[0065] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Among them, the X direction is the thickness direction, the Y direction is the height direction, the Z direction is the width direction, the XY plane is a vertical plane, the XZ plane is a horizontal plane, and the YZ plane is another vertical plane and is perpendicular to the XY plane.

[0066] like Figure 1 -3, the first embodiment of the present invention provides a radiation protection device 10, including a main body 100, and a hanger 4010 is provided on the main body 100. The hanger 4010 includes a hanging rod 4011, a rotating part 4015 and a first fixing member 4012, one end of the hanging rod 4011 is connected to one end of the rotating part 4015, the other end of the rotating part 4015 is connected to the first fixing member 4012, and the end 4014 of the first fixing member 4012 facing away from the hanging rod 4011 is connected to the main body 100; wherein the rotating part 4015 can rotate in at least two planes in the first fixing member 4012, thereby driving the hanging rod 4011 to rotate in at least two planes.

[0067] Specifically, the first fixing member 4012 is provided with a groove, and the groove can be used to accommodate the rotating part 4015, and the shape of the groove is adapted to the shape of the rotating part 4015, so that the rotating part 4015 can rotate in the groove. Generally, the shape of the groove can be hemispherical or hemispherical or other similar shapes, and the shape of the rotating part can be spherical or ellipsoidal or other similar shapes. One end of the hanging rod 4011 is fixedly connected to the rotating part 4015, so that the hanging rod 4011 can be driven to rotate when the rotating part 4015 rotates. Through the above arrangement, the hanging rod 4011 can rotate on the XY plane, the YZ plane or the XZ plane, and can also rotate on the XY plane, the XZ plane and the YZ plane at the same time, so the operator can adjust the position of the hanging rod 4011 according to actual needs. A plurality of fixing holes are provided on the end 4014, and the end 4014 can be fixedly connected to the main body 100 through the fixing holes by means of screw connection, pin connection, etc. Of course, the end portion 4014 may also be fixedly connected to the main body 100 by snap-fitting or the like. The fixing method is prior art and will not be described in detail here.

[0068] The hanging rod 4011 has a working state and a natural state. When the hanging rod 4011 is in the working state (the hanger 4010 is also in the working state at this time), the free end of the hanging rod 4011 is located at a position away from the main body 100, that is, the working position; when the hanging rod 4011 is in the natural state (the hanger 4010 is also in the natural state at this time), the free end of the hanging rod 4011 is located at a position close to the main body 100, that is, the natural position. When the hanger 4010 is in the working state, the angle between the hanging rod 4011 on the hanger 4010 and the Y direction is an acute angle or a right angle. It can be seen that in the working state, when medical equipment such as an ultrasound probe or medical devices such as a catheter are placed on the hanger 4010, it can be prevented that the medical devices slip off the hanger 4010 and fall to the ground due to gravity.

[0069] Further, in some embodiments, the first fastening member 4012 is provided with an opening 4013, and the size of the opening 4013 in the X direction is larger than the size of the hanging rod 4011 in the X direction, so that the hanging rod 4011 can be located in the opening 4013, and the hanging rod 4011 is in a natural state. When the hanging rod 4011 is not needed, the hanging rod 4011 can be adjusted to the Y direction, and the opening 4013 can accommodate the hanging rod 4011, so that the hanging rod 4011 shrinks in the Z direction or the X direction to reduce the width or thickness of the radiation protection device 10 as a whole in the Z direction or the X direction.

[0070] like Figure 4AAs shown, in some embodiments, a magnet 4015a is provided at one end of the rotating portion 4015 of the hanger 4010a close to the hanging rod 4011, and a magnet 4017 is provided at one side of the opening 4013 close to the main body 100 of the first fixing member 4012, and the magnets 4015a and 4017 have different magnetic properties. When the hanging rod 4011 is located in the opening 4013 (that is, the hanging rod 4011 is in a natural state), the magnet 4015a approaches the magnet 4017 and attracts each other, and the hanging rod 4011 can be positioned in the opening 4013 without the action of external force. That is to say, in the natural state, the magnet 4015a and the magnet 4017 attract each other, which can prevent the hanging rod 4011 from falling suddenly, and further enhance the stability of the hanging rod 4011 in the natural state. In addition, the bracket 4010a is further provided with a snap-fitting portion 4018, which is disposed on a side of the end portion 4014 away from the first fixing member 4012 and is fixedly connected to the end portion 4014. A plurality of snap-fitting grooves 101 (such as Figure 4F As shown in FIG. 1 , the engaging portion 4018 is adapted to the engaging groove 101 in shape, and the two can be engaged to fix the hanger 4010a on the main body 100. When the height of the hanging rod 4011 in the Y direction needs to be adjusted, the engaging portion 4018 is removed from the engaging groove 101 on the main body 100, and then after adjusting it to a suitable height, the engaging portion 4018 is inserted into the corresponding engaging groove 101 to form an engaging fit, and the height adjustment of the hanging rod 4011 in the Y direction can be completed.

[0071] like Figure 4B-4C As shown, in some embodiments, in the Z direction, the lower half of the first fixing component 4012a of the bracket 4010b protrudes more than the upper half of the first fixing component 4012a, and after the hanging rod 4011 abuts against the lower half of the first fixing component 4012a during the rotation process, the hanging rod 4011 is blocked by the lower half of the first fixing component 4012a and cannot continue to rotate in the direction opposite to the Y direction (i.e., the direction of gravity), but the hanging rod 4011 can rotate in other directions. Therefore, when the hanger 4010b is in working condition, the hanging rod 4011 abuts against the lower half of the first fixing component 4012a, and the lower half of the first fixing component 4012a provides support for the hanging rod 4011; after the operator places the medical device on the hanging rod 4011, the lower half of the first fixing component 4012a supports the hanging rod 4011 to prevent the hanging rod 4011 from rotating along the direction of gravity and causing the medical device to fall, thereby ensuring the reliability of the hanging rod 4011 in the working condition.

[0072] like Figure 4D-4EAs shown, in some embodiments, the first fixing member 4012b of the hanger 4010c is provided with at least two openings 4013 on the YZ plane and the XZ plane respectively, and the openings 4013 are constructed as guide grooves of the hanging rod 4011, and the hanging rod 4011 can rotate back and forth in the plurality of openings 4013. When the hanging rod 4011 rotates in the openings 4013, the side walls of the first fixing member 4012b forming the openings 4013 restrict the rotation of the hanging rod 4011; therefore, after the medical device is placed on the hanging rod 4011, due to the restriction of the openings 4013, even if a heavier medical device is placed on the hanging rod 4011, the hanging rod 4011 can only rotate in the direction of the openings 4013, and will not randomly shake in other directions, so that the hanging rod 4011 can be prevented from rotating from the target position to other positions, thereby ensuring the safety of the operation. When the hanging rod 4011 is in the opening 4013 on the XZ plane, the side wall of the opening 4013 formed in the first fixing member 4012b provides support for the hanging rod 4011, which can prevent the hanging rod 4011 from rotating along the direction of gravity and causing the medical device to fall, thereby ensuring the reliability of the hanging rod 4011 in the working state.

[0073] like Figure 1 As shown, the main body 100 is also provided with an operation window (not shown in the figure), a protective member 120, and a baffle 130. The protective member 120 and the baffle 130 are made of radiation protection material. The baffle 130 is located at the periphery of the operation window, and the operation window is covered by the protective member 120. The protective member 120 is provided with at least one opening (not shown in the figure), and the opening is configured for the operator's arm to pass through. The baffle 130 combined with the protective member 120 can at least block the operator's torso and head and neck. The baffle 130 has a transparent part, and 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.

[0074] When the operator's arm passes through the operating window of the radiation protection device 10 to operate medical equipment such as an ultrasonic probe, the baffle 130 and the protective member 120 are located between the radiation source and the operator, which can effectively reduce the damage of radiation to the operator's trunk, limbs, head and neck, and human tissues including organs, thyroid gland, eyes, etc. located therein. In addition, the operator can observe the ultrasonic probe, the patient, etc. through the transparent part of the baffle 130, and the operator's hand can be extended from the opening of the protective member 120 to facilitate the operation of the ultrasonic probe. Under the premise of not affecting the operator's surgery, the radiation protection device 10 can block radiation from irradiating the operator's trunk, limbs, head and neck, and human tissues including organs, thyroid gland, eyes, etc. located therein, which is conducive to more comprehensive and effective protection of the operator.

[0075] It should be noted that the main body 100 includes a frame, which is roughly rectangular. The frame is formed by welding or threaded connection of metal materials, and the material can be metal materials such as stainless steel and aluminum. The frame made of metal materials is convenient for installing the baffle 130 and the protective member 120, and can also provide greater support for the baffle 130 and the protective member 120.

[0076] Specifically, in this embodiment, the frame of the main body 100 is made of stainless steel square tubes welded together. The outer surface of the frame of the main body 100 may be coated with a soft material, such as plastic, to reduce the damage to the operator when the operator accidentally hits it.

[0077] The baffle 130 can be transparent as a whole or partially transparent. When the baffle 130 has a partially transparent part, the transparent part is made of a transparent material containing lead. For ease of understanding, the following is an example in which the transparent part on the baffle 130 is a transparent protective plate and the other parts of the baffle 130 are non-transparent protective plates. The baffle 130 has at least one transparent protective plate, which is arranged adjacent to the operation window. When the baffle 130 has two or more transparent protective plates, at least one transparent protective plate is arranged adjacent to the operation window. Since the operator's arm needs to pass through the operation window during the operation, the operator's head must be around the operation window when the operator's arm passes through the operation window. At least one transparent protective plate is arranged around the operation window to facilitate the operator to observe the surgical target area. Therefore, at least one transparent protective plate is located at the upper part of the main body 100 and is arranged adjacent to the operation window, that is, the transparent part is at least partially located at the upper part of the main body 100 and is arranged adjacent to the operation window.

[0078] 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. 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 greater than the radiation intensity of the radiation source to the upper part of the main body 100. Therefore, the lead equivalent of the upper part of the main body 100 can be lower than the lead equivalent of the lower part of the main body 100, which can reduce the cost, and at the same time will not affect its protective performance and will not reduce the protective effect. In addition, the height of the main body 100 should not be lower than the height of the operator. The height of the main body 100 is generally set to 1.6m-3.0m. Under the premise that the main body 100 has the above height, 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, it is easy to cause the center of gravity of the main body 100 to be unstable, which is not conducive to the stable placement of the main body 100. However, 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, it can ensure the stability of the center of gravity of the main body 100 and keep the position of the main body 100 stable. The lead equivalent of the upper part of the main body 100 or the transparent protective plate is not less than 0.3 mmPb, preferably 0.5 mmPb-7.0 mmPb, and more preferably 1.0 mmPb-5.0 mmPb. In some embodiments, the lead equivalent of the main body 100 gradually increases from the upper part to the lower part of the main body 100, so that the center of gravity of the main body 100 is stabilized at the lower part of the main body 100, which is further conducive to the stable placement of the main body 100.

[0079] The baffle 130 can be a single-layer structure or a multi-layer structure. The baffle 130 located at the bottom of the main body 100 is a high-purity lead plate, which can be made of 99.99% electrolytic lead. Since too low a lead equivalent will lead to a decrease in protective performance, and too large a lead equivalent will cause the baffle 130 to be too heavy, resulting in the entire device being too heavy and inconvenient to move, in this embodiment, the lead equivalent of the baffle 130 located at the bottom of the main body 100 is not less than 0.3 mmPb, preferably 0.5 mmPb-12.0 mPb, and more preferably 2.0 mmPb-6.0 mmPb. When the baffle 130 is 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 and aluminum, so as to appropriately reduce the production cost while ensuring the radiation blocking function.

[0080] In addition, the operation window is set through the main body 100, and the operator's arm can pass through the operation window on one side of the main body 100 to reach the other side of the main body 100. Therefore, when the operator is on one side of the main body 100, the medical device or equipment (such as an ultrasound probe, etc.) on the other side of the main body 100 can be operated through the operation window.

[0081] If the area of ​​the operation window is too small, the operator's operating range will be limited, and if the area of ​​the operation window is too large, the protection performance will be reduced. Therefore, the size of the operation window in the vertical direction of this embodiment is between 100mm-700mm, preferably between 200mm-500mm; the size of the operation window in the horizontal direction is between 50mm-800mm, preferably between 200mm-600mm.

[0082] It should be noted that the length of the protective member 120 in the present invention is not less than the size of the operating window in the Y direction, and the width of the protective member 120 is not less than the size of the operating window in the Z direction. Therefore, the area of ​​the protective member 120 can be made larger than the area of ​​the operating window, thereby ensuring that the protective member 120 can completely cover the operating window, thereby avoiding accidents in which the radiation source irradiates the operator due to the gap between the protective member 120 and the operating window.

[0083] Generally speaking, the length of the protective member 120 should be at least 10 mm greater than the size of the operating window in the Y direction; the width of the protective member 120 should be at least 5 mm greater than the size of the operating window in the Z direction. Preferably, the length of the protective member 120 exceeds the size of the operating window in the Y direction by 20 mm to 70 mm; the width of the protective member 120 exceeds the size of the operating window in the Z direction by 10 mm to 100 mm.

[0084] Furthermore, the function of the protective member 120 is to prevent radiation from irradiating the operator through the operating window, and the opening on the protective member 120 allows the operator's arm to pass through. Therefore, the protective member 120 should have the function of blocking radiation and be flexible. Specifically, in the present embodiment, the protective member 120 is made of a flexible material containing lead, preferably lead rubber. In order to ensure that the protective member 120 has a good protective effect, the appearance of the protective member 120 should be neat and beautiful, the surface should be clean, the color should be uniform, and there should be no defects such as scratches and cracks. The lead equivalent of the protective member 120 should not be less than 0.3 mmPb, preferably 0.4 mmPb-4.0 mmPb, and more preferably 0.5 mmPb-2.0 mmPb.

[0085] In one embodiment, Figure 1 As shown, the radiation protection device 10 further includes a tripod 200, one end of which is fixedly connected to the bottom of the main body 100, and a roller assembly is connected to the bottom side of the tripod 200. The tripod 200 can drive the main body 100 to move under the drive of the roller assembly, so as to facilitate moving the radiation protection device 10 to a suitable position.

[0086] Embodiment 2:

[0087] like Figure 5-7As shown, the difference between the second embodiment and the first embodiment is only the hanging bracket.

[0088] Specifically, the hanger 4020 is rotatably connected to the main body 100. The hanger 4020 includes a hanger rod 4021, a rotating portion 4022, a first fixing member 4023 and a second fixing member 4024. The first fixing member 4023 is a U-shaped or quasi-U-shaped structure, which includes a first fixed plate 40231 and two side plates 40232 vertically connected to the first fixed plate 40231 and spaced from each other. One end of the hanger rod 4021 is connected to the rotating portion 4022, and the rotating portion 4022 is rotatably connected to the first fixing member 4023 through a first rotating shaft 4027. The first fixing plate 40231 is rotatably connected to the second fixing member 4024 through a second rotating shaft 4026. The second fixing member 4024 is fixedly connected to the main body 100 on the side facing away from the hanger rod 4021. The first rotating shaft 4027 is arranged parallel to the X direction, so that the rotating part 4022 can rotate 0-90° around the first rotating shaft 4027 relative to the first fixing part 4023 in the YZ plane. Specifically, when the angle between the rotating part 4022 and the XZ plane is 0 or 90°, the rotating part 4022 abuts against the first fixing part 4023, so that the rotating part 4022 cannot continue to rotate in a negative angle or a direction greater than 90°. Therefore, the rotating part 4022 can rotate 0-90° relative to the first fixing part 4023 through the restriction of the first fixing part 4023; the second rotating shaft 4026 is arranged parallel to the Y direction, so that the first fixing part 4023 can rotate around the second rotating shaft 4026 relative to the second fixing part 40 24 rotates 0-180°, specifically, when the angle between the first fixing member 4023 and the XY plane is 0 or 180°, the second fixing member 4024 abuts against the first fixing member 4023, making it impossible for the first fixing member 4023 to continue to rotate along a negative angle or a direction greater than 180°. Therefore, the first fixing member 4023 can be restricted by the second fixing member 4024 to rotate 0-180° relative to the second fixing member 4024; through the above-mentioned arrangement, the rotation directions of the first rotating shaft 4027 and the second rotating shaft 4026 are different, so that the hanging rod 4021 can rotate on the XZ plane or the YZ plane, or on both the XZ plane and the YZ plane at the same time, so the operator can adjust the position of the hanging rod 4021 according to actual needs.

[0089] The hanging rod 4021 has a working state and a natural state. When the hanging rod 4021 is in the working state (the hanger 4020 is also in the working state at this time), the free end of the hanging rod 4021 is located at a position away from the main body 100, that is, the working position; when the hanging rod 4021 is in the natural state (the hanger 4020 is also in the natural state at this time), the free end of the hanging rod 4021 is located at a position close to the main body 100, that is, the natural position. When the hanger 4020 is in the working state, the angle between the hanging rod 4021 on the hanger 4020 and the Y direction is an acute angle or a right angle. It can be seen that in the working state, when medical equipment such as an ultrasound probe or medical devices such as a catheter are placed on the hanger 4020, it can be prevented that the medical devices slip from the hanger 4020 and fall to the ground due to gravity.

[0090] When the hanging rod 4021 is in a natural state, a magnet installation position is provided on one side of the rotating part 4022 facing the first fixing member 4023. The first magnetic block 4028 is fixed in the magnet installation position by a screw 4029 to be fixedly connected with the rotating part 4022. The material of the first fixing plate is a metal material, so the first magnetic block 4028 can attract each other with the first fixing plate through magnetic force, so that the hanging rod 4021 is positioned in a natural position and remains vertical. When the hanging rod 4021 needs to be used, the operator can use external force to overcome the magnetic force between the first magnetic block 4028 and the first fixing plate to rotate the hanging rod 4021 to the working position.

[0091] The second fixing member 4024 is provided with at least one fixing hole, through which the second fixing member 4024 can be fixedly connected to the main body 100 by means of screw connection, pin connection, etc. Of course, the second fixing member 4024 can also be fixedly connected to the main body 100 by means of snap-fitting, etc., which will not be repeated here.

[0092] In addition, the second fixing member 4024 is also provided with a through hole (not shown in the figure), the through hole is provided with a thread and the thread matches the thread of the screw 4025, and the screw 4025 passes through the through hole to abut against the first fixing member 4023. Through the above arrangement, after the first fixing member 4023 is adjusted to a suitable position, the screw 4025 is tightened so that the screw 4025 abuts against the first fixing member 4023, so that the first fixing member 4023 is positioned at the position; when the position of the first fixing member 4023 needs to be adjusted, the screw 4025 is loosened so that the screw 4025 is away from the first fixing member 4023, so that the first fixing member 4023 can be rotated to adjust its position.

[0093] like Figure 8-10As shown, in some embodiments, a plurality of first grooves 40241 are provided at the bottom of the second fixing member 4024a on one side facing the first fixing member 4023a, and an elastic member 40242 is provided at the bottom of the first fixing member 4023a. The first groove 40241 can accommodate an end of the elastic member 40242 away from the first fixing member 4023a, and during the process of rotating the first fixing member 4023a on the XZ plane, the elastic member 40242 can enter or leave the first groove 40241. Specifically, a mounting groove 40233 is provided at the bottom of the first fixing member 4023a, and the elastic member 40242 is disposed in the mounting groove 40233. The elastic member 40242 includes a base 40242a, a spring 40242b and a resistance portion 40242c, one end of the spring 40242b is connected to the base 40242a, and the other end is connected to the resistance portion 40242c, the base 40242a is arranged in the assembly groove 40233 and does not protrude from the assembly groove 40233, and the end of the resistance portion 40242c away from the spring 40242b at least partially protrudes from the assembly groove 40233 when no external force is applied. The elastic member 40242 has a natural state and a compressed state. The natural state is the state of the elastic member 40242 when the spring 40242b is not compressed, that is, the state in which the resistance portion 40242c of the elastic member 40242 is located in the first groove 40241; the compressed state is the state of the elastic member 40242 when the spring 40242b is compressed, that is, the state in which the resistance portion 40242c of the elastic member 40242 is out of the first groove 40241. Through the above-mentioned arrangement, the multiple first grooves 40241 are multiple positioning grooves. When the first fixing component 4023a rotates on the XZ plane, the resistance portion 40242c of the elastic component 40242 can enter the first groove 40241. The resistance portion 40242c, the spring 40242b and the first groove 40241 work together to ensure that the first fixing component 4023a is positioned at the current position on the XZ plane, thereby preventing the hanging rod 4021 from shaking back and forth or swaying due to the shaking of the first fixture 4023a on the XZ plane when the medical device is placed on or removed from the hanging rod 4021.

[0094] like Figure 11-14As shown, in some embodiments, a plurality of opening grooves 40243 are provided on the bottom side of the second fixing member 4024b, and a first protrusion 40221 is provided on a portion of the rotating portion 4022a facing the second fixing member 4024b corresponding to the opening grooves 40243, and the shape of the first protrusion 40221 matches the opening grooves 40243, and the two can form a concave-convex fit. When it is necessary to rotate the first fixing member 4023 on the XZ plane, the rotating portion 4022a is first rotated along the Y direction until the first protrusion 40221 is separated from the opening groove 40243; then the first fixing member 4023 is rotated and adjusted to a suitable position, and the rotating portion 4022a is rotated in the direction opposite to the Y direction until the first protrusion 40221 enters the opening groove 40243. Through the above arrangement, the rotating part 4022a is positioned by using the concave-convex matching method of the first protrusion 40221 and the open groove 40243, which can also prevent the hanging rod 4021 from shaking back and forth and swaying due to the shaking of the first fixing member 4023a on the XZ plane when the medical device is placed on or removed from the hanging rod 4021. In addition, during the concave-convex matching process of the first protrusion 40221 and the open groove 40243, since the first protrusion 40221 abuts against the open groove 40243, the rotating part 4022a cannot rotate in the direction opposite to the Y direction (i.e., the direction of gravity) after the above two abut, so the situation that the hanging rod 4021 rotates in the direction of gravity and causes the medical device to fall due to the excessive weight of the medical device placed on the hanging rod 4021 is avoided, so the reliability of the medical device placed on the hanging rod 4021 can be enhanced, which is conducive to the development of surgery.

[0095] like Fig. 13B , Fig. 13C As shown, further, the thickness of the portion of the first protrusion 40221 close to the rotating portion 4022a in the X direction is X2, and the thickness of the rotating portion 4022a in the X direction is X3. Generally, X2 is 0.1-0.8 times of X3. Through the above arrangement, the first protrusion 40221 will not break and separate from the rotating portion 4022a when subjected to a force in the X direction, which can enhance the stability of the first protrusion 40221. Preferably, X2 is 0.2-0.6 times of X3, and more preferably, X2 is 0.3-0.5 times of X3.

[0096] The thickness of the portion of the first protrusion 40221 away from the rotating portion 4022a in the X direction is X1. Generally, X1 is 0.1-0.5 times of X3. The above arrangement makes the end of the first protrusion 40221 away from the rotating portion 4022a wider and not too sharp. In the process of the concave-convex matching between the first protrusion 40221 and the opening groove 40243, since the end of the first protrusion 40221 away from the rotating portion 4022a is wider, the pressure on the opening groove 40243 by the first protrusion 40221 is smaller, and the opening groove 40243 is not easy to break, thereby avoiding the situation where the opening groove 40243 is squeezed by the first protrusion 40221 and breaks, thereby improving the reliability of the second fixing member 4024b. Preferably, X1 is 0.15-0.4 times of X3, and more preferably, X2 is 0.2-0.35 times of X3.

[0097] The width of the first protrusion 40221 in the Z direction is Z1, the width of the portion of the rotating portion 4022a close to the first protrusion 40221 in the Z direction is Z2, and the width of the portion of the rotating portion 4022a away from the first protrusion 40221 in the Z direction is Z3, wherein Z2 is smaller than Z3, and Z1+Z2≤Z3. Through the above arrangement, the width Z1 of the first protrusion 40221 in the Z direction is small, and the rotating portion 4022a only needs to rotate a small angle on the YZ plane to separate the first protrusion 40221 from the opening groove 40243, so as to facilitate the adjustment of the position of the first fixing member 4023.

[0098] The height of the first protrusion 40221 in the Y direction is Y1, and the height of the rotating portion 4022a in the Y direction is Y2. Generally, Y1 is 0.1-0.5 times of Y2. Similarly, setting Y1 in the above size is conducive to the separation of the first protrusion 40221 from the opening groove 40243, and the pressure on the opening groove 40243 by the first protrusion 40221 is also small. Preferably, Y1 is 0.15-0.4 times of Y2, and more preferably, Y is 0.2-0.35 times of Y2.

[0099] In addition, in some embodiments, the second fastening member 4024 of the second embodiment may also be provided with the engaging portion 4018 as described in the first embodiment, and correspondingly, a plurality of engaging grooves 101 are provided on one side of the main body 100, and the engaging portion 4018 and the engaging groove 101 are adapted in shape, and the two can be engaged to fix the hanger 4020 on the main body 100. When it is necessary to adjust the height of the hanging rod 40121 in the Y direction, the engaging portion 4018 is removed from the engaging groove 101 on the main body 100, and then after adjusting it to a suitable height, the engaging portion 4018 is inserted into the corresponding engaging groove 101 to form an engaging fit, and the height adjustment of the hanging rod 4021 in the Y direction can be completed.

[0100] Embodiment three:

[0101] like Figure 15-20 As shown, the difference between the third embodiment and the first embodiment lies only in the hanger and the connection method between the hanger and the main body 100 .

[0102] Specifically, a plurality of engaging grooves 101 are provided on one side of the main body 100; the hanger 4030 includes a fixing member 4033, a rotating part 4032 and a hanging rod 4031, one end of the hanging rod 4031 is fixedly connected to the rotating part 4032. The rotating part 4032 is provided with a first through hole 4038, the rotating part 4032 is movably connected to the fixing member 4033, and a second protrusion 4039 is provided on the bottom of the rotating part 4032 facing the fixing member 4033. The fixing member 4033 is provided with a second through hole 4037, a plurality of third grooves 4035 and an engaging part 4034 located on a side away from the rotating part 4032, and the rotating shaft 4036 passes through the second through hole 4037 and the first through hole 4038 to connect the rotating part 4032 with the fixing member 4033; the second protrusion 4039 is adapted to the shape of the third groove 4035 so that the two can be engaged. The first through hole 4038 is a slide groove, and its length in the Z direction is larger than the diameter of the rotating shaft 4036. The rotating shaft 4036 can move back and forth on the XZ plane relative to the first through hole 4038, so the rotating part 4032 can move back and forth on the XZ plane relative to the rotating shaft 4036.

[0103] When the position of the hanging rod 4031 on the XZ plane needs to be adjusted, the rotating part 4032 is rotated in a direction away from the fixing part 4033 until the second protrusion 4039 is separated from the third groove 4035, and then the rotating part 4032 is rotated to a suitable position and then rotated in the direction of the fixing part 4033 until the second protrusion 4039 abuts against the third groove 4035. Based on the same principle as the second embodiment, the rotating part 4032 is fixed on the XZ plane by providing the fixing part 4033, and the hanging rod 4031 can be positioned on the XZ plane through the cooperation of the second protrusion 4039 and the third groove 4035, without the hanging rod 4031 shaking on the XZ plane due to external force and causing the medical device to fall.

[0104] When the height of the hanging rod 4031 in the Y direction needs to be adjusted, the engaging portion 4034 of the fixing member 4033 is removed from the engaging slot 101 on the main body 100, and after adjusting it to a suitable height, the engaging portion 4034 is inserted into the corresponding engaging slot 101 to form an engaging fit, and the height adjustment of the hanging rod 4031 in the Y direction can be completed. As for the size relationship between the second protrusion 4039 and the rotating portion 4032, it is the same as that in the second embodiment, and will not be repeated here.

[0105] Embodiment 4:

[0106] like Figure 21-25As shown, the difference between the fourth embodiment and the third embodiment is only the connection method between the bracket and the main body 100.

[0107] Specifically, a plurality of through holes 102 are provided on one side of the main body 100; the hanger 4040 includes a fixing member 4043, a rotating portion 4042 and a hanging rod 4041, and one end of the hanging rod 4041 is fixedly connected to the rotating portion 4042. The rotating portion 4042 is provided with a first through hole 4048, the rotating portion 4042 is movably connected to the fixing member 4043, and a second protrusion 4049 is provided on the bottom of the rotating portion 4042 facing the fixing member 4043. The fixing member 4043 is provided with a second through hole, a plurality of third grooves 4046, a latch 4045, and two connecting parts 4044 located on a side away from the rotating part 4042, each connecting part 4044 is provided with a third through hole 4044a, and the rotating shaft 4047 passes through the first through hole 4038 and the second through hole to connect the rotating part 4042 with the fixing member 4043; the second protrusion 4049 is adapted in shape to the third groove 4046 so that the two can be engaged. The length of the first through hole 4048 in the Z direction is larger than the diameter of the rotating shaft 4047, so the rotating part 4042 can move back and forth on the XZ plane. The proximal end of the latch 4045 is provided with an operating end 4045b, and the distal end of the latch 4045 is provided with a protrusion 4045a, and the operating end 4045b is arranged perpendicularly to the protrusion 4045a, wherein the proximal end of the latch 4045 is close to the operator, and the distal end of the latch 4045 is far away from the operator. The portion of the third through hole 4044a corresponding to the protrusion 4045a is arranged in the Y direction, and when the protrusion 4045a of the latch 4045 is facing the third through hole 4044a, the latch 4045 can pass through the third through hole 4044a; when the protrusion 4045a is not facing the third through hole 4044a, the latch 4045 cannot pass through the third through hole 4044a.

[0108] When the height of the hanging rod 4041 in the Y direction needs to be adjusted, the operating end 4045b of the latch 4045 is rotated in the Z direction so that the protrusion 4045a is located in the Y direction, thereby removing the latch 4045 from the third through hole 4044a and the through hole 102; then, after the hanging rod 4041 is adjusted to a suitable height, the operating end 4045b of the latch 4045 is rotated in the Z direction again, and the protrusion 4045a can pass through the third through hole 4044a. Insert the latch 4045 into the third through hole 4044a and the corresponding through hole 102, then release the operating end 4045b, the operating end 4045b will automatically rotate to the direction opposite to the Y direction (i.e. the direction of gravity) under the action of gravity, thereby driving the protrusion 4045a to rotate to the Z direction, at this time the protrusion 4045a cannot pass through the third through hole 4044a, so the hanging rod 4041 can be fixed at this position, and the height adjustment of the hanging rod 4041 in the Y direction can be completed. As for the size relationship between the second protrusion 4049 and the rotating part 4042, it is the same as that in the second embodiment, and will not be repeated here.

[0109] like Figure 26-27 As shown, in some embodiments, the main body 100 does not need to be provided with a through hole. Specifically, the latch 4045 is replaced by a screw 4045c, and the third through hole 4044a of the connecting portion 4044 is provided with a thread, which matches the thread of the screw 4045c. When in use, the screw 4045c is first loosened, and then the hanging rod 4041 is adjusted to a suitable height, and then the screw 4045c is tightened. Under the action of the screw 4045c and the third through hole 4044a, the hanging rod 4041 can be fixed at this position, and the height adjustment of the hanging rod 4041 in the Y direction can be completed.

[0110] Embodiment five:

[0111] like Figure 28-31 As shown, the only difference between the fifth embodiment and the second embodiment is that the hanger can move on the guide rail.

[0112] Specifically, the hanger 4050 is rotatably connected to the main body 100. The hanger 4050 includes a hanger rod 4051, a rotating part 4052, a first fixing part 4053, a second fixing part 4054, a sliding block 4055 and a guide rail 4057. The first fixing part 4053 is a U-shaped structure, which includes a first fixed plate and two side plates 40531 vertically connected to the first fixed plate and spaced from each other. One end of the hanger rod 4051 is connected to the rotating part 4052, the rotating part 4052 is rotatably connected to the first fixing part 4053 through a first rotating shaft, the first fixing plate is rotatably connected to the second fixing part 4054 through a second rotating shaft, and the second fixing part 4054 is fixedly connected to the sliding block 4055 on the side facing away from the hanger rod 4051. Among them, the first rotating axis is arranged parallel to the X direction, so that the rotating part 4052 can rotate 0-90° around the first rotating axis relative to the first fixing part 4053 in the YZ plane; the second rotating axis is arranged parallel to the Y direction, so that the first fixing part 4053 can rotate 0-180° around the second rotating axis relative to the second fixing part 4024 in the XZ plane; through the above arrangement, the hanging rod 4051 can rotate in the XY plane, the YZ plane or the XZ plane, and can also rotate in the XY plane, the XZ plane and the YZ plane at the same time, so the operator can adjust the position of the hanging rod 4051 according to actual needs.

[0113] The hanging rod 4051 has a working state and a natural state. When the hanging rod 4051 is in the working state (the hanger 4050 is also in the working state at this time), the free end of the hanging rod 4051 is located at a position away from the main body 100, that is, the working position; when the hanging rod 4051 is in the natural state (the hanger 4050 is also in the natural state at this time), the free end of the hanging rod 4051 is located at a position close to the main body 100, that is, the natural position. When the hanger 4050 is in the working state, the angle between the hanging rod 4051 on the hanger 4050 and the Y direction is an acute angle or a right angle. It can be seen that in the working state, when medical equipment such as an ultrasound probe or medical devices such as a catheter are placed on the hanger 4050, it can be prevented that the medical devices slip off the hanger 4050 and fall to the ground due to gravity.

[0114] The second fixing member 4054 is provided with at least one fixing hole, and the second fixing member 4054 can be fixedly connected to the sliding block 4055 through the fixing hole by means of screw connection, pin connection, etc. Of course, the second fixing member 4054 can also be fixedly connected to the sliding block 4055 by means of snap-fitting, etc., which will not be repeated here. The sliding block 4055 is provided with a groove 4055a on the side facing the main body 100, and the guide rail 4057 is provided with a protrusion 4057b on the side corresponding to the groove 4055a. The groove 4055a and the protrusion 4057b can achieve concave-convex matching, so that the sliding block 4055 can slide on the guide rail 4057. The guide rail 4057 is also provided with a through hole 4057a, which is used to fix the guide rail 4057 on one side of the main body 100.

[0115] In addition, the sliding block 4055 is provided with a plurality of through holes 4055b, each of which is provided with a thread, and the thread of at least one through hole 4055b matches the thread of the screw 4056, and the screw 4056 passes through the through hole 4055b and can abut against the guide rail 4057. Through the above arrangement, after the sliding block 4055 is adjusted to a suitable position, the screw 4056 is tightened so that the screw 4056 abuts against the guide rail 4057, so that the sliding block 4055 is positioned at the position; when the position of the sliding block 4055 needs to be adjusted, the screw 4056 is loosened so that the screw 4056 is away from the guide rail 4057, so that the sliding block 4055 can be moved to adjust its position in the Y direction.

[0116] Embodiment six:

[0117] like Figure 32-37 As shown, the difference between the sixth embodiment and the fifth embodiment is only in the guide rail and the sliding block.

[0118] Specifically, the hanger 4060 is rotatably connected to the main body 100. The hanger 4060 includes a hanger rod 4061, a rotating part 4062, a first fixing member 4063, a second fixing member 4064, a sliding block 4065, two spring members 4068 and a guide rail 4067, and the sliding block 4065 can move on the guide rail 4067. The first fixing member 4063 is a U-shaped structure, which includes a first fixing plate 40631 and two side plates 40632 vertically connected to the first fixing plate 40631 and spaced from each other. The second fixing member 4064 and the sliding block 4065 are fixed together by screws, one end of the hanging rod 4061 is connected to the rotating part 4062, the rotating part 4062 is rotatably connected to the first fixing member 4063 through the first rotating shaft, the first fixed plate 40631 is rotatably connected to the second fixing member 4064 through the second rotating shaft, and the side of the second fixing member 4064 facing away from the hanging rod 4061 is connected to the sliding block 4065 through the spring member 4068. Among them, the first rotating axis is arranged parallel to the X direction, so that the rotating part 4062 can rotate 0-90° around the first rotating axis relative to the first fixing part 4063 in the YZ plane; the second rotating axis is arranged parallel to the Y direction, so that the first fixing part 4063 can rotate 0-180° around the second rotating axis relative to the second fixing part 4024 in the XZ plane; through the above arrangement, the hanging rod 4061 can rotate in the XY plane, the YZ plane or the XZ plane, and can also rotate in the XY plane, the XZ plane and the YZ plane at the same time, so the operator can adjust the position of the hanging rod 4061 according to actual needs.

[0119] The hanging rod 4061 has a working state and a natural state. When the hanging rod 4061 is in the working state (the hanger 4060 is also in the working state at this time), the free end of the hanging rod 4061 is located at a position away from the main body 100, that is, the working position; when the hanging rod 4061 is in the natural state (the hanger 4060 is also in the natural state at this time), the free end of the hanging rod 4061 is located at a position close to the main body 100, that is, the natural position. When the hanger 4060 is in the working state, the angle between the hanging rod 4061 on the hanger 4060 and the Y direction is an acute angle or a right angle. It can be seen that in the working state, when medical equipment such as an ultrasound probe or medical devices such as a catheter are placed on the hanger 4060, it can be prevented that the medical devices slip off the hanger 4060 and fall to the ground due to gravity.

[0120] The projection of the guide rail 4067 on the XZ plane is L-shaped, one side of the L-shape is provided with a through hole 4067a and a protrusion 4067b, and the other side of the L-shape is a rack 4066. The through hole 4067a is used to fix the guide rail 4067 on one side of the main body 100. The spring member 4068 includes a rod portion 4068a and a spring 4068b. A meshing portion 4064a and two through holes 4064c are provided on the side of the second fixing member 4064 facing the rack 4066, wherein the meshing portion 4064a is adapted to the shape of the rack 4066 so that the meshing portion 4064a can be engaged with the rack 4066; the inner diameter of the through hole 4064c is larger than the outer diameter of the rod portion 4068a, so one end of the rod portion 4068a can pass through the through hole 4064c; two through holes 4065c are provided on the side of the sliding block 4065 away from the rack 4066, and the through hole 4065c is fixedly connected to the other end of the rod portion 4068a, and the spring 4068b is sleeved on the rod portion 4068a and the two ends of the spring 4068b are respectively in contact with the sliding block 4065 and the second fixing member 4064.

[0121] When the height of the hanging rod 4061 in the Y direction needs to be adjusted, the spring 4068b can be compressed by applying a force in the X direction to the second fixing member 4064, so that the meshing portion 4064a is separated from the rack 4066, and the sliding block 4065 can move along the guide rail 4067 in the Y direction; after the sliding block 4065 moves to a suitable position, the force is canceled, and the second fixing member moves in the direction opposite to the X direction under the action of the spring 4068b until the meshing portion 4064a abuts against the rack 4066, and the sliding block 4065 is restricted from moving and can be fixed in this position. The second fixing member 4064 also has a groove 4064b, and the cooperation between it and the rotating portion 4062 is not repeated here.

[0122] Embodiment seven:

[0123] like Figure 38-39 As shown, the only difference between the seventh embodiment and the fifth embodiment is the guide rail and the sliding block.

[0124] Specifically, the bracket 4070 is rotatably connected to the main body 100. The bracket 4070 includes a hanging rod 4071, a rotating part 4072, a first fixing member 4073, a second fixing member 4074, a sliding block 4075, a motor 4076, a guide rail 4077 and a screw rod 4078, and the sliding block 4075 can move on the guide rail 4077.

[0125] The first fixing member 4073 is a U-shaped structure, which includes a first fixing plate and two side plates vertically connected to the first fixing plate and spaced apart from each other. One end of the hanging rod 4071 is connected to the rotating portion 4072, and the rotating portion 4072 is rotatably connected to the first fixing member 4073 via a first rotating shaft. The first fixing plate is rotatably connected to the second fixing member 4074 via a second rotating shaft, and the second fixing member 4074 is fixedly connected to the sliding block 4075. Among them, the first rotating axis is arranged parallel to the X direction, so that the rotating part 4072 can rotate 0-90° around the first rotating axis relative to the first fixing part 4073 in the YZ plane; the second rotating axis is arranged parallel to the Y direction, so that the first fixing part 4073 can rotate 0-180° around the second rotating axis relative to the second fixing part 4024 in the XZ plane; through the above arrangement, the hanging rod 4071 can rotate in the XY plane, the YZ plane or the XZ plane, and can also rotate in the XY plane, the XZ plane and the YZ plane at the same time, so the operator can adjust the position of the hanging rod 4071 according to actual needs.

[0126] The hanging rod 4071 has a working state and a natural state. When the hanging rod 4071 is in the working state (the hanger 4070 is also in the working state at this time), the free end of the hanging rod 4071 is located at a position away from the main body 100, that is, the working position; when the hanging rod 4071 is in the natural state (the hanger 4070 is also in the natural state at this time), the free end of the hanging rod 4071 is located at a position close to the main body 100, that is, the natural position. When the hanger 4070 is in the working state, the angle between the hanging rod 4071 on the hanger 4070 and the Y direction is an acute angle or a right angle. It can be seen that in the working state, when medical equipment such as an ultrasound probe or medical devices such as a catheter are placed on the hanger 4070, it can be prevented that the medical devices slip from the hanger 4070 and fall to the ground due to gravity.

[0127] Furthermore, one end of the sliding block 4075 is sleeved on the screw rod 4078, and the other end of the sliding block 4075 is movably connected to the guide rail 4077. The motor 4076 is connected to one end of the screw rod 4078. The motor 4076 can drive the screw rod 4078 to rotate. During the rotation of the screw rod 4078, the sliding block 4075 can move in the Y direction, thereby driving the hanging rod 4071 to move in the Y direction.

[0128] When it is necessary to adjust the height of the hanging rod 4071 in the Y direction, by adjusting the rotation direction of the motor 4076, the screw rod 4078 can drive the sliding block 4075 to move along the guide rail 4067 in the Y direction or in the direction opposite to the Y direction; after the sliding block 4075 moves to the appropriate position, the motor 4076 is turned off, and the sliding block 4075 is restricted from moving, so it can be fixed in this position.

[0129] Embodiment eight:

[0130] like Fig.40 As shown, the present invention further provides a radiation protection system 1, comprising at least two radiation protection devices 10 according to one of the above embodiments, and two adjacent radiation protection devices 10 are detachably connected.

[0131] During use, if the radiation source is too large or there are multiple radiation sources and the multiple radiation sources are arranged in parallel, so that a single radiation protection device 10 is not sufficient to block all rays, at least two radiation protection devices 10 can be arranged in parallel accordingly; if the radiation source is too large and irregular or there are multiple radiation sources and the multiple radiation sources are dispersed around the operator, so that a single radiation protection device 10 is not sufficient to block all rays, at least two radiation protection devices 10 can be arranged around the operator accordingly (for example, there is an angle between two adjacent radiation protection devices 10); the above-mentioned settings can expand the scope of radiation protection, thereby further improving the effect of radiation protection.

[0132] like Figure 1 and Fig.40 As shown, in some embodiments, three radiation protection devices 10 are arranged in parallel. Compared with a single radiation protection device 10, the protection range of the radiation protection system 1 is greatly increased. In addition, two adjacent radiation protection devices 10 are detachably connected, so that it is convenient for the operator to disassemble the radiation protection device 10 according to actual needs (for example, after use, the adjacent radiation protection devices 10 can be separated for easy placement and storage), which is conducive to improving the convenience of use of the radiation protection system 1. Specifically, the connection between two adjacent radiation protection devices 10 can be threaded connection, welding and crimping, etc. In this embodiment, threaded connection is preferred for easy disassembly and assembly. In some embodiments, the operator can also select the number and height of the radiation protection device 10 according to actual needs to meet the needs of different usage scenarios.
