Description

[Technical Field]

[0001] The present invention relates to an X-ray imaging apparatus. [Background technology]

[0002] BACKGROUND ART Conventionally, an X-ray imaging apparatus is known (see, for example, Patent Document 1).

[0003] The above-mentioned Patent Document 1 discloses an X-ray imaging device including a movable tabletop on which a subject is placed, an operation unit provided on the side of the tabletop, and a movement mechanism that moves the position of the operation unit when the tabletop moves. When the tabletop is tilted, the movement mechanism tilts the operation unit in the direction opposite to the tilt direction of the tabletop by the angle of the tabletop tilt. In other words, when the tabletop is tilted, the movement mechanism returns the tilt angle of the operation unit, which has changed with the tilt of the tabletop, to the tilt angle before the tilt operation (horizontal).

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-99613 Summary of the Invention [Problem to be solved by the invention]

[0005] In the X-ray imaging device described in Patent Document 1, the operating unit is provided so as to protrude from the longitudinal side of the tabletop. When performing a procedure using the X-ray imaging device, the surgeon stands on the longitudinal side of the tabletop on which the operating unit is provided and operates the operating unit while performing the procedure. However, in the X-ray imaging device described in Patent Document 1, when the surgeon leans over the tabletop to approach the subject and perform the procedure, the operating unit protrudes from the side of the tabletop, which may cause interference between the operating unit and the surgeon's abdomen, etc. This poses a problem in that the operating unit interferes with the procedure. Therefore, it is desirable to prevent the operating unit from interfering with the procedure.

[0006] The present invention has been made to solve the above-mentioned problems, and one object of the present invention is to provide an X-ray imaging device that can prevent the operating unit from interfering with treatment. [Means for solving the problem]

[0007] In one aspect of the present invention, an X-ray imaging device includes an X-ray irradiation unit that irradiates a subject with X-rays, an X-ray detection unit that detects X-rays that have passed through the subject, a tabletop on which the subject rests, and an operation unit that is provided on the side of the tabletop and accepts input operations related to X-ray imaging, and the operation unit is configured to be movable between an operation position and a retracted position in which the protruding length of the operation unit from the side of the tabletop is relatively smaller than the protruding length at the operation position. [Effects of the Invention]

[0008] In the X-ray imaging device according to one aspect described above, the operation unit is configured to be movable between an operation position and a retracted position, in which the protruding length of the operation unit from the side surface of the tabletop is relatively smaller than the protruding length at the operation position. This allows the operation unit located at the operation position to be moved to the retracted position, in which the protruding length is relatively smaller than the protruding length at the operation position, when, for example, the surgeon leans over the tabletop to approach the subject and perform a treatment. Because the protruding length of the operation unit at the retracted position is relatively smaller than the protruding length at the operation position, the operation unit at the retracted position is less likely to interfere with the surgeon's abdomen, etc., than the operation unit at the operation position. Therefore, during a treatment, the operation unit located at the retracted position can be more likely to interfere with the surgeon's abdomen, etc., than the operation unit located at the operation position. As a result, the operation unit can be prevented from interfering with the treatment. [Brief explanation of the drawings]

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0011] [First embodiment] (Configuration of X-ray equipment) The configuration of an X-ray imaging apparatus 100 according to this embodiment will be described with reference to FIGS.

[0012] As shown in Figure 1, the X-ray imaging device 100 includes a tabletop 1, an X-ray irradiation unit 2, an X-ray detection unit 3, an imaging unit movement unit 4, a display unit 5, an operation unit 6, an operation unit movement unit 7 (see Figure 3), an invalidation unit 8 (see Figure 2), and an imaging control unit 9 (see Figure 2).

[0013] A subject 101 is placed on the tabletop 1. While the subject 101 is placed on the tabletop 1, an X-ray is taken of the subject 101 and an operator performs a procedure on the subject 101. The tabletop 1 is configured to be movable by a tabletop moving unit 11 including a driving unit such as a motor, based on the control of an imaging control unit 9.

[0014] In this specification, the vertical direction is defined as the Z direction, the upward direction as the Z1 direction, and the downward direction as the Z2 direction. Two mutually orthogonal horizontal directions are defined as the X direction and the Y direction. One side of the X direction is defined as the X1 direction, and the other side as the X2 direction. One side of the Y direction is defined as the Y1 direction, and the other side as the Y2 direction. In the example shown in FIG. 1, the subject 101 is placed so that the head of the subject 101 faces the X1 direction. That is, when the top board 1 is in a horizontal position, the X direction is the longitudinal direction of the top board 1. Furthermore, when the top board 1 is in a horizontal position, the Y direction is the lateral direction of the top board 1.

[0015] The X-ray irradiator 2 irradiates the subject 101 with X-rays. The X-ray irradiator 2 includes an X-ray tube 21 that irradiates X-rays when a voltage is applied thereto. The X-ray tube 21 is configured such that the voltage applied to the X-ray tube 21 is controlled by the imaging controller 9, thereby controlling the X-rays to be irradiated.

[0016] The X-ray detection unit 3 detects X-rays that have passed through the subject 101. Then, the X-ray detection unit 3 outputs a detection signal based on the detected X-rays. The X-ray detection unit 3 includes, for example, an FPD (Flat Panel Detector).

[0017] The imaging unit moving unit 4 movably holds the X-ray irradiator 2 and the X-ray detector 3. Specifically, the imaging unit moving unit 4 supports the X-ray irradiator 2 and the X-ray detector 3 so that they face each other across the tabletop 1 on which the subject 101 rests. The imaging unit moving unit 4 also supports the X-ray irradiator 2 and the X-ray detector 3 so that their positions and angles relative to the subject 101 can be changed. The imaging unit moving unit 4 also supports the distance between the X-ray irradiator 2 and the X-ray detector 3 so that it can be changed. In other words, the imaging unit moving unit 4 moves the X-ray irradiator 2 and the X-ray detector 3 to perform X-ray imaging of the subject 101 from various positions and angles.

[0018] The display unit 5 is, for example, a monitor such as a liquid crystal display, etc. The display unit 5 displays the X-ray image generated by the imaging control unit 9.

[0019] The operation unit 6 is configured to receive input operations related to X-ray imaging. Specifically, the operation unit 6 is configured to receive input operations for operating the X-ray imaging device 100. The operation unit 6 receives, for example, an operation to move the tabletop 1 and the imaging unit moving unit 4. The operation unit 6 receives, for example, an operation to irradiate X-rays when X-ray imaging is performed on the subject 101. The operation unit 6 also receives input operations for executing control by the imaging control unit 9.

[0020] The operation unit 6 is provided on a side surface 10 of the tabletop 1. The operation unit 6 is configured to be movable between an operation position (see FIG. 4) and a retracted position (see FIG. 4) in which the protruding length of the operation unit 6 from the side surface 10 of the tabletop 1 is relatively smaller than the protruding length in the operation position. The operation unit 6 is configured to be movable between the operation position and the retracted position by rotating relative to the tabletop 1. Specifically, the operation unit 6 moves from the operation position to the retracted position by rotating downward, and moves from the retracted position to the operation position by rotating upward. The configuration of the operation unit 6, the rotation of the operation unit 6, the operation position, and the retracted position will be described in detail later.

[0021] The operation unit moving unit 7 (see FIG. 3) movably holds the operation unit 6. The operation unit moving unit 7 is configured to rotate the operation unit 6 relative to the tabletop 1, thereby moving the operation unit 6 between an operation position and a retracted position where the protruding length of the operation unit 6 from the side surface 10 of the tabletop 1 is relatively smaller than the protruding length at the operation position. The operation unit moving unit 7 is also configured to slide the operation unit 6 relative to the tabletop 1 along the longitudinal direction of the tabletop 1. The configuration of the operation unit moving unit 7 will be described later.

[0022] The invalidation unit 8 (see FIG. 2) is configured to invalidate input operations related to X-ray photography on the operation unit 6 and to cancel the invalidation of input operations related to X-ray photography on the operation unit 6. Specifically, the invalidation unit 8 is configured to invalidate input operations related to X-ray photography on the operation unit 6 including the operation lever 61 based on the operation unit 6 being moved to the retracted position. Furthermore, the invalidation unit 8 is configured to cancel the invalidation of input operations related to X-ray photography on the operation unit 6 including the operation lever 61 based on the operation unit 6 being moved to the operating position.

[0023] The invalidation unit 8 (see FIG. 2) includes an invalidation detection unit 80 (see FIG. 2) and an invalidation control unit 81 (see FIG. 2). The invalidation detection unit 80 is configured to detect the operation unit 6. The invalidation detection unit 80 is, for example, a push switch. As shown in FIG. 4, when the operation unit 6 is positioned at the retracted position, the invalidation detection unit 80 detects that the operation unit 6 is at the retracted position by being pressed by the operation unit 6. Furthermore, when the operation unit 6 positioned at the retracted position is rotated and moved from the retracted position, the invalidation detection unit 80 does not detect that the operation unit 6 is at the retracted position by releasing the pressure from the operation unit 6. The invalidation detection unit 80 is provided on the bottom surface 71a (see FIG. 4) of the engagement member 71 of the operation unit movement unit 7.

[0024] 2, the invalidation control unit 81 includes, for example, a microcomputer. The invalidation control unit 81 is configured to invalidate input operations related to X-ray imaging to the operation unit 6 including the operation lever 61 based on detection of the operation unit 6 by the invalidation detection unit 80, and to cancel the invalidation of input operations related to X-ray imaging to the operation unit 6 including the operation lever 61 based on the invalidation detection unit 80 not detecting that the operation unit 6 is in the retracted position. Specifically, the invalidation control unit 81 invalidates input operations related to X-ray imaging to the operation unit 6 including the operation lever 61 based on the invalidation detection unit 80 detecting that the operation unit 6 is in the retracted position as a result of the operation unit 6 being located in the retracted position. Furthermore, the invalidation control unit 81 cancels the invalidation of input operations related to X-ray imaging to the operation unit 6 including the operation lever 61 based on the invalidation detection unit 80 not detecting that the operation unit 6 is in the retracted position as a result of the operation unit 6 moving from the retracted position.

[0025] The imaging control unit 9 is a computer including, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory), etc. The imaging control unit 9 controls each unit of the X-ray imaging apparatus 100, controls the X-ray irradiation unit 2 to irradiate X-rays based on X-ray conditions, controls the generation of X-ray images, and controls the display unit 5 to display the X-ray images, by the CPU executing a predetermined control program.

[0026] (Configuration of the operation section) The configuration of the operation unit 6 will be described with reference to FIGS.

[0027] 1 and 3, the operation unit 6 includes a first operation unit 6a, a second operation unit 6b, and a third operation unit 6c. The first operation unit 6a, the second operation unit 6b, and the third operation unit 6c are arranged along the longitudinal direction of the tabletop 1. The first operation unit 6a, the second operation unit 6b, and the third operation unit 6c are each configured as separate units. In this embodiment, the first operation unit 6a, the second operation unit 6b, and the third operation unit 6c are configured to rotate integrally with respect to the tabletop 1, so that they are moved integrally between an operation position and a retracted position in which the protruding length of the operation unit 6 from the side surface 10 of the tabletop 1 is relatively shorter than the protruding length at the operation position.

[0028] The first operation unit 6a includes an operation panel 60 (see FIG. 3), an operation lever 61, and an operation button 62. When in the operation position, the operation lever 61 is disposed so as to protrude upward (in the Z1 direction) from the operation panel 60. The operation lever 61 and the operation button 62 are used by the surgeon to perform input operations. The operation lever 61 and the operation button 62 are configured to receive input operations related to X-ray imaging. The operation lever 61 is configured to receive input operations, for example, regarding the movement of the tabletop 1 and the imaging unit moving unit 4. The operation button 62 is configured to receive input operations related to the irradiation of X-rays by the X-ray irradiation unit 2. The shapes and uses of the operation lever 61 and the operation button 62 are not particularly limited. Although two operation levers 61 and one operation button 62 are illustrated in FIGS. 1 and 3, the first operation unit 6a has no particular limitation on the number of operation levers 61 and operation buttons 62.

[0029] The second operation unit 6b includes a touch panel 63. The second operation unit 6b is configured to receive input operations by the operator to operate the X-ray imaging apparatus 100. The second operation unit 6b is configured to receive input operations, for example, for setting X-ray conditions and changing the layout of the display unit 5. As shown in FIG. 3, a length 69b in the short side direction (Y direction) of the second operation unit 6b is longer than a length 69a in the short side direction (Y direction) of the first operation unit 6a and a length 69c in the short side direction (Y direction) of the third operation unit 6c.

[0030] The third operation unit 6c includes an operation panel 60, an operation lever 61, and an operation button 62. When in the operation position, the operation lever 61 is provided so as to protrude upward (in the Z1 direction) from the operation panel 60. The operation lever 61 and the operation button 62 are used by the surgeon to perform input operations. The operation lever 61 and the operation button 62 are configured to receive input operations, such as changing the X-ray image displayed on the display unit 5. The shapes and uses of the operation lever 61 and the operation button 62 are not particularly limited. Although one operation lever 61 and two operation buttons 62 are illustrated in FIGS. 1 and 3 for the third operation unit 6c, the numbers of the operation levers 61 and the operation buttons 62 are not particularly limited.

[0031] (Operating position and evacuation position) The operation position and the retracted position will be described with reference to Fig. 4. Fig. 4 is a schematic side view showing the operation unit 6, operation unit moving unit 7, and tabletop 1 as viewed from the X1 direction. The operation unit 6 shown in the upper diagram of Fig. 4 is located at the operation position. The operation unit 6 shown in the lower diagram of Fig. 4 is located at the retracted position.

[0032] The operation unit 6 is configured to move between the operation position and the retracted position by rotating 90 degrees or more relative to the tabletop 1. In this embodiment, the operation unit 6 moves between the operation position and the retracted position by rotating 90 degrees relative to the tabletop 1. The operation unit 6 moves from the operation position to the retracted position by rotating approximately 90 degrees in a direction in which the vertical component of the operating lever 61 becomes smaller. Note that the operation unit 6 may also be configured to move between the operation position and the retracted position by rotating approximately 90 degrees or more relative to the tabletop 1.

[0033] As shown in the upper diagram of FIG. 4, the operating position is a position of the operating unit 6 where the operating panel 60 of the operating unit 6 faces upward and is arranged substantially horizontally. At the operating position, the operating lever 61 and the operating button 62 included in the first operating unit 6a and the third operating unit 6c protrude vertically (in the Z1 direction) from the operating panel 60. At the operating position, the display surface of the touch panel 63 included in the second operating unit 6b faces upward. The position of the uppermost end 61a of the operating lever 61 at the operating position is higher than the position of the uppermost end 61a of the operating lever 61 at the retracted position.

[0034] Furthermore, when the operation unit 6 is located at the operation position, the invalidation detection unit 80 does not detect that the operation unit 6 is at the retracted position because it is not being pressed by the operation unit 6. Therefore, the invalidation control unit 81 cancels the invalidation of input operations related to X-ray imaging to the operation unit 6 including the operation lever 61 located at the operation position.

[0035] During treatment, the surgeon stands on the side surface 10 in the longitudinal direction (Y1 direction) of the tabletop 1 and operates the operation unit 6 located at the operation position. The operation unit 6 located at the operation position is arranged so that the operation panel 60 faces upward and is approximately horizontal. The operation unit 6 located at the operation position accepts input operations by the surgeon using the operation lever 61, operation buttons 62, and touch panel 63 included in the operation unit 6.

[0036] As shown in the lower diagram of FIG. 4, the protruding length of the operation unit 6 from the side surface 10 of the tabletop 1 in the retracted position is relatively smaller than the protruding length in the operation position. The retracted position is below the position of the side surface 10 of the tabletop 1 where the operation unit 6 is provided in the operation position. The retracted position is a position of the operation unit 6 where the operation panel 60 of the operation unit 6 faces the Y1 direction and is perpendicular to the horizontal direction (Z direction). The retracted position is a position where the operation unit 6 located in the operation position is rotated approximately 90 degrees with respect to the tabletop 1. In the retracted position, the operation lever 61 and the operation button 62 included in the first operation unit 6a and the third operation unit 6c protrude from the operation panel 60 in the Y1 direction. In the retracted position, the display surface of the touch panel 63 included in the second operation unit 6b faces sideways (Y1 direction). The position of the uppermost end 61a of the operating lever 61 in the retracted position is lower than the position of the uppermost end 61a of the operating lever 61 in the operating position.

[0037] Furthermore, when the operation unit 6 is located at the retracted position, the invalidation detection unit 80 detects that the operation unit 6 is at the retracted position because the operation unit 6 is being pressed. Therefore, the invalidation control unit 81 invalidates input operations related to X-ray imaging to the operation unit 6, including the operation lever 61 located at the retracted position. Therefore, the operation unit 6 located at the retracted position does not accept input operations by the operator to the operation lever 61, operation button 62, and touch panel 63 included in the operation unit 6.

[0038] (Configuration of the operation unit movement part) The configuration of the operation unit moving unit 7 will be described with reference to Fig. 4. As shown in Fig. 4, the operation unit moving unit 7 includes a guide unit 70, an engagement member 71, a rotational connection unit 72, and an operation position maintaining unit 73.

[0039] The guide unit 70 is configured to allow the operation unit 6 to slide relative to the tabletop 1 along the longitudinal direction (X direction) of the tabletop 1. The guide unit 70 is, for example, a guide rail. The surgeon can manually slide the operation unit 6 along the longitudinal direction (X direction) of the tabletop 1 via the guide unit 70.

[0040] The engaging member 71 is configured to engage with the guide portion 70. The engaging member 71 is, for example, a hook. Note that the engaging member 71 is not limited to a hook, and is not particularly limited as long as it is a member that can slide via the guide portion 70 while engaging with the guide portion 70.

[0041] The pivotal connection part 72 is configured to pivotally connect the operation unit 6 to the tabletop 1. The pivotal connection part 72 is, for example, a hinge that is pivotable about an axis 79, and connects the engagement member 71 and the operation unit 6. The pivotal connection part 72 is attached to the engagement member 71. Specifically, one wing of the pivotal connection part 72 (not shown) is attached to the outer surface 71b of the engagement member 71, and the other wing (not shown) is attached to the side surface 60a on the tabletop side (Y2 direction side) of the operation unit 6 that is located at the operation position. The operation unit 6 moves between the operation position and the retracted position by pivoting via the pivotal connection part 72.

[0042] The operation position maintaining unit 73 is configured to maintain the operation unit 6 in the operation position. The operation position maintaining unit 73 is, for example, a rod-shaped member that detachably connects the outer surface 71b of the engagement member 71 and the bottom surface 60b of the operation unit 6. As shown in the upper diagram of FIG. 4 , the operation position maintaining unit 73 connects the outer surface 71b of the engagement member 71 and the bottom surface 60b of the operation unit 6, thereby restricting rotational movement of the operation unit 6 located in the operation position. In other words, the operation position maintaining unit 73 acts like a so-called stop bar, thereby maintaining the operation unit 6 in the operation position. Furthermore, when the surgeon removes the operation position maintaining unit 73 that connects the outer surface 71b of the engagement member 71 and the bottom surface 60b of the operation unit 6, the restriction on rotational movement of the operation unit 6 located in the operation position is released.

[0043] (Movement between the operating position and the retracted position by rotating the operating part) Referring to FIG. 4, the movement of the operating unit 6 between the operating position and the retracted position due to rotation will be described.

[0044] 4, the operating position maintaining portion 73 restricts the rotational movement of the operating portion 6 located at the operating position by connecting the outer surface 71b of the engaging member 71 with the bottom surface 60b of the operating portion 6. The operating portion 6 is maintained at the operating position.

[0045] 4, the surgeon removes the operation position maintaining part 73 from the outer surface 71b of the engaging member 71 and the bottom surface 60b of the operation unit 6, thereby releasing the restriction on the rotational movement of the operation unit 6 by the operation position maintaining part 73. Therefore, the operation unit 6 rotates downward due to its own weight, and moves from the operation position to the retracted position.

[0046] Then, the operating unit 6, which is located in the retracted position, is rotated upward by the surgeon to move it from the retracted position to the operating position, and the operating position maintaining unit 73 is attached to the outer surface 71b of the engaging member 71 and the bottom surface 60b of the operating unit 6, so that the rotational movement of the operating unit 6 located in the operating position is restricted by the operating position maintaining unit 73. As a result, the operating unit 6 is maintained in the operating position, as shown in the upper diagram of FIG.

[0047] (Effects of the first embodiment) In the first embodiment, the following effects can be obtained.

[0048] As described above, the first embodiment includes an operation unit 6 that is provided on the side surface 10 of the tabletop 1 and accepts input operations related to X-ray imaging. The operation unit 6 is configured to be movable between an operation position and a retracted position where the protruding length of the operation unit 6 from the side surface 10 of the tabletop 1 is relatively shorter than the protruding length at the operation position. This allows the operation unit 6 located at the operation position to be moved to the retracted position where the protruding length is relatively shorter than the protruding length at the operation position, for example, when the surgeon leans over the tabletop 1 to approach the subject 101 and perform a treatment. Because the protruding length of the operation unit 6 at the retracted position is relatively shorter than the protruding length at the operation position, the operation unit 6 at the retracted position is less likely to interfere with the surgeon's abdomen, etc., than the operation unit 6 at the operation position. Therefore, during treatment, the operation unit 6 located at the retracted position can be more likely to interfere with the surgeon's abdomen, etc., than the operation unit 6 located at the operation position. As a result, the operation unit 6 can be prevented from interfering with the treatment.

[0049] Furthermore, in the above embodiment, the following additional effects can be obtained by configuring as follows.

[0050] That is, in the first embodiment, as described above, the operation unit 6 includes an operation panel 60 and an operation lever 61 that protrudes from the operation panel 60 and accepts input operations related to X-ray imaging. The operation unit 6 is configured to be movable between an operation position and a retracted position by rotating with respect to the tabletop 1. This allows the operation unit 6, including the operation lever 61 protruding from the operation panel 60, to be rotated and moved to the retracted position. The operation unit 6 positioned in the retracted position can reduce the amount of upward protrusion of the operation lever 61 protruding from the operation unit 6 compared to the operation unit 6 positioned in the operation position, thereby preventing interference between the operation lever 61 and the surgeon's elbow or the like during treatment. As a result, the operation unit 6 can be further prevented from interfering with treatment.

[0051] Furthermore, in the first embodiment, as described above, the disabling unit 8 is provided which disables input operations related to X-ray imaging to the operation unit 6 based on the operation unit 6 being moved to the retracted position, and which cancels the disablement of input operations related to X-ray imaging to the operation unit 6 based on the operation unit 6 being moved to the operation position. This allows the surgeon to perform input operations to the operation unit 6 located at the operation position, and even if the surgeon touches the operation unit 6 located at the retracted position, the input operations related to X-ray imaging to the operation unit 6 are disabled, so it is possible to reliably prevent the X-ray imaging apparatus 100 from performing unintended operations due to the surgeon's touching the operation unit 6.

[0052] Furthermore, in the first embodiment, as described above, the operation unit 6 moves from the operation position to the retracted position by rotating downward, and moves from the retracted position to the operation position by rotating upward. As a result, the operation unit 6 located at the operation position is rotated downward to move to the retracted position, so that the operation unit 6 at the retracted position can be effectively prevented from interfering with the treatment, and the operation unit 6 located at the retracted position is rotated upward to move to the operation position, so that the surgeon can easily perform input operations on the operation unit 6 at the operation position.

[0053] Furthermore, in the first embodiment, as described above, the position of the uppermost end 61a of the operation lever 61 in the retracted position is lower than the position of the uppermost end 61a of the operation lever 61 in the operation position. As a result, when the operation unit 6 is moved to the retracted position and the surgeon leans over the tabletop 1 to approach the subject 101 and perform treatment, interference between the operation lever 61 protruding from the operation unit 6 and the surgeon's elbow or the like can be effectively prevented compared to when the operation unit 6 remains in the operation position. As a result, it is possible to effectively prevent the operation unit 6 from interfering with the treatment.

[0054] Furthermore, in the first embodiment, as described above, the operation position maintaining unit 73 is provided to maintain the operation unit 6 in the operation position, thereby making it possible to reliably maintain the operation unit 6 in the operation position.

[0055] Furthermore, as described above, the first embodiment includes a guide portion 70 that slides the operation unit 6 relative to the table top 1 along the longitudinal direction of the table top 1, an engagement member 71 that engages with the guide portion 70, and a pivotal connection portion 72 that rotatably connects the operation unit 6 to the table top 1, and the pivotal connection portion 72 is attached to the engagement member 71. As a result, because the pivotal connection portion 72 is attached to the sliding engagement member 71, even when the operation unit 6 slides along the longitudinal direction of the table top 1, the operation unit 6 can be rotated via the pivotal connection portion 72 at the slid position and moved to the retracted position.

[0056] Furthermore, in the first embodiment, as described above, the operation unit 6 moves between the operation position and the retracted position by rotating by 90 degrees or more with respect to the tabletop 1. As a result, the operation unit 6 positioned at the retracted position can reduce the amount of upward protrusion of the operation lever 61 protruding from the operation unit 6 compared to the operation unit 6 positioned at the operation position, and therefore, interference between the operation lever 61 and the surgeon's elbow or the like during treatment can be more effectively prevented. As a result, the operation unit 6 can be more effectively prevented from interfering with treatment.

[0057] [Second embodiment] Next, a second embodiment of the present invention will be described with reference to Figures 5 and 6. In the second embodiment, unlike the first embodiment in which the retracted position is a position where the operation unit 6 located at the operating position is rotated 90 degrees relative to the tabletop 1, an example will be described in which the retracted position is a position where the operation unit 6 located at the operating position is rotated approximately 180 degrees relative to the tabletop 1. Note that the same components as those in the first embodiment will be assigned the same reference numerals, and their description will be omitted.

[0058] FIG. 6 is a schematic side view showing the operation unit 6, operation unit moving unit 7, and tabletop 1 as viewed from the X1 direction. The operation unit 6 shown in the upper diagram of FIG. 6 is located in the operation position. For ease of explanation, the engagement member 71 is shown by a dashed line in the upper diagram of FIG. 6. The operation unit 6 shown in the lower diagram of FIG. 6 is located in the retracted position.

[0059] As shown in FIG. 6 , the invalidation detection unit 80 is configured to detect the operation unit 6. The invalidation detection unit 80 is, for example, a push switch. In this embodiment, the invalidation detection unit 80 is provided on the inner surface 73c of the operation position maintaining unit 73. When the operation unit 6 is located at the operation position, the invalidation detection unit 80 detects that the operation unit 6 is at the operation position by being pressed by the guide unit 70. Furthermore, when the operation unit 6 located at the operation position is rotated and moved away from the operation position, the invalidation detection unit 80 does not detect that the operation unit 6 is at the operation position by releasing the pressure from the guide unit 70.

[0060] The invalidation control unit 81 is configured to cancel the invalidation of input operations related to X-ray photography to the operation unit 6 including the operation lever 61 based on the detection of the operation unit 6 by the invalidation detection unit 80, and to invalidate input operations related to X-ray photography to the operation unit 6 including the operation lever 61 based on the invalidation detection unit 80 not detecting that the operation unit 6 is in the operation position. Specifically, the invalidation control unit 81 cancels the invalidation of input operations related to X-ray photography to the operation unit 6 including the operation lever 61 based on the invalidation detection unit 80 detecting that the operation unit 6 is in the operation position because the operation unit 6 is located in the operation position. Furthermore, the invalidation control unit 81 invalidates input operations related to X-ray photography to the operation unit 6 including the operation lever 61 based on the invalidation detection unit 80 not detecting that the operation unit 6 is in the operation position because the operation unit 6 has moved from the operation position.

[0061] (Operating position and evacuation position) In this embodiment, the operation unit 6 is configured to move between the operation position and the retracted position by rotating approximately 180 degrees relative to the tabletop 1. The operation unit 6 rotates approximately 90 degrees in a direction in which the vertical component of the operation lever 61 decreases, and then rotates another approximately 90 degrees in the same rotation direction as the above rotation direction in a direction in which the vertical component of the operation lever 61 increases, thereby moving from the operation position to the retracted position.

[0062] As shown in the upper diagram of Fig. 6, the operating position is a position of the operating unit 6 where the operating panel 60 of the operating unit 6 faces upward and is arranged substantially horizontally. When the operating unit 6 is located at the operating position, the invalidation detection unit 80 is pressed by the guide unit 70 and therefore detects that the operating unit 6 is at the operating position. Therefore, the invalidation control unit 81 cancels the invalidation of input operations related to X-ray imaging to the operating unit 6, including the operating lever 61 located at the operating position.

[0063] When the operation unit 6 is located at the operation position, the operation position maintaining unit 73 maintains the operation unit 6 at the operation position.

[0064] As shown in the lower diagram of FIG. 6, the length by which the operation unit 6 protrudes from the side surface 10 of the tabletop 1 in the retracted position is relatively shorter than the length by which it protrudes in the operating position. The retracted position is below the position on the side surface 10 of the tabletop 1 where the operation unit 6 is provided in the operating position. The retracted position is a position of the operation unit 6 where the operation panel 60 of the operation unit 6 faces downward (in the Z2 direction) and is disposed approximately horizontally. In other words, the retracted position is a position where the operation unit 6 located in the operating position is rotated approximately 180 degrees with respect to the tabletop 1.

[0065] In the retracted position, the operation unit 6 is disposed below the tabletop 1 and the guide unit 70. That is, in the retracted position, the operation lever 61, the operation button 62, and the touch panel 63 are disposed below the tabletop 1 and the guide unit 70. In the retracted position, the operation lever 61 and the operation button 62 included in the first operation unit 6a and the third operation unit 6c protrude in the Z2 direction from the operation panel 60. In the retracted position, the display surface of the touch panel 63 included in the second operation unit 6b faces downward (in the Z2 direction). The operation unit 6 moves between the operation position and the retracted position by rotating approximately 180 degrees relative to the tabletop 1. This allows the operation unit 6 located in the retracted position to have a smaller amount of upward protrusion of the operation lever 61 protruding from the operation unit 6 compared to the operation unit 6 located in the operation position, thereby more effectively suppressing interference between the operation lever 61 and the surgeon during treatment.

[0066] Furthermore, when the operation unit 6 is located in the retracted position, the invalidation detection unit 80 does not detect that the operation unit 6 is in the operation position because it is not pressed by the guide unit 70. Therefore, the invalidation control unit 81 invalidates input operations related to X-ray imaging to the operation unit 6, including the operation lever 61 located in the retracted position. Therefore, the operation unit 6 located in the retracted position does not accept input operations by the operator to the operation lever 61, operation button 62, and touch panel 63 included in the operation unit 6.

[0067] When the operation unit 6 is located at the retracted position, the retracted position maintaining unit 74 maintains the operation unit 6 at the retracted position.

[0068] (Configuration of the operation unit movement part) The following describes the configuration of the operation unit moving unit 7. The operation unit moving unit 7 includes a guide unit 70, an engaging member 71, a rotational connection unit 72, an operation position maintaining unit 73, and a retracted position maintaining unit 74.

[0069] The pivotal connection part 72 is attached to the engagement member 71. In this embodiment, the pivotal connection part 72 has a hinge with one wing (not shown) attached to the bottom surface 71a of the engagement member 71 and a hinge with the other wing (not shown) attached to the side surface 60a on the top plate side (Y2 direction side) of the operation unit 6 located at the operation position. The operation unit 6 moves between the operation position and the retracted position by pivoting via the pivotal connection part 72.

[0070] As shown in FIGS. 5 and 6 , the operation position maintaining unit 73 is configured to maintain the operation unit 6 in the operation position. In this embodiment, the operation position maintaining unit 73 is configured to engage with the guide unit 70. The operation position maintaining unit 73 is, for example, a hook. The operation position maintaining unit 73 is provided on the side surface 60a on the top plate side (Y2 direction side) of the operation unit 6 positioned in the operation position. As shown in the upper diagram of FIG. 6 , the operation position maintaining unit 73 engages with the guide unit 70 to restrict the rotational movement of the operation unit 6 positioned in the operation position and maintain the operation unit 6 in the operation position. Furthermore, when the surgeon disengages the operation position maintaining unit 73 from the guide unit 70, the restriction on the rotational movement of the operation unit 6 positioned in the operation position is released. Note that, in this embodiment, the operation position maintaining unit 73 is not limited to a hook and may be any member that can engage with the guide unit 70.

[0071] As shown in FIG. 6, the retracted position maintaining unit 74 is configured to maintain the operation unit 6 in the retracted position. The retracted position maintaining unit 74 is configured to be detachable from the lower part of the tabletop 1. The retracted position maintaining unit 74 includes, for example, a magnet. The retracted position maintaining unit 74 is provided on the underside of the operation unit 6 positioned in the operation position. As shown in the lower diagram of FIG. 6, the retracted position maintaining unit 74 is attached to the lower part of the tabletop 1 by magnetic force, thereby restricting the rotational movement of the operation unit 6 positioned in the retracted position and maintaining the operation unit 6 in the retracted position. In addition, when the surgeon moves the retracted position maintaining unit 74 away from the lower part of the tabletop 1, the restriction on the rotational movement of the operation unit 6 positioned in the retracted position is released.

[0072] Note that if the lower part of the table top 1 corresponding to the retracted position maintaining unit 74 when the operation unit 6 is in the retracted position is not formed of a magnetic material, a magnetic material may be provided on the lower part of the table top 1 corresponding to the retracted position maintaining unit 74. Furthermore, the retracted position maintaining unit 74 is not limited to a magnet, and is not particularly limited as long as it is a member that can be maintained at the lower part of the table top 1. For example, the retracted position maintaining unit 74 may be formed of an engaging member that includes a protrusion that can engage with an engaging hole formed in the lower part of the table top 1.

[0073] (Movement between the operating position and the retracted position by rotating the operating part) Referring to FIG. 6, the movement of the operating unit 6 between the operating position and the retracted position due to rotation will be described.

[0074] 6, the operating position maintaining portion 73 restricts the rotational movement of the operating portion 6 located at the operating position by engaging with the guide portion 70. The operating portion 6 is maintained at the operating position.

[0075] Then, as shown in the lower diagram of Figure 6, the operator disengages the operating position maintaining unit 73 from the guide unit 70, thereby releasing the restriction on the rotational movement of the operating unit 6 by the operating position maintaining unit 73. As a result, the operating unit 6 rotates downward due to its own weight and is rotated by the operator, moving from the operating position to the retracted position. At the retracted position, the retracted position maintaining unit 74 is magnetically attracted to the bottom of the tabletop 1, thereby restricting the rotational movement of the operating unit 6 located at the retracted position. The operating unit 6 is maintained in the retracted position.

[0076] Then, when the surgeon moves the retracted position maintaining unit 74 away from the bottom of the tabletop 1, the restriction on rotational movement of the operation unit 6 located at the operation position by the retracted position maintaining unit 74 is released. Then, when the surgeon rotates the operation unit 6 located at the retracted position upward, it moves from the retracted position to the operation position, and the operation position maintaining unit 73 engages with the guide unit 70, so that the operation position maintaining unit 73 restricts rotational movement of the operation unit 6 located at the operation position. As a result, the operation unit 6 is maintained at the operation position as shown in the upper diagram of FIG. 6 .

[0077] The other configurations of the second embodiment are the same as those of the first embodiment.

[0078] (Effects of the second embodiment) In the second embodiment, the following effects can be obtained.

[0079] As described above, the second embodiment includes a retracted position maintaining unit 74 that maintains the operation unit 6 in the retracted position. This allows the operation unit 6 to be reliably maintained in the retracted position, thereby preventing the position of the operation unit 6 from becoming unstable due to the operation unit 6 not being maintained in the retracted position. This further reduces interference between the operator and the operation lever 61 of the operation unit 6 in the retracted position.

[0080] The other effects of the second embodiment are the same as those of the first embodiment.

[0081] [Third embodiment] Next, a third embodiment of the present invention will be described with reference to Fig. 7. In the third embodiment, unlike the first embodiment in which the first operating unit 6a, the second operating unit 6b, and the third operating unit 6c are rotated integrally with respect to the tabletop 1 and thereby moved integrally between the operating position and the retracted position, an example will be described in which the first operating unit 6a, the second operating unit 6b, and the third operating unit 6c are each configured to be independently rotatable with respect to the tabletop 1. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and their description will be omitted.

[0082] As shown in Fig. 7, in the X-ray imaging apparatus 200 according to the third embodiment, the first operation unit 6a, the second operation unit 6b, and the third operation unit 6c are each configured to be independently movable between an operation position and a retracted position in which the protruding lengths of the first operation unit 6a, the second operation unit 6b, and the third operation unit 6c from the side surface 10 of the tabletop 1 are relatively shorter than the protruding lengths in the operation positions. For convenience of explanation, Fig. 7 shows an example in which the first operation unit 6a is located in the retracted position and the second operation unit 6b and the third operation unit 6c are located in the operation positions. Note that the first operation unit 6a and the second operation unit 6b may be located in the retracted position and the third operation unit 6c may be located in the operation position, or the first operation unit 6a may be located in the operation position and the second operation unit 6b and the third operation unit 6c may be located in the retracted position.

[0083] In the third embodiment, an engagement member 71, a rotational connection portion 72, an operating position maintaining portion 73 (not shown), and an invalidation detection portion 80 (not shown) are provided for each of the first operating portion 6a, the second operating portion 6b, and the third operating portion 6c.

[0084] The other configurations of the third embodiment are the same as those of the first embodiment.

[0085] (Effects of the third embodiment) In the third embodiment, the following effects can be obtained.

[0086] In the third embodiment, as described above, the operation unit 6 includes a first operation unit 6a, a second operation unit 6b, and a third operation unit 6c arranged along the longitudinal direction of the tabletop 1. Each of the first operation unit 6a, the second operation unit 6b, and the third operation unit 6c is configured to be independently movable between an operation position and a retracted position in which the protruding length of the first operation unit 6a, the second operation unit 6b, and the third operation unit 6c from the side surface 10 of the tabletop 1 is relatively shorter than the protruding length in the operation position. This allows the first operation unit 6a, the second operation unit 6b, or the third operation unit 6c, which does not require input operation by the surgeon, to be individually selected and moved to the retracted position. This more effectively reduces interference between the operation lever 61 of the operation unit 6 that does not require input operation and the surgeon.

[0087] The other effects of the third embodiment are the same as those of the first embodiment.

[0088] [Variations] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims rather than the above description of the embodiments, and further includes all modifications (variations) within the meaning and scope of the claims.

[0089] For example, in the first and second embodiments, an example was described in which the operation unit 6 includes a first operation unit, a second operation unit, and a third operation unit, but the present invention is not limited to this. For example, the operation unit 6 may be configured to include only the first operation unit, or may be configured to include the first operation unit and the second operation unit, or may be configured to include four or more operation units. Furthermore, in the third embodiment, an example was described in which the operation unit 6 includes the first operation unit, the second operation unit, and the third operation unit, but the present invention is not limited to this. For example, the operation unit 6 may be configured to include the first operation unit and the second operation unit, or may be configured to include four or more operation units.

[0090] In the first to third embodiments, the operating unit is configured to be movable between an operating position and a retracted position by rotating relative to the tabletop. However, the present invention is not limited to this. For example, the tabletop may include a housing formed from the side surface toward the interior, capable of housing the guide unit and the operating unit. The guide unit may move in the Y1 direction from the side surface of the tabletop together with the operating unit housed in the housing inside the tabletop, to the outside of the tabletop, and move in the Y2 direction together with the operating unit into the housing inside the tabletop. In other words, the operating unit may be configured to be movable between the operating position where it is housed inside the tabletop together with the guide unit and then pulled out to the outside of the tabletop, and the retracted position where it is housed inside the tabletop together with the guide unit, thereby varying the length of protrusion of the operating unit from the side surface of the tabletop. In this case, the length of protrusion of the operating unit from the side surface of the tabletop in the retracted position is relatively smaller than the length of protrusion of the operating unit from the side surface of the tabletop in the operating position. In the above configuration, the X-ray imaging apparatus further includes a guide unit moving unit that moves the guide unit in the Y direction, and the operation unit is configured to be movable between an operation position and a retracted position in which the protruding length of the operation unit from the side surface of the tabletop is relatively smaller than the protruding length at the operation position by moving in the Y direction via the guide unit moving unit rather than rotating with respect to the tabletop. Note that the disabling unit may be configured to disable input operations related to X-ray imaging to the operation unit including the operation lever based on the operation unit moving to the retracted position, and to cancel the disabling of input operations related to X-ray imaging to the operation unit including the operation lever based on the operation unit moving to the operation position.

[0091] In the first to third embodiments, the operating unit is moved between the operating position and the retracted position by being manually rotated by the surgeon via the rotary connector, but the present invention is not limited to this. For example, the operating unit may be configured to be rotated by an electric motor to be moved between the operating position and the retracted position.

[0092] Furthermore, in the above-described first to third embodiments, the invalidation unit includes an invalidation detection unit and an invalidation control unit, and the invalidation detection unit detects the operation unit, and the invalidation control unit invalidates or cancels the invalidation of input operations related to X-ray imaging based on the detection of the operation unit by the invalidation detection unit. However, the present invention is not limited to this. For example, the invalidation unit may be configured to include an invalidation detection unit without including an invalidation control unit. As an example, when a signal terminal included in the invalidation detection unit and a signal terminal included in the operation unit are in contact with each other, a signal circuit is electrically connected, thereby canceling the invalidation of input operations related to X-ray imaging to the operation unit including the operation lever, and when the signal terminal included in the invalidation detection unit and the signal terminal included in the operation unit are separated from each other, the signal circuit is interrupted, thereby invalidating input operations related to X-ray imaging to the operation unit including the operation lever.

[0093] In addition, in the first to third embodiments, the invalidation detection unit is a push switch, but the present invention is not limited to this. For example, the invalidation detection unit is not limited to a contact-type push switch, and may be configured with a non-contact sensor or the like.

[0094] In the first embodiment, the operation position maintaining unit is a rod-shaped member that detachably connects the outer surface of the engagement member and the bottom surface of the operation unit, and the operation unit is configured to move between the operation position and the retracted position by rotating 90 degrees with respect to the top plate, and in the second embodiment, the operation position maintaining unit is a hook that is configured to engage with a guide portion and is configured to move between the operation position and the retracted position by rotating approximately 180 degrees with respect to the operation unit top plate. However, the present invention is not limited to this. For example, the operation position maintaining unit may be a rod-shaped member that detachably connects the outer surface of the engagement member and the bottom surface of the operation unit, and the operation unit may be configured to move between the operation position and the retracted position by rotating approximately 180 degrees with respect to the top plate, or the operation position maintaining unit may be a hook that is configured to engage with a guide portion and is configured to move between the operation position and the retracted position by rotating 90 degrees with respect to the operation unit top plate.

[0095] In the first embodiment, the operating position maintaining unit is a rod-shaped member that detachably connects the outer surface of the engagement member and the bottom surface of the operating unit, but the present invention is not limited to this. For example, the operating position maintaining unit may be a plate-shaped member that detachably connects the outer surface of the engagement member and the bottom surface of the operating unit. The configuration of the operating position maintaining unit is not particularly limited as long as it can maintain the operating unit in the operating position.

[0096] In the second embodiment, an example was shown in which a retracted position maintaining unit that maintains the operation unit in the retracted position was provided, but the present invention is not limited to this. For example, the retracted position maintaining unit does not have to be provided.

[0097] Furthermore, while the first to third embodiments each include a guide portion, the present invention is not limited to this. For example, the guide portion may not be provided. In this case, the engaging member may be attached to the side surface of the top plate.
