Description

Technical Field

[0001] This utility model belongs to the field of medical protective equipment, specifically relating to a comprehensive radiation protection device. Background Technology

[0002] Interventional surgeries generate significant amounts of radiation over extended periods, which can harm the health of medical personnel. Therefore, radiation protection devices are crucial for medical staff, effectively protecting doctors from radiation.

[0003] Instrument protection is generally achieved through radiation protection equipment, such as lead aprons, lead aprons, and lead goggles. Lead aprons are currently the most commonly used protective equipment, but their weight can restrict the movement of medical staff to some extent, affecting the flexibility and precision of surgical procedures. In addition, interventional surgeries require doctors to stand for several hours continuously, and wearing heavy lead aprons for extended periods while performing high-intensity work can also cause harm to the doctors' health.

[0004] To address the aforementioned issues, some hospitals and other medical institutions have designed relevant protective devices, but these all have certain shortcomings. For example, publication number CN114582540 A discloses a fully adjustable radiation protection device, specifically a main body with casters installed at the corner of its bottom edge, locking blocks installed at the side edges, openings on both sides of the top, a carrier plate slidably mounted on the bottom, and a flipping mechanism installed on the side; the flipping mechanism has a baffle mounted on the top of the carrier plate via a pivot; and an upper protective component installed at the bottom of the main body, with a push plate mounted on the edge of the carrier plate. This device can be adjusted according to different equipment heights and is equipped with casters for easy movement, but it can only protect the equipment itself and cannot be used for the protection of medical personnel performing interventional surgeries.

[0015] The two ends of the sliding part of the hand radiation shield are slidably installed in the first guide rail hole.

[0016] Preferably, each of the side radiation shielding plates also covers the first guide rail, and the two front radiation shielding plates are respectively installed on the front side of the first guide rail.

[0017] Preferably, the sliding part of the hand radiation shield and the shielding part of the hand radiation shield are integrally formed, and a bending part is formed between them.

[0033] Preferably, the bottom end of the radiation-proof curtain is higher than the bottom end of the caster wheel seat.

[0034] Compared with the prior art, the beneficial effects of this utility model are:

[0035] 1. This utility model includes a support frame with motor-driven casters for surgical personnel to enter. The side of the support frame facing the surgical personnel is designated as the front of the support frame, the side facing away from the support frame is designated as the rear of the support frame, the sides of the two arms are designated as the sides of the support frame, and the side above the head is designated as the top of the support frame. The direction from the top edge to the bottom of the support frame is designated as the height direction. It includes side radiation shielding plates installed and covering the two sides of the support frame, a top radiation shielding plate installed and covering the top edge of the support frame, and a rear radiation shielding door movably installed and covering the rear of the support frame. Two front radiation shielding plates are installed and covering the front of the support frame, forming a first gap in the height direction. A hand is movably positioned within this first gap along the height direction. The system includes a side radiation shield, with the hand radiation shield overlapping the two front radiation shields in the vertical direction. The hand radiation shield has hand holes for surgical personnel to insert their hands into the surgical area within the support frame. A radiation shield curtain is installed at the bottom of the support frame in the vertical direction, leaving a second gap with the ground. The purpose of this system is to utilize the side radiation shield, top radiation shield, rear radiation shield, two front radiation shields, hand radiation shield, and radiation shield curtain installed on the support frame to form a relatively sealed protective device. During operation, medical personnel insert their gloved hands into the surgical area through the hand holes. Compared to traditional protective devices, this system uses transparent radiation shielding materials that meet radiation protection performance requirements and offer better protection, providing comprehensive and effective protection for personnel.

[0036] 2. Because the support frame of this utility model has two first guide rails at the front of the support frame, the two first guide rails are respectively arranged along the two sides of the front of the support frame, each first guide rail extends along the height direction, and each first guide rail has a first guide rail hole corresponding to the first guide rail. The hand radiation shield has a hand radiation shield sliding part and a hand radiation shield blocking part, and the hand radiation shield sliding part and the hand radiation shield blocking part are fixed together in the height direction; the upper surface of the hand radiation shield sliding part overlaps with the bottom of the front radiation shield at the upper end along the height direction, and the lower surface of the hand radiation shield blocking part overlaps with the top of the front radiation shield at the lower section along the height direction; the two ends of the hand radiation shield sliding part are slidably installed in the first guide rail holes, the purpose of which is that when the hand radiation shield sliding part is slidable, the hand radiation shield blocking part is always blocked by the front radiation shield at the lower end, and the hand radiation shield sliding part is always blocked by the front radiation shield at the upper end, thereby avoiding medical personnel from being in the radiation range, so as to play a good protective role.

[0037] 3. Because the sliding part of the hand radiation shield and the shielding part of the hand radiation shield are integrally formed in this utility model, and a bending part is formed between them, especially forming a Z-shape, the purpose is that the structure meets the needs of ergonomics and interventional surgery. When the user observes the surrounding environment through the protruding sliding part of the hand radiation shield, the head is not restricted and the field of vision is better.

[0038] 4. Because the support frame in this utility model has limiting racks installed on both sides at the front, and the two limiting racks extend along the height direction, locking members are fixedly connected to both sides of the hand radiation shielding part, and each locking member is rotatably mounted with a gear. Each gear meshes with the limiting rack, and the locking member is also provided with a locking mechanism for locking the locking member when it moves to a designated position on the support frame. The purpose is to allow the gear to move on the limiting rack, thereby enabling the hand radiation shielding part to move on the support frame, and to use the locking mechanism to limit the locking member when it moves to a designated position on the support frame, thereby limiting the distance the hand radiation shielding part moves on the support frame. This allows for height adjustment according to the user's height, ensuring that the user's hand can move freely after passing through the radiation shielding part, without affecting the overall protection.

[0039] 5. Because the side radiation shielding plate, top radiation shielding plate, rear radiation shielding door, front radiation shielding plate and hand radiation shielding plate in this utility model are all transparent plates, and all are transparent acrylic plates, the purpose is to facilitate personnel to observe the surrounding situation through the transparent acrylic plates inside, and the overall visibility is better so as to carry out good surgical operations.

[0058] Transparent acrylic side radiation shielding plates 4 are installed and cover the two support frame sides C respectively. Specifically, the side radiation shielding plates 4 are installed and cover the two support frame sides C by screws.

[0059] A transparent acrylic top edge radiation shielding plate 5 is installed and covers the top edges D of the two supporting frames. Specifically, the top edge radiation shielding plate 5 is installed and covers the top edges D of the supporting frames using screws.

[0060] Transparent acrylic rear radiation shielding door 6 (e.g.) Figure 5 As shown), the rear radiation shielding door 6 is movably installed and covers the back of the support frame B. Specifically, the rear radiation shielding door 6 is movably installed and covers the back of the support frame B by screws, and the rear radiation shielding door 6 is opened and closed by a transmission mechanism (e.g., a cylinder), which is controlled by a control panel.

[0061] Two transparent acrylic front radiation shielding panels 7 are installed and cover the front A of the support frame. Specifically, the two front radiation shielding panels 7 are installed and cover the front A of the support frame by screws.

[0062] The two front radiation shielding plates 7 form a first gap in the height direction H. A transparent acrylic hand radiation shielding plate 8 is movably installed within the first gap along the height direction H, and the hand radiation shielding plate 8 overlaps with the two front radiation shielding plates 7 in the height direction H (e.g., Figure 4 , 7 As shown), the hand radiation shielding plate 8 has a hand hole 9, which is used for the surgeon's hand to reach into the surgical area within the support frame 3.

[0063] The radiation shielding curtain 10 is installed at the bottom of the support frame 3 along the height direction H, with a second gap between it and the ground.

[0064] The support frame 3 has two first guide rails 11 at its front A side. The two first guide rails 11 are respectively arranged on both sides of the front A side of the support frame. Each first guide rail 11 extends along the height direction H, and each first guide rail 11 has a first guide rail hole 12 corresponding to the first guide rail 11.

[0065] The hand radiation shield 8 has a hand radiation shield sliding part 81 and a hand radiation shield blocking part 82, and the hand radiation shield sliding part 81 and the hand radiation shield blocking part 82 are fixed together in the height direction H (the hand radiation shield sliding part 81 and the hand radiation shield blocking part 82 are integrally formed, and a bend is also formed between them, such as...). Figure 15 (as shown); and the upper surface of the hand radiation shield sliding part 81 overlaps with the bottom of the front radiation shield 7 at the upper end along the height direction H, the lower surface of the hand radiation shield shield 82 overlaps with the top of the front radiation shield 7 at the lower section along the height direction H, and the two ends of the hand radiation shield sliding part 81 are slidably installed in the first guide rail hole 12.

[0066] Each side radiation shield 4 also covers the first guide rail 12, and the two front radiation shields 7 are respectively installed on the front side of the first guide rail 11.

[0067] An end fixing member 121 is provided at the lower end of the first guide rail hole 12 to support and limit the sliding part 81 of the hand radiation shield.

[0068] Limiting racks 13 are installed on both sides of the front A of the support frame (limiting racks 13 are installed on both sides of the front A of the support frame by bolts), and the two limiting racks 13 extend along the height direction H. Locking members 14 are fixedly connected to both sides of the hand radiation shielding part 82, and each locking member 14 is rotatably mounted with a gear 15. Each gear 15 meshes with the limiting rack 13. The locking member 14 is also provided with a locking mechanism for locking the locking member when it moves to a designated position on the support frame 3.

[0069] In addition, such as Figure 9-12 As shown, the locking mechanism includes a lifting assembly, a locking nut 16, and a fastening bolt 17. The lifting assembly is fixed to the sliding part 81 of the hand radiation shield and has a cavity inside. The gear 15 is rotatably mounted on the lifting assembly and is located inside the cavity. The lifting assembly is provided with a locking hole 20. The fastening bolt 17 passes through the locking hole 20 and is tightened to fasten the locking nut 16. The fastening bolt 17 passes through the locking hole 20 and abuts against the support frame 3. The purpose is to lock the gear rack after the sliding shield of the hand radiation shield is moved to the appropriate position, so as to prevent the hand radiation shield from moving during the operation and affecting the protective effect.

[0070] The lifting assembly is also equipped with a second guide rail 18, which is located in the cavity and is close to the gear 15. The limiting rack 13 is provided with a groove 19 extending along the height direction H, and the cavity is open along the side wall of the front side A of the support frame. The second guide rail 18 slides in the groove 19, and the direction in which the second guide rail 18 slides in the groove 19 is consistent with the direction in which the gear 15 travels on the limiting rack 13. Furthermore, the support frame 3 is provided with damping, and the fastening bolt 17 passes through the locking hole 20 and abuts against the damping on the support frame 3 to ensure tight contact between the connecting parts and prevent loosening.

[0071] A universal wheel seat 31 is installed on the bottom edge of the support frame 3. A motor 1 is installed on the universal wheel seat 31. A universal wheel 2 is installed at the bottom of the universal wheel seat 31. The free end of the motor 1 is coupled to the shaft where the universal wheel 2 is located.

[0072] The bottom of the radiation-proof curtain 10 is higher than the bottom of the universal wheel seat 31.

[0073] This invention can also be equipped with an automatic following system, including a displacement sensor 22 and a control panel. The displacement sensor 22 is located at the lower part of the support frame 3 and is used to detect the distance l between the person and the lower end of the support frame. When the person moves towards the edge of the support frame 3, the distance l between them decreases, and the motor 1 drives the casters 2 to adjust the position of the protective device in the direction of the person's movement. The control panel controls the automatic steering and movement of the casters 2, thereby realizing that the protective device automatically follows the person's footsteps and adjusts its position. In addition, the displacement sensor 22 is an ultrasonic sensor, which is suitable for close-range target detection and can be used in radiation environments. Figure 13 As shown, displacement sensor 22 is installed on the lower side of support frame 3. One displacement sensor 22 (i.e., the first displacement sensor and the second displacement sensor) is placed on the bottom front side and the bottom side of support frame 3, respectively. The sensing end of the first sensor faces the front of the person, and the sensing end of the second displacement sensor faces the side of the person, so as to detect the front and back and left and right movement distance of the person relative to this device. Each sensor includes two transmitting ports and a receiver, and has a built-in sensor control panel and power supply. The sensor control panel is electrically connected to the control panel.

[0074] The omnidirectional wheel base is equipped with four motors, namely the first motor, the second motor, the third motor, and the fourth motor (e.g., ...). Figure 1 , 2 As shown in Figure 3), each motor 1 is driven independently, that is, each motor 1 is electrically connected to the control panel, and the output terminal of each displacement sensor is electrically connected to the control panel.

[0075] The device is equipped with a walkie-talkie 23 (such as...). Figure 7 , 8 The walkie-talkie 23 is used to communicate with the outside world when a person enters the device and closes the rear radiation shielding door 6.

[0076] The device is equipped with end connectors 21 for fixing the ends of the various components of the support frame 3.

[0077] The specific steps for using this utility model are as follows:

[0078] 1) Move this device to the side of the operating table, so that the lower part of the device can be close to the edge of the operating table;

[0079] 2) Place the surgical guidewire and catheter opposite the device or at the corresponding position on the operating table, put on protective gloves, stand behind the protective device, and enter the device through the rear radiation shielding door 6.

[0080] 3) Facing the hand radiation shield 8, put both hands through the hand holes 9 and pull or lower the hand radiation shield 8 to a suitable position according to your own use, and fix it relatively by locking the locking piece 14; when the shoulder is close to the hand radiation shield 8, the user's head still has a certain amount of space to move away from the upper front radiation shield 7, and can use this space to obtain a better field of vision.

[0081] 4) If necessary, the device can be moved to the side, and the control system will control the casters 3 to follow the personnel, thus enabling the device to move accordingly;

[0082] 5) After the surgery, reverse the procedure described above and leave the protective device;

[0083] 6) After the rear radiation shielding door 6 is closed, push the protective device to a suitable position for storage.

[0084] Compared to traditional protective devices, this invention utilizes a side radiation shielding plate 4, a top radiation shielding plate 5, a rear radiation shielding door 6, two front radiation shielding plates 7, a hand radiation shielding plate 8, and a radiation shielding curtain 10 mounted on a supporting frame 3 to form a relatively sealed protective device. (It should be noted that the relative sealing described in this invention does not consider the second gap, i.e., the radiation shielding curtain not being fully supported by the ground, and the hand hole, i.e., the gap between the hand hole and the hand after the surgeon has inserted their hand). Furthermore, this invention uses radiation shielding materials with high lead equivalent and better protective performance to protect the user's entire body, thus providing a superior protective effect. Compared to traditional devices that require wearing lead protective clothing, this invention significantly reduces the user's physical burden, making the usage process easier and more comfortable.

[0085] The radiation shielding panels in this article can be made of transparent radiation shielding materials such as radiation shielding acrylic sheets or lead glass. Preferably, the radiation shielding acrylic sheets are used. The supporting frame 3 can be made of materials such as aluminum alloy profiles or carbon fiber. This does not limit the scope of this utility model.

[0086] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
