Description

Technical Field

[0001] This invention relates to the field of radiation protection device technology, specifically a radiation protection device that moves with the X-ray tube under C-arm fluoroscopy. Background Technology

[0002] A C-arm X-ray machine is a device used for medical imaging examinations, typically in operating rooms and emergency rooms. It generates X-rays and uses computer technology to process images, helping doctors to observe the patient's internal condition in real time during surgery or other treatments. It mainly consists of a C-shaped frame, an X-ray tube that generates X-rays, an image intensifier and CCD camera that acquire images, and an image processing workstation.

[0003] However, existing C-arm X-ray machines have the following problems when in use: In C-arm X-ray fluoroscopy, the X-ray tube and detector rotate around the patient to obtain images from different angles. During fluoroscopy, soft rays are dispersed to the surroundings. If there are people around, they may radiate into the bodies of healthy people. However, existing radiation protection devices (such as lead screens and lead aprons) are usually static and cannot move with the X-ray tube, resulting in a high risk of radiation exposure for medical staff. To address this, we have introduced a radiation protection device that moves with the X-ray tube during C-arm fluoroscopy. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-13 The present invention provides a technical solution:

[0034] Example 1:

[0035] A radiation protection device that moves with the X-ray tube during C-arm fluoroscopy includes an assembly ring 1. Two adjusting screws 36 are screwed onto the outer circumference of the assembly ring 1. The assembly ring 1 is fitted onto the outer side of the X-ray tube inside the C-arm 40. After fitting, the assembly ring 1 is connected to the X-ray tube by tightening the adjusting screws 36. Connecting blocks 4 are movably connected to the lower circumference of the assembly ring 1. Several connecting plates 8 are provided on the lower side of the connecting blocks 4, and these connecting plates 8 are movably connected to each other. Two third mounting holes 26 are opened in the lower end of the connecting blocks 4. Two second mounting rings 33 are fixedly connected to the upper end of the connecting plates 8, and the second mounting rings 33 are installed in the third mounting holes 26 by screws. Inside 6, the two second mounting rings 33 connected to the upper end of the connecting plate 8 are inserted into the third mounting hole 26, and the second mounting rings 33 are fixed in the third mounting hole 26 by external screws. At this time, the connecting plate 8 is connected to the connecting block 4. The connecting plate 8 is provided with a first storage cavity 35. A radiation protection cloth 27 is fixedly connected in the first storage cavity 35. The radiation protection cloth 27 is a flexible protective cloth made of lead composite material. The radiation protection cloth 27 is folded and placed in the second storage cavity 29. The lower end of the radiation protection cloth 27 extends into the external environment and is fixedly connected to the connecting rod 13. Two first screw holes 19 are opened on the outer side of the connecting rod 13.

[0036] The connecting plate 8 is provided with a first unfolding mechanism. One end of the first unfolding mechanism is fixedly connected to the connecting rod 13, and the other end is connected to the connecting cavity 20. The connecting cavity 20 is opened in the connecting plate 8. Gas enters into the connecting cavity 20 and then enters the first unfolding mechanism, which drives the first unfolding mechanism to extend outward. The outwardly extending first unfolding mechanism drives the folded radiation protection cloth 27 to extend outward. A blocking mechanism is movably connected in the connecting cavity 20. A connecting inflation mechanism is provided in the lower end of the connecting block 4. When the lower end of the connecting block 4 is connected to the upper end of the connecting plate 8, the lower end of the inflation mechanism will be inserted into the connecting cavity 20, so that the blocking mechanism can remove its obstruction of the connecting cavity 20, and the gas generated by the inflation mechanism can enter the connecting cavity 20.

[0037] The first storage cavity 35 is equipped with a tensioning mechanism. One end of the tensioning mechanism is connected to the connecting cavity 20. When the radiation protection cloth 27 is unfolded, the tensioning mechanism will move a certain distance. After the radiation protection cloth 27 is unfolded, the tensioning mechanism will tighten and straighten the unfolded radiation protection cloth 27 by moving. The lower side of the assembly ring 1 is equipped with L-shaped connecting plates 9. Both ends of the L-shaped connecting plates 9 are movably connected to the corresponding connecting plates 8. The L-shaped connecting plates 9 are equipped with a second storage cavity 29. The L-shaped radiation protection cloth 5 is fixedly connected in the second storage cavity 29. The lower end of the L-shaped radiation protection cloth 5 is fixedly connected to the L-shaped connecting rod 28. The L-shaped connecting rod 28 is also equipped with two first screw holes 19 on the outside. Through the setting of the first screw holes 19, the L-shaped connecting rod 28 can be connected to the connecting rod 13. The L-shaped connecting plate 9 is equipped with a second unfolding mechanism. One end of the second unfolding mechanism is fixedly connected to the L-shaped connecting rod 28.

[0038] Example 2:

[0039] Based on Example 1, in order to adjust the size of the square protective structure composed of several radiation shielding cloths 27 and several L-shaped radiation shielding cloths 5, a connecting block 4 is movably connected to the lower end of the assembly ring 1, and a sliding block 2 is fixedly connected to the upper end of the connecting block 4. The sliding block 2 is slidably connected to the lower end of the assembly ring 1, and a screw rod 3 is screwed into the sliding block 2. The screw rod 3 is movably connected to the assembly ring 1, and one end of the screw rod 3 extends into the external environment. By rotating the screw rod 3, the sliding block 2 can be moved along the lower end of the assembly ring 1. The movement of the sliding block 2 will drive the connecting block 4 to move synchronously. By adjusting the position of the sliding block 2 in four directions, the size of the square protective structure can be controlled. After the adjustment is completed, the corresponding connecting plate 8 can be installed or removed. At the same time, through the detachable L-shaped connecting plate 9 and the connecting plate 8, when the radiation shielding cloth 27 and the L-shaped radiation shielding cloth 5 are damaged, the corresponding L-shaped connecting plate 9 and the connecting plate 8 can be removed and replaced.

[0040] The first deployment mechanism includes two first telescopic air tubes 37. The lower end of the first telescopic air tube 37 is fixedly connected to the connecting rod 13, and the upper end is fixedly connected to the connecting plate 8 and communicates with the first air guide cavity 12. The first air guide cavity 12 is opened in the connecting plate 8. The end of the first air guide cavity 12 away from the first telescopic air tube 37 is connected to the connecting cavity 20. The gas entering the first air guide cavity 12 will enter the two first telescopic air tubes 37. At this time, the first telescopic air tubes 37 will extend outward under the push of the gas. The two first telescopic air tubes 37 extending outward will drive the connecting rod 13 to move. The movement of the connecting rod 13 will drive the radiation protection cloth 27 to move outward and unfold.

[0041] The blocking mechanism includes a T-shaped block 21, with slide rods 22 fixedly connected to both ends of the T-shaped block 21. The slide rods 22 slide in the communicating cavity 20, and a support spring 23 is fixedly connected in the communicating cavity 20. The upper end of the support spring 23 is fixedly connected to the slide rod 22.

[0042] The inflation mechanism includes a bidirectional micro air pump 24. The size and model of the micro air pump 24 can be selected according to the actual use. The bidirectional micro air pump 24 is fixedly installed in the connecting block 4. One end of the bidirectional micro air pump 24 is fixedly connected to the first solenoid valve 25, and the other end is connected to the external environment. The lower end of the first solenoid valve 25 is fixedly connected to the insertion tube 34. The lower end of the insertion tube 34 is inserted into the connecting cavity 20. The outer side of the insertion tube 34 is provided with several through holes and a rubber layer is provided on the outer side of the insertion tube 34. The rubber layer ensures the sealing between the insertion tube 34 and the connecting cavity 20.

[0043] The tensioning mechanism includes a tensioning rod 6, with both ends of the tensioning rod 6 arranged in a T-shape and slidingly connected to a T-slot 14. The T-slot 14 is formed within the connecting plate 8, and a return spring 15 is fixedly connected within the T-slot 14. The other end of the return spring 15 is fixedly connected to the tensioning rod 6. During installation, the insertion pipe 34 is inserted into the connecting cavity 20. At this time, the T-shaped block 21 located in the connecting cavity 20 will be pushed to move, and the support spring 23 will be compressed. The T-slot 14 is fixedly connected to the return spring 25. The second telescopic air pipe 17 has its other end fixedly connected to the tensioning rod 6. One end of the second telescopic air pipe 17 is fixedly connected to the air guide pipe 18, which is fixedly connected inside the connecting plate 8. The end of the air guide pipe 18 away from the second telescopic air pipe 17 is fixedly connected to the output end of the third solenoid valve 38, which is fixedly connected to the outside of the connecting plate 8. The input end of the third solenoid valve 38 is connected to the connecting cavity 20, and a second solenoid valve 39 is fixedly installed on the outside of the air guide pipe 18.

[0044] Two connecting cavities 10 are formed inside the connecting plate 8. The opposite ends of the two connecting cavities 10 are connected to the connecting cavity 20. The end of the connecting cavity 10 away from the connecting cavity 20 is connected to the external environment. A first mounting hole 11 is formed in one end of the connecting plate 8. A connecting pipe 16 and a first mounting ring 7 are fixedly connected to the other end of the connecting plate 8. The first mounting ring 7 is inserted into the first mounting hole 11 and fixed by a screw to realize the mutual installation of the two connecting plates 8. The connecting cavities 10 in the two connecting plates 8 are connected to each other through the connecting pipe 16 inserted into the connecting cavity 10.

[0045] The second deployment mechanism includes a third telescopic air tube 30. One end of the third telescopic air tube 30 is fixedly connected to an L-shaped connecting rod 28, and the other end is fixedly connected to an L-shaped connecting plate 9. The upper end of the third telescopic air tube 30 is connected to a T-shaped connecting cavity 31, which is located inside the L-shaped connecting plate 9. Both ends of the T-shaped connecting cavity 31 are connected to the external environment. A second mounting hole 32 is provided in one end of the L-shaped connecting plate 9, and a connecting pipe 16 and a first mounting ring 7 are also fixedly connected to the other end of the L-shaped connecting plate 9. The gas entering the T-shaped connecting cavity 31 will enter the third telescopic air tube 30. The movement of the third telescopic air tube 30 will drive the L-shaped connecting rod 28 to move, and the movement of the L-shaped connecting rod 28 will drive the L-shaped radiation protection cloth 5 to move and deploy.

[0046] Working principle: When in use, the assembly ring 1 is sleeved onto the outside of the ball tube inside the C-arm 40. After sleeved, the assembly ring 1 is connected to the ball tube by tightening the adjusting screw 36. Several connecting plates 8 are connected together as needed, and one of the connecting plates 8 is connected to the connecting block 4. Specifically, the first mounting ring 7 set at one end of one connecting plate 8 is inserted into the first mounting hole 11 in the other connecting plate 8. The first mounting ring 7 is fixed in the first mounting hole 11 by the external screw. At the same time, the connecting tube 16 is inserted into the connecting cavity 10. At this time, the connecting cavities 10 in the two connecting plates 8 will be interconnected.

[0047] Simultaneously, during the installation of the two connecting plates 8 together, ensure that the radiation protection cloth 27 inside the two connecting plates 8 can be stacked and in contact. At the same time, stack the two connecting rods 13 together and connect the two connecting rods 13 by passing the external bolts through the first screw hole 19. Connect the two ends of the L-shaped connecting plate 9 to the corresponding connecting plates 8 respectively. Specifically, insert the first mounting ring 7 connected to one end of the connecting plate 8 near the L-shaped connecting plate 9 into the second mounting hole 32. After insertion, fix it with screws. Insert the first mounting ring 7 connected to one end of the L-shaped connecting plate 9 into the first mounting hole 11 located in the connecting plate 8 and connect it with screws to realize the mutual connection between the L-shaped connecting plate 9 and the connecting plate 8. After several connecting plates 8 and several L-shaped connecting plates 9 are connected, a square structure is formed.

[0048] The connecting blocks 4 arranged around the lower side of the assembly ring 1 are connected to the connecting plate 8. Specifically, the two second mounting rings 33 connected to the upper end of the connecting plate 8 are inserted into the third mounting hole 26, and the second mounting rings 33 are fixed in the third mounting hole 26 by external screws. At this time, the connecting plate 8 and the connecting block 4 are connected together. At the same time, during the installation process, the insertion pipe 34 will be inserted into the connecting cavity 20. At this time, the T-shaped block 21 located in the connecting cavity 20 will be pushed to move, and the support spring 23 will be compressed.

[0049] After connecting the wiring harnesses of components such as the bidirectional micro air pump 24, the first solenoid valve 25, and the second solenoid valve 39 to the hub, and then connecting the hub to the equipment interface inside the C-arm 40, the start and stop of the corresponding components can be completed through program settings.

[0050] By rotating the C-arm 40, the X-ray tube is moved to the position to be irradiated. During the rotation of the C-arm 40, the adapter ring 1 moves with the C-arm 40. When the X-ray tube is irradiated, the equipment interface inside the C-arm 40 transmits a signal, and the program controls the bidirectional micro air pump 24 to start and introduce external gas into the first solenoid valve 25. At this time, the first solenoid valve 25 is in the open state, and the gas enters the connecting cavity 20 through the insertion tube 34. The gas entering the connecting cavity 20 will enter the connecting cavity 10 of other connecting plates 8 in sequence through the connecting cavity 10. The gas entering the connecting cavity 20 will enter the first gas guide cavity 12 and the third solenoid valve 38. The gas entering the first gas guide cavity 12 will enter the two first telescopic air tubes 37. At this time, the first telescopic air tubes 37 will extend outward under the push of the gas. The two first telescopic air tubes 37 extend outward and drive the connecting rod 13 to move. The movement of the connecting rod 13 drives the radiation protection cloth 27 to move outward and unfold.

[0051] The gas entering the T-shaped connecting cavity 31 will enter the third telescopic air pipe 30. The movement of the third telescopic air pipe 30 will drive the L-shaped connecting rod 28 to move, and the movement of the L-shaped connecting rod 28 will drive the L-shaped radiation protection cloth 5 to move and unfold.

[0052] The gas entering the third solenoid valve 38 enters the air guide tube 18, and the gas entering the air guide tube 18 enters the second telescopic air tube 17. The second telescopic air tube 17 is supported by the gas, which pushes the tensioning rod 6 to move along the T-slot 14, so that the return spring 15 is compressed. When the L-shaped radiation protection cloth 5 and the radiation protection cloth 27 are unfolded to the designated position, the first solenoid valve 25 is closed to prevent gas leakage. The L-shaped radiation protection cloth 5 and the radiation protection cloth 27 will always be in the unfolded state. The third solenoid valve 38 is closed and the second solenoid valve 39 is opened. At this time, the gas in the second telescopic air tube 17 will be discharged into the external environment through the second solenoid valve 39. Under the elastic force of the return spring 15, the tensioning rod 6 will move upward. Since a rubber strip is fixedly connected to one end of the tensioning rod 6, the radiation protection cloth 27 will be pulled upward and tightened under the action of the rubber strip.

[0053] During X-ray irradiation, the square protective structure composed of several radiation shielding cloths 27 and several L-shaped radiation shielding cloths 5 blocks the discrete soft rays. When the X-ray tube is turned off and the X-ray is emitted, the equipment interface located in the C-arm 40 sends a signal to the beam, causing the first solenoid valve 25 to open. At the same time, the bidirectional micro air pump 24 draws air outward. During the air drawing process, the first telescopic air tube 37 and the third telescopic air tube 30 retract together, causing the radiation shielding cloths 27 and L-shaped radiation shielding cloths 5 to be folded and stored together again.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
