Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a quick-disassembly and assembly anti-overflow magnetic resonance compatible partition assembly and a magnetic resonance treatment device. Background Art

[0002] In modern medical research and clinical practice, magnetic resonance imaging (MRI) is widely used in various diagnostic and therapeutic methods due to its high resolution and non-invasive characteristics. With the continuous development of magnetic resonance technology, more and more magnetic resonance-guided treatment devices have been developed, such as magnetic resonance-guided surgical robots and magnetic resonance-guided radiotherapy systems. These devices need to be in close contact with patients during use and often involve the use of liquids, such as infusion or injection of coupling fluid. However, in a magnetic resonance environment, any spillage of liquid may damage sensitive magnetic resonance equipment and even affect the quality of magnetic resonance imaging, posing serious safety risks.

[0003] Existing auxiliary devices for magnetic resonance equipment have many deficiencies in waterproof design. Traditional water-blocking devices are often cumbersome to install and inconvenient to disassemble and assemble, making it difficult to meet the needs of rapid response and efficient operation. At the same time, these devices are not compatible enough in the magnetic resonance environment and may contain magnetic materials, which may affect magnetic resonance imaging and even cause equipment failure. Therefore, there is an urgent need to design a partition that can be quickly disassembled and assembled, effectively prevents water overflow, and is compatible with the magnetic resonance environment, so as to ensure the safety of the equipment and convenient operation during magnetic resonance treatment.

[0004] In addition, as medical equipment develops towards intelligence and modularization, highly versatile water-blocking devices have broad application prospects in different types of magnetic resonance equipment. Whether it is a surgical robot guided by magnetic resonance or other magnetic resonance-assisted treatment equipment, an efficient and reliable anti-overflow solution is required. Therefore, the development of a partition that can be quickly disassembled, anti-overflow, and compatible with magnetic resonance can not only improve the safety and reliability of magnetic resonance treatment equipment, but also improve the efficiency of medical operations and meet the diverse needs in the modern medical environment.

[0005] In summary, the development of a quick-disassembly and anti-overflow magnetic resonance compatible partition is of great significance for ensuring the safe operation of various magnetic resonance treatment equipment and improving the quality of medical services. Summary of the invention

[0006] The purpose of the present invention is to provide a quick-disassembly and anti-overflow magnetic resonance compatible partition assembly and magnetic resonance treatment equipment to solve the waterproof and compatibility problems in the prior art. The partition assembly can be widely used in different types of magnetic resonance treatment equipment to promote the further development and innovation of medical equipment technology.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A quick-disassembly and assembly anti-overflow magnetic resonance compatible baffle assembly, comprising:

[0009] The partition unit comprises a main body, wherein the main body is provided with two receiving grooves and guide holes arranged around the receiving grooves, the guide holes penetrate the main body in the thickness direction, and there is a certain distance between the two receiving grooves;

[0012] Preferably, the partition unit further comprises a pressure strip, and the pressure strip is arranged in the receiving groove to divide the receiving groove into a receiving area and a buffer area.

[0013] Preferably, the area of ​​the accommodating zone is larger than the area of ​​the buffer zone.

[0014] Preferably, the guide holes include side guide holes and middle guide holes, the middle guide hole is arranged directly opposite to the middle between the two accommodating grooves, and the side guide holes deviate from the middle.

[0015] Preferably, the area of ​​the middle flow guide hole is larger than the area of ​​the side flow guide holes.

[0016] Preferably, the fixing unit comprises a fixing seat connected to the main body of the partition and a buckle connected to the fixing seat, and the buckle is adapted to fit into a mounting hole on the treatment device.

[0017] Preferably, the chest pad and the side pads each include an outer cover and an inner core arranged inside the outer cover, and the inner core is made of soft material.

[0018] Preferably, the cushion unit further comprises two anti-overflow cushions located between the two side cushions.

[0019] Preferably, the cushion unit and the partition unit are sealed and connected so that liquid cannot pass through.

[0020] The cushion unit and the partition can be directly bonded by glue to achieve a sealed connection. However, this method cannot replace the cushion unit. In another preferred embodiment, the cushion unit and the partition unit are connected by a pressure plate unit, and the pressure plate unit and the partition unit are detachably connected.

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0046] Example 1

[0047] This embodiment provides a quick disassembly and assembly anti-overflow magnetic resonance compatible partition assembly, see Figure 1-Figure 5 , comprising a cushion unit 100, a partition unit 200, and a fixing unit 300.

[0048] The pad unit 100 includes a chest pad 101, two left and right side pads 102, and two front and rear anti-overflow pads 103, which are interconnected into a whole. The side pads 102 are thicker than the anti-overflow pads 103, and the chest pad 101 is the thinnest. The inner core of various pads is a soft material. When the surface is subjected to gravity, it will deform accordingly; when the gravity is removed, the surface will return to its original shape; in addition, it has anti-mold properties in a humid environment for a long time. The outside of the pad is a cover, which is soft, waterproof, and easy to clean; it needs to have relevant properties that meet biocompatibility, such as cytotoxicity, skin irritation, sensitization, etc.; the surface also needs to have flame retardant properties to meet the requirements of relevant flame retardant laws and regulations; at the same time, it also needs to have anti-mold and antibacterial related functions to avoid unacceptable risks during long-term storage.

[0049] The chest pad 101 is the place where the human body contacts the inner side of the human chest when the human body lies prone on the treatment device 400. When the human body lies prone on the chest pad 101, the chest pad 101 will be deformed accordingly due to the effect of gravity. Because of its soft texture, it can make the human body 700 feel the maximum degree of comfort and avoid various discomforts caused by lying prone for a long time. The side pads 102 and the anti-overflow pads 103 prevent the overflow of water in the sound-permeable membrane 500 under different circumstances: such as the movement of the human body, the fluctuation of water flow when water is injected into the sound-permeable membrane 500, and the instability of the treatment device when moving.

[0050] The connection between the cushion unit 100 and the partition unit 200 can be glued, welded or other methods to ensure the sealing of the connection to prevent water from overflowing from the connection.

[0051] The partition unit 200 includes a main body, including a receiving groove 201, a guide hole 202, and a pressure strip 203. The partition unit 200 is made of a non-magnetic material to ensure that the imaging is not affected when the magnetic resonance image is working.

[0052] The receiving groove 201 is a hollow structure. The breast of the human body 700 passes through the receiving groove 201 and is finally placed in the sound-transmitting membrane 500, which is convenient for treating breast-related diseases. The diversion hole 202: When too much water is injected into the sound-transmitting membrane 500 and overflows, or when the water overflows due to the movement of the human body 700 and the movement of the treatment device 400, the water can be accurately diverted to the storage and drainage mechanism on the treatment device 400 through this diversion hole, avoiding excessive water having no place to be discharged during long-term treatment, resulting in damage to the magnetic resonance equipment. The pressure strip 203 is used to press down the extension of the sound-transmitting membrane 500, avoiding local movement of the sound-transmitting membrane 500 during treatment, causing water in the sound-transmitting membrane 500 to overflow, resulting in unacceptable risks related to the treatment. At the same time, the edge of the receiving groove 201 also acts as a part of the pressure strip.

[0053] The pressure strip 203 is arranged in the accommodating groove 201, and its upper surface is flush with the upper surface of the edge of the accommodating groove 201. The pressure strip 203 divides the accommodating groove 201 into two parts. One part is the accommodating area for accommodating the human breast, which has a larger area, and the other part is the buffer zone, which has a smaller area. This is mainly to ensure that under the action of the pressure strip 203, the sound-transmitting membrane is squeezed and deformed, and a part of it will be squeezed out. This part is squeezed and located in the buffer zone to ensure the stability of the entire partition assembly.

[0054] The fixing unit 300 includes a fixing seat 301 and a buckle 302. The buckle 302 is used for rapid connection and disassembly with the treatment device 400. The buckle 302 only needs to be aligned with the relevant hole position on the treatment device 400, and then a light press can be used to complete the installation of the rapid disassembly and assembly of the anti-overflow magnetic resonance compatible baffle assembly, and a light pull can be used to complete the disassembly and assembly of the rapid disassembly and assembly of the anti-overflow magnetic resonance compatible baffle assembly. This avoids the cumbersome disassembly and assembly of screws when fixing with screws, greatly increasing the efficiency of use during treatment. At the same time, the buckle 302 can also be a non-magnetic material, which realizes relevant compatibility performance for the magnetic resonance equipment and avoids the risk of the outlet line affecting the image imaging.

[0055] The fixing seat 301 is used to connect the partition unit 200 and the buckle 302, playing a connecting role. The connection method can be screw fixing, welding, hot melting, or even the main body of the partition unit and the fixing seat 301 can be integrated into one. The fixing seat is a non-magnetic hard material to avoid the risk of the buckle 302 loosening or shifting due to the material being too soft. At the same time, it also meets the relevant magnetic resonance performance and avoids the relevant imaging risks.

[0056] See also Figure 6This embodiment provides a magnetic resonance treatment device, including a device body 400, a sound-transmitting membrane 500 and a sound-transmitting soft membrane 600, wherein the quick disassembly and assembly anti-overflow magnetic resonance compatible baffle assembly is installed on the device body 400 and is located above the sound-transmitting soft membrane 600. The sound-transmitting membrane is used to contain degassed water, and the energy of the treatment device body 400 can penetrate the sound-transmitting membrane 500 and focus on the lesion. The material can be PET, TPU, PVC and other materials.

[0057] Example 2

[0058] The difference between this embodiment and embodiment 1 is that the connection structure between the cushion unit and the partition unit is different. In this embodiment, a pressure plate unit is added, see Figure 7 The main function of the pressure plate unit is to fix the cushion unit 100 to prevent water leakage at the contact surface. Figure 8 , including a pressing plate, on the action surface of the pressing plate (the surface pressing the cushion unit 100), a countersunk hole 901, a sealing groove 902 and a guide block 903 are provided, and a sealing ring 1000 is provided in the sealing groove 902. A guide groove 105 is provided at a position corresponding to the guide block 903 on the cushion unit, and a through hole 106 is provided at a position corresponding to the countersunk hole 901. A non-magnetic nut 206 is provided at a position corresponding to the countersunk hole 901 and the through hole 106 of the partition unit 200.

[0059] In this embodiment, there are 8 guide blocks 903 in total, and after the guide blocks 903 pass through the cushion guide groove 105, they are inserted into the partition guide groove 205. In this way, the cushion unit 100 can be installed at the expected position, avoiding unexpected movement of the cushion unit, and also ensuring that when the screws are used to lock the whole later, the screws can pass through the through holes 106 smoothly and quickly.

[0060] The countersunk hole 901 is used to place a screw, pass through the through hole 106, and finally be locked to the non-magnetic nut 206.

[0061] The sealing groove 902 is used to place the sealing ring 1000. Since the sealing ring is made of elastic material, it is pre-compressed to fill the microscopic gap of the contact surface during installation to form an initial sealing barrier. At this time, the cushion unit 100 is compressed and cannot move at will.

[0062] The non-magnetic nut 206 can be installed to the partition unit 200 by a hot pressing process, and the partition unit 200 can be processed by mechanical processing, 3D printing, silicone molding and other processes.

[0063] The non-magnetic nut 206 can also be integrally molded with the partition unit 200 by encapsulation and injection molding.

[0064] The partition unit 200 is made of plastic, such as ABS, POM, PC+ABS, acrylic, etc.

[0065] The sealing ring 1000 is a standard part and is made of elastic material, such as silicone, nitrile rubber, fluororubber, EPDM rubber, etc.

[0066] The pressing plate 900 is made of plastic material, which may be PP, PA, acrylic, etc., and may be processed by injection molding, machining, etc.

[0067] The pad unit 100 is made of a flexible material, and the pad guide grooves 105 and the through holes 106 on the surface thereof may be completed using a laser processing process.

[0068] Installation process:

[0069] 1. Place the partition unit 200 on a horizontal surface with the fixing unit 300 facing downward;

[0070] 2. Place the cushion unit 100 on the partition unit 200, and make sure that the cushion guide groove 105 is initially aligned with the partition guide groove 205;

[0071] 3. Install the sealing ring 1000 into the sealing groove 902 on the pressing plate 900;

[0072] 4. Pass the guide block 903 on the pressure plate 900 through the cushion guide groove 105 and finally into the partition guide groove 205.

[0073] 5. Place a screw in the counterbore 901 , pass through the through hole 106 , and finally tighten it to the non-magnetic nut 206 .

[0074] Example 3

[0075] The difference between this embodiment and embodiment 1 is that the structure of the fixing unit is different. The fixing unit in this embodiment fixes the partition unit more stably, see Fig. 9 As shown, the locking hole 304 on the fixing seat 301 and the fixing hole 207 on the partition unit 200 are connected by screws. The buckle 302 is fixed to the fixing seat 301. After the buckle 302 is inserted into the clamping groove 401, the buckle 302 is deformed to generate a clamping force on the clamping groove 401, so that the partition unit 200 can be quickly installed on the treatment device 400. Similarly, the partition unit 200 can be quickly removed from the treatment device 400. The buckle 302 is a general product, a plastic material, and can be directly purchased on the market.

[0076] The fixing seat 301 and the buckle 302 are realized by the contact between the fixing edge 305 and the buckle interlayer 306. Fig.10 As shown, after the buckle 302 is installed on the fixing seat 301, when the buckle 302 is pulled out, the buckle interlayer 306 on the buckle 302 will be blocked by the fixing edge 305, making it difficult to be pulled out.

[0077] Usage and steps

[0078] 1. Add gasoline to the treatment equipment and extract the gas in the oil;

[0079] 2. The treatment equipment is placed on the MRI bed;

[0080] 3. Inject a small amount of water into the sound-transmitting membrane 500 and lay the sound-transmitting soft membrane 600 inside the sound-transmitting membrane 500. Use a scraper to remove the bubbles between the sound-transmitting membrane 500 and the sound-transmitting soft membrane 600 to promote the coupling between the two membranes.

[0081] 4. Install the quick-disassembly anti-overflow magnetic resonance compatible baffle assembly above the sound-permeable soft membrane 600. The buckle 302 on the quick-disassembly anti-overflow magnetic resonance compatible baffle can be quickly clipped to the treatment device. At this time, the buckle 302 is slightly deformed, generating an anti-slip force to ensure the stability of the installation.

[0082] 5. The human body 700 lies prone on the treatment device.

[0083] 6. Use the restraint belt 800 to fix the human body to prevent the human body from moving.

[0084] 7. Inject coupling liquid into the sound-transmitting soft membrane 600. When there is too much coupling liquid, the coupling liquid will be recovered to the designated position of the treatment device through the guide hole 202 and finally discharged.

[0085] 8. Control the MRI bed to enter the designated MRI position and carry out subsequent treatment steps.
