Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to an omnidirectional CT scanning device. Background Art

[0002] Current CT scanning equipment usually uses a fixed-plane scanning method. The patient lies flat on a bed that cannot be tilted and enters the scanning area by moving in a straight line. The limitation of this design is that the patient can only be examined in a fixed posture and cannot adjust the body position according to specific examination needs. Due to the complexity of the human body structure, some organs or tissues are located at special angles or positions, and it is difficult to obtain clear images only by scanning in a fixed plane. For example, for some lesions located deep in the body or blocked by other tissues, fixed-angle scanning may not be able to accurately capture them, resulting in the loss of diagnostic information. This forms the so-called scanning blind spot, which affects the comprehensiveness and accuracy of medical diagnosis. Summary of the invention

[0023] Two symmetrically arranged stable support plates 109 are fixedly installed on the lower surface of the support table 105. Two parallel stable support sliding rods 117 are slidably installed on the bottom of the stable support plate 109. A support sliding rod limit ring 118 for limiting the displacement distance of the stable support sliding rod 117 is fixedly installed at one end of the stable support sliding rod 117. The other ends of the two stable support sliding rods 117 are fixedly matched with the roller support bar 120. Two support top springs 119 are fixed between the opposite surfaces of the stable support plate 109 and the roller support bar 120. The two support top springs 119 are respectively arranged around the two stable support sliding rods 117; two rolling balls 121 are rotatably installed at both ends of the roller support bar 120, and rollers 122 are also rotatably installed at both ends of the roller support bar 120. The rollers 122 and the rolling balls 121 are rollingly matched with the inner wall of the stable auxiliary sliding frame 102. A limit plate 106 for limiting the displacement range of the rolling ball 121 and the roller 122 is fixed on the top of the stable auxiliary sliding frame 102, and the limit plate 106 contacts and cooperates with the support table 105. A tilt control beam 110 is fixed in the middle of the bottom of the lifting wing 111, and a counterweight 112 is embedded and installed in one end of the tilt control beam 110 in a convenient disassembly manner. Two symmetrically arranged tilt control swing plates 114 are rotatably installed on the end of the tilt control beam 110 away from the counterweight 112, and tilt control swing arms 115 are fixed on the two tilt control swing plates 114. A tilt control electric cylinder 116 is also movably installed on the tilt control beam 110, and the end of the telescopic rod of the tilt control electric cylinder 116 is movably connected to the end of the two tilt control swing arms 115 away from the tilt control swing plates 114, and the end of the telescopic tube of the tilt control electric cylinder 116 is movably connected to the tilt control beam 110.

[0024] Two driving parts are symmetrically arranged on both sides of the driving pool 101, and the two ends of each driving part are connected to the inside of the driving pool 101 through the connecting nozzle 129. The driving part includes a fluid driving pipe 103, and a driving blade 104 is rotatably installed inside the fluid driving pipe 103. A flow rate sensor is arranged inside the fluid driving pipe 103 to monitor the flow rate of the fluid inside the driving pool 101. The driving pool 101 is arranged below the floor surface 126, and the floor surface 126 is fixed on the protective shell 127. The driving part is arranged inside the protective shell 127, and the protective shell 127 is buried under the floor so that the floor surface 126 is arranged flush with the floor surface. A CT scanner 128 is fixed on the floor surface 126 so that the lying board 125 can pass through the CT scanner 128. An inclination sensor for monitoring the horizontal state is embedded inside the inclination control beam 110, and a distance sensor is arranged between the sliding groove 108 and the inclination pin shaft 113 to monitor the position of the inclination pin shaft 113 in the sliding groove 108.

[0025] The working principle of an omnidirectional CT scanning device disclosed in the present invention is as follows: starting the driving blade 104, the driving blade 104 rotates to generate a stable high-speed fluid inside the fluid driving tube 103, the fluid medium flows back into the fluid driving tube 103 after passing through the driving pool 101, and is then accelerated again by the driving blade 104, the flow rate sensor arranged inside the fluid driving tube 103 monitors the flow of the fluid medium in real time, and the rotation speed of the driving blade 104 is adjusted in real time based on the flow rate to ensure the accuracy of the flow rate of the fluid medium inside the driving pool 101. When the fluid passes through the lifting wing 111, the pressure difference between the upper and lower surfaces of the lifting wing 111 will be changed, so that the pressure on the lower surface of the lifting wing 111 is greater than the pressure on the upper surface, thereby lifting the support table 105 upward through the support swing beam 107, and at this time, the support overhead frame 123 and the lying board 125 on the support table 105 will also move with it (the height of the lying board 125 is slightly lower at the beginning, so that it is convenient for the user to climb onto the lying board 125), and the patient lying on the lying board 125 is moved to the CT scanner 128 for scanning by adjusting the transmission belt 124. During the scanning process, the relative position of the lying board 125 and the CT scanner 128 is controlled by adjusting the transmission belt 124, thereby controlling the position of the patient in the CT scanner 128, and realizing scanning at different positions. In this process, since the CT scanner 128 scans in a height direction perpendicular to the patient's body, it is inevitable that there will be a scanning blind spot, so it is necessary to tilt the patient's body to obtain scanning data in more directions. Specifically, by controlling the extension and retraction of the telescopic rod of the tilt control electric cylinder 116, the tilt control swing arm 115 is driven to swing on the tilt control beam 110, thereby driving the tilt control swing plate 114 to swing. At the beginning, the tilt control swing plate 114 is in a horizontal state, resulting in no pressure difference between the upper and lower surfaces of the tilt control swing plate 114 when the fluid passes through the tilt control swing plate 114. When the tilt control swing plate 114 tilts, a pressure difference will occur between the upper and lower surfaces of the tilt control swing plate 114. The size of the pressure difference depends on the size of the tilt angle of the tilt control swing plate 114. Therefore, by controlling the extension and retraction of the telescopic rod of the tilt control electric cylinder 116, The pressure difference between the upper and lower surfaces of the inclination control swing plate 114 can be controlled, and the swinging direction of the inclination control swing plate 114 can also determine the direction of the pressure difference. That is to say, the direction of the force applied to the inclination control swing plate 114 can also be controlled. When there is a pressure difference between the upper and lower surfaces of the inclination control swing plate 114, the force applied to the inclination control swing plate 114 will drive the inclination control beam 110 to swing. The swinging of the inclination control beam 110 will drive the supporting table 105 to swing through the lifting wing 111 and the supporting swing beam 107. The swinging of the supporting table 105 will drive the swinging of the supporting overhead frame 123 and the lying board 125, thereby changing the angle between the patient and the CT scanner 128.During the tilting process of the support table 105, the stable support plate 109 will move along with the support table 105, so the stable support sliding rod 117 on the stable support plate 109, the roller support bar 120 on the stable support sliding rod 117, and the rolling ball 121 and roller 122 on the roller support bar 120 will also move along. At this time, the rolling ball 121 and the roller 122 will roll relative to the inner wall of the stable auxiliary sliding frame 102, and the stable support sliding rod 117 and the stable support plate 109 will slide relative to each other, and the support top spring 119 will be deformed, thereby providing a stable supporting force for the support table 105. At the same time, the sliding groove 108 and the inclination pin 113 will also slide relative to each other. A sliding resistor is set between the inclination pin 113 and the sliding groove 108, so that a closed loop is formed between the inclination pin 113 and the sliding groove 108. By monitoring the resistance value in the loop, the relative position of the inclination pin 113 on the sliding groove 108 can be determined, thereby determining the height confidence of the middle position of the support table 105. This is because when the patient lies on the lying board 125, the weight of the support table 105 will increase or decrease. Therefore, the upper and lower surfaces of the lifting wing 111 need to provide sufficient pressure difference for support, thereby ensuring that the support table 105 has sufficient height to be tilted. The inclination angle of the support table 105 is synchronized with the inclination angle of the inclination control beam 110. Therefore, the inclination sensor arranged inside the inclination control beam 110 can monitor the inclination angle of the support table 105 and the patient on its lying board 125. The inclination angle data is used to control the extension and retraction amount of the telescopic rod of the inclination control electric cylinder 116, thereby controlling the swing angle of the inclination control swing plate 114, realizing closed-loop control, and ensuring the accuracy and stability of the inclination angle of the lying board 125.
