Description

The present disclosure relates to a surgical table control device, a surgical table comprising a surgical table control device, and a surgical table positioning system comprising a surgical table control device. More specifically, the present disclosure relates to a surgical table control device configured to control a movable section of a surgical table.
Surgical tables typically comprise movable sections that enable a patient supported on the table to be positioned in an optimal position for the surgical procedure that is being performed. Generally, the patient support surface of a surgical table comprises several movable sections, including a head section, a body section, a seat section, and a leg section. The height of the table is also typically adjustable. The movable sections of a surgical table are often movable by actuators that are controlled by control circuitry. A surgical table control device is typically coupled to the table control circuitry, and is configured to enable a user to control the actuators to adjust the position of the movable sections of the table.
Often in surgical procedures, the surgeon is not in control of the surgical table control device, and so is also not in direct control of the position of the surgical table. This can be for a variety of reasons, such as the surgeon is performing a complex procedure on the patient, or the surgeon is operating a robotic operating system from a console that is remote from the surgical table. When a surgeon is not in control of the surgical table control device, the surgeon is required to instruct another person to control the surgical table control device to position the surgical table in a desired position. However, there is a risk that the person controlling the position of the surgical table may misunderstand the instructions from the surgeon, or may not correctly hear the instructions from the surgeon.
It would be desirable to be able to reliably position a surgical table accurately in a desired position of a person who is not directly in control of the table.
According to the present disclosure, there is provided a surgical table control device comprising a user interface and device control circuitry. The user interface comprises an input to enable a user to control movement of a corresponding movable section of a surgical table. The device control circuitry is configured to receive a suggested position of the corresponding movable section of the surgical table. The device control circuitry is further configured to determine when the corresponding movable section of the surgical table is in the suggested position, and notify a user when the corresponding movable section of the surgical table is in the suggested position. The device control circuitry is further configured to, in response to an interaction of a user with the input of the user interface, send a signal to move the corresponding movable section of the surgical table according to the interaction of the user with the input.
By configuring a surgical table control device to receive a suggested position of a movable section of the surgical table, and notify a user when the movable section is in the suggested position, the surgical table control device of this disclosure advantageously enables a person remote from the surgical table to suggest a position for the movable section of the surgical table, and a person at the surgical table in control of the surgical table control device to reliably position the movable section of the surgical table accurately in the suggested position. As an example, such a surgical table control device may be particularly useful in robotic surgery scenarios, wherein a surgeon is remote from the surgical table at the robotic control console, and needs to instruct a person located at the surgical table, such as an anaesthetist, to position a movable section of the surgical table in a particular manner for a procedure.

In this embodiment, the remote device 30 is a tablet computer. The remote device 30 comprises a user interface 31 comprising a touchscreen display 32 with a plurality of inputs 33a-b. Each input 33a-b of the user interface 31 is configured to enable a user to input a suggested position for each of the movable sections 14a-e of the surgical table 10. Since the user interface 31 comprises touchscreen display 32, the user interface comprises a graphical user interface (GUI), and the inputs 33a-b comprise regions of the touchscreen display 32 that are selectable by a touch of a finger of a user. In Figures 1, 2, and 3, the user interface 31 is only shown having two inputs 33a-b; however, it will be appreciated that the inputs 33a-b comprise graphical icons displayed on the display 32, and the number of graphical icons displayed on the display 32 can vary depending on the situation, and on the previous interactions of a user with the GUI. In Figures 1, 2, and 3, a suggested position has already been selected by a user of the remote device 30, and the two inputs 33a-b displayed on the GUI are inputs to enable the user to send, 33a, or reject sending, 33b, the suggested position to the surgical table control device 20.
The remote device 30 further comprises remote control circuitry 34. The remote control circuitry 34 is coupled to the user interface 31, such that an interaction of a user with an input 32a-b of the user interface 31 is detected by the remote control circuitry 34.
The remote device 30 is coupled to the surgical table control device 20 via a wireless connection 26. The wireless connection 26 enables signals and data to be sent from the remote device 30 to the surgical table control device 20, and enables signals and data to be sent from the surgical table control device 20 to the remote device 30. The device control circuitry 24 comprises a receiver (not shown) for receiving signals and data from the remote control circuitry 34, and a transmitter (not shown), for sending signals and data to the remote control circuitry 34. Similarly, the remote control circuitry 34 comprises a receiver (not shown) for receiving signals and data from the device control circuitry 24, and a transmitter (not shown), for sending signals and data to the device control circuitry 24.
The remote control circuitry 34 is configured to, in response to a user pressing the send input 33a of the user interface 31, send a signal to the device control circuitry 24 providing an indication of the suggested position of the movable sections 14a-e of the surgical table 10 to the surgical table control device 20. The device control circuitry 24 is further configured to, in response to receiving the signal from the remote control circuitry 34, determine whether the movable sections 14a-e of the surgical table are in the suggested position. The device control circuitry 24 is configured to determine whether the movable sections 14a-e of the surgical table 10 are in the suggested position by comparing the current position the surgical table 10 received from the surgical table 10 to the suggested position of the surgical table 10 received from the remote device 30.
The device control circuitry 24 is configured to, in response to receiving the signal from the remote control circuitry 34 and determining that the current position of the surgical table 10 is not the suggested position of the surgical table 10, display an indication of how to move the movable sections 14a-e of the surgical table 10 to reach the suggested position on the display 23. In this embodiment, the indication of how to move the movable sections 14a-e of the surgical table 10 to reach the suggested position is in the form of arrows indicating the direction of movement required for a movable section 14a-e, as illustrated in Figure 2. In addition, the input buttons 22a-h of the user interface 21 comprise lights, and the device control circuitry 24 is configured to illuminate the lights of the input buttons 22a-h that need to be pressed to move the movable sections 14a-e of the surgical table 10 to reach the suggested position, also as illustrated in Figure 2.
The device control circuitry 24 is further configured to in response to a continuous interaction of a user with an input 22a-h of the user interface 21, send signals to the surgical table 10 to continuously move the corresponding movable sections 14a-e of the surgical table 10 until the interaction of the user with the input 22a-h of the user interface stops. In other words, corresponding movable sections 14a-e of the surgical table 10 move continuously while an input 22a-h of the surgical table control device 20 is being pressed by a user, and stop moving when the input 22a-h is released by the user. The device control circuitry 24 is further configured to stop sending signals to the surgical table 10 to continuously move the corresponding movable sections 14a-h of the surgical table 10 in response to a continuous interaction of a user with an input 22a-h of the user interface 21 when it is determined by the device control circuitry 24 that the corresponding movable sections 14a-h of the surgical table 10 are in the suggested position, regardless of whether the continuous user interaction with the input 22a-h stops. This helps to reliably position the surgical table 10 in the suggested position, even if the user of the surgical table control device does not realise that the movable sections 14a-e of the surgical table 10 have reached the suggested position. The device control circuitry 24 is further configured to resume sending signals to the surgical table 10 to move the corresponding movable sections 14a-e of the surgical table 10 after the continuous user interaction with the input 22a-h has stopped and when a new user interaction with one of the user inputs 22a-h is initiated.
The surgical table control device 20 further comprises a notifier 25 for notifying a user when the surgical table 10 is in the suggested position. In this embodiment, the notifier 25 comprises a loudspeaker. The device control circuitry 24 is coupled to the notifier 25, and the device control circuitry 24 is configured to send a signal to the notifier 25 when it is determined that the surgical table 10 is in the suggested position. In other words, the surgical table control device 20 is configured to emit a sound when it is determined that the surgical table 10 is in the suggested position to notify a user that the surgical table 10 is in the suggested position, as shown in Figure 3. Such a notification helps alert a user of the surgical table control device that the surgical table is in the suggested position.
Accordingly, in the surgical table positioning system 1 is configured such that, when the movable sections 14a-e are moved into the suggested position, the movement of the movable sections 14a-e stops, and the surgical table control device 20 plays a sound to indicate that the suggested position has been reached.

The current position of the movable sections 14a-e corresponding to the selected displayed text option 27c is also displayed on the display 23 in the form of a progress bar 29, with the current position of the movable sections 14a-e corresponding to the selected displayed text option 27c being indicated by a point 29a on the progress bar 29.
The device control circuitry is further configured to display an indication of how to move the movable sections 14a-e of the surgical table 10 into the suggested position. In Figure 4, the height position 27c is selected by a user on the touchscreen display 23. A graphical indication 28 of how to move the movable sections 14a-e of the surgical table 10 corresponding to the selected displayed text option 27c is displayed on the display, next to the text, in the form of an arrow pointing in the direction required to move the movable sections 14a-e. In addition, the suggested position for the movable sections 14a-e corresponding to the selected displayed text option 27c is shown as a point 29b on the progress bar 29. In Figure 4, the "zero" position 29c, or CPR position, for the movable sections 14a-e corresponding to the selected displayed text option 27c is also displayed on the progress bar 29.
