Description

Die vorliegende Erfindung betrifft einen Operationstisch mit einer Säule, auf der eine Patientenauflage so gelagert ist, dass sie um eine sich quer zur Patientenauflage erstreckende Achse und um eine sich längs zur Patientenauflage erstreckende Achse verschwenkbar ist. Bei derartigen Operationstischen, die aus dem Stand der Technik bekannt sind, kann die Liegefläche standardmäßig um ±30° in der Querachse (auch genannt Trend oder Neigung) und um ±20° in der Längsachse (auch genannt Tilt oder Kantung) verstellt werden. Aufgrund konstruktiver Einschränkungen ist eine vollumfängliche Kombination beider Bewegungen nicht immer gegeben.The present invention relates to an operating table with a column on which a patient support is mounted so that it can be pivoted about an axis extending transversely to the patient support and about an axis extending longitudinally of the patient support. In such operating tables, which are known from the prior art, the lying surface by default by ± 30 ° in the transverse axis (also called trend or inclination) and by ± 20 ° in the longitudinal axis (also called tilt or edging) can be adjusted. Due to constructive limitations, a full combination of both movements is not always given.

Bei den aus dem Stand der Technik bekannten Operationstischen ist es bekannt, eine kardanische Lagerung der Patientenauflage vorzusehen, bei der mit Hilfe von zwei Hubzylindern die Liegefläche um zwei zueinander senkrechte Drehachsen verschwenkt wird. Da die beiden Drehachsen zumindest annähernd zentrisch zur Säule angeordnet sind, kann die Patientenauflage nicht in einem gewünschten Ausmaß, d.h. mit den gewünschten großen Tiltwinkeln und Trendwinkeln verschwenkt werden.In the operating tables known from the prior art, it is known to provide a gimbal bearing of the patient support, in which by means of two lifting cylinders, the lying surface is pivoted about two mutually perpendicular axes of rotation. Since the two axes of rotation are at least approximately centric to the column, the patient support can not to a desired extent, i. to be swiveled with the desired large tilt angles and trend angles.

Es ist die Aufgabe der vorliegenden Erfindung, einen Operationstisch der eingangs genannten Art derart weiterzubilden, dass mit konstruktiv einfachen und kostengünstigen Mitteln große Trend- und Tiltwinkel erzielbar sind.It is the object of the present invention to develop an operating table of the type mentioned in such a way that with structurally simple and inexpensive means large trend and tilt angle can be achieved.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1 und insbesondere dadurch, dass die Patientenauflage mit der Säule über ein zwei Gelenkteile umfassendes Gelenk verbunden ist, wobei das Gelenk um eine vertikale Drehachse drehbar ist. Durch die Möglichkeit, das Gelenk um eine vertikale Drehachse zu verdrehen, kann dieses so gedreht werden, dass eine Schwenkachse des Gelenks entweder an der einen oder der anderen Seite der Patientenauflage oder in Richtung des Kopfendes oder des Fußendes der Patientenauflage positioniert ist. Auf diese Weise lassen sich sehr große Trend- und Tiltwinkel erreichen, da die Patientenauflage nicht mehr um eine Schwenkachse verschwenkt wird, die im Wesentlichen zentrisch angeordnet ist. Vielmehr kann die Schwenkachse um die vertikale Drehachse so verdreht werden, dass die Schwenkachse auf derjenigen Seite der Patientenauflage angeordnet ist, in deren Richtung verschwenkt werden soll. Mit anderen Worten kann die Schwenkachse des Gelenks an diejenige Stelle gebracht werden, an der die Neigung oder Kantung gewünscht ist.The solution of this object is achieved by the features of claim 1 and in particular by the fact that the patient support is connected to the column via a joint comprising two joint parts, wherein the joint is rotatable about a vertical axis of rotation. The ability to rotate the hinge about a vertical axis of rotation allows it to be rotated so that a pivot axis of the hinge is positioned either on one or the other side of the patient support or toward the head end or foot end of the patient support. In this way, very large trend and tilt angle can be achieved because the patient support is no longer pivoted about a pivot axis, which is arranged substantially centrally. Rather, the pivot axis about the vertical axis of rotation can be rotated so that the pivot axis is arranged on that side of the patient support, to be pivoted in the direction. In other words, the pivot axis of the joint can be brought to the point where the inclination or edging is desired.

Mit der erfindungsgemäßen Lösung sind außerordentlich große Schwenkwinkel von bis zu 90° möglich. Gleichzeitig ist es möglich, die Patientenauflage relativ zur Säule zu verschwenken, falls dies gewünscht ist.With the solution according to the invention exceptionally large pivoting angle of up to 90 ° are possible. At the same time it is possible to pivot the patient support relative to the column, if desired.

Vorteilhafte Ausführungsformen der Erfindung sind in der Beschreibung, der Zeichnung und in den Unteransprüchen beschrieben.Advantageous embodiments of the invention are described in the description, the drawings and the subclaims.

In einer ersten vorteilhaften Ausführungsform kann das Gelenk selbst genau eine Schwenkachse aufweisen, die insbesondere horizontal orientiert sein kann. Auf diese Weise lässt sich ohne Verwendung eines Kardangelenks die Patientenauflage in jede gewünschte Richtung verkippen, wobei durch Verschwenken um die vertikale Drehachse die Schwenkachse des Gelenks an die gewünschte Stelle gebracht werden kann, an der die maximale Neigung oder Kantung gewünscht ist.In a first advantageous embodiment, the joint itself can have exactly one pivot axis, which in particular can be oriented horizontally. In this way, without the use of a universal joint, the patient support can be tilted in any desired direction, the pivot axis being pivoted about the vertical axis of rotation of the joint can be brought to the desired location where the maximum inclination or edging is desired.

Nach einer weiteren vorteilhaften Ausführungsform kann die Patientenauflage mit der Säule über ein einziges Gelenk verbunden sein, wobei die Relativposition zwischen der Patientenauflage und dem Gelenk und/oder die Relativposition zwischen der Säule und dem Gelenk veränderbar ist. Auf diese Weise kann beispielsweise das Gelenk zwischen Patientenauflage und Säule hindurchgedreht werden, ohne dass sich die Position der Patientenauflage relativ zur Säule verändert.According to a further advantageous embodiment, the patient support can be connected to the column via a single joint, wherein the relative position between the patient support and the joint and / or the relative position between the column and the joint is variable. In this way, for example, the joint between the patient support and the pillar can be rotated without the position of the patient support being changed relative to the pillar.

Nach einer weiteren vorteilhaften Ausführungsform kann die Schwenkachse des Gelenks exzentrisch zur Mittelachse der Säule und/oder exzentrisch zur Mitte der Patientenauflage angeordnet sein. Auf diese Weise sind außerordentlich große Trend- und Tiltwinkel möglich, da die Schwenkachse des Gelenks an die Stelle verdreht werden kann, an der die Neigung oder Verkantung gewünscht ist.According to a further advantageous embodiment, the pivot axis of the joint may be arranged eccentrically to the center axis of the column and / or eccentrically to the center of the patient support. In this way, extremely large trend and tilt angle are possible because the pivot axis of the joint can be rotated to the point where the inclination or tilting is desired.

Nach einer weiteren vorteilhaften Ausführungsform ist lediglich ein einziger Hubzylinder vorgesehen, um die Neigung der Patientenauflage zu verändern. Hierdurch lässt sich mit nur einem einzigen translatorisch wirkenden Antriebselement eine beliebige Neigung der Patientenauflage erzielen. Weiterhin kann zur Neigungsverstellung der Patientenauflage ein Hubzylinder vorgesehen sein, der über ein Kugelgelenk mit dieser verbunden ist. Dies stellt eine konstruktiv einfache und damit kostengünstige Realisierung dar.According to a further advantageous embodiment, only a single lifting cylinder is provided to change the inclination of the patient support. As a result, any inclination of the patient support can be achieved with only a single translationally acting drive element. Furthermore, for tilt adjustment of the patient support a lifting cylinder may be provided which is connected via a ball joint with this. This represents a structurally simple and therefore cost-effective implementation.

Weiterhin kann es vorteilhaft sein, wenn für ein Verschwenken der Patientenauflage zwei und insbesondere genau zwei Antriebe vorgesehen sind, die vorzugsweise durch eine Steuerung synchronisiert antreibbar sind. Auf diese Weise lassen sich die beiden Antriebe so betreiben bzw. antreiben, dass die Patientenauflage in beliebige Richtungen verkippt bzw. verschwenkt werden kann, ohne dass diese selbst ungewünschte Bewegungen durchführt.Furthermore, it may be advantageous if two and in particular exactly two drives are provided for pivoting the patient support, which are preferably drivable synchronized by a controller. In this way, the two drives can be operated or drive so that the patient support can be tilted or pivoted in any direction, without this even performs unwanted movements.

Eine konstruktiv einfache und kostengünstige Variante ergibt sich, wenn als Antrieb zum Verschwenken der Patientenauflage insgesamt nur genau ein Hubzylinder und zwei Drehantriebe vorgesehen sind.A structurally simple and cost-effective variant results when only exactly one lifting cylinder and two rotary drives are provided as a drive for pivoting the patient support.

Nach einer vorteilhaften Ausführungsform ist das Gelenk als Drehschemel ausgebildet, dessen beide Gelenkteile um eine horizontale Achse gegeneinander verschwenkbar sind. Ein solcher Drehschemel bietet eine gute Stabilität und kann so ausgebildet werden, dass beide Gelenkteile jeweils eine Öffnung aufweisen, wobei ein Hubzylinder durch die Öffnungen der beiden Gelenkteile hindurchgeführt ist. Hierdurch kann bei kompakter Bauweise die gewünschte variable Verschwenkbarkeit realisiert werden. Zur Erhöhung der Stabilität kann es vorteilhaft sein, wenn die beiden Gelenkteile als Ring ausgebildet sind.According to an advantageous embodiment, the joint is designed as a turntable, the two hinge parts are pivotable about a horizontal axis against each other. Such a turntable provides good stability and can be formed so that both hinge parts each have an opening, wherein a lifting cylinder is passed through the openings of the two hinge parts. In this way, the desired variable pivotability can be realized in a compact design. To increase the stability, it may be advantageous if the two joint parts are formed as a ring.

Schließlich kann es vorteilhaft sein, wenn das Gelenk um die vertikale Drehachse um 360° drehbar ist, da in diesem Fall eine maximale Flexibilität gegeben ist.Finally, it may be advantageous if the joint is rotatable about the vertical axis of rotation by 360 °, since in this case maximum flexibility is given.

Nachfolgend wird die vorliegende Erfindung rein beispielhaft anhand einer vorteilhaften Ausführungsform und unter Bezugnahme auf die beigefügten Zeichnungen beschrieben. Es zeigen:

Fig. 1 zeigt in zwei perspektivischen Ansichten einen Operationstisch mit einer Säule 12, auf der eine Patientenauflage 10 gelagert ist. Von der Patientenauflage 10 sind zur besseren Darstellung lediglich eine Grundplatte 11 und eine Seitenwange 13 dargestellt. Es versteht sich jedoch, dass die Patientenauflage 10 noch weitere Bauelemente wie Auflagen, Polsterelemente und dergleichen umfasst. Zudem ist bei der Darstellung der Fig. 1 nur eine Seitenwange 13 dargestellt, obwohl, wie auch die Fig. 2 und Fig. 5 zeigen, zwei parallele Seitenwangen 13 und 13' vorgesehen sind. Fig. 1 shows in two perspective views of an operating table with a column 12, on which a patient support 10 is mounted. Of the patient support 10, only a base plate 11 and a side wall 13 are shown for clarity. It is understood, however, that the patient support 10 also includes other components such as supports, upholstery elements and the like. In addition, in the presentation of the Fig. 1 only one side cheek 13 shown, though, as well as the Fig. 2 and Fig. 5 show two parallel side walls 13 and 13 'are provided.

Die Patientenauflage 10 ist auf der Säule 12 so gelagert, dass sie einerseits um eine sich quer zur Patientenauflage 10 erstreckende Achse Y und andererseits um eine sich längs zur Patientenauflage erstreckende Achse X verschwenkt werden kann. Hierzu ist die Patientenauflage 10 mit der Säule 12 über ein Gelenk 14 verbunden, das zwei Gelenkteile 14A und 14B umfasst, wobei das Gelenk 14 um eine vertikale Drehachse Z in oder entgegen dem Uhrzeigersinn drehbar ist.The patient support 10 is mounted on the column 12 so that it can be pivoted on the one hand about an axis Y extending transversely to the patient support 10 and on the other hand about an axis X extending longitudinally of the patient support. For this purpose, the patient support 10 is connected to the column 12 via a joint 14, which comprises two joint parts 14A and 14B, wherein the joint 14 is rotatable about a vertical axis of rotation Z in or counterclockwise.

Wie beispielsweise Fig. 2 verdeutlicht, ist das Gelenk 14 bei der dargestellten Ausführungsform als Drehschemel ausgebildet, dessen beide Gelenkteile 14A und 14B um eine horizontale Achse S (vgl. Fig. 1) gegeneinander verschwenkbar sind. Hierbei ist die Patientenauflage 10 verdrehbar an dem Gelenkteil 14B befestigt und das Gelenkteil 14A ist verdrehbar an der Säule 12 befestigt. Die Befestigung erfolgt in beiden Fällen mit Hilfe eines Schwenklagers 16A und 16B, was bedeutet, dass die Patientenauflage 10 mit Hilfe des Schwenklagers 16B relativ zu dem Gelenkteil 14B um die Mittelachse des Gelenkteils verschwenkbar ist und dass das Gelenkteil 14A relativ zur Säule 12 um die Mittelachse des Gelenkteils 14A verschwenkbar ist. Als Antrieb für ein Verschwenken des Gelenkteils 14A relativ zur Säule 12 ist ein erster Antriebsmotor 18 vorgesehen, der ortsfest an der Säule 12 befestigt ist und der das Gelenkteil 14A um eine vertikale Achse Z relativ zur Säule 12 verdrehen kann. Weiterhin ist ein zweiter Antriebsmotor 20 vorgesehen, der an der Patientenauflage 10 befestigt ist und der - wie auch der erste Antriebsmotor 18 - über einen Zahntrieb die Patientenauflage 10 relativ zu dem Gelenkteil 14B verschwenkt und zwar um eine Schwenkachse, die sich senkrecht durch den Mittelpunkt des ringförmigen Gelenkteils 14B erstreckt.Like for example Fig. 2 illustrates, the joint 14 is formed in the illustrated embodiment as a turntable, the two hinge parts 14A and 14B about a horizontal axis S (see. Fig. 1 ) are mutually pivotable. Here, the patient support 10 is rotatably mounted on the hinge part 14 B and the hinge part 14 A is rotatably attached to the column 12. The attachment in both cases by means of a pivot bearing 16A and 16B, which means that the patient support 10 with the aid of the pivot bearing 16B relative to the hinge part 14B is pivotable about the central axis of the hinge part and that the hinge part 14A relative to the column 12 about the central axis of the joint part 14A is pivotable. As drive for a pivoting of the joint part 14A relative to the column 12, a first drive motor 18 is provided, which is fixedly attached to the column 12 and which can rotate the joint part 14A about a vertical axis Z relative to the column 12. Furthermore, a second drive motor 20 is provided, which is attached to the patient support 10 and the - like the first drive motor 18 - via a pinion, the patient support 10 pivoted relative to the hinge part 14B about a pivot axis perpendicular to the center of the annular joint part 14B extends.

Mit der oben beschriebenen Konstruktion, bei der die Schwenkachse S des Gelenks 14 exzentrisch zur Mittelachse der Säule 12 und exzentrisch zur Mitte der Patientenauflage 10 angeordnet ist, kann das Gelenk 14 zwischen der Säule 12 und der Patientenauflage 10 um die vertikale Drehachse Z verdreht werden, ohne dass sich die Lage der Patientenauflage 10 relativ zur Säule 12 verändert. Hierzu müssen - ausgehend von der in Fig. 1 dargestellten Nullstellung - die beiden Antriebsmotoren 18 und 20 synchronisiert so angetrieben werden, dass diese eine gegenläufige Drehbewegung im Bereich der Schwenklager 16A und 16B bewirken, so dass sich die Relativposition zwischen Säule 12 und Patientenauflage 10 nicht ändert, jedoch das Gelenk 14 zwischen der stationären Säule 12 und der ihre Position nicht verändernden Patientenauflage 10 hindurchgedreht wird.With the construction described above, in which the pivot axis S of the joint 14 is arranged eccentric to the center axis of the column 12 and eccentric to the center of the patient support 10, the joint 14 between the column 12 and the patient support 10 can be rotated about the vertical axis of rotation Z, without changing the position of the patient support 10 relative to the column 12. For this purpose - starting from the in Fig. 1 illustrated zero position - the two drive motors 18 and 20 are synchronized so driven that they cause an opposite rotational movement in the region of the pivot bearings 16A and 16B, so that the relative position between the column 12 and patient support 10 does not change, but the joint 14 between the stationary column 12 and the position of the patient pad 10 that does not change its position is turned through.

Um die Neigung der Patientenauflage 10 zu verändern, ist ein einziger Hubzylinder 22 vorgesehen, dessen unteres Ende um eine horizontale Achse verschwenkbar an der stationären Säule 12 angelenkt ist und dessen Kolbenstange sich durch die von dem Gelenkteil 14A gebildete Kreis-öffnung hindurch erstrecken kann. Das obere Ende der Kolbenstange des Hubzylinders 22 ist über ein Kugelgelenk 24 mit der Grundplatte 11 der Patientenauflage 10 verbunden, so dass durch Betätigen des Hubzylinders 22 ein Verschwenken der Patientenauflage 10 um die stets horizontal orientierte Schwenkachse S des Gelenks 14 erreicht werden kann.In order to change the inclination of the patient support 10, a single lifting cylinder 22 is provided, the lower end of which is pivoted about a horizontal axis to the stationary column 12 and the piston rod can extend through the circular opening formed by the hinge part 14A. The upper end of the piston rod of the lifting cylinder 22 is connected via a ball joint 24 with the base plate 11 of the patient support 10, so that pivoting of the patient support 10 can be achieved by operating the lifting cylinder 22 about the always horizontally oriented pivot axis S of the joint 14.

Bei der dargestellten Ausführungsform ist sowohl die Patientenauflage 10 um 360° um das Gelenkteil 14B drehbar und das Gelenkteil 14A und somit auch das gesamte Gelenk 14 ist um 360° um die vertikale Drehachse Z drehbar, wobei in beiden Fällen die Drehung in und entgegen dem Uhrzeigersinn erfolgen kann.In the illustrated embodiment, both the patient support 10 is rotatable through 360 ° about the hinge part 14B and the hinge part 14A and thus also the entire hinge 14 is rotatable 360 ° about the vertical axis of rotation Z, in both cases the rotation in and counterclockwise can be done.

Nachfolgend wird anhand der Figuren beschrieben, wie die gewünschten Schwenkstellungen erzielt werden können.In the following, it will be described with reference to the figures how the desired pivot positions can be achieved.

Ausgehend von der in Fig. 1 dargestellten Nullstellung, bei der die Grundplatte 11 der Patientenauflage 10 in der Horizontalen angeordnet ist und die beiden Gelenkteile 14A und 14B nicht gegeneinander verschwenkt sind, kann die Patientenauflage 10 in die Stellung Neigung Fuß-tief (Reverse Trend) gebracht werden, indem das Gelenk 14 so wie in Fig. 1 dargestellt in Richtung des Fußendes der Patientenauflage verdreht wird, bis die Gelenkachse S parallel zur Querachse Y verläuft. Anschließend kann durch Betätigen des Hubzylinders 22 die Patientenauflage 10 um die Schwenkachse S verschwenkt werden und dies so weit, bis eine Schwenkposition von bis zu 90° erreicht wird.Starting from the in Fig. 1 illustrated zero position, in which the base plate 11 of the patient support 10 is arranged in the horizontal and the two joint parts 14A and 14B are not pivoted against each other, the patient support 10 can be brought into the position inclination foot-deep (reverse trend) by the joint 14th as in Fig. 1 is rotated in the direction of the foot end of the patient support until the hinge axis S is parallel to the transverse axis Y. Subsequently, by pressing the lifting cylinder 22, the patient support 10 to the Swivel axis S are pivoted and this until a pivoting position of up to 90 ° is reached.

Wiederum ausgehend von der Nullstellung von Fig. 1 kann eine Linkskantung (Tilt) der Patientenauflage 10, d.h. ein Verschwenken um die Schwenkachse X erreicht werden, indem das Gelenk 14 um die Drehachse Z entgegen dem Uhrzeigersinn um 90° verschwenkt wird, bis die Schwenkachse S parallel zur Achse X bzw. parallel zur Seitenwange 13 verläuft. Ausgehend von dieser in Fig. 3 dargestellten Position kann wiederum durch Betätigen des Hubzylinders 22 ein Verschwenken der Patientenauflage 10 um die Längsachse X erreicht werden, so dass auch Schwenkwinkel von bis zu 90° möglich sind.Again starting from the zero position of Fig. 1 a left tilt (tilt) of the patient support 10, ie a pivoting about the pivot axis X can be achieved by the hinge 14 is pivoted about the rotation axis Z counterclockwise by 90 ° until the pivot axis S parallel to the axis X or parallel to the side wall 13 runs. Starting from this in Fig. 3 shown position can be achieved by actuation of the lifting cylinder 22, a pivoting of the patient support 10 about the longitudinal axis X, so that pivoting angle of up to 90 ° are possible.

Ein Verschwenken der Patientenauflage in die Position Neigung Kopf-tief (Trend) lässt sich entsprechend Fig. 4 dadurch erzielen, dass sich ausgehend von der Nullstellung von Fig. 1 das Gelenk 14 um 180° um die Achse Z verschwenkt wird, so dass dieses in Richtung des Kopfendes der Patientenauflage weist, bevor der Hubzylinder 22 betätigt wird.Swiveling the patient support into the position inclination head-deep (trend) can be adjusted accordingly Fig. 4 Achieve that, starting from the zero position of Fig. 1 the joint 14 is pivoted through 180 ° about the axis Z, so that this points in the direction of the head end of the patient support before the lifting cylinder 22 is actuated.

Schließlich zeigt Fig. 5 ein Verschwenken der Patientenauflage als Rechtskantung (Tilt), wobei hier das Gelenk 14 verglichen zu Fig. 1 um 90° im Uhrzeigersinn (in Draufsicht) verschwenkt worden ist.Finally shows Fig. 5 a pivoting of the patient support as Rechtskantung (tilt), in which case the joint 14 compared to Fig. 1 has been pivoted by 90 ° clockwise (in plan view).

Neben den in den vorstehend beschriebenen Figuren dargestellten Positionen sind selbstverständlich auch sämtliche Zwischenstellungen möglich, so dass die Patientenauflage in jede gewünschte Stellung bewegt werden kann, indem die Antriebsmotoren 18 oder 20 und der Hubzylinder 22 entsprechend betätigt werden. Hierbei versteht es sich, dass der Hubzylinder elektrisch, hydraulisch oder auch pneumatisch betätigt werden kann und dass unter einem Hubzylinder im Sinne der vorliegenden Anmeldung jegliche lineare Stelleinrichtung verstanden wird, mit der die Patientenauflage um das Gelenk 14 verschwenkt werden kann. Alternativ ist es möglich, anstelle des Hubzylinders einen elektrischen oder hydraulischen Direktantrieb vorzusehen, beispielsweise einen Elektromotor im Bereich des Gelenks 14, der die beiden Gelenkteile gegeneinander verschwenkt.In addition to the positions shown in the figures described above, of course, all intermediate positions are possible, so that the patient support can be moved to any desired position by the drive motors 18 or 20 and the lifting cylinder 22 are operated accordingly. It is understood that the lifting cylinder can be operated electrically, hydraulically or pneumatically and that under a lifting cylinder in the context of the present application any linear actuator is understood, with the patient support can be pivoted about the joint 14. Alternatively, it is possible to provide an electric or hydraulic direct drive instead of the lifting cylinder, for example, an electric motor in the region of the joint 14, which pivots the two joint parts against each other.
