Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-3, and 7, the present utility model provides a radiation protection device 10 including a body 100. The main body 100 is provided with an operation window 110, a guard 120 and a baffle 130, the guard 120 and the baffle 130 are made of radiation-proof materials, the baffle is positioned at the periphery of the operation window, the operation window 110 is covered by the guard 120, the guard 120 is provided with at least one opening 122, the opening 122 is configured for the arm of an operator to pass through, the baffle is combined with the guard to at least shield the trunk and the head and the neck of the operator, the baffle 130 is provided with a perspective part, and the lead equivalent of the lower part of the main body 100 is larger than that of the upper part of the main body 100.

The following is illustrated by the operator as an example of a sonographer: when the arm of the sonographer passes through the operation window 110 of the radiation protection device 10 to operate medical instruments such as an ultrasonic probe, the baffle 130 and the protection piece 120 are positioned between the radiation source and the operator, so that the injury of radiation rays to the trunk, the limbs, the head and neck of the operator and human tissues including organs, thyroid and eyes positioned therein can be effectively reduced. In addition, the ultrasound probe, patient, etc. can be observed by the ultrasound practitioner through the see-through portion of the baffle 130, and the ultrasound practitioner's hand can extend out of the opening 122 of the guard 120 to facilitate manipulation of the ultrasound probe, without affecting the ultrasound practitioner's operation, the radiation protection device 10 can block radiation from the operator's torso, extremities, head and neck, and the body tissues including organs, thyroid, eyes, etc. located therein, which is advantageous for more comprehensive and effective protection of the ultrasound practitioner.

The main body 100 includes a frame having a substantially rectangular shape. The frame is formed by welding or screw locking of metal materials, wherein the metal materials can be stainless steel, aluminum and other metal materials, and the frame made of the metal materials is convenient for installing the baffle 130 and the guard 120, and can provide larger supporting force for the baffle 130 and the guard 120.

Specifically, in the present embodiment, the frame of the main body 100 is made of stainless steel by welding a square tube.

Further, the outer surface of the frame of the main body 100 may be coated with a soft material such as plastic or the like to reduce injury to the sonographer in case of false impact.

As shown in fig. 3-4, in some embodiments, the operation window 110 is disposed at the middle of the main body 100, the baffle 130 is disposed at a portion of the main body 110 other than the operation window 110, portions of the baffle 130 adjacent to the operation window 110 on both left and right sides of the operation window 110 and a portion above the operation window 110 may be disposed as a perspective portion through which a sonographer located at a side of the main body 110 facing away from the radiation source may observe a surgical target area located at the other side of the main body 100, so that the sonographer can observe an operation to the surgical target area, thereby being able to adjust a position of a handheld medical device or instrument (e.g., an ultrasound probe, etc.) as needed. With the above arrangement, the main body 100 having the shutter 130 can shield the whole body of the operator, and the operation window 110 is located in the arm movement range of the operator.

The baffle 130 may be transparent or partially transparent as a whole, and when the baffle 130 has a partially transparent portion, the transparent portion is made of a transparent material containing lead, and for ease of understanding, the transparent portion on the baffle 130 is taken as a transparent protection plate, and other portions of the baffle 130 are taken as non-transparent protection plates as examples. The barrier 130 has at least 1 transparent shielding plate disposed adjacent to the operation window 110. When the barrier 130 has 2 or more transparent shielding plates, at least 1 transparent shielding plate is disposed adjacent to the operation window 110. Since the arm of the sonographer needs to pass through the operation window 110 during the operation, the head of the sonographer must be positioned around the periphery of the operation window 110 when the arm of the sonographer passes through the operation window 110, and at least one transparent shielding plate is provided around the operation window 110 so that the sonographer can observe the operation target region. At least one transparent shielding plate is located at an upper portion of the main body 100 and is disposed adjacent to the operation window 110, i.e., a perspective portion is at least partially located at an upper portion of the main body 100 and is disposed adjacent to the operation window 110.

The lead equivalent of the lower part of the main body 100 is larger than that of the upper part of the main body 100, and since the radiation source is generally arranged near the lower part of the main body 100, the radiation intensity of the radiation source to the lower part of the main body 100 is larger than that of the radiation source to the upper part of the main body 100, so that the lead equivalent of the upper part of the main body 100 can be lower than that of the lower part of the main body 100, the cost can be reduced, the protective performance of the main body is not influenced, and the protective effect is not reduced. In addition, the height of the main body 100 should not be lower than the height of the sonographer, the height of the main body 100 is generally set to be 1.6m-3.0m, and if the lead equivalent of the lower part of the main body 100 is less than or equal to the lead equivalent of the upper part of the main body 100 on the premise that the main body 100 has the height, the gravity center of the main body 100 is easily unstable, the stable placement of the main body 100 is not facilitated, and if the lead equivalent of the lower part of the main body 100 is greater than the lead equivalent of the upper part of the main body 100, the stability of the gravity center of the main body 100 can be ensured, and the stable position of the main body 100 is maintained. Wherein the lead equivalent of the upper part of the main body 100 or the transparent protective plate is not less than 0.3mmPb, preferably 0.5mmPb-7.0mmPb, more preferably 1.0mmPb-5.0mmPb. In some embodiments, the lead equivalent of the body 100 increases gradually from the upper portion to the lower portion of the body 100, so that the center of gravity of the body 100 is stabilized at the lower portion of the body 100, further facilitating stable placement of the body 100.

The baffle 130 may have a single-layer structure or a multi-layer structure. The baffle 130, which is a high purity lead plate, is positioned at the lower portion of the main body 100, and may be made of 99.99% electrolytic lead. Since too low a lead equivalent may cause deterioration of the barrier performance, and too large a lead equivalent may cause excessive weight of the barrier 130, thereby causing excessive weight of the entire apparatus and inconvenient movement, in the present embodiment, the lead equivalent of the barrier 130 located at the lower portion of the main body 100 is not less than 0.3mmPb, preferably 0.5mmPb-12.0mPb, more preferably 2.0mmPb-6.0mmPb. When the baffle 130 has a multi-layer structure, the inner layer of the baffle 130 is a lead plate, and the outer layer can be made of metal plates such as stainless steel, aluminum and the like, so that the manufacturing cost can be properly reduced while the radiation blocking function is ensured.

In addition, an operating window 110 is provided through the main body 100, and an arm of a sonographer can pass through the operating window 110 to reach the other side of the main body 100 at one side of the main body 100. Thus, when the operator is located at one side of the main body 100, the medical instrument or device (e.g., an ultrasonic probe, etc.) located at the other side of the main body 100 can be operated through the operation window 110.

Since the area of the operation window 110 is too small, the operation range of the operator is limited, and when the area of the operation window 110 is too large, the shielding performance is lowered. Therefore, the size of the operation window 110 in the vertical direction in this embodiment is between 100mm and 700mm, preferably between 200mm and 500 mm; the size of the operating window 110 in the horizontal direction is between 50mm and 800mm, preferably between 200mm and 600 mm.

In another embodiment, as shown in fig. 8-9, the operation window 110 is disposed at the upper portion of the main body 100, the baffle 130 is disposed at a portion of the main body 110 other than the operation window 110, and a portion of the baffle 130 adjacent to the operation window 110 is a perspective portion, by which the sonographer can operate a medical device or instrument having a higher position.

As shown in fig. 10-11, in another embodiment, a cross bar is disposed in the middle of the main body 100, and the cross bar is located below the operation window 110, which may be a part of the frame of the operation window 100 to form the operation window; at the same time, the cross bar can also be used to mount the hand rest support 300, avoiding holes in the baffle 130 to mount the hand rest support 300, thereby further reducing the risk of leakage of radiation rays.

In one embodiment, as shown in FIGS. 5-7, the guard 120 includes at least two sub-guards 121. The adjacent two sub-shields 121 have an overlapping portion where the opening 122 is provided.

In some embodiments, the sub-protection members 121 are made of flexible materials, two adjacent sub-protection members are fixedly connected to each other corresponding to the top of the overlapping portion, two adjacent sub-protection members are fixedly connected to the bottom of the overlapping portion, and two adjacent sub-protection members are not fixedly connected to the middle of the overlapping portion. With the above arrangement, as shown in fig. 6 to 7, the overlapping portion does not expose the opening 122 in a natural state; after the arm of the sonographer is inserted into the middle part of the overlapped part in a straight arm or a bent arm along the horizontal direction, the middle part of the overlapped part is extruded by the arm so as to form an opening 122, and the opening is in a working state; when the sonographer's arm is retracted, the overlapping portion loses force from the arm and returns to a natural state. Therefore, in a natural state, the overlapping portion is not exposed to the opening 122, so that rays can be effectively blocked; in the working state, since the opening 122 is provided in the middle of the overlapping portion, and the upper and lower portions of the overlapping portion have no openings, the exposed area of the overlapping portion can be reduced, thereby reducing the risk of leakage of radiation rays.

In some embodiments, two adjacent sub-shields are fixedly connected to each other corresponding to the top of the overlapping portion, two adjacent sub-shields are fixedly connected to the bottom of the overlapping portion, two adjacent sub-shields are not fixedly connected to the middle of the overlapping portion, and the overlapping portion exposes the opening 122 in a natural state. Specifically, the side of the overlapping portion facing the operator does not expose the opening 122, and the side of the overlapping portion exposes the opening 122, thereby facilitating the passage of the arm of the operator through the guard 120, the operation window 110 via the opening 122 in the horizontal direction.

It should be noted that the arm of the sonographer can pass through the sub-guard 121 through the opening 122 of the overlapping portion. It will be appreciated that the greater the number of sub-guards 121, the greater the number of openings 122 between the sub-guards 121, thereby enabling the guard 120 to reduce the restriction of the sonographer's arm. Thus, in other embodiments, the number of sub-guards 121 may also be three. The three sub-shields 121 are arranged laterally, and the sub-shield 121 located in the middle is at least partially overlapped with the sub-shields 121 on both sides, respectively. The opening 122 is provided in the overlapping portion for the arm of the sonographer to pass through.

It should be noted that, in the present utility model, the length L of the guard 120 is not less than the dimension of the operation window 110 in the vertical direction, and the width W of the guard 120 is not less than the dimension of the operation window 110 in the horizontal direction. Therefore, the area of the shielding member 120 can be larger than the area of the operation window 110, so that the shielding member 120 can completely cover the operation window 110, and accidents of radiation source radiation to a sonographer caused by gaps between the shielding member 120 and the operation window 110 are avoided.

In general, the length L of the guard 120 should be at least 10mm greater than the dimension of the operating window 110 in the vertical direction; the width W of the guard 120 should be at least 5mm greater than the dimension of the operating window 110 in the horizontal direction. Preferably, the length L of the guard 120 exceeds the dimension of the operating window 110 in the vertical direction by a range between 20mm and 70 mm; the width W of the guard 120 exceeds the dimension of the operating window 110 in the horizontal direction by a range of between 10mm and 100 mm.

Further, the shielding member 120 is used to prevent radiation from being emitted to the sonographer through the operation window 110, and the opening 122 of the shielding member 120 allows the arm of the sonographer to pass through, so that the shielding member 120 has the function of shielding the radiation and is flexible. Specifically, in the present embodiment, the guard 120 is made of a flexible material containing lead, preferably lead rubber. In order to ensure a better protection effect of the protection member 120, the protection member 120 should have neat and beautiful appearance, clean surface, uniform color, and no defects such as specks and cracks. The lead equivalent of the shield 120 should be not less than 0.3mmPb, preferably 0.4mmPb to 4.0mmPb, more preferably 0.5mmPb to 2.0mmPb.

In one embodiment, the body 100 is further provided with a fixing member. The fixture is located above the operating window 110. The guard 120 is at least partially connected to the fixture. Accordingly, the guard 120 can be fixed above the operation window 110 by the fixing member. Under the influence of gravity, the rest of the guard 120 can cover the operation window 110 to shield the operation window 110.

Further, as shown in fig. 3 to 5, in one embodiment, the fixing member is a first hanging rod 140, the protection member 120 includes a hanging portion 123, and the protection member 120 is hung on the first hanging rod 140 through the hanging portion 123. The hanging portion 123 includes a first connecting portion 1231 and a second connecting portion 1232, a sliding portion 1233 is disposed between the first connecting portion 1231 and the second connecting portion 1232, and the first connecting portion 1231 is detachably connected with the second connecting portion 1232. When the first connecting portion 1231 is connected to the second connecting portion 1232, the sliding portion 1233 is bent to form a sliding channel, the axial direction of the sliding channel is parallel to the length direction of the first hanging rod 140, and the first hanging rod 140 is disposed in the sliding channel. The hanging portion 123 can drive the guard 120 to move laterally along the first hanging rod 140, and the body of the hanging portion 123 is made of flexible material, so as to facilitate bending and folding.

Specifically, in one embodiment, as shown in fig. 5, the first connection part 1231 is a female magic tape, and the second connection part 1232 is a male magic tape. When in use, the primary hook and loop fastener is adhered and combined with the primary hook and loop fastener around the first hanging rod 140, and a certain interval is arranged between the primary hook and loop fastener and the primary hook and loop fastener before the primary hook and loop fastener is adhered, and the interval forms a sliding part 1233 after the primary hook and loop fastener and the primary hook and loop fastener are adhered together. When the hanging portion 123 is hung on the first hanging rod 140, the sliding portion 1233 forms a curved sliding channel, and the first hanging rod 140 is disposed in the sliding channel. Thus, by this arrangement, the guard 120 can be made to move laterally along the first hanger bar 140.

In another embodiment, the first connecting portion 1231 is a sub-buckle, and the second connecting portion 1232 is a female buckle. The hanging portion 123 may be hung on the first hanging bar 140 by the snap-fit of the sub-buckle and the main buckle.

Further, in another embodiment, the first connection part 1231 is a first chain and the second connection part 1232 is a second chain. The second chain is provided with a zipper head, so that the first chain, the second chain and the zipper head form a zipper unit. The slider may connect or disconnect the first and second links. After the first chain is wound on the first hanger bar 140, the guard 120 may be hung on the first hanger bar 140 by controlling the slider so that the first chain and the second chain are connected.

In one embodiment, the hanging portion 123 is a hanger to hang directly on a hanger bar. In another embodiment, the hanging portion 123 is a magnetic patch, and the first hanging rod 140 is a magnetic rod. The first hanging rod 140 can be made of magnetic materials, and the first hanging rod 140 can be made to be magnetic through a mode of built-in magnets. Accordingly, the magnetic paste and the magnetic rod are combined under the magnetic force, so that the hanging part 123 is hung on the first hanging rod 140.

In one embodiment, as shown in fig. 1-2 and 12-13, the radiation protection device 10 further includes a stand 200, one end of the stand 200 is fixedly connected to the bottom of the main body 100, and a roller assembly 210 is connected to the bottom side of the stand 200. The foot stand 200 can be driven by the roller assembly 210 to drive the main body 100 to move, so as to facilitate moving the radiation protection device 10 to a proper position.

It should be noted that, the stand 200 is provided with a first fixing hole 220 and a connecting member 230, and the connecting member 230 extends in a vertical direction. Wherein, screws, pins, welding rods, etc. may be used to pass through the first fixing holes 220 to fixedly connect the stand 200 to the bottom of the main body 100. Therefore, the foot stool 200 and the main body 100 may be fixedly connected by at least one of screwing, welding, riveting and crimping. The roller assembly 210 is connected to the connecting member 230, and specifically, the connecting member 230 further has a mounting portion extending along a horizontal direction, and the connection manner between the roller assembly 210 and the mounting portion of the stand 200 may be at least one of screwing, welding, riveting, and crimping. Specifically, in the present embodiment, the stand 200 is screwed with the main body 100, and the roller assembly 210 is screwed with the stand 200, so as to facilitate the disassembly and replacement of the stand 200 and the roller assembly 210.

Further, as shown in fig. 12 to 13, the roller assembly 210 includes a braking portion 211 and a roller 212, and the braking portion 211 may limit the rotation of the roller 212. Wherein, the main body 100 can be driven to move by the rotation of the roller 212. As shown in fig. 13A, in a natural state, the braking portion 211 is not in contact with the roller 212, and at this time, the roller 212 can be rotated freely by an external force, so that the body 100 can be moved. As shown in fig. 13B, in the braking state, the braking portion 211 abuts against the roller 212 to limit the rotation of the roller 212, thereby preventing the movement of the main body 100.

The braking portion 211 is rotatable relative to the stand 200: in the natural state, the roller assembly 210 may be shifted from the natural state to the braking state by depressing the pressing part 211; in the braking state, the roller assembly 210 can be shifted from the braking state to the natural state by pulling up the braking portion 211.

In one embodiment, as shown in FIGS. 1-2 and 14-15, radiation protection device 10 further includes a hand rest cradle 300. The hand rest bracket 300 is positioned below the operation window 110 and fixedly connected with the main body 100. When in use, the sonographer can place the arm on the hand support bracket 300 so as to avoid fatigue and ache caused by long-time suspension of the arm, thereby being beneficial to providing a more comfortable operation environment for the sonographer and facilitating smooth operation.

Further, in one embodiment, as shown in fig. 14-15, the hand rest bracket 300 includes a first fixing plate 310, a first adjusting arm 320, a first rotating arm 330, and a hand rest plate 340. The first fixing plate 310 is fixedly connected to the main body 100, one end of the first adjusting arm 320 is rotatably connected to the first fixing plate 310, the other end of the first adjusting arm 320 is rotatably connected to one end of the first rotating arm 330, and the other end of the first rotating arm 330 is rotatably connected to the hand rest 340.

The first rotating portion 350 is disposed between the first fixing plate 310 and the first adjusting arm 320. The first rotating part 350 can drive the first adjusting arm 320 to move the first rotating arm 330 in a vertical direction (Y-axis direction), so that the position of the first rotating arm 330 in the vertical direction can be adjusted. Specifically, the first rotation part 350 can rotate the first adjusting arm 320 by an angle of 0 to 180 ° in the vertical direction. The first rotating part 350 has a plurality of gears, and can be positioned when rotated to the corresponding gears. In some embodiments, the first rotating part 350 has 7 gears, and the first rotating part 350 is rotated to one of 0 °, 30 °, 60 °, 90 °, 120 °, 150 ° and 180 ° and can be positioned, and the first adjusting arm 320 is kept stationary in the absence of an external force acting on the first rotating part 350.

It should be noted that, a second rotating portion 360 is disposed between the first adjusting arm 320 and the first rotating arm 330. The second rotating portion 360 can drive the first rotating arm 330 to rotate in a horizontal direction (X-axis direction) to adjust the position of the first rotating arm 330 in the horizontal direction. Specifically, the second rotating part 360 can rotate the first rotating arm 330 by an angle of 0 to 180 ° in the horizontal direction (X-axis direction). The second rotating part 360 has a plurality of gears, and can be positioned when rotated to the corresponding gears. In some embodiments, the second rotating part 360 has 7 gears, and the second rotating part 360 is rotated to one of 0 °, 30 °, 60 °, 90 °, 120 °, 150 °, and 180 °, and the first rotating arm 330 is kept stationary in the absence of an external force acting on the second rotating part 360.

It should be noted that a third rotating portion 370 is provided between the first rotating arm 330 and the hand rest 340. The third rotating portion 370 can drive the hand rest 340 to rotate in the horizontal direction, so that the posture of the arm can be adjusted according to the needs and preference of the sonographer when the sonographer places the arm on the hand rest 340. Specifically, the third rotating portion 370 can rotate the hand rest 340 by 0 to 360 ° in the horizontal direction (X-axis direction). The third rotation portion 370 has a plurality of gears, and is positionable when rotated to the corresponding gear. In some embodiments, the third rotation portion 370 has 12 gear positions, and the third rotation portion 370 is rotated to one of 0 ° (360 °), 30 °, 60 °, 90 °, 120 °, 150 °, 180 °, 210 °, 240 °, 270 °, 300 °, and 330 °, where the hand rest 340 remains stationary without an external force acting on the third rotation portion 370.

Further, as shown in fig. 15, a concave region 341 is provided on the hand rest 340. The recessed region 341 is configured for placement of the arm by the sonographer. The hand rest 340 has a structure in which both sides are high and the middle is low to form the concave region 341, and both sides thereof are outwardly expanded in a direction away from the middle. Therefore, when the arm of the surgeon touches one side of the concave region 341, the arm can be placed in the concave region 341 along the concave shape of the concave region 341, without observing the position of the concave region 341, and the sonographer can blindly place the arm in the concave region 341, which is beneficial to improving the use efficiency. Maintaining the first rotating arm 330 parallel to the horizontal direction ensures that the recessed area 341 of the hand rest 340 is recessed downward, i.e., recessed opening is facing upward, facilitating placement of the arm of the sonographer to provide support for the sonographer's arm.

It will be appreciated that the recessed region 341 may be provided with a soft padded silicone or an outer cloth to enhance the comfort of the sonographer.

It should be noted that, when the adjustment range of the hand support 300 is too large, on one hand, the weight of the entire hand support 300 is increased to affect the firmness, and on the other hand, the adjustment difficulty is increased due to the overweight of the hand support 300, which is not beneficial to the operation; when the adjustment range of the hand support 300 is too small, the hand support 300 will limit the arm movement range of the surgeon, which is not beneficial to the operation. Thus, the adjustment range of the hand rest 340 in the vertical direction is between 0-200mm, the adjustment range in the horizontal direction is between 0-600mm, preferably the adjustment range of the hand rest 340 in the vertical direction is between 0-100mm, and the adjustment range in the horizontal direction is between 0-400 mm. The hand support bracket 300 is not too heavy on one hand in the adjustment section, so that the operation flexibility of the hand support bracket is ensured; on the other hand, the movement range of the arm of the operator is not limited.

In one embodiment, as shown in FIGS. 1-2 and 16-18, radiation protection device 10 further includes a hanger 400. The hanger 400 is rotatably coupled to the main body 100. The hanger 400 includes a second hanger bar 410, a rotating block 420, and a fixing member 430, wherein the fixing member 430 includes a second fixing plate and two spaced side plates vertically connected to the second fixing plate. One end of the second hanging rod 410 is connected to the rotating block 420, the rotating block 420 is rotatably connected to the fixing member 430, and a side surface of the second fixing plate, which is away from the rotating block 420, is fixedly connected to the main body 100. Wherein, a rotating shaft is arranged between the rotating block 420 and the fixed connection member 430, so that the rotating block 420 can rotate by 0-90 degrees relative to the fixed connection member 430 around the rotating shaft. Wherein, the second hanging rod 410 has an operating state and a natural state. When the second hanging rod 410 is in the working state (the hanging frame 400 is also in the working state at this time), the free end of the second hanging rod 410 is located at a position far from the main body 100, namely, the working position; when the second hanger 410 is in a natural state (at this time, the hanger 400 is also in a natural state), the free end of the second hanger 410 is located near the main body 100, i.e., in a natural position. When the hanger 400 is in the working state, the included angle between the second hanging rod 410 on the hanger 400 and the vertical direction is an acute angle or a right angle. It is understood that, in the working state, when a medical device such as an ultrasonic probe or a catheter is placed on the hanger 400, the medical device can be prevented from sliding off the hanger 400 and falling to the ground due to the gravity.

In the natural state of the second hanging rod 410, a magnet mounting position is provided on a side of the rotating block 420 facing the fixed frame. The first magnet 421 is fixed in the magnet mounting position to be fixedly connected with the rotating block 420. The second fixing plate is made of a metal material, so that the first magnetic block 421 and the second fixing plate can be attracted to each other by magnetic force, so that the second hanging rod 410 is kept vertical. When the second hanging rod 410 is needed, the external force can overcome the magnetic force between the first magnetic block 421 and the second fixing plate to rotate the second hanging rod 410 to the working position.

Further, in one embodiment, as shown in fig. 17, the rotating block 420 is provided with an arc surface 422, a first abutment surface 423, and a second abutment surface 424, the first abutment surface 423 is perpendicular to the second abutment surface 424, and two ends of the arc surface 422 are connected to the first abutment surface 423 and the second abutment surface 424, respectively. In the process of rotating the rotating block 420, the arc surface 422 can avoid the contact between the rotating block 420 and the fixed connection member 430, so as to avoid the interference of the fixed connection member to the rotation of the rotating block 420, which is beneficial to enhancing the rotation flexibility of the rotating block 420.

In addition, when the hanger 400 is in a natural state, the second contact surface 424 contacts with a side of the fixing member 430 facing the rotating block 420; when the hanger 400 is in the working state, the first abutting surface 423 abuts against the side of the fixing member 430 facing the rotating block 420 to limit the rotating block 420 to rotate continuously, so that the rotating block 420 and the second hanging rod 410 are kept horizontal, and the reliability of the second hanging rod 410 in use is further enhanced.

The second fixing plate is provided with a second fixing hole 431. The fastening member 430 may be fixedly coupled to the main body 100 through the second fixing hole 431 by means of screw connection, pin connection, or the like. Of course, the fixing member 430 may be fixedly connected to the frame by a fastening manner, and the fixing manner is various and will not be described herein. The second fixed plate is provided with the second magnetic block 432 on one side away from the rotating block 420, and the magnetism of the second magnetic block 432 is different from that of the first magnetic block 421, so that in a natural state, the second magnetic block 432 and the first magnetic block 421 are attracted to each other, the second hanging rod 410 can be prevented from suddenly dropping, and the stability of the second hanging rod 410 in the natural state is further enhanced.

In one embodiment, as shown in FIGS. 1-2 and 19-20, radiation protection device 10 further includes a suspension bracket 500. One end of the hanging bracket 500 is connected to the main body 100, and the other end of the hanging bracket 500 is used for hanging the display 600.

The fourth rotating part 550 can drive the second rotating arm 520 to rotate 0-180 ° in the horizontal direction (X-axis direction), so that the position of the second rotating arm 520 in the horizontal direction (X-axis direction) can be adjusted. The fourth rotating part 550 has a plurality of gears, and can be positioned when rotated to the corresponding gears. In some embodiments, the fourth rotating part 550 has 7 gears, and the fourth rotating part 550 is rotated to one of 0 °, 30 °, 60 °, 90 °, 120 °, 150 ° and 180 ° to be positionable, and the second rotating arm 520 is kept stationary in the absence of an external force acting on the fourth rotating part 550.

The fifth rotating part 560 can drive the second adjusting arm 530 to move the hanger plate 540 in the vertical direction (Y-axis direction), so that the position of the hanger plate 540 in the vertical direction (Y-axis direction) can be adjusted. Specifically, the fifth rotating part 560 can rotate the second adjusting arm 530 by an angle of 0 to 180 ° in the vertical direction. The fifth rotating part 560 has a plurality of gears, and can be positioned when rotated to the corresponding gear. In some embodiments, the fifth rotating part 560 has 7 gears, and the fifth rotating part 560 is rotated to one of 0 °, 30 °, 60 °, 90 °, 120 °, 150 ° and 180 ° to be positionable, and the second regulating arm 530 is kept stationary in the gears without an external force acting on the fifth rotating part 560.

The sixth rotating part 570 can drive the hanger plate 540 to rotate 0-270 ° in the horizontal direction (X-axis direction), so that the position of the hanger 123 in the horizontal direction (X-axis direction) can be adjusted. The sixth rotating portion 570 has a plurality of gears, and can be positioned when rotated to the corresponding gears. In some embodiments, the sixth rotating part 570 has 10 gears, and the fifth rotating part 560 is rotated to one of 0 °, 30 °, 60 °, 90 °, 120 °, 150 °, 180 °, 210 °, 240 °, and 270 °, and the hanger plate 540 is kept stationary without an external force acting on the sixth rotating part 570. Therefore, by the above arrangement, the position of the display 600 mounted on the hanger plate 540 in space can be conveniently adjusted, which is convenient for the surgeon to adjust to a proper position for viewing.

Further, a wire slot may be disposed in the second rotating arm 520 and the second adjusting arm 530 for the power line and the signal line required by the display screen to pass through.
