Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a medical X-ray inspection device. Background Art

[0002] In the field of X-ray medical photography and examination, such as X-ray gastrointestinal machines, when performing gastrointestinal examinations, it is usually necessary to use a compressor to provide external force to compress the stomach, intestines and other tissues or organs. When examining other parts of the body, the compressor is required to be out of the X-ray field. At present, it is necessary to remove or fold the compressor from the X-ray gastrointestinal machine so that the compressor or the compression rod is out of the X-ray field, and the existing methods or structures for folding or disassembling the compressor are complex and cumbersome. Summary of the invention

[0003] In view of this, the present disclosure proposes, on the one hand, a compressor for providing external compressive force to the imaged organs during X-ray medical examinations. The compressor has a simple structure and its compression rod can be automatically folded, so that the compressor can leave the X-ray field range in applications other than providing external compressive force to the organs, so as not to hinder the X-ray examination device from performing other medical imaging examinations. The compressor comprises: a base; a compression rod for providing a compression force to the photographed organ, the compression rod being connected to the base and being able to move relative to the base; a motor, the compressor moves along a lifting rod under the drive of the motor, and drives the compression rod through a transmission device to change its position; a clutch, the compression rod is installed in cooperation with the clutch, and the compression rod is disengaged from the limit position with the base or is limited to the base under the action of the clutch being in an engaged state or a disengaged state; and a first sensor, which is configured to feed the clutch with horizontal position information of the compressor, wherein the clutch is triggered to be in an engaged state according to the horizontal position information fed by the first sensor, wherein when the clutch is in an engaged state, the compression rod is in a first state of being disengaged from the limit position with the base, and the motor changes the position of the compression rod by driving the transmission device, and when the clutch is in a disengaged state, the compression rod is in a second state of being limited to the base, and the motor cannot change the position of the compression rod by driving the transmission device.

[0004] Optionally, the clutch of the compressor includes a first half-clutch and a second half-clutch, the first half-clutch and the second half-clutch are respectively provided with a first through hole so that a pin can pass through the first through hole and move, and the first half-clutch is fixed to the transmission device, and a second through hole is opened at a position of the compression rod corresponding to the first through hole, so that the pin can move in the second through hole, wherein at least one limiting hole corresponding to the pin is provided on the base, so that when the clutch is in an engaged state, the second half-clutch and the first half-clutch are close to each other, the pin is disengaged from the first limiting hole, and the compression rod is in the first state of being disengaged from the base, and when the clutch is in a disengaged state, the second half-clutch and the first half-clutch are away from each other, the pin cooperates with the first limiting hole to limit, and the compression rod is in the second state of being limited on the base.

[0005] Optionally, the compressor is provided with a first limiting hole at a first position of the base for cooperating with the latch for limiting the position, and when the latch cooperates with the first limiting hole for limiting the position, the compression rod is located at a position extending along the horizontal direction of the base, and a second limiting hole is provided at a second position of the base for cooperating with the latch for limiting the position, so that when the compression rod is rotated so that the latch cooperates with the second limiting hole for limiting the position, a certain angle is formed between the compression rod and the base.

[0006] Optionally, the second sensor of the compressor is configured to feed the rotational position information of the compression rod to the clutch by sensing a first sensing position and a second sensing position provided at the clutch. The clutch can rotate along with the compression rod, and the rotational position information corresponding to the compression rod is determined by determining the rotational position of the clutch. The clutch is triggered to be in a disengaged state according to the fed rotational position information, and controls the pin to cooperate with the first limiting hole or the second limiting hole to limit.

[0007] Optionally, the compressor sets a third limiting hole on the transmission device at a corresponding position of the pin, so that when the clutch is in the engaged state, one end of the pin leaves the limiting fit with the base, and the other end of the pin moves into the third limiting hole and limits the fit with the transmission device.

[0008] Optionally, the compressor also includes: a second sensor, configured to feed the rotational position information of the compression rod to the clutch; and the compressor moves along a lifting rod driven by the motor, and when the clutch is triggered to be in an engaged state according to the specific horizontal position information fed by the first sensor, during the process in which the compression rod rotates driven by the motor, the clutch is further triggered to be in a disengaged state according to the rotational position information fed by the second sensor, so that the compression rod is limited to the base.

[0009] Optionally, the transmission device of the compressor includes a first pulley mounted on the base, and a synchronous belt for transmitting the power of the motor to drive the first pulley to move. The first pulley is connected to the compression rod through a hinge shaft, so that the motor can drive the compression rod to move when driving the first pulley to move. The clutch is connected to the compression rod through the hinge shaft so as to rotate synchronously with the pulley rod.

[0010] Optionally, the motor of the compressor is driven by a second pulley output, and the synchronous belt is installed between the first pulley and the second pulley to drive the first pulley to rotate, and at least one tensioning wheel is provided, so that the synchronous belt is installed between the first pulley and the second pulley through the tensioning wheel to guide the synchronous belt.

[0011] On the other hand, the present disclosure provides an X-ray inspection device, comprising: a lifting rod; an X-ray camera; and a compressor as described above, which is installed on the lifting rod and guides the compressor along the lifting rod to adjust the horizontal position of the compressor, wherein when the compression rod of the compressor is extended in the horizontal direction along the compressor base, the compression rod is located in the field of view of the X-ray camera, and the compression rod is driven by a motor to adjust the angle between it and the base until the compression rod leaves the field of view.

[0012] Optionally, a height sensing mark is set on the lifting rod of the X-ray inspection device, and the first sensor is configured to feed the compressor to the clutch to pass through the height sensing mark to trigger the clutch to be in an engaged state. When the compressor passes through the height sensing mark from top to bottom, the clutch is triggered to be in an engaged state, and the motor drives the compression rod to rotate from an initial position to extend horizontally along the base. The clutch is configured so that when the second sensor senses that the compression rod extends horizontally along the base, the clutch is triggered to be in a separated state, so that the compression rod is limited to the base. When the compressor passes through the height sensing mark from bottom to top, the clutch is triggered to be in an engaged state, and the motor drives the compression rod to rotate from the initial position to be perpendicular to the base for folding. The clutch is configured so that when the second sensor senses that the compression rod is perpendicular to the base for folding, the clutch is triggered to be in a separated state, so that the compression rod is limited to the base.

[0013] One advantage provided by the present disclosure is that the compression rod of the compressor can be driven by a motor to adjust the rotational position to achieve the folding of the compressor, so that when the compressor needs to apply external force to the internal organs, such as the stomach, intestines, etc., the compression rod can remain unfolded, and after the external force is applied to the internal organs, the compression rod can be folded and leave the field of view of the X-ray camera under the action of the motor. The folding and driving structure of the compressor is simple and easy to use.

[0014] Another advantage of the present disclosure is that a clutch is used to provide attraction or separation to act on the compression rod, and the compression rod is further matched with a limiting structure, so that when the compression rod needs to be unfolded or folded, the compression rod is separated from the limiting structure under the attraction of the clutch, and when the compressor needs to remain unfolded or folded, the compression rod cooperates with the limiting structure under the separation action of the clutch. Therefore, the present disclosure provides a simple and convenient mechanism for controlling the folding of the compression rod and applying external force to the internal organs.

[0015] Another advantage is that a motor provided at the compressor base for providing driving force for the compressor to move along the lifting rod can be used to drive the rotation of the compression rod to achieve the extension and folding of the compression rod, which has the advantages of simple structure and low cost.

[0016] Another advantage is that a first sensor is set on the compressor to sense the horizontal position information of the compressor, so as to trigger the compression rod to leave a limit position and move under the drive of the motor, and a second sensor is used to sense the rotation position of the compression rod, and when the target limit position is sensed, the compression rod is triggered to be limited at the limit position, thereby realizing the connection between the movement of the compressor and the rotation of the compression rod, and improving the user experience.

[0049] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings, in which the same reference numerals represent the same parts.

[0050] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0051] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0052] In this article, "one" not only means "only one", but also means "more than one". In this article, "first", "second", etc. are only used to distinguish each other, rather than to indicate their importance and order, or the premise of each other's existence.

[0053] The compressor on the existing X-ray gastrointestinal machine includes a plug-in structure. When the compressor is needed to provide external compressive force to the organs to be imaged by X-rays, such as the intestines, stomach and other organs, the user can manually install the compression rod on the base of the compressor. When other organs need to be examined or inspected, the compression rod needs to be manually removed from the base of the compressor to make the field of view of the X-ray camera unobstructed. The above manual removal operation is troublesome and inefficient. In the existing solution, the compressor is constructed as a structure that can be automatically folded, that is, when the compressor is needed, the compressor can be unfolded to compress the gastrointestinal tract for examination, and when the compressor is not needed for examination, the compressor can be automatically folded to leave the field of view of the X-rays, but the structure of the existing foldable compressors is very complicated.

[0054] The compressor and X-ray inspection device provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0055] Figure 1 1 is a schematic structural diagram showing an X-ray inspection device 10 equipped with a compressor 100 according to an exemplary embodiment and a compression rod of the compressor 100 when unfolded.

[0056] like Figure 1 As shown, an X-ray inspection device 100, such as an X-ray gastrointestinal machine, includes: a compressor 100 for providing compression to the imaged organs, such as the intestines and stomach, during X-ray medical examination, the compressor 100 can be installed on a lifting rod 20, and the compressor 100 can be guided to move on the lifting rod 20, for example, by connecting a friction wheel (not shown) through a reducer (not shown), the friction wheel can be pressed against the lifting rod 20, and realize the movement on the lifting rod 20 through, for example, a guide mechanism, and use the first motor 103 to output forward and reverse drive, so as to adjust the position of the compressor 100 according to patients of different body shapes to better apply compression force, and an X-ray camera 30, which can be set to project X-rays vertically upward.

[0057] like Figure 1As shown, according to some embodiments of the compressor 100, when there is no need to compress the organ, in order to automatically fold the compression rod to leave the field of view of the X-ray camera 30, the compressor 100 includes: a base 101; a compression rod 102, the compression rod 102 has a pressing head, which is used to provide a compressive external force to the imaged organ, such as the intestines and stomach, and the compression rod 102 is connected to the base 101 and can move relative to the base 101; a first motor 103, which drives the compression rod 102 through a transmission device to change its position, such as rotating the compression rod 102; a clutch 107, the compression rod 102 is installed in conjunction with the clutch 107, and the compression rod 102 is disengaged from the limit position of the base 101 or is limited to the base 101 when the clutch 107 is in an engaged state or a disengaged state; and a first sensor, which is set To feed the clutch 107 with the horizontal position information of the compressor 102, wherein the clutch 107 is triggered to be in an engaged state according to the specific horizontal position information fed by the first sensor, wherein when the clutch 107 is in the engaged state so that the compression rod 102 is in a first state of being disengaged from the limit position of the base 101, the first motor 103 changes the position of the compression rod 102 by driving the transmission device to extend the compression rod 102 or retract and fold the compression rod 102, and when the clutch 107 is in a disengaged state so that the compression rod 102 is in a second state of being limited to the base 101, the first motor 103 cannot change the position of the compression rod 102 by driving the transmission device, that is, when the compression rod 102 is limited to the base 101, the first motor 103 drives the compression rod 102 to be in an idling state through the transmission device. It is easy to understand that the first motor 103 can output a forward rotation drive and a reverse rotation drive to drive the compression rod 102 to rotate or move to a certain extent under the action of the first motor 103 outputting a forward rotation, and the compression rod 102 returns to its original position under the action of the first motor 103 outputting a reverse rotation. It should be noted that the first motor 103 can provide a rotation drive for the compression rod 102 to fold, and can also provide a drive for the compressor 100 to be guided on the support rod 20 to adjust the horizontal position of the compressor 100 on the support rod 20. For example, when the compression rod 102 is limited with the base 101, the first motor 103 can still drive the compressor 100 to move in one direction along the support rod 20.

[0058] It should be noted that a height sensing mark 201 is set at a specific horizontal position, for example, at a specific height position along the lifting rod 20. After the first sensor senses the horizontal position information of the height sensing mark 201, the horizontal position information is fed to the clutch 107 and triggered to be in the engaged state.

[0059] Figure 2 FIG. 2 is a schematic diagram showing an AA cross-sectional structure of a clutch of a compressor 100 according to an exemplary embodiment when the clutch is in a disengaged state. Figure 4 FIG. 2 is a schematic diagram showing the AA cross-sectional structure of a clutch of a compressor 100 according to an exemplary embodiment when the clutch is in an engaged state.

[0060] like Figure 2 and Figure 4 As shown, according to some embodiments of the compressor 100, the clutch 107 includes a first half clutch 1071 and a second half clutch 1072, and a latch 109 for limiting the position, and the first half clutch 1071 and the second half clutch 1072 are respectively provided with a first through hole 1073 so that the latch 109 can move in the first through hole 1073, that is, the latch 109 can pass through the first half clutch 1071 and the second half clutch 1072 in the first through hole 1073 and move, and the first half clutch 1071 can be fixed to the transmission device, for example, installed with a first pulley 104. Considering that the latch 109 needs to be limited to the base 101, a second through hole 1021 is opened at the position of the pressure rod 102 corresponding to the first through hole 1073, so that the latch 109 can move in the second through hole 1021. For example, the latch 109 moves along with the action of the clutch 107 being engaged or separated, so that the second half clutch 1072 is still connected through the latch 109 and the pressure rod 102 under the action of the clutch 107 being engaged or separated. At least one limiting hole is arranged at the position, so that when the clutch 107 is in the engaged state, the second half clutch 1072 and the first half clutch 1071 are close to each other, the latch 109 is disengaged from the limiting hole, and the pressure rod 102 is in the first state of being disengaged from the base limiting state; when the clutch 107 is in the disengaged state, the second half clutch 1072 and the first half clutch 1071 are away from each other, the latch 109 moves to cooperate with the limiting hole for limiting, and the pressure rod 102 is in the second state of being limited to the base 101.

[0061] According to some embodiments of the compressor 100, the position and number of the limiting holes provided on the base 101 can correspond to the position of the compression rod 102. For example, the compression rod 102 and the clutch 107 rotate together, and the latch 109 as a limiting member also rotates relative to the base 101. Therefore, a first limiting hole 1011 is provided at the first position of the base 101 to cooperate with the latch 109 for limiting. When the compression rod 102 moves to or is located at the position where the latch 109 cooperates with the first limiting hole 1011 for limiting, the compression rod 102 moves along the base 101. 101 extends horizontally, that is, at this time, the compression rod 102 forms an angle of 180 degrees with the base, and a second limiting hole 1012 is provided at the second position of the base 101 to cooperate with the pin 109 for limiting. When the compression rod 102 is rotated to the position corresponding to the pin 109 and the second limiting hole 1012 and cooperates for limiting, a certain angle is formed between the compression rod 102 and the base 101. For example, the compression rod 102 can be rotated to form an angle of 90 degrees, vertical or smaller with the base 101, to ensure that the compression rod 102 leaves the field of view of the X-ray camera 30.

[0062] like Figure 4 As shown, according to some embodiments of the compressor 100, a third limiting hole 1041 is provided on the transmission device at a position corresponding to the latch 109, so that when the clutch 107 is in the engaged state, one end of the latch 109 leaves the limiting cooperation with the base 101, such as the first limiting hole 1011 or the second limiting hole 1012 of the base 101, and the other end of the latch 109 moves into the third limiting hole 1041 to limit the transmission device. Here, the transmission device can be a first pulley 104 installed on the base 101, and the drive of the first motor 103 is transmitted to the first motor 103 through a synchronous belt 105. The first pulley 104 can have a third limiting hole 1041 at a position relative to the latch 109, so that the latch 109 is limited to the first pulley 104 through the cooperation of the third limiting hole 1041.

[0063] According to some embodiments, Figure 1 , 3 As shown in Figure 5, the compressor 100 also includes: a first sensor (not shown), which is configured to feed horizontal position information of the compressor 100 to the clutch 107, for example, through the positive and reverse driving output of the first motor 103 to determine whether the compressor moves from top to bottom or from bottom to top, and through the positive and reverse driving output of the first motor 103 to determine the direction of movement, and the compressor 100 moves along a lifting rod 20 under the drive of the first motor, and the clutch 107 is triggered to be in an engaged state according to the horizontal position information about the compressor 100 fed by the first sensor.

[0064] According to some embodiments of the compressor 100, the second sensor 1013 may be further configured to feed the rotational position information of the compression rod 102 to the clutch 107, so that the clutch 107 is triggered to be in a disengaged state according to the fed rotational position information. For example, the second sensor 1013 senses that the compression rod 102 moves to a specific position relative to the base 101, and the compression rod 102 and the base 101 are horizontally extended or vertically positioned. If it is necessary to maintain the state at the above position, such as the compression rod 102 and the base 101 are horizontally extended and apply pressure to the organ, or the compression rod 102 and the base 101 are vertically extended, the compression rod 102 and the base 101 are horizontally extended and apply pressure to the organ, and the compression rod 102 and the base 101 are vertically extended. 01 is vertical, the clutch 107 is in a disengaged state, the latch 109 for limiting moves to the first limiting hole 1011 or moves to the second limiting hole 1012. If it is necessary to adjust the pressure rod 102 and the base 101 from the horizontally extended position to the vertical position or vice versa, the clutch 107 is triggered to be in an engaged state, and the first motor 103 can control the pressure rod 102 to rotate to the target position until the second sensor 1013 senses the target position, so as to feed the clutch 107 with the rotation position information to trigger it to be in a disengaged state, etc., so that the pressure rod 102 and the base 101 are limited. Here, the second sensor 1013 is, for example, a photoelectric switch, which can sense the light sensing mark on the rotating object to determine the rotation position information. In addition, in an exemplary embodiment, the second sensor 1013 can feed the rotation position information to a controller, and then the controller feeds the information to the clutch 107 to control its action.

[0065] According to some embodiments, in order to limit the clutch 107 to a position where the pressure rod 102 is moved horizontally or perpendicularly to the base 101 under the drive of the first motor 103 after the clutch 107 is triggered to be in the engaged state, the second sensor 1013 of the compressor 100 can also be configured to feed the clutch 107 with rotational position information of the pressure rod 102, and the compressor 100 moves along a lifting rod 20 under the drive of the first motor 103, and when the clutch 107 is triggered to be in the engaged state according to the specific horizontal position information fed by the first sensor, during the process in which the pressure rod 102 rotates under the drive of the first motor 103, the clutch 107 is triggered to be in the disengaged state according to the rotational position information fed by the second sensor 1013, and the pressure rod 102 is limited to the base 101.

[0066] Figure 3 A structural entity diagram showing an X-ray inspection device equipped with a compressor 100 and a compression rod of the compressor 100 when rotating according to an exemplary embodiment; Figure 5 FIG. 1 is a schematic diagram showing an X-ray inspection apparatus equipped with a compressor 100 and a compression rod of the compressor 100 when folded according to an exemplary embodiment.

[0067] like Figure 1 ,3 As shown in Figure 5, according to some embodiments of the compressor 100, the second sensor 1013 is configured to feed the clutch 107 with the rotational position information of the compression rod 102 by sensing the first sensing position 1074 and the second sensing position 1075 set on the clutch 107. The clutch 107 can rotate along with the compression rod 102, and the corresponding rotational position of the compression rod 102 is determined by determining the rotational position of the clutch 107. The clutch 107 is triggered to be in a disengaged state according to the fed rotational position information, that is, the clutch 107 moves to the first sensing position 1074 or the second sensing position 1075 and is sensed by the second sensor 1013, which means that the compression rod 102 rotates to be limited at the first limiting hole 1011 or the second limiting hole 1012 to form a specific angle or position with the base 101, and controls whether the latch 109 cooperates with the first limiting hole 1011 or the second limiting hole 1012 to limit, so as to achieve the limitation of the compression rod 102 and the base 101 at another position after the movement. Here, the second sensor 1013 may be a photoelectric switch, and openings may be set on the first sensing position 1074 and the second sensing position 1075, and the first sensing position 1074 and the second sensing position 1075 may be opened at the part of the clutch 107 opposite to the pressure rod 102, such as the second half clutch 1072. The second sensor 1013 may be set on the base 101, and may sense the rotation position information of the clutch 107 by facing or directly facing the first sensing position 1074 and / or the second sensing position 1075 through photoelectric sensing. Figure 1 As shown, taking the process of the compression rod 102 rotating from the horizontally extended position to the vertical position for folding as an example, when the compression rod 102 and the base 101 are horizontally extended, the second sensor 1013 senses the first sensing position 1074, the clutch 107 is triggered to be attracted, and one end of the latch 109 is disengaged from the first limiting hole 1011, and the compression rod 102 can be driven by the first motor 103 to rotate, and the clutch 107 or the second half clutch 1072 rotates counterclockwise with the compression rod 102, for example. Figure 3 , 5The second sensor 1013 shown only senses the area between the first sensing position 1074 and the second sensing position 1075, until the second sensor 1013 senses the second sensing position 1075, the compression rod 102 has rotated to a position perpendicular to the base 101 or a position with a smaller angle, and the clutch 107 is triggered to be in a separated state again according to the fed rotation position information, so that the latch 109 moves to cooperate with the second limiting hole 1012 for limiting. Here, the process of the compression rod 102 and the base 101 being in a vertical or folded position to a horizontally extended position is not described in detail. In addition, it is easy to understand that the first motor 103 can output forward and reverse drives, so that the compression rod 102 can reset between, for example, a position where the compression rod 102 is perpendicular to the base 101 and a position where it extends in a horizontal direction.

[0068] According to some embodiments of the compressor 100, specifically, the first sensor is configured to feed horizontal position information of the compressor 100 to the clutch 107, so that the clutch 107 is triggered to be in an engaged state according to the fed horizontal position information, and the compressor 100 moves along a lifting rod 20 driven by the first motor 103, and when the clutch 107 is triggered to be in an engaged state according to specific horizontal position information fed by the first sensor, the compression rod 102 rotates under the drive of the first motor 103. The second sensor 1013 is configured to sense that the clutch 107 moves to the first sensing position 1074 or the second sensing position 1075, and the clutch 107 is further configured to be triggered to be in a disengaged state when the clutch 107 moves to the first sensing position 1074 or the second sensing position 1075 sensed by the second sensor 1013, and at this time, the pin 109 moves to cooperate with the first limiting hole 1011 or the second limiting hole 1012 to be limited to the base 101 under the action of the clutch 107 being triggered to be in a disengaged state. Here, the compressor 100 can be driven by the first motor 103 to move along the lifting rod 20 and to drive the compression rod 102 to rotate, or can be driven by different motors respectively, which is not limited in this embodiment. The logical priority relationship set between the second sensor 1013 and the first sensor can be implemented by programming a controller, which is not described in detail in this embodiment.

[0069] According to some embodiments of the compressor 100, in order to enable the first motor 103 to drive the compression rod 102 to move or rotate through the transmission device, and to enable the clutch 107 to further move with the compression rod 102, the transmission device includes a first pulley 104 installed on the base 101, and a synchronous belt 105 for transmitting the first motor 103 to drive the first pulley 104 to move. The first pulley 104 is connected to the compression rod 102 through a hinge shaft 108, so that the first motor 103 can drive the compression rod 102 to move when driving the first pulley 104 to move, and the clutch 107 can be connected to the compression rod 102 through the hinge shaft 108 to rotate synchronously with the compression rod 102.

[0070] According to some embodiments of the compressor 100, the first motor 103 is driven by the output of the second pulley 106, the synchronous belt 105 is installed between the first pulley 104 and the second pulley 106 to drive the first pulley 104 to rotate, and at least one tensioning wheel 1051 is provided, so that the synchronous belt 105 is arranged between the first pulley 104 and the second pulley 106 through the tensioning wheel 1051 to guide the synchronous belt 105, and the tensioning wheel 1051 can provide tension for the synchronous belt 105.

[0071] like Figure 1 , 3 As shown in Figure 5, another aspect of the present disclosure further provides an X-ray inspection device 10, including: a lifting rod 20; an X-ray camera 30; and a compressor 100 as before, which is installed on the lifting rod 20 and guides the compressor 100 along the lifting rod 20 to adjust the horizontal position of the compressor 100, wherein when the compression rod 102 of the compressor 100 extends horizontally along the base 101 of the compressor 100, the compression rod 102 is located in the field of view of the X-ray camera 30 and can apply compression force to the patient's organ part, and the compression rod 102 is driven by the first motor 103 to adjust the angle between it and the base 101 until the compression rod 102 leaves the field of view.

[0072] According to some embodiments of the X-ray inspection device 10, a height sensing mark 201 is set on the lifting rod 20, and the first sensor is configured to feed the clutch 107 with the movement direction of the compressor 100 passing through the height sensing mark 201, for example, the movement direction is determined by the rise or fall along the lifting rod 20 corresponding to the positive and negative drive output by the first motor 103, so as to trigger the clutch 107 to be in the engaged state. When the compressor 100 passes through the height sensing mark 201 from top to bottom, for example, the compressor 100 passes through the height sensing mark 201 from top to bottom under the drive of the first motor 103, the clutch 107 is triggered to be in the engaged state, and the first motor 103 drives the compression rod 102 to rotate from the initial position to extend horizontally along the base 101 or to form an angle of 180 degrees, and the clutch 107 is configured so that when the second sensor 1013 senses that the compression rod 102 and the base 101 are horizontally extended, for example, the aforementioned second sensor 1013 senses that the clutch 107 rotates to the opening of the first sensing position 1074, The clutch 107 is triggered to be in a disengaged state, and the latch 109 can cooperate with the first limiting hole 1011 to limit the compression rod 102 to the base 101. At this time, the output of the first motor 103 to the compression rod 102 is idling, and the compressor 100 is kept moving along the lifting rod 20 to provide an external force to compress the patient's organs. When the compressor 100 passes the height sensing mark 201 from bottom to top, for example, under the reverse drive of the first motor 103, the compressor 100 passes the height sensing mark from bottom to top. Position 201, the clutch 107 is triggered to be in the engaged state, the first motor 103 drives the compression rod 102 to rotate from the initial position to be perpendicular to the base 101 for folding, and the clutch is configured so that when the second sensor 1013 senses that the compression rod 102 is perpendicular to the base 101 for folding, the clutch 107 is triggered to be in the separated state, the latch 109 can cooperate with the second limiting hole 1012 to limit, the compression rod 102 and the base 101 are limited, and the compression rod 102 leaves the field of view of the X-ray camera 30. Here, the first sensor can be a photoelectric switch, and the height sensing mark position 201 can be achieved by opening a through hole at a specific height position of the lifting rod 20. Here, the logical priority relationship set between the second sensor 1013 and the first sensor can be realized by programming a controller, and this embodiment will not be repeated. In addition, it is easy to understand that the first motor 103 can output positive and negative drives, so that the compression rod 102 can reset between, for example, a position where the compression rod 102 is perpendicular to the base 101 and a position extending in the horizontal direction. It should be noted that how the motor 103 starts the forward or reverse output to control the movement direction of the compressor 100 on the lifting rod 20 can be triggered by the external force of the user or set by command, etc., which will not be elaborated in this embodiment.
