Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a novel large three-dimensional medical water tank for radiotherapy quality control testing. Background Technology

[0002] In clinical medicine, the 3D scanning tank is filled with a test liquid that simulates the internal tissues of the human body. During the debugging or quality control testing of radiotherapy equipment, the 3D scanning tank serves as an important radiotherapy device for collecting or verifying data under various irradiation field conditions.

[0003] Patent publication number CN220159058U discloses a compact three-dimensional scanning water tank, including a tank body, a detection liquid, a three-dimensional transmission mechanism, and a scanning ionization chamber; the three-dimensional transmission mechanism includes at least a plurality of lead screw assemblies for driving the scanning ionization chamber.

[0004] To address the issue that traditional 3D scanning water tank transmission devices occupy significant internal and external space, limiting their application, existing technologies employ lead screws for transmission. This reduces the space occupied by the transmission device within the detection liquid, increases the effective measurement volume of the scanning ionization chamber within the detection liquid, and thus reduces the contribution of the 3D transmission mechanism to scattered radiation during scanning. However, this approach still presents challenges: multiple complex transmission devices are used to move the detection probe; the transmission devices are located outside the 3D scanning water tank, leading to complex operation and maintenance procedures; and substances from the external environment can easily enter the 3D scanning water tank and mix with the liquid, affecting the detection results.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A novel large three-dimensional medical water tank for radiotherapy quality control testing includes a water tank, the interior of which is equipped with an adjustment mechanism.

[0007] The adjusting mechanism includes an annular groove and an annular rack. The annular groove and the annular rack are fixedly connected to the upper side of the inner cavity of the water tank. Slider 1 and slider 2 are slidably connected inside the annular groove. A connecting frame is fixedly connected to the bottom surface of one end of slider 1. Motor 1 is fixedly connected to the bottom surface of the connecting frame. A connecting rod is rotatably connected to the side of the output shaft of motor 1. Gear 1 is fixedly connected to one end of the output shaft of motor 1. Gear 1 meshes with the annular rack.

[0008] A further improvement of this utility model is that: a connecting column is fixedly connected to the bottom surface of one end of the slider two, one end of the connecting rod is rotatably connected to the connecting column, and a gear two is rotatably connected to one end of the connecting column, the gear two meshing with the annular rack.

[0010] A further improvement of this utility model is that: one end of the output shaft of the second motor passes through the top surface of the base plate and is fixedly connected to a lead screw, and one end of the lead screw is rotatably connected inside the bottom surface of the connecting plate.

[0011] A further improvement of this utility model is that a lifting plate is threadedly connected to the side of the lead screw, and the lifting plate is slidably connected to the slide rod.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This utility model provides a novel large three-dimensional medical water tank for radiotherapy quality control testing. It employs an adjusting mechanism, annular groove, annular rack, slider one, slider two, connecting frame, motor one, connecting rod, gear one, connecting column, gear two, connecting plate, slide rod, base plate, motor two, lead screw one, lifting plate, support plate, motor three, lead screw two, moving block, and detection probe. By activating motor one according to the three-dimensional coordinates of the detection point, it drives gear one to rotate. Gear one meshes with the annular rack, driving motor one to rotate. When motor one rotates, it drives slider one to slide in the annular groove via the connecting frame. Slider one, connected to the annular groove and connecting frame, supports motor one. Motor one is connected to the connecting column via the connecting rod. When motor one rotates, it drives slider two to rotate within the annular rack via the connecting rod and connecting column, driving gear two to mesh with the annular rack. Slider two, connected to the annular rack and connecting column, supports gear two.

The connecting rod rotates, connecting the connecting plate to rotate the connecting plate device, which in turn drives the lifting plate device to rotate. The lifting plate device, through the moving block, drives the detection probe to rotate, adjusting the coordinate position of the detection probe. When the connecting rod rotates to the specified angle, motor one is turned off. At this time, the angles formed by the connecting rod with the x-axis and y-axis are equal to the angles formed by the detection point with the x-axis and y-axis. Motor three is started, driving screw two to rotate. When screw two rotates, it drives the moving block and the detection probe to move, thus moving the detection probe to the x and y coordinates of the detection point. After the detection probe reaches the specified coordinates, motor two is started, driving screw one to rotate. Screw one connects to the lifting plate, driving the lifting plate to rise and fall. The sliding rod connects to the lifting plate to improve the stability of the lifting plate's rise and fall. When the lifting plate rises and falls, it drives the detection probe to rise and fall, thus moving the detection probe to the z-axis coordinate of the detection point. At this time, the three-dimensional coordinate position of the detection probe is the same as the three-dimensional coordinate position of the detection point, which facilitates the detection probe to detect the specified detection point and improves the adaptability of the device.

[0017] The present invention will be further described in detail below with reference to embodiments: Example 1 like Figure 1-4 As shown, this utility model provides a novel large three-dimensional medical water tank for radiotherapy quality control testing, including a water tank 1. An adjustment mechanism 2 is provided inside the water tank 1. The adjustment mechanism 2 includes an annular groove 201 and an annular rack 202. The annular groove 201 and the annular rack 202 are fixedly connected to the upper side of the inner cavity of the water tank 1. A slider 1 203 and a slider 204 are slidably connected inside the annular groove 201. A connecting frame 205 is fixedly connected to the bottom surface of one end of slider 1 203. A motor 206 is fixedly connected to the bottom surface of a slider 204. A connecting rod 207 is rotatably connected to the side of the output shaft of the motor 206. A gear 208 is fixedly connected to one end of the output shaft of the motor 206, and the gear 208 meshes with a ring rack 202. A connecting post 209 is fixedly connected to the bottom surface of one end of the slider 204. One end of the connecting rod 207 is rotatably connected to the connecting post 209. A gear 210 is rotatably connected to one end of the connecting post 209, and the gear 210 meshes with the ring rack 202. The connecting rod 207... A connecting plate 211 is fixedly connected to one side of the bottom surface of the device. A sliding rod 212 is fixedly connected to one side of the bottom surface of the connecting plate 211. A base plate 213 is fixedly connected to one end of the sliding rod 212. A motor 214 is fixedly connected to one side of the bottom surface of the base plate 213. One end of the output shaft of the motor 214 passes through the top surface of the base plate 213 and is fixedly connected to a lead screw 215. One end of the lead screw 215 is rotatably connected to the inside of the bottom surface of the connecting plate 211. A lifting plate 216 is threadedly connected to the side of the lead screw 215. 16 is slidably connected to slide rod 212. Support plates 217 are fixedly connected to both sides of lifting plate 216. Motor 3 218 is fixedly connected to the side of one support plate 217. One end of the output shaft of motor 3 218 passes through the side of support plate 217 and is fixedly connected to lead screw 219. One end of lead screw 219 is rotatably connected to the inside of the side of another support plate 217. Moving block 220 is threadedly connected to the side of lead screw 219. Detection probe 221 is fixedly installed inside moving block 220.

[0018] In this embodiment, the motor 206 is activated based on the three-dimensional coordinates of the detection point, driving the gear 208 to rotate. The gear 208 meshes with the annular rack 202, causing the motor 206 to rotate. When the motor 206 rotates, it drives the slider 203 to slide in the annular groove 201 via the connecting frame 205. The slider 203, connected to the annular groove 201 and the connecting frame 205, supports the motor 206. The motor 206 is connected to the connecting column 209 via the connecting rod 207. When the motor 206 rotates, it is connected to the connecting rod 207... The connecting column 209 drives the second slider 204 to rotate within the ring rack 202, which in turn drives the second gear 210 to mesh and rotate with the ring rack 202. The second slider 204, connected to the ring rack 202 and the connecting column 209, supports the second gear 210. When the first gear 208 and the second gear 210 mesh and rotate with the ring rack 202, they drive the connecting rod 207 to rotate via the first motor 206 and the connecting column 209. The connecting rod 207 is connected to the connecting plate 211, which drives the connecting plate 211 to rotate and, through the connecting plate 211, drives the lifting plate 216. The lifting plate 216 rotates, and the moving block 220 drives the detection probe 221 to rotate, adjusting the coordinate position of the detection probe 221. When the connecting rod 207 rotates to the specified angle, the motor 1 206 is turned off. At this time, the angle between the connecting rod 207 and the x-axis and y-axis is equal to the angle between the detection point and the x-axis and y-axis. The motor 3 218 is started, driving the lead screw 219 to rotate. When the lead screw 219 rotates, it drives the moving block 220 and the detection probe 221 to move, thereby moving the detection probe 221 to the x and y coordinates of the detection point. After head 221 reaches the designated coordinate, motor 214 is started to drive lead screw 215 to rotate. Lead screw 215 is connected to lifting plate 216 to drive lifting plate 216 to rise and fall. Slide rod 212 is connected to lifting plate 216 to improve the lifting stability of lifting plate 216. When lifting plate 216 rises and falls, it drives detection probe 221 to rise and fall, thereby moving detection probe 221 to the z-axis coordinate of detection point. At this time, the three-dimensional coordinate position of detection probe 221 is the same as the three-dimensional coordinate position of detection point, which makes it convenient for detection probe 221 to detect the designated detection point.

[0019] The working principle of this new type of large three-dimensional medical water tank used for radiotherapy quality control testing will be explained in detail below.

[0020] like Figure 1-4As shown, by starting the motor 206 according to the three-dimensional coordinates of the detection point, the gear 208 is driven to rotate. The gear 208 meshes with the ring rack 202 and rotates, driving the motor 206 to rotate. When the motor 206 rotates, it drives the slider 203 to slide in the annular groove 201 through the connecting frame 205. The slider 203 is connected to the annular groove 201 and the connecting frame 205 to support the motor 206. The motor 206 is connected to the connecting column 209 through the connecting rod 207. When the motor 206 rotates, it is connected to the connecting rod 207 and the connecting column... 209 drives slider 204 to rotate within the ring rack 202, which in turn drives gear 210 to mesh and rotate with the ring rack 202. Slider 204, connected to the ring rack 202 and connecting column 209, supports gear 210. When gear 1 208 and gear 210 mesh and rotate with the ring rack 202, they drive connecting rod 207 to rotate via motor 1 206 and connecting column 209. Connecting rod 207 connects to connecting plate 211, causing the connecting plate 211 to rotate, and through the connecting plate 211, the lifting plate 216 to rotate. The lifting plate 216 device adjusts the coordinate position of the detection probe 221 by rotating the moving block 220. When the connecting rod 207 rotates to the specified angle, the motor 1 206 is turned off. At this time, the angle between the connecting rod 207 and the x-axis and y-axis is equal to the angle between the detection point and the x-axis and y-axis. The motor 3 218 is started to drive the lead screw 219 to rotate. When the lead screw 219 rotates, it drives the moving block 220 and the detection probe 221 to move, thereby moving the detection probe 221 to the x and y coordinates of the detection point. After reaching the designated coordinate, motor 214 is started to drive lead screw 215 to rotate. Lead screw 215 is connected to lifting plate 216 to drive lifting plate 216 to rise and fall. Slide rod 212 is connected to lifting plate 216 to improve the stability of lifting plate 216. When lifting plate 216 rises and falls, it drives detection probe 221 to rise and fall, thereby moving detection probe 221 to the z-axis coordinate of detection point. At this time, the three-dimensional coordinate position of detection probe 221 is the same as the three-dimensional coordinate position of detection point, which makes it convenient for detection probe 221 to detect the designated detection point.

[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
