Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a fixable medical oral lighting lamp. Background Art

[0002] In dental care settings, existing medical oral lighting generally relies on external lamp head angle adjustment to control the lighting range. The refractive structures of traditional lighting, such as fixed reflectors and static light guides, are fixed designs and cannot dynamically adjust the degree of light convergence based on treatment depth, such as deep root canals and narrow areas like wisdom tooth pockets. When localized illumination brightness needs to be enhanced, the only option is to increase the overall light source power, resulting in increased energy consumption and the risk of overheating. During shallow treatments, strong light can irritate the patient's oral mucosa, and existing technologies lack a solution for achieving stepless adjustment of light convergence through mechanical structures.

[0003] At the same time, existing devices rely on the overall swing of the lamp head to adjust the lighting angle, but the relative position of the light source and the refraction component is fixed. As a result, the actual illumination angle is affected by the swing trajectory of the lamp head housing, resulting in an error in the "adjusted angle and actual light path angle" error. Especially in the confined oral space, when doctors need to precisely illuminate delicate areas such as interdental spaces and gingival sulci, slight movements of the external structure or deformation of the patient's mouth can further amplify this angle deviation, resulting in blind spots or ineffective lighting.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Reference Figures 1 to 4 , which is the first embodiment of the present invention, provides a fixable medical oral lighting lamp.

[0037] Specifically, it includes a reclining chair 101;

[0038] The main assembly 200 is provided on the outer wall of the recliner 101 and includes a lamp arm 201 and a lighting lamp housing 202 provided at the end of the lamp arm 201. The inner wall of the lighting lamp housing 202 is provided with a lamp shade 2021, and the inner wall of the lamp shade 2021 is provided with a lamp head 203. The outer wall of the lamp head 203 is provided with an array of refraction plates 2031.

[0039] An adjustment component is provided on the outer wall of the lamp head 203 and the adjustment component includes a servo motor 204 provided on the inner wall of the lampshade 2021. The adjustment component is driven by the servo motor 204 to adjust the angle of the lamp head 203 on the inner wall of the lampshade 2021. The outer wall of the refraction plate 2031 is also hinged with a hinged rod 403 and the hinged rod 403 is driven by the adjustment component to adjust the state of the refraction plate 2031 on the outer wall of the lamp head 203 to change the degree of light convergence.

[0040] Among them, the lamp arm 201 is adjustable, and the multiple sections of the lamp arm 201 are connected by rotating joints, so that the top lighting lamp housing 202 can be freely moved, rotated and adjusted in a certain range, which is convenient for doctors to flexibly adjust the angle and position of the internal lamp head 203 during lighting according to different treatment positions and angle requirements. The refraction plate 2031 outside the lamp head 203 is used to converge the light emitted by the lamp head 203, improve the concentration of the light, and make the light more effectively projected to the oral treatment area.

[0041] The adjusting component is installed inside the lampshade 2021. The servo motor 204 serves as the power source of the adjusting component and is started and stopped by an external control panel. The refraction plate 2031 is hinged on the outer wall of the lamp head 203 and can be flipped to change the angle between it and the lamp head 203. It can gather inward to focus the divergent light into a narrow beam, thereby increasing the brightness of the light. It is suitable for scenes such as root canals and deep wisdom teeth that require strong light penetration. The refraction plate 2031 can also be unfolded to radiate light in a flat state to expand the lighting range. At this time, it is suitable for panoramic oral examinations or shallow treatments.

[0042] At the same time, the angle of the lamp head 203 inside the lighting lamp housing 202 can be slightly changed by adjusting the components. When the lamp arm 201 and the lighting lamp housing 202 remain unchanged, the angle of the internal lamp head 203 is changed, so that the internal light path can be deflected to the buccal or lingual side alone, accurately illuminating hidden parts such as the distal and mid-surfaces of the molars. The irradiation angle of the light is adjusted more accurately, avoiding the actual irradiation angle being affected by the swing trajectory of the lighting lamp housing 202 due to adjustment of the lamp arm 201, and reducing the error between the adjustment angle and the actual light path angle.

[0043] Example 2

[0044] Reference Figures 6 to 11 , which is the second embodiment of the present invention, and is implemented based on the previous embodiment.

[0045] Specifically, the adjusting component also includes a moving base plate 301 arranged on the outer wall of the lamp head 203, a transmission shaft 205 is arranged at the axis center of the moving base plate 301, and a clamping block 2052 arranged at the end of the transmission shaft 205 is located in a limiting sleeve 3012 arranged at the end of the moving base plate 301, and the other end of the transmission shaft 205 is sleeved on the outer wall of the rotating shaft 2041 at the axis center of the servo motor 204, a limiting block 2042 is provided on the outer wall of the rotating shaft 2041, and the end of the limiting block 2042 extends to the inner wall of the limiting groove 2051 opened at the end of the transmission shaft 205 and slides with it.

[0046] Among them, the moving base plate 301 is installed on the side away from the light source of the lamp holder 203 and is not fixedly connected to the lamp holder 203. At the same time, the clamping block 2052 at the bottom of the transmission shaft 205 is installed inside the limiting sleeve 3012 at the bottom of the moving base plate 301, but the transmission shaft 205 is not in direct contact with the moving base plate 301, and the movement of the transmission shaft 205 will not affect the moving base plate 301.

[0047] The limiting block 2042 on the outer wall of the rotating shaft 2041 slides inside the limiting groove 2051 , so that the transmission shaft 205 can move up and down outside the rotating shaft 2041 and rotate synchronously with the rotating shaft 2041 .

[0048] Preferably, a mounting sleeve 303 is installed on the outer wall of the moving base plate 301, a connecting ring 304 is provided on the inner wall of the mounting sleeve 303, and an array of spring pieces 3042 are provided on the outer wall of the connecting ring 304, and the other end of the spring piece 3042 is connected to the inner wall of the mounting sleeve 303 to push the connecting ring 304 away from the mounting sleeve 303.

[0049] Among them, the mounting shell 303 is fixed on the surface of the moving base plate 301, one end of the spring piece 3042 is fixed on the inner surface of the mounting shell 303, and the other end is fixed on the surface of the connecting ring 304. The spring piece 3042 makes the connecting ring 304 away from the inner wall of the mounting shell 303 in the initial state. When the connecting ring 304 is driven to approach the inner wall of the mounting shell 303, the spring piece 3042 will be deformed. When the external force is lost, the spring piece 3042 will synchronously return to the position away from the mounting shell 303 under the reset drive of the spring piece 3042.

[0050] A friction plate 302 is provided at the end of the connecting ring 304, and the friction plate 302 is pushed by the connecting ring 304 to be close to the end face of the moving base plate 301. A clamping groove 3021 is provided on the end face of the friction plate 302, and the clamping groove 3021 is opposite to the clamping block 2052. A first elastic member 2053 is provided at the end of the clamping block 2052, and the first elastic member 2053 is used to push the clamping block 2052 to clamp with the clamping groove 3021. The clamping block 2052 drives the friction plate 302 and the rotating shaft 2041 to rotate synchronously.

[0051] Among them, the friction plate 302 is located in the middle of the moving base plate 301 and the connecting ring 304. The connecting ring 304 is influenced by the elastic force of the spring piece 3042 to push the friction plate 302 toward the surface of the moving base plate 301 and adhere to it tightly. The clamping groove 3021 opened at the axis center of the lower surface of the friction plate 302 is opposite to the clamping block 2052 at the bottom of the transmission shaft 205. In the initial state, under the influence of the first elastic member 2053, the clamping block 2052 is engaged in the inside of the clamping groove 3021, and the friction plate 302 is driven by the clamping block 2052 to rotate synchronously with the rotating shaft 2041. At this time, since the friction plate 302 is pushed close to the moving base plate 301 by the connecting ring 304, the moving base plate 301 rotates together.

[0052] The friction plate 302 is in close contact with the end face of the moving base plate 301 and drives the moving base plate 301 to rotate. The outer wall of the moving base plate 301 is also provided with a spiral guide rail 3011. The end face of the lamp holder 203 is also provided with a mounting pillar 2033 and the inner wall of the mounting pillar 2033 is hinged with a hinged rod 403. A half gear 4031 is provided at the end of the hinged rod 403 and the half gear 4031 cooperates with the spiral guide rail 3011. The other end of the hinged rod 403 is hinged to the outer wall of the refraction plate 2031. The hinged rod 403 is used to drive the refraction plate 2031 to flip on the outer wall of the lamp holder 203 to change the degree of light convergence.

[0053] Among them, the mounting pillar 2033 fixed on the back of the lamp holder 203 is used to install the hinged rod 403, and the half gear 4031 at the top of the hinged rod 403 cooperates with the spiral guide rail 3011 on the outer wall of the moving base plate 301. When the moving base plate 301 rotates, the spiral guide rail 3011 rotates together and drives the half gear 4031 to rotate inside the mounting pillar 2033. At this time, the other end of the hinged rod 403 and the end hinged to the back of the refraction plate 2031 rotate with the half gear 4031 as the axis, driving the refraction plate 2031 to flip over outside the lamp holder 203. Through the movement of the refraction plate 2031 outside the lamp holder 203, the brightness of the divergent light of the lamp holder 203 is changed.

[0054] Preferably, the end face of the connecting ring 304 is also provided with an elastic ring 305, and the outer wall of the connecting ring 304 is also provided with a snap plate 3041 for limiting the elastic ring 305, the inner wall array of the elastic ring 305 is provided with a rocker 3051 and the end of the rocker 3051 is in contact with the end of the fixed ring 206 fixed to the outer wall of the transmission shaft 205, the inner wall of the elastic ring 305 is provided with a limiting nail column 3052, the end of the limiting nail column 3052 extends to the outer wall of the mounting sleeve 303 and is provided with a nail head 3053, the end face of the elastic ring 305 is provided with a first ring 306 and a second ring 3061, the first ring 306 and the second ring 3061 are embedded in the outer wall of the limiting nail column 3052.

[0055] Among them, the elastic ring 305 is installed on the upper surface of the connecting ring 304, located between the connecting ring 304 and the mounting sleeve 303. The inner wall array of the elastic ring 305 is equipped with multiple seesaws 3051. The top of the seesaw 3051 is higher than the height of the elastic ring 305. The limiting nail column 3052 is located at the connection between the seesaw 3051 and the elastic ring 305. At the same time, the nail head 3053 at the bottom of the limiting nail column 3052 is fixed to the surface of the mounting sleeve 303, so that the limiting nail column 3052 cannot move.

[0056] When the first and second rings 306 and 3061 are respectively installed above and below the elastic ring 305, they are embedded in the side walls of the limiting nail column 3052 and cannot move due to the influence of the limiting nail column 3052. At the same time, when the top of the rocker plate 3051 is squeezed downward, it moves with the first and second rings 306 and 3061 as fulcrums, and the side of the elastic ring 305 tilts upward. Since the side of the elastic ring 305 is limited by the snap plate 3041, when the side of the elastic ring 305 tilts up, the snap plate 304 drives the connecting ring 304 to move upward, close to the inner wall of the mounting shell 303 and deforming the spring piece 3042. Since the connecting ring 304 moves upward, the connecting ring 304 loses its pushing effect on the friction plate 302. The friction plate 302 is not tightly attached to the moving base plate 301, and the rotation of the friction plate 302 cannot drive the moving base plate 301 to rotate.

[0057] In summary, when in use, the servo motor 204 is started, and the rotating shaft 2041 slides in the limiting groove 2051 through the limiting block 2042 to drive the transmission shaft 205 to rotate. The limiting block 2042 does not affect the rotation synchronization when sliding in the limiting groove 2051. Under the action of the first elastic member 2053, the clamping block 2052 at the bottom of the transmission shaft 205 is clamped into the clamping groove 3021 of the friction plate 302, driving the friction plate 302 to rotate with the transmission shaft 205. The connecting ring 304 is affected by the thrust of the spring piece 3042, pushing the friction plate 302 downward and close to the surface of the moving base plate 301, and driving the moving base plate 301 to rotate synchronously through friction.

[0058] The spiral guide rail 3011 on the outer wall of the moving base plate 301 rotates and engages with the half gear 4031, pushing the hinged rod 403 to swing with the mounting pillar 2033 as the fulcrum, driving the refraction plate 2031 to flip. When the refraction plate 2031 converges inward, the light converges into a narrow beam, and the brightness of the light is improved, which is suitable for deep treatment; when the refraction plate 2031 expands outward, the light diffuses into a wide beam, which is suitable for panoramic examination.

[0059] When the refraction plate 2031 does not need to be adjusted, the fixing ring 206 is pushed to squeeze the seesaw 3051 of the elastic ring 305. The top of the seesaw 3051 is pressed and bent downward. With the first ring 306 and the second ring 3061 as fulcrums, the side of the elastic ring 305 is driven to tilt upward, and the connecting ring 304 is pulled to move upward from the mounting housing 303 through the snap plate 3041. At this time, the spring piece 3042 is compressed and deformed.

[0060] The connecting ring 304 moves to separate the friction plate 302 from the moving base plate 301 , and the engaging block 2052 is disengaged from the engaging groove 3021 , so that the rotation of the transmission shaft 205 no longer drives the moving base plate 301 to rotate.

[0061] When the external force disappears, the spring piece 3042 returns to its original position and pushes the connecting ring 304 away from the mounting housing 303, and the friction plate is again pressed against the moving base plate, thereby resuming power transmission.

[0062] Example 3

[0063] Reference Figures 3 to 8 , which is the third embodiment of the present invention, is implemented based on the previous embodiment.

[0064] Specifically, a first concave ring 2061 and a second concave ring 2062 are provided at the end of the fixed ring 206, a first joint 2063 is provided at the end of the second concave ring 2062, a spiral sleeve 207 is also provided at the end of the transmission shaft 205, and the spiral sleeve 207 is located at the end of the fixed ring 206, a connector 2071 is provided at the end of the spiral sleeve 207, and the connector 2071 is provided on the outside of the second concave ring 2062, and a second joint 2072 is provided on the inner wall of the connector 2071 and is opposite to the first joint 2063.

[0065] Among them, the fixed ring 206 is fixed on the outside of the transmission shaft 205, and the fixed ring 206 rotates synchronously with the transmission shaft 205. The spiral sleeve 207 is sleeved on the outside of the transmission shaft 205 and the connecting head 2071 at the bottom is sleeved on the inside of the second concave ring 2062. At the same time, the second joint 2072 inside the connecting head 2071 is opposite to the first joint 2063 on the lower surface of the second concave ring 2062, but in the initial state, the second joint 2072 is not engaged with the first joint 2063, and the fixed ring 206 will not drive the spiral sleeve 207 to rotate when it rotates with the transmission shaft 205.

[0066] Preferably, an electric push cylinder 401 is provided at the end of the mounting sleeve 303 and a push rod 402 is also provided at the end of the electric push cylinder 401. The other end of the push rod 402 extends to the inner wall of the first concave ring 2061 and cooperates with it. The push rod 402 is used to drive the fixed ring 206 to move on the inner wall of the spiral sleeve 207 so that the first joint 2063 and the second joint 2072 are engaged and drive the spiral sleeve 207 to rotate.

[0067] Among them, the electric push cylinder 401 is fixed to the upper surface of the mounting sleeve 303, and drives the fixed collar 206 and the transmission shaft 205 to move downward through the push rod 402. When the fixed collar 206 moves downward, it squeezes the top position of the rocker plate 3051, causing the outer edge of the side of the elastic ring 305 to tilt, driving the connecting ring 304 to move upward, so that the friction plate 302 is not in close contact with the surface of the moving base plate 301. At the same time, the transmission shaft 205 moves downward synchronously and the clamping block 2052 inside the limiting sleeve 3012 moves downward. When the clamping block 2052 moves downward, it loses the clamping effect with the clamping groove 3021. At this time, the rotation of the transmission shaft 205 will not drive the friction plate 302 to rotate, further avoiding the possibility of movement of the moving base plate 301. At this time, the hinged rod 403 and the refraction plate 2031 outside the moving base plate 301 are in a stationary state.

[0068] A fixing ring 208 is sleeved on the outer wall of the spiral sleeve 207 , and the fixing ring 208 is installed on the inner wall of the limiting ring 2023 on the inner wall of the lampshade 2021 . A fixing column 2081 is provided on the outer wall of the fixing ring 208 and extends to the inner wall of the limiting ring 2023 .

[0069] Among them, the limiting ring 2023 is fixed on the inner wall of the lampshade 2021, and while it does not move, it also restricts the fixing ring 208. Through the fixing column 2081 on the surface of the fixing ring 208, the fixing ring 208 cannot rotate when the spiral sleeve 207 rotates. When the spiral sleeve 207 rotates, it moves laterally on the inner wall of the fixing ring 208.

[0070] Preferably, the outer wall array of the limiting ring 2023 is provided with support columns 2022 and the support columns 2022 are fixed to the inner wall of the lampshade 2021, the inner wall of the support columns 2022 is provided with balls 2024, the outer wall of the balls 2024 is provided with connecting columns 2025 and the other end of the connecting columns 2025 is connected to the connecting block 2032 provided on the outer wall of the lamp head 203.

[0071] Among them, the support column 2022 is fixedly installed inside the lampshade 2021 and cannot move. At the same time, the bottom of the support column 2022 is attached to the backlight surface of the lamp head 203. The connecting block 2032 on the back of the lamp head 203 is located inside the support column 2022, and a ball 2024 is also provided inside the connecting block 2032 and inside the support column 2022. The two balls 2024 are connected by a connecting column 2025.

[0072] When the spiral sleeve 207 rotates inside the fixed ring 208, the position of the spiral sleeve 207 on the fixed ring 208 changes. Since the fixed ring 208 is fixed inside the lampshade 2021 and cannot move, when the spiral sleeve 207 rotates, it pushes the transmission shaft 205 to move outside the rotating shaft 2041, and the servo motor 204 changes the angle through the hinged plate 2043 at the bottom, pushing the lamp head 203 below to move relative to the support column 2022, and adjusting the angle between the lamp head 203 and the support column 2022, so that the ball 2024 inside the support column 2022 is displaced.

[0073] In summary, during use, when it is necessary to adjust the angle of the lamp head 203 inside the lighting lamp housing 202, the electric push cylinder 401 is started, and the push rod 402 extends into the first concave ring 2061, pushing the fixed ring 206 to move downward along the axial direction of the transmission shaft 205. When the fixed ring 206 moves downward, it will squeeze the rocker 3051 of the elastic ring 305, so that the side of the elastic ring 305 is upward, and drives the connecting ring 304 to move upward. At this time, the friction plate 302 is no longer tightly attached to the moving base plate 301, and the clamping block 2052 at the bottom of the transmission shaft 205 is no longer clamped with the clamping groove 3021, and will no longer drive the friction plate 302 to rotate, ensuring that the refraction plate 2031 remains stationary when adjusting the lamp head 203.

[0074] When the fixed collar 206 moves downward, the first joint 2063 of the fixed collar 206 engages with the second joint 2072 of the spiral sleeve 207, forming a rigid connection. The transmission shaft 205 then rotates the fixed collar 206, which in turn drives the spiral sleeve 207 through the engaged joint assembly. Since the fixed collar 208 restricts the spiral sleeve from rotating, its rotation is converted into axial thrust, pushing the transmission shaft 205 to move outside the rotating shaft 2041. As the transmission shaft 205 moves, it drives the servo motor 204 to deflect the angle through the hinge plate 2043.

[0075] The servo motor 204 drives the lamp head 203 to move relative to the support column 2022 . The ball 2024 in the support column 2022 cooperates with the connecting column 2025 , allowing the lamp head 203 to fine-tune its angle in space.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
