First embodiment

First, the schematic structure of the X-ray imaging apparatus 1 according to the first embodiment will be described with reference to FIG. Here, FIG. 1 shows a schematic structural diagram of the X-ray imaging apparatus 1 according to this embodiment.
In FIG. 1, an X-ray imaging apparatus generally indicated by reference numeral 1 is provided with a support column 50 that moves up and down in a telescopic manner on a carriage unit 30 that moves in a horizontal plane on a rail provided on a ceiling. This is an X-ray imaging apparatus called a ceiling suspension type in which an X-ray tube apparatus 101 is rotatably provided on a mounting block 70 which is provided so as to be able to turn in a part.

That is, the X-ray imaging apparatus 1 of this embodiment includes a carriage unit 30 that moves in a horizontal plane via an X-axis mechanism unit 10 and a Y-axis mechanism unit 20 provided on the ceiling, and a Z-axis from the carriage unit 30. A support column 50 suspended in a telescopic manner via a mechanism unit 40, a mounting block 70 attached to a lower part of the support column 50 via a turning mechanism unit 60 so as to be capable of turning, and a horizontal first rotating shaft 81 are provided. A head portion 100 rotatably attached to the attachment block 70 via a rotation mechanism portion 80, a lock mechanism portion (not shown) that fixes the movement of each of the plurality of mechanism portions, and a control device 5 that controls the lock mechanism. It is comprised including.

The X-axis mechanism unit 10 includes an X-axis frame body 11 attached to the ceiling surface, and the X-axis frame body 11 includes a pair of parallel X-axis rails 12. The Y-axis mechanism unit 20 includes a Y-axis frame body 21 that is movably held by a pair of X-axis rails 12 of the X-axis mechanism unit 10, and the Y-axis frame body 21 is a pair of parallel Y-axis rails. 22 is provided. The carriage unit 30 is movably held by the pair of Y-axis rails 22.

The carriage unit 30 is provided with a column 50 extending downward on the bottom surface. The support column 50 is formed to be extendable in the vertical direction (Z-axis direction) via a Z-axis mechanism unit 40 provided therein. The lower end portion of the support column 50 is provided with a turning mechanism portion 60 having the vertical direction (Z axis) as a rotation axis, and the attachment block 70 is attached to the turning block 60 via the turning mechanism portion 60 so as to be turnable.

The mounting block 70 is provided with a rotating mechanism 80 having a horizontal first rotating shaft 81 on the front surface thereof. The head unit 100 is attached to the rotation mechanism unit 80 so as to be rotatable about the first rotation shaft 81. The head portion 100 is provided with an X-ray tube device 101 provided with an X-ray movable diaphragm 102 having an X-ray irradiation axis Q orthogonal to the first rotation axis 81, that is, parallel to the Z axis. .

According to this structure, the horizontal X-ray irradiation axis Q and the X-ray irradiation axis Q orthogonal to the horizontal first rotation axis 81 can be rotated around the first rotation axis 81, and the X-ray tube apparatus 101 that emits X-rays can be X is pivoted in a horizontal plane around a Z axis parallel to the line irradiation axis Q, further moved up and down via the Z axis mechanism 40, and this pivot axis (Z axis) is attached to the ceiling surface. It can be moved in a horizontal plane formed by the shaft mechanism unit 10 and the Y-axis mechanism unit 20. Thereby, the X-ray irradiation axis Q can be directed to an arbitrary affected part of a patient who lies on the bed 4 disposed below or in the vicinity of the X-ray imaging apparatus 1. Each mechanism unit for moving these X-ray irradiation axes Q includes a lock mechanism unit (not shown) composed of an electromagnetic lock mechanism, and can be moved by releasing each lock mechanism.

The head unit 100 includes an X-ray tube apparatus 101 having an X-ray movable diaphragm 102, an operation panel 110 disposed on the front surface of the X-ray tube apparatus 101, and a circular base attached to the periphery of the operation panel 110. The handle 120 is configured to include an operation handle 130 that is rotatably attached to the base handle 120. The operation panel 110 includes a control device 5 and a storage device 6 that stores various types of information. Note that the control device 5 and the storage device 6 may be configured to include the inside of the carriage unit 30.

One of the major features of the X-ray imaging apparatus 1 according to this embodiment is that the X-ray imaging apparatus 1 is rotatably mounted via a second rotating shaft 131 that is arranged parallel to the first rotating shaft 81 and having a predetermined interval d. The operation handle 130 is provided.

That is, in the prior art, the base handle 120 employed in this embodiment is used to move the head unit 100. Since the base handle 120 is an annular handle formed in a circle around the first rotation shaft 81, the head portion 100 can be moved arbitrarily and X-ray irradiation can be performed by holding the annular base handle 120. The axis Q can be oriented in any direction. However, although the base handle 120 has the above advantages, there is a problem in that the position for holding the base handle 120 must be slightly changed when moving.

For example, when the head unit 100 is moved up and down, the base handle 120 is held up and down, and when the head unit 100 is moved left and right or turned, the left and right sides of the base handle 120 are held, and the X-ray irradiation axis Q is When rotating, the base handle 120 must be operated with both hands held like a car handle. Moreover, as long as it is frequently changed, it is necessary to devise an anti-slip mechanism when changing it. The operation of both hands is important.

Therefore, in this embodiment, the second rotation shaft 131 parallel to the first rotation shaft 81 is provided, and the operation handle 130 is rotatably provided on the second rotation shaft 131. According to this structure, since the operation handle 130 rotates about the second rotation shaft 131, it is possible to force an unreasonable posture on the hand (wrist) that holds the operation handle 130 regardless of the direction in which the operation handle 130 is pulled or pushed. Can be reduced. In addition, since the second rotary shaft 131 is provided at a predetermined distance d from the first rotary shaft 81, the X-ray irradiation axis Q can be obtained by rotating the second rotary shaft 131 around the first rotary shaft 81. Can be rotated. Of course, even in this rotation operation, the operation handle 130 rotates around the second rotation shaft 131, so that it is not necessary to change the gripping posture of the operation handle 130 during the rotation operation.

Another important feature of the X-ray imaging apparatus 1 according to this embodiment is that the operation handle 130 is provided with a lock release switch 132 for releasing the locked state of the plurality of lock mechanisms.

That is, in the prior art, the lock release switches 132 are provided on both sides of the front surface of the operation panel 110 so that the circular base handle 120 is positioned in the vicinity thereof. Therefore, in this prior art, the posture is such that the necessary unlocking switch 132 is operated and moved while holding both sides of the base handle 120 with both hands.

In contrast, in this embodiment, the lock release switch 132 is provided on the operation handle 130 that rotates about the second rotation shaft 131. According to this structure, the unlocking switch 132 can be operated with one hand while taking an easy holding posture, or the unlocking switch 132 can be operated with another hand while taking an easy holding posture with one hand. . In addition, since the second rotary shaft 131 is provided on the ring-shaped grip portion 121 of the base handle 120, an easy and reliable operation can be selected while using the base handle 120 and the operation handle 130 properly.

Thus, according to this embodiment, regardless of the physique of the operator, the operation handle 130 can be reached and the heavy tube (head unit 100) can be moved up and down and left and right freely even with a small force and an easy posture. The ceiling-suspended X-ray imaging apparatus 1 that can be rotated and can be fixed at a desired position by one-handed operation is realized.

Hereinafter, the X-ray imaging apparatus 1 according to this embodiment will be described in detail with reference to FIGS.

steps

201, 203, 205, 207, and 209, whether the unlock switch 132 assigned to the X-axis mechanism unit 10 has been operated, whether the unlock switch 132 assigned to the Y-axis mechanism unit 20 has been operated, Monitor whether the unlocking switch 132 assigned to the mechanism unit 40 is operated, whether the unlocking switch 132 assigned to the turning mechanism unit 60 is operated, or whether the unlocking switch 132 assigned to the rotation mechanism unit 80 is operated. Yes. When these lock release switches 132 are operated, the lock state of the lock mechanism corresponding to the operated lock release switch 132 is released (step 213). Then, the control device 5 monitors whether or not the operation of the lock release switch 132 has been released (step 215), and if released, the lock mechanism in the unlocked state is again set to the locked state (step 221). The process proceeds to step 201.

On the other hand, the control device 5 also monitors whether or not the free lock release switch 133 has been operated (step 211). When the free lock release switch 133 is operated, the control device 5 releases the lock state of all the lock mechanism units (step 217). Then, the control device 5 monitors whether or not the operation of the free lock release switch 133 is released (step 219), and if released, all the lock mechanism units are again locked (step 221). The process proceeds to step 201.

Next, the external structure of the head unit 100 will be further described with reference to FIG. Here, FIG. 3 is an external view of the head portion, where FIG. 3 (a) is a front view and FIG. 3 (b) is a side view.
As shown in the drawing, the head unit 100 is rotatably attached via a rotation mechanism unit 80 attached to the front surface of the attachment block 70. The rotation mechanism unit 80 is provided with a horizontal first rotation shaft 81, and the rear portion of the X-ray tube apparatus 101 is attached to the first rotation shaft 81. On the other hand, a thin operation panel 110 is attached to the front surface of the X-ray tube apparatus 101 in the depth direction, and a ring-shaped base handle 120 is attached via a plurality of support arms 122 so as to surround the operation panel 110. . Further, an X-ray movable diaphragm 102 is provided on the peripheral side of the X-ray tube apparatus 101 so that the X-ray irradiation axis Q is directed in a direction orthogonal to the first rotation shaft 81.

The operation panel 110 is provided with a control board (not shown) provided with the control device 5 and the storage device 6 therein, and various operation screens are displayed on the front surface by the control of the control device 5, and input by touch operation is performed. A display device 111 with a touch panel that can be operated and an aperture lamp switch 112 are provided. An aperture operation switch 103 is provided on the front surface of the X-ray movable aperture 102.

Further, in this embodiment, an operation handle 130 is provided that is rotatably attached to the grip portion 121 of the base handle 120 at a position in front of the distal end portion of the X-ray movable diaphragm 102 via the second rotation shaft 131. . Based on this positional relationship, the operator can recognize that the mounting position of the operation handle 130 is the tip of the X-ray movable diaphragm 102. Since the second rotation shaft 131 is provided with a predetermined distance d from the first rotation shaft 81 parallel to the second rotation shaft 131, the distal end portion of the movable diaphragm 102 is rotated with the predetermined distance d as a rotation radius. be able to.

In this embodiment, an operation handle 130 that can be held / operated with one hand, whether right-handed or left-handed, is employed. This will be further described with reference to FIGS. Here, FIG. 4 is an external view of the operation handle, where (a) is a front view, (b) is a bottom view, (c) is a rear view, (d) is a top view, and (e) is a view. Is a right side view, and (f) is a central longitudinal sectional view. FIGS. 5A and 5B are operation explanatory diagrams of the operation handle, in which FIG. 5A is an explanatory diagram showing a gripping posture with one hand, and FIGS. 5B and 5C are explanatory diagrams of a gripping operation. 6A and 6B are diagrams for explaining the operation of the operation handle. FIG. 6A is a rear view, FIG. 6B is a diagram showing the operation of one hand viewed from the front, and FIG. 6C is the operation of both hands viewed from the front. FIG.

As shown in FIG. 4, the operation handle 130 according to this embodiment has a flat external shape having a height dimension larger than the depth dimension and a width dimension larger than the height dimension. And the modeling at the center of the front is formed in a mountain shape with the upper part 135 as the top. That is, the lower part of the apex 135 projecting forward is a wide inclined surface 136 having a height, and the upper part is formed by an inclined surface 137 having a slightly lower height. On both sides of the chevron shape formed by the two inclined surfaces 136 and 137 (both sides in the left and right direction in FIG. 5A), a left and right symmetrical switch arrangement surface 138 is formed in which the apex 135 gently spreads in the shape of the hem on both sides. Is done. And on this symmetrical switch arrangement surface 138, the lock release switches 132 are arranged in a slightly shifted arrangement.

The rear side of the operation handle 130 is formed in a concave shape leaving an edge 139 around the periphery, as shown in FIG. 5C, and the second rotary shaft 131 is located at a position opposite to the center position of the wide inclined surface 136 on the front surface. The mounting portion 140 is provided, and a free lock release switch 133 is provided adjacent to the mounting portion 140 above.

As shown in FIG. 5 (a), the operation handle having such a shape presses the palm against the wide inclined surface 136 and wraps the back side from the narrow inclined surface 137 with fingers other than the thumb 139. The operation handle 130 can be grasped with one hand. With this holding posture, a force for pulling up or pushing the operation handle 130 upward can be transmitted from the palm of the hand via the wide inclined surface 136. On the other hand, the force to be pulled down can be transmitted by this force because it is held by being hooked with a finger other than the thumb.
The one hand holding the two

inclined surfaces

136 and 137 can reduce the force of shifting (sliding) to both sides due to the presence of the switch arrangement surface 138 spreading in the shape of the hem on both sides (left and right). .

In addition, as shown in FIG. 5B, when the two

inclined surfaces

136 and 137 are held with one hand and are to be moved left and right, the operation handle 130 is fixed to the base handle 120. However, in this embodiment, the operation handle 130 rotates with respect to the base handle 120 as shown in FIG. 5C, so that the arm can be used to move left and right. The problem that the wrist is burdened can be reduced.

Further, as shown in FIG. 6A, in this embodiment, since the free lock release switch 133 is provided on the back side, the free lock release switch 133 can be operated with a finger other than the thumb. Further, in this embodiment, as shown in FIG. 6B, since the lock release switches 132 other than the free lock release switch 133 are equally arranged on the left and right switch arrangement surfaces 138, these locks are locked. The release switch 132 can be operated by a thumb operation.

Further, in this embodiment, as shown in FIG. 6C, the left and right switch arrangement surfaces 138 can be operated even in a posture in which both hands are held. In this case, the switch placement surface 138 is pressed with the thumb, or the lock release switch 132 is operated, and the other finger is held using the edge 139, or the free lock release switch 133 is operated with the index finger. What should I do?
In this embodiment, a pair of lock release switches 132 are provided on the switch arrangement surfaces 138 on both sides, but they may be arranged so as to be biased to one side.

Next, a method for setting the position of the X-ray irradiation axis Q of the X-ray imaging apparatus 1 according to this embodiment will be described with reference to FIGS. FIG. 7 is an operation explanatory diagram of the X-ray imaging apparatus. According to this embodiment, the head unit 100 cannot be moved unless the lock release switch 132 is operated. However, the operation handle 130 can be freely rotated via the second rotation shaft 131.

FIGS. 7A and 7B illustrate the case where the head unit 100 is moved up and down. (A) In the figure, the X-ray irradiation axis Q is directed downward. From this state, if the lock release switch 132 for unlocking the Z-axis mechanism unit 40 is operated while grasping the operation handle 130 with a good hand, the head unit 100 can be moved up and down as it is. When the operation handle 130 is in a low position during the movement in the vertical direction, as shown in FIG. 5 (b), if the operation handle 130 is inverted 180 degrees, it is possible to take an easy posture to push down. .

Further, in the case of moving in the left-right direction from the state of (a), if the lock release switch 132 for releasing the lock of the X-axis mechanism unit 10 is operated, the head unit 100 is moved in the left-right direction as it is. Can do. In this case, as shown in (c), the operation handle 130 can be rotated, so that the operation handle 130 can be pulled in the left-right direction.

Further, in the case of rotating the X-ray irradiation axis Q from the state of (a), the head unit 100 can be rotated by operating the lock release switch 132 for unlocking the rotation mechanism unit 80. In this case, as shown in FIG. 6D, when the operation handle 130 is moved along the arrow in the figure, the operation handle 130 is freely rotated with respect to the base handle 120, and the operation handle 130 is kept at an angle that is easy for the operator to hold. Can be rotated easily.

Further, when it is desired to move the head unit 100 in the front-rear direction from the state shown in (a), if the lock release switch 132 for unlocking the Y-axis mechanism unit 20 is operated as shown in FIG. The head unit 100 can be moved in the forward / backward direction.
