Description

Die Erfindung betrifft einen Operationstisch mit den Merkmalen des Oberbegriffes von Patentanspruch 1.The invention relates to an operating table having the features of the preamble of claim 1.

Mittels einer Patientenlagerungsplatte, die ein Lagerteil zur Lagerung eines Patienten und ein Verbindungsglied zum Verbinden der Patientenlagerungsplatte mit einer Operationstischsäule aufweist, kann ein Patient auf der von der Patientenlagerungsplatte ausgebildeten Lagerfläche zuverlässig gelagert werden für therapeutische Behandlungen und chirurgische Eingriffe und auch für diagnostische Verfahren. In vielen Fällen ist es wünschenswert, wenn der Patient während einer Operation eine geneigte oder gekippte Stellung einnimmt derart, dass die Patientenlagerungsplatte um eine quer zur Längsrichtung der Platte ausgerichtete Schwenkachse (sogenannte Trendelenburg-Stellung) oder um eine parallel zur Längsrichtung der Platte ausgerichtete Schwenkachse (sogenannte Kantung) geneigt ist. Hierzu sind Operationstischsäulen bekannt, deren Säulenkopf um mindestens eine horizontale Schwenkachse verschwenkt werden kann. Die Patientenlagerungsplatte kann auf den Säulenkopf aufgesetzt und mittels des Säulenkopfes in die gewünschte Trendelenburg-Stellung oder Kantung überführt werden. Der hierbei erzielbare Schwenkbereich ist allerdings beschränkt.By means of a patient support plate having a bearing member for supporting a patient and a connector for connecting the patient support plate to an operating table column, a patient can be reliably stored on the bearing surface formed by the patient support plate for therapeutic treatments and surgical procedures as well as for diagnostic procedures. In many cases, it is desirable for the patient to assume an inclined or tilted position during an operation such that the patient support plate is pivotable about a transverse axis to the longitudinal direction of the plate (so-called Trendelenburg position) or a pivot axis aligned parallel to the longitudinal direction of the plate (US Pat. so-called edging) is inclined. For this purpose, surgical table columns are known, the column head can be pivoted about at least one horizontal pivot axis. The patient support plate can be placed on the column head and transferred by means of the column head in the desired Trendelenburg position or edging. However, the achievable pivoting range is limited.

Aus der FR-A1-2 472 932 ist ein Operationstisch bekannt, bei dem die Patientenlagerungsplatte auf einem mehrteiligen Gestell gehalten ist, dessen Oberteil nach Art eines Säulenkopfes einer üblichen Operationstischsäule verschwenkt werden kann.From the FR-A1-2 472 932 An operating table is known in which the patient support plate is held on a multi-part frame, the upper part can be pivoted in the manner of a column head of a conventional operating table column.

Aus der EP 0 366 878 A1 ist ein Operationstisch bekannt, bei dem eine Patientenlagerungsplatte an einem schräg zur Horizontalen geneigten Achsbolzen eines Säulenkopfes verschwenkbar gelagert ist. Der Säulenkopf kann seinerseits um eine horizontal ausgerichtete Schwenkachse relativ zu einer Säulenbasis verschwenkt werden. Der Achsbolzen definiert eine Rollachse, die zur Längsachse der Patientenlagerungsplatte geneigt ist, und mittels des Säulenkopfes kann die gesamte Patientenlagerungsplatte um eine quer zu deren Längsachse geneigte Schwenkachse verschwenkt werden. Patientenlagerungsplatte und Operatlonstlschsäule sind unlösbar miteinander verbunden.From the EP 0 366 878 A1 an operating table is known in which a patient support plate is pivotally mounted on an inclined to the horizontal axis of a column head. The column head in turn can be pivoted about a horizontally oriented pivot axis relative to a column base. The axle pin defines a roll axis which is inclined to the longitudinal axis of the patient support plate, and by means of the column head, the entire patient support plate can be pivoted about a pivot axis inclined transversely to its longitudinal axis. Patient support plate and Operatlonstlschsäule are permanently connected.

Aufgabe der vorliegenden Erfindung ist es, einen Operationstisch der eingangs genannten Art derart weiterzubilden, dass er einen pattentenschonenderen Transport ermöglicht.Object of the present invention is to provide an operating table of the type mentioned in such a way that it allows a pattentenschonenderen transport.

Diese Aufgabe wird durch einen Operationstisch mit den Merkmalen von Patentanspruch 1 gelöst.This object is achieved by an operating table having the features of patent claim 1.

Der Operationstisch weist eine Patientenlagerungsplatte auf mit einem Schwenkmechanismus, mit dessen Hilfe die gesamte Patientenlagerungsplatte verschwenkt werden kann. Die Patientenlagerungsplatte kann somit unabhängig von der Operationstlschsäule um eine Quer- und/oder Längsachse verstellt werden zur Erzielung einer Trendelenburg-Stellung und/oder Kantung. Die Patientenlagerungsplatte kommt in Kombination mit einer Operationstischsäule mit verschwenkbarem Säulenkopf zum Einsatz. Durch den verschwenkbaren Säulenkopf ist ein erster Verschwenkberelch für die Patientenlagerungsplatte sichergestellt, und durch den Einsatz des Schwenkmechantsmusses wird der Patientenlagerungsplatte ein weiterer Schwenkbereich bereitgestellt, wobei sich die beiden Schwenkbereiche gegenseitig addieren. Dies hat zum einen den Vorteil, dass damit insgesamt größere Schwenkbereiche erzielt werden können, ohne dass der Schwenkbereich der Operationstischsäule vergrößert werden muss. Zum anderen kann mittels der Patientenlagerungsplatte in Kombination mit der einen verschwenkbaren Säulenkopf aufweisenden Operationstischsäule uneingeschränkt eine Trendelenburg-Stellung und gleichzeitig auch eine Kantung erzielt werden, indem beispielsweise mittels des Schwenkmechanismusses eine Trendelenburg-Stellung und mittels des verschwenkbaren Säulenkopfes die gewünschte Kantung herbeigeführt wird.The operating table has a patient support plate with a pivoting mechanism by means of which the entire patient support plate can be pivoted. The patient support plate can thus be adjusted independently of the surgical pillar column about a transverse and / or longitudinal axis to achieve a Trendelenburg position and / or edging. The patient support plate is used in combination with an operating table column with swiveling column head. By the pivotable column head a first pivoting elbow for the patient support plate is ensured, and by the use of Schwenkmechantsmusses the patient support plate another pivoting range is provided, wherein the two pivot areas add each other. This has the advantage that overall larger pivoting ranges can be achieved without the pivoting range of the operating table column being increased must become. On the other hand, by means of the patient support plate in combination with the pivotable column head having operating table column unrestricted Trendelenburg position and at the same time a Kantung be achieved, for example by means of the Schwenkmechanismusses Trendelenburg position and by means of the pivotable column head the desired edging is brought about.

Der erfindungsgemäße Operationstisch hat außerdem den Vorteil, dass die Patientenlagerungsplatte unabhängig von der Operationstischsäule eine Schwenkstellung, insbesondere eine Trendelenburg-Stellung, einnehmen kann. Diese Stellung kann während der Übergabe/Übernahme der Patientenlagerungsplatte auf bzw. von der Operationstischsäule beibehalten werden. Dies ermöglicht eine verbesserte Vorbereitung des Patienten für eine Operation. Die voreingestellte Schwenkstellung ermöglicht einen patientenschonenden Transport und verringert den Lagerungsaufwand.The operating table according to the invention also has the advantage that the patient support plate, independently of the operating table column, can assume a pivoting position, in particular a Trendelenburg position. This position can be maintained during transfer of the patient support plate to or from the operating table column. This allows for improved patient preparation for surgery. The preset swivel position allows for patient-friendly transport and reduces storage costs.

Da die Trendelenburgfunktion und die Kantungsfunktion räumlich voneinander getrennt werden können, sind die sonst üblichen gegenseitigen mechanischen Einschränkungen der Schwenkbereiche bei auf der Operationstischsäule aufsitzender Patientenlagerungsplatte nicht mehr gegeben.Since the Trendelenburg function and the Kantungsfunktion can be spatially separated from each other, the usual mutual mechanical limitations of the pivot areas are no longer given when seated on the operating table pedestal patient support plate.

Mittels des Schwenkmechanismus kann das Lagerteil der Patientenlagerungsplatte relativ zum Verbindungsglied verschwenkt werden, so dass das Verbindungsglied horizontal ausgerichtet auf den Säulenkopf der Operationstischsäule aufgesetzt werden kann, während das Lagerteil eine zur Horizontalen geneigte Stellung einnimmt.By means of the pivoting mechanism, the bearing part of the patient support plate can be pivoted relative to the connecting member, so that the connecting member can be placed horizontally aligned on the column head of the operating table column, while the bearing part assumes a position inclined to the horizontal.

Die Patientenlagerungsplatte kann nicht nur in Kombination mit einer Operationstischsäule zum Einsatz kommen, als Trägereinheit kann vielmehr auch ein Transportwagen vorgesehen sein, mit dem die Patientenlagerungsplatte lösbar verbindbar ist. Patientenlagerungsplatte, Operationstischsäule und Transportwagen können somit ein Patientenlagerungssystem ausbilden, wobei der Patient schonend transportiert und in für eine Operation optimaler Lage vom Transportwagen auf die Operationstischsäule übergeben werden kann.The patient support plate can be used not only in combination with an operating table column, but as a carrier unit can also be provided a dolly, with the patient support plate detachable is connectable. Patient support plate, operating table column and trolley can thus form a patient support system, the patient can be gently transported and transferred in an optimal position for the operation of the trolley on the operating table column.

Der Schwenkmechanismus ist zwischen dem Lagerteil und dem Verbindungsglied der Patientenlagerungsplatte angeordnet.The pivot mechanism is disposed between the bearing member and the connecting member of the patient support plate.

Günstig ist es, wenn der Schwenkmechanismus manuell betätigbar ist. So kann beispielsweise ein Schwenkhebel vorgesehen sein, mit dessen Hilfe die Patientenlagerungsplatte verschwenkt werden kann.It is advantageous if the pivoting mechanism is manually operable. For example, a pivot lever may be provided, with the aid of which the patient support plate can be pivoted.

Der Schwenkmechanismus kann ein Arretierungsglied aufweisen zum Arretieren der Patientenlagerungsplatte in einer gewünschten Schwenkstellung.The pivot mechanism may include a locking member for locking the patient support plate in a desired pivot position.

Alternativ oder ergänzend zu einer manuellen Betätigung kann vorgesehen sein, dass der Schwenkmechanismus motorisch betätigbar ist. Hierzu kann beispielsweise ein elektromotorischer oder hydraulischer Antrieb zum Einsatz kommen.Alternatively or in addition to a manual operation can be provided that the pivoting mechanism is actuated by a motor. For this purpose, for example, an electric motor or hydraulic drive can be used.

Bei einer besonders bevorzugten Ausführungsform weist die Patientenlagerungsplatte einen Antriebsmotor zum Verschwenken der Patientenlagerungsplatte auf. Als Antriebsmotor kommt vorzugsweise ein elektrischer Stellmotor zum Einsatz.In a particularly preferred embodiment, the patient support plate on a drive motor for pivoting the patient support plate. The drive motor is preferably an electric servomotor used.

Die Patientenlagerungsplatte kann zusätzlich zum Lagerteil weitere Plattenteile, beispielsweise eine Rückenplatte oder eine Beinplatte, aufweisen. Hierbei ist es von Vorteil, wenn am Lagerteil zumindest ein weiteres Plattenteil motorisch verstellbar gehalten ist. Bei einer derartigen Ausführungsform kann also nicht nur das Lagerteil relativ zum Verbindungsglied verschwenkt werden, sondern zusätzlich kann mindestens ein weiteres Plattenteil relativ zum Lagerteil verschwenkt werden. Dies gibt die Möglichkeit, einen Patienten beispielsweise für einen chirurgischen Eingriff in einer für den Eingriff möglichst schonenden Haltung zu lagern.The patient support plate may, in addition to the bearing part further plate parts, such as a back plate or a leg plate have. It is advantageous if the bearing part at least one further plate part is held by a motor adjustable. In such an embodiment, therefore, not only the bearing part can be pivoted relative to the connecting member, but in addition, at least one further plate part can be pivoted relative to the bearing part. This makes it possible to store a patient, for example for a surgical procedure, in a position that is as gentle as possible for the procedure.

Günstig ist es, wenn die Patientenlagerungsplatte einen Antriebsmotor zum Verstellen des mindestens einen weiteren Plattenteils aufweist. Konstruktiv aufwändige Getriebeelemente zwischen der Operationstischsäule und der Patientenlagerungsplatte zum Verstellen des weiteren Plattenteiles können dadurch entfallen. Als Antriebsmotor kommt bevorzugt ein elektrische Stellmotor zum Einsatz.It is advantageous if the patient support plate has a drive motor for adjusting the at least one further plate part. Constructively complex transmission elements between the operating table column and the patient support plate for adjusting the other plate part can be omitted. The drive motor is preferably an electric servomotor used.

Ein besonders großer Schwenkbereich wird bei einer vorteilhaften Ausführungsform der Erfindung dadurch erzielt, dass die Schwenkmechanik eine erste und eine zweite Schwenkachse definiert, die in Längs- oder Querrichtung der Patientenlagerungsplatte versetzt zueinander angeordnet sind und um die die Patientenlagerungsplatte teilweise verschwenkbar ist. Hierbei ist es von besonderem Vorteil, wenn zumindest eine der beiden Schwenkachsen bezogen auf die Längs- oder Querrichtung der Patientenlagerungsplatte in Höhe eines Endbereichs des Verbindungsgliedes angeordnet ist. Durch den Einsatz von zwei Schwenkachsen kann die Patientenlagerungsplatte um eine bezogen auf die Längs- oder Querachse der Patientenlagerungsplatte außermittig zum Lagerteil angeordnete Schwenkachse verschwenkt werden. Dies ermöglicht einen besonders großen Schwenkbereich, da die Patientenlagerungsplatte zum Absenken von einem ihrer Endbereiche um die in geringerem Abstand zu diesem Endbereich angeordnete Schwenkachse verschwenkt werden kann. Soll also die Patientenlagerungsplatte derart verschwenkt werden, dass deren Kopfteil eine besonders tiefe Stellung einnimmt, so kann sie um die in geringerem Abstand zu diesem Kopfteil angeordnete Schwenkachse verschwenkt werden, wohingegen bei einem Anheben des Kopfteiles eine Verschwenkbewegung um die in geringerem Abstand zu einer Beinplatte angeordnete Schwenkachse vorgenommen werden kann.A particularly large pivoting range is achieved in an advantageous embodiment of the invention in that the pivoting mechanism defines a first and a second pivot axis, which are offset in the longitudinal or transverse direction of the patient support plate to each other and around which the patient support plate is partially pivotable. In this case, it is of particular advantage if at least one of the two pivot axes is arranged at the level of an end region of the connecting element in relation to the longitudinal or transverse direction of the patient support plate. Due to the use of two pivot axes, the patient support plate can be eccentrically relative to the bearing part in relation to the longitudinal or transverse axis of the patient support plate arranged pivot axis are pivoted. This allows a particularly large pivoting range, since the patient support plate for lowering one of its end portions can be pivoted about the pivot axis arranged at a smaller distance from this end region. Thus, if the patient support plate to be pivoted so that the head part occupies a particularly low position, it can be pivoted about the arranged at a shorter distance to this head part pivot axis, whereas when lifting the head part pivoting about the arranged at a shorter distance to a leg plate Swivel axis can be made.

In den Figuren 1 bis 4 ist schematisch eine erste Ausführungsform eines erfindungsgemäßen Operationstisches dargestellt mit einer Patientenlagerungsplatte 10. Diese weist ein zentrales Lagerteil 12 auf, an dem einerseits eine Rückenplatte 13 und andererseits eine Beinplatte 14 angelenkt sind, die mittels in der Zeichnung nicht dargestellter, in die Patientenlagerungsplatte 10 integrierter Elektromotoren jeweils um eine quer zur Längsachse der Patientenlagerungsplatte 10 ausgerichtete Schwenkachse relativ zum Lagerteil 12 verschwenkbar sind. An der Rückenplatte 13 ist auf seiner dem Lagerteil 12 abgewandten Seite ein Kopfteil 15 verstellbar gehalten.In the FIGS. 1 to 4 schematically has a first embodiment of an operating table according to the invention shown with a patient support plate 10. This has a central bearing part 12, on the one hand a back plate 13 and on the other hand, a leg plate 14 are articulated by means not shown in the drawing, in the patient support plate 10 integrated electric motors each about a transverse to the longitudinal axis of the patient support plate 10 aligned pivot axis relative to the bearing part 12 are pivotable. On the back plate 13, a head part 15 is adjustably held on its side facing away from the bearing part 12 side.

Die Patientenlagerungsplatte 10 weist darüber hinaus ein Verbindungsglied 17 auf, mit dessen Hilfe sie mit dem Säulenkopf 19 einer Operationstischsäule 20 lösbar verbindbar ist. Der Säulenkopf 19 weist hierzu oberseitig eine ebene Stützfläche 22 auf, von der seitlich einander gegenüberliegend zwei Kopplungselemente in Form zweier Keilstücke nach oben abstehen, wobei in der Zeichnung nur ein Keilstück 23 dargestellt ist. Das Verbindungsglied 17 bildet unterseitg eine ebene Lagerfläche 25 aus, von der seitlich einander gegenüberliegend zwei nach unten gerichtete Stützwangen abstehen, wobei in der Zeichnung nur eine Stützwange 26 dargestellt ist. Die Stützwangen 26 weisen jeweils eine Aufnahme auf (nicht dargestellt), die beim Aufsetzen der Patientenlagerungsplatte 10 auf die Operationstischsäule 20 ein Keilstück 23 aufnehmen, wobei das Keilstück in der jeweiligen Aufnahme verriegelt werden kann.The patient support plate 10 also has a connecting member 17, by means of which it is detachably connectable to the column head 19 of an operating table column 20. The column head 19 has for this purpose on the top side a flat support surface 22, projecting from the side opposite each other two coupling elements in the form of two wedge pieces upwards, wherein only a wedge piece 23 is shown in the drawing. The connecting member 17 forms unterseitg from a flat bearing surface 25, from the side opposite each other projecting two downwardly directed support cheeks, wherein in the drawing, only one support cheek 26 is shown. The support cheeks 26 each have a receptacle (not shown), which receive a wedge piece 23 when placing the patient support plate 10 on the operating table column 20, wherein the wedge piece can be locked in the respective receptacle.

Die Patientenlagerungsplatte 10 weist außerdem einen Schwenkmechanismus 28 auf, der zwischen dem Lagerteil 12 und dem Verbindungsglied 17 angeordnet ist. Der Schwenkmechanismus 28 umfasst einen Lagerbock 29, der auf dem Verbindungsglied 17 aufsitzt und an dessen Oberseite das Lagerteil 12 angelenkt ist. Der Lagerbock 29 definiert eine quer zur Längsrichtung der Patientenlagerungsplatte 10 ausgerichtete Schwenkachse 30, um die das Lagerteil 12 zusammen mit der Rückenplatte 13, der Beinplatte 14 und dem Kopfteil 15 verschwenkt werden kann. Zum Verschwenken der Patientenlagerungsplatte 10 nimmt der Lagerbock 29 einen hydraulischen Antrieb in Form eines Kolben-Zylinderaggregates 32 auf, das einerseits am Lagerbock 29 und andererseits am Lagerteil 12 angelenkt ist.The patient support plate 10 also includes a pivot mechanism 28 disposed between the bearing member 12 and the link 17. The pivoting mechanism 28 includes a bearing block 29, which the connecting member 17 is seated and at the top of the bearing part 12 is articulated. The bearing block 29 defines a transverse to the longitudinal direction of the patient support plate 10 aligned pivot axis 30 about which the bearing member 12 can be pivoted together with the back plate 13, the leg plate 14 and the head part 15. For pivoting the patient support plate 10, the bearing block 29 receives a hydraulic drive in the form of a piston-cylinder unit 32, which is articulated on the one hand on the bearing block 29 and on the other hand on the bearing part 12.

Der Säulenkopf 19 der Operationstischsäule 20 ist in üblicher Weise um eine parallel zur Schwenkachse 30 ausgerichtete Schwenkachse 34 verschwenkbar. Hierzu ist der Säulenkopf 19 verstellbar an einer Säulenbasis 35 gehalten und kann mittels in der Zeichnung nicht dargestellter, an sich bekannter Antriebselemente, die in die Operationstischsäule 20 integriert sind, verschwenkt werden.The column head 19 of the operating table column 20 can be pivoted in the usual way about a pivot axis 34 aligned parallel to the pivot axis 30. For this purpose, the column head 19 is adjustably held on a pillar base 35 and can be pivoted by means not shown in the drawing, per se known drive elements, which are integrated into the operating table column 20.

Wie jedoch aus Figur 1 deutlich wird, kann die Patientenlagerungsplatte 10 unabhängig von einer Verschwenkbewegung des Säulenkopfes 19 um die Schwenkachse 30 verschwenkt werden zur Erzielung einer Trendelenburg-Stellung. Der mittels des Schwenkmechanismus 28 erzielbare Schwenkbereich der Patientenlagerungsplatte 10 kann um den mittels des Säulenkopfes 19 erzielbaren Schwenkbereich ergänzt werden. Dies wird aus Figur 3 deutlich, die die Patientenlagerungsplatte 10 in einer Stellung zeigt, in der sie zum einen um die Schwenkachse 30 und zum anderen auch um die Schwenkachse 34 verschwenkt ist, so dass die Beinplatte 14 eine stark angehobene Position und das Kopfteil 15 eine stark abgesenkte Position einnimmt.How, however, out FIG. 1 becomes clear, the patient support plate 10 can be pivoted independently of a pivoting movement of the column head 19 about the pivot axis 30 to achieve a Trendelenburg position. The achievable by means of the pivoting mechanism 28 pivoting range of the patient support plate 10 can be supplemented by the achievable by means of the column head 19 swivel range. This is going out FIG. 3 clearly showing the patient support plate 10 in a position in which it is pivoted on the one hand about the pivot axis 30 and on the other hand about the pivot axis 34, so that the leg plate 14 occupies a strongly raised position and the head part 15 a strongly lowered position.

Die Patientenlagerungsplatte 10 kann von der Operationstischsäule 20 abgenommen und auf einen in Figur 4 dargestellten Transportwagen 38 aufgesetzt werden. Bei der Übergabe kann die gesamte Patientenlagerungsplatte 10 eine geneigte Stellung einnehmen, da sie mittels des Schwenkmechanismus 28 relativ zur horizontal ausrichtbaren Lagerfläche 25 um die Schwenkachse 30 verschwenkt werden kann. Die Patientenlagerungsplatte 10 ermöglicht es somit insbesondere, eine Trendelenburg-Stellung, wie sie in Figur 4 dargestellt ist, einzustellen und einen auf der Patientenlagerungsplatte 10 ruhenden Patienten in dieser Stellung vom Transportwagen 38 an die Operationstischsäule 20 zu übergeben und in dieser Stellung von der Operationstischsäule 20 zu übernehmen. Dies stellt einen besonders schonenden Transport des Patienten und dessen verbesserte Vorbereitung für eine Operation sicher.The patient support plate 10 can be removed from the operating table column 20 and placed on a in FIG. 4 shown trolley 38 are placed. Upon transfer, the entire patient support plate 10 can assume an inclined position, since it can be pivoted by means of the pivot mechanism 28 relative to the horizontally alignable bearing surface 25 about the pivot axis 30. The patient support plate 10 thus makes it possible in particular, a Trendelenburg position, as in FIG. 4 is shown to adjust and transfer a resting on the patient support plate 10 patient in this position from the trolley 38 to the operating table column 20 and to take over in this position from the operating table column 20. This ensures a particularly gentle transport of the patient and its improved preparation for surgery.

In den Figuren 5, 6 und 7 ist eine zweite Ausführungsform eines Operationstisches dargestellt mit einer Patientenlagerungsplatte 40, die weitgehend identisch ausgestaltet ist wie die voranstehend erläuterte Patientenlagerungsplatte 10. Für identische Bauteile werden daher in den Figuren 5, 6 und 7 dieselben Bezugszeichen verwendet wie in den Figuren 1 bis 4. Bezüglich dieser Bauteile wird zur Vermeidung von Wiederholungen auf die voranstehenden Erläuterungen Bezug genommen.In the FIGS. 5, 6 and 7 is a second embodiment of an operating table shown with a patient support plate 40, which is designed substantially identical to the above-described patient support plate 10. For identical components are therefore in the FIGS. 5, 6 and 7 the same reference numerals as in the FIGS. 1 to 4 , With respect to these components, reference is made to the above explanations to avoid repetition.

Die Patientenlagerungsplatte 40 unterscheidet sich von der Patientenlagerungsplatte 10 durch den Einsatz eines Schwenkmechanismus 42, der zwei in Längsrichtung der Patientenlagerungsplatte 40 versetzt zueinander angeordnete Schwenkachsen 44 und 45 definiert. Die Patientenlagerungsplatte 40 kann mit Hilfe des Schwenkmechanismus 42 wahlweise um die erste Schwenkachse 44 oder um die zweite Schwenkachse 45 verschwenkt werden. Die beiden Schwenkachsen 44, 45 sind bezogen auf die Längsrichtung der Patientenlagerungsplatte 40 jeweils in Höhe eines Endbereiches des Verbindungsgliedes 17 angeordnet. In Figur 5 ist die Patientenlagerungsplatte 40 in einer um die erste Schwenkachse 44 verschwenkten Stellung dargestellt, wobei die Operationstischsäule 20 vertikal ausgerichtet ist. Figur 6 zeigt die Patientenlagerungsplatte 40, wobei sie einerseits um die erste Schwenkachse 44 und andererseits um die Schwenkachse 34 der Operationstischsäule 20 verschwenkt ist, um insgesamt das Kopfteil 15 sehr stark abzusenken.The patient support plate 40 differs from the patient support plate 10 by the use of a pivot mechanism 42 which defines two pivot axes 44 and 45 offset from one another in the longitudinal direction of the patient support plate 40. The patient support plate 40 can be selectively pivoted about the first pivot axis 44 or about the second pivot axis 45 by means of the pivot mechanism 42. The two Pivot axes 44, 45 are arranged relative to the longitudinal direction of the patient support plate 40 in each case at the level of an end region of the connecting member 17. In FIG. 5 the patient support plate 40 is shown in a pivoted about the first pivot axis 44 position, the operating table column 20 is vertically aligned. FIG. 6 shows the patient support plate 40, wherein it is pivoted on the one hand about the first pivot axis 44 and on the other hand about the pivot axis 34 of the operating table column 20 in order to lower the head part 15 very much.

Auch die Patientenlagerungsplatte 40 kann wahlweise mit der Operationstischsäule 20 oder mit dem Transportwagen 38 lösbar verbunden werden. In Figur 6 ist die Patientenlagerungsplatte 40 in einer um die zweite Schwenkachse 45 verschwenkten Stellung dargestellt, wobei sie auf dem Transportwagen 38 aufsitzt.Also, the patient support plate 40 can be selectively connected to the operating table column 20 or with the trolley 38 releasably. In FIG. 6 the patient support plate 40 is shown in a pivoted about the second pivot axis 45 position, wherein it is seated on the trolley 38.

Zum Verschwenken der Patientenlagerungsplatte 40 umfasst der Schwenkmechanismus 42 zumindest einen in der Zeichnung nicht dargestellten elektrischen Stellmotor. Alternativ kann ebenfalls ein hydraulischer Antrieb zum Einsatz kommen mit mindestens einem Kolben-Zylinderaggregat.For pivoting the patient support plate 40, the pivot mechanism 42 comprises at least one electric servomotor not shown in the drawing. Alternatively, a hydraulic drive can also be used with at least one piston-cylinder unit.
