In the following, a mobile X-ray diagnosis apparatus according to the present application will be described taking a mobile X-ray diagnosis apparatus in which a support and an arm are used as a support mechanism for supporting an X-ray tube as an example.

(First embodiment)
First, an example of the overall configuration of the mobile X-ray diagnostic apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of the overall configuration of a mobile X-ray diagnostic apparatus 1 according to the first embodiment. 1A shows a state when the X-ray tube is stored, and FIG. 1B shows a state when an X-ray image is taken. As shown in FIG. 1A, the mobile X-ray diagnostic apparatus 1 includes a column 2, an arm 3, an X-ray tube 4, an X-ray movable diaphragm 5, a front wheel 6, a rear wheel 7, An apparatus main body 8 and an operation handle 9 are provided.

  As shown in FIG. 1A, the support column 2 is disposed on the front side (front wheel 6 side) of the mobile X-ray diagnostic apparatus 1, and supports the arm 3 by connecting one end of the arm 3. One end of the arm 3 is connected to the support column 2, and an X-ray tube 4 and an X-ray movable diaphragm 5 are disposed at the other end. Here, the arm 3 is connected by the support column 2 so as to slide freely up and down. For example, a rail is installed on the support column 2, and the arm 3 slides up and down by moving on the rail with one end connected to the rail. Further, the arm 3 expands and contracts in a direction perpendicular to the long axis of the support column 2. That is, the arm 3 is retracted when the X-ray tube 4 is retracted and retracted so that the X-ray tube 4 does not protrude, and is expanded so that the X-ray tube 4 reaches farther when capturing the X-ray image. .

  The X-ray tube 4 is connected to a high voltage generator (not shown) included in the apparatus main body 8 and generates X-rays using a high voltage supplied from the high voltage generator. The X-ray movable diaphragm 5 has a mechanism for adjusting an irradiation field of X-rays generated by the X-ray tube 4. Specifically, the X-ray movable diaphragm 5 has two pairs of movable restriction blades, and the X-ray irradiation field is adjusted by opening and closing the movable restriction blades in each pair. That is, the movable restricting blade 5 is opened and closed so that the X-ray emitted in a conical shape by the X-ray tube 4 is irradiated to a predetermined irradiation field.

  The front wheel 6 is a turnable wheel, for example, a pair of casters. The rear wheel 7 is a drive wheel to which a motor or the like (not shown) is connected, and is driven according to an operation by an operator. For example, the rear wheel 7 is driven by a motor when a predetermined pressure is detected by a pressure sensor provided on an operation handle 9 described later, or a drive button disposed near the operation handle 9 is pressed. And driven by the power of the motor.

  The apparatus main body 8 includes a control unit that controls each unit of the mobile X-ray diagnostic apparatus 1, a storage unit that stores various data, a battery that stores electric power supplied from the outside, an operation unit that receives various operations, and various types. A display unit for displaying the information. Then, the apparatus main body 8 controls various processes related to movement of the mobile X-ray diagnostic apparatus 1 and various processes related to imaging of X-ray images. For example, the apparatus main body 8 controls the high voltage generation unit according to the operator's instruction transferred from the operation unit arranged on the upper surface of the apparatus main body 8, and adjusts the voltage supplied to the X-ray tube 4 to thereby The X-ray dose and ON / OFF to be controlled are controlled. Further, for example, the apparatus main body 8 controls the X-ray movable diaphragm 5 in accordance with an operator's instruction, and adjusts the opening degree of the movable restricting blade of the X-ray movable diaphragm 5 so as to irradiate the patient with X. Control the field of radiation.

  The apparatus main body 8 controls image data generation processing, image processing, analysis processing, and the like according to an instruction from the operator. Further, the apparatus main body 8 controls to display a GUI for receiving an operator's instruction, an image stored in the storage unit, and the like on the display of the display unit. Further, the apparatus body 8 drives a built-in motor in accordance with the pressure detected by the pressure sensor provided on the operation handle 9 or the operation received by the push button, and the rear wheel 7 is driven by the power of the motor. Drive.

  The operation handle 9 is a handle that is operated when the operator moves the mobile X-ray diagnostic apparatus 1. Here, the operation handle 9 according to the first embodiment is configured to make it easy to ensure the visibility of the operator when moving. Hereinafter, an example of the flow of X-ray image capturing using the mobile X-ray diagnostic apparatus 1 will be described. For example, the mobile X-ray diagnostic apparatus 1 is placed in a hallway or the like on each floor of a hospital during standby, and is charged according to the storage capacity of the battery. In use, the mobile X-ray diagnostic apparatus 1 is unlocked with a dedicated key or the like and moved to a hospital room or the like by the operator.

  When the operator moves to the hospital room, the operator turns the column 2 around the longitudinal direction as shown in FIG. 1B to move the X-ray tube 4 and the X-ray movable diaphragm 5 to the front of the apparatus main body 9. Turn to. Then, the operator extends the arm 3 and arranges the X-ray tube 4 at a position where X-rays are irradiated to the imaging region of the patient. Here, the operator uses a switch, a knob, or the like provided in the X-ray movable diaphragm 5 to adjust the imaging region to enter the irradiation field. Then, an image recording medium such as an FPD (Flat Panel Detector) or a cassette is set between the imaging region of the patient and the bed, and an X-ray image is taken.

  As described above, the mobile X-ray diagnostic apparatus 1 is moved to a hospital room where a patient is present during use, and an X-ray image is taken by adjusting the position and irradiation field of the X-ray tube 4 with respect to the imaging region. However, in the case of a conventional mobile X-ray diagnostic apparatus, the operator's field of view may be reduced during movement. FIG. 2 is a diagram illustrating an example of an operation handle of the mobile X-ray diagnostic apparatus according to the related art. For example, in the mobile X-ray diagnostic apparatus according to the related art, for example, as shown in FIG. 2, an operation handle 20 is provided on the rear side (rear wheel side) of the mobile X-ray diagnostic apparatus, or the front The operation handle 21 is provided on the side (front wheel side) support column.

  In the conventional mobile X-ray diagnostic apparatus provided with such an operation handle 20 or 21, the operator holds the operation handle 20 or 21, pushes or pulls it. The mobile X-ray diagnostic apparatus is moved. For example, when operating the operation handle 20 to run the mobile X-ray diagnostic apparatus, the operator faces the mobile X-ray diagnosis apparatus side from the operation handle 20 side (turns to the left in FIG. 2). ) Hold the operating handle 20 and push or pull it. For example, when operating the operation handle 21 to drive the mobile X-ray diagnostic apparatus, the operator faces the mobile X-ray diagnosis apparatus side from the operation handle 21 side (right direction in FIG. 2). Hold the operation handle 21 and push or pull it.

  As described above, in the conventional mobile X-ray diagnostic apparatus, the operator looks forward through the mobile X-ray diagnostic apparatus and looks backward while turning around, so that the operator at the time of movement Visibility may be reduced. 3A to 3B are diagrams illustrating an example of a situation when the mobile X-ray diagnostic apparatus according to the related art moves. For example, when the mobile X-ray diagnostic apparatus travels forward by operating the operation handle of the mobile X-ray diagnostic apparatus according to the related art, the mobile X-ray diagnostic apparatus operates as shown in FIG. 3A. When the operator's front is blocked, the operator's field of view decreases, and for example, it may be delayed to notice the presence of a child squatting forward.

  Further, for example, when the mobile X-ray diagnostic apparatus is moved forward by operating the operation handle of the mobile X-ray diagnostic apparatus according to the prior art, as shown in FIG. X-ray diagnostic equipment is more advanced, it is difficult to notice the situation at the corner of the corner, etc., and it is difficult to take measures according to the situation in advance for various situations such as the patient coming to here It may become.

  Further, for example, in the mobile X-ray diagnostic apparatus according to the related art, when the mobile X-ray diagnostic apparatus travels backward by operating the operation handle when leaving the room, for example, FIG. 3C shows In this way, the operator will move backwards, and the visibility will be reduced, so it will be difficult to notice the situation in the back, and will respond immediately to various situations such as a nurse heading here in the hallway May be difficult.

  Therefore, in the mobile X-ray diagnostic apparatus 1 according to the first embodiment, the operation handle 9 is configured so as to easily ensure the operator's field of view when moving. Specifically, the operation handle 9 according to the first embodiment is operated when the apparatus main body 8 travels, and is substantially parallel to the traveling direction on both the left and right sides of the surface orthogonal to the traveling direction in the apparatus main body 8. Each is arranged so that the direction is the major axis direction. 4A and 4B are diagrams illustrating an example of the operation handle 9 according to the first embodiment.

  For example, as shown in FIG. 4A, the operation handle 9 is formed so as to protrude from both the left and right sides of the surface orthogonal to the traveling direction of the apparatus body 8 in a direction substantially parallel to the traveling direction. That is, as shown in FIG. 4A, the operation handle 9 is formed in a rod shape so as to protrude from both sides of the rear side (rear wheel 7 side) surface of the apparatus main body 8. Here, the operation handle 9 is formed so that an operator who travels the apparatus main body 8 can operate the apparatus main body 8 in a back-facing state. That is, the operation handle 9 is formed with such a length that allows the operator to pull (operate) the device main body 8 with its back turned. Hereinafter, pulling (operating) the mobile X-ray diagnostic apparatus 1 by the operator may be referred to as traction.

  Furthermore, the operation handle 9 according to the first embodiment is formed so as to protrude in a direction substantially parallel to the traveling direction from both the left and right sides of the front and rear surfaces of the apparatus main body 8 in the traveling direction. For example, as shown in FIG. 4B, the operation handle 9 is formed in a rod shape so as to protrude from both sides of the front side (front wheel 6 side) surface of the apparatus body 8. The operation handle 9 on the front side shown in FIG. 4B is also formed with such a length that allows the operator to pull the device main body 8 with his back turned.

  Here, an example of the configuration of the operation handle 9 according to the first embodiment will be described with reference to FIGS. 5A to 5C. 5A to 5C are diagrams illustrating an example of the configuration of the operation handle 9 according to the first embodiment. For example, as shown in FIG. 5A, the operation handle 9 includes a handle storage portion 9a, a front handle portion 9b, and a rear handle portion 9c, and is formed to be extendable and contractible in the long axis direction. That is, as shown in FIG. 5A, the operation handle 9 according to the first embodiment is pulled out by extending the front handle portion 9b or the rear handle portion 9c from the handle storage portion 9a when the device main body 8 is traveling. When the operation handle 9 is stopped, the front handle portion 9b and the rear handle portion 9c are contracted and stored in the handle storage portion 9a.

  In such a case, for example, the front handle portion 9b and the rear handle portion 9c have a telescopic structure as shown in FIGS. 5B and 5C, respectively. For example, since the front handle portion 9b is provided with the support column 2 and the like on the front side, as shown in FIG. 5B, the front handle portion 9b is configured to be extended and contracted stepwise by a double extension structure. The That is, as shown in FIG. 5B, the front handle portion 9b is stored in the handle storage portion 9a as a hollow similar cylinder, and the front handle portion 9b on the inner side and the outer side of both ends of the handle storage portion 9a. A barb is provided on each of the outer sides of the one end, and the front handle portion 9b is configured not to come off during expansion and contraction.

  Similarly, the front handle portion 9b on the inner side is provided with a barb on the outer side of one end. And it is comprised so that the inner side front handle part 9b may not come out at the time of expansion | extension and shrinkage | contraction by providing a return | turnback inside the both ends of the outer side front handle part 9b. And the front handle | steering-wheel part 9b inside is provided with the holding part hold | gripped by the operator at the edge part opposite to the edge part provided with the return | turnback.

  Further, for example, as shown in FIG. 5C, the rear handle portion 9c is stored inside the front handle portion 9b as a column similar to the front handle portion 9b. The rear handle portion 9c is configured such that a barb is provided on the outer side of one end and a barb is provided on the inner side of both ends of the front handle unit 9b on the outer side, so that the rear handle unit 9c does not come out during expansion and contraction. The rear handle portion 9c is provided with a gripping portion that is gripped by an operator at an end opposite to the end provided with the barb. 5A to 5C, one of the front handle portion 9b and the rear handle portion 9c is extended.

  As described above, the operation handle 9 according to the first embodiment is formed so that the front handle portion 9b and the rear handle portion 9c protrude from both sides of the apparatus body 8 on the front side and the rear side. The operator stands with his back to the device main body 8 and pulls the grip portions of the front handle portion 9b or the rear handle portion 9c protruding from the side surfaces on both sides of the device main body 8 with his / her left and right hands, respectively. As a result, the mobile X-ray diagnostic apparatus 1 is caused to travel.

  Here, the gripping portions of the front handle portion 9b and the rear handle portion 9c may have various structures in order to improve the operability for the operator. 6A to 6C are diagrams illustrating an example of a grip portion of the operation handle 9 according to the first embodiment. 6A to 6C, the front handle portion 9b will be described as an example, but the rear handle portion 9c may have the same structure as that of FIGS. 6A to 6C.

  For example, as shown in FIG. 6A, the grip portion of the operation handle 9 is disposed on the front end side of the front handle portion 9b, and is prevented from slipping by rubber 11 or the like. Further, for example, as shown in FIG. 6B, the grip portion of the operation handle 9 is disposed on the front end side of the front handle portion 9b, and a stopper 12 is formed at the front end of the front handle portion 9b. Further, for example, as shown in FIG. 6C, the grip portion of the operation handle 9 is disposed on the front end side of the front handle portion 9b and is formed so as to gradually become thicker toward the front end.

  As described above, the operation handle 9 according to the first embodiment is formed to be parallel to the traveling direction. Accordingly, the grip portions of the front handle portion 9b and the rear handle portion 9c in the operation handle 9 are also parallel to the traveling direction, and may slip when the operator grips and pulls. Therefore, as shown in FIGS. 6A to 6C, the gripping portion of the operation handle 9 is prevented from slipping due to the frictional force between the operator's hand and the gripping portion, or is gripped by the operator's hand being pulled. It has a structure for preventing it from coming off from the part. Note that the examples shown in FIGS. 6A to 6C are merely examples, and the grip portion of the operation handle 9 can have various other structures. Each of FIGS. 6A to 6C may be applied, or may be a combination of the structure of FIG. 6A and the structure of FIG. 6C.

  Here, the gripping portion of the operation handle 9 according to the first embodiment may be formed so as to be parallel to the traveling direction of the apparatus main body 8 as shown in FIGS. 6A to 6C. Alternatively, it may be formed so as to be perpendicular to the traveling direction of the apparatus body 8. Hereinafter, an example in which the grip portion of the operation handle 9 is in a direction orthogonal to the traveling direction of the apparatus main body 8 will be described with reference to FIGS. 6D to 6F. 6D to 6F are diagrams illustrating an example of a grip portion of the operation handle 9 according to the first embodiment. 6D to 6F, the front handle portion 9b will be described as an example, but the rear handle portion 9c may have the same structure as that of FIGS. 6D to 6F.

  For example, as shown in the dotted circle in FIG. 6D, the front handle portion 9b is bent inward at the end opposite to the apparatus main body 8 side to form a grip portion. That is, the operator can enter the space between the front handle 9b shown in FIG. 6D, grip the grip portion, and drive the mobile X-ray diagnostic apparatus 1 with a pressing force. Here, as shown in FIG. 6D, the grip portion of the front handle portion 9b is formed with a width that can be gripped, and an operator can freely enter and leave between the front handle 9b through a gap between the grip portions. Formed as follows.

  Moreover, as a grip part formed so that it may become a direction orthogonal to the advancing direction of the apparatus main body 8, for example, as shown to FIG. 6E, the front handle | steering-wheel part 9b is equipped with a foldable joint mechanism, The part folded inside the handle part 9b may be used as a grip part. That is, the front handle portion 9b is a joint mechanism in which the grip portion is bent in the direction of the arrow 31, as shown in FIG. 6E, or a joint mechanism in which the grip portion is bent in the direction of the arrow 32, or the arrows 31 and 32 A joint mechanism that bends in both directions and a lock mechanism that fixes the grip portion in a bent state are provided.

  In addition, as a grip portion formed so as to be orthogonal to the traveling direction of the apparatus main body 8, for example, as shown in FIG. 6F, the front handle portion 9b is provided with a rotation mechanism capable of rotating the shaft, It may be formed so as to rotate about the longitudinal direction as an axis. That is, as shown in FIG. 6F, the front handle portion 9b is formed with a grip portion in which an end opposite to the apparatus main body 8 side is bent inward, and an arrow with the longitudinal direction of the front handle portion 9b as a rotation axis. A rotation mechanism for rotating in both directions is provided.

  As a result, when the operator runs the mobile X-ray diagnostic apparatus 1, the operator bends the gripping part in the direction of the arrow 31 or the arrow 32 so as to create a gap between the front handle part 9b, and the front handle The gripping portion is bent in the direction of the arrow 31 or the arrow 32 so that the gripping portion is in a direction perpendicular to the traveling direction, entering between the portions 9b. Thereafter, the operator fixes the grip portion in a direction orthogonal to the traveling direction by the lock mechanism, thereby gripping the grip portion and causing the mobile X-ray diagnostic apparatus 1 to travel.

  As described above, the operation handle 9 according to the first embodiment can include a gripping portion in a direction parallel to or orthogonal to the traveling direction of the apparatus main body 8. Here, in the mobile X-ray diagnostic apparatus 1, as described above, a predetermined pressure is detected by a pressure sensor provided on the operation handle 9, or a drive button disposed near the operation handle 9 is pressed. By doing so, the motor is driven and driven by the power from the motor. That is, the mobile X-ray diagnostic apparatus 1 has an assist function by the rear wheel 7 so that the mobile X-ray diagnostic apparatus 1 can easily move.

  Here, the mobile X-ray diagnostic apparatus 1 is configured so that the assist function works in the direction in which the operator is moving so that the apparatus does not move against the intention of the operator. A button is provided. 7A and 7B are views for explaining control by a pressure sensor provided in the operation handle 9 according to the first embodiment. 7A and 7B, the front handle portion 9b will be described as an example, but the rear handle portion 9c may have the same configuration as that in FIG. 7A or 7B. Moreover, FIG. 7A shows the case where a pressure sensor is provided in the holding part shown in FIG. 6A. FIG. 7B shows a case where a pressure sensor is provided in the grip portion shown in FIG. 6D.

  For example, in the gripping portion shown in FIG. 6A (the gripping portion formed in a direction parallel to the traveling direction), the pressure in the direction of the arrow 33 shown in FIG. 7A and the (B) in FIG. The pressure sensor which detects the pressure of the direction of the arrow 34 shown in FIG. That is, the operator stands with the back facing the apparatus body 8 on the front side (for example, the front wheel 6 side in FIG. 5A), and holds the grip portion shown in FIG. 7A (A) and pushes it forward. In this case, a pressure sensor for detecting the pressure in the direction of the arrow 33 applied when the apparatus is moved to the front side is provided. Further, a pressure sensor for detecting the pressure in the direction of the arrow 34 applied when the operator stands on the front side and grips the gripping portion shown in FIG. 7A (B) to move the apparatus to the rear side. Provided.

  And the apparatus main body 8 drives the built-in motor according to the pressure detected by the pressure sensor with which the holding part was equipped, and drives the rear-wheel 7 with the motive power of a motor. That is, when the pressure sensor detects the pressure in the direction of the arrow 33, the apparatus main body 8 drives the motor so as to move the mobile X-ray diagnostic apparatus 1 toward the front side. On the other hand, when the pressure sensor detects the pressure in the direction of the arrow 34, the apparatus main body 8 drives the motor so as to move the mobile X-ray diagnostic apparatus 1 toward the rear side.

  When the operator stands on the rear side (for example, the rear wheel 7 side in FIG. 5A) and moves the mobile X-ray diagnostic apparatus 1, the direction of pressure detected by the grip portion of the rear handle portion 9c Then, the traveling direction of the apparatus main body 8 is reversed. That is, when the operator stands with the back facing the apparatus main body 8 on the rear side, and grips the grip part and pushes it forward, the pressure in the same direction as the arrow 33 is detected with respect to the grip part. However, the apparatus main body 8 drives the motor so as to move the mobile X-ray diagnostic apparatus 1 toward the rear side. On the other hand, when the operator stands on the rear side and grips the grip portion of the rear handle portion 9c and applies pressure in the same direction as the arrow 34, the apparatus body 8 moves the mobile X-ray diagnostic apparatus 1 The motor is driven so as to move toward the front side. The driving of these motors is controlled according to the handle portion where the pressure is detected (whether detected by the front handle portion 9b or the rear handle portion 9c).

  Similarly, in the gripping portion shown in FIG. 6D (the gripping portion formed in a direction orthogonal to the traveling direction), as shown in FIG. 7B, the pressure in the direction of the arrow 35 and the pressure in the direction of the arrow 36 are applied. A pressure sensor for sensing is provided. When the pressure sensor detects the pressure in the direction of the arrow 35 (for example, when the operator grips and presses the grip portion with the back facing the device body 8 on the front side), the device The main body 8 drives a motor so as to move the mobile X-ray diagnostic apparatus 1 toward the front side. On the other hand, when the pressure sensor detects the pressure in the direction of the arrow 36 (for example, when the operator stands on the front side and applies pressure to the gripping part from the direction of the arrow 36), the apparatus main body 8 is movable. The motor is driven so as to move the X-ray diagnostic apparatus 1 toward the rear side. 7B, when the operator stands on the rear side and moves the mobile X-ray diagnostic apparatus 1, the direction of the pressure detected by the grip portion of the rear handle portion 9c The traveling direction of the apparatus body 8 is reversed.

  Here, the apparatus main body 8 is controlled so that the rear wheel 7 is braked when pressure detection by the pressure sensor provided in the grip portion is lost in order not to move the apparatus against the intention of the operator. To do. That is, the apparatus main body 8 performs control so that the motor is driven to assist only when the operator tries to move the apparatus. In the above-described example, the case where the operator's operation is detected by the pressure sensor has been described. However, a push button may be used. In such a case, for example, when a pressure sensor is provided in the gripping portion, a push button is disposed near the gripping portion of the operation handle 9, the pressure sensor detects pressure, and the push button is pressed, The apparatus main body 8 is controlled to drive the rear wheel 7. Alternatively, when a push button is provided in the vicinity of the handle storage portion 9a of the apparatus main body 8, the grip portion is gripped in a state where the front handle portion 9b or the rear handle portion 9c is stored, and the push button is pressed, The apparatus main body 8 is controlled to drive the rear wheel 7. In such a case, even when the front handle portion 9b and the rear handle portion 9c are stored in the handle storage portion 9a, the gripping portion is projected outward. When the push button is arranged, control may be performed so that the brake is applied when the push button is stopped.

  As described above, the operation handle 9 according to the first embodiment has the front handle portion 9b, the rear handle portion 9c, and the handle storage portion 9a so as to be extendable in the longitudinal direction, and the front handle portion 9b. The rear handle portion 9c is configured to be stored in the handle storage portion 9a. Here, the operation handle 9 according to the first embodiment has not only a configuration in which the front handle portion 9b and the rear handle portion 9c are stored inside the apparatus main body 8, as shown in FIG. 4A, FIG. 5A, and the like. For example, it is possible to adopt a configuration in which the side surface of the apparatus main body 8 is slid.

  FIG. 8 is a view showing a modification of the operation handle 9 according to the first embodiment.
