Description

Technical Field

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

[0002] Traditional X-ray imaging equipment has many limitations in terms of shielding and adjustment. The general equipment shielding device mainly relies on the patient wearing a lead suit for protection. However, the weight of the lead suit is very large, usually between 5 and 10 kilograms, which is a considerable burden for weak, elderly or children. The heavy weight of the lead suit may cause the patient to feel uncomfortable during the examination, and even affect normal breathing and heart rate, increasing the risk of the examination.

[0003] In addition, the size and shape of lead suits are usually fixed and cannot adapt to patients of different body shapes and heights. For patients who are larger or smaller, the lead suit may not be able to fully cover the parts that need to be shielded, causing non-examination areas to still be exposed to radiation, increasing unnecessary radiation risks and radiation doses. At the same time, lead suits that are too large or too small will affect the patient's comfort, may cause tension and anxiety, and affect the examination results.

[0004] Since the lead suit cannot be flexibly adjusted according to the patient's specific situation, medical staff will also face difficulties during operation. For example, when taking X-rays of specific parts, the position or angle of the lead suit may need to be adjusted, but the rigidity and weight of the lead suit make the adjustment process cumbersome and time-consuming. This not only reduces the efficiency of the examination, but may also lead to repeated exposure, further increasing the patient's radiation dose. Summary of the invention

[0028] A foot pedal 106 is provided below the middle of the X-ray detector 132 and the lead plate 152. The foot pedal 106 is fixed to the top of a foot pedal support column 107. The foot pedal support column 107 is fixed to the base 103. A supporting and limiting circular wall 104 is fixed to the base 103. A supporting and limiting circular wall 104 is rotatably mounted on the inner wall of the supporting and limiting circular wall 104. A supporting rotating disk 109, an end driving gear ring 110 and an intermediate driving gear ring 111 are rotatably mounted on the inner wall of the supporting and limiting circular wall 104. 11 cannot support axial displacement of the circular wall 104; two symmetrically arranged grooves are opened at the circumference of the supporting rotating disk 109, and the grooves are composed of an extrusion inclined surface 120, a pushing surface 124 and a supporting surface 125, wherein an extrusion column 122 is provided for contact and friction between the extrusion inclined surface 120 and the supporting circular wall 104, and a lever pin 123 is provided on the side of the extrusion column 122 facing the pushing surface 124, and the extrusion column 122 and the supporting surface 125 are elastically connected by an elastic rubber pad 121. All the lever pins 123 are fixed on the end driving gear ring 110, wherein the supporting rotating disk 109 is rotatably sleeved on the pedal supporting column 107, the circumferential surface of the pedal supporting column 107 is located below the supporting rotating disk 109 and is rotatably sleeved with a central driving gear 119, a barrel shaft 118 is coaxially fixed on the central driving gear 119, the barrel shaft 118 is rotatably sleeved on the pedal supporting column 107, the central driving gear 119 and the end driving gear ring 110 are meshed and transmitted through a planetary speed regulating gear 116, wherein the planetary speed regulating gear 116 is rotatably mounted on a planetary speed regulating gear bracket 117, and the planetary speed regulating gear bracket 117 is fixed on the intermediate driving gear ring 111; a central driving gear 119 is coaxially fixed on the barrel shaft 118 A first driving motor 108 and a second driving motor 112 are fixed on the base 103, wherein a first driving gear 114 and a second driving gear 113 are respectively fixed on the output shafts of the first driving motor 108 and the second driving motor 112, the first driving gear 114 is meshed with the intermediate driving gear ring 111 for transmission, and the second driving gear 113 is meshed with the center driven gear 115 for transmission, and a dust cover 105 is covered on the top of the supporting and limiting circular wall 104 and the supporting rotating disk 109, the dust cover 105 is rotatably matched with the supporting and limiting circular wall 104, the dust cover 105 is relatively stationary with the supporting rotating disk 109, and the dust cover 105 is rotatably matched with the pedal support column 107.

[0029] The base 103 is fixed inside the embedded box body 101. A circular opening 102 is formed on the top of the embedded box body 101. A bridge plate 150 is fixedly provided on the edge of the circular opening 102 in a manner that is easy to disassemble.

[0030] The bridge plate 150 is set between the foot pedal 106 and the circular opening 102 (for example, a hinge is set at the connection between the bridge plate 150 and the circular opening 102), and the user walks on the foot pedal 106 so that his body is located between the X-ray detector 132 and the lead plate 152. The X-ray emitter 151 emits X-rays, which then pass through the human body and are developed and received on the X-ray detector 132. In order to reduce the excess X-ray radiation, two freely movable lead plates 152 are set to block it, so that the X-rays can only pass through the gap between the two lead plates 152. The position of the two lead plates 152 can be adjusted by moving the corresponding top lead plate support The support frame 137 and the bottom lead plate support frame 138 are adjusted. Specifically, the center screw 140 is controlled to rotate, and the center screw 140 will drive the top lead plate support frame 137 to move linearly on the fine-tuning longitudinal moving beam 139, thereby adjusting the height of the lead plate 152 on the top lead plate support frame 137. The sleeve shaft screw 141 is controlled to rotate, and the sleeve shaft screw 141 drives the bottom lead plate support frame 138 to move linearly on the fine-tuning longitudinal moving beam 139, thereby adjusting the height of the lead plate 152 on the bottom lead plate support frame 138. By adjusting the height of the two lead plates 152, the gap between the two lead plates 152 and the position of the gap can be adjusted. To control the rotation of the central lead screw 140, it is necessary to start the lead plate displacement drive motor 146. The output shaft of the lead plate displacement drive motor 146 drives the gear column 145 to rotate, and the gear column 145 drives the central rotating toggle gear 144 to rotate. At this time, the electromagnet inside the top rotating disk 142 is started, so that the central rotating toggle gear 144 and the top rotating disk 142 attract each other, and then the central rotating toggle gear 144 drives the top rotating disk 142 to rotate, and the top rotating disk 142 drives the central lead screw 140 to rotate. If the sleeve shaft lead screw 1 41 rotates, it is only necessary to control the electromagnet inside the bottom rotating disk 143 to be energized (at the same time, the electromagnet inside the top rotating disk 142 needs to be de-energized), and then attract the central rotating toggle gear 144 to move toward the bottom rotating disk 143, and then the central rotating toggle gear 144 drives the bottom rotating disk 143 to rotate, thereby driving the sleeve shaft screw 141 to rotate. It should be noted that the central rotating toggle gear 144 and the bottom rotating disk 143 and the top rotating disk 142 are all provided with toothed or rough friction surfaces that can mesh with each other.

[0031] According to the volume of the object to be irradiated, the distance between the lead plate 152 and the X-ray detector 132 is adjusted, specifically by controlling two fine-tuning motors 135, the fine-tuning motors 135 drive the two fine-tuning screws 136 to rotate, and the two fine-tuning screws 136 drive the fine-tuning longitudinal moving beam 139 to move along the axial direction, and then the sleeve screw 141 and the center screw 140 can drive the bottom lead plate support frame 138 and the top lead plate support frame 137 to move, thereby driving the two lead plates 152 to move. If different positions need to be irradiated, it is only necessary to control the guide drive motor 129, the output shaft of the guide drive motor 129 drives the guide drive screw 128 to rotate, and the guide drive screw 128 drives the adjustment cross frame 130 to move vertically on the guide slide bar 127, thereby adjusting the irradiation position of the X-ray emitter 151. If the irradiation angle needs to be adjusted, it is necessary to control the first drive motor 108 and / or the second drive motor 112 (it should be noted that a worm gear one-way transmission mechanism is provided between the output shaft of the first drive motor 108 and the first driving gear 114, and a worm gear one-way transmission mechanism is provided between the output shaft of the second drive motor 112 and the second driving gear 113). The first driving motor 108 is started separately, and the output shaft of the first driving motor 108 drives the first driving gear 114 to rotate, and the first driving gear 114 drives the intermediate driving gear ring 111 to rotate, and the intermediate driving gear ring 111 drives the planetary speed regulating gear bracket 117 to rotate, and the planetary speed regulating gear bracket 117 drives the planetary speed regulating gear 116 to revolve and rotate (wherein the central driven gear 115, the cylindrical shaft 118, and the central driving gear 119 are all rotated in coordination with the planetary speed regulating gear bracket 117 to play a supporting role), wherein the self-rotation is due to the central driving gear 119 being unable to rotate, and then the planetary speed regulating gear 116 in the revolving and rotating state will drive the end driving gear ring 110 to rotate, and the rotation of the end driving gear ring 110 will drive all the lever pins 123 to rotate, and then the supporting rotating disk 109 will be driven to rotate, and at this time all the components installed on the supporting rotating disk 109 will rotate accordingly, so as to adjust the X-ray emitter 151 to irradiate at different angles of the human body.The second drive motor 112 is started separately, and the output shaft of the second drive motor 112 drives the second driving gear 113 to rotate, and the second driving gear 113 drives the central driven gear 115 to rotate, and the central driven gear 115 drives the central driving gear 119 to rotate, and the central driving gear 119 drives the terminal driving gear ring 110 to rotate through the planetary speed regulating gear 116. If the first drive motor 108 and the second drive motor 112 are started at the same time, the rotation speed and direction of the terminal driving gear ring 110 can be adjusted according to the corresponding rotation speed and rotation direction of the first drive motor 108 and the second drive motor 112, and then the rotation speed and direction of the supporting rotating disk 109 are adjusted. Since the lever pin 123 is set in the symmetrically set groove opened on the supporting rotating disk 109, the lever pin 123 can directly drive the supporting rotating disk 109 to rotate, and the supporting rotating disk 109 can be supported. When 109 is subjected to external force, in order to prevent the supporting rotating disk 109 from rotating (for example, the human body exerts force on the X-ray detector 132), if the supporting rotating disk 109 wants to rotate, it needs to drive the extrusion column 122 to rotate with it. However, no matter whether the extrusion column 122 rotates clockwise or counterclockwise, there will always be an extrusion column 122 that is subjected to the friction force of the supporting and limiting circular wall 104, and the direction is on the extrusion slope 120 toward the pushing surface 124 (because the two extrusion slopes 120 and the extrusion column 122 are symmetrically arranged), that is, it moves in the direction of reducing space, thereby increasing the extrusion force of the supporting and limiting circular wall 104 and the extrusion slope 120 on the extrusion column 122, and the friction force also increases, resulting in the supporting rotating disk 109 and the supporting and limiting circular wall 104 being unable to rotate relative to each other under the restriction of the extrusion column 122, thereby preventing the supporting rotating disk 109 from rotating. When the lever pin 123 rotates, it will move one of the stuck extrusion columns 122 on the extrusion slope 120 toward the support surface 125 (the elastic rubber pad 121 is compressed). At this time, the support and restriction circular wall 104 and the extrusion slope 120 will no longer squeeze the extrusion column 122, and the friction will disappear. Similarly, the friction force on the other extrusion column 122 is also toward the support surface 125, so the effect is the same. When the lever pin 123 actively drives the support rotating disk 109 to rotate, the support rotating disk 109 can rotate in the support and restriction circular wall 104, otherwise it cannot rotate. It should be noted that the embedded box body 101 is buried under the ground surface, so that the upper surface of the embedded box body 101 is flush with the ground surface.
