Description

Technical Field

[0001] The present invention relates to the technical field of radiology, and more particularly to a radiation shield for clinical use in radiology. Background Art

[0002] In the modern medical field, the radiology department plays a vital role. The radiology department mainly uses various radiation equipment to diagnose and treat patients. During the radiotherapy process, it is very important to accurately control the irradiation range of the radiation to ensure that while effectively treating the lesion, the damage to normal tissue is minimized.

[0003] At present, existing radiology departments usually use shielding plates to assist in protection during radiotherapy. Although such shielding plates can shield the radiation to a certain extent and prevent it from irradiating normal tissue, they have obvious limitations. First, the shielding plates are of a single size, and the radiation slots on the inside of the shielding plates used for treatment cannot be flexibly adjusted according to specific treatment needs. When the radiation range is small, the slots cannot be effectively reduced, which may cause too much normal tissue to be exposed to the radiation, increasing unnecessary radiation risks.

[0004] Secondly, the existing shielding plates cannot be adjusted to the side to shield the patient's side when the patient is undergoing radiotherapy. When radiotherapy is required on the patient's side, the existing shielding plates obviously cannot be flexibly adapted, which not only reduces the accuracy of radiotherapy, but may also 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 shortcomings of the existing shielding plates.

[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 scheme, the device cooperates with the displacement device and the adjustment device so that during use, the second motor can be started to drive the first gear to rotate. Since the first gear is meshed with the arc-shaped rack, the arc-shaped slide can be driven to slide along the arc-shaped rail, so that the shielding plate device can be displaced along the arc to adapt to the patient's sideways radiotherapy. At the same time, the third motor is started to drive the second gear to rotate. With the meshing connection with the spur rack, the reaction force drives the sliding block to slide in the horizontal rail, thereby flexibly adjusting the position of the shielding plate device above the patient on the bed. In this way, the device can adjust the shielding plate device in a circular displacement and can also perform linear displacement adjustment, which meets the different needs of patients for radiotherapy to the greatest extent and improves the overall adaptability of the equipment.

[0022] By setting up the shielding plate mechanism, during use, the first motor at the rear side of the side rail can be started to drive the internal screw rod of the side rail to rotate. Because the threads at both ends of the screw rod rotate in opposite directions, the movable block can be synchronously driven to slide on both ends of the side rail, thereby driving the upper connecting frame to drive the horizontal shielding plate to move horizontally. At the same time, the rotation of the screw rod drives the first bevel gear and the second bevel gear to transmit to each other, so that the internal screw rod of the front side rail rotates, drives the front movable block to slide, and drives the lower connecting frame to drive the longitudinal shielding plate to move forward and backward. In this way, the operation of the first motor can synchronously drive the horizontal shielding plate and the longitudinal shielding plate to reciprocate and move. This efficient synchronous drive design makes it more convenient to adjust the shielding plate and improves the operating efficiency.

[0023] By arranging the displacement device, the adjustment device and the shielding plate device in coordination, the device can not only adjust the position of the shielding plate device, but also adjust its size. By adjusting the horizontal shielding plate and the vertical shielding plate to expand outward, the slot between the two inside the frame can be enlarged; contraction and merging can reduce the slot. It can be seen that the device only needs one first motor to quickly operate the shielding plate slot. This design enables the device to better adapt to different radiotherapy scenes. Whether it is for treatment areas of different sizes or for body parts of patients in different positions, accurate shielding can be performed, which improves the practicality and adaptability of the device and brings more convenience and safety to patients' radiotherapy.

[0024] By starting the electric push rod, the bending connecting pipe can be pushed up and down, thereby driving the shielding sub-plate to move up and down, and assisting in shielding the adjustment gap on the outside of the shielding plate group to improve the comprehensiveness of shielding. At the same time, the fourth motor is started, and the first motor drives the threaded rod to rotate, so that the slider slides in the guide rail, thereby adjusting the lateral displacement of the shielding sub-plate on the inside of 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 pushes the shielding sub-plate to adapt and adjust according to the different adjustment states of the shielding plate group, play a comprehensive protective role, avoid the appearance of shielding gaps, and provide reliable protection for the safe operation of equipment and the safety of operators;

[0025] The two designs of the shielding plate assembly in Example 2 each have their own advantages. The design adopts a linkage between an external hinge and an internal hinge, and the guide rail is pushed up and down by an electric push rod to drive the shielding sub-plate to move. During operation, the sliding rod and the movable sleeve are telescopically slidable to coordinate the displacement of the frame, driving the shielding sub-plate to move left and right. This design does not require an additional fourth motor drive, has a low cost, and the synchronous linkage is easy to adjust. The design using the fourth motor drive allows the two shielding sub-plates to move independently, has a flexible adjustment function, and is more adaptable to adjustment. In short, the two designs each show unique advantages in cost control and adjustment flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] like Figures 1 to 5 and Fig. 9As shown, the displacement device 3 includes a hanging frame 31, which is fixedly connected to the outer end of the arc-shaped slide plate 93, and the bottom of the hanging frame 31 is fixedly connected to the cross rail 32, and the inside of the cross rail 32 is slidably connected to the sliding block 33, the outer side of the sliding block 33 is fixedly connected to the connecting arm 61, and the top of the sliding block 33 is fixedly connected to the second driving assembly 34, the second driving assembly 34 includes a top frame 341 and a spur rack 342, the top frame 341 is fixedly connected to the top of the sliding block 33, the spur rack 342 is fixedly connected to the rear upper end of the cross rail 32, the top of the top frame 341 is fixedly connected to the third motor 343, the output end of the third motor 343 passes through the top frame 341 and is fixedly connected to the second gear 344, the second gear 344 and the spur rack 342 are meshed and connected, the hanging frame 31 is fixed to the outer end of the arc-shaped slide plate 93, providing a stable support for the cross rail 32, the inside of the cross rail 32 is slidably connected to the sliding block 33, the outer side of the sliding block 33 is connected to the The connecting arm 61 is fixedly connected so that the baffle device 6 can move on the cross rail 32 through the sliding block 33. The top of the sliding block 33 is fixedly connected to the second driving assembly 34. The top frame 341 is fixed on the top of the sliding block 33 to provide an installation position for the third motor 343. The spur rack 342 is fixed on the upper end of the rear side of the cross rail 32. The third motor 343 is fixed on the top of the top frame 341. The output end of the third motor 343 passes through the top frame 341 and is fixedly connected to the second gear 344. The second gear 344 and the spur rack 342 are meshed and connected. When the third motor 343 is working, it can drive the second gear 344 to rotate. Since the second gear 344 is meshed with the spur rack 342, the sliding block 33 is driven to slide inside the cross rail 32. This design enables the baffle device 6 to adjust its position in the horizontal direction. In conjunction with the adjustment device 9, it can more flexibly adapt to different radiotherapy needs, effectively block radiation, and protect the patient's normal tissues.

[0067] like Figures 1 to 4 As shown, both sides of the bottom of the bed 5 are fixedly connected with supporting frames 7, and the bottom of the supporting frames 7 is fixedly connected with supporting plates 8. Both ends of the supporting plates 8 are provided with mounting holes 11, and the mounting holes 11 are set as countersunk holes. A pillow 10 is fixedly connected to one side of the top of the bed 5.

The mounting holes 11 can be used with bolts to assist in the installation of the device. This design makes the bed 5 more stable during installation and can withstand the weight of the patient and various forces that may be generated during the treatment process. At the same time, the pillow 10 fixedly connected to one side of the top of the bed 5 provides comfortable support for the patient, allowing the patient to relax more when receiving radiotherapy, which is helpful to improve the treatment effect and the patient's cooperation. The settings of the supporting frames 7, supporting plates 8 and pillows 10 jointly ensure the stability of the bed 5 and the comfort of the patient.

[0068] Embodiment 2:

[0069] like Figure 11 to Figure 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 arranging the displacement device 3 and the adjustment device 9 to cooperate, when the device is in use, if adjustment is required during the shielding process, the first drive assembly 92 can be started according to specific needs. At this time, the second motor 923 is started to run, and 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 a meshing connection state, as the second motor 923 drives the first gear 924 to rotate, the first gear 924 can drive the arc-shaped rack 922, and then drive 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 move along the arc. In this way, the device can be extremely flexibly adapted to the patient during use. The third motor 343 can be started to run, and the third motor 343 can drive the second gear 344 to rotate, and the second gear 344 is meshed with the spur rack 342. The third motor 343 is started to drive the second gear 344 to rotate, and the spur rack 342 can be reversely squeezed by the third motor 343. The reaction force generated can drive the sliding block 33 to slide inside the cross rail 32. The sliding block 33 is adjusted to slide on the inner side of the cross rail 32, and the baffle device 6 can be flexibly adjusted to move above the patient on the bed 5. It can be seen that the device as a whole can adjust the baffle device 6 in a ring-shaped displacement, and can also perform linear displacement adjustment to adapt to the patient's radiotherapy needs to the greatest extent, and significantly improve the adaptability of the device during overall use.

[0073] By setting up the shielding plate device 6, the device can be used to start the first motor 634. After the first motor 634 on the rear side of the side rail 631 is running, it can drive the screw rod 632 located inside the side rail 631 to rotate. The threads at both ends of the screw rod 632 rotate in opposite directions, and then the movable block 633 can be synchronously driven to move and slide synchronously at both ends of the side rail 631. This allows the device to flexibly adjust the sliding of the two movable blocks 633 located on the side. At this time, the movable block 633 can drive the upper connecting frame 643 to drive the horizontal shielding plate 642 to move horizontally. During this period, the screw rod The rotation of the screw rod 632 can drive the first bevel gear 6352 and the second bevel gear 6353 to transmit to each other. Since the first bevel gear 6352 and the second bevel gear 6353 are in transmission and meshing with each other, the rotation of the screw rod 632 can synchronously drive the first bevel gear 6352 and the second bevel gear 6353 on the turntable 6351 to rotate, thereby driving the screw rod 632 located inside the front side rail 631 to rotate. The rotation of the screw rod 632 of the front side rail 631 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 movable block 633 on the front side can drive the lower connecting frame 644 to drive the longitudinal The shielding plate 641 moves forward and backward. It can be seen that the device can synchronously drive the transverse shielding plate 642 and the longitudinal shielding plate 641 to move back and forth by operating a first motor 634. By adjusting the transverse shielding plate 642 and the longitudinal shielding plate 641 to expand outward, the slot between the transverse shielding plate 642 and the longitudinal shielding plate 641 inside the frame 62 can be adjusted to expand. During the adjustment process, the lower connecting frame 644 is overall narrow and long, and there is a space reserved for the transverse shielding plate 642 inside the lower connecting frame 644, so as to avoid the lower connecting frame 644 hindering the movement of the transverse shielding plate 642 when the transverse shielding plate 642 moves outward, so that the transverse shielding plate 642 can be prevented from moving outward. The plate 642 and the longitudinal shielding plate 641 can be adjusted stably and flexibly. It can be seen that the slot between the transverse shielding plate 642 and the longitudinal shielding plate 641 can be reduced by adjusting the transverse shielding plate 642 and the longitudinal shielding plate 641 to shrink and merge, so that the device only needs one first motor 634 to operate to quickly control the slots of the transverse shielding plate 642 and the longitudinal shielding plate 641, so that the device as a whole can not only adjust the shielding plate device 6 for position adjustment, but also the entire shielding plate device 6 can be adjusted in size, so that the whole can better adapt to the use of the device, which greatly improves the adaptability of the device during use.

[0074] By starting the electric push rod 122 to run, when the electric push rod 122 is started, it can assist in pushing the bent connecting pipe 123 up and down. Further, this action will prompt the shielding sub-plate 1245 to move up and down. The up and down movement of the shielding sub-plate 1245 can effectively assist in shielding the adjustment gap on the outside of the shielding plate group, greatly improving the comprehensiveness of the shielding. At the same time, the fourth motor 1242 is started to run, and the first motor 634 drives the threaded rod 1243 to rotate, thereby driving the slider 1244 to slide on the inner side of the guide rail 1241. By flexibly adjusting the slider 124 In the sliding position inside the guide rail 1241, the lateral displacement of the shielding sub-plate 1245 inside the slider 1244 can be adjusted. In this way, the shielding sub-plate 1245 can closely follow the displacement of the shielding plate group, and can conveniently perform comprehensive shielding in any state. In addition, during the shielding process, the electric push rod 122 is used to push the shielding sub-plate 1245 up and down, and it can be adapted and adjusted according to the 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 reliable protection for the safe operation of the equipment and the safety of operators. The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to enable the public to have a thorough understanding of the present invention, the specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0075] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
