Abstract
Description
Technisches GebietTechnical area
Die Erfindung betrifft einen Haltearm, insbesondere einen Haltearm für chirurgische Instrumente, umfassend miteinander kugelgelenkig verbundene Haltearmsegmente, die einseitig einen Gelenkkopf und anderseitig eine Gelenkpfanne aufweisen, wobei die Gelenkpfannen der Haltearmsegmente derart ausgebildet sind, dass sie den Gelenkkopf eines an ein Haltearmsegment angeordneten Haltearmsegments über dessen Äquator hinaus umgreifen. Der Haltearm weist darüber hinaus eine Spanneinrichtung zum Arretieren der Haltearmsegmente auf, die derart ausgeführt ist, dass der Haltearm in eine gelöste Stellung, eine vorgespannte Stellung zur Positionierung der Haltearmsegmente und in eine Arbeitsstellung, in welcher die Haltearmsegmente unbeweglich sind, gebracht werden kann.The invention relates to a support arm, in particular a support arm for surgical instruments, comprising each other with a ball joint connected Haltearmsegmente unilaterally have a condyle and on the other side a socket, wherein the joint sockets of the Haltearmsegmente are designed such that they the condyle of a arranged on a Haltearmsegment Haltearmsegments on the Embrace the equator. The support arm further comprises a tensioning device for locking the Haltearmsegmente, which is designed such that the support arm in a released position, a biased position for positioning the Haltearmsegmente and in a working position in which the Haltearmsegmente immovable, can be brought.
Stand der TechnikState of the art
Chirurgische Haltearme sind nach dem Stand der Technik bereits hinreichend bekannt. Diese Haltearme dienen vornehmlich der Fixierung von chirurgischen Instrumenten. Daneben finden Haltearme generell auch Verwendung im Alltagsgebrauch zum Halten verschiedenster Objekte wie Lampen, Kameras, Mikrofone, Spiegel, Schirme etc.Surgical holding arms are already well known in the art. These holding arms serve primarily for the fixation of surgical instruments. In addition, holding arms are generally also used in everyday use for holding various objects such as lamps, cameras, microphones, mirrors, umbrellas, etc.

Nachteilig bei den vorgenannten pneumatisch, hydraulisch oder elektrisch arretierbarer Haltearmsegmente ist, dass diese technisch aufwendig konstruiert sind und daher einen hohen Kostenaufwand erfordern. Darüber hinaus weisen pneumatische und hydraulische Systeme den Nachteil der schwierigen Abdichtung und besonders der schwierigen Reinigbarkeit auf, besonders durch die Sterilisation bei über 100°C.A disadvantage of the aforementioned pneumatically, hydraulically or electrically lockable Haltearmsegmente that they are technically complicated and therefore require a high cost. In addition, pneumatic and hydraulic systems have the disadvantage of difficult sealing and especially the difficult cleanability, especially by the sterilization at over 100 ° C.
Darstellung der ErfindungPresentation of the invention
Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, einen – insbesondere chirurgischen – Haltearm zu schaffen, der eine sichere Fixierung chirurgischer Instrumente, Werkzeuge und Geräte gewährleistet, dabei ohne zusätzliche Anschlüsse zur Kraftgewinnung mittels Pneumatik, Hydraulik oder Elektrik auskommt und die Erzeugung der Spannkraft konstruktiv einfach und auf Druck basierend erzeugt werden kann.The present invention is therefore based on the object to provide a - especially surgical - support arm, which ensures a secure fixation surgical instruments, tools and equipment, doing without additional connections for power by pneumatic, hydraulic or electrical and the generation of clamping force constructive can be generated easily and based on pressure.
Erfindungsgemäß wird die voranstehende Aufgabe mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Haltearms sind in Unteransprüchen angegeben.According to the invention the above object is achieved with the features of
Danach ist ein Haltearm der eingangs genannten Art dadurch gekennzeichnet, dass ein durch die Halterungssegmente geführtes Schubelement vorgesehen ist, wobei durch Verschiebung des Schubelements mittels der Spanneinrichtung gegen einen Anschlag in Schubrichtung die Gelenkköpfe der Halterarmsegmente durch Klemmung an dem über den jeweiligen Äquator der Gelenkköpfe hinaus umgreifenden Bereich der Gelenkpfannen in beliebiger Position verspannt werden.Thereafter, a holding arm of the type mentioned is characterized in that a guided by the support segments thrust element is provided, by displacement of the thrust element by means of the clamping device against a stop in the thrust direction of the rod ends of the Halterarmsegmente by clamping on the over the respective equator of the rod ends also embracing Area of the sockets in any position be braced.
In einer besonders vorteilhaften Ausführungsform der Erfindung besteht das Schubelement aus einer Vielzahl und jedenfalls in den Gelenkbereichen der Haltearmsegmente aneinander gelenkig angeordneter Glieder. Alternativ könnte das Schubelement auch aus einer (teil-)flexiblen Schubstange bestehen, welche vorzugsweise ausschließlich in den Gelenkbereichen der Halterungselemente flexibel ausgestaltet ist.In a particularly advantageous embodiment of the invention, the thrust element from a plurality and in any case in the joint regions of the Haltearmsegmente hingedly arranged members. Alternatively, the push element could also consist of a (partially) flexible push rod, which is preferably designed to be flexible only in the joint areas of the support elements.
Das Schubelement, welches vorzugsweise durch sämtliche Haltearmsegmente geführt ist, stößt endseitig gegen einen Anschlag. Mittels der Spanneinrichtung, welche bevorzugt aus einem Spannhebel besteht, wird das Schubelement endseitig gegen den Anschlag gedrückt und erzeugt somit in den Kugelgelenken der einzelnen Segmente eine Spannung, die bewirkt, dass die Gelenkköpfe der Halterarmsegmente durch Klemmung an dem über den jeweiligen Äquator der Halterungselemente hinaus umgreifenden Bereich der Gelenkpfannen arretiert werden.The thrust element, which is preferably guided by all Haltearmsegmente, abuts the end against a stop. By means of the clamping device, which preferably consists of a clamping lever, the thrust element is pressed end against the stop and thus generates in the ball joints of the individual segments a tension which causes the rod ends of the Halterarmsegmente by clamping on the above the respective equator of the support elements addition encompassing area of the joint sockets are locked.
