Description

Die Erfindung betrifft einen Wundhaken für chirurgische Zwecke, der ein sterilisierbares Hakenblatt und einen sterilisierbaren Griff aufweist, wobei das Hakenblatt aus lichtleitendem Kunststoff besteh; und auf der dem Wundbereich zugekehrten Seite mit einer Lichtaustrittsfläche versehen ist, und der einen Faser- oder Flüssigkeitsleiter zur Zufuhr des Lichtes zum Hakenblatt besitzt.The invention relates to a retractor for surgical purposes, which has a sterilizable hook blade and has a sterilizable handle, the hook blade being made of light-conducting plastic; and on the the side facing the wound area is provided with a light exit surface, and the one fiber or Has liquid conductor for supplying the light to the hook blade.

Derartige Wundhaken sind aus der deutschen Offenlegungsschrifi 30 23 266 und aus dem deutschen Gebrauchsmuster 82 21 649 bekannt.Such retractors are from the German Offenlegungsschrift 30 23 266 and from the German utility model 82 21 649 known.

Der Erfindung liegt die Aufgabe zugrunde, gegenüber dem bekannten Wundhaken einen Wundhaken anzugeben, der preiswert und leicht herstellbar ist, eine rasche und sichere Betriebsbereitschaft ermöglicht und den sterilen Anforderungen im Operationsbereich genügt. The invention is based on the object of specifying a retractor compared to the known retractor, which is inexpensive and easy to manufacture, enables rapid and safe operational readiness and meets the sterile requirements in the operating area.

Gelöst wird die Aufgabe für einen Wundhaken der eingangs charakterisierten Art erfindungsgemäß dadurch, diiß das Hakenblatt aus Gamma-Strahlen-sterilisierbarem Kunststoff und der Handgriff aus dampfsteri-Iisierbarem Kunststoff besteht, daß das Hakenblatt als gesondertes Bauteil ausgebildet lösbar mit dem Handgriff verbunden ist und daß der Wundhaken im Handgriff mit dem Lichtleiter verbunden ist.The object is achieved according to the invention for a retractor of the type characterized at the outset by this is the hook sheet made of gamma-ray sterilizable Plastic and the handle made of Dampfsteri-Iisbaren plastic that the hook blade as a separate component is detachably connected to the handle and that the retractor is in the handle is connected to the light guide.

Der Wundhaken besteht aus mehreren Einzelteilen, die lösbar zu einer Einheit zusammengesetzt --ind. Der Wundhaken weist ein hakenförmig ausgebildetes, .ichtleitendes Hakenblatt auf. Von dem mehrteilig ausgebildeten Wundhaken ist das Hakenblatt abnehmbar ausgebildet und aus Gamma-Strahlen-sterilisierbarem Material und der Handgriff und die der übrigen Teile sind aus dampfsterilisierbarem Material. Zweckmäßigerweise weist das Hakenblatt und der Griff jeweils ein GewindeThe retractor consists of several individual parts that are detachably assembled into a unit. Of the Retractor has a non-conductive, hook-shaped design Hook blade on. The hook blade is designed to be removable from the multi-part retractor and made of gamma-ray sterilizable material and the handle and that of the remaining parts are made of steam sterilizable material. Appropriately, the hook blade and the handle each have a thread

!5 auf. Vorzugsweise ist das Hakenblatt mittels einer lösbaren Steckverbindung am Griff befestigbar, die entweder einrastbar mittels Rastverbinder oder einklerrmbar ausgebildet ist, wobei der Griff einen seitlichen Schlitz mit mindestens einem Führungs- und Halteteil aufweist.! 5 on. Preferably, the hook blade can be attached to the handle by means of a detachable plug connection, which either is designed to be latched by means of latching connectors or to be clipped in, the handle having a lateral slot having at least one guide and holding part.

Zweckmäßigenveise weist der Griff oder bevorzugt das Hakenblatt ein Anschlußteil für den Lichtleiter auf, das als Einlegeteil ausgebildet sein kann und gleichzeitig als Halteteil für das Hakenblatt dienen kann. Das Einlegeteil besteht vorteilhafterweise aus Edelstahl.Appropriately, the handle has or preferably that Hook sheet a connector for the light guide, which can be designed as an insert and at the same time as Holding part for the hook sheet can serve. The insert is advantageously made of stainless steel.

Die Vorteile des erfindungsgemäß ausgebildeten Wundhakens liegen darn, daß er teils als Einwegteil und teils als wiederverwendbares Teil ausgebildet ist. Weitere vorteilhafte Ausgestaltungen des Wundhakens sind den Unteransprüchen zu entnehmen.The advantages of the retractor designed according to the invention are that it is partly disposable and is partly designed as a reusable part. Further advantageous refinements of the retractor are to be found in the subclaims.

Gerade das als gesondertes Bauteil ausgebildete Hakenblatt, das unmittelbar mit dem Wundbereich in Berührung kommt, ist ein Einwegteil und aus Gamma-Strahlen-sterilisierbarem Kunststoff. Dieses Hakenblatt kann nach seiner Herstellung unter Reinraumbedingungen in eine abgeschlossene Hülle verpackt werden und ist dann noch im Bereich des Herstellers mittels Ga-nmastrahlen sterilisierbar. Im Gegensatz hierzu handelt es sich bei dem Handgriff um ein wiederverwendbares Teil, das aus dampfsterilisierbarem Kunststoff besteht.It is precisely the hook blade, which is designed as a separate component and which is in direct contact with the wound area is a disposable part and made of gamma-ray sterilizable plastic. This hook blade can be packed in a closed envelope after its production under clean room conditions and is then still in the range of the manufacturer using Ga-nma radiation sterilizable. In contrast, the handle is a reusable one Part made of steam-sterilizable plastic.

Dieser Handgriff, gegebenenfalls auch der Lichtleiter und das zur Verbindung vorgesehene Einlegeteil können unmittelbar vor der Operation zusammen mit dem üblichen Sterilisiergut in der ohnehin vorhandenen Dampfsterilisations-Anlage sterilisiert werden. Hierdurch wird im Gegensatz zu einem einstückig ausgebildeten Wundhaken eine erhebliche Kostenreduzierung erreicht. Kurz vor der Operation wird das Hakenblatt aus seiner sterilen Verpackung entnommen und im handgriff mit dem Lichtleiter verbunden. Auf dieseThis handle, possibly also the light guide and the insert provided for the connection can immediately before the operation together with the usual items to be sterilized in the already existing ones Steam sterilization system can be sterilized. This is in contrast to a one-piece Retractor achieved a significant cost reduction. Just before the operation, the hook blade is made removed from its sterile packaging and connected to the light guide in the handle. To this

so Weise ist der Wundhaken schnell betriebsbereit und sicher mit dem Lichtleiter verbunden. Außerdem kann, falls verschiedene Hakenblatt-Formate bereitgestellt werden, der Wundhaken der jeweiligen Operationswunde angepaßt werden.In this way, the retractor is quickly ready for use and securely connected to the light guide. In addition, if different hook blade formats are provided, the retractor of the respective surgical wound be adjusted.
