  Further, the operating table S of the present embodiment has various functions processed by the control unit. Below, various functions are explained in full detail.

"Position memory navigation processing function"
This position memory navigation processing function is a function for navigating the operation of the operating table S for bringing the patient into a predetermined position (specific posture), for example.

  The postural memory navigation processing function includes a memory function for storing position information for placing the patient in a predetermined posture in advance, and a navigation function for reading out the memory function and navigating the operation of the operating table S.

  The memory function stores position information in advance in association with predetermined number information (memory number), and the position information is actually stored in the operating table S (table 15 or column 5) by the operation of the operation button by the user. ) And the position information of each part of the back part, the waist part, the leg part, and the link part of the table 15 can be stored. Note that coordinate information indicating the positions of the plurality of operating tables S may be registered in advance as position information.

  The number information is a number assigned in order such as 1 to N, but this number may be expressed by a specific operation name or the like.

  Specifically, the registration of the position information is performed by operating the operation buttons 52A to 52G associated with the respective parts of the table 5, changing the operating table S to a predetermined position, and pressing the enter key 52K. Is called. Further, when the memory key 52L is pressed, the position information is associated with the number information and stored. Further, position information is read out by inputting this number information (memory number), and a navigation function described later can be operated.

  On the other hand, the navigation function reads out the position information stored in advance by the memory function, and navigates an operation necessary to change the operating table S to the position information, and is based on the position information stored in advance. When the operation buttons 52A to 52G necessary for the operation are turned on, and the positions of the respective parts specified by the operation buttons 52A to 52G match the position information stored in advance by the operation by the user, the operation buttons 52A to 52G are sequentially operated. It will be turned off.

  That is, the user operates in order until each of the lit operation buttons 52A to 52G is extinguished, and turns off all the lit operation buttons 52A to 52G to quickly and easily perform the operation to a predetermined position. It is possible to change the table.

  In the present embodiment, the position information is calculated from the values obtained from the encoders provided on the shafts 8, 31, 67, 68 and the like connecting the respective parts. However, the position information is an example and is limited to this form. It is not something.

  Next, a specific operation example of the posture memory navigation processing function will be described in detail with reference to FIG.

  First, the user inputs a memory number (number information) associated with predetermined position information and operates the posture memory navigation processing function (step S101).

  When the memory number is input by the user, the control unit reads position information associated with the memory number, and selects an operation button necessary for the operation based on the position information to light it (step S102). . Note that the operation buttons unnecessary for the operation are turned off. Thereby, the user can grasp at a glance the operation necessary to deform the operating table to a desired position.

  For example, in the case of the posture shown in FIGS. 12B and 12C from the initial state of FIG. 12A, the back is raised, the legs are lowered, the height of the table is raised, and the waist is turned over to the left. Since the operation to vertically rotate the waist is required, the operation button 55a for raising the back plate, the operation button 55b for lowering the leg, the operation button 55c for raising the height of the table, and the operation for turning the waist to the left. The button 55d and the operation button 55e for vertically rotating the waist are turned on.

  Next, the control unit determines whether or not each of the selected operation buttons 52a to 52e has been operated. If the operation button 52a to 52e has been operated, the respective units 15b and 15c of the table 15 corresponding to the operation buttons 55a to 55e. , 15d determines whether the position information matches the position information of the position information (step S103). If this determination is affirmed, the lit operation button is turned off (step S104). On the other hand, when negative, it waits until the position information of each part 15b, 15c, 15d corresponds.

  In this way, the user operates the operation buttons 55a to 55e that are lit and operates until all the operation buttons 55a to 55e are extinguished, so that the operating table S can be easily and quickly changed to a specific posture. It is possible to make it.

  Next, the control unit determines whether or not all the operation buttons 55a to 55e that are lit are turned off (step S105). If this determination is affirmed, the process ends. If the determination is negative, the process proceeds to step S103. Return to processing.

"Self-damage prevention function"
This self-breakage preventing function is a function for avoiding contact between the constituent members constituting the operating table during the operation of the operating table S, for example. Specifically, for example, when the operating table S is in the posture shown in FIGS. 12B and 12C, if the table 15 is vertically rotated without raising the column 5, the leg plate is lowered, There is a high possibility that the leg plate will come into contact with the column and break. That is, the present invention relates to processing when the operation button 55e is operated without operating the operation button 55c and then the operation button 55b is operated. In this case, if the operation button 55 b is continuously operated, it is assumed that the leg frame 15 d contacts the link mechanism 6 of the column 5.

  The accident breakage prevention function stores in advance the external information (coordinate information) on each component of the operating table in the storage unit, and the control unit stops the operating component based on the external shape information. In the case of approaching within the range defined in advance to other constituent members, the operation buttons corresponding to the constituent members that are operating are extinguished and notified to the outside (user).

  Next, a specific operation example of the self-breakage prevention function will be described in detail with reference to FIG. Note that the self-damage prevention function of the present embodiment is used in combination with, for example, the postural memory navigation processing function described above.

  When the number information associated with the predetermined position information is input by the user and the posture memory navigation processing function operates, the control unit reads the position information associated with the number, and is necessary for the operation based on the position information. The operation buttons 55a to 55e are turned on (step S201). Note that the operation buttons 52 unnecessary for the operation are turned off. Thereby, the user can grasp at a glance the operation necessary to deform the operating table to a desired position.

  Next, the control unit determines whether or not the structural member of the operating table S that is moved by the operation of the operation buttons 55a to 55e comes into contact with another structural member (step S202). Then, the operation button (for example, 55b) being operated is turned off (step S203). On the other hand, when the result is negative, the position information of each constituent member including the moving constituent member is continuously calculated. The determination as to whether or not the contact is made, for example, is made by calculating whether or not the distance between the constituent members is within 50 mm. In the present embodiment, the distance between the constituent members is within 50 mm. This value is changed as appropriate. Further, the determination of whether or not to touch is repeatedly performed while the constituent members of the operating table are moving by the operation of the operation buttons 55a to 55e.

  In this way, when the lit operation button (for example, 55b) is turned off, the user stops the operation button (for example, 55e) that is being operated, and the other operation button that is lit (for example, 55b). , 55c), it is possible to easily and quickly change the operating table to a specific posture while easily avoiding contact between the constituent members.

  Next, the control unit determines whether or not the distance between the component corresponding to the operation button 55b turned off and the other component exceeds 50 mm (step S204), and if the determination is affirmed, the operation turned off. The button 55b is turned on again (step S205), the process returns to step S202, and each process is continued. On the other hand, if the determination in step S204 is negative, the position information (distance) between the constituent member corresponding to the extinguished operation button 55b and the other constituent members is continuously calculated and waits until this determination is affirmed.

  In this way, the user can be notified that the operation button 55b can be operated again, the user operates the operation buttons 55a to 55e that are lit, and all the operation buttons 55a to 55e are turned off. It is possible to easily and quickly change the operating table to a specific position.

  In the present embodiment, the external notification is performed by turning off the operation buttons 55a to 55e. In addition to turning off the operation buttons, for example, a sound is output or the operation buttons 55a to 55e are output. The operation may be electrically disconnected (no operation signal is transmitted or the circuit is temporarily interrupted). You may perform these functions individually or in combination.

  In this embodiment, the determination as to whether or not the contact is made has an allowance for the distance, but, for example, the outline information (coordinate information) may be given an allowance.

"Warning function"
This warning function is a function for notifying the operator when the patient is in a dangerous position. For example, when the operating table S on which the patient is placed is operated, the head or the heart is more than the waist. When the posture is lowered, a warning is given to the operator.

  Specifically, the control unit of the operating table S determines whether or not the back plate is lowered with respect to the waist plate. That is, the angle of the waist plate and the angle of the back plate are calculated based on the values received from the encoders, and when the above formula is applied, the operation of the operation buttons 55a to 55e is electrically disconnected (no operation signal is transmitted or (Turn off the circuit temporarily). The operation button may be turned off, a sound may be output, or warning information may be displayed on the display unit. The warning information is an error number that is associated with detailed error information in advance. For example, the warning information may be a diagram indicating a failure location or language information such as “danger”.

"Failure display function"
This failure display function is a function for simply diagnosing a failure in the operating table and informing the user in some cases. Specifically, for example, when detecting a pump failure, the current flowing through the pump is measured, and if the pump fails, an overcurrent flows, so by comparing the measured value with a predefined specified value, It is determined whether or not there is a failure, and error (failure) information is displayed on the display unit of the remote control device.

  The abnormality information displays, for example, types of power supply abnormality, operation signal abnormality, drive system abnormality, and the like, and is preferably displayed for each color depending on the degree of risk.

"Log Function"
This log function is a function for recording an operation sequence by the remote control device as a history in order of date and time. When the predetermined storage amount is exceeded, the information may be moved by external communication, or that fact may be displayed on the display unit of the remote control device.

"External communication function"
This external communication function is, for example, a function for transmitting abnormality information and log information to the outside. For example, when a predetermined storage amount is exceeded, predetermined information is transmitted to a predetermined external device. is there.

  In addition, this embodiment is one form and is not limited to this form. For example, a generally well-known mechanism can be appropriately used as the mechanism of the tilt mechanism unit 30 of the present embodiment. Further, the amount of hydraulic oil supplied to the first cylinder device 35 may be at least part of the hydraulic oil discharged from the third cylinder device 25 to the tank T side. It is adjusted by appropriately controlling the valve device according to the diameter of the pipe to be connected.

  In addition, each cylinder device used in the present embodiment uses a double-acting cylinder, but a single-acting cylinder may be applied.
