Description

Technical Field

[0001] The utility model relates to the field of plastic surgery, and more particularly to an improved headlamp for plastic surgery. Background Art

[0002] In the field of plastic surgery, the lighting conditions during surgery have a crucial impact on the doctor's operating accuracy and surgical results. Although the traditional operating room lighting system has met the basic needs of surgery to a certain extent, its limitations have gradually become apparent, such as light source scattering, heat generation, and poor adjustability. These problems have posed many challenges to doctors during surgery. Therefore, plastic surgery headlights have emerged as a new type of lighting equipment, continuously improving surgical conditions with their excellent performance and unique advantages.

[0003] In traditional operating room lighting systems, surgical lights are usually fixed to the ceiling or wall of the operating room. This fixed lighting method has the following limitations:

[0004] Light source scattering: The light source of traditional surgical lamps is often scattered, making it difficult to focus the light on the surgical area. As a result, doctors need to constantly adjust the angle and height of the surgical lamp during the operation to obtain the best lighting effect.

[0005] Heat generation: Traditional surgical lights release a lot of heat while lighting, which may cause the temperature of the surgical area to rise, thus affecting the surgical effect and patient comfort.

[0006] Poor adjustability: Traditional surgical lights have limited adjustability, making it difficult for doctors to quickly adjust the brightness, color temperature, and angle of the light according to surgical needs.

[0007] In response to the limitations of traditional lighting systems, plastic surgery headlights have emerged. Their advantages are mainly reflected in the following aspects:

[0008] Plastic surgery headlamps typically utilize high-brightness LEDs, providing a more uniform, clearer beam. This high-intensity illumination makes subtle anatomical structures more clearly discernible, improving surgical safety and success rates. Plastic surgery headlamps also generate less heat during illumination, helping maintain a stable surgical environment and reducing discomfort for both patients and surgeons. LED lamps have a lifespan far exceeding that of traditional bulbs, eliminating the need for frequent light replacements. Furthermore, LED light sources consume less energy, helping to reduce operating room operating costs.

[0009] Chinese patent application document 1 (application number: 202021401327.7, application date: 2020.07.16) discloses a headlamp for plastic surgery, referring to Figure 1, comprising a first curved plate 01, a second curved plate 02 is provided on one side of the first curved plate 01, and a first telescopic element 04 and a second telescopic element 03 are provided between the first curved plate 01 and the second curved plate 02, so that the doctor can wear the device on his head. However, the device is prone to loosening and falling off during actual use. When the device reaches a certain service life, the first telescopic element 04 and the second telescopic element 03 are easily damaged, resulting in poor stability.

[0010] Chinese patent application document 2 (application number: 202022956287.9, filing date: 2020.12.09) discloses a headlamp for plastic surgery, comprising an elastic band, a lamp head, an arc-shaped hoop plate, a storage box, a transverse arc-shaped top plate, a longitudinal arc-shaped top plate, and a control assembly. When in use, the elastic band is fixed to the head, and the transverse arc-shaped top plate and the longitudinal arc-shaped top plate are cross-reinforced, resulting in poor comfort during use. Furthermore, the elastic force of the elastic band is limited, and it is prone to rebound. This results in poor comfort and poor fixation for users with larger head circumferences.

[0011] Chinese patent application document 3 (application number: 201821204837.8, application date: 2018.07.27) discloses a headlamp for plastic surgery. By setting a front clip plate, a movable rod, a spring and a clip block and other structures, the front clip plate is fixed inside the storage box by using the automatic rebound of the spring, thereby allowing the staff to adjust and fix the headlamp according to their own head circumference. During use, the headband is adjusted by the spring. After repeated use, the spring is prone to jamming, and the comfort and stability of use are poor.

[0012] Chinese patent application document 4 (application number: 202122599394.5, application date: 2021.10.28) discloses a headlamp for plastic surgery. By setting a cleaning device on the headband, starting the motor, and the output end of the motor drives the fixed rod to rotate, the cleaning cloth on the fixed rod rotates. At this time, the rotating cleaning cloth absorbs the fog on the lens and wipes the lens to ensure the cleanliness of the headlamp. A sponge cover is set inside the headband. When the doctor wears the headband for surgery, the sweat on the head will flow to the sponge cover and be absorbed by the sponge cover, which is different from the problem solved by this application.

[0013] Therefore, it is very necessary to provide an improved plastic surgery headlamp with strong fixation, stability and comfort. Utility Model Content
