Description

Technical Field

[0001] The present invention relates to the technical field of head-mounted medical shadowless lamps, and particularly relates to a head-mounted medical shadowless lamp. Background Art

[0002] Although traditional surgical shadowless lamps have played an important role in the operating room, they are large in size and inconvenient to move. In some surgeries that require delicate operations, such as otolaryngology and dentistry, it is difficult to meet the high-precision requirements of doctors for the surgical field of view. In addition, the light sources of traditional shadowless lamps are mostly halogen lamps, which have problems such as high energy consumption, short lifespan, and large heat generation.

[0003] With the continuous development of medical technology, minimally invasive surgery and precision medicine have gradually become the mainstream. These surgeries usually require operations in smaller incisions or cavities, which pose higher requirements for the brightness, uniformity, and shadowless effect of the light source. Head-mounted medical shadowless lamps, with their small and portable characteristics, can provide more flexible lighting support for doctors and meet the needs of minimally invasive surgery and precision medicine.

[0004] In recent years, the rapid development of LED technology has provided a technical basis for the invention of head-mounted medical shadowless lamps. LED light sources have the advantages of high efficiency, long lifespan, environmental protection and energy saving, and the color temperature can be adjusted to provide different lighting environments according to surgical needs. In addition, the cold light characteristics of LED light sources reduce the heat radiation during the operation and reduce the damage to the patient's tissues. However, most of the existing shadowless lamp light sources are installed on the head-mounted bracket in a fixed manner. During the operation, doctors need to frequently lower their heads to adjust the irradiation angle of the light source. During the process of lowering the head multiple times, the head-mounted bracket is prone to loosen and even fall off. Moreover, when doctors pick up surgical instruments in the on-light state, the light is easily reflected onto the highly reflective surgical instruments, generating glare, resulting in doctor visual fatigue and even affecting the operation of the surgery.

[0036] An embodiment of the present invention discloses a head-mounted medical shadowless lamp.

[0037] Embodiment 1

[0038] Refer to Figures 1-9, which is the first embodiment of the present invention, provides a head-mounted medical shadowless lamp. This head-mounted medical shadowless lamp includes a head-mounted bracket body 1. There is also an assembly component 2 on the head-mounted bracket body 1 that is driven by a driving component 4 and is used to adjust the angle of the lighting module 3. Above the lighting module 3 on the assembly component 2, there is an anti-glare component 5 to prevent glare. There is also an anti-detachment component 6 for adjusting the tightness on the head-mounted bracket body 1. A mounting buckle 101 is fixedly installed on the head-mounted bracket body 1, and the head-mounted bracket body 1 is connected to a longitudinal headband 102 through the mounting buckle 101. On both sides of the mounting buckle 101 and on the head-mounted bracket body 1, there are symmetrically distributed lateral adjustment parts 601. On the longitudinal headband 102, there is a longitudinal adjustment part 602. The assembly component 2 includes an assembly seat 201 fixedly installed on the mounting buckle 101. A T-shaped bracket 202 is fixedly installed on the assembly seat 201 by screws. One end of the T-shaped bracket 202 away from the assembly seat 201 is movably connected to symmetrically distributed deflection seats 203. And at one end of the deflection seat 203 close to the T-shaped bracket 202, there is a rotating shaft 2031. And both deflection seats 203 are hinged to the T-shaped bracket 202 through the rotating shaft 2031. And the deflection seats 203 are symmetrically fixed at both ends of the rotating shaft 2031. Between the deflection seat 203 and the T-shaped bracket 202, there is also a gear 2032 fixedly installed on the rotating shaft 2031. One end of the deflection seat 203 away from the rotating shaft 2031 is fixedly installed with a light source guide rail 204. The lighting module 3 includes energy-saving LED shadowless lamps 301 movably connected to both ends of the light source guide rail 204. Between the light source guide rails 204, there is also a power supply 302 for supplying power to the energy-saving LED shadowless lamps 301. The head-mounted bracket body 1 is the basic structure of the entire head-mounted medical shadowless lamp, which is in a ring-shaped belt structure with a certain basic width and is used to be sleeved on the head. It is made of lightweight and high-strength materials and can be slightly bent and deformed within a certain range to adapt to the user's head shape. The mounting buckle 101 is used to provide an installation basis for the assembly seat 201. The T-shaped bracket 202 is fixed to the assembly seat 201 by screws. According to the actual use situation, T-shaped brackets 202 with different lengths can be replaced to change the distance between the light source and the user. The deflection seat 203 is hinged to the T-shaped bracket 202 through the rotating shaft 2031, and the rotating shaft 2031 penetrates through the entire T-shaped bracket 202 and can rotate in the T-shaped bracket 202. The gear 2032 can drive the deflection seat 203 connected to the rotating shaft 2031 to rotate around the rotating shaft 2031 under the drive of the driving component 4, and then drive the angle change of the energy-saving LED shadowless lamp 301 installed on the light source guide rail 204 on the deflection seat 203. And by changing the rotation direction of the gear 2032, different angle deflections of the energy-saving LED shadowless lamp 301 can be realized, so that the doctor does not need to lower his head multiple times to complete the adjustment of the irradiation angle. And using the energy-saving LED shadowless lamp 301 as the light source of the medical shadowless lamp and cooperating with the power supply 302 for power supply, an integrated design of charging and lighting can be realized, and it can work continuously for ten hours.The structure is lightweight and equipped with sensors inside. The brightness can be adjusted. The energy-saving LED shadowless lamp 301 is required to meet medical standards and needs to be disinfected and sterilized after use.

[0039] The driving component 4 includes a first push rod 401 fixedly installed on the assembly seat 201. The piston rod of the first push rod 401 is connected to a U-shaped slider 402 located below the T-shaped bracket 202. The top of the U-shaped slider 402 is fixedly installed with transmission racks 404 that are symmetrically distributed and meshed with the gears 2032 respectively. One end of the transmission rack 404 extends into the assembly seat 201. The first push rod 401 can push the U-shaped slider 402 to move along the axis of the T-shaped bracket 202 through the extension of the piston rod, and at the same time drive the transmission rack 404 to rotate meshingly with the corresponding gear 2032, thereby realizing the synchronous rotation of the gears 2032 at both ends of the rotating shaft 2031 and ensuring the stability during the adjustment of the irradiation angle.

[0040] Both ends of the U-shaped slider 402 are also installed with guide shafts 403 that are parallel to the transmission rack 404. One end of the guide shaft 403 passing through the U-shaped slider 402 is fixedly installed in the assembly seat 201. And a second push rod 405 perpendicular to the first push rod 401 is also fixedly installed in the assembly seat 201. The guide shaft 403 fixed in the assembly seat 201 ensures the stable movement of the U-shaped slider 402 while further ensuring the full meshing of the transmission rack 404 and the gear 2032.

[0041] Both ends of the light source guide rail 204 are movably connected to light source seats 205 corresponding to the energy-saving LED shadowless lamp 301. And a chute 2041 for limiting the movement of the light source seat 205 is provided in the light source guide rail 204. One end of the light source seat 205 away from the energy-saving LED shadowless lamp 301 is provided with a bidirectional screw 2051. The two ends of the bidirectional screw 2051 are respectively in threaded fit with the corresponding light source seats 205. A protective rubber sleeve 2052 is sleeved outside the bidirectional screw 2051 and between the light source seats 205. The energy-saving LED shadowless lamp 301 is installed on the light source guide rail 204 through the light source seat 205 and can move limitly in the chute 2041 following the light source seat 205. A hollow opening for the movement of the bidirectional screw 2051 is provided in the T-shaped bracket 202, and the bidirectional screw 2051 never contacts the T-shaped bracket 202. According to actual use requirements, the bidirectional screw 2051 can be rotated by grasping the protective rubber sleeve 2052, so that the thread-connected light source seats 205 can move away from or close to each other in the chute 2041, thereby completing the adjustment of the distance between the energy-saving LED shadowless lamps 301 and changing the overall lighting range.

[0042] The anti-glare component 5 includes an L-shaped bracket 501 fixedly installed on the assembly seat 201. One end of the L-shaped bracket 501 is hinged to a light-shielding plate 502. An absorbent coating 5021 is provided on the side of the light-shielding plate 502 close to the energy-saving LED shadowless lamp 301. The end of the L-shaped bracket 501 away from the light-shielding plate 502 is fixedly installed with a column 503 parallel to the second push rod 405. A support shaft 5031 is movably connected in each column 503, and the end of the support shaft 5031 extending outside the column 503 is hinged inside the light-shielding plate 502. The light-shielding plate 502 is also hinged to the piston rod of the second push rod 405. The L-shaped bracket 501 provides support for the light-shielding plate 502. In the normal use state, the light-shielding plate 502 is parallel to the T-shaped bracket 202 to avoid interfering with normal lighting. When anti-glare is required, it deflects downward with the L-shaped bracket 501 as the center, and the absorbent coating 5021 absorbs or scatters light to reduce the reflectivity of light and reduce glare. The column 503 is at the same height as the highest end of the L-shaped bracket 501, which can provide support when the light-shielding plate 502 is not deflected, and further limit the angle of the deflected light-shielding plate 502 through the support shaft 5031 when the light-shielding plate 502 deflects. The second push rod 405 can push the light-shielding plate 502 to deflect through the extension of the piston rod.

[0043] A baffle 504 is fixedly installed between the L-shaped bracket 501 and the column 503, and the baffles 504 are symmetrically distributed below the light-shielding plate 502. A control button 5041 electrically connected to the first push rod 401 and the second push rod 405 respectively is also provided on the baffle 504. The baffle 504 shields the power part in the device to maintain beauty and safety, and the first push rod 401 and the second push rod 405 can be independently controlled through the control button 5041. The specific circuit connection relationship belongs to the commonly known means in the prior art and will not be elaborated here.

[0044] A control switch 3021 for controlling the energy-saving LED shadowless lamp 301 is provided on the power supply 302. A power transmission wire 3022 is also provided between the power supply 302 and the energy-saving LED shadowless lamp 301, and the power supply 302 is electrically connected to the corresponding energy-saving LED shadowless lamp 301 through the power transmission wire 3022. The control switch 3021 can control the corresponding energy-saving LED shadowless lamp 301 respectively, and under permitted conditions, only one energy-saving LED shadowless lamp 301 can be used for operation, so as to further reduce the energy consumption of the device. By means of power supply through the power transmission wire 3022, normal power supply can be ensured even when the distance between the energy-saving LED shadowless lamps 301 is adjusted.

[0045] The lateral adjustment member 601 includes a lateral tension buckle 6011 fixedly installed on the head-mounted bracket body 1. A lateral strap 6012 for adjusting the tightness of the head-mounted bracket body 1 is further provided in the lateral tension buckle 6011, and lateral gaskets 6013 are wrapped around the lateral tension buckle 6011. The longitudinal adjustment member 602 includes a longitudinal tension buckle 6021 fixedly installed on the longitudinal headband 102. A longitudinal strap 6022 for adjusting the tightness of the longitudinal headband 102 is further provided in the longitudinal tension buckle 6021, and longitudinal gaskets 6023 are wrapped around the longitudinal tension buckle 6021. The longitudinal headband 102 is connected to the head-mounted bracket body 1 through an assembly buckle 101 to further fix the head-mounted medical shadowless lamp and ensure its stability during the operation. The lateral strap 6012 can be drawn out from the lateral tension buckle 6011, and as the length increases, the tightness of the head-mounted bracket body 1 becomes greater. The longitudinal strap 6022 can be drawn out from the longitudinal tension buckle 6021, and as the length increases, the tightness of the longitudinal headband 102 becomes greater. The friction during the process of adjusting the tightness is reduced through the lateral gaskets 6013 and the longitudinal gaskets 6023, thereby ensuring the comfort and stability of wearing.

[0046] When wearing is required, the user puts the head-mounted bracket body 1 on the head, adjusts the tightness of the head-mounted bracket body 1 by drawing out the lateral strap 6012 from the lateral tension buckle 6011, draws out the longitudinal strap 6022 from the longitudinal tension buckle 6021 to adjust the tightness of the longitudinal headband 102, and ensures the comfort and stability of wearing through the lateral gaskets 6013 and the longitudinal gaskets 6023, thereby reducing the probability of the device loosening and falling off.

[0047] When the angle needs to be adjusted, through the extension of the piston rod of the first push rod 401 in the driving assembly 4, the U-shaped slider 402 is pushed to move. At the same time, the driving rack 404 is driven to rotate meshingly with the corresponding gear 2032, thereby realizing the synchronous rotation of the gears 2032 at both ends of the rotating shaft 2031. Further, the full meshing of the driving rack 404 and the gear 2032 is ensured through the guide shaft 403, so that the gear 2032 drives the deflection seat 203 connected to the rotating shaft 2031 to rotate around the rotating shaft 2031, thereby driving the angle change of the energy-saving LED shadowless lamp 301 installed on the light source guide rail 204 on the deflection seat 203. By changing the rotation direction of the gear 2032, different-direction angle deflections of the energy-saving LED shadowless lamp 301 can be realized, so that the doctor can complete the adjustment of the irradiation angle without having to lower the head multiple times.

[0048] Moreover, an energy-saving LED shadowless lamp 301 meeting medical standards is used in cooperation with a power supply 302 for power supply. The integrated design of charging and lighting can be achieved, and it can work continuously for ten hours. It is light in structure and is equipped with sensors inside. The brightness can be adjusted. According to actual usage requirements, by grasping the anti-slip rubber sleeve 2052 and rotating the bidirectional screw 2051, the light source seats 205 connected by threads move away from or close to each other in the sliding groove 2041, so as to complete the adjustment of the distance between the energy-saving LED shadowless lamps 301 powered by the power supply 302 through the power transmission wire 3022, change the overall lighting range, and the corresponding energy-saving LED shadowless lamps 301 can be controlled respectively through the control switch 3021. Under permitted conditions, a single LED shadowless lamp 301 can be used for lighting, so as to further reduce the energy consumption of the device;

[0049] When it is necessary to pick up instruments that may produce glare, the extension of the piston rod of the second push rod 405 pushes the light-shielding plate 502 initially distributed in parallel with the T-shaped bracket 202 to deflect. The light-shielding plate 502 is separated from the column 503. The angle of the deflected light-shielding plate 502 is further restricted by the support shaft 5031 extending from the column 503, and the light-absorbing coating 5021 on the light-shielding plate 502 absorbs or scatters light to reduce the light reflectivity, so as to effectively reduce glare. During this process, the control buttons 5041 on the baffle 504 that shields the power part in the device can respectively achieve independent control of the first push rod 401 and the second push rod 405.
