Description
Technical Field
[0001] The invention relates to the technical field of medical devices, and in particular to an X-ray protection device suitable for peripheral interventional surgery. Background Art
[0002] X-rays, as electromagnetic waves with extremely short wavelengths and strong penetrating power, are widely used in the medical field for auxiliary examinations. However, when X-rays are irradiated to biological organisms, they will have a significant inhibitory effect on biological cells, and even cause cell damage and necrosis, which will in turn cause varying degrees of changes in the body at multiple levels such as physiology, pathology, and biochemistry. Long-term or high-intensity X-ray radiation exposure poses a serious threat to the health of patients and medical staff, specifically manifested in possible skin damage, hematopoietic dysfunction, eye damage, and other hazards, and there is a risk of inducing cancer and genetic diseases.
[0003] Although current X-ray protection technology has made certain progress, traditional personal protective equipment such as lead suits and lead aprons can reduce the hazards of X-ray radiation to a certain extent, but their protective effects are still limited and cannot completely eliminate the potential effects of radiation. Especially in peripheral interventional surgery, if medical staff need to frequently perform X-rays to monitor the progress of the operation, they have to manually adjust the position of protective equipment to ensure adequate protection for patients and themselves. However, this frequent manual adjustment is not only cumbersome to operate, but may also lead to omissions in protection, exposing some areas to X-rays. In view of the above problems, it is particularly important to develop a device that can adapt to the needs of peripheral interventional surgery and realize automated X-ray protection. The device can simplify the operating steps of multiple X-rays, and through intelligent and automated technical means, ensure comprehensive and continuous protection of patients and medical staff during the operation, thereby reducing the health risks caused by X-ray radiation. Summary of the invention
[0004] To solve the above problems, the present invention provides an X-ray protection device suitable for peripheral interventional surgery. Through intelligent surgical process design and regional selected X-ray irradiation, it ensures comprehensive and continuous protection for patients and medical staff during the operation and reduces the health risks caused by X-ray radiation.
[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an X-ray protection device suitable for peripheral interventional surgery, comprising an X-ray irradiator and a lifting operating table, one end of the operating table is fixedly connected to a driving box, the top surface of the operating table is fixedly connected to reels on all sides, a protective blanket and a stretching assembly for elastically stretching the protective blanket are arranged in the reels, a hoop for tightening the protection and having an adjustable area is also arranged above the operating table, a plurality of protective blankets are fixedly connected to the hoop, and first connecting rods are fixedly connected to both sides of the hoop;
[0006] A servo motor is fixedly connected to the driving box, and the servo motor signal is connected to a control system for receiving and transmitting signals. A threaded rod is coaxially fixedly connected to the servo motor output shaft, and a displacement block is sleeved on the threaded rod, and the displacement block is threadedly connected to the threaded rod. A sliding box corresponding to the movement trajectory of the displacement block is fixedly connected to the bottom surface of the operating table, and a displacement block is arranged in the sliding box, and the displacement block and the sliding box are slidably matched. The sliding box is connected to the stretching assembly, and symmetrical through grooves are opened on both side walls of the sliding box. Second connecting rods corresponding to the through grooves are fixedly connected to both side walls of the displacement block, and the second connecting rods extend to both sides of the operating table. A connecting assembly for driving the displacement of a hoop is provided at one end of the second connecting rod away from the displacement block, and the connecting assembly is fixedly connected to the end of the corresponding first connecting rod away from the hoop.
[0007] The technical principle of the above scheme is as follows: a servo motor is designed as a power source. When the servo motor is started, it will drive the threaded rod to rotate. At the same time, the displacement block will move linearly along the axial direction of the threaded rod. The design of the sliding box ensures that the displacement block can remain stable and smooth during the movement. The displacement block is connected to the connecting assembly through the second connecting rod. When the displacement block moves, the second connecting rod will drive the connecting assembly to move accordingly. Correspondingly, the hoop is connected to the connecting assembly through the first connecting rod. The area covered by the hoop serves as a special area for X-ray irradiation.
[0008] The above scheme has the following beneficial effects:
[0009] 1. In this solution, through the precise control of the servo motor and the threaded rod, the X-ray protection device can achieve fast and precise lateral corresponding displacement, thereby improving the specificity of surgical X-ray irradiation. The servo motor has high-precision control capabilities and fast response speeds, and the signal connection between the servo motor and the control system ensures that the rotational movement of the threaded rod can be carried out according to the preset program or instructions. When a certain area needs to be irradiated, the servo motor drives the threaded rod to rotate, and the displacement block on the threaded rod moves axially accordingly, and drives the connecting assembly and the hoop to move toward the specified position through the second connecting rod. The smooth and continuous displacement process can enable the hoop to quickly cover the area that needs X-ray irradiation in a short time, provide specific X-rays to patients, and provide protection for other areas at the same time, thereby improving the protection efficiency during surgery.
[0010] 2. In this scheme, due to the different body shapes of patients, in actual application, the body shape differences of patients may lead to different needs for X-ray protection. Fat patients may have higher skin surface, while thin patients have lower skin surface height than fat patients. By designing an elastic stretching component connected with the hoop, the protective blanket can adapt to various body surface heights and fit closely to the body surface of different surgical patients, so as to reduce radiation leakage and unnecessary refraction exposure and improve the adaptability of surgery.
[0011] 3. Since surgical conditions are complex and changeable, and surgical sites are also different, it is often necessary to shoot areas of different sizes. Therefore, this solution designs a hoop with an adjustable area. This design greatly improves the adaptability of the surgery. During the operation, medical staff can adjust the area of the hoop according to actual needs, thereby accurately controlling the area that needs to be exposed to X-ray irradiation, ensuring the accuracy and safety of X-ray irradiation, and ensuring comprehensive and continuous protection of patients and medical staff during the operation.
[0012] 4. In this solution, the application of the control system in the X-ray protection device brings significant advantages compared to traditional manual control. First, it enables the operator to control the position of the hoop and the deployment of the protective blanket through simple instructions or preset programs, which greatly simplifies the operation process and reduces the difficulty of operation. In the traditional manual control mode, the operator needs to personally adjust the mechanical parts, such as rotating the handle, pushing the slider, etc., which is not only time-consuming and laborious, but may also cause inaccurate or unstable operation due to human factors. The intelligent control system uses precise algorithms and sensor feedback to achieve real-time monitoring and adjustment of the position of the hoop and the protective blanket to ensure the accuracy and stability of the operation.
[0013] 5. On the other hand, in X-ray protection devices adapted to peripheral interventional surgery, in order to ensure excellent protection effects, the protective blanket needs to be in close contact with the skin surface of the surgical patient. However, during the entire X-ray filming process, due to the need for tight full coverage and the possibility of multiple shots, the patient's body is covered for a long time, which may lead to a lack of ventilation in the covered area and cause discomfort to the patient. In this solution, by designing a connection mechanism between the sliding box and the stretching assembly, when the displacement block moves in the sliding box, that is, when the X-ray filming position changes, the movement of the displacement block not only drives the precise positioning of the hoop and the protective blanket, but also changes the gas volume in the front and back of the sliding box, thereby achieving gas exchange between the external gas and the stretching assembly and the covered position of the protective blanket, ensuring that the patient's skin in the covered area can get the necessary ventilation, effectively reducing the patient's discomfort.
[0014] Furthermore, the stretching components include a rotating shaft rotatably connected to the reel, a plurality of springs are fixedly connected to the side walls of the rotating shaft, the inner ends of the springs are fixedly connected to the side walls of the rotating shaft, and the outer ends of the springs are fixedly connected to the protective blanket.
[0015] Beneficial effect: The design of the spring allows the protective blanket to maintain a certain tension state when no external force is applied. When the protective blanket needs to be unfolded, it is only necessary to overcome the initial resistance of the spring, and the protective blanket will automatically unfold as the shaft rotates, without the need for additional driving force. Therefore, when the hoop is moved, the four-way protective blanket can be freely extended or retracted, ensuring that the protective blanket can remain flat and uniform during the unfolding process, avoiding wrinkles or looseness caused by uneven stretching, and helping the protective blanket to fit tightly to the operating table or the patient, reducing radiation leakage and improving the protective effect.
[0016] Furthermore, the hoop includes two parallel and symmetrical fixed tubes, the outer side walls of the fixed tubes are vertically fixedly connected to the corresponding first connecting rods, two telescopic tubes are arranged between the two fixed tubes, and both ends of the telescopic tubes are fixedly connected to the fixed tubes on both sides.
[0017] Beneficial effects: The design of the telescopic tube gives the hoop the flexibility of area control, which not only improves the adaptability of the system, but also ensures that the hoop can fit the target area closely, reducing radiation leakage and unnecessary exposure. At the same time, due to the signal connection between the electric telescopic rod and the control system, the entire adjustment process can be automated and intelligent, greatly improving the operating efficiency and accuracy.
[0018] Furthermore, the connecting components include a control box body fixedly connected to the second connecting rod, and a rotating groove is opened on the side wall of the control box body close to the operating table. An electric telescopic rod is hinged in the rotating groove, and the electric telescopic rod is connected to the control system signal. The output end of the electric telescopic rod is fixedly connected to the corresponding first connecting rod.
[0019] Beneficial effects: Since the doctor's attention is on the patient during the operation, the introduction of intelligently controlled connection components and the signal connection between the electric telescopic rod and the control system realize intelligent control of the hoop position, which improves the convenience of operation. The precise movement of the electric telescopic rod ensures that the hoop can be stably fixed, thereby improving the reliability and efficiency of the entire system and improving the safety of the operation.
[0020] Furthermore, a limit plate is fixedly connected in the rotating groove, and a fixed limit block is sleeved on the output end of the electric telescopic rod. The inclination of the limit block close to one end of the electric telescopic rod is greater than the inclination away from one end of the electric telescopic rod.
[0021] Beneficial effect: Since the closer the body of the same patient is to the central axis, the higher the skin surface height is, therefore, by designing the electric telescopic rod with variable inclination, the electric telescopic rod can be effectively tilted upward when extended to better fit the patient's body curve, avoiding the sudden impact that may be caused by traditional linear motion, and ensuring that the hoop can be stably and accurately fixed in the target area, thereby improving surgical efficiency and reducing operating difficulty and error rate.
[0022] Furthermore, the first connecting rod, the telescopic cylinder and the fixed cylinder are all made of elastic material, and the bottoms of the telescopic cylinder and the fixed cylinder are fixedly connected with an elastic layer.
[0023] Beneficial effects: Traditional hard materials are often difficult to fit perfectly, which not only affects the accuracy of the surgery, but may also increase the discomfort of the patient. Therefore, this solution uses elastic materials to make these parts, and adheres and fixes the elastic layer to the bottom of the telescopic tube and the fixed tube. Through the flexibility and adaptability of the elastic material, the hoop can fit the patient's skin more closely, regardless of how the patient's body shape changes. When the hoop contacts the patient's skin, the elastic layer can undergo slight deformation to adapt to the contour and height changes of the patient's skin, which not only helps to reduce the patient's discomfort, but also ensures the accuracy of X-ray irradiation, because the close fit of the hoop can reduce the scattering and leakage of X-rays, thereby reducing unnecessary radiation exposure.
[0024] Furthermore, a plurality of elastic first protective blocks are hinged at the bottom of the operating table, and a second protective block with a semicircular structure is fixedly connected to the side of the control box away from the operating table.
[0025] Beneficial effects: In complex and delicate surgical procedures, especially those involving X-ray irradiation, it is crucial to ensure the safety of patients and surgical personnel. When the position or angle of the X-ray irradiator needs to be adjusted frequently during surgery, and the operation of the surgical instrument may interfere with the original first protective block, the second protective block can be automatically or manually dropped to assume the protective function that the flipped first protective block should have, ensuring that even if the first protective block fails, patients and surgical personnel can still receive effective radiation protection.
[0026] Furthermore, a plurality of air grooves corresponding to the through grooves are formed on the top wall of the sliding box, and one end of the air groove away from the through grooves passes through the operating table and is connected with the reel.
[0027] Beneficial effect: The setting of the air groove increases the air circulation path inside the sliding box. During the operation of the machine, especially when the reel rotates or the internal components generate heat, the air groove can effectively guide the air flow, help dissipate heat, prevent overheating, and thus extend the service life of the equipment.
[0028] Further, the control system includes a receiving module, a processing module and a driving module;
[0029] A receiving module, used for receiving the irradiation position information input by the operator, and transmitting the irradiation position information to the processing module;
[0030] A processing module is used to convert the irradiation position information into target coordinate data, compare the current coordinate data of the X-ray irradiator with the target coordinate data, and convert them into driving power signals of the servo motor and a plurality of electric telescopic rods, and transmit each driving power signal to the driving module;
[0031] The driving module is used to receive the driving power signal and correspondingly drive and control the servo motor and a plurality of electric telescopic rods.
[0032] Beneficial effects: The irradiation position information input by the operator is received by the receiving module and converted into target coordinate data by the processing module, thereby realizing precise positioning control of the X-ray irradiator; the position information is automatically converted into a driving power signal by the processing module, thereby reducing the complexity of manual operation and improving the level of automation; the servo motor and the electric telescopic rod are driven in real time by the driving module according to the driving power signal transmitted by the processing module, thereby ensuring a rapid response to the irradiation position.
[0033] Furthermore, in the processing module, the current coordinate data and the target coordinate data are processed in the form of x1, y1 and x2, y2 respectively, and the difference between y1 and y2 is used as the direction of rotation driven by the servo motor. When the difference is a positive number, the servo motor is driven to rotate clockwise, and when the difference is a negative number, the servo motor is driven to rotate counterclockwise. The difference between x1 and x2 is used as the extension and retraction drive of the electric telescopic rods symmetrical at both ends.
[0034] Beneficial effects: By processing the coordinate data in the form of (x, y), the target position can be accurately described and positioned, which not only improves the accuracy of the system, but also makes the operation more intuitive and easy to understand. In addition, the difference between y1 and y2 is used as the direction of rotation of the servo motor to achieve precise control of the motor rotation. When the difference is positive, the motor rotates clockwise; when the difference is negative, the motor rotates counterclockwise, so that the motor can flexibly adjust the rotation direction according to the change of the target position, thereby ensuring that the reel or related components can accurately reach the specified position.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0046] The following is further described in detail through specific implementation methods:
[0047] Embodiment 1:
[0048] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown: an X-ray protection device suitable for peripheral interventional surgery, including an X-ray irradiator 2 and a liftable operating table 1, the X-ray irradiator 2 includes a receiving end, an irradiating end and a connecting seat, the connecting seat is placed on one side of the operating table 1, the receiving end and the irradiating end are fixedly connected to form an integrated semicircular structure through the connecting seat, the receiving end is located above the operating table 1, and the irradiating end is located below the bed board of the operating table 1.
[0049] The top surface of the operating table 1 is fixedly connected to the reels 4 on all sides. Take one of the reels 4 as an example. Figure 3 As shown, a protective blanket 5 and a rotating shaft 14 are arranged in the reel 4, and the rotating shaft 14 is rotatably connected to the reel 4 through a bearing. A plurality of springs 15 are arranged on the side wall of the rotating shaft 14, and the inner ends of the springs 15 are welded to the side wall of the rotating shaft 14, and the outer ends of the springs 15 are fixedly connected to the protective blanket 5 through rivets. A hoop 6 for tightening the protective blanket 5 is also arranged above the operating table 1, and the other end of the protective blanket 5 is fixedly connected to the hoop 6 through a screw. The combination of the reel 4 and the protective blanket 5 arranged in four directions can realize that only the part within the hoop 6 is exposed, and the range from the hoop 6 to the surrounding reel 4 can be covered by the protective blanket 5, thereby achieving the purpose of specific protection for the patient; during the X-ray irradiation process, by adjusting the position of the hoop 6, the area that needs to be exposed to the X-ray irradiation can be flexibly controlled, which effectively reduces unnecessary radiation exposure, protects the non-examination part of the patient from X-ray damage, and improves the accuracy and safety of the examination.
[0050] Specific as Figure 2As shown, a driving box 3 is welded at one end of the operating table 1, and a servo motor 7 is fixedly connected to the driving box 3 by bolts. The output shaft of the servo motor 7 is coaxially fixedly connected to a threaded rod 8 through a coupling. A displacement block 9 is sleeved on the threaded rod 8, and the displacement block 9 is threadedly connected to the threaded rod 8. The design of the threaded connection between the displacement block 9 and the threaded rod 8 makes it possible for the output shaft of the servo motor 7 to drive the threaded rod 8 to rotate through the coupling when the servo motor 7 is started, and a sliding box 10 corresponding to the motion trajectory of the displacement block 9 is welded to the bottom surface of the operating table 1, and the inner wall of the sliding box 10 is slidably matched with the outer wall of the displacement block 9. Through the setting of the sliding box 10, the movement of the displacement block 9 that originally rotates forward with the threaded rod 8 is subject to rotational limitation, which is reflected as displacement forward and backward along the sliding box 10, and the forward displacement or backward displacement is controlled by the forward and reverse rotation of the servo motor 7.
[0051] The servo motor 7 is also connected to the control system by signal, and symmetrical through grooves 11 are provided on both side walls of the sliding box 10, and second connecting rods 13 corresponding to the through grooves 11 are welded to both side walls of the displacement block 9, and the second connecting rods 13 extend to both sides of the operating table 1 and are fixedly connected to the control box 16. Through the signal control of the control system, the front and rear distance of the displacement block 9, that is, the displacement along the body length direction after the patient lies on the operating table 1, can be accurately controlled, and an intelligent control process can be realized, providing a driving basis for the subsequent position control of the hoop 6.
[0052] In addition, the sliding box 10 is provided with a plurality of air grooves 24, which correspond to the positions of the reel 4. The air grooves 24 are provided at the top of the sliding box 10 and pass through the operating table 1 to be in corresponding communication with the reel 4. For example, when the displacement block 9 moves forward, the displacement block 9 compresses the space in the front of the sliding box 10, so that the front gas is squeezed out and flows into the reel 4 through the air grooves 24, and escapes through the reel 4 to the area covered by the protective blanket 5. At the same time, the space in the rear of the sliding box 10 is correspondingly expanded, and fresh air from the outside is sucked in to realize gas exchange, which is conducive to reducing the discomfort of the patient due to being covered by the protective blanket 5 for a long time.
[0053] Specifically, take the control box 16 on one side as an example, see Figure 3 A rotating groove 17 is provided on the side wall of the top of the control box 16 near the operating table 1. A spherical hinge ball block is hinged in the rotating groove 17. An electric telescopic rod 18 is fixedly connected to the spherical hinge ball block by bolts. The design of the rotating groove 17 and the spherical hinge ball block allows the electric telescopic rod 18 to move flexibly in three-dimensional space. In addition, the combination of the spherical hinge ball block and the rotating groove 17 allows a certain angle deviation and adaptive adjustment, which to a certain extent compensates for the slight errors that may occur in the mechanical installation and operation, as well as the differences in the patient's body shape, so that the height of the hoop 6 can be adapted to patients of different body shapes, further improving the overall accuracy and reliability of the system.
[0054] Since the hoop 6 includes a plurality of symmetrical fixed cylinders 601 and telescopic cylinders 602, as shown in FIG. Figure 6 As shown, a plurality of fixed tubes 601 and telescopic tubes 602 are fixedly connected to each other to form a rectangular frame. The outer wall of each fixed tube 601 is vertically welded with a first connecting rod 12, and the electric telescopic rod 18 is connected to the control system signal. The output end of the electric telescopic rod 18 is fixedly connected to the first connecting rod 12 through a coupling. Through the design of the rotating groove 17 and the spherical hinge ball block, when the electric telescopic rod 18 is extended or shortened, the telescopic tube 602 can be extended or shortened accordingly, thereby controlling the area of the hoop 6. This design enables the hoop 6 to flexibly adapt to target areas of different sizes. Through the precise control of the control system, the electric telescopic rod 18 can perform fast and accurate telescopic actions as needed. When the electric telescopic rod 18 is extended, it will push the first connecting rod 12 through the coupling, and then drive the telescopic tube 602 connected to the fixed tube 601 to expand outward, thereby increasing the area of the hoop 6. On the contrary, when the electric telescopic rod 18 is shortened, it will pull the first connecting rod 12, causing the telescopic tube 602 to shrink inward, thereby reducing the area of the hoop 6.
[0055] The side wall of the control box 16 is provided with a limit plate 19 located at the opening of the rotation groove 17. Figure 4 As shown, a fixed limit block 20 is sleeved on the output end of the electric telescopic rod 18, and the inclination of the limit block 20 close to the end of the electric telescopic rod 18 is greater than the inclination of the end away from the electric telescopic rod 18. The cooperation between the limit block 20 and the limit plate 19 constitutes a limiting mechanism for the inclination angle, so that the size of the limit inclination determines the size of the inclination of the electric telescopic rod 18. When the electric telescopic rod 18 is extended or shortened, if an attempt is made to exceed the inclination angle set by the limit block 20 and the limit plate 19, the limit block 20 will interfere with the limit plate 19, thereby preventing the electric telescopic rod 18 from further tilting, ensuring that the electric telescopic rod 18 can maintain a relatively stable posture during operation, avoiding problems such as inaccurate positioning or protection failure due to excessive tilting.
[0056] Embodiment 2:
[0057] As attached Figure 6 As shown, the difference from Example 1 is that the first connecting rod 12, the telescopic tube 602 and the fixed tube 601 are all elastic, and the bottom of the telescopic tube 602 and the fixed tube 601 are adhered and fixed with an elastic layer 21. When the fixed rod and the telescopic rod contact the patient's skin surface, firstly, the use of elastic material can ensure that the hoop 6 can provide better comfort and fit when it fits the patient's skin. Since surgical patients have different body shapes, the skin height of the patients is different when they lie flat. The design of the elastic layer 21 can more easily adapt to patients of different body shapes, so that the hoop 6 can fit the target area more closely, thereby improving the accuracy of X-ray irradiation and reducing unnecessary radiation exposure.
[0058] Embodiment 3:
[0059] As attached Figure 1 As shown, the difference from Example 2 is that a plurality of elastic first protective blocks 22 are hinged at the bottom of the operating table 1, and a second protective block 23 with a semicircular structure is fixedly connected to the side of the control box 16 away from the operating table 1. Since the emitting end of the X-ray irradiator 2 is placed at the bottom of the operating table 1, and during the operation, there may be a situation where the surgeon changes from performing an X-ray examination to performing an operation. When the second connecting rod 13 moves and the first protective block 22 is folded and turned up and fails, the second protective block 23 can fall down and assume the protective effect that the turned-up first protective block 22 should have, ensuring that during the operation, even if the first protective block 22 is temporarily turned up or fails for some reason (such as adjustment of the hoop 6, operation of surgical instruments, etc.), the patient and the surgeon can still get effective radiation protection.
[0060] Embodiment 4:
[0061] As attached Figure 1 As shown, the difference from Example 3 is that the reel 4 on the side away from the servo motor 7 is an elastic reel 4, and the two ends of the reel 4 are respectively hinged to the two sides of the operating table 1. Considering the process of the patient lying on the operating table 1 and the side away from the servo motor 7 is the patient's body, in order to improve the integrity of the protection blanket 5 during the process, a special reel 4 is designed to ensure that when the patient lies on the operating table 1, the reel 4 can be smoothly unfolded and fit the patient's body curve without causing pressure or discomfort to the patient.
[0062] Embodiment 5:
[0063] The difference from Example 4 is that the control system includes a receiving module, a processing module and a driving module;
[0064] The receiving module receives the irradiation position information input by the operator and transmits the irradiation position information to the processing module.
[0065] The processing module converts the irradiation position information into target coordinate data, and compares the current coordinate data of the X-ray irradiator 2 with the target coordinate data, and processes the current coordinate data and the target coordinate data in the form of x1, y1 and x2, y2 respectively. The difference between y1 and y2 is used as the direction of the servo motor 7 to drive the rotation. When the difference is a positive number, the servo motor 7 is driven to rotate clockwise, and when the difference is a negative number, the servo motor 7 is driven to rotate counterclockwise. The difference between x1 and x2 is used as the extension and contraction drive of the electric telescopic rod 18 symmetrical at both ends. When x1 is less than x2, it means that the current position of the X-ray irradiator 2 is on the left side of the target position. The processing module will send an instruction to the electric telescopic rod 18 controller to extend the left electric telescopic rod 18 and contract the right electric telescopic rod 18, thereby pushing the hoop 6 and the X-ray irradiator 2 thereon to move rightward in the horizontal direction. On the contrary, if x1 is greater than x2, the processing module will instruct the right electric telescopic rod 18 to extend and the left electric telescopic rod 18 to contract, so that the X-ray irradiator 2 moves leftward. In addition, the area of the hoop 6 can be controlled by controlling the different extension amounts of the electric telescopic rods 18 on both sides, so as to adapt to the characteristics of peripheral interventional surgery and perform X-ray irradiation on a specific position.
[0066] The driving module receives the driving power signal and drives and controls the servo motor 7 and a plurality of electric telescopic rods 18 accordingly.
[0067] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
