht zusammen mit Anspruch a3 im zusammengesteckten Zustand das Verdrehen der Arbeitsenden.The elaboration of claim bl together with claim a3 enables the working ends to be twisted in the assembled state.
Die Längsfixierung der Arbeitsenden wird durch Anspruch b2 ermöglicht.The longitudinal fixation of the working ends is made possible by claim b2.
Ein Ausführungsbeispiel der Erfindung wird anhand der Figuren 1 bis 3 erläutert. An embodiment of the invention is explained using Figures 1 to 3.
Fig. 1 Die Arbeitsenden 2 sind eingerastet, somit ein komplettesFig. 1 The working ends 2 are locked in place, thus a complete
Instrument.Instrument.
Fig. 2 Der Schaft 9 der Arbeitsenden ist vergrößert dargestellt.Fig. 2 The shaft 9 of the working ends is shown enlarged.
Fig. 3 Ein Schnitt durch die Längsbohrung 3 im Griffteil (StangenFig. 3 A section through the longitudinal bore 3 in the handle part (rods
teil) .part) .
In den Figuren ist der Wundspreizer mit den Arbeitsenden 2, dem Griffteil 1, dem Stift 6, die Nute 5 und der Feder 4 mit dem Haken 8 dargestellt. Auch ist die Nute 7 im Schaft 9 und die Längsbohrung 3 gut sichtbar. Der Stift greift beim Einschieben der Arbeitsenden 2 in die Nute 5 ein uns sichert die Arbeitsenden auf Verdrehung. Gleichzeitig rastet die Feder 4 mit dem Hakenende 8 in die Nute 7 ein und hält das Arbeitsende im Griffteil 1 fest. Bei entfernten Arbeitsenden gemäß Fig. 2 und 3 wird der Schaft 9 am Arbeitsende mit der Nute 7 und dem Stift 6 gut sichtbar. Fig. 3 zeigt die Längsbohrung 3 die Nute 5 und die Feder 4 mit dem Hakenende 8.The figures show the retractor with the working ends 2, the handle part 1, the pin 6, the groove 5 and the spring 4 with the hook 8. The groove 7 in the shaft 9 and the longitudinal bore 3 are also clearly visible. The pin engages in the groove 5 when the working ends 2 are pushed in and secures the working ends against twisting. At the same time, the spring 4 with the hook end 8 engages in the groove 7 and holds the working end in the handle part 1. When the working ends are removed as shown in Fig. 2 and 3, the shaft 9 at the working end with the groove 7 and the pin 6 is clearly visible. Fig. 3 shows the longitudinal bore 3, the groove 5 and the spring 4 with the hook end 8.
