[0025] Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following embodiments are provided to further illustrate this disclosure in detail. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit this disclosure.

[0027] In one exemplary embodiment, see Figure 3This disclosure provides a lighting device installed on the inner wall 04 of a magnetic resonance imaging (MRI) tube. The lighting device is placed within an opening in the inner wall 04 of the MRI tube and includes a lamp holder 01, a light-emitting module (taking an LED light panel 03 as an example), and a lamp cover 02. The light-emitting module is fixed to the lamp holder 01, and the lamp cover is detachably fixed to the lamp holder 01 and covers the light-emitting module, allowing the light emitted by the light-emitting module to shine outwards through the lamp cover. The shape of the outer wall of the lamp holder 01 conforms to the opening, facilitating the placement of the lighting device within the opening. The lamp holder 01 has a pair of elastic latches 011 that contact the inner wall of the opening. When force is applied, the elastic latches 011 move towards each other, presenting a retracted first state relative to the lamp holder 01. In the first state, since there is no obstruction from the elastic latches 011, the lamp holder 01 can enter or exit the opening. Therefore, when installing the lighting device, the elastic latches 011 are compressed to the first state, thereby inserting the lighting device into the opening. The elastic clip 11 can be compressed using a tool or by hand, or by setting a bevel on the outer side of the elastic clip 011. Through the combined action of the force applied to the lamp holder 01 during insertion and the bevel, the elastic clip 011 is automatically compressed to its first state during the insertion process. After the lamp holder 01 is placed into the opening, the elastic clip 011 will release, meaning each elastic clip 011 moves away from the other, extending relative to the lamp holder 01. At this point, the elastic clip 011 abuts against the corresponding receiving part on the inner wall of the opening, forming a binding force with the receiving part, thereby fixing the lamp holder 01 within the opening. In the second state, the elastic clip 011 can be in a completely free state or in a compressed state with a lesser degree of compression than the first state, as long as it can combine with the receiving part and provide a fixing effect on the lamp holder 01 within the opening. In order to remove the lamp holder 01 from the opening, the elastic clip 011 has a part that is fixed in the opening and also protrudes from the opening. By operating on this part, the elastic clip 011 can be compressed back to the first state, thereby making it easy to remove the lamp holder 01 from the opening and facilitating the replacement of the entire lighting module.

[0028] In one exemplary embodiment, see continue to see Figure 3A receiving space is formed within the lamp holder 01, and the light-emitting module is fixed within this space. The receiving space has an opening, and the lampshade 02 is detachably installed at the opening. Two elastic clips 011 are located on opposite sides of the opening. During movement, the two elastic clips 011 cause the outer diameter of the lamp holder 01 to increase and decrease, correspondingly increasing and decreasing the inner diameter of the opening of the lamp holder 01. Specifically, by compressing the elastic clips 011 to a first state, on the one hand, the elastic clips 011 retract, reducing the outer diameter of the lamp holder 01, allowing the lamp holder 01 to enter / exit the opening; on the other hand, a portion of the elastic clips 011 enters the opening of the receiving space, reducing the inner diameter of the opening and preventing the lampshade from entering. Therefore, the first state is used to insert the lamp holder 01 into the opening. After the lamp holder 01 is inserted into the opening, the elastic clips 011 are released, allowing them to enter a second state due to their elasticity. In the second state, the elastic buckle 011 extends relative to the lamp holder 01 and abuts against the side wall of the opening, thus fixing the lamp holder 01. Optionally, to further fix the lamp holder 01, a lamp holder nut fixing seat 012 is provided on the back of the lamp holder 01, and a lamp holder fixing structure 015 is correspondingly provided on the inner side of the lamp holder 01. After the lamp holder 01 reaches the fixed position, a nut is passed through the lamp holder nut fixing seat 012 and the lamp holder fixing structure 015 to fix the lamp holder 01 onto the magnetic resonance equipment. After fixing the lamp holder 01, the LED lamp board 03 is fixed into the receiving space of the lamp holder 01. First, the electrical interface of the LED lamp board 03 is inserted into the LED lamp board interface 019, and then the LED lamp board 03 is fixed to the LED lamp board fixing structure 014 (which can be an isolation post) of the lamp holder 01 using screws. At this point, the elastic clip 011 is still in its second state. The elastic clip 011 is disengaged from the opening of the receiving space, allowing the lampshade 02 to enter the opening. Therefore, after fixing the LED light board 03, the lampshade 02 can be fixed to the opening of the receiving space. The elastic clip 011 has a lampshade contact surface that contacts the lampshade 02. In the second state, the lampshade contact surface of the elastic clip 011 abuts against the lampshade 02. The lampshade contact surface allows the lampshade 02 and the lamp holder 01 to fit tightly together, preventing gaps that would cause unsightly damage and dust ingress. This contact can exert a certain force, fixing the lampshade 02 in place, ensuring that the lampshade 02 and the lamp holder 01 are held together solely by the force of the elastic clip 011. Of course, this contact can also be a forceless contact, using other structures to fix the lampshade 02 to the opening of the lamp holder 01.

[0029] In one exemplary embodiment, see in particular Figure 3-8 The following describes in detail one method of fixing the lamp holder 01 and the lamp cover 02. The lamp holder 01 has a first slot 013 and a first protrusion 022, which are located on opposite inner sides of the opening (see in detail). Figure 7 ,exist Figure 7 In the opening, the first slot 013 and the first protrusion 22 are located on the left and right sides, respectively. Furthermore, the first slot 013 and the first protrusion 22 are not located on the same side of the opening as the elastic buckle 011. Correspondingly, the lampshade 02 has a second slot and a second protrusion 021. When the lampshade 02 is fixed to the lamp holder 01, the first protrusion 022 on the lamp holder 01 extends into the second slot on the lampshade 02, and the second protrusion 021 on the lampshade 02 extends into the first slot 013 on the lamp holder 01, thereby securing the lampshade 02 to the lamp holder 01.

[0030] In one exemplary embodiment, see Figure 3-8 See also Figure 7 This document describes in detail a method for easily detachable connection between the lamp holder 01 and the lamp cover 02. The lamp holder 01 has a resilient tongue 017, with a first protrusion 022 located on the resilient tongue 017. The resilient tongue 017 has an operating surface that can contact a flathead screwdriver 300. In the free state, there is a gap between the operating surface and the corresponding side of the lamp cover 02; this gap is a disassembly hole 016, facilitating the insertion of the flathead screwdriver 300. Furthermore, the operating surface of the resilient tongue 017 can be an inclined surface. When the screwdriver 300 is inserted, the inclined surface is subjected to a force in a first direction, causing the resilient tongue 017 to move in a second direction different from the first direction. Figure 7 In the first direction, the direction is vertical, and the direction is horizontal. The movement of the elastic tongue 017 causes the first protrusion 022 to leave the second slot. The screwdriver 300 continues to extend into the bottom of the lamp cover 02, which can easily pry the lamp cover 02 off the lamp holder 01, thereby removing the lamp cover 02 from the lamp holder 01 and exposing the LED light panel 03.

[0031] In one exemplary embodiment, a magnetic resonance imaging (MRI) device is provided. The MRI device includes an illumination device for the inner cylinder of the aforementioned MRI device, and an opening is made in the inner cylinder to house the illumination device. To fix the illumination device in the opening, the inner wall of the opening has a receiving portion for a snap-fit ​​elastic buckle 011. The receiving portion can be a recess or, as shown in the example, […]. Figure 3 The inclined surface shown is sufficient as long as the receiving part allows the elastic buckle 011 to be in the second state after the lamp holder 01 enters the opening.

[0032] In one exemplary embodiment, first refer to Figure 1 The illumination module 10 is fixed on the inner cylinder 20 of the magnetic resonance imaging system. Multiple positions are available, and the arrangement can be tailored to the purpose of the illumination module 10 and the length and diameter of the magnet and cylinder. For example, to avoid direct light stimulation to the examined eye, the lamp can be positioned as shown in the middle diagram. However, if interventional surgery is required and higher light intensity is needed, the arrangement of the illumination module 10 is not limited to this specific configuration. Figure 1The three methods are shown. See also... Figure 2 , Figure 2 The illustrated embodiment uses fixing bolts 104 to secure the lighting lamp 101 to a designated position on the magnetic resonance tube wall 200 within the magnetic resonance scanner gantry. First, the lamp holder fixing plate 103 is placed behind the magnetic resonance tube wall 200, and then the fixing bolts 104 are used to secure the lamp holder fixing plate 103 and the lamp cover 102. During fixing, since the lamp cover surface is typically not equipped with screw holes for aesthetic purposes, the fixing bolts 104 must be operated from the rear side of the magnetic resonance tube wall 200. This lighting device structure is inconvenient. When installing the lighting device, the magnetic resonance tube wall 200 cannot be placed inside the magnetic resonance equipment; the lighting device must be installed first before the magnetic resonance tube wall 200 is pushed into the magnetic resonance equipment. Furthermore, maintenance of the lighting device requires first removing the magnetic resonance tube wall 200, making both installation and maintenance very inconvenient.

[0033] In one exemplary embodiment, see Figure 3-8 This invention provides a lighting device that is easy to fix and can be quickly installed. First, the LED light panel 03 (the light source is not limited to LED light panels; other available light sources are also acceptable) is fixed to the lamp holder 01 by bolts. Then, the lamp holder 01 is directly pressed into the pre-drilled square hole in the inner wall of the magnetic resonance tube 04. After pressing, the elastic clip 011 on the lamp holder 01 returns to its initial state from its elastic deformation state, thus fixing it to the inclined surface of the square hole in the inner wall of the magnetic resonance tube 04. Finally, the lampshade 02 is pressed into the lamp holder 01, and the pre-drilled clip (i.e., the second protrusion 021) on the lampshade 02 presses into the first slot 013 pre-drilled on the lamp holder 01. The side wall of the lampshade 02 fits precisely against the inner side of the elastic clip 011, thus restricting the inward displacement of the elastic clip 011 and firmly fixing the lamp holder 01 in the square hole of the inner wall of the magnetic resonance tube 04. Optionally, additional threaded fixing from the back is no longer required. During disassembly and assembly, first remove the lampshade 02, and then the lamp holder 01 can be easily removed from the square hole. Regarding the connection structure between the lampshade 02 and the lamp holder 01, the lampshade 02 is fixed inside the lamp holder 02 by elastic clips (here, the second protrusion 021 and the first protrusion 022). During disassembly, use a flathead screwdriver 30 to insert into the disassembly / removal hole 018, deforming the first protrusion 022 to allow it to disengage from the lampshade 02. At this point, the lampshade 02 can be separated from the lamp holder.
