Summary of the Invention
Problems to be Solved by the Invention
[0004] In radiation therapy, it is necessary to accurately position the patient with respect to the radiation irradiation portion. For this reason, a radiation therapy bed on which the patient to be treated is placed is equipped with a mechanism capable of mechanically controlling the horizontal position, vertical position, inclination, etc. Also, in a radiation therapy bed, prevention of failures and misoperations is extremely important. This is because the repair cost is high, and the time until the repair is completed has a great impact on the treatment plan.
[0005] One of the causes of malfunctions or errors in radiation therapy beds is the dropping of the remote controller. The remote controller is connected to the radiation therapy bed, for example, by a coiled cord. The operator can operate the remote controller from any standing position to control the position and tilt of the radiation therapy bed. However, if the operator drops the remote controller and it falls, hitting the floor with its control unit, it can cause malfunctions or errors.
[0006] Therefore, the present invention aims to prevent malfunctions and failures caused by dropping the remote controller. [Means for solving the problem]
[0007] To achieve the above objective, one representative radiotherapy apparatus of the present invention comprises a radiotherapy bed on which a patient to be treated for radiotherapy is placed, a radiation irradiation unit for irradiating the patient with radiation, and a remote controller having an operation unit for receiving operations related to the position control of the radiotherapy bed, wherein the remote controller is provided with bumper members that protrude from both ends in the longitudinal direction of the operation surface on which the operation unit is provided. [Effects of the Invention]
[0008] According to the present invention, it is possible to prevent malfunctions and failures caused by dropping the remote controller. Other problems, configurations, and effects will be clarified by the following description of embodiments. [Brief explanation of the drawing]
[0009] [Figure 1] Six-view drawing of a remote controller for a radiation therapy device. [Figure 2] Perspective view of a remote controller for a radiation therapy device. [Figure 3] Diagram illustrating a radiation therapy bed (Part 1) [Figure 4] Diagram illustrating a radiation therapy bed (part 2) [Figure 5]Diagram illustrating the locking mechanism of the remote controller. [Modes for carrying out the invention]
[0010] The following examples will be described with reference to the drawings. [Examples]
[0011] Figure 1 is a six-view drawing of the remote controller of the radiation therapy device. Figure 2 is a perspective view of the remote controller of the radiation therapy device. Figures 3 and 4 are explanatory diagrams of the radiation therapy bed. The radiation therapy device comprises a radiation therapy bed 100 on which the patient receiving radiation therapy is placed, and a radiation irradiation unit that irradiates the patient with radiation.
[0012] The radiation therapy bed 100 comprises, for example, a base member, a first bed member, and a second bed member. The base member is provided in contact with the floor. The first bed member is installed on the base member and its position relative to the base member is mechanically controllable. The second bed member is installed on the first bed member and its position relative to the first bed member is mechanically controllable.
[0013] The second bed member is movable in a direction (Y) that brings the patient placed on the second bed member into the radiation therapy device and in a direction that brings the patient out of the radiation therapy device. Furthermore, the second bed member can be adjusted in the direction of rotation (roll) around the direction of arrival and in the angle of inclination (pitch) with respect to the direction of arrival. The interior of a radiation therapy device refers to the area where the radiation irradiation unit delivers radiation, such as the inside of the gantry.
[0014] The first bed member is movable in the horizontal direction (X) and the vertical direction (Z) relative to the floor. Here, the horizontal movement of the first bed member is movement in a direction perpendicular to the loading direction (Y) of the second bed member. Similarly, the vertical movement of the first bed member is movement in a direction perpendicular to the loading direction (Y) of the second bed member.
[0015] The remote controller 141 is connected to the radiotherapy bed 100 by a coiled cord and has an operation unit 143 that receives operations related to the position control of the radiotherapy bed 100. The remote controller 141 includes bumper members 145 that protrude from both ends in the longitudinal direction of the operation surface provided with the operation unit 143 toward the operation surface. The bumper members 145 protect the operation unit 143 when the remote controller 141 drops. For example, even if the operator drops the remote controller 141, before the operation unit 143 of the remote controller 141 collides with the floor surface, the bumper members 145 hit the floor surface and absorb the impact, preventing malfunctions and incorrect operations of the remote controller 141.
[0016] The remote controller 141 has a connector 142 connected to the coiled cord at one end in the longitudinal direction. And the bumper member 145 provided at the other end in the longitudinal direction has a shape that also serves as a locking member for locking to the radiotherapy bed 100.
[0017] Specifically, the bumper member 145 that also serves as a locking member is an elastic body having a hole 146. Therefore, the bumper member 145 can deform when dropped, absorb the impact, and prevent damage to the remote controller 141. Furthermore, the remote controller 141 can be locked to the radiotherapy bed 100 by inserting the hole 146 through a convex portion 140 provided on the radiotherapy bed 100.
[0018] Furthermore, the remote controller 141 includes an accidental operation prevention button 144 along the longitudinal direction on a surface different from the operation surface provided with the operation unit 143. The operation unit 143 is composed of buttons, levers, etc. that receive various operations for the radiotherapy bed 100. The operations received by the operation unit 143 include horizontal movement and vertical movement of the first bed member, movement and angle adjustment of the second bed member, etc. The operation unit 143 receives at least some operations on the condition that the accidental operation prevention button 144 is being pressed.
[0019] The bumper member 145 is detachable from the remote controller 141. When the remote controller 141 falls and the bumper member 145 is damaged to protect the remote controller 141 itself, the repair can be completed by simply replacing the damaged bumper member 145, and the repair cost and time required can be suppressed. The two bumper members 145 provided at both longitudinal ends of the remote controller 141 may have different shapes or the same shape. Since the bumper member 145 on the connector 142 side does not require the function as a locking member, there is a high degree of freedom in shape and material. On the other hand, if the shapes of the bumper member 145 on the connector 142 side and the bumper member 145 that also serves as a locking member are the same, there is an advantage that either one can be replaced with the same spare part even if it is damaged. Note that the attachment of the bumper member 145 to the remote controller 141 may use screw fastening or the like.
[0020] Also, although the bumper member 145 protrudes from both longitudinal ends of the operation surface with respect to the operation surface, it is desirable to have an inclination in a direction away from the operation unit 143. This is because by providing the bumper member 145 so as to spread from the operation unit 143, the visibility and operability of the operation unit 143 can be ensured. The bumper member 145 protrudes from both longitudinal ends of the remote controller 141 and is not provided on the longitudinal sides. Therefore, the operator can grip and operate the remote controller 141 without being obstructed by the bumper member 145. And since the accidental operation prevention button 144 is provided on this longitudinal side, the accidental operation prevention button 144 can be naturally pressed in a state where the remote controller 141 is held, and the simultaneous operation of the accidental operation prevention button 144 and the operation unit 143 is easy.
[0021] In FIG. 1, a cross-sectional view of a rotation switch that is a part of the operation unit 143 is shown. Since the rotation switch is mechanical and easily broken, the protection by the bumper member 145 is particularly effective.
[0022] Figure 3 shows the state in which the operator is using the remote controller 141, and Figure 4 shows the state in which the remote controller 141 is attached to the protrusion 140 of the radiation therapy bed 100. As shown in Figure 3, the radiation therapy bed 100 has a recess for housing the remote controller 141, and the recess has a protrusion 140. When the remote controller 141 is not in use, the operator will hang the remote controller 141 in place by inserting the protrusion 140 through the hole 146 of the bumper member 145.
[0023] Figure 5 shows a cross-section of the remote controller 141 in the state shown in Figure 4. As shown in Figure 5, the remote controller 141 is secured to the radiation therapy bed 100 by inserting the protrusion 140 through the hole 146 of the bumper member 145.
[0024] Figures 3 to 5 show an example in which a protrusion is provided at a fixed position on the radiation therapy bed 100 and locking is achieved by passing it through the hole 146 of the bumper member 145. However, locking may be achieved in other ways. For example, a handrail-like outer edge member may be provided in a predetermined range on the radiation therapy bed 100, and the bumper member 145 may be made hook-shaped and hooked onto the outer edge member.
[0025] As described above, the disclosed radiotherapy apparatus comprises a radiotherapy bed 100 on which a patient to be treated for radiotherapy is placed, a radiation irradiation unit for irradiating the patient with radiation, and a remote controller 141 having an operation unit 143 for receiving operations related to the position control of the radiotherapy bed, wherein the remote controller 141 is provided with bumper members 145 that protrude from both ends in the longitudinal direction of the operation surface on which the operation unit 143 is provided. Therefore, the bumper member 145 protects the operating unit 143 when the remote controller 141 is dropped, preventing malfunctions and failures.
[0026] Furthermore, the remote controller 141 is connected to the radiation therapy bed by a cord extending from one end in the longitudinal direction, and the bumper member 145 provided at the other end in the longitudinal direction also serves as a locking member for securing it to the radiation therapy bed 100. Furthermore, the bumper member 145, which also serves as the locking member, is an elastic body having a hole 146, and the remote controller 141 can be locked to the radiotherapy bed 100 by inserting the hole 146 into a protrusion 140 provided on the radiotherapy bed 100. By achieving both locking and protection of the operating part 143 with the same component, cost reduction and improved functionality can be achieved.
[0027] Furthermore, the remote controller 141 is provided with a malfunction prevention button 144 on a surface different from the operating surface, along the longitudinal direction, and the operating unit 143 accepts at least some operations on the condition that the malfunction prevention button 144 is pressed. Therefore, it is possible to improve operability and prevent accidental operation.
[0028] The bumper member 145 protects the operating unit 143 by making contact with the floor surface before the operating unit 143 collides with the floor surface when the remote controller 141 falls, thereby contributing to the prevention of malfunction or failure of the remote controller. Furthermore, the bumper member 145 is detachable from the remote controller 141. Therefore, even if the bumper component 145 is damaged due to a fall, it can be repaired quickly and at low cost. The two bumper members 145, each provided at both ends in the longitudinal direction, may have the same shape. The replacement of the bumper component 145 can be performed more efficiently.
[0029] Furthermore, the bumper member 145 protrudes from both ends in the longitudinal direction of the operating surface relative to the operating surface and is inclined in a direction away from the operating part 143. This ensures the visibility and operability of the control unit 143.
[0030] It should be noted that the present invention is not limited to the embodiments described above, and various modifications are included. For example, the embodiments described above are explained in detail for the purpose of clearly illustrating the present invention, and are not necessarily limited to those having all the configurations described. Furthermore, it is possible to replace or add configurations, not just delete them. [Explanation of Symbols]
