Description

Technical Field

[0001] This invention relates to an adjustment device for a scanning device, and more particularly to a shape and position adjustment mechanism, a scanning device, and a medical device. Background Technology

[0002] In current medical imaging technologies, especially in the field of computed tomography (CT), precise positioning of the object being scanned is one of the key factors in ensuring image clarity. Traditional CT scanning equipment or devices mostly adopt a horizontal layout, that is, the CT machine is vertically fixed to the ground, and the object being scanned is horizontally fed into the scanning section of the CT machine via a slide rail or robotic arm for scanning.

[0003] However, with the continuous advancement of medical technology and the diversification of clinical needs, new application scenarios are placing higher demands on CT scanning equipment. In particular, in certain specific CT scanning applications, the object being scanned needs to be vertically fixed and rotated in a full circle to obtain comprehensive image data. This vertical layout not only requires the object to remain stable during rotation, preventing it from falling or slipping due to its own gravity, but also requires the scanning equipment to precisely adjust the position of the object to meet the adjustment requirements of six degrees of freedom (i.e., translation along the X, Y, and Z axes and rotation around the X, Y, and Z axes).

[0004] Traditional horizontal CT scanners are ill-suited for vertical scanning requirements. On one hand, horizontal CT scanners cannot directly adapt to the scanning requirements of vertical layouts; on the other hand, even with complex mechanical structures to vertically fix the object being scanned, it is difficult to guarantee that it will not misalign, slip, or fall during rotation, thus affecting the accuracy and safety of the scan results.

[0005] Furthermore, with the continuous development of CT technology, the application of vertical CT scanning equipment is increasing. This vertical layout not only improves scanning efficiency but also allows the object to be scanned to slide more easily into the CT scanning unit. However, this also places new demands on the object sliding mechanism. For example, when the object to be scanned needs to be suspended and fixed under the gantry of the CT scanning equipment, it is essential to ensure the stability and safety of the object during the scanning process. Summary of the Invention

[0006] To address at least one of the aforementioned technical problems, the present invention provides a shape and position adjustment mechanism, a scanning device, and a medical device, which can reciprocate and adjust the shape and position of the positioning plate in the directions of rotation around the X-axis and rotation around the Y-axis, greatly improving the positioning accuracy of the scanned object during the scanning process and ensuring the accuracy of the scanning results.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] On one hand, the present invention provides a form and position adjustment mechanism, comprising:

[0009] A positioning plate, the positioning plate including a first surface and a second surface disposed opposite to each other, the second surface abutting against the part to be scanned, the second surface including a first fold line and a second fold line that are perpendicular to each other;

[0010] An adjustment part, the adjustment part being connected to the first surface, the adjustment part comprising:

[0011] A first fine-tuning component drives the first polygonal line to reciprocate in the Y-axis direction around the normal vector of the positioning plate;

[0012] The second fine-tuning component drives the second polyline to reciprocate around the first polyline in the X-axis direction.

[0013] The beneficial effects of the above solution are as follows: By setting a positioning plate containing mutually perpendicular first and second fold lines, and corresponding first and second fine-tuning components, the shape and position adjustment mechanism can reciprocate and adjust the shape and position of the positioning plate in the directions of rotation around the X-axis and rotation around the Y-axis. This greatly improves the positioning accuracy of the scanned object during the scanning process and ensures the accuracy of the scanning results. At the same time, since fine-tuning can be performed in two mutually perpendicular directions, the scanning flexibility is further improved, enabling it to adapt to scanned objects of different shapes and sizes and meet different scanning needs.

[0014] Furthermore, the aforementioned form and position adjustment mechanism also includes:

[0015] The translation section includes a first translation component and a second translation component. The first translation component drives the positioning plate to reciprocate along the Y-axis, and the second translation component drives the positioning plate to reciprocate along the X-axis.

[0016] Furthermore, the aforementioned form and position adjustment mechanism also includes:

[0017] A lifting unit, which drives the positioning plate to reciprocate along the Z-axis;

[0018] Furthermore, the aforementioned form and position adjustment mechanism also includes:

[0019] The rotating part drives the positioning plate to rotate clockwise or counterclockwise around the Z-axis in the XOY plane.

[0020] The beneficial effects of the above solution are as follows: by setting up translation, lifting and / or rotation parts, the positioning plate can not only move and adjust in the X and Y axis directions, but also translate in these two directions, lift in the Z axis direction, and even rotate in the XOY plane, which greatly expands the application range of the form and position adjustment mechanism and enables it to meet the needs of more complex scanning scenarios.

[0021] Furthermore, both the first fine-tuning component and the second fine-tuning component include:

[0022] A connecting block, wherein the connecting block is disposed on the first side of the positioning plate;

[0023] A damper, wherein the damper is connected to the connecting block;

[0024] A rotating motor drives the damper to rotate the connecting block clockwise or counterclockwise around the Y-axis or around the X-axis.

[0025] The beneficial effects of the above scheme are as follows: the connecting block, damper, and rotating motor not only make the structure of the fine-tuning component more compact, but the rotating motor also provides a power source, and the damper improves the stability of the adjustment, ensuring the accuracy and reliability of the fine-tuning process.

[0026] Furthermore, the second translation component includes: a second carrier plate and a second telescopic linear actuator, the cylinder of the second telescopic linear actuator is connected to the second carrier plate, and the connecting end of the second telescopic linear actuator is connected to the adjustment part, so that the positioning plate reciprocates along the X-axis;

[0027] The first translation component includes a first carrier plate and a first telescopic linear actuator. The cylinder of the first telescopic linear actuator is connected to the first carrier plate, and the connecting end of the first telescopic linear actuator is connected to the second carrier plate, so that the positioning plate reciprocates along the Y-axis.

[0028] The beneficial effects of the above solution are: it not only simplifies the structure of the translation unit, but also improves the accuracy and stability of the translation, thereby ensuring the accurate position of the object to be scanned during the scanning process.

[0029] Furthermore, the lifting unit includes:

[0030] A lifting linear actuator, the connecting end of which is connected to the translation unit, drives the positioning plate to reciprocate along the Z-axis.

[0031] The beneficial effects of the above scheme are: the lifting linear actuator, as a power source, enables the positioning plate to be lifted and lowered in the Z-axis direction, thereby improving the accuracy and stability of the lifting.

[0032] Furthermore, the lifting unit also includes a lifting frame, which comprises:

[0033] A first support plate and a second support plate are arranged opposite to each other, the first support plate is connected to the cylinder body of the lifting linear actuator, and the second support plate is connected to the connecting end of the lifting linear actuator;

[0034] Multiple telescopic poles, each with its first end connected to the first support plate and its second end connected to the second support plate.

[0035] The beneficial effects of the above solution are as follows: by setting up a first support plate, a second support plate, and multiple telescopic rods, not only is the load-bearing capacity of the lifting frame enhanced, but the addition of telescopic rods also improves the stability and safety of the lifting process, thereby ensuring the stable position of the workpiece to be scanned during the scanning process.

[0036] Furthermore, the rotating part includes:

[0037] A slewing bearing, which is connected to the lifting unit;

[0038] The worm gear is coupled to the slewing bearing;

[0039] A hydraulic motor drives the worm gear to rotate the slewing bearing.

[0040] The beneficial effects of the above solution are as follows: by incorporating a worm gear and a hydraulic motor, the accuracy and stability of rotation are improved. Specifically, the hydraulic motor, as a power source, provides sufficient torque to drive the rotation of the slewing bearing, thereby ensuring the smoothness and reliability of the rotation process.

[0041] Furthermore, the initial position of the positioning plate is such that the first broken line is parallel to the Y-axis.

[0042] The beneficial effect of the above scheme is that it enables vertical scanning.

[0043] In a second aspect, the present invention provides a scanning device, comprising:

[0044] The aforementioned form and position adjustment mechanism;

[0045] The CT scanning unit has a scanning area that corresponds to the external position of the workpiece to be scanned, which is connected to the positioning adjustment mechanism.

[0046] A lifting assembly, the first end of which is connected to a mounting platform, and the second end of which is connected to the CT scanning unit.

[0047] The beneficial effects of the above solution are as follows: By combining the position adjustment mechanism and the CT scanning unit, and using the lifting assembly to raise and lower the CT scanning unit, the flexibility and adaptability of the scanning device are improved. Furthermore, the addition of the position adjustment mechanism enables precise adjustment of the scanned object in multiple directions, thereby ensuring the accuracy and reliability of the scanning results.

[0048] Thirdly, the present invention provides a medical device, characterized in that it comprises:

[0049] The aforementioned scanning device;

[0050] A control system that controls the positioning adjustment mechanism and the lifting assembly.

[0051] The beneficial effects of the above solution are as follows: by setting up a control system to control the movement of the positioning adjustment mechanism and the lifting components, precise control of the scanning process can be achieved. This not only improves the automation level of medical equipment, but also enables real-time monitoring and adjustment of the scanning process through the addition of the control system, thereby ensuring the accuracy and safety of the scanning results.

[0052] Compared with the prior art, the beneficial effects of the present invention include at least the following:

[0053] By setting a positioning plate containing mutually perpendicular first and second zigzag lines, along with corresponding first and second fine-tuning components, the shape and position adjustment mechanism can reciprocate and adjust the shape and position of the positioning plate in the directions of rotation around the X-axis and Y-axis. This greatly improves the positioning accuracy of the scanned object during scanning and ensures the accuracy of the scanning results. Furthermore, the ability to fine-tune in two mutually perpendicular directions further enhances scanning flexibility, enabling it to adapt to scanned objects of different shapes and sizes and meet diverse scanning needs.

[0060] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0061] The terms used to express position and direction in this invention are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0062] Existing vertical CT scanning equipment has many shortcomings during operation, especially in terms of the position adjustment and stability of the scanned object. Therefore, in order to fix the scanned object vertically and precisely adjust its position through six degrees of freedom motion adjustment, while reducing the risk of misalignment, slippage or falling during shape and position changes, this invention proposes a shape and position adjustment mechanism 100, a scanning device and medical equipment.

[0063] refer to Figure 2 To enable the positioning plate 1 to achieve precise reciprocating movement adjustment in the directions of rotation around the X-axis and rotation around the Y-axis, the form and position adjustment mechanism 100 of the present invention includes a positioning plate 1 and an adjustment part 2. Furthermore, to enable the positioning plate 1 to not only move and adjust in the directions of rotation around the X-axis and rotation around the Y-axis, but also translate in both the X and Y axes, and lift and lower in the Z-axis direction, and even rotate around the Z-axis, the form and position adjustment mechanism 100 of the present invention may further include a translation part 3, a lifting part 4, and a rotating part 5.

[0064] refer to Figure 1The positioning plate 1 includes a first side 11 and a second side 12, a third side 13 and a fourth side 14 arranged opposite to each other, and a first fold line 101 and a second fold line 102 that are perpendicular to each other. The first fold line 101 is parallel to the first side 11 and the second side 12, and the second fold line 102 is parallel to the third side 13 and the fourth side 14. Further, the positioning plate 1 can be circular, rectangular, square, polygonal, or irregularly shaped, and its initial position is vertical. Specifically, in the initial state, the first fold line 101 is parallel to the Y-axis, and the second fold line 102 is perpendicular to the Y-axis. In application, the positioning plate 1 also includes a normal vector (not shown) and a first surface (not shown) and a second surface (not shown) arranged opposite to each other. The second surface of the positioning plate 1 abuts against the workpiece to be scanned, and the normal vector of the positioning plate 1 is perpendicular to the positioning plate 1. In practical applications, a fixing element can be provided on the second surface of the positioning plate 1 according to the actual situation. The fixing component is made of transparent plastic and is compatible with the operating mechanism of the scanning device, so it will not generate interference factors such as static electricity or friction during the scanning process.

[0065] The adjustment unit 2 of the present invention includes a first fine-tuning component (not shown) and a second fine-tuning component (not shown). The first fine-tuning component drives the first broken line 101 to reciprocate around the normal vector of the positioning plate 1 in the Y-axis direction for adjustment. The second fine-tuning component drives the second broken line 102 to reciprocate around the first broken line 101 in the X-axis direction for adjustment.

[0066] refer to Figure 3 Both the first and second fine-tuning components include a connecting block 21, a damper 22, and a rotary motor 23. Specifically, the rotary motor 23 drives the connecting damper 22, which is connected to the connecting block 21, and the connecting block 21 is located on the first surface of the positioning plate 1. In application, the rotary motor 23 can rotate clockwise or counterclockwise. The rotary motor 23 drives the damper 22 to rotate, causing the damper 22 to drive the connecting block 21 to rotate, thereby causing the positioning plate 1 to rotate clockwise or counterclockwise in the direction of rotation around the Y-axis or around the X-axis.

[0067] Furthermore, the first fine-tuning component includes: a first connecting block (not shown), a first damper (not shown), and a first rotary motor (not shown). The second fine-tuning component includes: a second connecting block (not shown), a second damper (not shown), and a second rotary motor (not shown). The first and second connecting blocks are regular hexahedrons. Specifically, both the first and second connecting blocks include a top and bottom surface opposite to each other, a first and a third side surface opposite to each other, and a second and a fourth side surface opposite to each other. The first, second, third, and fourth side surfaces are connected end-to-end to form a side surface perpendicular to the top and bottom surfaces.

[0068] In some preferred embodiments, the first side of both the first connecting block and the second connecting block is connected to the middle of the first side.

[0069] The output of the first rotary motor drives the input of the first damper, and the output of the first damper is connected to the third side of the first connecting block. In application, the first rotary motor rotates through the first driving damper, causing the first damper to drive the first connecting block to rotate clockwise or counterclockwise, thereby causing the positioning plate 1 to reciprocate and adjust in the direction of rotation around the X-axis. For example, adjusting the angle between the first broken line 101 and the Y-axis.

[0070] The output of the second rotary motor drives the input of the second damper, and the output of the second damper is connected to the fourth or second side of the second connecting block. In application, the second rotary motor rotates via the second drive damper, causing the second damper to rotate the second connecting block clockwise or counterclockwise, thereby causing the positioning plate 1 to reciprocate and adjust in the direction of rotation around the Y-axis. For example, adjusting the angle between the first fold line 101 and the X-axis.

[0071] The translation unit 3 of the present invention includes a first translation component (not shown) and a second translation component (not shown). Specifically, the first translation component drives the positioning plate 1 to reciprocate along the Y-axis, and the second translation component drives the positioning plate 1 to reciprocate along the X-axis.

[0072] refer to Figure 3 The first translation component of the present invention includes a first carrier plate 311 and a first telescopic linear actuator 312, and the second translation component includes a second carrier plate 321 and a second telescopic linear actuator 322.

[0073] The cylinder of the first telescopic linear actuator 312 is connected to the first carrier plate 311, and the connecting end of the first telescopic linear actuator 312 is connected to the second carrier plate 321, so that the positioning plate 1 reciprocates along the Y-axis. In application, the first carrier plate 311 is mounted on the bracket of the lifting part 4. When the connecting end of the first telescopic linear actuator 312 extends outward, the positioning plate 1 moves along the first direction of the Y-axis. When the connecting end of the first telescopic linear actuator 312 retracts, the positioning plate 1 moves along the second direction of the Y-axis. In actual application, the second direction is opposite to the first direction, and in the initial state, the extension length of the cylinder rod (or piston rod) of the first telescopic linear actuator 312 is half of the range of the first telescopic linear actuator 312. The range is the total stroke length of the linear actuator from fully retracted to fully extended.

[0074] The cylinder of the second telescopic linear actuator 322 is connected to the second carrier plate 321, and the connecting end of the second telescopic linear actuator 322 is connected to the adjusting part 2 to allow the positioning plate 1 to reciprocate along the X-axis. In application, the connecting end of the second telescopic linear actuator is connected to the bracket of the adjusting part 2. When the connecting end of the second telescopic linear actuator 322 extends outward, the positioning plate 1 moves along the third direction of the X-axis; when the connecting end of the second telescopic linear actuator 322 retracts, the positioning plate 1 moves along the fourth direction of the X-axis. In practical applications, the fourth direction is opposite to the third direction and perpendicular to the second direction. Furthermore, in the initial state, the extension length of the cylinder rod (or piston rod) of the second telescopic linear actuator 322 is half the range of the second telescopic linear actuator 322.

[0075] The lifting part 4 of the present invention drives the positioning plate 1 to reciprocate along the Z-axis.

[0076] refer to Figure 3 To achieve the lifting and lowering of the positioning plate 1 in the Z-axis direction, thereby improving the accuracy and stability of the lifting, the lifting part 4 of the present invention includes a lifting linear actuator 41. Furthermore, to enhance the load-bearing capacity of the lifting part 4 and ensure the stable position of the workpiece to be scanned during the scanning process, the lifting part 4 of the present invention may also include a lifting frame (not shown). Specifically, the connecting end of the lifting linear actuator 41 drives the translation part 3 to drive the positioning plate 1 to reciprocate along the Z-axis. The second end of the lifting frame is connected to the connecting end of the lifting linear actuator 41, and the first end of the lifting frame is connected to the cylinder of the lifting linear actuator 41 to limit the displacement of the positioning plate 1. In application, when the connecting end of the lifting linear actuator 41 extends outward, the positioning plate 1 moves along the fifth direction of the Z-axis; when the connecting end of the lifting linear actuator 41 retracts, the positioning plate 1 moves along the sixth direction of the Z-axis. In practical applications, the sixth direction is opposite to the fifth direction, and the sixth direction, the fourth direction, and the second direction are perpendicular to each other. Furthermore, in the initial state, the extension length of the cylinder rod (or piston rod) of the lifting linear actuator 41 is half of the range of the lifting linear actuator 41.

[0077] In some preferred embodiments, the lifting frame includes a plurality of telescopic rods 423 and a first support plate 421 and a second support plate 422 disposed opposite to each other. Specifically, the first support plate 421 is connected to the cylinder of the lifting linear actuator 41, the second support plate 422 is connected to the connecting end of the lifting linear actuator 41, and the first end of each telescopic rod 423 is connected to the first support plate 421, and the second end of each telescopic rod 423 is connected to the second support plate 422. In application, the first support plate 421 is mounted on the bracket of the rotating part 5. Further, each telescopic rod 423 includes a first rod and a second rod, the first end of the first rod is connected to the first support plate 421, the second end of the first rod is telescopically inserted into the first end of the second rod, and the second end of the second rod is connected to the second support plate 422. Further still, to prevent the first rod from slipping off the second rod, each telescopic rod 423 of the present invention includes a snap-fit ​​structure (not shown). For example, the snap-fit ​​structure includes a first ring (not shown) with a groove and a second ring (not shown) with a protrusion matching the groove. Specifically, a first ring with a groove is disposed on the second end of the first rod, and a second ring with a protrusion matching the groove is disposed on the first end of the second rod. In application, when the connecting end of the lifting linear actuator 41 extends outward and the groove of the first ring engages with the protrusion of the second ring, due to the limiting effect of the snap-fit ​​structure, even if the connecting end of the lifting linear actuator 41 continues to be pushed outward, the connecting end of the lifting linear actuator 41 will not continue to extend outward, and the positioning plate 1 will not continue to move along the fifth direction of the Z-axis. When the connecting end of the lifting linear actuator 41 retracts, after the first rod is fully inserted into the second rod, due to the limiting effect of the first support plate 421 and the second rod, even if the connecting end of the lifting linear actuator 41 continues to be pulled back, the connecting end of the lifting linear actuator 41 will not continue to retract inward, and the positioning plate 1 will not continue to move along the sixth direction of the Z-axis. In practical applications, to fully utilize the lifting linear actuator 41, the length of the first rod is greater than half the range of the lifting linear actuator 41.

[0078] The rotating part 5 of the present invention drives the positioning plate 1 to rotate clockwise or counterclockwise around the Z-axis in the XOY plane.

[0079] refer to Figure 3 To improve the accuracy and stability of rotation, the rotating part 5 of the present invention includes a slewing bearing 52, a worm gear (not shown), and a hydraulic motor 51. Furthermore, to ensure the smoothness and reliability of the rotation process, the rotating part 5 of the present invention may also include a motor adjusting block (not shown).

[0080] In some preferred embodiments, a hydraulic motor 51 drives a worm gear, which is coupled to a slewing bearing 52, which is connected to a first support plate 421. In application, the slewing bearing 52 has opposing third and fourth sides. The third side of the slewing bearing 52 is mounted on a base 6, and the fourth side of the slewing bearing 52 is connected to the first support plate 421. In practical applications, the hydraulic motor 51 can rotate clockwise or counterclockwise. The hydraulic motor 51 drives a motor adjusting block, which is connected to the worm gear, causing the worm gear to rotate uniformly clockwise or counterclockwise in the ZOY plane. The worm gear then drives the slewing bearing 52 to rotate clockwise or counterclockwise in the XOY plane, so that the positioning plate 1 rotates clockwise or counterclockwise around the Z-axis in the XOY plane.

[0081] In order to better utilize the form and position adjustment mechanism 100 and ensure that the scanned object can be accurately aligned with the scanning area during the scanning process, and to avoid image blurring caused by positional deviation, the present invention also describes the method of using the form and position adjustment mechanism 100.

[0082] The methods of using the form and position adjustment mechanism 100 include SS11-SS17.

[0083] SS11 Confirm Mechanism Status: Ensure that the position adjustment mechanism 100 and its components (e.g., fine-tuning assembly, translation assembly, lifting part 4, rotating part 5, etc.) are in good working condition and free from damage or abnormalities.

[0084] SS12 Installation of the object to be scanned: Fix the object to be scanned on the positioning plate 1, ensuring that it is firmly fixed to avoid movement or deformation during the scanning process.

[0085] SS13 connects the power supply and control system: connect the positioning adjustment mechanism 100 to the power supply and perform initialization settings through the control system to ensure that the control system can normally control the movement of each component.

[0086] SS14 Rotation Adjustment: Start the hydraulic motor 51 of the rotating part 5 to drive the worm gear to rotate, which in turn drives the slewing bearing 52 to rotate, so that the positioning plate 1 can rotate clockwise or counterclockwise around the Z-axis in the XOY plane to the required angle.

[0087] SS15 Lifting Adjustment: Start the lifting linear actuator 41 of the lifting unit 4, drive the translation unit 3 (or directly drive the positioning plate 1) through the connecting end, so that the positioning plate 1 moves back and forth along the Z-axis direction to the required Z-axis position.

[0088] SS16 Translation Adjustment: If translation along the Y-axis is required, activate the first telescopic linear actuator 312 of the first translation component to move the positioning plate 1 back and forth along the Y-axis to the desired Y-axis position. If translation along the X-axis is required, activate the second telescopic linear actuator 322 of the second translation component to move the positioning plate 1 back and forth along the X-axis to the desired X-axis position.

[0089] SS17 Fine-tuning Positioning: If further adjustment of the coordinate accuracy of the positioning plate 1 is required, the first fine-tuning component is used. By rotating the motor and driving the damper, the first fold line 101 of the positioning plate 1 is reciprocated around the second fold line 102 in the Y-axis direction until the actual coordinate of the positioning plate 1 on the Y-axis equals the preset coordinate of the Y-axis. Using the second fine-tuning component, by rotating the motor and driving the damper, the second fold line 102 of the positioning plate 1 is reciprocated around the first fold line 101 in the X-axis direction until the actual coordinate of the positioning plate 1 on the X-axis equals the preset coordinate of the X-axis. To improve the tolerance for changes in the height of the scanned component, the scanning device of the present invention includes: the above-described shape and position adjustment mechanism 100, the CT scanning unit 800, and the lifting assembly 700.

[0090] refer to Figure 4 and Figure 5 The lifting assembly 700 has its first end connected to the mounting platform and its second end connected to the CT scanning unit 800. The scanning area of ​​the CT scanning unit 800 corresponds to the external position of the object to be scanned, which is abutted by the positioning adjustment mechanism 100. The scanning area can be a scanning cavity that extends vertically. In application, during scanning, the CT scanning unit 800 is fitted around the periphery of the positioning adjustment mechanism 100, which can extend into the scanning cavity of the CT scanning unit 800. Furthermore, after the positioning adjustment mechanism 100 adjusts the position of the object to be scanned or the positioning plate 1 from six degrees of freedom, the lifting assembly 700 can also be used to adjust the position of the CT scanning unit 800 in the Z-axis direction (vertical direction) to achieve precise tomographic scanning of the object to be scanned. In practical applications, to save installation space, improve safety, and enhance the visual appeal of the facility, the CT scanning unit 800 is installed horizontally and raised from the bottom during use.

[0091] In some preferred embodiments, the lifting assembly 700 of the present invention includes multiple lifting modules (not shown). Preferably, the lifting assembly 700 of the present invention includes two lifting modules, which are symmetrically arranged.

[0092] Each lifting module includes at least one telescopic linear actuator (not shown). Further, each lifting module includes a fixed plate (not shown) and an extension plate (not shown). Specifically, the cylinder of the telescopic linear actuator is connected to the fixed plate, the connecting end of the telescopic linear actuator is connected to the extension plate, and the extension plate is connected to the CT scanning unit 800. In application, the telescopic linear actuator is activated, driving the extension plate and the CT scanning unit 800 to reciprocate along the Z-axis. In actual application, initially, the extended length of the cylinder rod (or piston rod) of the telescopic linear actuator is half the range of the telescopic linear actuator.

[0093] In some preferred embodiments

[0094] In order to better utilize the scanning device and ensure that the object to be scanned can be accurately aligned with the scanning area during the scanning process, and to avoid image blurring caused by positional deviation, the present invention also describes a method for using the scanning device.

[0095] The methods of using the scanning device include: SS21-SS23.

[0096] SS21 installs the positioning adjustment mechanism 100 into the scanning device and ensures that it is aligned with the CT scanning unit 800.

[0097] The SS22 adjusts the shape and position adjustment mechanism 100 to place the object to be scanned within the scanning range of the CT scanning unit 800.

[0098] The SS23 starts the CT scanning unit 800 to perform a scanning operation and makes adjustments and optimizations based on the scanning results.

[0099] The medical device of the present invention includes: the scanning device (not shown) described above and a control system (not shown). The control system controls the positioning adjustment mechanism 100 and the lifting assembly 700. The medical device may be a medical imaging device, such as a CT imaging device, and the scanning device may include a CT scanning unit, which includes an X-ray tube.

[0100] Based on scanning requirements, the control system can achieve six-axis linkage, including fine adjustment, translation, lifting, rotation, tilting forward and backward, and swaying left and right, to precisely adjust the position and orientation of the workpiece to be scanned. Furthermore, during operation, the control system can monitor the real-time running status of the form and position adjustment mechanism 100.

[0101] In order to better utilize medical equipment and ensure that the object to be scanned can be accurately aligned with the scanning area during the scanning process, and to avoid image blurring caused by positional deviation, this invention also describes a method for using the medical equipment.

[0102] The usage methods for medical equipment include: SS31-SS33.

[0103] In the control system of the medical equipment, SS31 sets up and starts the linkage program between the positioning adjustment mechanism 100 and the lifting assembly 700.

[0104] The SS32 adjusts the position and orientation of the positioning mechanism 100 according to the scanning requirements and the patient's condition.

[0105] The SS33 monitors the scanning process to ensure scan quality and patient safety.

[0106] In summary, by providing the adjustment part 2, translation part 3, lifting part 4 and / or rotation part 5, the present invention enables the positioning plate 1 to not only move and adjust in the X and Y axis directions, but also translate in these two directions, lift in the Z axis direction, and rotate in the XOY plane (i.e., rotate around the Z axis). This greatly expands the application range of the form and position adjustment mechanism 100, enabling it to meet the needs of more complex scanning scenarios, especially in vertical CT scanning equipment.
