In the medical field, imaging scanning technology is widely used to visualize the internal structure of the human body, helping doctors to accurately judge the condition and formulate treatment plans. Traditional methods mostly use X-rays, CT, MRI and other methods to achieve imaging scanning.

[0003] In the existing technology, scanning equipment can usually only realize a single scanning platform movement, which not only limits the scanning speed, but also may cause instability and errors in the scanning process. When the palm is in a disabled state, the patient cannot independently control the extension of the fingers. The existing scanning equipment often ignores the situation of the fingers being together, and there is no effective mechanism to ensure that the fingers are spread and flat during the scanning process, which affects the clarity and accuracy of the scanning image, and then affects the subsequent recognition and analysis process.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 - Figure 4The present invention provides a technical solution: an imaging scanning drive device, comprising a supporting mechanism 1, the supporting mechanism 1 comprising a base 11 as a base, the upper end surface of the base 11 is symmetrically fixedly connected with a slide 12, and a placement plate 13 for placing palms is slidably connected to the opposite side of the two slides 12, the outer wall of the base 11 is fixedly connected with a supporting frame 14, the upper end surface of the supporting frame 14 is fixedly connected with a protective frame 15, the upper end surface of the base 11 is located below the slide 12 and is symmetrically fixedly connected with a U-shaped frame 16, a displacement mechanism 2 is arranged on the opposite side of the two U-shaped frames 16, a guiding mechanism 3 for driving the placement plate 13 and the local structure of the displacement mechanism 2 to move synchronously is arranged above the two U-shaped frames 16, a driving mechanism 4 for driving the displacement mechanism 2 to work is arranged inside the protective frame 15, an expansion mechanism 6 for expanding fingers is arranged inside the placement plate 13, and a compression mechanism 5 for providing a power source for the expansion mechanism 6 is arranged inside the protective frame 15 at one side of the driving mechanism 4.

[0021] By adopting the above technical scheme, the symmetrically arranged slide 12 is slidably connected to the placement plate 13, so that palms of different sizes can be properly placed, realizing personalized adjustment. The design of the slide 12 is also convenient for quickly positioning and fixing the palm position, thereby improving the scanning efficiency. The ingenious setting of the displacement mechanism 2 enables the scanning head 19 to move accurately along the predetermined trajectory, covering the entire palm area, realizing a comprehensive and detailed scan. The introduction of the guide mechanism 3 realizes the synchronous movement of the placement plate 13 and the local structure of the displacement mechanism 2. This innovative design not only enhances the stability during the scanning process, but also enables the scanning head 19 to always maintain an optimal distance from the palm, thereby improving the quality of the scanned image. By accurately controlling the working state of the driving mechanism 4, the scanning speed and accuracy can be flexibly adjusted to meet the needs of different application scenarios. The expansion mechanism 6 can appropriately expand the fingers, effectively solving the problem of scanning blind spots caused by close fit of the fingers, making the scanning results more complete and accurate.

[0022] See also Figure 2 - Figure 5 A slide groove 17 is provided on the opposite side of the two U-shaped frames 16, and tooth grooves 18 are evenly provided inside the two U-shaped frames 16. The lower end surface of the placement plate 13 is symmetrically fixedly connected with a first fixed bracket 131, and the lower end surface of the slide 12 is symmetrically fixedly connected with a second fixed bracket 132. A damping resetter 133 is fixedly connected by bolts at the interval between the first fixed bracket 131 and the second fixed bracket 132 to facilitate the reset of the placement plate 13.

[0023] By adopting the above technical solution, the slide groove 17 design opened on the opposite side of the two U-shaped frames 16 provides a stable and smooth sliding path for the placement plate 13 and its connecting parts, ensuring that the fine-tuning of the palm position during the scanning process can be carried out accurately and smoothly. At the same time, the tooth grooves 18 evenly opened inside the U-shaped frame 16 provide precise engagement points for subsequent engagement, ensuring that the displacement mechanism 2 can accurately drive the placement plate 13 and the palm thereon to perform scanning movement. The introduction of the damping resetter 133 can automatically help the placement plate 13 to reset to the initial position after the scanning is completed, thereby simplifying the operation process and improving work efficiency. At the same time, the buffering effect of the damping resetter 133 can also effectively reduce the impact and noise caused by rapid reset, thereby improving the user experience.

[0024] See also Figure 4 - Figure 7 The displacement mechanism 2 includes an upper moving frame 21 and a lower moving frame 22 arranged in a mirror-like manner. The upper moving frame 21 and the lower moving frame 22 have a plurality of scanning heads 19 fixedly connected to opposite sides thereof for scanning human palms. The outer walls of the upper moving frame 21 and the lower moving frame 22 are fixedly connected to hanging plates 24. The sides of the plurality of hanging plates 24 away from the upper moving frame 21 and the lower moving frame 22 are rotatably sleeved with movable wheels 26, and the movable wheels 26 are slidably connected to the inside of the slide groove 17. The outer walls of the upper moving frame 21 and the lower moving frame 22 are rotatably sleeved with fixed rods 23. The ends of the two fixed rods 23 are fixedly connected to gears 25 meshing with the tooth grooves 18 for transmission. The outer wall of the fixed rod 23 connected to the upper moving frame 21 is fixedly sleeved with a first synchronous wheel 231, and the outer wall of the fixed rod 23 connected to the lower moving frame 22 is fixedly sleeved with a first bracket 221.

[0025] By adopting the above technical scheme, a plurality of scanning heads 19 are evenly distributed on opposite sides of the upper moving frame 21 and the lower moving frame 22, so as to perform meticulous scanning of various parts of the palm, ensuring a clear understanding of the bones of the palm after the scanning is completed. The smooth sliding of the movable wheel 26 inside the slide groove 17 ensures that the upper moving frame 21 and the lower moving frame 22 can move smoothly along the predetermined trajectory, thereby realizing the comprehensive coverage of the palm by the scanning head 19. The gear 25 at the end of the fixed rod 23 is meshed with the tooth groove 18 inside the U-shaped frame 16 to realize precise positioning and motion control of the displacement mechanism 2. The first synchronous wheel 231 fixedly sleeved on the outer wall of the fixed rod 23 connected to the upper moving frame 21 and the first bracket 221 fixedly sleeved on the outer wall of the fixed rod 23 connected to the lower moving frame 22 provide important structural support for the synchronous movement and fixed connection of the displacement mechanism 2.

[0026] See also Figure 4 - Fig.10The outer wall of the two fixed rods 23 is located at one side of the first bracket 221 and the first synchronous wheel 231, and is rotatably connected to a V-shaped limit plate 27 through a bearing. The V-shaped limit plate 27 is rotatably connected to the first bracket 221 and the first synchronous wheel 231.

[0027] By adopting the above technical scheme, the rotational connection between the V-shaped limit plate 27 and the first bracket 221 and the first synchronous wheel 231 further improves the flexibility of the structure, so that the V-shaped limit plate 27 can play a supporting effect and limit the lower moving frame 22 at the same time, ensuring that the upper moving frame 21 and the lower moving frame 22 move synchronously. The limit push frame 281 fixedly connected at both ends of the synchronous plate 28 not only enhances the structural strength of the synchronous plate 28, but also provides a reliable support point for its connection with the first bracket 221 and other components. In particular, the limit push frame 281 close to the side of the lower moving frame 22 is rotatably sleeved on the outer wall of the first bracket 221. This design not only ensures the synchronous movement between the synchronous plate 28 and the lower moving frame 22, but also realizes further limiting and stabilization of the first bracket 221 through the rotational connection of the limit push frame 281.

[0028] See also Figure 4 - Figure 7 The guide mechanism 3 includes a mounting plate 31 fixedly connected to the upper end surfaces of the two U-shaped frames 16, and guide wheels 32 are symmetrically rotatably sleeved on the opposite sides of the two mounting plates 31. A limiting block 33 is fixedly connected at the edge of the upper end surface of the upper moving frame 21 and the center of the side of the placement plate 13 close to the protective frame 15. A guide rope 34 is arranged between the two limiting blocks 33. The guide rope 34 is wound around the outer walls of the two guide wheels 32, and the guide wheel 32 is slidably connected to the two guide ropes 34.

[0029] By adopting the above technical solution, the guide mechanism 3 can be firmly installed at the key position of the scanning system by fixing the mounting plate 31 connected to the upper end surfaces of the two U-shaped frames 16. The mounting plate 31 not only provides reliable support for components such as the guide wheels 32, but also ensures the structural stability and durability of the entire guide mechanism 3. The two guide wheels 32 are symmetrically rotatable and sleeved on opposite sides of the mounting plate 31. Their presence provides necessary guidance and support for the smooth sliding of the guide rope 34. The two limit blocks 33 are connected by the guide rope 34 and are wrapped around the outer walls of the two guide wheels 32, thereby realizing precise control and guidance of the motion trajectory of the displacement mechanism 2.

The outer walls of the first synchronous wheel 231 and the second synchronous wheel 44 are sleeved with a synchronous belt 45. The inner wall of the protection frame 15 is symmetrically fixedly connected with a second electric push rod 46. The telescopic end of the second electric push rod 46 is fixedly connected to the outer wall of the bearing plate 41. The output end of the driving motor 42 away from the first driving rod 43 is fixedly connected with a second driving rod 47, and the end of the second driving rod 47 is fixedly connected with a cam 48.

[0031] By adopting the above technical scheme, the driving motor 42 serves as the power source of the driving mechanism 4, and its performance directly affects the movement speed and accuracy of the scanning head 19. The first driving rod 43 passes through the protective frame 15 and is slidably connected to the protective frame 15. The second synchronous wheel 44 fixed on its outer wall is connected to the first synchronous wheel 231 through a synchronous belt 45, thereby realizing the synchronous movement between the displacement mechanism 2 and the driving motor 42, which not only simplifies the structure of the driving mechanism 4, but also improves the transmission accuracy and reliability. At the same time, the end of the first driving rod 43 is also fixedly connected to the second bracket 222, and the rotational connection with the V-shaped limit plate 27 further enhances the stability of the structure and the stability of the movement. The introduction of the second electric push rod 46 provides additional power support for the driving mechanism 4, and its telescopic end is fixedly connected to the outer wall of the load-bearing plate 41. By adjusting the telescopic length of the second electric push rod 46, the linear position adjustment of the load-bearing plate 41 and the entire driving mechanism 4 can be realized, thereby meeting the position adjustment under different scanning requirements.

[0032] See also Fig.11 and Fig.12 The compression mechanism 5 includes a guide frame 51 which is symmetrically fixedly connected to the upper end surface of the load-bearing plate 41, a piston rod 52 is slidably sleeved inside the guide frame 51, and rollers 54 are rotatably sleeved on the ends of the two piston rods 52 on one side close to the cam 48, a positioning plate 53 is fixedly connected to the outer wall of the piston rod 52, and a limit spring 56 is fixedly connected to the side of the positioning plate 53 close to the guide frame 51 to ensure that the roller 54 abuts against the end surface of the cam 48, and a piston head body 55 is fixedly connected to the end of the piston rod 52 away from the cam 48. The upper end surface of the load-bearing plate 41 is located on one side of the guide frame 51 and is symmetrically fixedly connected to a piston cylinder 57, and the piston head body 55 is slidably sleeved inside the piston cylinder 57, and the intake ends of the two piston cylinders 57 are provided with intake valves 58.

[0033] With the above technical solution, the guide frame 51 is used as the basic structure of the compression mechanism 5, and is symmetrically fixedly connected to the upper end surface of the load-bearing plate 41, providing a stable guide for the sliding of the piston rod 52. The piston rod 52 is slidably sleeved inside the guide frame 51, and a roller 54 is rotatably sleeved on the end portion of the piston rod 52 close to the cam 48. The roller 54 not only reduces the friction resistance between the cam 48 and the piston rod 52, but also improves the smoothness and durability of the movement. When the cam 48 rotates, the change in its profile will push the roller 54 and the piston rod 52 to reciprocate along the guide frame 51. The existence of the limit spring 56 ensures that the roller 54 always abuts against the end surface of the cam 48, even if the cam 48 is rotated. Even when the wheel 48 has a large profile change, it can still maintain stable contact and transmission, which not only improves the accuracy and reliability of the transmission, but also provides the necessary restoring force for the reciprocating motion of the piston rod 52. When the piston rod 52 reciprocates, the piston head body 55 will slide inside the piston cylinder 57, thereby changing the volume and pressure of the gas in the cylinder. The two piston cylinders 57 are provided with intake valves 58 at the intake ends. This design allows external gas to enter the piston cylinder 57 when needed, providing the necessary initial conditions for gas compression. At the same time, the opening and closing of the intake valve 58 can be precisely controlled according to actual needs, thereby achieving flexible adjustment of the gas injection.

[0035] With the above technical solution, the intelligent control gas plate 61 is used as the core component of the expansion mechanism 6, and the advanced control technology and constant pressure valve 63 are integrated inside, which can realize the precise control and stable output of the gas pressure. By being fixedly connected inside the placement plate 13, the intelligent control gas plate 61 can be conveniently connected to the first air pipe 62 and other components to provide a stable and reliable gas supply for the finger gap airbag 64 and other actuators. Through the precise control of the intelligent control gas plate 61, the finger gap airbag 64 can simulate the opening and closing movements of the fingers, so as to realize the close fit and effective fixation of the scanned object, which not only improves the scanning accuracy, but also improves the scanning precision. The three-way pipe 67 and the corrugated air pipe 66 provide a more flexible and convenient path for the transmission of gas from the piston cylinder 57 to the intelligent control air plate 61. The telescopic design of the corrugated air pipe 66 enables it to adapt to the gas transmission needs at different positions and angles, thereby improving the adaptability and flexibility of the entire expansion mechanism 6. By accurately controlling the opening and closing of the exhaust valve 69, the gas discharge speed and discharge amount can be accurately regulated, thereby ensuring the stability and controllability of the gas pressure inside the intelligent control air plate 61.

[0036] See also Fig. 9 and Fig.10 The outer wall of the protective frame 15 is fixedly connected to a first electric push rod 29, the telescopic end of the first electric push rod 29 is fixedly connected to a mounting bracket 291, and the mounting bracket 291 is slidably connected to the outer wall of the protective frame 15, and the outer wall of the mounting bracket 291 is fixedly connected to the outer wall of the V-shaped limiting plate 27.

[0037] By adopting the above technical solution, the telescopic end of the first electric push rod 29 is cleverly fixedly connected to the mounting frame 291. The adoption of this connection method enables the mounting frame 291 to move flexibly with the telescopic action of the first electric push rod 29, thereby greatly increasing the flexibility and adaptability of the operation. Through the close combination with the mounting frame 291, the precise positioning and effective restraint of the limited object can be achieved, thereby greatly improving the safety and reliability of the entire displacement mechanism 2.

[0038] A driving method for an imaging scanning driving device, see Figure 1 - Fig.13 , S1, place the palm on the upper end surface of the placement plate 13, and insert the middle finger and the ring finger into the gap formed by the finger gap airbag 64, then the driving mechanism 4 starts to work and drives the displacement mechanism 2 to move, and the upper moving frame 21 and the lower moving frame 22 will form a synchronous movement, and the upper and lower areas of the palm are scanned by the scanning head 19; S2. During the movement of the upper moving frame 21, the guide rope 34 will be pulled. At this time, the placement plate 13 will realize linear motion through the guide rope 34 under the movement of the upper moving frame 21. The movement direction of the upper moving frame 21 is opposite to that of the placement plate 13. During the scanning process of the scanning head 19, the upper moving frame 21 can cooperate with the placement plate 13 to speed up the scanning progress. S3. After the driving mechanism 4 starts working, an output end of the driving motor 42 drives the second driving rod 47 to rotate, and then drives the cam 48 to rotate, and cooperates with the compression mechanism 5, so that the compression mechanism 5 can generate gas, and the gas is transported to the finger gap airbag 64 through the expansion mechanism 6. The finger gap airbag 64 will expand after being filled with gas, and squeeze the finger to expand it to the surroundings, which can make the scanning process of the scanning head 19 more accurate and avoid the situation where the scanning accuracy is reduced due to the fingers being close together.

[0039] For scanning of human palms: when scanning the palms, it is necessary to first place the palms on the upper end surface of the placement plate 13, and insert the middle finger and the ring finger into the gaps formed by several finger gap airbags 64, and then start the drive motor 42 to drive the first drive rod 43 to rotate. After the first drive rod 43 rotates, it will drive the second synchronous wheel 44 and the synchronous belt 45 to rotate, and the synchronous belt 45 is sleeved on the outer walls of the second synchronous wheel 44 and the first synchronous wheel 231, so that the first synchronous wheel 231 and the fixed rod 23 can be driven to rotate. Since gears 25 are respectively provided at both ends of the fixed rod 23, the gear 25 meshes with the tooth grooves 18 opened inside the U-shaped frame 16. At this time, the rotation of the gear 25 can move back and forth inside the U-shaped frame 16, and push the upper moving frame 21 to move. By providing a V-shaped limit plate 27, it can The lower moving frame 22 is driven to move synchronously. During the movement of the upper moving frame 21, the first clamping frame 221 will be pushed to move through the V-shaped limit plate 27, the synchronous plate 28 and the limit push frame 281, so as to achieve the purpose of driving the lower moving frame 22 synchronously. Since the upper moving frame 21 and the lower moving frame 22 are synchronously moved through the V-shaped limit plate 27, when the V-shaped limit plate 27 moves, the telescopic end of the first electric push rod 29 will push the mounting frame 291 to move, thereby driving the V-shaped limit plate 27 to move, and the telescopic end of the second electric push rod 46 will also push the load-bearing plate 41, thereby cooperating with the V-shaped limit plate 27 to realize the movement of the upper moving frame 21 and the lower moving frame 22, and the upper moving frame 21 and the lower moving frame 22 are provided with a scanning head 19 at the opposite end, through which the palm can be scanned and transmitted to an external imaging device; Supplementary explanation of the guide mechanism 3 and the expansion mechanism 6: When the upper moving frame 21 moves, the guide rope 34 will be pulled, and the guide rope 34 is wound around the outer wall of the two guide wheels 32, and the other end is connected to the end of the placement plate 13. Therefore, when the upper moving frame 21 pulls the guide rope 34 to move, the guide wheel 32 will rotate to reduce the friction force, and will pull the placement plate 13, and the placement plate 13 slides on the outer wall of the slide 12. At this time, the upper moving frame 21 and the lower moving frame 22 move away from the protective frame 15, and the placement plate 13 moves toward the protective frame 1 5, by this method, the time required for scanning can be reduced, and the scanning can be performed synchronously. After the driving motor 42 works, it can synchronously drive the second driving rod 47 to rotate, and the driving motor 42 is a dual-axis motor. When the second driving rod 47 drives the cam 48 to rotate, it will cooperate with the two piston rods 52, and a sliding connection is formed between the end face of the cam 48 and the roller 54 at the end of the piston rod 52. When the convex surface of the end face of the cam 48 contacts the piston rod 52, the piston rod 52 moves and squeezes the limit spring 56, and the end of the piston rod 52 is provided with a piston head The piston head body 55 is located inside the piston cylinder 57. At this time, the piston head body 55 reciprocates and accelerates the airflow inside the piston cylinder 57. The gas is sent into the second air pipe 65 and the inside of the intelligent control air plate 61 through the three-way pipe 67 and the corrugated air pipe 66. The intelligent control air plate 61 sends the gas into the inside of the finger gap air bag 64 through the first air pipe 62. At this time, the finger gap air bag 64 will expand and squeeze and support the fingers. At this time, the fingers will move around when squeezed, and will tend to be straight after being supported, and will be at the same height as the back of the hand. There will be no low finger area, and the palm scan will be more accurate. At the same time, the reciprocating motion of the two piston rods 52 and the piston head body 55 can speed up the gas movement speed, and a constant pressure valve 63 is also provided inside the intelligent control gas plate 61 to ensure the stability of the gas inside the finger airbag 64 to avoid excessive gas. Excessive gas will be controlled by the intelligent control gas plate 61 to control the exhaust valve 69 to open. At this time, the gas inside the intelligent control gas plate 61 and the finger airbag 64 will be discharged through the exhaust pipe 68, thereby stabilizing the gas.
