- the control unit 52 changes from the first operating mode to a second operating mode, which serves as a power-saving mode and in which the drive unit 41 and the first sensor unit are deactivated.
- the first sensor unit is also referred to as a position sensor unit.
- a second sensor unit for monitoring the change in the adjustment position of the component 40 is activated.
- the structure and function of this second sensor unit will be described below in connection with FIG. 2 explained in more detail.
- FIG. 2 shows a section of the drive unit 41 for height adjustment of the operating table column 40 of the operating table 30 after the FIGS. 1a to 1c .
- the drive unit 41 comprises an electric motor 70, to the output shaft 71 of which a first gear 72 is connected.

- the detection of the length of the operating table column 40 or the height of a patient support surface 31 connected to the operating table column 40 is effected by means of a position sensor unit 86 serving as a sensor unit.
- the position sensor unit 86 is connected to the control unit 52 via a signal line.
- the control unit 52 evaluates the sensor signals of the position sensor unit 86.
- the drive unit 41 comprises a second sensor unit 90 designed as a reed switch 90, which changes its switching state, ie its signal state, that of a depending on the position of arranged on the peripheral surface of a flange of the gear 72 at an angular distance of 90 ° magnet 82a to 82d Monitoring circuit 84 of the control unit 52 is evaluated.
- a rotation of the threaded spindle 78 takes place in the direction of the arrow P7, so that the magnet 82d is arranged opposite the sensor unit 90, as shown in FIG FIG. 3 is shown.
- the first sensor unit can also be designed as an incremental encoder which detects the rotation of the threaded spindle 78.
- the position sensor unit 86 is active in the first operating mode of the control unit 52.
- the second mode of operation which is a power saving mode of the operating table 30
- both the electric motor 70 and the position sensor unit 86 are deactivated.
- only the control function of the control circuit 84 of the control unit 52 is active, which detects a change in the switching state of the reed switch 90 in the second operating mode.
- the control circuit 84 of the control unit 52 detects operating inputs via the remote control 12, wherein the control circuit 84 causes a change of the operating mode of the control unit 52 from the second operating mode to the first operating mode, if in the second operating mode, a change of the switching state of the reed switch 90 or an operating input via the Remote control 12 takes place.
- the position sensor unit 86 is continuously activated so that an active height control of the patient support surface 31 takes place.
- position correction is performed by suitable driving of the electric motor 70.
- the electric motor 70 comprises a brake unit which exerts a braking force on the output shaft 71 of the electric motor 70 in the currentless state and thus on the output shaft 71 of the electric motor 70. This prevents a change in position of the coupling element 80 when the electric motor 70 is deactivated. In the case of a defect in this brake unit, however, the position of the coupling element 80 may change, in particular due to the weight of the patient support surface 31 and of the patient lying thereon. Such a change in position caused by a fault of the brake is then detected by means of the reed switch 90 in conjunction with the magnets 82a to 82d.
- FIG. 4 a block diagram of the drive unit 41 is shown.
- the control unit 52 supplies the position sensor unit 86 with a supply voltage and preferably receives as a sensor signal from the position sensor unit 86 a binary signal, which is evaluated by means of the position detection function 92 of the control unit 52 .
- the brake control function 94 the brake of the motor 70 and driven by the motor drive function 96 of the motor 70 so that it causes the desired rotation of the gear 72.
- the control functions 92 to 96 and possibly further control functions are activated in the first operating mode and deactivated in the second operating mode, ie in the energy-saving mode.
- the control function 84 of the control unit 52 is activated via the voltage supply of the accumulator 53, so that the reed switch 90 is supplied with voltage.
- control circuit 84 Upon detection of the change in the switching state of the reed switch 90 by means of the control circuit 84, this causes a change in the operating mode of the control unit 52 from the second operating mode to the first operating mode in which the control functions 92 to 96 are reactivated. Furthermore, the control circuit 84 includes the evaluation of the signals of a transmitting and / or receiving unit 98 for receiving operating information sent via the remote control 12. Upon receiving such operation information, the control mode 84 also changes the operation mode of the control unit 52 from the second operation mode to the first operation mode.
- the change of the operating mode from the first operating mode to the second operating mode takes place when no operating information has been sent from the remote control 12 to the transmitting / receiving unit 98 for a preset period of time.
- the drive unit 41 has an error when a change in the switching state of the reed switch 90 is detected in the second operating mode. From this, the first mode of operation is then retained to provide the safe one Operation of the operating table 30 and the associated safe conduct of an operation to ensure.
- Reed switches 90 which are also referred to as reed contacts, can be embodied as contact tongues melted into a glass tube. These contact tongues may in particular have an iron-nickel alloy, so that the contact tongues are magnetically actuated. By arranging the contact tongues in a glass tube, reed switches are hermetically sealed switches that are actuated by a magnetic field. The contact tongues must have at least in a partial area ferromagnetic material. Such Reedschalter 90 have a small size compared to conventional contacts and make it possible to perform fast switching operations. Reed switch 90 can be designed as a normally closed, normally open or changeover or changeover switch.
- One or more magnets 82a to 82d are fixed to an axis rotatable member such as a sprocket 72, a gear or a shaft within a drive train of the drive unit 41 of the operating table 30.
- an axis rotatable member such as a sprocket 72, a gear or a shaft within a drive train of the drive unit 41 of the operating table 30.
- the magnet or the magnets 82a to 82d are guided past a reed switch 90.
- the change in the switching state of the reed switch 90 and the change in a signal state of the reed switch 90 caused thereby with a corresponding voltage supply of the reed switch 90 can be used as a signal for changing the operating mode from the second operating mode to the first operating mode.
- the position of the drive motor 70 is detected via an incremental encoder in the first operating mode, it can be ensured by the arrangement of the reed switch 90 that a rotation of the rotatable component 72 is detected.
- the mentioned incremental encoders do not indicate an absolute position, but only detect relative position changes, which can be evaluated only with an activated corresponding control function 92 of the control unit 52. If the control function 92 is deactivated in the second operating mode, ie, temporarily, in order to save energy, for example, and if movement of the drive 41 takes place during this period, this movement is not detected by the incremental encoder or is not evaluated by the control unit 52. If a change of the operating mode from the second operating mode to the first operating mode due to a switching operation of the reed switch 90, the control unit 52 is continuously operated in the first operating mode, so that a further malfunction is avoided.

Ferner betrifft die Erfindung ein Verfahren zum Steuern eines solchen Operationstischs.The invention relates to an operating table which has at least one adjustable by means of an electric drive unit component. The operating table has a first sensor unit for detecting the adjustment position and / or changing the adjustment position of the component. Furthermore, the invention relates to a method for controlling such an operating table.
Im Krankenhausbetrieb werden üblicherweise drei unterschiedliche Arten von Operationstischen eingesetzt, nämlich stationäre Operationstische, bewegbare Operationstische und mobile Operationstische. Stationäre Operationstische haben eine fest mit dem Fußboden des Operationssaals verbundene Operationstischsäule, wobei sie üblicherweise keinen Operationstischfuß haben und über festinstallierte Kabel mit Energie versorgt werden.In hospital operations, three different types of operating tables are commonly used, namely stationary operating tables, movable operating tables and mobile operating tables. Stationary operating tables have an operating table column fixed to the floor of the operating room, and usually have no operating table base and are powered by permanently installed cables.
Bewegbare Operationstische haben einen mit der Operationstischsäule verbundenen Operationstischsäulefuß, der keine Rollen und keine Transportmittel aufweist und zumindest bei einer Operation auf dem Fußboden des Operationssaals steht. Die bewegbaren Operationstische sind mithilfe von Transportwagen anhebbar und verfahrbar. Ein solches System, das einen bewegbaren Operationstisch und einen Transportwagen umfasst, wird auch als mobiles Operationstischsystem bezeichnet.Movable operating tables have an operating table column foot connected to the operating table column, which has no rollers and no transport means and at least stands on the floor of the operating room during an operation. The movable operating tables can be raised and moved by means of transport trolleys. Such a system comprising a movable operating table and a trolley is also referred to as a mobile operating table system.
Operationstischsäulenfüße mobiler Operationstische haben Rollen zum Verfahren des Operationstischs, so dass sie ohne zusätzliche Hilfsmittel verfahrbar sind. Bei mobilen Operationstischen können ferner elektrische Fahrantriebe, vorzugsweise mit Sanftanlauf und Sicherheitsbremsfunktion, eingesetzt werden, um den mobilen Operationstisch mithilfe des elektrischen Fahrantriebs zu verfahren.Operating table column feet Mobile operating tables have rollers for operating the operating table so that they can be moved without additional aids. In mobile operating tables electric traction drives, preferably with soft start and safety brake function, can also be used to move the mobile operating table using the electric traction drive.
Die Energieversorgung der bewegbaren Operationstische und der mobilen Operationstische kann über Akkumulatoren erfolgen, die vorzugsweise im Operationstisch integriert sind, vorzugsweise in dem Operationstischsäulenfuß oder in der Operationstischsäule angeordnet sind.The power supply of the movable operating tables and the mobile operating tables can be effected via accumulators, which are preferably integrated in the operating table, preferably arranged in the operating table column foot or in the operating table column.
Sowohl bei stationären Operationstischen als auch bei bewegbaren Operationstischen und mobilen Operationstischen können elektromotorisch verstellbare Komponenten vorgesehen sein, wie beispielsweise eine in ihrer Länge elektromotorisch veränderbare Operationstischsäule zur Veränderung der Höhe einer auf der Operationstischsäule angeordneten Patientenlagerfläche, ein um zwei orthogonale Achsen verstellbare Operationstischsäulenkopf zur Veränderung der Neigung bzw. der Kantung der mit dem Operationstischsäulenkopf verbundenen Patientenlagerfläche und/oder elektromotorisch verstellbare Komponenten der Patientenlagerfläche.Both inpatient operating tables and movable operating tables and mobile operating tables may be provided electromotically adjustable components, such as an electromotive modifiable in its length operating table column for changing the height of a arranged on the operating table column patient support surface, a two orthogonal axes adjustable operating table column head to change the inclination or the edging of the patient support surface connected to the operating table column head and / or components of the patient support surface which can be adjusted by an electric motor.
Insbesondere bei Operationstischen, deren Energieversorgung über Akkumulatoren erfolgt, ist es erforderlich Energiesparfunktionen vorzusehen und Sensoren, Aktoren und Steuerfunktionen zu deaktivieren, wenn eine voreingestellte Zeit lang keine Steuerfunktion durch eine Eingabe über ein Bedienelement oder einer anderweitig inizierte Steuerfunktion aktiviert worden ist. Bei längeren Operationen wird oft über lange Zeiträume hinweg die Lage des Patienten beibehalten, so dass in diesen Zeiträumen eine Energiesparfunktion aktiviert werden kann. Werden durch eine solche Energiesparfunktion auch Sensoreinheiten deaktiviert, die selbst einen relevanten Energieverbrauch haben und/oder durch die eine Steuereinheit zur Auswertung der Sensorsignale der Sensoreinheit einen relevanten Energieverbrauch hat, kann das Problem auftreten, dass sich die Verstellposition der Komponente durch externe Krafteinwirkung ändert, insbesondere dann, wenn ein Defekt an einer weiteren Komponente, wie beispielsweise ein Defekt einer Motorbremse, auftritt. Insbesondere kann eine in ihrer Höhe verstellbare Operationstischsäule durch das Gewicht der Patientenlagerfläche und/oder des Patienten absinken. Erfolgt dies bei einer Operation, so besteht die Gefahr, dass ein Arzt beim Durchführen der Operation behindert wird und der Patient gefährdet wird.In particular, in operating tables whose power is supplied by accumulators, it is necessary to provide energy-saving functions and to deactivate sensors, actuators and control functions when no control function has been activated for a preset time by an input via an operating element or otherwise initiated control function. For longer operations, the patient's posture is often maintained over long periods of time, so that an energy-saving feature can be activated during these periods. If sensor units which themselves have a relevant energy consumption and / or through which a control unit for evaluating the sensor signals of the sensor unit has a relevant energy consumption, the problem may arise that the adjustment position of the component changes by external force, in particular when a defect in another component, such as a motor brake fault, occurs. Especially For example, a height adjustable operating table column may fall through the weight of the patient support surface and / or the patient. If this occurs during an operation, there is a risk that a doctor will be hindered in carrying out the operation and the patient is at risk.

Es ist Aufgabe der Erfindung, einen Operationstisch und ein Verfahren zum Steuern eines Operationstischs anzugeben, durch die der Energiebedarf des Operationstischs bei einer Operation reduziert werden kann und durch die eine Gefährdung eines Patienten vermieden wird.It is an object of the invention to provide an operating table and a method for controlling an operating table, by which the energy requirement of the operating table can be reduced during surgery and by which a risk to a patient is avoided.
Diese Aufgabe wird durch einen Operationstisch mit den Merkmalen des Anspruchs 1 sowie durch ein Verfahren zum Steuern eines Operationstischs mit den Merkmalen des unabhängigen Verfahrensanspruchs gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by an operating table having the features of claim 1 and by a method for controlling an operating table having the features of the independent method claim. Advantageous developments of the invention are specified in the dependent claims.
Durch einen Operationstisch mit den Merkmalen des Anspruchs 1 wird im zweiten Betriebsmodus der Steuereinheit, der vorzugsweise ein Energiesparmodus ist, die erste Sensoreinheit deaktiviert und die zweite Sensoreinheit zum Überwachen einer Änderung der Verstellposition der Komponente aktiviert. Im ersten Betriebsmodus der Steuereinheit ist die erste Sensoreinheit aktiviert. Ferner ist im ersten Betriebsmodus die Antriebseinheit zum Verstellen der Komponente mithilfe eines Bedienelements aktivierbar. Die Steuereinheit wechselt vom ersten in den zweiten Betriebsmodus, wenn die Antriebseinheit einen voreingestellten Zeitraum lang nicht aktiviert worden ist. Die Steuereinheit wechselt vom zweiten in den ersten Betriebsmodus, wenn die zweite Sensoreinheit eine Änderung der Verstellposition der Komponente detektiert. Als zweite Sensoreinheit kann dabei eine einfach aufgebaute Sensoreinheit vorgesehen sein, die bei einer Änderung der Verstellposition der Komponente vorzugsweise ein Binärsignal ausgibt. Eine solche Sensoreinheit benötigt keine oder nur wenig Energie. Auch die Auswertung des binären Sensorsignals mit Hilfe der Steuereinheit kann ohne großen Rechenaufwand erfolgen, so dass für die zweite Sensoreinheit und für die Auswertung des Sensorsignals der zweiten Sensoreinheit keine oder nur relativ wenig Energie gegenüber der Aktivierung der ersten Sensoreinheit und der Auswertung des Sensorsignals der ersten Sensoreinheit im ersten Betriebsmodus erforderlich ist. Durch die zweite Sensoreinheit wird jedoch sichergestellt, dass eine Veränderung der Verstellposition der Komponente detektiert wird, wenn die erste Sensoreinheit deaktiviert ist, so dass geeignete Maßnahmen ergriffen werden können, um den Patienten während der Operation nicht zu gefährden.By means of an operating table having the features of claim 1, in the second operating mode of the control unit, which is preferably a power-saving mode, the first sensor unit is deactivated and the second sensor unit is activated to monitor a change in the adjustment position of the component. In the first operating mode of the control unit, the first sensor unit is activated. Furthermore, in the first operating mode, the drive unit for adjusting the component can be activated by means of a control element. The control unit changes from the first to the second operating mode if the drive unit has not been activated for a pre-set period of time. The control unit changes from the second to the first operating mode when the second sensor unit detects a change in the adjustment position of the component. As a second sensor unit can be provided a simply constructed sensor unit, which preferably outputs a binary signal when changing the adjustment position of the component. Such a sensor unit is needed no or little energy. The evaluation of the binary sensor signal with the help of the control unit can be done without much computational effort, so that for the second sensor unit and for the evaluation of the sensor signal of the second sensor unit no or only relatively little energy compared to the activation of the first sensor unit and the evaluation of the sensor signal of the first Sensor unit in the first operating mode is required. However, the second sensor unit ensures that a change in the adjustment position of the component is detected when the first sensor unit is deactivated, so that suitable measures can be taken in order not to endanger the patient during the operation.
Vorzugsweise ist der zweite Betriebsmodus ein Energiesparmodus, in dem die erste Sensoreinheit und/oder zumindest ein Teil der Steuerfunktionen der Steuereinheit deaktiviert sind. Dadurch wird erreicht, dass der Energiebedarf des Operationstischs während einer Operation verringert wird.The second operating mode is preferably a power-saving mode in which the first sensor unit and / or at least part of the control functions of the control unit are deactivated. This ensures that the power requirement of the operating table is reduced during surgery.
Weiter ist es vorteilhaft, wenn der Wert für den voreingestellten Zeitraum durch eine Bedieneingabe über eine Bedieneinheit der Steuereinheit von einem Benutzer auf einen Wert in einem zulässigen voreingestellten Bereich änderbar ist. Diese Bedieneinheit kann insbesondere eine Fernbedienung mit Bedienelementen zur Bedienung des Operationstischs sein. Dadurch kann der Zeitraum, nach dem die Steuereinheit vom ersten Betriebsmodus in den zweiten Betriebsmodus wechselt, auf einfache Art verändert werden, insbesondere an die persönlichen Wünsche eines Operateurs und/oder an den Ablauf einer Operation angepasst werden. Vorzugsweise hat der voreingestellte Zeitraum einen Wert im Bereich von 1 Sekunde bis 1 Stunde, insbesondere von 10 Sekunden bis 10 Minuten. Durch einen voreingestellten Wert in einem dieser angegebenen Bereiche wird erreicht, dass der Operationsablauf durch die Änderung des Betriebsmodus nicht beeinträchtigt wird und während der Operation durch den Wechsel in den zweiten Betriebsmodus Energie gespart werden kann.Further, it is advantageous if the value for the preset period of time can be changed by an operator input via an operating unit of the control unit by a user to a value in a permissible preset range. This operating unit may in particular be a remote control with operating elements for operating the operating table. As a result, the period of time after which the control unit changes from the first operating mode to the second operating mode can be changed in a simple manner, in particular adapted to the personal wishes of an operator and / or to the course of an operation. Preferably, the preset period of time is in the range of 1 second to 1 hour, more preferably 10 seconds to 10 minutes. By a preset value in one of these specified ranges is achieved that the operation sequence through the Changing the operating mode is not affected and during the operation by switching to the second operating mode energy can be saved.
Besonders vorteilhaft ist es, wenn nach einem Wechsel von dem zweiten Betriebsmodus in den ersten Betriebsmodus infolge einer Detektion einer Änderung der Verstellposition der Komponente durch die zweite Sensoreinheit die Steuereinheit auch nach dem Ablauf des voreingestellten Zeitraums im ersten Betriebsmodus verbleibt. Dadurch kann die Verstellposition der Komponente nach einem Wechsel von dem zweiten Betriebsmodus in den ersten Betriebsmodus infolge der Detektion einer Änderung der Verstellposition der Komponente durch die zweite Sensoreinheit im zweiten Betriebsmodus im ersten Betriebsmodus durch die erste Sensoreinheit detektiert und überwacht werden. Die Steuereinheit kann dabei die Antriebseinheit abhängig vom Sensorsignal der ersten Sensoreinheit derart ansteuern, dass eine Kontrolle und erforderlichenfalls eine Korrektur der mithilfe des Bedienelements eingestellten Verstellposition der Komponente vorzugsweise automatisch ohne weitere Bedieneingabe erfolgt. Dadurch erfolgt ein automatisches Entgegenwirken der ungewollten Bewegung durch die Steuereinheit in Verbindung mit der Antriebseinheit. Dies ist insbesondere dann sinnvoll, wenn davon ausgegangen wird, dass mithilfe der zweiten Sensoreinheit ein Fehlerzustand des Operationstischs detektiert wird, da dann durch das Steuern der Antriebseinheit abhängig vom Sensorsignal der ersten Steuereinheit eine ggf. erforderliche Korrektur der über das Bedienelement eingestellten gewünschten Verstellposition der Komponente sichergestellt wird, so dass keine Beeinträchtigung bei der Operation erst recht keine Gefährdung des Patienten auftritt.It is particularly advantageous if, after a change from the second operating mode to the first operating mode as a result of detection of a change in the adjustment position of the component by the second sensor unit, the control unit also remains in the first operating mode after the expiry of the preset time period. As a result, the adjustment position of the component can be detected and monitored by the first sensor unit after a change from the second operating mode to the first operating mode as a result of the detection of a change in the adjustment position of the component by the second sensor unit in the second operating mode in the first operating mode. In this case, the control unit can control the drive unit as a function of the sensor signal of the first sensor unit such that a check and, if necessary, a correction of the adjustment position of the component set using the operating element are preferably carried out automatically without further operator input. This results in an automatic counteracting of the unwanted movement by the control unit in conjunction with the drive unit. This makes sense in particular when it is assumed that an error state of the operating table is detected with the aid of the second sensor unit, since then, by controlling the drive unit as a function of the sensor signal of the first control unit, a possibly required correction of the desired adjustment position of the component set via the operating element is ensured so that no impairment in the operation certainly no danger to the patient occurs.
Ferner ist es vorteilhaft, wenn die Steuereinheit die Schrittpositionsüberwachung eines als Antriebseinheit dienenden Schrittmotors aktiviert und/oder wenn die Steuereinheit die Wicklung eines als Antriebseinheit dienenden Elektromotors kurzschließt. Dadurch kann eine ungewollte Änderung der Verstellposition der Komponente verhindert oder die Änderung der Verstellposition der Komponente verlangsamt werden.Furthermore, it is advantageous if the control unit activates the stepping position monitoring of a stepping motor serving as the drive unit and / or if the control unit short-circuits the winding of an electric motor serving as the drive unit. This can prevent an unwanted change in the adjustment of the component or slowing down the change in the adjustment position of the component.
Besonders vorteilhaft ist es, wenn die Antriebseinheit eine Bremse umfasst, die zumindest im zweiten Betriebsmodus aktiviert ist. Vorzugsweise wird die Bremse mithilfe einer Federkraft aktiviert und mithilfe eines elektrischen Antriebs deaktiviert, so dass die Bremse in einem stromlosen Zustand der Antriebseinheit aktiviert ist und insbesondere eine Drehung einer Ankerwelle eines Elektromotors der Antriebseinheit verhindert. Bei einem Defekt dieser Bremse würde auch im zweiten Betriebsmodus die zweite Sensoreinheit eine Änderung der Verstellposition der Komponente detektieren, so dass ein Defekt der Bremse einfach und sicher mithilfe der zweiten Sensoreinheit detektierbar ist.It is particularly advantageous if the drive unit comprises a brake which is activated at least in the second operating mode. Preferably, the brake is activated by means of a spring force and deactivated by means of an electric drive, so that the brake is activated in a de-energized state of the drive unit and in particular prevents rotation of an armature shaft of an electric motor of the drive unit. In the event of a defect of this brake, the second sensor unit would also detect a change in the adjustment position of the component in the second operating mode so that a defect in the brake can be detected simply and reliably with the aid of the second sensor unit.
Besonders vorteilhaft ist es, wenn die Komponente eine Höhenverstelleinheit, eine Längsneigungsverstelleinheit oder eine Kippneigungsverstelleinheit einer Operationstischsäule ist und wenn die Verstellposition die Höhe einer mit der Operationstischsäule verbundenen Patientenlagerfläche, die Längsneigungsverstellung der Patientenlagerfläche und/oder die Kippneigungsverstellung der Patientenlagerfläche betrifft. Dadurch wird sichergestellt, dass zumindest eine zentrale Verstelloption der Operationstischsäule mithilfe der zweiten Sensoreinheit auch im zweiten Betriebsmodus der Steuereinheit überwacht wird. Als Längsneigungsverstellung wird dabei das Verschwenken der Patientenlagerfläche um eine Drehachse bezeichnet, die orthogonal zur Längsachse der Patientenlagerfläche oder zu einer zur Längsachse der Patientenlagerfläche in derselben senkrechten Ebene verlaufenden parallelen Achse orthogonal ist, in der auch die Längsachse verläuft. Als Kippneigungsverstellung wird ein Verschwenken der Patientenlagerfläche um ihre Längsachse oder um eine zur Längsachse der Patientenlagerfläche in derselben senkrechten Ebene parallel verlaufende Drehachse bezeichnet, in der auch die Längsachse verläuft.It is particularly advantageous if the component is a Höhenverstelleinheit, a Längsneigungsverstelleinheit or Kippneigungsverstelleinheit an operating table column and when the adjustment position relates to the height of a connected to the operating table column patient support surface, the pitch adjustment of the patient support surface and / or the tilt tilt adjustment of the patient support surface. This ensures that at least one central adjustment option of the operating table column is monitored by means of the second sensor unit even in the second operating mode of the control unit. As a pitch adjustment while the pivoting of the patient support surface is referred to an axis of rotation orthogonal to the longitudinal axis of the patient support surface or to a longitudinal axis of the patient support surface in the same vertical plane extending parallel axis orthogonal, in which also runs the longitudinal axis. As a tilting tilt adjustment, a pivoting of the patient support surface about its longitudinal axis or about an axis parallel to the longitudinal axis of the patient support surface in the same plane extending axis of rotation is referred to, in which also runs the longitudinal axis.
Ferner ist es vorteilhaft, wenn die zweite Sensoreinheit mindestens einen Reedschalter umfasst, der eine Rotation einer Abtriebswelle eines als Antriebseinheit dienenden Elektromotors und/oder die Rotation eines mit der Abtriebswelle in Eingriff stehenden Elements detektiert. Insbesondere muss hierzu lediglich ein Permanentmagnet mit der Abtriebswelle des Elektromotors verbunden oder in diese integriert werden bzw. mit dem mit der Abtriebswelle in Eingriff stehenden Element verbunden oder in dieses integriert werden, um mithilfe eines einfachen Reedschalters eine Änderung der Verstellposition der Komponente zu detektieren. Zur Auswertung der zweiten Sensoreinheit muss dann lediglich eine Änderung des Schaltzustandes des Reedschalters überwacht werden. Bei einer Änderung des Schaltzustandes ist von einer Änderung der Verstellposition der Komponente auszugehen, so dass im zweiten Betriebszustand der Steuereinheit von einer Fehlfunktion des Operationstischs ausgegangen werden muss bzw. von einem Fehler einer Baueinheit des Operationstischs. Reedschalter sind sehr robust, kostengünstig und beanspruchen relativ wenig Bauraum.Furthermore, it is advantageous if the second sensor unit comprises at least one reed switch, which detects a rotation of an output shaft of an electric motor serving as drive unit and / or the rotation of an element engaging with the output shaft. In particular, this requires only a permanent magnet to be connected to the output shaft of the electric motor or integrated into this or connected to the output shaft engaging element or integrated into it to detect a change of the adjustment of the component using a simple reed switch. To evaluate the second sensor unit then only a change in the switching state of the reed switch must be monitored. When changing the switching state is to start from a change in the adjustment of the component, so that must be assumed in the second operating state of the control unit of a malfunction of the operating table or a fault of a structural unit of the operating table. Reed switches are very robust, inexpensive and require relatively little space.
Ferner ist es vorteilhaft, wenn der Reedschalter zumindest dann eine Rotation der Abtriebswelle oder des mit der Abtriebswelle in Eingriff stehenden Elements detektiert, wenn eine Rotation der Abtriebswelle oder des mit dieser in Eingriff stehenden Elements um einen vorgegebenen Winkel im Bereich von 1° bis 360°, vorzugsweise im Bereich von 45° bis 90°, erfolgt. Hierdurch kann insbesondere durch die Wahl einer geeigneten Übersetzung bereits eine geringe Änderung der Verstellposition der Komponente detektiert werden, so dass eine Verstellung frühzeitig bemerkt und eine Gefährdung des Patienten verhindert werden kann.Further, it is advantageous if the reed switch at least then detects a rotation of the output shaft or of the output shaft engaging element when a rotation of the output shaft or of the element engaging therewith by a predetermined angle in the range of 1 ° to 360 ° , preferably in the range of 45 ° to 90 °. As a result, a small change in the adjustment position of the component can be detected, in particular by the choice of a suitable translation, so that an adjustment can be detected early and a risk to the patient can be prevented.
Besonders vorteilhaft ist es, wenn das mit der Antriebseinheit in Eingriff stehende Element ein Bauteil eines mit der Antriebseinheit gekoppelten Getriebes ist. Dadurch kann die zweite Sensoreinheit einfach mit einem zum Antrieb der Komponente erforderlichen Bauelements gekoppelt werden und es ist kein Eingriff in den Elektromotor erforderlich, in dem üblicherweise wenig Bauraum zur Verfügung steht. Ferner kann dadurch ein handelsüblicher Elektromotor zum Antrieb verwendet werden, der nicht für die erfindungsgemäße Verwendung speziell angepasst werden muss.It is particularly advantageous if the element engaging with the drive unit is a component of a transmission coupled to the drive unit. Thereby For example, the second sensor unit can simply be coupled to a component required for driving the component, and no intervention in the electric motor is required in which there is usually little space available. Furthermore, a commercially available electric motor can be used for the drive, which does not have to be specially adapted for the use according to the invention.
Ferner ist es vorteilhaft, wenn beim Aktivieren des Bedienelements eine Änderung des Betriebsmodus vom zweiten Betriebsmodus in den ersten Betriebsmodus erfolgt. Hierdurch kann auf einfache Art der als Energiesparmodus dienende zweite Betriebsmodus wieder verlassen werden, so dass dann im ersten Betriebsmodus wieder mithilfe der Antriebseinheit die Verstellposition der Komponente aktiv durch eine Bedieneingabe einer Bedienperson geändert werden kann.Furthermore, it is advantageous if, when the operating element is activated, a change of the operating mode takes place from the second operating mode to the first operating mode. As a result, the second operating mode serving as energy-saving mode can be left again in a simple manner, so that the adjustment position of the component can then be actively changed again by an operating input of an operator in the first operating mode with the aid of the drive unit.
Nach erneutem Ablauf des Zeitraums wechselt die Steuereinheit wieder vom ersten Betriebsmodus in den zweiten Betriebsmodus. Dieser Wechsel vom ersten in den zweiten Betriebsmodus und vom zweiten Betriebsmodus in den ersten Betriebsmodus kann beliebig oft wiederholt werden, jedoch vorzugsweise nur bis ein Wechsel vom zweiten in den ersten Betriebsmodus infolge der Detektion einer Änderung der Verstellposition der Komponente durch die zweite Sensoreinheit erfolgt ist.After renewed expiry of the period, the control unit changes back from the first operating mode in the second operating mode. This change from the first to the second operating mode and from the second operating mode to the first operating mode can be repeated as often as desired, but preferably only until a change from the second to the first operating mode has taken place as a result of the detection of a change in the adjustment position of the component by the second sensor unit.
Besonders vorteilhaft ist es, wenn der Operationstisch ein mobiler Operationstisch oder ein bewegbarer Operationstisch ist, bei denen die Stromversorgung der Antriebseinheit, der Steuereinheit, der ersten Sensoreinheit und der zweiten Sensoreinheit mithilfe eines Akkumulators erfolgt. Dadurch kann bei geeigneter Auslegung des Akkumulators erreicht werden, dass dieser auch bei längeren Operationen nicht nachgeladen oder gegen einen anderen Akkumulator ausgetauscht werden muss. Dadurch ist ein reibungsloser Operationsablauf gewährleistet.It is particularly advantageous if the operating table is a mobile operating table or a movable operating table, in which the power supply of the drive unit, the control unit, the first sensor unit and the second sensor unit by means of a battery. This can be achieved with a suitable design of the accumulator that this does not have to be recharged even during prolonged operations or replaced with another accumulator. This ensures a smooth operation process.
Ein zweiter Aspekt der Erfindung betrifft ein Verfahren zum Steuern eines Operationstischs, bei dem mithilfe einer elektrischen Antriebseinheit mindestens eine verstellbare Komponente des Operationstischs verstellt wird und bei dem mithilfe einer ersten Sensoreinheit eine Verstellposition und/oder eine Änderung der Verstellposition der Komponente detektiert wird. In einem ersten Betriebsmodus einer Steuereinheit wird die erste Sensoreinheit aktiviert. Ferner ist in dem ersten Betriebsmodus die Antriebseinheit zum Verstellen der Komponente mithilfe eines Bedienelements aktivierbar.A second aspect of the invention relates to a method for controlling an operating table in which at least one adjustable component of the operating table is adjusted by means of an electric drive unit and in which an adjustment position and / or a change in the adjustment position of the component is detected by means of a first sensor unit. In a first operating mode of a control unit, the first sensor unit is activated. Furthermore, in the first operating mode, the drive unit for adjusting the component can be activated by means of a control element.
In einem zweiten Betriebsmodus der Steuereinheit wird die erste Sensoreinheit deaktiviert. Ferner ist im zweiten Betriebsmodus die zweite Sensoreinheit zum Überwachen einer Verstellposition der Komponente aktiviert. Es wird vom ersten in den zweiten Betriebsmodus umgeschaltet, wenn die Antriebseinheit einen voreingestellten Zeitraum lang nicht aktiviert worden ist. Ferner wird vom zweiten in den ersten Betriebsmodus umgeschaltet, wenn durch die zweite Sensoreinheit eine Änderung der Verstellposition der Komponente detektiert wird. Dadurch ist ein energiesparender Betrieb eines Operationstischs möglich, wobei eine Gefährdung eines Patienten bei einer Operation vermieden wird.In a second operating mode of the control unit, the first sensor unit is deactivated. Furthermore, in the second operating mode, the second sensor unit is activated for monitoring an adjustment position of the component. It is switched from the first to the second operating mode when the drive unit has not been activated for a preset period. Furthermore, it is switched from the second into the first operating mode when a change in the adjustment position of the component is detected by the second sensor unit. Thereby, an energy-saving operation of an operating table is possible, whereby a risk to a patient during surgery is avoided.
Das Verfahren gemäß dem zweiten Aspekt der Erfindung kann mit den zuvor für den Operationstisch angegebenen vorteilhaften Weiterbildungen weitergebildet werden, wobei die angegebenen bzw. erforderlichen Verfahrensschritte von der Steuereinheit in Verbindung mit den Sensoreinheiten und der Antriebseinheit ausgeführt werden.The method according to the second aspect of the invention can be further developed with the advantageous developments given above for the operating table, wherein the specified or required method steps are carried out by the control unit in conjunction with the sensor units and the drive unit.

Der Operationstisch 30 umfasst weitere nicht dargestellte Antriebseinheiten zum Verändern der Lage der Patientenlagerfläche 31, insbesondere zur Längsneigungsverstellung und/oder zur Kippneigungsverstellung der Patientenlagerfläche 31 sowie zur Verstellung von einzelnen Komponenten der Patientenlagerfläche 31 gegenüber weiteren Komponenten, wie dies insbesondere in
Ferner ist die Lage des Rückenteils 44 gegenüber dem Mittelteil 42 durch eine Drehung um die Drehachse 58 und die Lage des Kopfteils 46 gegenüber dem Rückenteil 44 der Patientenlagerfläche 31 durch eine Drehung um die Drehachse 60 verändert worden. Auch die Lage der die Segmente 34 und 36 bzw. 32 und 38 umfassenden Beinplatten ist gegenüber dem Mittelteil 42 der Patientenlagerfläche 31 durch eine entsprechende Drehung der Segmente 32 bis 38 um die Drehachsen 62, 64 und 66 geändert worden. Die verringerte Höhe der Patientenlagerfläche ist durch den Pfeil P5 in
In einem ersten Betriebsmodus der Steuereinheit 52 erfasst eine nicht dargestellte erste Sensoreinheit die Höhe bzw. die Änderung der Höhe der Patientenlagerfläche 31 oder die Länge der Operationstischsäule 40 bzw. eine Änderung der Länge der Operationstischsäule 40 exakt, wobei insbesondere zur Auswertung der Sensorsignale dieser ersten Sensoreinheit durch die Steuereinheit 52 Steuerfunktionen mit relativ großem Energiebedarf aktiviert sind. Die Energieversorgung der Steuereinheit 52 und der ersten Sensoreinheit sowie der Antriebseinheiten 41 zur Verstellung der Komponenten erfolgt über einen in der Operationstischsäule 40 angeordneten Akkumulator 53. Erfolgt nun eine voreingestellte Zeit lang keine Aktivierung der Antriebseinheit 41 durch eine Betätigung der Bedienelemente 14 bis 28 der Fernbedienung 12, so wechselt die Steuereinheit 52 vom ersten Betriebsmodus in einen zweiten Betriebsmodus, der als Energiesparmodus dient und in dem die Antriebseinheit 41 und die erste Sensoreinheit deaktiviert sind. Die erste Sensoreinheit wird auch als Positionssensoreinheit bezeichnet.In a first operating mode of the
Im zweiten Betriebsmodus ist eine zweite Sensoreinheit zum Überwachen der Änderung der Verstellposition der Komponente 40 aktiviert. Der Aufbau und die Funktion dieser zweiten Sensoreinheit wird nachfolgend in Verbindung mit
Die Antriebseinheit 41 umfasst eine als Reedschalter 90 ausgeführte zweite Sensoreinheit 90, die abhängig von der Position von an der Umfangsfläche eines Flanschs des Zahnrads 72 in einem Winkelabstand von 90° angeordneten Magneten 82a bis 82d ihren Schaltzustand, d. h. ihren Signalszustand, ändert, der von einer Überwachungsschaltung 84 der Steuereinheit 52 ausgewertet wird. Bei einer Drehung der Abtriebswelle des Elektromotors 70 in Richtung des Pfeils P6 erfolgt eine Rotation der Gewindespindel 78 in Richtung des Pfeils P7, sodass der Magnet 82d gegenüberliegend der Sensoreinheit 90 angeordnet wird, wie dies in
In
Die Positionssensoreinheit 86 ist im ersten Betriebsmodus der Steuereinheit 52 aktiv. Im zweiten Betriebsmodus, der ein Energiesparmodus des Operationstischs 30 ist, ist sowohl der Elektromotor 70 als auch die Positionssensoreinheit 86 deaktiviert. Ferner ist nur die Steuerfunktion der Steuerschaltung 84 der Steuereinheit 52 aktiv, die eine Änderung des Schaltzustandes des Reedschalters 90 im zweiten Betriebsmodus detektiert. Weiterhin erfasst die Steuerschaltung 84 der Steuereinheit 52 Bedieneingaben über die Fernbedienung 12, wobei die Steuerschaltung 84 eine Änderung des Betriebsmodus der Steuereinheit 52 vom zweiten Betriebsmodus in den ersten Betriebsmodus bewirkt, wenn im zweiten Betriebsmodus eine Änderung des Schaltzustands des Reedschalters 90 oder eine Bedieneingabe über die Fernbedienung 12 erfolgt. Erfolgt der Betriebsmoduswechsel vom zweiten Betriebsmodus in den ersten Betriebsmodus aufgrund der Änderung des Schaltzustands des Reedschalters 90, wird nachfolgend die Positionssensoreinheit 86 ununterbrochen aktiviert, sodass eine aktive Höhenkontrolle der Patientenlagerfläche 31 erfolgt. Insbesondere wird bei einer mithilfe der Positionssensoreinheit 86 detektierten Positionsabweichung von einer voreingestellten Position eine Positionskorrektur durch eine geeignete Ansteuerung des Elektromotors 70 durchgeführt.The
Der Elektromotor 70 umfasst eine Bremseinheit, die im stromlosen Zustand eine Bremskraft auf die Abtriebswelle 71 des Elektromotors 70 ausübt und somit auf die Abtriebswelle 71 des Elektromotors 70. Dadurch wird eine Positionsänderung des Koppelelements 80 bei deaktiviertem Elektromotor 70 verhindert. Bei einem Defekt dieser Bremseinheit kann sich die Position des Koppelelements 80 jedoch insbesondere aufgrund der Gewichtskraft der Patientenlagerfläche 31 und des auf dieser liegenden Patienten ändern. Eine solche aufgrund eines Fehlers der Bremse bewirkten Positionsänderung wird dann mithilfe des Reedschalters 90 in Verbindung mit den Magneten 82a bis 82d detektiert. Indem nachfolgend verhindert wird, dass auch nach dem Ablauf einer voreingestellten Wartezeit von dem ersten Betriebsmodus in den zweiten Betriebsmodus gewechselt wird, ist sichergestellt, dass sich die Position des Koppelelements 80 durch die dann aktivierte Positionsüberwachung und Korrektur durch die Positionssensoreinheit 86 in Verbindung mit dem Elektromotor 70 sichergestellt ist.The
In
Bei einer Detektion der Änderung des Schaltzustands des Reedschalters 90 mit Hilfe der Steuerschaltung 84 bewirkt diese eine Änderung des Betriebsmodus der Steuereinheit 52 vom zweiten Betriebsmodus in den ersten Betriebsmodus, in dem die Steuerfunktionen 92 bis 96 wieder aktiviert sind. Ferner umfasst die Steuerschaltung 84 die Auswertung der Signale einer Sende- und/oder Empfangseinheit 98 zum Empfangen von über die Fernbedienung 12 gesendeten Bedieninformationen. Beim Empfangen solcher Bedieninformationen wird ebenfalls durch die Steuerfunktion 84 der Betriebsmodus der Steuereinheit 52 von dem zweiten Betriebsmodus in den ersten Betriebsmodus geändert.Upon detection of the change in the switching state of the
Grundsätzlich erfolgt die Änderung des Betriebsmodus von dem ersten Betriebsmodus in den zweiten Betriebsmodus, wenn während eines voreingestellten Zeitraums keine Bedieninformationen von der Fernbedienung 12 zur Sende-/Empfangseinheit 98 gesendet worden sind. Jedoch erfolgt dann kein Wechsel von dem ersten Betriebsmodus in den zweiten Betriebsmodus, wenn aufgrund einer Schaltzustandsänderung des Reedschalters 90 im zweiten Betriebsmodus eine Umschaltung vom zweiten Betriebsmodus in den ersten Betriebsmodus erfolgt ist. Grundsätzlich wird davon ausgegangen, dass die Antriebseinheit 41 einen Fehler aufweist, wenn im zweiten Betriebsmodus eine Änderung des Schaltzustands des Reedschalters 90 detektiert wird. Davon ausgehend wird dann der erste Betriebsmodus beibehalten, um den sicheren Betrieb des Operationstischs 30 sowie die damit verbundene sichere Durchführung einer Operation zu gewährleisten.In principle, the change of the operating mode from the first operating mode to the second operating mode takes place when no operating information has been sent from the
Reedschalter 90, die auch als Reedkontakte bezeichnet werden, können als in einem Glasrohr eingeschmolzene Kontaktzungen ausgeführt sein. Diese Kontaktzungen können insbesondere eine Eisen-Nickellegierung aufweisen, so dass die Kontaktzungen magnetisch betätigbar sind. Durch die Anordnung der Kontaktzungen in einem Glasrohr sind Reedschalter hermetisch dichte Schalter, die durch ein Magnetfeld betätigt werden. Die Kontaktzungen müssen zumindest in einem Teilbereich ferromagnetisches Material haben. Solche Reedschalter 90 haben eine geringe Baugröße verglichen mit konventionellen Kontakten und ermöglichen es, schnelle Schaltvorgänge auszuführen. Reedschalter 90 können als Öffner, Schließer oder Wechsler bzw. Umschalter ausgeführt sein.Reed switches 90, which are also referred to as reed contacts, can be embodied as contact tongues melted into a glass tube. These contact tongues may in particular have an iron-nickel alloy, so that the contact tongues are magnetically actuated. By arranging the contact tongues in a glass tube, reed switches are hermetically sealed switches that are actuated by a magnetic field. The contact tongues must have at least in a partial area ferromagnetic material.
Ferner kann die Erfindung im Bezug auf eine Ausführungsform wie folgt beschrieben werden. Ein Magnet bzw. mehrere Magnete 82a bis 82d werden an einem um eine Achse drehbares Bauteil, wie z.B. ein Kettenrad 72, ein Zahnrad oder eine Welle, innerhalb eines Antriebsstrangs der Antriebseinheit 41 des Operationstischs 30 befestigt. Bei einer Bewegung des drehbaren Bauteils 72 wird der Magnet bzw. werden die Magnete 82a bis 82d an einem Reedschalter 90 vorbeigeführt. Die Änderung des Schaltzustands des Reedschalters 90 und die damit bewirkte Änderung eines Signalzustands des Reedschalters 90 bei einer entsprechenden Spannungsversorgung des Reedschalters 90 kann als Signal zum Wechsel des Betriebsmodus vom zweiten Betriebsmodus in den ersten Betriebsmodus verwendet werden. Wird die Position des Antriebmotors 70 über ein Inkrementalgeber im ersten Betriebsmodus erfasst, kann durch die Anordnung des Reedschalters 90 sichergestellt werden, dass eine Drehung des drehbaren Bauteils 72 detektiert wird. Die erwähnten Inkrementalgeber geben keine Absolutposition an, sondern erfassen lediglich relative Positionsänderungen, die nur bei einer aktivierten entsprechenden Steuerfunktion 92 der Steuereinheit 52 ausgewertet werden können. Wird die Steuerfunktion 92 im zweiten Betriebsmodus, d.h. zeitweise, deaktiviert, um z.B. Energie zu sparen, und findet in diesem Zeitraum eine Bewegung des Antriebs 41 statt, so wird diese Bewegung durch den Inkrementalgeber nicht erfasst bzw. wird von der Steuereinheit 52 nicht ausgewertet. Erfolgt eine Änderung des Betriebsmodus vom zweiten Betriebsmodus in den ersten Betriebsmodus aufgrund eines Schaltvorgangs des Reedschalters 90, wird die Steuereinheit 52 kontinuierlich im ersten Betriebsmodus betrieben, so dass eine weitere Fehlfunktion vermieden wird.Furthermore, the invention with respect to one embodiment may be described as follows. One or
Die in Verbindung mit den Figuren beschriebene Möglichkeit der Umschaltung der Steuereinheit vom ersten Betriebsmodus in den zweiten Betriebsmodus zum Energiesparen und das Überwachen der Position bzw. der Änderung der Position der Komponente im zweiten Betriebsmodus mit Hilfe der zweiten Sensoreinheit ist zwar in Verbindung mit der Antriebseinheit 41 zum Antrieb der Höhenverstellung der Operationstischsäule 40 beschrieben worden, jedoch kann dieselbe Vorgehensweise bei jeder anderen Antriebseinheit des Operationstischs 30 vorgesehen werden, insbesondere Antriebseinheiten zum Verändern der Position der Komponenten 32 bis 38, 42 bis 48.The possibility of switching the control unit from the first operating mode to the second operating mode for saving energy and monitoring the position or the change of the position of the component in the second operating mode with the aid of the second sensor unit is in connection with the
