Description
Technical Field
[0001] The present invention relates to the technical field of radiology, and more specifically, to a radiation shield for clinical use in radiology. Background Art
[0002] In the modern medical field, the radiology department plays a crucial role. The radiology department mainly uses various ray devices to diagnose and treat patients. During the radiotherapy process, it is crucial to precisely control the irradiation range of the rays to ensure that while effectively treating the diseased area, the damage to normal tissues is minimized to the greatest extent.
[0003] Currently, when performing radiotherapy in existing radiology departments, a shielding plate is usually used for auxiliary protection. Although this shielding plate can block the rays to a certain extent and prevent them from irradiating normal tissues, it has obvious limitations. First of all, the size of the shielding plate is single and cannot be flexibly adjusted at the ray slot for treatment on the inner side of the shielding plate according to specific treatment requirements. When the ray range is small, the slot cannot be effectively narrowed, which may result in excessive normal tissues being exposed to the rays, increasing unnecessary radiation risks.
[0004] Secondly, when performing radiotherapy on patients with the existing shielding plate, it cannot be adjusted to shield the side of the patient. When radiotherapy is required on the side of the patient, the existing shielding plate is obviously unable to be flexibly adapted. This not only reduces the accuracy of radiotherapy but also may cause unnecessary radiation damage to other normal parts of the patient, affecting the treatment effect and the patient's recovery process. Therefore, in order to improve the accuracy and safety of radiotherapy, there is an urgent need for a new type of radiology protection device that can overcome the deficiencies of the existing shielding plate.

[0020] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:
[0021] In the above solution, through the cooperation of the displacement device and the adjustment device, during use, the second motor can be started to drive the first gear to rotate. Since the first gear meshes with the arc-shaped rack, the arc-shaped slide plate can be driven to slide along the arc-shaped track, so that the baffle device can be displaced along the arc to adapt to the radiotherapy of the patient's side position. At the same time, the third motor is started to drive the second gear to rotate. With the meshing connection with the straight rack, the reaction force drives the sliding block to slide in the transverse track, and then the position of the baffle device above the patient on the bed body can be flexibly adjusted. In this way, the device can not only adjust the baffle device in a circular displacement, but also perform a linear displacement adjustment, which maximally meets the different needs of the patient's radiotherapy and improves the overall adaptability of the equipment.
[0022] By setting the baffle mechanism, during use, the first motor at the rear side of the side rail can be started to drive the screw rod inside the side side rail to rotate. Since the thread directions at both ends of the screw rod are opposite, the movable blocks can be synchronously driven to slide at both ends of the side rail, and then the upper connecting frame is driven to drive the transverse baffle to displace horizontally. At the same time, the rotation of the screw rod drives the first bevel gear and the second bevel gear to drive each other, so that the screw rod inside the front side rail rotates, driving the front movable block to slide, and driving the lower connecting frame to drive the longitudinal baffle to displace back and forth. In this way, the operation of one first motor can synchronously drive the transverse baffle and the longitudinal baffle to reciprocate and displace. This efficient synchronous drive design makes it more convenient to adjust the baffle and improves the operation efficiency.
[0023] By setting the displacement device, the adjustment device and the baffle device to cooperate with each other, the device can not only adjust the position of the baffle device, but also adjust its size. By adjusting the transverse baffle and the longitudinal baffle to expand outward, the notch between the two inside the frame can be enlarged; by contracting and combining, the notch can be reduced. It can be seen that the device only needs to operate one first motor to quickly control the baffle notch. This design enables the device to better adapt to different radiotherapy scenarios. Whether it is for treatment areas of different sizes or different parts of the patient's body at different positions, accurate shielding can be carried out, which improves the practicability and adaptability of the equipment and brings more convenience and safety guarantee for the patient's radiotherapy.
[0024] By activating the electric push rod, the bending connecting pipe can be pushed to move up and down, thereby driving the shielding auxiliary plate to move up and down, assisting in shielding the adjustment gap outside the shielding plate group, improving the comprehensiveness of shielding. At the same time, when the fourth motor is activated, the first motor drives the threaded rod to rotate, enabling the slider to slide within the guide rail, thereby adjusting the lateral displacement of the shielding auxiliary plate inside the slider so that it can follow the displacement of the shielding plate group to achieve comprehensive shielding. During the shielding process, the electric push rod can push the shielding auxiliary plate to adaptively adjust according to different adjustment states of the shielding plate group, playing a comprehensive protection role and avoiding the occurrence of shielding gaps, providing a reliable guarantee for the safe operation of the equipment and the safety of the operators;
[0025] In the second embodiment, the two designs of the shielding plate assembly each have their own advantages. The design using the linkage of the outer hinge and the inner hinge drives the guide rail to move up and down through the electric push rod, driving the shielding auxiliary plate to move. During operation, the telescopic sliding of the sliding rod and the movable sleeve drives the frame body to move, driving the shielding auxiliary plate to move left and right. This design does not require an additional fourth motor drive, has a lower cost, and is convenient for adjustment due to synchronous linkage. The design using the fourth motor drive enables the two shielding auxiliary plates to move independently, has the function of flexible adjustment, and has stronger adjustment adaptability. In short, the two designs respectively show unique advantages in cost control and adjustment flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

In this way, when the second motor 923 works, it can drive the first gear 924 to rotate, and then drive the arc-shaped rack 922 and the arc-shaped sliding plate 93 to slide inside the arc-shaped rail 91. This design enables the baffle device 6 to adjust its position in the arc direction according to needs, so as to better adapt to different radiotherapy scenarios, effectively block the rays, and protect the normal tissues of the patient.
[0066] As Figures 1 to 5 and Figure 9As shown in the figure, the displacement device 3 includes a suspension frame 31, which is fixedly connected to the outer end of the arc-shaped slide plate 93. The bottom of the suspension frame 31 is fixedly connected with a transverse rail 32. A sliding block 33 is slidably connected inside the transverse rail 32. The outside of the sliding block 33 is fixedly connected with a connecting arm 61. The top of the sliding block 33 is fixedly connected with a second driving assembly 34. The second driving assembly 34 includes a top frame 341 and a straight rack 342. The top frame 341 is fixedly connected to the top of the sliding block 33. The straight rack 342 is fixedly connected to the upper rear side of the transverse rail 32. The top of the top frame 341 is fixedly connected with a third motor 343. The output end of the third motor 343 penetrates through the top frame 341 and is fixedly connected with a second gear 344. The second gear 344 is meshed with the straight rack 342. The suspension frame 31 is fixed at the outer end of the arc-shaped slide plate 93, providing stable support for the transverse rail 32. The sliding block 33 is slidably connected inside the transverse rail 32, and the outside of the sliding block 33 is fixedly connected with the connecting arm 61, enabling the shielding plate device 6 to move on the transverse rail 32 through the sliding block 33. The top of the sliding block 33 is fixedly connected with a second driving assembly 34. The top frame 341 is fixed on the top of the sliding block 33, providing an installation position for the third motor 343. The straight rack 342 is fixed at the upper rear side of the transverse rail 32. The third motor 343 is fixed on the top of the top frame 341, and its output end penetrates through the top frame 341 and is fixedly connected with the second gear 344. The second gear 344 is meshed with the straight rack 342. When the third motor 343 works, it can drive the second gear 344 to rotate. Since the second gear 344 is meshed with the straight rack 342, the sliding block 33 is driven to slide inside the transverse rail 32. Such a design enables the shielding plate device 6 to adjust its position in the horizontal direction. Cooperating with the adjusting device 9, it can more flexibly adapt to different radiotherapy requirements, effectively block rays, and protect the normal tissues of patients.
[0067] As Figures 1 to 4 shown, both sides of the bottom of the bed body 5 are fixedly connected with support frames 7. The bottom of the support frames 7 is fixedly connected with support plates 8. Installation holes 11 are opened at both ends of the support plates 8. The installation holes 11 are countersunk holes. A pillow 10 is fixedly connected to one side of the top of the bed body 5. The support frames 7 on both sides of the bottom of the bed body 5 play an important supporting role. Installation holes 11 are opened at both ends of the support plates 8 at the bottom of the support frames 7, and the installation holes 11 are countersunk holes. The installation holes 11 can cooperate with bolts to assist in installing the device. Such a design makes the bed body 5 more stable during installation, capable of bearing the weight of the patient and various acting forces that may occur during the treatment process. At the same time, the pillow 10 fixedly connected to one side of the top of the bed body 5 provides comfortable support for the patient, enabling the patient to be more relaxed during radiotherapy, which helps to improve the treatment effect and the patient's cooperation. The settings of the support frames 7, support plates 8, and pillow 10 jointly ensure the stability of the bed body 5 and the comfort of the patient.
[0068] Embodiment 2:
[0069] like Figures 11 to 12 As shown, the auxiliary shielding assembly 124 includes a guide rail 1241 and an external hinge 1246, the guide rail 1241 is fixedly installed on the inner end of the bent connecting tube 123, the external hinge 1246 is hingedly installed on the middle part of the bottom two sides of the frame 62, the guide rail 1241 is internally slidably connected with a slider 1244, the inner side of the slider 1244 is fixedly installed with a shielding sub-plate 1245, the shielding sub-plate 1245 is arranged on the outer side of the shielding plate device 6, the top of the shielding sub-plate 1245 is hinged with an internal hinge 1247, the inner side of the external hinge 1246 is hingedly installed with a sliding rod 1248, the outer side of the inner hinge 1247 is hingedly installed with a movable sleeve 1249, and the inner end of the sliding rod 1248 is inserted into the interior of the movable sleeve 1249.
[0070] The shielding plate assembly is provided with an outer hinge 1246 and an inner hinge 1247. During its use, the electric push rod 122 can still be used to push the guide rail 1241 to move up and down, so that the shielding sub-plate 1245 can move up and down. In the adjustment process, the advantage is that there is no need to use an additional fourth motor 1242 for driving. The outer hinge 1246 and the inner hinge 1247 are linked to each other. During operation, when the frame 62 rotates and moves, the sliding rod 1248 can slide on the inner side of the movable sleeve 1249, thereby reserving space for the frame 62. When the frame 62 moves laterally, the sliding rod 1248 and the movable sleeve 1249 are linked to each other and limited. The two can only telescope and slide with each other, and the strength of the left and right activities cannot be adjusted. Therefore, the shielding sub-plate 1245 can be driven to move left and right. Obviously, by adopting the setting of the technical scheme of embodiment 2, there is no need for the additional drive of the fourth motor 1242, and the overall cost of use is relatively low. The design of driving by the fourth motor 1242 enables the two shielding sub-plates 1245 to move independently. It can be seen that the designs of the two shielding plate assemblies have certain advantages. The drive by the fourth motor 1242 can have the function of flexible adjustment, and the adaptability of adjustment is stronger. If the design of the linkage of the inner hinge 1247 and the outer hinge 1246 is adopted, there is no need to additionally set up the fourth motor 1242, and the overall cost of use is relatively low. At the same time, the synchronous linkage can also be convenient for adjustment. Due to the mutual sliding design of the sliding rod 1248 and the movable sleeve 1249, they can stably link with each other to cooperate with the linkage of the outer hinge 1246 and the inner hinge 1247, so that the electric push rod 122 can stably operate independently.
[0071] The workflow of the technical solution provided by the present invention is as follows:
[0072] By setting the displacement device 3 and the adjustment device 9 to cooperate, during the use of this device, if adjustment is required during the shielding process, the first driving component 92 can be activated according to specific requirements. At this time, the second motor 923 is started to operate. The second motor 923 can accurately drive the first gear 924 to rotate. Since the first gear 924 and the arc-shaped rack 922 are in meshing connection, as the second motor 923 drives the first gear 924 to rotate, the first gear 924 can drive the arc-shaped rack 922, thereby driving the arc-shaped slide plate 93 to slide along the arc-shaped rail 91. The arc-shaped slide plate 93 extends or contracts from the inside of the arc-shaped rail 91, which can cause the arc-shaped slide plate 93 to drive the shielding plate device 6 to displace along the arc. In this way, this device can extremely flexibly adapt to the radiotherapy of the patient's side during use. Moreover, during the treatment process, the third motor 343 can be started to operate. When the third motor 343 operates, it can drive the second gear 344 to rotate, and the second gear 344 is meshed with the straight rack 342. By starting the third motor 343 to drive the second gear 344 to rotate, the straight rack 342 can be used to apply a reverse extrusion force, and the resulting reaction force can drive the sliding block 33 to slide inside the cross rail 32. By adjusting the sliding of the sliding block 33 inside the inner side of the cross rail 32, the shielding plate device 6 can be flexibly adjusted to move above the patient on the bed body 5. It can be seen that the whole device can adjust the shielding plate device 6 in a circular displacement, and at the same time, it can also be adjusted linearly, maximizing the adaptation to the radiotherapy needs of the patient and significantly improving the adaptation performance of the whole device during use.
[0073] By setting the baffle device 6, during the use of this device, the first motor 634 can be started to operate. After the first motor 634 behind the side rail 631 operates, it can drive the lead screw 632 located inside the side side rail 631 to rotate. The thread directions at both ends of the lead screw 632 are opposite, and thus can synchronously drive the movable block 633 to displace and slide synchronously at both ends inside the side rail 631. This enables this device to flexibly adjust the sliding of the two side movable blocks 633. At this time, the movable block 633 can drive the upper connecting frame 643 to drive the transverse baffle 642 to perform a transverse displacement. During this period, the rotation of the lead screw 632 can drive the first bevel gear 6352 and the second bevel gear 6353 to drive each other. Since the first bevel gear 6352 and the second bevel gear 6353 are meshed with each other in transmission, when the lead screw 632 rotates, it can synchronously drive both the first bevel gear 6352 and the second bevel gear 6353 on the turntable 6351 to rotate, thereby being able to drive the lead screw 632 located inside the front side rail 631 to rotate. When the lead screw 632 of the front side rail 631 rotates, it can drive the movable block 633 inside the front side rail 631 to slide back and forth synchronously. At this time, the sliding of the front movable block 633 can drive the lower connecting frame 644 to drive the longitudinal baffle 641 to displace back and forth. It can be seen that by operating a single first motor 634, the transverse baffle 642 and the longitudinal baffle 641 can be synchronously driven to reciprocate and displace. By adjusting the transverse baffle 642 and the longitudinal baffle 641 to expand outward, the notch between the transverse baffle 642 and the longitudinal baffle 641 inside the frame 62 can be adjusted to expand. During the adjustment process, the lower connecting frame 644 is relatively long and narrow, and there is space reserved for the transverse baffle 642 inside the lower connecting frame 644 to prevent the lower connecting frame 644 from interfering with the movement of the transverse baffle 642 when it moves outward, enabling the transverse baffle 642 and the longitudinal baffle 641 to be stably and flexibly adjusted. It can be seen that by adjusting the transverse baffle 642 and the longitudinal baffle 641 to contract and merge, the notch between the transverse baffle 642 and the longitudinal baffle 641 can be reduced, enabling this device to quickly control the notch of the transverse baffle 642 and the longitudinal baffle 641 with only the operation of a single first motor 634. This enables the entire device not only to adjust the position of the baffle device 6, but also the entire baffle device 6 can be adjusted in size, and the whole can better adapt to the use of this device, greatly improving the adaptability performance during the use of this device.
[0074] By starting the operation of the electric push rod 122, after the electric push rod 122 starts, it can assist in pushing the bent connecting pipe 123 to move up and down. Further, this action will cause the shielding auxiliary plate 1245 to move up and down accordingly. The up and down movement of the shielding auxiliary plate 1245 can effectively assist in shielding the adjustment gap outside the shielding plate group, greatly improving the comprehensiveness of shielding. At the same time, start the operation of the fourth motor 1242. The first motor 634 drives the threaded rod 1243 to rotate, and then drives the slider 1244 to slide inside the guide rail 1241. By flexibly adjusting the sliding position of the slider 1244 inside the guide rail 1241, the adjustment of the lateral displacement of the shielding auxiliary plate 1245 inside the slider 1244 can be realized. In this way, the shielding auxiliary plate 1245 can closely follow the shielding plate group for displacement, and can be conveniently and comprehensively shielded in any state. Moreover, during the shielding process, using the electric push rod 122 to push the shielding auxiliary plate 1245 to move up and down can be adaptively adjusted according to different adjustment states of the shielding plate group, giving full play to the role of comprehensive protection, effectively avoiding the occurrence of shielding gaps, and providing a reliable guarantee for the safe operation of the equipment and the safety of the operators. The present invention covers any alternatives, modifications, equivalent methods, and solutions made on the essence and scope of the present invention.
