Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, specifically relating to an operating room shadowless lamp lighting device with multiple environmental lamp modules to adapt to different lighting needs in different working areas of the operating room. Background Technology

[0002] Operating lights are essential lighting devices commonly used in medical environments such as operating rooms and emergency rooms. In open surgery, they provide surgeons with consistently high-intensity, focused main illumination within their field of vision to meet the brightness and uniformity requirements of open surgical procedures. With advancements in lighting technology, ambient lighting is increasingly being incorporated into operating room lighting systems. By using different lighting methods, such as warm or cool light, different atmospheres are created, improving the operating room environment and enhancing staff comfort to a certain extent. However, in practice, the lighting requirements for different work areas within the operating room, such as the surgeon's area, the display screen area, the anesthesia area, and the handwashing area, are not the same. The surgeon's area generally requires high-intensity lighting, which can be achieved using shadowless lamps. However, with the development of medical technology, minimally invasive laparoscopic surgery has become widespread, accounting for over 80% of surgeries. During laparoscopic surgery, high-intensity lighting is usually no longer needed, so the operating room shadowless lamps and ambient lights are mostly turned off. Currently, in minimally invasive laparoscopy, surgeons typically turn off the shadowless lamps and ambient lights, performing surgery in darkness by observing images on a medical display screen. This makes it difficult to see the images clearly, and prolonged surgery can cause significant damage to the surgeon's eyesight. Turning on the ambient lights would create glare, affecting the surgeon's ability to properly observe the display screen, thus impacting the safety and efficiency of the surgery. Turning off the ambient lights could affect the work and performance of scrub nurses, circulating nurses, and anesthesiologists in other work areas.

[0003] Furthermore, the requirements for ambient lighting vary at different stages of the surgical procedure, such as when the patient enters the operating room, during the surgery, after the surgery, and during the operating room cleaning process. During surgical preparation, interoperative pauses, postoperative cleaning, and personnel movement, the operating room still needs soft, non-intrusive ambient lighting to assist medical staff in observing instruments and the surrounding environment, and to improve comfort and safety.

[0004] Traditional, single-function surgical shadowless lamps are no longer adequate for the lighting needs of modern surgery. In conventional medical lighting systems, shadowless lamps and ambient lights are typically controlled and operated separately, which is inconvenient and lacks design for different work areas. Some surgical shadowless lamp products include simple ambient light modules, mostly providing green or cool white light illumination using monochromatic low-brightness LEDs, primarily located inside the front glass cover of the shadowless lamp. However, these designs are not conducive to creating a large-area light curtain, resulting in limited effectiveness in creating a visual lighting environment. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes an operating room shadowless lamp lighting device. It utilizes the available space such as the dome or other external structures on the back of the operating shadowless lamp to add distributed ambient light modules and set up corresponding diffuser covers to form a uniform and soft surrounding light curtain, achieving a non-direct and visually comfortable lighting effect.

[0012] Preferably, the main body of the shadowless lamp is a disc-shaped structure, the first ambient lamp cover is a hemispherical structure, the second ambient lamp cover is an arc-shaped frosted lamp cover, and the third ambient lamp cover is a cylindrical or lantern-shaped structure.

[0013] Preferably, the device includes a light source control circuit, which is electrically connected to the shadowless lamp light source, the first ambient lamp module, the second ambient lamp module, and the third ambient lamp module.

[0014] Preferably, a connecting seat is provided on the side wall of the main body of the shadowless lamp, and the operating room shadowless lamp lighting device further includes a connecting component, which includes a support, a central column, a rotating arm and several connecting arms; The central column is fixed on the support, one end of the rotating arm is mounted on the central column by a first rotating connector, and the other end is provided with a second rotating connector; The two ends of the connecting arm are respectively provided with a third rotating connector and a fourth rotating connector.

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Example 1 like Figures 1 to 9 As shown, this embodiment proposes an operating room shadowless lamp lighting device, including a disc-shaped shadowless lamp body 1. A shadowless lamp light source 2 and a shadowless lamp cover 3 are arranged on the front of the shadowless lamp body 1. A first ambient light module 4 and a first ambient light cover 5 are arranged at the center of the back of the shadowless lamp body 1. Multiple second ambient light modules 6 and second ambient light covers 7 are arranged circumferentially along the edge of the shadowless lamp body 1. A light-shielding member 8 is arranged between adjacent second ambient light modules 6. The light-shielding member 8 can be part of the shadowless lamp body 1 or the shadowless lamp cover 3.

[0025] A mounting base 12 is provided at the center of the front of the shadowless lamp body 1. The mounting base 12 is used to detachably mount the handle 9 or the third ambient light cover as needed. The third ambient light cover contains a third ambient light module 11, and the third ambient light cover has the same external structure as the handle. The connection between the mounting base 12 and the handle 9 / third ambient light cover can be a threaded connection, a snap-fit ​​connection, or other common connection structures. For example, a threaded mounting hole is provided at the center of the mounting base 12, and the handle 9 / third ambient light cover is provided with an external threaded connection part that matches the threaded mounting hole. Alternatively, a slot is provided on the mounting base 12, and a snap-fit ​​part that matches the slot is provided on the outer wall of the handle 9 / third ambient light cover.

[0026] The device is equipped with a light source control circuit 10. The light source control circuit 10 is electrically connected to the shadowless lamp light source 2, the first ambient lamp module 4, the second ambient lamp module 6 and the third ambient lamp module 11. The installation position of the light source control circuit 10 is not limited and can be selected according to specific needs.

[0027] The operating room shadowless lamp lighting device designed in this embodiment includes a first ambient light module 4, a second ambient light module 6, and a third ambient light module 11, each comprising several light strips. Each light strip is equipped with multiple RGB tri-color LEDs. The light strips of the first ambient light module 4 are symmetrically arranged on the back of the shadowless lamp body 1; the light strips of the second ambient light module 6 are arranged circumferentially along the edge of the shadowless lamp body 1; and the light strips of the third ambient light module 11 are arranged axially along the third ambient light cover. Each light strip includes multiple RGB tri-color LEDs arranged in a distributed manner. This allows for arbitrary color adjustment of the RGB tri-color LEDs. By adjusting the brightness of red, green, and blue, the desired color of light can be generated, such as producing red light, green light, cool white light, and warm white light, among other color temperature ambient lighting.

[0028] The shape of the light strip in the first ambient light module 4 can be any one of ring, arc or rectangle. Figure 3 Example 1 shown includes a first annular light strip 41 with an annular structure; Figure 4 Example 2 shown includes a second annular light strip 42 and a third annular light strip 43 arranged concentrically; Figure 5 Example 3 shown includes nine rounded rectangular light strips 44 evenly spaced around the main body of the shadowless lamp 1; Figure 6 Example 4 shown includes four arc-shaped light strips 45 symmetrically arranged around the central axis of the main body 1 of the shadowless lamp. The position, shape, and number of the light strips can be adjusted to meet the illumination requirements of different working positions.

[0029] Figure 1 The second ambient light module 6 shown includes an upper light strip 61, a side light strip 62 and a lower light strip 63, which are respectively installed on the back edge, side edge and front edge of the shadowless lamp body 1, and each light strip is provided with at least one row of LEDs.

[0030] In this embodiment, the device includes a connecting assembly, which allows the device to be mounted on the ceiling of the operating room, a mobile support, or other types of mounting structures. For example... Figure 10 and Figure 11In the example shown, the connecting assembly includes a support 100, a central column 101, three rotating arms 102, a first connecting arm 103, a second connecting arm 104, and a third connecting arm 105. The central column 101 is fixed to the support 100. The central column 101 is provided with several 360-degree rotatable rotating arms 102. One end of each rotating arm 102 is fitted onto the central column 101 via a first rotating connector 1021, and the other end is provided with a second rotating connector 1022.

[0031] The first connecting arm 103, the second connecting arm 104, and the third connecting arm 105 are respectively provided with a third rotating connector 1041 and a fourth rotating connector 1042 at both ends. One end of the first connecting arm 103 is connected to the second rotating connector 1022 via the third rotating connector 1041, and the other end is connected to the third rotating connector 1041 at one end of the second connecting arm 104 via the fourth rotating connector 1042. In this way, the first connecting arm 103, the second connecting arm 104, and the third connecting arm 105 are connected end-to-end. The fourth rotating connector 1042 on the last third connecting arm 105 is mated with the connecting seat 13 on the side wall of the shadowless lamp body 1, realizing the rotational adjustment of the shadowless lamp body 1 in multiple directions. The connecting arms are spring arms, which are hollow inside and equipped with spring assemblies, providing strong load-bearing capacity. Each rotating connector can be selected from conventional connection structures in the prior art, such as rotating connecting shafts / sleeves, pins, rotating pairs, or cam mechanisms.

[0032] In this embodiment, the rotating arm 102 rotates 360 degrees horizontally around the axis of the central column 101. Several rotating arms 102 can be designed with different lengths to facilitate extension to different working areas of the operating room. Multiple spring arms form a linkage structure connecting the rotating arm 102 and the shadowless lamp body 1. This linkage structure allows adjustment of the vertical height and tilt angle of the shadowless lamp body.

[0033] The operating room shadowless lamp lighting device designed in this utility model is installed on a connecting assembly. The rotating arm and connecting arm in the connecting assembly are then adjusted so that the corresponding light modules are aligned with the target area. For example, by adjustment, the light radiation area of ​​the shadowless lamp light source 2 and the third ambient light module 11 includes the surgeon's area inside the operating room; the light radiation area of ​​the first ambient light module 4 includes the display screen area and the assistant area; and the light radiation area of ​​the second ambient light module 6 includes the anesthesia area and the handwashing area. Furthermore, multiple operating room shadowless lamp lighting devices of this design can be combined. By superimposing the green or red light emitted by multiple devices, an unsaturated and glare-free green or red light can be formed.

[0034] This invention features a first ambient light module 4 placed on the back shell of the surgical shadowless lamp, enabling multi-color variable ambient lighting. Furthermore, the color temperature and illuminance of the light can be adjusted based on the relative position of the surgical lamp and the monitor. Specifically, a position sensor is installed on the main body 1 of the shadowless lamp and its control device to sense the relative direction and distance between the monitor and the lamp body, thereby automatically or manually adjusting the color and brightness of light emitted from different areas to provide the most suitable visual lighting environment for different work areas (such as the surgeon's area, the display screen area, the anesthesia area, and the handwashing area). The first ambient light cover 5 can be configured to share a hemispherical shell structure with the main surgical lamp system, i.e., the shadowless lamp system, enabling modular assembly and facilitating installation and maintenance.

[0035] The second ambient light housing 7 adopts an arc-shaped frosted light cover, and all the second ambient light housings 7 form a circular structure. This fully utilizes the dome or other external structures and available space on the back of the surgical shadowless lamp, and through its hemispherical outer shell and diffuser, forms a uniform and soft surrounding light curtain, effectively achieving a non-direct and visually comfortable lighting effect. Figure 8 As shown, the second ambient light module 6 emits red and green light, which can form unsaturated red or unsaturated green light by superimposing the light emitted by multiple devices, and there is no glare. This allows surgeons to see the screen more clearly during minimally invasive laparoscopic surgery and avoid visual fatigue during long-term surgery.

[0036] This invention utilizes the detachable handle 9 of a surgical shadowless lamp, replacing it with a third ambient light cover and its module 11 during minimally invasive laparoscopic surgery. The cylindrical or lantern-shaped lamp post and diffuser create a uniform and soft, surrounding light curtain, effectively achieving a non-direct and visually comfortable lighting effect. This design meets the needs of minimally invasive laparoscopic surgery without requiring additional equipment.

[0037] This invention embeds an ambient lighting module into the non-primary light-emitting surface of the surgical light housing, such as the top, back, or sides, using a semi-circular diffuser design to create a surrounding, uniform, and glare-free background lighting effect. The device integrates sensors to automatically adjust the ambient color temperature and illuminance of different areas based on the relative positions of the surgical light, display screen, or operators, to avoid glare and reflections while meeting the visual needs of each member of the surgical team. The control system can also be implemented through an external interface, such as a touchscreen, panel buttons, foot pedal, or voice control, to switch ambient light modes and adjust the brightness and color temperature of the light source. This significantly improves the illuminance of the minimally invasive laparoscopic surgical environment, enhancing the concentration of medical staff. The multi-color ambient lighting also helps reduce eye fatigue and improves the working environment.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
