Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical testing technology, and in particular to a dual-suspension DR. Background Technology
[0002] Digital radiography (DR) is a direct X-ray imaging technique. Its principle is as follows: an X-ray tube assembly emits a certain dose of X-rays that pass through the human body. Because different tissues in the body absorb X-rays differently, the amount of X-rays remaining after passing through the body will vary. A flat-panel detector receives the X-rays after they have passed through the body and converts this difference in X-ray concentration into different electrical signals. These electrical signals are then recognized and converted by software to output the X-ray image we see.
[0003] Digital radiography (DR) is a widely used diagnostic method in clinical practice. Through several generations of technological advancements, it boasts advantages such as fast imaging speed, high image quality, low radiation dose, and rapid clinical diagnosis, making it widely applicable for X-ray examinations of various parts of the body. Common digital medical X-ray systems can be broadly categorized into single-suspension, flatbed, UC-arm, and mobile types. However, due to limitations in the usage environment and the equipment itself, these structural forms of DR systems cannot simultaneously meet the needs of multiple special patient positions requiring X-ray imaging in clinical settings.
[0004] Therefore, how to provide a dual-suspension DR that can simultaneously meet the needs of X-ray imaging in various special clinical positions is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

Therefore, they should not be construed as limitations of this utility model.
[0047] The purpose of this invention is to provide a dual-suspension DR that can simultaneously meet the needs of X-ray imaging in various special clinical positions.
[0048] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, the Z direction as the second direction, and the Y direction as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.
[0049] Please see Figures 1 to 3 To achieve the above objectives, this utility model provides a dual-suspension DR, including a bed 110 assembly and a detection assembly.
[0050] The bed frame 110 assembly includes a bed frame 110 and a lifting mechanism 120 capable of driving the bed frame 110 to move vertically. The lifting mechanism 120 is connected to one end of the bed frame 110 so that the other end of the bed frame 110 is suspended in the air. The bed frame 110 is a horizontally arranged plate structure. The distance between the bed frame 110 and the bottom surface can be increased by raising the lifting mechanism 120, and the distance between the bed frame 110 and the bottom surface can be decreased by lowering the lifting mechanism 120.
[0051] The detection assembly includes a fixed frame 200 located above the bed 110, a movable component movably connected to the fixed frame 200, and a receiver assembly and a transmitter 530 assembly connected to the movable component. The movable component is capable of moving the receiver assembly and the transmitter 530 assembly to both sides of the bed 110 in a first direction and / or both sides in a second direction.
[0052] It should be noted that in this embodiment, the first direction is the width direction of the bed body 110, the second direction is the vertical direction, and the third direction is the length direction of the bed body 110. Specifically, the receiver assembly and the transmitter assembly are moved to both sides of the bed body 110 in the first direction, that is, the receiver assembly and the transmitter assembly are moved to both sides of the bed body 110 in the width direction. The receiver assembly and the transmitter assembly are moved to both sides of the bed body 110 in the second direction, that is, the receiver assembly and the transmitter assembly are located below and above the bed body 110.
[0053] The lifting mechanism 120 is connected to one end of the bed 110, so that the other end of the bed 110 is suspended in the air, thereby increasing the space for movement of the receiver assembly and the transmitter assembly. When the receiver assembly and the transmitter assembly move to the two sides of the bed 110 in the first direction, lateral radiography can be realized. When the receiver assembly and the transmitter assembly move to the two sides of the bed 110 in the second direction, supine long bone splicing radiography can be realized. There is a space for movement around the bed 110, and the moving component can drive the receiver assembly and the transmitter assembly to move to various positions, which can simultaneously meet the needs of X-ray radiography in various special positions in clinical practice.
[0054] In this embodiment, the movable component includes a connecting frame 310, a connecting frame 320, two hanger heads 330, and two telescopic rods 340. The connecting frame 310 is connected to the fixed frame 200 and can move relative to the fixed frame 200 along a first direction. The connecting frame 320 is disposed at the bottom of the connecting frame 310 and can move relative to the connecting frame 310 along the length direction of the bed 110. The two hanger heads 330 are movably connected to the bottom of the connecting frame 320 through a translation mechanism, which can drive the two hanger heads 330 to move away from or towards each other synchronously. The two telescopic rods 340 can move along a second direction and are connected to the bottom of the corresponding hanger head 330. A receiver assembly is connected to the bottom of one telescopic rod 340, and a transmitter assembly is connected to the bottom of the other telescopic rod 340.
[0055] The moving component also includes a cylinder assembly disposed between the fixed frame 200 and the connecting frame 310. The cylinder includes a cylinder body and a piston rod connected to each other. The cylinder body is connected to the fixed frame 200, and the end of the piston rod away from the cylinder body is connected to the connecting frame 310. The fixed frame 200 is provided with a slide rail extending in a first direction, and the connecting frame 310 is provided with a slider adapted to the slide rail. The cylinder assembly can drive the slider to move along the extension direction of the slide rail. The slide rail of the fixed frame 200 is also provided with a limiting device. The limiting device can abut against the slider to limit the movement of the connecting frame 310. The limiting device can be a mechanical limiting device and / or an electrical limiting device to avoid excessive movement.
[0056] The connecting frame 320 is connected to a first power source, which can be an electric motor. The electric motor can drive the connecting frame 320 to move relative to the connecting frame 310 in a third direction, thereby realizing the movement of the connecting frame 320 relative to the fixed frame 200 in the first direction and the third direction.
[0057] Two hanger heads 330 are movably connected to the bottom of the connecting frame 320 via a translation mechanism. The translation mechanism includes a lead screw, a first nut, a second nut, and a guide shaft. The lead screw is rotatably connected to the connecting frame 320 and has a first threaded section and a second threaded section with opposite thread directions. The first nut is threaded to the first threaded section and connected to one hanger head 330. The second nut is threaded to the second threaded section and connected to the other hanger head 330. The guide shaft is located at the bottom of the connecting frame 320 and passes through the two hanger heads 330 so that the two hanger heads 330 can move along the extension direction of the lead screw.
[0058] The lead screw is connected to a second power source, which can also be a motor. The forward rotation of the motor drives the lead screw to rotate around its own axis. Through the first and second threaded sections with opposite directions, the first and second nuts cause the two hanger heads 330 to move closer to each other. The reverse rotation of the motor drives the lead screw to rotate around its own axis. Through the first and second threaded sections with opposite directions, the first and second nuts cause the two hanger heads 330 to move away from each other. In this way, the two hanger heads 330 can be moved away or closer synchronously through the same lead screw, thereby improving the efficiency of adjusting the distance between the two hanger heads 330.
[0059] In some embodiments, two sets of translation mechanisms can also be used to control the two hanger heads 330 respectively, which can also achieve the mutual separation and proximity of the two hanger heads 330. The translation mechanism can also be set as a slide rail pulley mechanism or a cylinder assembly, etc., as needed. It will not be described in detail here, as long as the above purpose can be achieved.
[0060] In this embodiment, the receiver assembly includes a first mounting base 410, a first rotating shaft 420, and a detector 430. The first mounting base 410 is connected to the corresponding telescopic rod 340 and can rotate about the axis of the telescopic rod 340. The first rotating shaft 420 is horizontally connected to the first mounting base 410. The detector 430 is connected to the end of the first rotating shaft 420 away from the first mounting base 410, and the detector 430 can rotate about the axis of the first rotating shaft 420.
[0061] The first mounting base 410 is equipped with a third power source and a fourth power source. The third power source is used to drive the first mounting base 410 to rotate around the axis of the telescopic rod 340. Figure 1 The fourth power source is used to control the horizontally set first rotating shaft 420 to drive the detector 430 to rotate around the axis of the first rotating shaft 420 (rotation in the β direction). Figure 1 Rotation in the α direction).
[0062] The transmitter assembly includes a second mounting base 510, a second rotating shaft, and a transmitter 530. The second mounting base 510 is connected to a corresponding telescopic rod 340 and is rotatable about the axis of the telescopic rod 340. The second rotating shaft is horizontally connected to the second mounting base 510. The transmitter 530 is connected to the two ends of the second rotating shaft away from the second mounting base 510 and is rotatable about the axis of the second rotating shaft.
[0063] The second mounting base 510 is equipped with a fifth power source and a sixth power source. The fifth power source is used to drive the second mounting base 510 to rotate around the axis of the telescopic rod 340. Figure 1 The sixth power source is used to control the horizontally set second rotating shaft to drive the detector 430 to rotate around the axis of the second rotating shaft (rotation in the β direction). Figure 1Rotation in the α direction).
[0064] In this way, the detector 430 and the transmitter 530 can move in five directions: X, Y, Z, α, and β.
[0065] When it is necessary to perform detection on both sides of the bed 110 in the first direction, the lead screw controls the distance between the two hanger heads 330 to a preset value, and the piston rod drives the hanger heads 330 to move above the bed 110 so that the projection of the bottom of the telescopic rod 340 on the ground is located on both sides of the width direction of the bed 110. The rotation of the first rotating shaft 420 and the second rotating shaft along the α direction, and the rotation of the first mounting base 410 and the second mounting base 510 along the β direction, make the detector 430 and the transmitter 530 correspond. Control the telescopic rod 340 to move down so that the detector 430 and the transmitter 530 are located on both sides of the bed 110. Then, the connecting frame 320 moves to the designated position along the third direction to complete the lateral position photography. The above steps can be adjusted in a certain order to achieve the above purpose.
[0066] When it is necessary to perform detection on both sides of the bed 110 in the second direction, the telescopic rod 340 moves down to different degrees so that the height of the detector 430 is lower than that of the bed 110 and the height of the transmitter 530 is higher than that of the bed 110. By rotating the first rotating shaft 420 and the second rotating shaft in the α direction, and by rotating the first mounting base 410 and the second mounting base 510 in the β direction, the detector 430 and the transmitter 530 are both in a horizontal state. By controlling the screw to reduce the distance between the two hanger heads 330, the detector 430 and the transmitter 530 are aligned vertically. The cylinder assembly is controlled to move the detector 430 and the transmitter 530 to the lower and upper sides of the bed 110, respectively. Then, by moving the connecting frame 320 in the third direction to the designated position, the supine long bone splicing photography can be completed.
[0067] In addition, the control module signal can be connected to the first power source, second power source, third power source, fourth power source, fifth power source, sixth power source, etc., to achieve precise control of the above actions through data or mode input.
[0068] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0069] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0070] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
