[0025] FIG3 is a schematic diagram of the electrical connection relationship of a surgical headlight provided in an exemplary embodiment of the present disclosure. DETAILED DESCRIPTION

[0026] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0027] In this disclosure, unless otherwise indicated, directional terms such as "upper, lower, left, and right" generally refer to the upper, lower, left, and right directions of the surgical headlight when in use. "Inside" and "outside" refer to the inside and outside of the outline of the relevant component. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not imply order or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same element.

[0028] As shown in Figures 1 to 3, the present disclosure provides a surgical headlight 100, which includes a head-mounted bracket 1, a driving device 2 and a plurality of lighting units 3. The head-mounted bracket 1 is used to be worn on the user's head. Each lighting unit 3 includes a mounting portion 31 and a lighting portion 32. The lighting portion 32 is movably connected to the mounting portion 31. The lighting unit 3 is detachably mounted on the head-mounted bracket 1 through the mounting portion 31, and the driving device 2 is connected to the lighting portion 32 of at least one lighting unit 3 so as to be able to drive the lighting portion 32 to move.

[0029] It should be noted that the lighting portion 32 of the lighting unit 3 in the embodiment of the present disclosure is movably connected to the mounting portion 31, which may mean that the lighting portion 32 is rotatably and / or movably connected to the mounting portion 31. Taking the lighting portion 32 being rotatably connected to the mounting portion 31 as an example, the lighting portion 32 may be connected to the mounting portion 31 by means of a ball joint connection structure, a bevel gear structure, or a universal joint rotating seat. Taking the lighting portion 32 being movably connected to the mounting portion 31 as an example, the lighting portion 32 may be connected to the mounting portion 31 by means of a telescopic rod, a connecting rod, or a slider groove structure. It can be seen that those skilled in the art can realize the movably connection of the lighting portion 32 to the mounting portion 31 according to relevant technologies, and the present disclosure does not limit its specific connection method.

[0030] The surgical headlight 100 is designed to be worn by medical personnel during surgery, providing illumination for the operating area. While the user is using the surgical headlight 100, the head-mounted bracket 1 of the surgical headlight 100 can be worn on the user's head to secure the surgical headlight 100. Multiple lighting units 3 are detachably mounted on the head-mounted bracket 1 via their respective mounting portions 31. Users can install or remove the lighting units 3 according to their needs. While ensuring that the surgical headlight 100 provides good lighting effects, the weight of the surgical headlight 100 can also be adaptively adjusted to reduce unnecessary loads, lower the overall weight of the surgical headlight 100, and improve wearing comfort. For example, in applications where fill light requirements are low, users can remove lighting units 3 that are not required for lighting.

[0031] The light from multiple lighting units 3 shines into the operating area from different positions and angles, reducing or eliminating blind spots and shadowed areas, providing the user with excellent lighting effects. The drive device 2 is connected to the lighting unit 32 of at least one lighting unit 3 to drive the lighting unit 32 to adjust the position or angle of the light emitted by the lighting unit 32. This allows for more precise adjustment of the lighting area, enabling collaboration with other lighting units 3 to achieve a shadowless lighting area. Compared to solutions where the user manually adjusts the light, the drive device 2 can drive the lighting unit 32 to adjust the lighting position through voice control, wireless remote control, or automatic control, without requiring the user to physically touch the surgical headlight 100 for adjustment. This avoids compromising the sterility of the surgical procedure and improves the safety of the procedure.

[0032] Through the above-described technical solution, the surgical headlight 100 provided in the disclosed embodiment can be worn on the user's head and provide illumination. The user can install or remove some of the lighting units 3 according to their needs, adaptively adjusting the weight of the surgical headlight 100 to improve wearing comfort. Light from multiple lighting units 3 illuminates the operating area from different positions and angles, reducing or eliminating blind spots and shadowed areas, providing the user with excellent lighting effects. The drive device 2 can actively drive the illumination components 32 of the lighting units 3, enabling more precise adjustment of the illuminated area to achieve shadowless operation. This adjustment process eliminates the need for manual intervention by the user, preventing compromise of surgical sterility and improving safety.

[0033] In the embodiment of the present disclosure, the shape of the head-mounted bracket 1 can be adjusted as needed. For example, the head-mounted bracket 1 can include an annular fixing portion and a top-of-the-head fixing portion. The annular fixing portion can be used to surround the circumference of the user's head, while the top-of-the-head fixing portion can fit the top of the user's head, and together they play a good fixing role. The size of the head-mounted bracket 1 can be set to be adjustable. For example, the annular fixing portion can have an elastic telescopic section, or one end of the annular fixing portion can be set as an inserting section, and the other end can be provided with a connector. The user can adjust the circumferential size of the annular fixing portion by inserting different positions of the inserting section of the annular fixing portion into the connector, so that the annular fixing portion can match the user's head circumference, thereby improving the wearing stability and comfort of the head-mounted bracket 1.

[0034] In addition, the head-mounted bracket 1 can be made of one or more materials such as nylon, metal or carbon fiber. Optionally, the head-mounted bracket 1 can be made of carbon fiber material to ensure that the head-mounted bracket 1 has good strength while reducing the overall weight of the head-mounted bracket 1 to provide wearing stability and comfort.

[0035] The mounting portion 31 of the lighting unit 3 can be detachably mounted on the head-mounted bracket 1 by means of screw connection or snap connection. In an exemplary embodiment, a mounting hole can be formed on the mounting portion 31 of the lighting unit 3, and a plurality of screw holes can be formed on the head-mounted bracket 1. The fastening bolt can be passed through any screw hole on the mounting portion 31 of the lighting unit 3 and the head-mounted bracket 1 to achieve the connection between the lighting unit 3 and the head-mounted bracket 1.

[0036] In another exemplary embodiment, the head mount 1 optionally includes multiple snap-in sockets 11, and the mounting portion 31 of the lighting unit 3 is formed as a snap-in plug 311. The lighting unit 3 is removably connected to any snap-in socket 11 on the head mount 1 via the snap-in plug 311. In this embodiment, the snap-in socket 11 can be formed as a slot with an upward opening, and the snap-in plug 311 can be formed as a U-shaped structure with a downward opening. Due to the inherent weight of the lighting unit 3, the snap-in plug 311 can be stably inserted into the snap-in socket 11. Alternatively, the snap-in socket 11 can be formed as a female buckle with an elastic portion, and the snap-in plug 311 can have a retaining groove. The snap-in plug 311 overcomes the elastic action of the elastic portion to be inserted into the snap-in socket 11. The elastic portion engages with the retaining groove under the elastic action, thereby securing the snap-in plug 311 in the snap-in socket 11. During the disassembly process, the user can apply a disassembly force to the snap-in plug 311, or apply a disassembly force to the elastic portion to release the elastic portion from the retaining groove. Thus, the snap-in plug 311 and the snap-in socket 11 can be detachably connected using a variety of structures, and this disclosure does not limit the specific structure.

[0037] In the above embodiment, a plurality of snap-in sockets 11 are formed on the head-mounted bracket 1, and the lighting unit 3 can be detachably plugged into any snap-in socket 11 on the head-mounted bracket 1 through a snap-in plug 311. The user can selectively plug the lighting unit 3 into the snap-in sockets 11 at different positions on the head-mounted bracket 1 according to lighting requirements, and can flexibly adjust the lighting area, while also adjusting the comfort and balance of the head-mounted bracket 1.

[0038] The lighting unit 3 provided in the embodiment of the present disclosure may be an independent light source, such as an LED lamp head 321. Alternatively, the lighting unit 3 may serve only as a light emitting structure. For example, the lighting unit 32 may be connected to an optical fiber that guides a light beam into the lighting unit 32 and emits the light beam through the lighting unit 32.

[0039] In an embodiment where the lighting portion 32 is an LED lamp head 321, the LED lamp head 321 needs to be powered to emit light. Based on this, a battery corresponding to the LED lamp head 321 can be provided in the lighting unit 3, or the surgical headlight 100 can be provided with a power supply, and the LED lamp heads 321 of multiple lighting units 3 can all be connected to the power supply.

[0040] In conjunction with the embodiment in which the mounting portion 31 is a snap-on plug 311, the surgical headlight 100 may optionally further include a power supply. The lighting portion 32 is an LED lamp holder 321. A first conductive portion is disposed within the snap-on socket 11 and is electrically connected to the power supply. The snap-on plug 311 is provided with a second conductive portion. When the snap-on plug 311 is inserted into the snap-on socket 11, the second conductive portion comes into electrical contact with the first conductive portion. Specifically, when the lighting unit 3 is inserted into the snap-on socket 11 of the headgear 1 via the snap-on plug 311, the lighting unit 3 is securely mounted to the headgear 1, while the LED lamp holder 321 is electrically connected to the power supply, thereby providing power to the lighting unit 3. In this embodiment, each lighting unit 3 does not require a separate power supply, which streamlines the structure of the surgical headlight 100, reduces its overall weight, and further improves its wearing comfort. The power supply here can be installed on the head-mounted bracket 1, or can be set separately from the head-mounted bracket 1. For example, the power supply can be worn on other parts of the user through structures such as a strap.

[0041] In embodiments where the illumination unit 32 is connected to an optical fiber, the illumination unit 3 does not require a power supply or light source. The illumination unit 32 serves solely as a light-emitting structure, significantly reducing the structural complexity and weight of the illumination unit 3 and improving the wearing comfort of the surgical headlight 100. Furthermore, in medical or specialized laboratory environments, the illumination unit 3, through optical fiber, is not affected by electromagnetic shielding, making it suitable for a wider range of applications.

[0042] In conjunction with the embodiment in which the mounting portion 31 is a snap-on plug 311, the surgical headlight 100 can optionally include a light source device and multiple optical fibers. The light inlet ends of the optical fibers are connected to the light source device, and the light outlet ends of the optical fibers are located within the snap-on socket 11. The snap-on plug 311 is formed with a light inlet that communicates with the illumination unit 32. When the plug is plugged into the snap-on socket 11, the light outlet ends of the optical fibers mate with the light inlet of the illumination unit 32. The optical fibers guide light from the light source device into the illumination unit 32, where it is then emitted outward to the illuminated area. In this embodiment, the illumination unit 32 serves solely as a light-emitting structure. For example, the illumination unit 32 may include light-processing structures such as a focusing lens or a uniform light lens, significantly reducing the structural complexity and weight of the illumination unit 32. Multiple illumination units 3 can be connected to the same light source device via optical fibers, allowing for greater flexibility in the placement of the light source device. For example, the light source device can be mounted on the headband 1, worn elsewhere on the user via a strap, or even placed externally without the user wearing the device. It can be seen that the surgical headlight 100 in this embodiment has a more flexible arrangement, which is conducive to adapting to different application scenarios and improving the user experience.

[0043] The driving device 2 is connected to the lighting part 32 of at least one lighting unit 3 to drive the lighting part 32 to move, thereby changing the position of the light spot emitted by the lighting part 32. Optionally, the driving device 2 may include a micromotor 21. In this embodiment, the micromotor 21 may be integrated with the lighting unit 3, or the micromotor 21 may be detachably mounted on the head-mounted bracket 1. The micromotor 21 may be selected according to the movement mode of the lighting part 32. Taking the example in which the lighting part 32 is rotatably connected to the mounting part 31 via a universal joint rotating seat, the micromotor 21 here may be a rotary motor, and the output shaft of the rotary motor is connected to the universal joint rotating seat to drive the universal joint rotating seat to rotate. In the embodiment in which the lighting part 32 is movably connected to the mounting part 31 via a telescopic rod, the micromotor 21 may be a linear motor. It can be seen that those skilled in the art can realize that the driving device 2 drives the lighting part 32 to move according to relevant technologies, and the present disclosure does not limit its specific structure.

[0044] In an exemplary embodiment, the driving device 2 can be optionally mounted on the head-mounted bracket 1. The driving device 2 includes a driving member and a plurality of traction wires connected to the driving member. The plurality of traction wires are arranged in a one-to-one correspondence with the plurality of lighting units 3. One end of the traction wire is connected to the driving member, and the other end of the traction wire is connected to the lighting portion 32 of the lighting unit 3. Taking the lighting portion 32 as an example in which the lighting portion 32 is rotatably connected to the mounting portion 31 via a universal joint rotating seat, the traction wire here can be wound around the universal joint rotating seat, and the driving member can drive the universal joint rotating seat to rotate by driving the traction wire to move. Alternatively, the traction wire can be connected to a rack structure, and the rack structure cooperates with the universal joint rotating seat through a gear. In the embodiment in which the lighting portion 32 is movably connected to the mounting portion 31 via a telescopic rod, the traction wire can be connected to the telescopic rod, and the driving member can drive the telescopic rod to extend or shorten by driving the traction wire to move.

[0045] The number of lighting units 3 can be selected according to the needs of the application scenario. As shown in Figure 2, optionally, the multiple lighting units 3 can include at least two front lighting units 33 and at least two side lighting units 34. The at least two front lighting units 33 are arranged at intervals in the up and down directions, and the at least two side lighting units 34 are respectively located on both sides of the head-mounted bracket 1 in the left and right directions. In this embodiment, the two front lighting units 33 can be located in the user's nose bridge area. The two front lighting units 33 provide forward direct light to the operating area, eliminating the forward lighting blind spot and improving the brightness of the operating area. The two side lighting units 34 can be located on both sides of the user's face, respectively. The two side lighting units 34 provide side light from the side, eliminating the lighting blind spot on the left and right sides. It can be seen that by cooperating with at least two front lighting units 33 and at least two side lighting units 34, a shadowless lighting area can be achieved.

[0046] When the lighting unit 3 emits light, the position, size, and brightness of the light spot emitted by the lighting unit 32 will affect the lighting quality. The position of the light spot emitted by the lighting unit 32 can be adjusted by driving the position of the lighting unit 32 by the driving device 2. The size and brightness of the light spot emitted by the lighting unit 32 can also be adjusted. In the embodiment where the lighting unit 32 is an LED lamp head 321, the size and brightness of the light spot emitted by the LED lamp head 321 can be adjusted by adjusting the pulse width or current size of the current passing through the LED lamp head 321. In the embodiment where the lighting unit 32 is connected to the light source device through an optical fiber, the size and brightness of the light spot emitted by the lighting unit 32 can be adjusted by adjusting the output light parameters of the light source device or by adjusting the position of the lens in the lighting unit 32. It can be seen that the position, size, and brightness of the light spot emitted by the lighting unit 32 can be adjusted by those skilled in the art according to relevant technologies, and this disclosure does not impose specific restrictions on this.

[0047] In order to facilitate the doctor to adjust the lighting unit 3 during the operation, the surgical headlight 100 may optionally include a control device 4, and the control device 4 may include a voice receiver 41 and a controller 42. The voice receiver 41 is used to receive the user's voice instructions, and the controller 42 is electrically connected to the voice receiver 41, the drive device 2 and the lighting unit 3 respectively. The controller 42 is used to control the control device 4 and / or the lighting unit 3 according to the voice instructions received by the voice controller 42, so as to at least adjust one or more of the position, size and brightness of the light spot emitted by the lighting part 32.

[0048] In the above embodiment, while performing surgery using surgical headlight 100, a surgeon can adjust the light spot of the illuminated area via voice commands. For example, when voice receiver 41 receives a user's voice command to adjust the light spot position, controller 42 controls control device 4 based on the voice command, thereby adjusting the position of illumination unit 32 and achieving the desired light spot position. During voice control, the surgeon can adjust the light spot parameters emitted by illumination unit 3 without touching surgical headlight 100. This convenient and quick process ensures the sterility of the medical procedure.

[0049] Optionally, the surgical headlight 100 also includes a camera device 5 detachably mounted to the head mount 1. The camera device 5 includes a periscope camera 51. The periscope camera 51 is also referred to as an internal zoom camera, meaning that optical zoom is performed internally within the camera body, and the external dimensions of the camera device 5 do not change during zooming. The camera device 5 can be located on the surgeon's forehead, in front of the surgeon's nose, or on the top or side of the surgeon's head. This disclosure does not limit the specific location of the camera device 5. For example, as shown in FIG1 , the lens assembly 511 of the camera device 5 is disposed within a longitudinally extending sleeve 512. The longitudinal direction here refers to the longitudinal direction of the surgical headlight 100 when worn, i.e., the up-down direction. The lens assembly 511 is disposed within the longitudinally extending sleeve 512 to facilitate placement of the lens assembly 511 of the periscope camera 51 and prevent it from obstructing the view. The sleeve 512 here can also have a wearing function, that is, the sleeve 512 can be used to abut against the user's head or face to provide support for the surgical headlight 100, so that the surgical headlight 100 can be stably worn on the user's head.

[0050] In the above embodiment, the camera device 5 on the surgical headlight 100 can film the surgical process, which is convenient for the doctor to record the surgical process as a basis for surgical archiving, review and research. The camera device 5 can also provide live broadcast of the surgery, which is used in scenarios such as multi-doctor remote collaborative surgery and has a wide range of applications. Optionally, the effective working distance of the camera device 5 can be 25cm-60cm to ensure effective shooting. Optionally, the field of view diameter of the camera device 5 can be less than 30cm, so that the shooting range of the camera device 5 is concentrated on the surgical area. In other embodiments, the camera device 5 can have a wide-angle lens.

[0051] Parameters such as the field of view, depth of field, focal length, white balance, image size, and high dynamic range of the camera device 5 can be adjusted. For example, the camera device 5 has a camera control board inside, and the camera control board can control the automatic adjustment or processing of the camera parameters. Those skilled in the art can implement this according to relevant technologies, and this disclosure will not elaborate on this. Optionally, the surgical headlight 100 includes a control device 4, and the control device 4 includes a voice receiver 41 and a controller 42. The voice receiver 41 is used to receive the user's voice instructions. The controller 42 is electrically connected to the voice receiver 41 and the camera device 5 respectively. The controller 42 is used to control the camera device 5 according to the voice instructions received by the voice controller 42 to at least adjust one or more of the field of view, depth of field, focal length, white balance, image size, and high dynamic range of the camera device 5.

[0052] As shown in FIG1 , optionally, the surgical headlight 100 may further include an AR display device 6, which is detachably mounted on the head-mounted bracket 1, and is electrically connected to the camera device 5. The AR display device 6 here may be AR glasses or an AR display screen, etc. The AR display device 6 is electrically connected to the camera device 5, and can display the content captured by the camera device 5 for the doctor to view. Alternatively, the AR display device 6 may also have a wireless communication function, or may be connected to a database to display other content, for example, it may display the patient's medical history, imaging pictures, or real-time vital signs parameters to provide a reference for the doctor's surgical process.

[0053] Optionally, the surgical headlight 100 includes a control device 4, which includes a voice receiver 41 and a controller 42. The voice receiver 41 is used to receive voice commands from the user, and the controller 42 is electrically connected to the voice receiver 41 and the camera device 5 respectively. The controller 42 is used to control the AR display device 6 according to the voice commands received by the voice controller 42, so as to adjust at least one or more of the display content, screen size and color parameters of the AR display device 6.

[0054] As an exemplary application scenario, a doctor can use voice commands to control the AR display device 6 to enlarge the size of the displayed content, thereby viewing image details in greater detail. The voice receiver 41 receives the user's voice command, and the controller 42 controls the AR display device 6 to adjust the size of the enlarged displayed content according to the voice command received by the voice controller 42.

[0055] In some embodiments, surgical headlight 100 may include a pupil tracking sensor for tracking the position of the user's pupils. The specific structure of the pupil tracking sensor can be implemented using related technologies and is not limited by this disclosure. Control device 4 includes controller 42, which is electrically connected to the pupil tracking sensor, drive device 2, camera device 5, and AR display device 6.

[0056] In the above embodiment, the controller 42 can be used to control the position of the light spot emitted by the lighting unit 3 based on the pupil position information. For example, the controller 42 can control the position of the light spot emitted by the lighting unit 3 to follow the position of the pupil based on the pupil position information, thereby flexibly adjusting the area illuminated by the light spot and realizing intelligent surgical procedures.

[0057] In some embodiments, the controller 42 can be used to control the focus position of the camera device 5 according to the pupil position information, thereby intelligently adjusting the camera quality of the camera device 5.
