Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and specifically relates to an all-round CT scanning device. Background Art

[0002] Currently, the common CT scanning devices usually adopt a fixed-plane scanning method. The patient lies flat on a non-tilting bed board and enters the scanning area by linear movement. 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 requirements. 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 fixed-plane scanning. 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 lack of diagnostic information. This forms the so-called scanning blind area, affecting the comprehensiveness and accuracy of medical diagnosis. Summary of the Invention

[0008] Preferably, an inclination angle control beam is fixed to the middle of the bottom of the lifting wing, and a counterweight block is embedded and installed inside one end of the inclination angle control beam in a manner convenient for disassembly.

[0009] Preferably, two symmetrically arranged inclination angle control swing plates are rotatably installed at one end of the inclination angle control beam away from the counterweight block.

Specific embodiments

[0021] The following combines the attached Figures 1-6 , and further illustrates the technical solution of the present invention through specific embodiments.

[0022] The present invention provides an all-round CT scanning device, including a driving pool 101. Inside the driving pool 101, a driving part enables the fluid to flow stably. And two stacked lifting wings 111 are arranged inside the driving pool 101. There is a gap between the two lifting wings 111. And both of the two lifting wings 111 are fixed at the bottom end of a support swing beam 107. A support tabletop 105 is fixed at the top of the support swing beam 107. A support overhead frame 123 is fixed on the support tabletop 105. A lying board 125 is slidably installed on the support overhead frame 123. The lying board 125 is driven by an adjusting transmission belt 124 arranged on the support overhead frame 123 to control the position of the lying board 125 on the support overhead frame 123. A stable auxiliary sliding frame 102 is fixedly connected to the driving pool 101. In the middle of the inner wall of the stable auxiliary sliding frame 102, an inclination angle pin shaft 113 is fixed. A sliding groove 108 is formed in the middle of the support swing beam 107. The sliding groove 108 is slidably arranged with the inclination angle pin shaft 113.

[0023] Two symmetrically arranged stable support plates 109 are fixedly installed on the lower surface of the support tabletop 105. Two parallel stable support sliding rods 117 are slidably installed at the bottom of the stable support plates 109. At one end of each of the two stable support sliding rods 117, a support sliding rod limiting ring 118 for limiting the displacement distance of the stable support sliding rod 117 is fixedly arranged. The other ends of the two stable support sliding rods 117 are fixedly matched with a roller support strip 120. Two support top springs 119 are fixed between the opposite surfaces of the stable support plates 109 and the roller support strip 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 strip 120. Two rollers 122 are also rotatably installed at both ends of the roller support strip 120. The rollers 122 and the rolling balls 121 are in rolling cooperation with the inner wall of the stable auxiliary sliding frame 102. A limiting piece 106 for limiting the displacement range of the rolling balls 121 and the rollers 122 is fixed at the top of the stable auxiliary sliding frame 102. The limiting piece 106 is in contact and cooperation with the support tabletop 105. In the middle of the bottom of the lifting wing 111, an inclination angle control beam 110 is fixed. At one end of the inclination angle control beam 110, a counterweight 112 is embedded and installed in a detachable manner. At the end of the inclination angle control beam 110 away from the counterweight 112, two symmetrically arranged inclination angle control swing plates 114 are rotatably installed. An inclination angle control swing arm 115 is fixed on each of the two inclination angle control swing plates 114. An inclination angle control electric cylinder 116 is also movably installed on the inclination angle control beam 110. The end of the telescopic rod of the inclination angle control electric cylinder 116 is movably connected to the end of the two inclination angle control swing arms 115 away from the inclination angle control swing plates 114. The end of the telescopic cylinder of the inclination angle control electric cylinder 116 is movably connected to the inclination angle control beam 110.

[0024] On both sides of the drive pool 101, two drive parts are symmetrically arranged. The two ends of each drive part are connected to the inside of the drive pool 101 through a communication nozzle 129. The drive part includes a fluid drive pipe 103. A drive paddle 104 is rotatably installed inside the fluid drive pipe 103. A flow velocity sensor is arranged inside the fluid drive pipe 103 to monitor the flow velocity of the fluid inside the drive pool 101. The drive pool 101 is arranged below the floor surface 126. The floor surface 126 is fixed on the protective shell 127. The drive part is arranged inside the protective shell 127. The protective shell 127 is buried under the floor so that the floor surface 126 is 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. 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 all-round CT scanning device disclosed by the present invention is as follows: Start the driving paddle 104. When the driving paddle 104 rotates, it will generate a stable and high-speed fluid inside the fluid driving tube 103. The fluid medium flows back into the inside of the fluid driving tube 103 after passing through the driving pool 101, and then is accelerated by the driving paddle 104 again. The flow velocity sensor provided inside the fluid driving tube 103 monitors the flow of the fluid medium in real time. The rotation speed of the driving paddle 104 is adjusted in real time based on the flow velocity to ensure the accuracy of the flow velocity of the fluid medium inside the driving pool 101. When the fluid passes through the lifting wing 111, it will change the pressure difference between the upper and lower surfaces of the lifting wing 111, making the pressure on the lower surface of the lifting wing 111 greater than that on the upper surface. Thus, the support table 105 is lifted upward by the support swing beam 107. At this time, the support overhead frame 123 and the lying board 125 on the support table 105 will also move accordingly (initially, the height of the lying board 125 is slightly lower, which is convenient for the user to climb onto the lying board 125). The patient lying on the lying board 125 is moved into the CT scanner 128 for scanning by adjusting the transmission belt 124. During the scanning process, the relative position between the lying board 125 and the CT scanner 128 is controlled by adjusting the transmission belt 124, so as to control the position of the patient relative to the CT scanner 128 and achieve scanning at different positions. During this process, since the CT scanner 128 always scans perpendicular to the height direction of the patient's body, there will inevitably be scanning blind spots. Therefore, the patient's body needs to be tilted to obtain more scanning data in different directions. Specifically, by controlling the telescopic movement of the telescopic rod of the inclination angle control electric cylinder 116, the inclination angle control swing arm 115 is driven to swing on the inclination angle control beam 110, thereby driving the swing of the inclination angle control swing plate 114. Initially, the inclination angle control swing plate 114 is in a horizontal state. When the fluid passes through the inclination angle control swing plate 114, there is no pressure difference between the upper and lower surfaces of the inclination angle control swing plate 114. When the inclination angle control swing plate 114 tilts, a pressure difference will occur between the upper and lower surfaces of the inclination angle control swing plate 114. The magnitude of the pressure difference depends on the tilt angle of the inclination angle control swing plate 114. Therefore, by controlling the telescopic amount of the telescopic rod of the inclination angle control electric cylinder 116, the pressure difference between the upper and lower surfaces of the inclination angle control swing plate 114 can be controlled. At the same time, the swing direction of the inclination angle control swing plate 114 can also determine the direction of the pressure difference. That is to say, the direction of the force on the inclination angle control swing plate 114 can also be controlled. When there is a pressure difference between the upper and lower surfaces of the inclination angle control swing plate 114, the force on the inclination angle control swing plate 114 will drive the inclination angle control beam 110 to swing. The swing of the inclination angle control beam 110 will drive the support table 105 to swing through the lifting wing 111 and the support swing beam 107. The swing of the support table 105 will drive the swing of the support 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 tabletop 105, the stable support plate 109 will move together with the support tabletop 105. Therefore, the stable support sliding rod 117 on the stable support plate 109, the roller support strip 120 on the stable support sliding rod 117, the rolling balls 121 and the rollers 122 on the roller support strip 120 will also move together. At this time, the rolling balls 121 and the rollers 122 will roll relative to the inner wall of the stable auxiliary sliding frame 102, and the stable support sliding rod 117 will slide relative to the stable support plate 109, and the support top spring 119 will deform, so as to provide a stable supporting force for the support tabletop 105. At the same time, relative sliding will also occur between the sliding groove 108 and the inclination angle pin shaft 113. A sliding resistor is arranged between the inclination angle pin shaft 113 and the sliding groove 108, so that a closed circuit is formed between the inclination angle pin shaft 113 and the sliding groove 108. By monitoring the resistance value in the circuit, the relative position of the inclination angle pin shaft 113 on the sliding groove 108 can be judged, so as to judge the height information of the middle position of the support tabletop 105. This is because when the patient lies on the lying board 125, it will cause the weight of the support tabletop 105 to increase or decrease. Therefore, it is necessary to provide a sufficient pressure difference between the upper and lower surfaces of the lifting wing 111 to support, so as to ensure that the support tabletop 105 has enough height to tilt. The tilting angle of the support tabletop 105 is synchronized with the tilting angle of the inclination angle control beam 110. Therefore, the inclination angle sensor arranged inside the inclination angle control beam 110 can monitor the inclination angle of the support tabletop 105 and the patient on the lying board 125. This inclination angle data is used to control the telescopic amount of the telescopic rod of the inclination angle control electric cylinder 116, so as to control the swinging angle of the inclination angle control swinging plate 114, realize closed-loop control, and ensure the accuracy and stability of the tilting angle of the lying board 125.
