Description

Die Erfindung betrifft einen Verbindungsmodul zur Übertragung von elektrischer Energie und/oder Informationssignalen zwischen einer Patientenlagerfläche eines Operationstisches und einer mit der Lagerfläche lösbar verbindbaren Stützeinrichtung, umfassend ein stützeinrichtungsseitiges Modulteil und ein lagerflächenseitiges Modulteil.The invention relates to a connection module for transmitting electrical energy and / or information signals between a patient support surface of an operating table and a support device which can be detachably connected to the support surface, comprising a module part on the support device side and a module part on the storage surface side.

Die Patientenlagerfläche eines Operationstisches besteht aus verschiedenen Abschnitten, die relativ zueinander verstellbar sind. Die Verstellung erfolgt mit Hilfe von Motoren, die in den Holmen der Lagerfläche angeordnet sein können. Die Patientenlagerfläche ist von der Stützeinrichtung des Operationstisches abhebbar und kann beispielsweise auf einen Transportwagen aufgelegt werden. Auch in dieser Situation soll es möglich sein, die Abschnitte der Lagerfläche zu verstellen. Somit kann beispielsweise ein Patient außerhalb des Operationssaales bereits auf die Operation vorbereitet und in eine für die Operation erforderliche Stellung gebracht werden. Für die Verstellung der Abschnitte der Lagerplatte ist die Zufuhr von Energie zu den Stellmotoren der Lagerfläche und der Austausch von Informationssignalen zwischen einer Steuerelektronik innerhalb der Lagerfläche und der Stützeinrichtung erforderlich. Dabei soll die Möglichkeit bestehen, die Lagerfläche beispielsweise in zwei um 180° gegeneinander versetzten Stellungen relativ zur Stützeinrichtung auf dieser anzuordnen. Grundsätzlich kann eine solche Verbindung durch Kabel und Steckverbinder hergestellt werden. Steckverbindungen und Kabel sind aber umständlich zu bedienen und schlecht zu reinigen.The patient support surface of an operating table consists of different sections that are adjustable relative to each other. The adjustment is carried out with the help of motors which can be arranged in the spars of the bearing surface. The patient support surface can be lifted off the support device of the operating table and can be placed on a transport trolley, for example. In this situation, too, it should be possible to adjust the sections of the bearing surface. Thus, for example, a patient outside the operating room are already prepared for the operation and brought into a position required for the operation. The adjustment of the sections of the bearing plate requires the supply of energy to the actuators of the bearing surface and the exchange of information signals between control electronics within the bearing surface and the support device. It should be possible to arrange the bearing surface on the support device, for example in two positions offset by 180 ° relative to one another. In principle, such a connection can be established using cables and connectors. Plug connections and cables are cumbersome to use and difficult to clean.

Der Erfindung liegt die Aufgabe zugrunde, einen Verbindungsmodul der eingangs genannten Art anzugeben, der die Herstellung einer Verbindung zur Übertragung von elektrischer Energie und/oder Informationssignalen auf einfache und bequeme Weise auch für unterschiedliche Stellungen der Patientenlagerfläche relativ zur Stützeinrichtung ermöglicht.The invention has for its object to provide a connection module of the type mentioned, which enables the establishment of a connection for the transmission of electrical energy and / or information signals in a simple and convenient manner for different positions of the patient support surface relative to the support device.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Durch die erfindungsgemäße Zusammenfassung der Übertragungselemente kann die Patientenlagerfläche zumindest in zwei verschiedenen Stellungen, beispielsweise in zwei um 180° gegeneinander versetzten Stellungen mit der Stützeinrichtung verbunden und gleichzeitig eine Verbindung zur Energie- und Signalübertragung mit stationär angeordneten Übertragungselementen hergestellt werden. So können beispielsweise die Übertragungselemente zur Übertragung von elektrischer Energie von metallischen Kontaktelementen gebildet sein, die beim Aufsetzen der Patientenlagerfläche auf die Stützeinrichtung miteinander in Kontakt treten. Ferner können die Übertragungselemente für die Informationssignale für eine berührungslose Übertragung ausgebildet sein, indem sie beispielsweise die Informationssignale in Form von elektromagnetischer Strahlung übertragen. So können in dem einen Modulteil beispielsweise Infrarotsender und in dem anderen Modulteil entsprechende Infrarotempfänger angeordnet sein. Es können jedoch auch Optokoppler verwendet werden, die im sichtbaren Bereich des Spektrums arbeiten. Solche Übertragungselemente zur Übertragung von Informationssignalen können hinter einem für die jeweilige Strahlung transparenten Material angeordnet werden, das eine vollkommen glatte Oberfläche bietet und leicht zu reinigen ist. In diesem Material können auch die metallischen Kontaktelemente zur Übertragung der elektrischen Antriebsenergie für die Stellmotoren innerhalb der Patientenlagerfläche eingebettet sein. Dabei kann es zweckmäßig sein, die Kontaktelemente in dem einen Modulteil beweglich zu machen und sie in Richtung auf die in dem anderen Modulteil angeordneten feststehenden Kontaktelemente vorzuspannen, so daß eine sichere Kontaktgabe beim Zusammentreten der beiden Modulteile gewährleistet ist.By combining the transmission elements according to the invention, the patient support surface can be connected to the support device at least in two different positions, for example in two positions offset by 180 °, and at the same time a connection can be established for energy and signal transmission with stationary transmission elements. For example, the transmission elements for the transmission of electrical energy can be formed by metallic contact elements which come into contact with one another when the patient support surface is placed on the support device. Furthermore, the transmission elements for the information signals can be designed for non-contact transmission, for example by the information signals in the form of electromagnetic radiation transfer. For example, infrared transmitters can be arranged in one module part and corresponding infrared receivers can be arranged in the other module part. However, optocouplers that operate in the visible region of the spectrum can also be used. Such transmission elements for the transmission of information signals can be arranged behind a material which is transparent to the respective radiation and which has a completely smooth surface and is easy to clean. The metallic contact elements for transmitting the electrical drive energy for the servomotors can also be embedded in this material within the patient support surface. It may be expedient to make the contact elements movable in one module part and to pretension them in the direction of the fixed contact elements arranged in the other module part, so that reliable contact is ensured when the two module parts come together.

Vorzugsweise ist die erste Gruppe von Übertragungselementen in der Patientenlagerfläche angeordnet, während die zweite und dritte Gruppe der Übertragungselemente in der Stützeinrichtung vorgesehen ist. Diese kann sowohl von der Stützsäule eines Operationstisches als auch von einem Transportwagen für die Patientenlagerfläche gebildet sein.The first group of transmission elements is preferably arranged in the patient support surface, while the second and third group of transmission elements is provided in the support device. This can be formed both by the support column of an operating table and by a transport trolley for the patient support surface.

Mit der Kopfplatte 14 ist eine allgemein mit 16 bezeichnete Patientenlagerfläche verbunden, von der die Auflagepolster entfernt wurden. Die Patientenlagerfläche 16 umfaßt ein allgemein mit 18 bezeichnetes Mittelteil mit einer rechteckigen Basisplatte 20. Diese ist an zwei einander gegenüberliegenden Rechteckseiten jeweils mit einer Klinke 22 verbunden (von denen in Figur 1 nur eine zu sehen ist), die in entsprechende Aufnahmen 24 an der Kopfplatte 14 der Stützsäule 10 eingreifen, wenn die Patientenlagerfläche 16 auf der Stützsäule 10 verankert wird.In Figure 1, 10 denotes the support column of an operating table, which rests on a column base 12 and has a head plate 14. Connected to the head plate 14 is a patient support surface, generally designated 16, from which the support pads have been removed. The patient support surface 16 comprises a central part, generally designated 18, with a rectangular base plate 20. This is connected on two opposite sides of the rectangle with a pawl 22 (only one of which can be seen in FIG. 1), which in corresponding receptacles 24 on the head plate 14 of the support column 10 engage when the patient support surface 16 is anchored on the support column 10.

Auf der Basisplatte 20 ist ein H-förmiges Rahmenteil 26 angeordnet, das in Richtung des Doppelpfeiles A in Figur 1 relativ zur Basisplatte 20 verstellt werden kann und aus zwei Seitenholmen 28 und einem diese verbindenden Mittelsteg 30 besteht. An den Enden der Seitenholme 28 sind jeweils die Seitenholme 32 weiterer Lagerflächenabschnitte angelenkt, so daß sie um horizontale Querachsen 34 verstellbar sind. Die Verstellung erfolgt mit Hilfe von Motoren 36, die im vorliegenden Fall als Elektromotoren ausgebildet sind. Innerhalb der Basisplatte 20 ist eine nicht dargestellte Steuereinheit angeordnet. Die Übertragung der elektrischen Antriebsenergie zu den Elektromotoren 36 und die Übertragung von Informationssignalen zwischen den Elektromotoren 36 und gegebenenfalls Positionsmeldern innerhalb der Lagerflächenabschnitte und der in der Basisplatte 20 angeordneten Steuereinheit erfolgt über ein Kabel 38, das die Basisplatte 20 mit dem Quersteg 30 verbindet.An H-shaped frame part 26 is arranged on the base plate 20, which can be adjusted in the direction of the double arrow A in FIG. 1 relative to the base plate 20 and consists of two side rails 28 and a central web 30 connecting them. At the ends of the side members 28, the side members 32 of further bearing surface sections are articulated so that they can be adjusted about horizontal transverse axes 34.

Diese Sende-/Empfangselemente (Infrarotdioden) greifen in Ausnehmungen 74 in der Platte 46, 52, die aus einem für die Infrarotstrahlung transparenten Material besteht. Diese Dioden sind über ein Kabel 76 an eine nicht dargestellte Steuereinrichtung angeschlossen. Während die drei Kontaktelemente 60 zur Übertragung von elektrischer Energie für die Antriebsmotoren 36 in der Lagerfläche 16 dienen, erfolgt über die Infrarotdioden 72 das Senden und Empfangen von Informationssignalen. Dabei sind die Kontaktelemente 60 und die Infrarotdioden 72 so geschaltet, daß die in der Figur 2 linken vier Dioden 72 und die beiden linken Kontaktelemente 60 einerseits und die in der Figur 2 rechten vier Dioden und die beiden rechten Kontaktelemente 60 andererseits jeweils zwei völlig gleichartige Gruppen von Übertragungselemente zur Übertragung von elektrischer Antriebsenergie (Kontaktelemente 60) und Informationssignalen (Infrarotdioden 72) bilden. Die vorstehende Beschreibung zeigt darüber hinaus, daß die Oberfläche des säulenseitigen Kontaktmoduls 42 vollkommen dicht und glatt ist, so daß diese Oberfläche auch mit flüssigen Reinigungsmitteln abgewaschen werden kann und keine Winkel oder Vertiefungen hat, in denen sich Schmutz ablagern könnte.Below the plate 46, 52, a circuit board 68 is fastened on stud bolts 70, each of which carries four infrared transmitting / receiving elements 72 in two rows. These transmitting / receiving elements (infrared diodes) engage in recesses 74 in the plate 46, 52, which consists of a material transparent to the infrared radiation. These diodes are connected via a cable 76 to a control device, not shown. While the three contact elements 60 for the transmission of electrical energy for the drive motors 36 in the storage area 16, information signals are sent and received via the infrared diodes 72. The contact elements 60 and the infrared diodes 72 are connected such that the four diodes 72 on the left in FIG. 2 and the two left contact elements 60 on the one hand and the four diodes on the right in FIG. 2 and the two right contact elements 60 on the other hand each have two completely identical groups form transmission elements for the transmission of electrical drive energy (contact elements 60) and information signals (infrared diodes 72). The above description also shows that the surface of the column-side contact module 42 is completely tight and smooth, so that this surface can also be washed off with liquid cleaning agents and has no angles or depressions in which dirt could be deposited.

Das lagerflächenseitige Modulteil 44 ist im Prinzip genauso aufgebaut, wie das säulenseitige Modulteil 42, enthält jedoch weniger Übertragungselemente und ist daher auch kleiner. Es besteht aus einer Platte mit einem Mittelabschnitt 78 und einem diesen umgebenden Flansch 80, der mit Schrauben 82 an einer Bodenplatte 84 des Basisteils 20 angeschraubt ist, wobei die Verbindung wiederum durch einen Dichtring 86 abgedichtet ist. In dem Mittelabschnitt 78 sind in Gegenüberstellung zu den in Figur 2 rechten beiden Kontaktelementen 60 zwei bewegliche Kontaktelemente 88 gelagert. Jedes bewegliche Kontaktelement 88 ist in einer Bohrung 90 geführt und wird durch eine Ringfeder 92 in der dargestellten Weise in Richtung auf das jeweilige feste Kontaktelement 60 des Modulteils 42 vorgespannt. Die Austrittsöffnung der Bohrung 90 ist durch eine Dichtmanschette 94 flüssigkeitsdicht abgeschlossen. Die Kontaktelemente 88 sind über Leitungen 96 mit einer nicht dargestellten Steuereinrichtung bzw. einem Verteiler für die elektrische Antriebsenergie verbunden.The module part 44 on the bearing surface is in principle constructed in exactly the same way as the column-side module part 42, but contains fewer transmission elements and is therefore also smaller. It consists of a plate with a central section 78 and a flange 80 surrounding the latter, which is screwed to a base plate 84 of the base part 20 with screws 82, the connection in turn being sealed by a sealing ring 86. In contrast to the two contact elements 60 on the right in FIG. 2, two movable contact elements 88 are mounted in the central section 78. Each movable contact element 88 is guided in a bore 90 and is biased by an annular spring 92 in the manner shown in the direction of the respective fixed contact element 60 of the module part 42. The outlet opening of the bore 90 is closed in a liquid-tight manner by a sealing collar 94. The contact elements 88 are connected via lines 96 to a control device or a distributor for the electrical drive energy, not shown.

In dem lagerflächenseitigen Modulteil 44 sind ferner vier Infrarotdioden 98 so angeordnet, daß sie der in der Figur 2 rechts gelegenen Vierergruppe von Infrarotdioden 72 genau gegegenüberliegen. Sie sind auf einer Platine 100 angeordnet, die mit der Steuereinrichtung verbunden ist. Auch die Platte des lagerflächenseitigen Modulteils 44 ist so in die Bodenplatte 84 des Basisteils 20 eingesetzt, daß die Unterseite der Bodenplatte 84 vollkommen eben ist. Aus dieser Bodenplatte können nur die Spitzen der beweglichen Kontaktelemente heraustreten.In the module part 44 on the bearing surface, four infrared diodes 98 are further arranged so that they are exactly opposite the group of four of infrared diodes 72 located on the right in FIG. They are arranged on a circuit board 100 which is connected to the control device. The plate of the module part 44 on the bearing surface is also inserted into the base plate 84 of the base part 20 such that the underside of the base plate 84 is completely flat. Only the tips of the movable contact elements can emerge from this base plate.

Wie man erkennt, sind die beiden Modulteile 42 und 44 so ausgebildet und angeordnet, daß die beiden Modulteile 42 und 44 in zwei um 180° gegeneinander versetzten Stellungen miteinander verbunden werden können. In der einen in Figur 3 dargestellten Stellung wirken die beweglichen Kontaktelemente 88 und die vier Infrarotdioden 98 des lagerflächenseitigen Modulteiles (erste Gruppe von Übertragungselementen) mit den in der Figur 2 rechten beiden Kontaktelementen 60 und der rechten Vierergruppe von Infrarotdioden 72 (zweite Gruppe von Übertragungselementen) zusammen. Wird die Lagerfläche 16 relativ zur Stützsäule 10 und damit auch das lagerflächenseitige Modulteil 44 relativ zum säulenseitigen Modulteil 42 um 180° gedreht, dann wirkt die erste Gruppe von Übertragungselementen mit den in der Figur 2 dargestellten linken beiden Kontaktelementen 60 bzw. der linken Vierergruppe von Infrarotdioden 72 (dritte Gruppe von Übertragungselementen) zusammen.As can be seen, the two module parts 42 and 44 are designed and arranged such that the two module parts 42 and 44 can be connected to one another in two positions offset by 180 °. In the position shown in FIG. 3, the movable contact elements 88 and the four infrared diodes 98 of the module part on the bearing surface (first group of transmission elements) act with the two contact elements 60 on the right in FIG. 2 and the right group of four of infrared diodes 72 (second group of transmission elements) together. If the bearing surface 16 is rotated 180 ° relative to the support column 10 and thus also the bearing surface-side module part 44 relative to the column-side module part 42, then the first group of transmission elements acts with the left two contact elements 60 shown in FIG. 2 or the left group of four of infrared diodes 72 (third group of transmission elements) together.

Die vorstehende Beschreibung zeigt, daß der erfindungsgemäße Verbindungsmodul eine Verbindung zur Übertragung von elektrischer Antriebsenergie und von Informationssignalen zwischen der Stützsäule und der Patientenlagerfläche in zwei verschiedenen Stellungen der Lagerfläche relativ zur Stützsäule ermöglicht, wobei die lagerflächenseitigen Übertragungselemente und die säulenseitigen Übertragungselemente beim Aufsetzen der Lagerfläche auf die Stützsäule in Übertragungsverbindung treten und wobei beide Modulteile so in die Stützsäule bzw. die Lagerfläche eingebaut sind, daß ihre Oberflächen problemlos gereinigt werden können und keine Möglichkeit für das Festsetzen von Schmutz bieten. Der säulenseitige Modulteil kann auch an einem Transportwagen zum Transport der Patientenlagerfläche vorgesehen sein, um die Patientenlagerfläche auch außerhalb des Operationssaales mit der für die Verstellung der Motoren erforderlichen Energie und Steuerinformation zu versorgen.The above description shows that the connection module according to the invention enables a connection for the transmission of electrical drive energy and information signals between the support column and the patient support surface in two different positions of the support surface relative to the support column, the transmission surface-side transmission elements and the column-side transmission elements when the bearing surface is placed on the Support column in transmission connection and with both module parts like this are built into the support column or the bearing surface so that their surfaces can be cleaned without problems and offer no possibility for dirt to settle. The column-side module part can also be provided on a transport trolley for transporting the patient support area in order to supply the patient support area outside of the operating room with the energy and control information required for adjusting the motors.
