Description

Method and device for operating a mobile operating table

The invention relates to a method and apparatus for operating a mobile operating table having a patient support surface, an operating table column and an operating table base. The operating table further has rollers and a traction drive unit for operating the operating table. The traction drive unit is activated by operating a control element associated with the traction drive unit.

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. Usually, stationary operating tables do not have an operating table base. Movable operating tables have an operating table column base 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 dolly is also referred to as a mobile operating table system.

The operating table column feet of mobile operating tables have rollers for operating the operating table. Mobile operating tables are thus movable without further aids. In the mobile operating tables, the rollers are lockable, so that the operating table is not displaced during surgery, and / or the pedestal is lowered relative to the rollers, so that the operating table is safely on the floor during surgery. The mobile operating tables also electric traction drives with soft start and safety braking function are known to move the mobile operating table using the electric traction drive. The operation of this drive unit via at least one control element, in particular via a corded or wireless remote control. In traction drive units with at least two speed levels can then be done switching the speed level. This is particularly useful when a mobile operating table has been moved from the operating room and continue to be driven along a corridor of an operating tract over a longer distance, for example. In the operating room itself, maneuvering is problematic due to the usually quite tight space conditions and a large number of obstacles, so that for this purpose a low drive speed of the travel drive is advantageous. In long corridors, as they are also common in the surgical wing of hospitals, however, a higher speed is desirable to ensure a speedy workflow. In known switching operations, the movement of the operating table must be stopped for a short time to change the speed and a complex setting of the desired higher speed level via a menu of the HMI device or the remote control can be performed. In order to subsequently set the lower speed level again, the procedure for setting the speed level in the menu of the operator panel had to be repeated. As a result, the conversion of the speed is relatively complicated in known mobile operating tables. An alternative possibility for changing the speed could be that a separate control element on the operating device, in particular a remote control, is provided for the speed levels. However, this makes the operating device rather confusing. In particular, when the operating device also serves to operate adjustable components of an operating table during an operation, it is off Clarity reasons not useful to provide a variety of controls for functions that are not needed in the operation itself.

From the document DE 19955116 AI a control unit for controlling the drives of a removable from an operating table column operating table storage surface with electromotive adjustable components, consisting of a power supply, a controller and a control unit known. The HMI device is integrated into a transport cart for transporting the operating table storage area.

Starting from the known prior art, it is an object of the invention to provide a method and an apparatus for operating a mobile operating table, through which a simple activation of a traction drive unit for moving the operating table with different drive speeds is possible.

This object is achieved by a method having the features of claim 1 and by a device having the features of the independent device claim. Advantageous developments of the invention are specified in the dependent claims.

By a method for operating a mobile operating table with the features of claim 1 it is achieved that the first drive speed is activated by a single operation of the operating element and that the second drive speed is activated by a double actuation of the operating element.

As a double operation is a double-click, ie a two-time activation of the actuator within a preset period of time between a first actuation of the control element and a second actuation of the control element, or an inverse double-click, ie the one-time deactivation of Bedienele- for a maximum preset interruption time and / or the deactivation of the control element twice for a maximum preset interruption time within a preset period of time between the first deactivation of the operating element and the second deactivation of the operating element.

By a double actuation of the operating element, a simple switching over of the drive speed from the first drive speed to the second drive speed during the drive drive unit activated with the first drive speed is possible without the drive drive unit having to be temporarily deactivated for this purpose. Also, the switching of the drive speed with only one control is possible. This makes it possible to operate the control element in an intuitive manner, at least after familiarization, in order to activate the first drive speed and to activate the second drive speed of the drive unit. The first drive speed is preferably smaller than the second drive speed. Thereby, the first drive speed for slow operation of the operating table, in particular for exact positioning and / or maneuvering of the operating table can be used, and the second drive speed for covering longer distances with higher speed.

It is advantageous if the drive speed of the travel drive unit is changed by the double operation of the first drive speed to the second drive speed. As a result, a very comfortable changeover of the drive speed is possible, which impairs the workflow in the operating room and in the operating tract of a hospital as little as possible. Further, in the case where a double operation is made by interrupting the operation of the first operating member, it is necessary for the double operation if the interruption is smaller than a preset interruption period. The interruption period is preferably preset to a value in the range between 100 ms and 800 ms, in particular to a value in the range between 200 ms and 500 ms. In particular, an interruption period may be preset to a value of 300 ms. As a result, a simple and comfortable operation of the control element for activating the second drive speed is possible.

It is advantageous if a double operation is only accepted if the interruption lasts longer than 30% of the preset interruption period or if the interruptions each last longer than 30% of the preset interruption period. For a preset interruption period of, for example, 300 ms, the minimum interruption period for the double actuation is thus 90 ms. As a result, incorrect operation, in particular by bouncing a switching element of the actuating element, effectively avoided.

Furthermore, it is advantageous if the travel drive unit is deactivated when the first operating element has not been actuated for a preset interruption period. This ensures that the traction drive unit does not remain activated when the actuating element is no longer actuated, which avoids danger to persons and damage to the operating table.

Further, it is advantageous if in a double actuation of the first operating element with activated second drive speed of the traction drive unit, the first drive speed of the traction drive unit is activated again. This is a simple switching from the second drive speed to the first drive speed possible without the drive unit must be stopped for this purpose.

Alternatively, in a double actuation of the first control element with activated second drive speed, a third drive speed can be activated. The third drive speed is in particular greater than the second drive speed, so that in this way an even faster drive speed can be selected.

It is particularly advantageous if a second control identifier is provided, upon the actuation of which a release of the traction drive unit for driving the operating table takes place. In a single operation of the first operating element, the traction drive unit is activated at the first drive speed. In a double operation of the first operating element, the traction drive unit is activated at the second drive speed. In this case, the traction drive unit can only be activated when the second operating element is actuated, wherein the traction drive unit is deactivated when the second operating element is not actuated. As a result, the first control element only has to be actuated by a single operation for activating the first drive speed and by double-clicking to activate the second drive speed, whereby a non-inverse double-click, i.e. a double-click, is activated for actuation. a "normal" double-click, can be used, whereby an even more intuitive operation is possible than an inverse double-click.

Furthermore, it is advantageous if, in further double actuations of the first operating element, the traction drive unit is activated with a higher drive speed as long as possible until the maximum drive speed of the traction drive unit has been reached. Alternatively, with a repeated double operation of the first operating element, the travel drive unit can be activated again with the first drive speed when the second drive speed is activated.

As a result, a simple switching and choice of different speed levels is easily possible.

It is particularly advantageous if, during or after deactivation of the traction drive unit, a brake unit is additionally activated. As a result, the movement of the operating table can be actively stopped so that hazards to persons and damage to the operating table are effectively avoided. By means of the brake unit can be prevented in a simple way alternatively or additionally effectively moving the mobile operating table with non-activated drive unit.

A second aspect of the invention relates to an apparatus for operating a mobile operating table having a patient support surface, an operating table column, and an operating table base, the operation table column foot having rollers and a travel drive unit for operating the operating table. The device further has a first operating element, by the actuation of which a control unit of the device activates the travel drive unit. The control unit activates the traction drive unit at a first drive speed by a single operation of the operating element. Furthermore, the control unit activates the travel drive unit by a double actuation of the operating element at a second drive speed. In this way, a simple activation and / or change of the drive speed of the movement of the operating table can take place.

The device according to the invention can be developed with the features of the dependent claims, wherein the specified method steps then be executed by the control unit in conjunction with the controls and the drive unit.

In the invention, the first and / or second operating element can be provided via a remote control, in particular a wired or wireless remote control of the operating table, or via operating elements arranged directly on the operating table.

Furthermore, it is advantageous if the speed changes from standstill to the first drive speed, from the first drive speed to the second drive speed, from the second drive speed to a higher third drive speed, from the third drive speed to the second drive speed, from the second drive speed to the first drive speed and / or from the first drive speed to a stop via so-called acceleration ramps, ie with a uniform positive or negative acceleration, done. As a result, sudden acceleration is avoided and there is a so-called soft start.

Further features and advantages of the invention will become apparent from the following description, which illustrates the invention with reference to embodiments in conjunction with the accompanying figures.

Show it:

Figure 1 is a mobile operating table with several using a wireless

Remote control of electromotive adjustable components as well as an activatable via the wireless remote control in two speed stages drive unit for moving the operating table, wherein the operating table is shown in a first lowered position;

FIG. 2 shows the operating table according to FIG. 1 in a second raised position for moving the operating table;

3 shows a status diagram of a polling cycle of the actuating element for

Activating the travel drive unit of the operating table at the first drive speed and for switching the speed stage of the travel drive unit from the first drive speed to the second drive speed; and

Figure 4 shows another embodiment of a remote control for operating an operating table.

FIG. 1 shows an arrangement 10 with a remote control 12, which has a plurality of operating elements 14 to 28, with the aid of which displaceable components 32 to 46 of a mobile operating table 30 are adjusted, ie changed in their position in space and / or with respect to other components 32 to 46, can be. The individual components 32 to 46 or groups of these components 32 to 46 are assigned to the operating elements 14 to 24 of the remote control 12 so that upon actuation of a control element 14 to 24, a corresponding adjustment action of the component 32 to 46 or component group assigned to this operating element 14 to 24 is carried out becomes. The mobile operating table 30 has an operating table column foot 41, a patient support surface 31 that includes the components 32 to 36, 42 to 46, and an operating table column 40 disposed between the surgical table column foot 41 and the patient support surface 31. Inside the operating table column 40, there is disposed a travel drive unit 48 a control unit for controlling the driving drive of the mobile operating table 30, an electric motor for driving the mobile operating table 30 and an accumulator for powering the control unit and the electric motor comprises. In the lowered state of the mobile operating table 30 shown in FIG. 1, the rollers 50 to 56 provided for operating the operating table 30 are arranged inside the operating table base 41 and do not project downwards over support elements on which the operating table base foot rests in the lowered state not shown supports the floor.

FIG. 2 shows the arrangement 10 according to FIG. 1, wherein the rollers 50 to 56 of the mobile operating table 30 have been extended downward so that the mobile operating table 30 can be displaced by means of these rollers 50 to 56. The rollers 50 to 56 can thereby be brought from their retracted position shown in FIG. 1 into their extended position shown in FIG. 2 by means of an electric motor and / or an electrically driven or manually operated hydraulic unit. To extend the rollers 50 to 56, the control element 26 is activated once. Upon actuation of the operating element 26 again, the operating table 30 is lowered again from the raised position shown in FIG. 2 into the lowered position shown in FIG. When the control element 28 is activated once, the electric motor of the travel drive unit 48 is activated at a first drive speed, so that the mobile operating table 30 is driven at this first drive speed in the direction of the arrow PI. In this case, the drive can take place via one or more rollers 50 to 56 or via another drive wheel, not shown, or via a drive roller, not shown.

The traction drive unit 48 or the electric motor remains activated at the first drive speed as long as the operating element 28 is actuated. If the operation of the control element 28 is longer than a pre-set interruption interrupted period, the traction drive unit 48 is deactivated, ie the drive of the operating table 30 by means of the electric motor is stopped and a brake is activated. If, however, the operation of the actuator 28 is interrupted for a time less than the interruption period and then again interrupted for the period smaller than the interruption period, ie when a double actuation of the control element 28 takes place, a second drive speed of the traction drive unit 48 is activated. Preferably, the electric motor is driven such that it has a correspondingly higher output speed than when activating the first drive speed.

FIG. 3 shows a state diagram of states for activating and deactivating the operating element 28. After the system has been initialized in step S10, the operating element 28 is in the state S12- "released", so that the traction drive unit is deactivated, and if it is detected that the operating element 28 has been pressed, a state change is made to state S14- " , whereby the travel drive unit 48 is activated at a first drive speed. It is then determined that the control 28 is no longer activated, i. that it has been released, a state change takes place from state S14 to state S16- "1. Let go. "

If it is determined that the control element 28 is not actuated for more than 300 ms, a state change takes place from the state S16 to the state S12- "released", in which the travel drive unit 48 is deactivated.

However, if the operating element 28 is repeatedly activated within 300 ms, a state change takes place from state S16 to state S18- "1. If the operating element 28 is not deactivated again within 300 ms, a state change takes place after 300 ms from the state S18 to the state S14- "pressed". If, however, a repeated release of the control identifier 28 takes place within this 300 ms, a state change takes place from the state S18 to the state S20- "2. Once the operating element 28 is not reactivated within 300 ms, a state change takes place from the state S20 to the state S12- "released", in which the travel drive unit 48 is deactivated. However, if, starting from the state S20, a renewed actuation of the operating element 28 within 300 ms, a state change takes place from the state S20 to the state S22- "2. Click ", whereby the second drive speed of the traction drive unit 48 is activated. If the operating element 28 is subsequently not actuated, a state change takes place from the state S22 to the state S12-" released ", so that the traction drive unit 48 is deactivated.

FIG. 4 shows a remote control 62 which can be used as an alternative to the remote control 12. The remote control 62 has a display 64 for displaying information. Furthermore, the remote control 62 has a plurality of controls 66 to 112, via the various operating inputs for changing the position of the components 32 to 46 of the mobile operating table 30 are conveniently entered. In addition, the remote control 62 has a control element 26 for extending the transport rollers 50 to 56 and a control element 28 for activating the traction drive unit 48 either in single operation with the first drive speed and double operation with the second drive speed.
