Description

Technical Field

[0001] The embodiments disclosed in this specification and the drawings relate to a medical support device, a medical bed device, and an X-ray diagnosis device. Background Art

[0002] Conventionally, in X-ray imaging, when a subject cannot maintain a correct position and posture, the subject is supported by the hands of a treating radiologist (hereinafter referred to as a radiologist) or an auxiliary tool.

[0003] However, when the technician supports the subject with his / her hands, the technician's radiation exposure may increase. In addition, due to a shortage of manpower, it may be difficult to support the subject with the technician's hands, and even if it is possible, it may waste the technician's physical strength.

[0004] On the other hand, when supporting the subject using an assistive device, assistive devices of various sizes or soft assistive devices such as foam materials have been conventionally used, but this may cause the subject to feel pain or move.

[0005] Therefore, it has been difficult to conveniently and appropriately support the subject during X-ray imaging.

[0044] Hereinafter, an embodiment of an X-ray diagnostic apparatus will be described with reference to the accompanying drawings. In addition, as an example of an X-ray diagnostic apparatus, an X-ray diagnostic apparatus having an upper tube type structure in which an X-ray tube is located above a subject will be described below, but the X-ray diagnostic apparatus may also be configured as a lower tube type in which an X-ray tube is located below a subject. In addition, in the following description, components having substantially the same function and structure are denoted by the same reference numerals, and repeated descriptions are given only when necessary.

[0045] Figure 1 FIG. 1 is a diagram showing a configuration example of an X-ray diagnostic apparatus 1 according to an embodiment. Figure 1 As shown, the X-ray diagnosis apparatus 1 of the embodiment includes an imaging device 10, a console 20, and a support device 30. The support device 30 is an example of a medical support device.

[0046] The imaging device 10 is a device for imaging the subject P using X-rays. The console 20 is a device for an operator to control the operation of the imaging device 10 in an operation room different from the inspection room where the imaging device 10 is installed, for example. The imaging device 10 and the console 20 are connected in a communication manner. The support device 30 is a device for supporting the subject P when imaging the subject P using X-rays. That is, the support device 30 is a device for supporting the subject P located between the X-ray tube 13 and the X-ray detector 19 described later.

[0047] like Figure 1 As shown, the imaging device 10 includes a high voltage generator 11, an X-ray tube 13, an X-ray aperture 15, a bed device 17, an X-ray detector 19, and an X-ray control circuit 111. The X-ray tube 13 is an example of an X-ray generating unit. The bed device 17 is an example of a medical bed device. The bed device 17 includes a top plate 171, a bed moving mechanism 172, and a bed mechanism control circuit 173. The console 20 includes an input interface 21, a display 23, a storage circuit 25, and a processing circuit 27. In the following description, the direction along the long side direction of the bed device 17 is defined as the Y-axis direction, the direction along the short side direction of the bed device 17 is defined as the X-axis direction, and the direction orthogonal to the X-axis direction and the Y-axis direction is defined as the Z-axis direction.

[0048] The high voltage generator 11 is a device for supplying high voltage and filament current to the X-ray tube 13. The high voltage generator 11 has a circuit such as a transformer and a rectifier and a high voltage generator. The high voltage generator has the function of generating a high voltage applied to the X-ray tube 13 and a filament current supplied to the X-ray tube 13. The X-ray control circuit 111 controls the supply of the high voltage generated by the high voltage generator and the filament current generated by the high voltage generator. The high voltage generator can be a transformer type or an inverter type.

[0049] The X-ray tube 13 irradiates the object P with X-rays. The X-ray tube 13 is a vacuum tube that generates X-rays by applying a high voltage from a high voltage generator 11 and supplying a filament current from the high voltage generator 11, thereby irradiating thermal electrons from a cathode (filament) toward an anode (target material). In the X-ray tube 13, X-rays are generated by causing thermal electrons to collide with a target material. Among the X-ray tubes 13, for example, there is a rotating anode type X-ray tube that generates X-rays by irradiating thermal electrons to a rotating anode. Not limited to the rotating anode type, any type of X-ray tube 13 can be applied. The X-ray aperture 15 reduces the X-rays irradiated from the X-ray tube 13. The X-ray aperture 15 is provided on the front surface of the X-ray radiation window in the X-ray tube 13. The X-ray aperture 15 has, for example, four aperture blades made of a metal plate such as lead.

[0050] The X-ray tube 13 and the X-ray aperture 15 are supported in a movable manner on a gantry (not shown) provided on the floor surface. The X-ray tube 13 and the X-ray aperture 15 can be rotated around a rotation axis along the X-axis and moved along the upper surface of the top plate 171, for example, by a moving mechanism (not shown) provided on the gantry.

[0051] The X-ray detector 19 detects X-rays generated by the X-ray tube 13 and transmitted through the subject P. The X-ray detector 19 is, for example, an X-ray flat panel detector (Flat Panel Detector: hereinafter referred to as FPD). The FPD has, for example, a plurality of semiconductor detection elements. Among semiconductor detection elements, there are direct conversion types that directly convert X-rays into electrical signals and indirect conversion types that convert X-rays into light using a fluorescent substance and convert the light into electrical signals. The FPD can be used in any form. The electrical signals generated by the plurality of semiconductor detection elements accompanying the incidence of X-rays are output to an analog-to-digital converter (Analogto Digital converter: hereinafter referred to as A / D converter) not shown in the figure. The A / D converter converts the electrical signal into digital data. The A / D converter outputs the digital data to the processing circuit 27. In addition, an image intensifier (Image Intensifier) ​​can also be used as the X-ray detector 19.

[0052] The bed device 17 is a device for placing the subject P. The bed device 17 is moved by the bed moving mechanism 172 under the control of the bed mechanism control circuit 173. The bed moving mechanism 172 adjusts the standing and laying down of the bed device 17 by, for example, rotating the bed device 17 around a rotation axis along the X-axis direction. The bed moving mechanism 172 includes, for example, a driving source such as a motor provided on the frame and a driving force transmission member for transmitting the driving force of the driving source to the bed device 17.

[0053] The input interface 21 receives input operations of various instructions and information from the operator. Specifically, the input interface 21 converts the input operations received from the operator into electrical signals and outputs them to the processing circuit 27. For example, the input interface 21 is implemented by a trackball, a switch button, a mouse, a keyboard, a touchpad for performing input operations by touching the operation surface, a touch screen integrating a display screen and a touchpad, a non-contact input circuit using an optical sensor, a sound input circuit, and a foot switch. In addition, the input interface 21 is not limited to an interface having physical operating components such as a mouse and a keyboard. For example, an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device that is separately provided from the device and outputs the electrical signal to a control circuit is also included in the example of the input interface 21.

[0054] The display 23 is a device that displays various information. For example, the display 23 converts image data sent from the processing circuit 27 into an electrical signal for display and outputs the signal. The display 23 is implemented by a liquid crystal monitor, a CRT (Cathode Ray Tube) monitor, a touch panel, or the like.

[0055] The storage circuit 25 is a non-temporary storage device that stores various information, such as a HDD (Hard Disk Drive), an optical disk, an SSD (Solid State Drive), and an integrated circuit storage device. The storage circuit 25 stores, for example, a control program for controlling the X-ray diagnostic device 1 and various data for executing the control program. In addition to being an HDD and an SSD, the storage circuit 25 can also be a drive device that reads and writes various information between a removable storage medium such as a CD (Compact Disc), a DVD (Digital Versatile Disc), and a flash memory, or a semiconductor storage element such as a RAM (Random Access Memory).

[0056] The processing circuit 27 is a circuit that controls the overall operation of the X-ray diagnosis apparatus 1 based on an electrical signal of an input operation input from the input interface 21. For example, the processing circuit 27 includes an imaging control function 271 and an image generation function 272.

[0057] Here, for example Figure 1 The processing functions executed by the components of the processing circuit 27 shown, namely, the shooting control function 271 and the image generation function 272, are recorded in the storage circuit 25 in the form of programs that can be executed by a computer. The processing circuit 27 is, for example, a processor. The processor constituting the processing circuit 27 reads out each program from the storage circuit 25 and executes the program to realize the function corresponding to each program read out. In other words, the processing circuit 27 that has read out the status of each program has Figure 1 The functions shown in the processing circuit 27.

[0058] In addition, Figure 1 2 shows that each processing function of the shooting control function 271 and the image generation function 272 is implemented by a single processing circuit 27, but the embodiment is not limited to this. For example, the processing circuit 27 may also be composed of a plurality of independent processors, and each processing function is implemented by each processor executing each program. In addition, each processing function of the processing circuit 27 may also be appropriately distributed or concentrated to a single or multiple processing circuits.

[0059] The imaging control function 271 controls the imaging operation of the imaging device 10 on the subject P, for example, based on the input operation received from the operator via the input interface 21. The imaging control function 271 controls the imaging operation of the subject P by controlling the X-ray control circuit 111 and the bed mechanism control circuit 173, etc. More specifically, the imaging control function 271 reads out the control program stored in the storage circuit 25 and expands it on the memory in the processing circuit 27, and controls each part of the X-ray diagnosis device 1 according to the expanded control program.

[0060] The image generation function 272 generates image data based on the output from the X-ray detector 19 . The image data is data of medical images including fluoroscopic images and radiographic images of the subject P. The imaging control function 271 displays the generated image data on the display 23 .

[0061] Figure 2 It is a perspective view showing a configuration example of the support device 30 according to the embodiment. Figure 3 It is a side view which shows the support tool 35 of the support device 30 which concerns on embodiment. Figure 4 It is a front view which shows the support tool 35 of the support device 30 which concerns on embodiment. Figure 5 It is a figure which shows the movable part 31 of the support device 30 which concerns on embodiment.

[0062] like Figure 1 to Figure 5 As shown, the support device 30 includes a movable portion 31, a sensor 32, a storage circuit 33, and a processing circuit 34. The support device 30 further includes a support tool 35, an arm portion 36, and a fixing portion 37.

[0063] The support tool 35 has a shape into which a hand can be inserted. Figure 3 and Figure 4 The arrow A in FIG. 1 represents the insertion direction and the removal direction of the hand H relative to the support device 35. Figure 4 In the example shown, the support device 35 has a five-finger glove shape. That is, the support device 35 has five branch portions 351 into which five fingers can be inserted one by one. The support device 35 is formed of a material having a rigidity that allows the hand to be inserted into the support device 35 and a flexibility that allows the fingers to be bent inside the support device 35. The support device 35 can be formed of a resin material or a rubber material. The rigidity and flexibility of the joint portion 35a provided at a position corresponding to the joint of the finger on the branch portion 351 can also be adjusted so that it is easier to bend than other parts of the branch portion 351.

[0064] like Figure 2As shown, the support device 35 is fixed to the front end of the arm 36. A fixing portion 37 for fixing the support device 30 to the bed device 17 is provided at the base end of the arm 36. The fixing portion 37 fixes the support device 30 to the top plate 171 in a detachable manner by a fixing method such as clamping or screwing.

[0065] exist Figure 2 In the example shown, a node 361 (i.e., a rotation axis) capable of changing the bending angle of the arm 36 is provided between the front end and the base end of the arm 36. By changing the bending angle of the arm 36, the posture of the support device 35 can be changed. For example, in response to the operator moving his hand while inserting his hand into the support device 35, the node 361 of the arm 36 changes the bending angle of the arm 36. A mechanical or electrical locking mechanism for maintaining the changed bending angle of the arm 36 may also be provided at the node 361 of the arm 36.

[0066] The movable part 31 is operated in accordance with the operation inside the support device 30. That is, the movable part 31 is operated in accordance with the manual operation in a state where the operator inserts his hand inside the support tool 35. Figure 5 In the example shown, the movable part 31 is provided inside the support device 35 .

[0067] exist Figure 5 In the example shown, the movable portion 31 has a plurality of plate portions 311A, 311B, 311C and a plurality of rotation limiting components 312A, 312B, 312C. The plurality of plate portions 311A, 311B, 311C are arranged adjacent to each other along the fingers. The plurality of plate portions 311A, 311B, 311C are rotatably connected at positions corresponding to the joints of the fingers. The plurality of plate portions 311A, 311B, 311C can be provided at positions in contact with the fingertips in the support device 35. Figure 5 In the example shown, a plurality of plate portions 311A, 311B, and 311C are provided along the index finger inside the branch portion 351 corresponding to the index finger. In the branch portion 351 corresponding to fingers other than the index finger, a plurality of plate portions are provided in the same manner as the index finger. However, the number of plate portions corresponding to the thumb is one less than the number of plate portions corresponding to the other fingers.

[0068] exist Figure 5In the example shown, the plate portion 311A ​​is provided along the distal phalanx at a position corresponding to the distal phalanx inside the support device 35. The plate portion 311B is provided along the middle phalanx at a position corresponding to the middle phalanx inside the support device 35. The plate portion 311C is provided along the proximal phalanx at a position corresponding to the proximal phalanx inside the support device 35. The plate portion 311A ​​is rotatably connected (i.e., supported) to the plate portion 311B at a position corresponding to the DIP (Distal Inter Phalangeal) joint inside the support device 35, with a rotation axis 313A provided at the front end of the plate portion 311B as a fulcrum. The plate portion 311B is rotatably connected to the plate portion 311C at a position corresponding to the PIP (Proximal Inter Phalangeal) joint inside the support device 35, with a rotation axis 313B provided at the front end of the plate portion 311C as a fulcrum. The plate 311C is rotatably connected to the plate 311D at a position corresponding to the MP (Metacarpal Phalangeal) joint inside the support device 35, with the rotation axis 313C on the plate 311D provided corresponding to the metacarpal bone as a fulcrum. The plate 311D may also be rotatably connected to the front end of another plate.

[0069] A plurality of rotation limiting components 312A, 312B, 312C limit the rotation of each of the plurality of plate portions 311A, 311B, 311C. The rotation limiting component 312A is disposed at a position corresponding to the rotation axis 313A of the plate portion 311A ​​to limit the rotation of the plate portion 311A. The rotation limiting component 312B is disposed at a position corresponding to the rotation axis 313B of the plate portion 311B to limit the rotation of the plate portion 311B. The rotation limiting component 312C is disposed at a position corresponding to the rotation axis 313C of the plate portion 311C to limit the rotation of the plate portion 311C. Figure 5 In the example shown, the plurality of rotation restricting members 312A, 312B, 312C include a rotor portion 3121 that rotates integrally with the corresponding plate portions 311A, 311B, 311C and a brake portion 3122 that restricts the rotation of the rotor portion 3121. For example, the rotor portion 3121 may be a magnetic body, and the brake portion 3122 may be an electromagnetic brake that generates an electromagnetic force that attracts the rotor portion 3121 when energized. Such an electromagnetic brake that restricts the rotation of the plate portion may also be applied to the locking mechanism of the node 361 of the arm portion 36.

[0070] The sensor 32 outputs a detection signal (i.e., an electrical signal) corresponding to the presence or absence of a hand. Specifically, the sensor 32 outputs a detection signal when the hand is inserted into the support device 35, and does not output a detection signal when the hand is not inserted into the support device 35. The sensor 32 outputs a detection signal corresponding to the contact of the hand with the sensor 32 from the inside of the support device 30. The contact between the hand and the sensor 32 may be direct contact or indirect contact via the support device 35 or the like. The sensor 32 may also output a detection signal according to the approach of the hand to the sensor 32. At least two sensors 32 are provided corresponding to the thumb and fingers other than the thumb. Figure 2-3 In the example shown, the finger other than the thumb is the index finger. That is, the sensor 32 is provided at two locations, the branch portion 351 corresponding to the thumb and the branch portion 351 corresponding to the index finger. The sensor 32 may be any one of a contact sensor and a non-contact sensor as long as it can output a detection signal corresponding to the presence or absence of a hand. The contact sensor may be, for example, a piezoelectric sensor. The non-contact sensor may be, for example, a photoelectric sensor and an electrostatic capacitance sensor.

[0071] Figure 1 The storage circuit 33 of the support device 30 shown is a non-temporary storage device that stores various information, such as an HDD, an optical disk, an SSD, and an integrated circuit storage device. The storage circuit 33 stores, for example, a control program for controlling the movable part 31 and various data for executing the control program. In addition to being an HDD and an SSD, the storage circuit 33 can also be a drive device that reads and writes various information between a removable storage medium such as a CD, a DVD, and a flash memory, or a semiconductor storage element such as a RAM. The storage circuit 33 can be provided, for example, on the support device 35, or can also be provided on the fixed part 37.

[0072] The processing circuit 34 of the support device 30 is a circuit that controls the movement of the movable part 31 according to the electrical signal input from the sensor 32. For example, the processing circuit 34 has a detection function 341 and a motion control function 342. The detection function 341 is an example of a detection part. The motion control function 342 is an example of a motion control part. The processing circuit 34 can be provided in the support device 35, or can also be provided in the fixing part 37.

[0073] Here, for example, Figure 1The processing functions performed by the components of the processing circuit 34 shown, namely the detection function 341 and the action control function 342, are recorded in the storage circuit 33 in the form of a program that can be executed by a computer. The processing circuit 34 is, for example, a processor. The processing circuit 34 may also include circuits other than the processor. The processor constituting the processing circuit 34 reads out each program from the storage circuit 33 and executes the program to realize the function corresponding to the read program. In other words, the processing circuit 34 that has read out the status of each program has Figure 1 The functions shown within the processing circuit 34.

[0074] In addition, Figure 1 3 shows that the processing functions of the detection function 341 and the action control function 342 are implemented by a single processing circuit 34, but the embodiment is not limited to this. For example, the processing circuit 34 may also be composed of a plurality of independent processors, and each processor executes each program to implement each processing function. In addition, each processing function of the processing circuit 34 may also be appropriately distributed or concentrated to a single or multiple processing circuits for implementation.

[0075] The detection function 341 detects the presence of a hand based on the detection signal output by the sensor 32. The motion control function 342 controls the motion of the movable unit 31 so as to support the subject P based on the detection result of the presence of a hand obtained by the detection function 341.

[0076] Specifically, when a hand is detected by the detection function 341, the motion control function 342 allows the movable part 31 to move in accordance with the movement of the hand (i.e., the manual operation of the operator). On the other hand, when a hand is not detected by the detection function 341, the motion control function 342 allows the movable part 31 to support the subject P by restricting the movement of the movable part 31.

[0077] exist Figure 5 In the example shown, when a hand is detected by the detection function 341, the motion control function 342 allows the motion of the movable part 31 by controlling the plurality of rotation restricting members 312A, 312B, 312C so as not to restrict the rotation of each of the plurality of plate parts 311A, 311B, 311C. For example, the motion control function 342 does not energize the plurality of brake parts 3122 so that each brake part 3122 does not generate an electromagnetic force that attracts the corresponding rotor part 3121. On the other hand, when a hand is not detected by the detection function 341, the motion control function 342 restricts the motion of the movable part 31 by controlling the plurality of rotation restricting members 312A, 312B, 312C so as to restrict the rotation of each of the plurality of plate parts 311A, 311B, 311C. For example, the motion control function 342 energizes the plurality of brake parts 3122 so that each brake part 3122 generates an electromagnetic force that attracts the corresponding rotor part 3121.

[0078] When an electromagnetic brake is provided at the node 361 of the arm 36, the motion control function 342 may control the electromagnetic brake so as not to restrict the rotation of the arm 36 when the hand is detected by the detection function 341. In addition, when the hand is not detected by the detection function 341, the motion control function 342 may control the electromagnetic brake so as to restrict the rotation of the arm 36.

[0079] Next, an operation example of the support device 30 according to the embodiment configured as above will be described. Figure 6 : is a flowchart showing an example of the operation of the support device 30 according to the embodiment. Figure 6 The flowchart is repeated as needed. Figure 6 In the initial state, it is assumed that the operator's hand is not inserted into the support device 35. Figure 6 In the initial state, the sensor 32 does not output a detection signal, and the detection function 341 does not detect the hand. Therefore, the movable part 31 is in a locked state in which the movement is restricted by the movement control function 342. And, starting from the initial state, first, as Figure 6 As shown, the detection function 341 determines whether the operator's hand is inserted into the support tool 35, that is, determines the presence or absence of the hand, based on whether the detection signal is output from the sensor 32 (step S1).

[0080] When the operator's hand is inserted into the support device 35 (step S1: Yes), the motion control function 342 releases the locked state of the movable part 31 (step S2). Specifically, the motion control function 342 allows the movement of the movable part 31 by controlling the plurality of rotation restriction members 312A, 312B, 312C so as not to restrict the rotation of each of the plurality of plate parts 311A, 311B, 311C. For example, the motion control function 342 prevents the brake part 3122 from generating an electromagnetic force that attracts the rotor part 3121 by not energizing the brake part 3122. On the other hand, when the operator's hand is not inserted into the support device 35 (step S1: No), the detection function 341 repeats the determination of whether the operator's hand is inserted into the support device 35 (step S1).

[0081] Figure 7 2 is a perspective view showing an example of the operation of the support device 30 according to the embodiment. Figure 7 As shown in FIG. 1 , when the operator's hand H is inserted into the support device 35, the locked state of the movable portion 31 is released, so that the operator can adjust the bending amount of the finger in the support device 35. Since the bending amount of the finger can be adjusted, the support target part (for example, the position of the support target part) of the subject P supported by the support device 35 can be adjusted. Figure 7 The supporting force (i.e., holding force) of the knee in the middle.

[0082] After the locking state of the movable part 31 is released, Figure 6 As shown, the detection function 341 determines whether the operator's hand is inserted into the support tool 35 based on whether the detection signal is output from the sensor 32 (step S3).

[0083] When the operator's hand is not inserted into the support device 35 (step S3: No), the motion control function 342 puts the movable part 31 into a locked state (step S4). Specifically, the motion control function 342 controls the plurality of rotation limiting members 312A, 312B, 312C to limit the rotation of each of the plurality of plate parts 311A, 311B, 311C, thereby limiting the motion of the movable part 31. For example, the motion control function 342 energizes the brake part 3122 so that the brake part 3122 generates an electromagnetic force that attracts the rotor part 3121. On the other hand, when the operator's hand is inserted into the support device 35 (step S3: Yes), the detection function 341 repeatedly determines whether the operator's hand is inserted into the support device 35 (step S3).

[0084] Figure 8 Then Figure 7 A three-dimensional diagram showing an example of operation of the support device 30 according to the embodiment. Figure 8 As shown in FIG. 1 , in the locked state, the movable portion 31 maintains the operation state (e.g., the rotation angle of the plate portions 311A, 311B, and 311C) immediately before the operator's hand H is released from the support device 35. Therefore, the movable portion 31 can maintain the support force on the support target portion of the subject P adjusted when the operator inserts the hand H into the support device 35. Thus, the support device 30 can appropriately support the support target portion of the subject P even after the operator releases the hand H from the support device 35.

[0085] As described above, in the support device 30 of the embodiment, the movable portion 31 moves according to the operation inside the support device 30 .

[0086] Thus, when an operation is performed on the inner side of the support device 30, the support force on the subject P can be intuitively adjusted by the movement of the movable part 31 corresponding to the operation, and when the operation is not performed, the movement of the movable part 31 can be restricted to maintain the support force. Therefore, the support force can be intuitively adjusted by a simple operation on the inner side of the support device 30, and through this adjustment, an appropriate support force can be applied to the subject P. Thus, the subject P can be simply and appropriately supported. In addition, by appropriately supporting the subject P, the imaging position of the subject P can be appropriately maintained. By appropriately maintaining the imaging position of the subject P, the subject P can be appropriately imaged. In addition, since the operator does not need to continuously support the subject P during imaging, the radiation dose can be reduced, and the operator's labor can be reduced. In addition, since the subject P can be supported and imaged by one operator, it is also possible to eliminate manpower shortages.

[0087] In addition, in the support device 30 of the embodiment, the sensor 32 outputs a detection signal corresponding to the presence or absence of the hand H. In addition, the detection function 341 detects the presence or absence of the hand H based on the detection signal output by the sensor 32. In addition, the motion control function 342 controls the motion of the movable part 31 to support the subject P based on the detection result of the presence or absence of the hand H obtained by the detection function 341.

[0088] Thus, whether or not an operation is performed inside the support device 30 can be easily and appropriately grasped based on the detection signal of the sensor 32, and the operation of the movable portion 31 can be controlled, so that the subject P can be supported more easily and appropriately.

[0089] In addition, in the support device 30 of the embodiment, when the hand H is detected by the detection function 341, the motion control function 342 allows the movable part 31 to move in accordance with the movement of the hand H. In addition, when the hand H is not detected by the detection function 341, the motion control function 342 allows the movable part 31 to support the subject P by restricting the movement of the movable part 31.

[0090] Thus, adjustment of the support force by the operator and maintenance of the support force by the movable portion 31 can be switched easily and appropriately based on the detection result of the detection function 341 , so that the subject P can be supported more easily and appropriately.

[0091] In addition, in the support device 30 of the embodiment, the movable part 31 has a plurality of plate parts 311A, 311B, 311C and a plurality of rotation limiting parts 312A, 312B, 312C. The plurality of plate parts 311A, 311B, 311C are arranged adjacent to each other along the fingers and are rotatably connected at positions corresponding to the joints of the fingers. The plurality of rotation limiting parts 312A, 312B, 312C limit the rotation of each of the plurality of plate parts 311A, 311B, 311C. When the hand H is detected by the detection function 341, the motion control function 342 allows the motion of the movable part 31 by controlling the plurality of rotation limiting parts 312A, 312B, 312C so as not to limit the rotation of each of the plurality of plate parts 311A, 311B, 311C. When the detection function 341 does not detect the hand H, the motion control function 342 controls the rotation restriction members 312A, 312B, and 312C to restrict the rotation of each of the plate portions 311A, 311B, and 311C, thereby restricting the motion of the movable portion 31 .

[0092] Thus, when the hand H is detected by the detection function 341, the rotation of the plurality of plate portions 311A, 311B, and 311C along the fingers is not restricted, and thus the operator can adjust the supporting force more simply and intuitively. In addition, when the hand H is not detected by the detection function 341, the rotation of the plurality of plate portions 311A, 311B, and 311C is restricted, and thus the supporting force of the movable portion 31 adjusted by the operator can be simply and appropriately maintained. Therefore, the subject P can be supported more simply and appropriately.

[0093] Furthermore, in the support device 30 of the embodiment, the sensor 32 outputs a detection signal in response to contact of the hand from the inside of the support device 30 .

[0094] Thereby, the presence or absence of a hand can be detected easily and appropriately, and therefore the subject P can be supported more easily and appropriately.

[0095] In addition, in the support device 30 of the embodiment, at least two sensors 32 are provided corresponding to the thumb and fingers other than the thumb.

[0096] Thus, the presence or absence of a hand can be appropriately detected by at least two sensors 32 provided at appropriate positions, so that the subject P can be supported more appropriately.

[0097] In addition, in the support device 30 of the embodiment, the finger other than the thumb is the index finger.

[0098] Thus, by providing the sensor 32 at the position corresponding to the thumb and index finger which are important for supporting the subject P, the adjustment of the support force by the operator and the maintenance of the support force by the movable part 31 can be switched more appropriately. Therefore, the subject P can be supported more appropriately.

[0099] In addition, in the support device 30 of the embodiment, the support device 30 further includes a support tool 35 having a shape into which a hand can be inserted.

[0100] Thus, the operator can support the subject P via the support tool 35 while inserting the hand into the support tool 35, and can therefore more intuitively adjust the support force. Therefore, the subject P can be supported more simply and appropriately.

[0101] Furthermore, in the support device 30 of the embodiment, the movable portion 31 is provided inside the support tool 35 .

[0102] Thus, the operator can move the movable portion 31 according to the movement of the fingers while inserting the hand into the support tool 35, and can adjust the support force more intuitively. Therefore, the subject P can be supported more simply and appropriately.

[0103] Furthermore, the support device 30 of the embodiment is fixed to the top plate 171 of the bed device 17 .

[0104] This allows the subject P to be appropriately supported during imaging in the supine position.

[0105] Various modifications described below can be applied to the embodiments.

[0106] (First Modification)

[0107] First, a first modified example in which the shape of the support tool 35 is different will be described. Fig. 9 FIG. 1 is a top view of a support device 30 according to a first modified example of the embodiment. In the above-mentioned embodiment, an example of a support device 35 in the shape of a glove having five fingers is described. Fig. 9 In the example shown, the support tool 35 has a mitten shape. That is, the support tool 35 has two branch parts 351 corresponding to the thumb and the fingers other than the thumb. Two sensors 32 are provided corresponding to the two branch parts 351.

[0108] According to the first modification, since the support tool 35 has a mitten shape, the hand can be easily inserted into and removed from the support tool 35 .

[0109] (Second Modification)

[0110] Next, a second modification example in which the subject P is supported by both hands will be described. Fig.10 2 is a side view of a support device showing a second modified example of the embodiment. Fig.10As shown, the X-ray diagnosis apparatus 1 of the second modification example includes two types of support devices 30A and 30B, namely a support device 30A for the right hand and a support device 30B for the left hand, in order to maintain the support force of the operator's both hands on the subject P.

[0111] The right hand support device 30A and Figure 2 The left-hand support device 30B has a mirror-symmetrical shape with respect to the right-hand support device 30A. In addition, the right-hand support device 35 and the structural parts 31 and 32 provided on the support device 35 and the left-hand support device 35 and the structural parts 31 and 32 provided on the support device 35 may share a part of the fixing part 37 and the arm part 36.

[0112] According to the second modification, by limiting the movement of the movable part 31 of the right-hand support device 30A, the support force of the operator's right hand can be maintained. In addition, by limiting the movement of the movable part 31 of the left-hand support device 30B, the support force of the operator's left hand can be maintained. Thus, the subject P can be supported more appropriately.

[0113] (Third Modification)

[0114] Next, a third modified example of fixing the support device 30 to the ceiling will be described. Fig.11 2 is a perspective view showing a support device 30 according to a third modified example of the embodiment. In the above-mentioned embodiment, an example of the support device 30 fixed to the top plate 171 of the bed device 17 is described. Fig.11 In the example shown, the support device 30 is fixed to the ceiling.

[0115] Specifically, the fixing portion 37 of the support device 30 is supported by a rail 115 provided on the ceiling so as to be movable along the long side direction of the rail 115, that is, the Y-axis direction. The support device 35 and the structural parts 31 and 32 (not shown) provided on the support device 35 are suspended from the rail 115 via the fixing portion 37 and the arm portion 36. In addition, the operation box 14 having the X-ray tube 13 and the X-ray diaphragm 15 is suspended on the rail 115 via the support portion 119 supported so as to be slidable along the rail 115 and the support column portion 117 extending downward from the support portion 119. The operator can freely set the distance and direction to the X-ray detector 19 by operating the operation box 14.

[0116] According to the third modification, since the support device 30 can be fixed to the ceiling, the degree of freedom in installing the support device 30 can be improved.

[0117] (Fourth Modification)

[0118] Next, a fourth modification example of supporting the subject P during imaging in the standing position will be described. Fig.12 FIG. 4 is a perspective view showing a support device 30 according to a fourth modified example of the embodiment. In the above-mentioned embodiment, an example of the support device 30 supporting the subject P during imaging in a supine position is described. Fig.12 In the example shown, the support device 30 supports the subject P during imaging in a standing position.

[0119] Specifically, the support device 30 is supported by a gantry 121 installed on the floor surface. The X-ray detector 19 is supported on the gantry 121 in an orientation perpendicular to the floor surface. The orientation of the operation box 14 is adjusted to irradiate the subject P located in front of the X-ray detector 19 with X-rays. The support device 30 supports the subject P located in front of the gantry 121, i.e., the X-ray detector 19. Fig.12 In the example shown, the support device 30 supports the elbow of the subject P.

[0120] According to the fourth modification, since the subject P can be supported during imaging in a standing position, the convenience and versatility of the support device 30 can be improved.

[0121] (Fifth Modification)

[0122] Next, a modification of the movable portion 31 will be described. Fig.13 1 is a diagram showing a movable portion 31 of a support device 30 according to a fifth modified example of the embodiment. In the above-described embodiment, an example is described in which a plurality of rotation limiting components 312A, 312B, 312C of the movable portion 31 have a rotor portion 3121 that rotates integrally with the corresponding plate portions 311A, 311B, 311C and a brake portion 3122 that limits the rotation of the rotor portion 3121. In contrast, in Fig.13 In the example shown, the plurality of rotation restricting members 312A, 312B, and 312C include a motor 3123 and a clutch 3124 that connects or disconnects the motor 3123 to or from the corresponding rotation shafts 313A, 313B, and 313C. The clutch 3124 is, for example, an electromagnetic clutch.

[0123] When the hand is detected by the detection function 341, the motion control function 342 causes each clutch part 124 to disconnect the motor 3123 from the rotation shafts 313A, 313B, and 313C by not energizing the plurality of clutch parts 3124. Thus, the rotation of each plate part 311A, 311B, and 311C about the rotation shafts 313A, 313B, and 313C is not restricted, so the operator can adjust the support force on the subject P by moving the fingers.

[0124] On the other hand, when the hand is not detected by the detection function 341, the motion control function 342 energizes the plurality of clutch parts 3124 so that each clutch part 124 connects the motor 3123 to the rotating shafts 313A, 313B, and 313C. When the motor 3123 is connected to the rotating shafts 313A, 313B, and 313C, the motion control function 342 energizes the motor 3123 so that the motor 3123 is locked. Thus, the rotation of each of the plurality of plate parts 311A, 311B, and 311C is restricted, so that the movable part 31 can maintain the supporting force adjusted by the operator. In addition, when the hand is not detected by the detection function 341, the motion control function 342 can also rotate the drive motor 3123 in the direction of holding the hand to apply an appropriate torque to the subject P.

[0125] According to the fifth modification, the degree of freedom in designing the movable portion 31 can be increased.

[0126] (Sixth Modification)

[0127] Fig.14 1 is a block diagram showing a configuration example of an X-ray diagnosis apparatus 1 according to a sixth modification of the embodiment. In the above-mentioned embodiment, the support device 30 alone includes the storage circuit 33 and the processing circuit 34. In contrast, Fig.14 As shown in FIG. 1 , the storage circuit 33 and the processing circuit 34 of the support device 30 may be integrated with the storage circuit 25 and the processing circuit 27 of the console 20. That is, the processing circuit 27 of the console 20 may include a detection function 341 and a motion control function 342. In addition, in addition to the detection vibration based on the sensor 32, the motion control function 342 may control the motion of the movable part 31 by remote operation based on the electrical signal of the input operation from the input interface 21.

[0128] In addition, the term "processor" used in the above description refers to circuits such as a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or an Application Specific Integrated Circuit (ASIC), a programmable logic device (such as a Simple Programmable Logic Device (SPLD), a Complex Programmable Logic Device (CPLD), and a Field Programmable Gate Array (FPGA)). The processor implements its functions by reading out and executing programs stored in a storage circuit. In addition, instead of storing the program in the storage circuit, it is also possible to directly load the program into the circuit of the processor. In this case, the processor implements its functions by reading out and executing the program loaded into the circuit. In addition, the processor is not limited to a circuit configured as a single processor, and a plurality of independent circuits may be combined to form a processor to implement its functions. Moreover, it is also possible to Figure 1 Multiple components in a chip are integrated into one processor to realize its functions.

[0129] According to at least one of the embodiments described above, the subject can be supported simply and appropriately.
