Abstract

PURPOSE:To facilitate operation for various kinds of functions to achieve miniaturization and wt. reduction and to prevent erroneous operation, by mounting a control part for controlling the operating condition of a mode so as to correspond to a plurality of input means when one mode is indicated by a mode change-over means. CONSTITUTION:For example, when the righthand switch of the second stage is pressed, an operating signal is inputted to a CPU 12 through a KEY input part 11 and controlled by the CPU 12 to be given to the control part 6 of a radiation treatment apparatus 7 from a communication control part 14 and the stand 7a of the radiation treatment apparatus 7 is rotated in a CW direction. When one mode is indicated by the operation of a mode chang-over switch 5 blocked at every function, the operating condition to said mode is allowed to correspond to a plurality of operation switches 3, 4 by the CPU 12 to be displayed on an LED 2 and, therefore, desired operating conditions are selected from the operation switches 3, 4. As a result, plural operating conditions at every mode can be operated only by the operation switches 3, 4 and, therefore, the desired operating conditions can be easily selected and a portable operating device 1 can be miniaturized and reduced in weight while erroneous operation can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a hand-held operating device for a radiation therapy device used, for example, in a radiation therapy device, a radiation diagnostic device, or the like.

(Prior art) Conventionally, when treating a lesion in a human body using a radiation therapy device such as a linear particle accelerator, radiation is irradiated only to the lesion, and normal tissue around the lesion is irradiated with radiation. I try not to.

Therefore, the positioning of the linear particle accelerator is important;
With the patient placed on the bed, the operator sets the radiation irradiation direction (rotation angle of the pedestal) and the irradiation field, or moves the patient's bed to position the patient. In addition to this positioning, a switch is provided for each operation to operate the irradiation field lamp, optical distance system, etc. using the hand-held operating device.

FIG. 8 is a diagram showing a conventional hand-held operating device of this type.

In FIG. 8, the hand-held operating device 20 is operated for each operation to rotate the X-ray therapy device's gantry, rotate the aperture, open and close the aperture, move the top plate forward and backward, move it left and right and up and down, and operate the optical distance system, etc. A switch is provided. A hand-held operating device 30 as shown in FIG. 9 is also used. The hand-held operating device 30 shown in FIG. 9 divides some of the above-mentioned operations into blocks for each function, and is operated by mode switching. This hand-held operation device 30 has an operation switch 31 that allows one operation switch to have two sweeping functions in the operation of opening and closing the upper and lower apertures, moving the top plate forward and backward, and moving it left and right and up and down.

Further, the operable range on the hand-held operating device 20, 30 is limited to provide the minimum necessary functions, and other operating sections are placed on the bed or the head.

(Problems to be Solved by the Invention) However, the above-mentioned conventional hand-held operating device has the following problems. That is, the hand-held operating device 20.30
Since there is an operation switch for each operation,
The hand-held controller 20.30 has become larger.

The problem is that it is complicated and has poor operability. Further, when each function is divided into blocks and the mode is changed as shown in FIG. 9, there is a problem that the operation is complicated because there are multiple nameplates on the operation switch, which may lead to erroneous operation.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a hand-held operating device for an X-ray therapy apparatus that can easily operate each function, can be made smaller and lighter, and can prevent erroneous operation.

In response to the interior light blinking, FI is applied to LEDs 2b to 2e in order.
ELD, 5POT, O, D, I, and ROOM are displayed. Therefore, for example, when turning on a spotlight, 5
By pressing the operation switches 3c at both ends, which are displayed as POT, the spotlight of the radiation therapy apparatus 7 is turned on, and the spotlight is displayed on the LED Zc.

In such an embodiment, each function is operated by the mode changeover switch 5 which is divided into blocks, and when one mode is specified by the mode changeover switch 5, the operation conditions for the mode are set by the CPU 12. Since it corresponds to the operation switches 3 and 4 and is displayed correspondingly to the LED 2, a desired operation condition is selected from the operation switch 3.4. As a result, a plurality of operating conditions for each mode can be operated using only the operating switch 3.4, so desired operating conditions can be easily selected, the hand-held operating device 1 can be made smaller and lighter, and erroneous operation can be prevented.

In addition, in the embodiment, the LED 2 is provided to visually display the correspondence between the modes switched to the operating switches 3 and 4, so that the operating conditions of each operating switch 3 and 4 can be clearly understood, and malfunctions can be prevented. It can be prevented.

Further, switch 3b is continued to be pressed until the minus digit becomes 0, and when it becomes 0, switch 4b is pressed to confirm the minus digit and the automatic setting is completed. When these series of operations are displayed in chronological order, it becomes as shown in FIG. 6(c). Note that only one of the displays shown in Figure 6(C) is L.
Displayed on ED2b. When automatic setting data for rotating the pedestal 7a is sent to the radiation therapy apparatus 7 through such an operation, the pedestal is automatically rotated by 180 degrees. Therefore, the same effects as in the first embodiment described above can be obtained even in automatic setting by such mode switching.

Next, a third embodiment will be described. FIG. 7 is a diagram showing a display for operating the type of accessory on the hand-held operating device l. In other words, accessories include wedge filters,
There is an electron beam cone, etc., which is used to control the radiation when performing radiation therapy on a patient. As shown in FIG. 7, when the mode is changed using the mode selector switch 5, 1, D information, 1. D NAME and l
.

D number and cone size (size that controls radiation dose)
and accessories (20X 20) are LED2a~2
It is displayed on e.

Therefore, if you want to know which accessory to use in the treatment room, you can use the hand-held operating device to know the type of accessory that is appropriate for each patient, improving the convenience of operation.

Note that the present invention is not limited to the embodiments described above, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
