Description

Technical Field

[0001] The present invention relates to the technical field of tumor radiotherapy auxiliary equipment, and particularly to a positioning device for a lead protector for tumor radiotherapy. Background Art

[0002] During the process of tumor radiotherapy, lead protectors play a crucial role. Due to the high density of lead, it has excellent radiation blocking ability, which can effectively reduce the penetration of rays, thereby providing good protection for the patient's normal tissues. However, in order to enable the lead protector to accurately play its protective role, it is crucial to drill holes in it precisely.

[0003] Currently, in the installation and hole - drilling links of lead protectors, some intractable problems are faced. When common clamping structures come into contact with lead protectors, they are mostly in direct hard contact. When hole - drilling operations are carried out, the strong vibrations generated by the hole - drilling equipment will be quickly transmitted to the lead protector. Due to the lack of effective buffering and fixing mechanisms, the lead protector itself is extremely prone to dislocation under the influence of vibrations. Once this dislocation phenomenon occurs, it will directly lead to deviation of the hole - drilling position, seriously affecting the accuracy of hole - drilling.

[0004] The decrease in hole - drilling accuracy may not only weaken the protective performance of the lead protector and fail to achieve the expected protective effect, but also may require re - drilling or manufacturing of the lead protector, increasing the input of time and cost. For the medical field of tumor radiotherapy, which has extremely high requirements for accuracy, such defects are undoubtedly key problems that need to be solved urgently. Summary of the Invention

[0005] In order to overcome the existing problems, the embodiment of the present application provides a positioning device for a lead protector for tumor radiotherapy, which is provided with a base. Above the base, there is a vertical plate. On one side of the vertical plate, there is a cross - brace. On the upper surface of the cross - brace, there is a lifting component. At the position corresponding to the lifting component on the lower surface, there is a clamping component. On the side far from the clamping component, there is a fastening component. Above the fastening component, the cross - brace is provided with a connecting pipe, which corresponds to the drill rod of an external drilling device. During the hole - drilling operation, the position to be drilled on the lead protector coincides with the connecting pipe. The lifting component operates to drive the clamping component to fix the lead protector. The clamping component is fixed in the way of a suction cup structure, effectively eliminating the displacement of the lead protector caused by vibrations during the hole - drilling process, ensuring that the hole - drilling position is accurate and providing a highly reliable protection guarantee for tumor radiotherapy.

[0006] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0007] A positioning device for a lead protector for tumor radiotherapy, including a base. The base is made of a firm and stable material, such as stainless steel. Above the base, there is a vertical plate. On one side of the vertical plate, there is a cross - brace. The vertical plate and the cross - brace are made of high - strength metal materials to ensure the stability of the structure. On one side of the cross - brace, there is a clamping mechanism;

[0008] Among them, the clamping mechanism includes a lifting component located on the upper surface of the cross brace. At the corresponding position of the lifting component on the lower surface of the cross brace, a clamping component is provided. On the upper surface of one end of the cross brace, a connecting pipe is provided. The connecting pipe is made of wear-resistant and accurately positioned material. Place the lead protector to be opened on the lower surface of the cross brace, and the position to be drilled corresponds to the connecting pipe. Under the operation of the lifting component, the clamping component clamps the lead protector. Place the lead protector on the lower surface of the cross brace through the opening at the bottom end of the vertical plate, and align the position of the lead protector to be drilled with the connecting pipe above the cross brace, so that the position to be drilled is aligned with the connecting pipe. Place the lead protector in a suitable position so that the position to be drilled is aligned with the connecting pipe. Start the lifting component, and the lifting component drives the clamping component to move downwards to clamp the lead protector tightly. Adjust the height of the fastening component for limiting, and then perform the drilling operation.

[0009] Preferably, a fastening component is provided on the lower surface of the cross brace corresponding to the connecting pipe. The fastening component and the cross brace are of detachable structure. Due to the dual fixing effects of the clamping component and the fastening component, the vibration generated during drilling is effectively buffered and absorbed, preventing the lead protector from shifting or misaligning due to vibration, thus ensuring the stability and accuracy of the drilling operation.

[0010] Preferably, the fastening component includes a sleeve connected to the cross brace. A screw rod is screwed at the bottom end of the sleeve. The screw rod is in threaded connection with the sleeve. The screw rod is fixedly connected to the rotating shaft. A rotating shaft is provided below the screw rod. A bottom plate is provided at the bottom end of the rotating shaft. A rotating shaft is provided at the corresponding position of the bottom plate. And due to the setting of the rotating shaft, when the bottom plate contacts the lead protector, when the rotating shaft rotates, the large friction between the bottom plate and the lead protector is avoided through the rotating shaft. The rotating shaft inside the fastening component drives the screw rod to move up and down through the rotation of the rotating shaft, freely adjusting the height of the fastening component to further limit and fix the lead protector from above.

[0011] Preferably, the lifting component includes a connecting seat connected to the vertical plate. A cylinder body is provided on one side of the connecting seat. A transmission shaft is provided inside the cylinder body. When the cylinder body inside the lifting component operates, it drives the transmission shaft to operate, driving the clamping component to move downward. The suction cup body at the bottom end of the clamping component contacts the lead protector and applies pressure to firmly fix the lead protector.

[0012] Preferably, the clamping component includes a frame. A connecting column connected to the lifting component is provided above the frame. A suction cup body is provided on the lower surface of the frame. There are two suction cup bodies in total. The two suction cup bodies are fixedly connected to the frame. When the suction cup body contacts the lead protector, due to the material of the suction cup body itself, hard contact with the lead protector can be avoided.

[0013] Preferably, grooves are provided at corresponding positions of the vertical plate and the base. The width of the cross brace is smaller than the width of the vertical plate and larger than the width of the groove.

[0014] The advantages of the embodiments of the present application are as follows:

[0015] 1. There is a base, a vertical plate is provided above the base, a cross brace is provided on one side of the vertical plate, a lifting assembly is provided on the upper surface of the cross brace, a clamping assembly is provided at a position corresponding to the lifting assembly on the lower surface, and a fastening assembly is provided on the side away from the clamping assembly. A connecting pipe is provided above the fastening assembly on the cross brace, and the connecting pipe corresponds to the drill rod of an external drilling device. During the drilling operation, the position to be drilled of the lead protector coincides with the connecting pipe. The lifting assembly operates to drive the clamping assembly to fix the lead protector. The clamping assembly is fixed by using a suction cup structure, effectively eliminating the displacement of the lead protector caused by vibration during the drilling process, ensuring that the drilling position is accurate and providing a highly reliable protection guarantee for tumor radiotherapy.

[0016] 2. The fastening assembly includes a rotating shaft, and a lead screw is provided at the bottom end of the rotating shaft. Rotating the rotating shaft drives the lead screw to move up and down, which can change the height of the fastening assembly itself to limit the lead protector.

Through the design of the fastening assembly and the clamping assembly, the drilling process is more stable, avoiding the deviation of the lead protector due to vibration and improving the accuracy of drilling.

[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the general idea is as follows:

[0028] Embodiment 1

[0029] This embodiment gives the specific structure of a positioning device for a lead protector in tumor radiotherapy, as Figures 1-5 shown, including a base 1. The base 1 is made of a strong and stable material, such as stainless steel. A vertical plate 2 is arranged above the base 1. A cross brace 3 is arranged on one side of the vertical plate 2. The vertical plate 2 and the cross brace 3 are made of high-strength metal materials to ensure the stability of the structure. A clamping mechanism is arranged on one side of the cross brace 3;

[0030] Among them, the clamping mechanism includes a lifting component 4 located on the upper surface of the cross brace 3, and a clamping component 5 is provided at the corresponding position on the lower surface of the cross brace 3 where the lifting component 4 is located. A connecting pipe 7 is provided on the upper surface of one end of the cross brace 3. The connecting pipe 7 is made of wear-resistant and accurately positioned material. Place the lead protector to be opened on the lower surface of the cross brace 3, and the position to be punched corresponds to the connecting pipe 7. The clamping component 5 clamps the lead protector under the operation of the lifting component 4. Place the lead protector on the lower surface of the cross brace 3 through the opening at the bottom end of the vertical plate 2, and make the position of the lead protector to be punched correspond to the connecting pipe 7 above the cross brace 3, so that the position to be punched is aligned with the connecting pipe 7. Place the lead protector in a suitable position so that the position to be punched is aligned with the connecting pipe 7. Start the lifting component 4, and the lifting component 4 drives the clamping component 5 to move downward to clamp the lead protector tightly. Adjust the height of the fastening component 6 for limiting, and then perform the punching operation.

[0031] A fastening component 6 is provided on the lower surface of the cross brace 3 corresponding to the connecting pipe 7. The fastening component 6 and the cross brace 3 are of detachable structure. Due to the dual fixing effects of the clamping component 5 and the fastening component 6, the vibration generated during punching is effectively buffered and absorbed, preventing the lead protector from shifting or misaligning due to vibration, thus ensuring the stability and accuracy of the punching operation.

[0032] The fastening component 6 includes a sleeve 61 connected to the cross brace 3. A lead screw 62 is screwed at the bottom end of the sleeve 61. The lead screw 62 is threadedly connected to the sleeve 61. The lead screw 62 is fixedly connected to a rotating shaft 63. A rotating shaft 63 is provided below the lead screw 62. A bottom plate 64 is provided at the bottom end of the rotating shaft 63. A rotating shaft 65 is provided at the corresponding position of the bottom plate 64 and the rotating shaft 65. And due to the setting of the rotating shaft 65, when the bottom plate 64 contacts the lead protector, when the rotating shaft 63 rotates, the rotating shaft 65 avoids generating a large frictional force between the bottom plate 65 and the lead protector. The rotating shaft 63 inside the fastening component 6 drives the lead screw 62 to move up and down through the rotation of the rotating shaft 63, freely adjusting the height of the fastening component 6 to further limit and fix the lead protector from above.

[0033] The lifting component 4 includes a connecting seat 43 connected to the vertical plate 2. A cylinder body 41 is provided on one side of the connecting seat 43. A transmission shaft 42 is provided inside the cylinder body 41. When the cylinder body 41 inside the lifting component 4 operates, it drives the transmission shaft 42 to operate, driving the clamping component 5 to move downward. The suction cup body 53 at the bottom end of the clamping component 5 contacts the lead protector and applies pressure to firmly fix the lead protector.

[0034] The clamping assembly 5 includes a frame 52. Above the frame 52, there is a connecting column 51 connected to the lifting assembly 4. On the lower surface of the frame 52, there are suction cup bodies 53. There are two suction cup bodies 53 in total, and the two suction cup bodies 53 are fixedly connected to the frame 52. When the suction cup bodies 53 contact the lead protector, due to the material of the suction cup bodies 53 themselves, hard contact with the lead protector can be avoided.

[0035] At the corresponding positions of the vertical plate 2 and the base 1, there are grooves. The width of the cross brace 3 is less than the width of the vertical plate 2, and the width of the cross brace 3 is greater than the width of the groove.

[0036] By adopting the above technical solutions:

[0037] In the radiotherapy department of a large tumor hospital, a technician is using the lead protector positioning device of the present invention to make a lead protector for a patient.

[0038] First, place the lead protector on the lower surface of the cross brace 3 through the opening at the bottom end of the vertical plate 2, and align the position of the lead protector to be drilled with the connecting pipe 7 above the cross brace 3. Start the lifting assembly 4. The transmission shaft 42 inside the lifting assembly 4 runs, driving the clamping assembly 5 to move downward. The suction cup bodies 53 at the bottom end of the clamping assembly 5 contact the lead protector and apply pressure, firmly fixing the lead protector. The clamping assembly 5 firmly clamps the lead protector, the drilling process is smooth, the positions of the drilled holes are accurate, meeting the strict requirements of radiotherapy protection, and providing more effective protection for the patient.

A connecting pipe 7 is provided on the upper surface of one end of the cross brace 3. The connecting pipe 7 is made of wear-resistant and accurately positioned material. Place the lead protector to be opened on the lower surface of the cross brace 3. The position to be punched corresponds to the connecting pipe 7. The clamping component 5 clamps the lead protector under the operation of the lifting component 4. Place the lead protector on the lower surface of the cross brace 3 through the opening at the bottom end of the vertical plate 2, and align the position of the lead protector to be punched with the connecting pipe 7 above the cross brace 3, so that the position to be punched is aligned with the connecting pipe 7. Place the lead protector in a suitable position so that the position to be punched is aligned with the connecting pipe 7. Start the lifting component 4. The lifting component 4 drives the clamping component 5 to move downward to clamp the lead protector tightly, adjust the height of the fastening component 6 for limiting, and then perform the punching operation.

[0042] A fastening component 6 is provided on the lower surface of the cross brace 3 corresponding to the connecting pipe 7. The fastening component 6 and the cross brace 3 are of detachable structure. Due to the dual fixing effects of the clamping component 5 and the fastening component 6, the vibration generated during punching is effectively buffered and absorbed, preventing the lead protector from shifting or misaligning due to vibration, thus ensuring the stability and accuracy of the punching operation.

[0043] The fastening component 6 includes a sleeve 61 connected to the cross brace 3. A screw rod 62 is screwed at the bottom end of the sleeve 61. The screw rod 62 is in threaded connection with the sleeve 61. The screw rod 62 is fixedly connected to a rotating shaft 63. A rotating shaft 63 is provided below the screw rod 62. A bottom plate 64 is provided at the bottom end of the rotating shaft 63. A rotating shaft 65 is provided at the corresponding position of the bottom plate 64. And due to the setting of the rotating shaft 65, when the bottom plate 64 contacts the lead protector, when the rotating shaft 63 rotates, the large friction between the bottom plate 65 and the lead protector is avoided through the rotating shaft 65. The rotating shaft 63 inside the fastening component 6 drives the screw rod 62 to move up and down through the rotation of the rotating shaft 63, freely adjusting the height of the fastening component 6 to further limit and fix the lead protector from above.

[0044] The lifting component 4 includes a connecting seat 43 connected to the vertical plate 2. A cylinder body 41 is provided on one side of the connecting seat 43. A transmission shaft 42 is provided inside the cylinder body 41.

[0045] The clamping component 5 includes a frame 52. A connecting column 51 connected to the lifting component 4 is provided above the frame 52. A suction cup body 53 is provided on the lower surface of the frame 52. There are two suction cup bodies 53 in total. The two suction cup bodies 53 are fixedly connected to the frame 52. When the suction cup body 53 contacts the lead protector, due to the material of the suction cup body 53 itself, hard contact with the lead protector can be avoided.

[0046] A groove is provided at the corresponding position of the vertical plate 2 and the base 1 , the width of the horizontal support 3 is smaller than the width of the vertical plate 2 , and the width of the horizontal support 3 is larger than the width of the groove.

[0047] By adopting the above technical solution:

[0048] In a professional radiotherapy equipment manufacturing factory, workers use this positioning device to mass-produce lead guards.

[0049] The lead guard is placed on the lower surface of the cross brace 3 through the opening at the bottom end of the vertical plate 2, and the position of the lead guard to be punched is aligned with the connecting pipe 7 above the cross brace 3, and the lifting component 4 is started. The transmission shaft 42 inside the lifting component 4 runs, driving the clamping component 5 to move downward, and the suction cup body 53 at the bottom end of the clamping component 5 contacts and applies pressure to tightly fix the lead guard. The clamping component 5 firmly clamps the lead guard, and the rotating shaft 63 inside the fastening component 6 is adjusted. The rotation of the rotating shaft 63 drives the screw rod 62 to move up and down, and the height of the fastening component 6 is freely adjusted. The lead guard is further limited and fixed from above. The lifting component 4, the clamping component 5 and the fastening component 6 work together tacitly, and both small and large lead guards can be accurately positioned and punched, which greatly improves production efficiency and product quality.

[0050] Here’s how it works:

[0051] First, place the lead guard on the lower surface of the cross brace 3 through the opening at the bottom end of the vertical plate 2, and align the position of the lead guard to be punched with the connecting pipe 7 above the cross brace 3 so that the position to be punched is aligned with the connecting pipe 7.

[0052] Then, the lifting assembly 4 is started, and the transmission shaft 42 inside the lifting assembly 4 runs, driving the clamping assembly 5 to move downward, and the suction cup body 53 at the bottom end of the clamping assembly 5 contacts the lead guard and applies pressure to tightly fix the lead guard.

[0053] Afterwards, according to actual needs, the rotating shaft 63 inside the fastening assembly 6 is adjusted, and the screw rod 62 is driven to move up and down by the rotation of the rotating shaft 63, so that the height of the fastening assembly 6 can be freely adjusted, and the lead guard can be further limited and fixed from above.

[0054] During the drilling process, due to the dual fixing effect of the clamping component 5 and the fastening component 6, the vibration generated by the drilling is effectively buffered and absorbed, preventing the lead guard from being displaced or misplaced due to the vibration. In this way, the stability and accuracy of the drilling operation can be ensured, and the drilling position is accurate, meeting the strict requirements of tumor radiotherapy for lead guards.

[0055] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present invention, rather than limitations on the implementation manners. For those of ordinary skill 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 enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
