Description

Technical Field

[0001] This invention relates to the field of medical radiation protection and auxiliary technology, which is mainly applied in interventional radiology procedures, including cardiovascular intervention, neurointervention, and interventional tumor treatment. Technical Background In radiological diagnosis and treatment, ionizing radiation such as X-rays and gamma rays are generated by the interaction of radioactive nuclides or high-energy particles, forming beams of particles or photons with specific energies. These types of radiation are indispensable in image-guided surgeries (such as cardiovascular interventions and tumor embolization), but they also pose significant occupational health risks to healthcare workers exposed to them over long periods. Traditional protective measures mainly rely on two types of equipment: wearable protective gear (such as lead aprons and lead vests) and fixed shielding devices. However, existing technologies have the following limitations: (1) Defects of wearable protective equipment Local exposure risk: To ensure the flexibility of surgical procedures, lead aprons are usually not designed to cover the arms, ears, nose and face, which leads to long-term exposure of these areas to scattered radiation, which can easily cause occupational diseases such as skin keratinization, nail root congestion, hearing loss and cataracts.

[0002] Excessive physical burden: Heavy lead aprons (lead equivalent ≥0.5 mm Pb) often weigh more than 7 kg. Wearing them for a long time can easily cause muscle strain, lumbar spine disease and fatigue accumulation, affecting surgical efficiency and health.

[0003] (2) Shortcomings of screen-type protective devices Limited protection area: Fixed screens cannot dynamically adapt to the displacement of the operating table and the rotation of the C-arm of the imaging machine. Their rigid structure cannot be flush with the operating table, and the blind spot of shielding leads to leakage of scattered radiation.

[0004] Lack of dose monitoring: Existing protection plans lack real-time radiation dose detection capabilities, making it impossible for medical staff to quantify and assess the effectiveness of protection and to take enhanced measures for high-risk areas.

[0005] Therefore, a mobile medical radiation protection device is needed to solve the problems of poor radiation protection and difficulty in detecting radiation dose in existing technologies. Summary of the Invention

[0006] To address the hazards of radiation scattering and wearing heavy lead aprons during radiological diagnosis and treatment, this invention reduces radiation hazards by dividing the commonly used work areas of medical staff in the operating room into radiation protection zones using lead-containing materials. The lead curtains in front and hanging lead curtains are fitted to the operating table to block radiation emanating from gaps, while the radiation dose in the scattering zone and the protection zone is monitored in real time.

[0030] Please see Figures 1-9 This invention provides a mobile medical radiation protection device, comprising an L-shaped bracket 1, a main frame 4 fixed to one side of the top surface of the L-shaped bracket 1, a transparent lead plate 41 fixed to the inner wall of the main frame 4, a radiation protection zone detector 5 and a display screen 45 fixed to the top of one side of the transparent lead plate 41, a radiation zone detector 8 fixed to the top of the other side of the transparent lead plate 41, a lead curtain fixing rod 43 fixed to the bottom of one side of the main frame 4, an L-shaped lead curtain 2 fixed to the inner wall of the lead curtain fixing rod 43, a front transparent lead plate 9 fixed to the other side of the top surface of the L-shaped bracket 1, a left transparent top lead plate 44 fixed to the top surface of the main frame 4, a hanging frame 6 provided on one side of the main frame 4, and a hanging lead curtain 7 provided on one side of the hanging frame 6. The radiation protection zone detector 5 is used to detect the radiation dose within the radiation protection zone, and the radiation zone detector 8 is used to detect the radiation dose in the operating room. The system includes: a suspended frame 6 to block scattered radiation from the C-arm rotation area of ​​the angiography machine and the area above the operating table; a suspended lead curtain 7 to ensure it remains in contact with the patient's body surface during table raising and lowering, effectively blocking scattered radiation from above the operating table; a radiation protection zone detector 5 and a radiation zone detector 8 electrically connected to a display screen 45, allowing real-time observation of the radiation dose detected by the detectors in the radiation protection zone and the radiation zone; an L-shaped lead curtain 2 composed of lead sheeting and nylon cloth for blocking radiation, stitched together, with a sling sewn onto the upper edge; and a lead equivalent of not less than 2.0 mmPb, effectively blocking scattered radiation damage from the bottom left side and the front during interventional radiology procedures.

[0031] In one embodiment, a housing is fixed to the top of one side of the outer wall of the main frame 4, and an upper shaft sleeve 46 is fixed to the middle of the inner wall of the housing. A first fixed shaft 63 is movably connected to one side of the top surface of the upper shaft sleeve 46. A motor 461 is fixed to the bottom surface of the inner wall of the housing. The output end of the motor 461 passes through the upper shaft sleeve 46. Multi-wedge wheels 463 are fixed to the output end of the motor 461 and the top of the outer wall of the first fixed shaft 63, respectively. A multi-wedge belt 462 is movably connected between the two multi-wedge wheels 463. When the suspension frame rotation key 15 is operated, the motor 461 starts and drives the suspension frame 6 to rotate through the transmission of the multi-wedge wheels 463 and the multi-wedge belt 462, thereby causing the transparent suspension lead plate 61 to rotate. The motor 461 and the multi-wedge wheels 463 have a non-locking structure to prevent collision with the C-arm of the contrast machine.

[0032] In one embodiment, the suspension frame 6 includes a suspension frame located on one side of the main frame 4. A transparent suspension lead plate 61 is fixed to the inner wall of the suspension frame 6, and a transparent top lead plate 64 is fixed to the top surface of the suspension frame 6. A limit switch 47 is fixed to the top of the outer side wall of the main frame 4 near the suspension frame 6. A mounting bracket is fixed to the outer side wall of the suspension frame 6 near the outer shell. A first fixed shaft 63 and a second fixed shaft 66 are fixed to the top and bottom surfaces of the mounting bracket, respectively. A lower shaft sleeve 48 is fixed to the middle of the side of the main frame 4 near the suspension frame 6. A bearing is fixed inside the lower shaft sleeve 48. The bottom second fixed shaft 66 is fixed to the inner wall of the bearing. The top first fixed shaft 63 moves through the upper shaft sleeve 46 and is fixed to the bottom surface of the first fixed shaft 63.

[0033] In one embodiment, the limit switch 47 is fixed to the top surface of the fixing block 4700, and the fixing block 4700 is fixed to the inner wall of one side of the main frame 4. The limit switch 47 includes a terminal block 4701, a metal spring 4702, a roller 4703, and a touch switch 4704. During interventional radiology surgery, this product is placed on one side of the operating table, with the front lead curtain 3 flush against the edge of the operating table. Pressing and holding the rotation control key 15 starts the motor 461, which drives the multi-wedge wheel 463, the multi-wedge belt 462, and the suspension frame 6 to rotate. The product rotates until the suspension frame 6 reaches one side of the outer edge. After the wall touches the roller 4703, the roller 4703 pushes the metal spring 4702 to swing and press against the touch switch 4704. When the touch switch 4704 is pressed, the motor 461 is disconnected and powered on, thus stopping the rotation of the suspension frame 6. After the suspension frame 6 is adjusted to be parallel to the operating table, the patient can lie on the operating table. After the doctor controls the operating table to move to the appropriate position, the suspension frame 6 is adjusted to rotate above the operating table by rotating the control key 15. The lifting control key 16 is pressed and held to start the worm motor 621 to drive the synchronous pulley 622 and the synchronous belt 624. The pulley 6291 and the suspended lead curtain 7 move. Once the suspended lead curtain 7 is lowered to be flush with the patient's body, the lifting control button 16 can be released. The motor 461 and the worm gear motor 621 rotate slowly and cannot respond quickly in emergency medical situations where head or chest resuscitation is required. Pressing the lead curtain lifting button 628 will cause the locking spring 6294 and locking pin 6293 to disengage from the tooth groove of the pulley 6291, pushing the suspension rod 62 to cause the pulley 6291 to roll and rise along the synchronous belt 624. Releasing the lead curtain lifting button 628 will lock the pulley 629. 1. Fixed on the toothed groove of the synchronous belt 624, the multi-wedge pulley 463 and the multi-wedge belt 462 are connected by a smooth surface without locking, which can push the suspension frame 6 to the side of the operating table; During the operation, the doctor will control the C-arm of the angiography machine to irradiate the lesion from different angles according to the condition of the patient's lesion. During the rotation or movement of the C-arm, it may interfere with the suspension frame 6 or the swing arm foot 14. The swing arm foot 14 should swing to be parallel to the L-shaped bracket 1 to avoid interference with the bottom of the C-arm. The suspension frame 6 can avoid interference with the top of the C-arm by controlling its rotation.

[0034] The lead equivalent of the transparent suspended lead plate 61, the transparent side lead plate 41, the left transparent top lead plate 44, and the suspended transparent top lead plate 64 is not less than 2.0 mmPb, which can effectively block the scattering damage from the side of the main frame 4 and the top surface of the entire equipment during interventional radiology diagnosis and treatment.

[0035] In one embodiment, side covers 65 are fixed to both sides of one side of the suspension frame 6. Mounting seats 625 are fixed to the top and bottom of one side of the side covers 65. An optical shaft 626 is fixed between the two mounting seats 625. A left movable block 627 and a right movable block 629 are movably connected to the outer wall of the optical shaft 626. A suspension rod is fixed to the side of the two movable blocks near the front transparent lead plate 9. A soft curtain lifting key 16 is fixed to one side of the suspension rod. The suspended lead curtain 7 is fixed to one side of the suspension rod. A worm gear motor 624 performs the lifting motion and a pulley 6291 is used for manual lifting. The worm gear motor 624 is connected to a synchronous pulley 622, and the synchronous pulley 622 is connected to a double-sided synchronous belt 624 for rotation. The double-sided synchronous belt 624 is connected to a pulley 6291 on the outside for manual lifting and lowering. A limiting strip 623 on the inside of the double-sided synchronous belt 624 prevents it from disengaging from the pulley 6291. The pulley 6291 and locking pin 6293 are fixed at both ends of the left movable block 627. By pressing the locking spring 6294, the locking pin 6293 is disengaged from the tooth groove, allowing the pulley 6291 to rotate. The locking spring 6294 is connected to the lead curtain lifting key 628 for manual operation. The right movable block 629 cooperates with the optical axis 626 for linear movement. The pulley 6291 is held in place by the locking pin 6293. Pressing the locking spring 6294 releases the locking pin 6293, allowing for manual lifting and lowering. In cases where patients enter a critical condition during interventional radiology treatment and require immediate resuscitation, the manual lifting function can be used to quickly raise the suspended lead curtain 7 for emergency treatment.

[0036] In one embodiment, a bottom frame is fixed to the left and right ends of the L-shaped bracket 1, and a straight leg 12 is fixed to one side of the bottom frame. A first universal wheel 13 is movably connected to the bottom surface of the straight leg 12. A limiter 17 is fixed to the other side of the bottom frame. A swing arm leg 14 is movably connected inside the limiter 17. A second universal wheel 13 is movably connected to one side of the bottom surface of the swing arm leg 14. A power supply box 11 is fixed to the outer wall of the L-shaped bracket 1. The swing arm leg 14 can stably support the L-shaped bracket 1 on the one hand, and on the other hand, by rotating the swing arm leg 14 left and right, interference from the C-arm of the angiography machine at the bottom of the operating table can be avoided.

[0037] In one embodiment, a hanging frame rotation key 15 and a lead curtain lifting key 16 are provided on the top of one side of the inner wall of the L-shaped bracket 1.
