[0033] Shadowless lamps are primarily used in hospital operating rooms, emergency rooms, and radiology departments. They produce images by emitting X-rays, helping doctors observe the patient's internal structures and organs, assisting with surgical procedures and diagnoses. However, during laparoscopic surgery, the doctor must remain within the body cavity, limiting the lighting effectiveness of the shadowless lamp, thus impacting the safe conduct of the procedure. Laparoscopic lamps are often integrated into shadowless lamps and used together. Laparoscopic lamps can create a light spot within the surgical area or body cavity, complementing the illumination provided by the shadowless lamp.

[0034] Existing laparoscopic lights are a combination of a ring light bar and a diffuser plate. The ring light bar is equipped with multiple LEDs. The light generated by the LEDs is diffused by the diffuser plate, providing a spot of light that can illuminate the operating table area during surgery. However, the ring light bar has multiple LEDs, which is expensive, and the diffuser plate only disperses the light, failing to form a distinct and uniform spot, which is detrimental to the smooth progress of laparoscopic surgery. In addition, existing laparoscopic lights do not have an adjustable multi-color mixed spot for auxiliary lighting.

[0035] Based on this, Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a laparoscope lamp for surgery, comprising an LED lamp bead 1 and a lens 2. The LED lamp bead 1 is used to output light of different colors; the lens 2 is in the shape of a truncated cone with an arc-shaped sidewall, with the two ends of the lens 2 being a light input end and a light output end, respectively, and the diameter of the light input end is smaller than the diameter of the light output end. The LED lamp bead 1 is arranged on one side of the light input end of the lens 2; wherein, the light output end of the lens 2 is evenly and densely distributed with a plurality of bead surfaces 21. The colored light generated by the LED lamp bead 1 is projected and reflected inside the lens 2, and then output from the light output end of the lens 2 to form a circular and uniform light spot.

[0036] The laparoscope lamp used for surgery disclosed herein has a plurality of bead surfaces 21 evenly and densely distributed on the light output end of the lens 2. The colored light generated by the LED lamp bead 1 is projected and reflected inside the lens 2 and then output from the light output end of the lens 2. After being reflected by the plurality of bead surfaces 21, a uniform light spot can be formed. During the laparoscope surgery, the surgical area can be illuminated more clearly, which is beneficial to improving the safety of the surgery.

[0037] The following is a detailed description of various parts of a laparoscope lamp for surgery provided by an embodiment of the present disclosure with reference to the accompanying drawings:

[0038] In the embodiment disclosed herein, the laparoscope lamp includes an LED lamp bead 1 and a lens 2. The LED lamp bead 1 is used to output colored light of different colors. The lens 2 is truncated cone-shaped and its side wall is an arc-shaped surface convex to the outside. The two ends of the lens 2 are respectively the light input end and the light output end, and the diameter of one end of the light input end of the lens 2 is smaller than the diameter of one end of the light output end. The LED lamp bead 1 is arranged on one side of the light input end of the lens 2. The colored light generated by the LED lamp bead 1 is irradiated into the interior of the lens 2 from the light input end of the lens 2. The side wall of the lens 2 with an arc-shaped surface can project and reflect the light irradiated into the interior of the lens 2, and then the light is output from the light output end of the lens 2. Since the end face of the light output end of the lens 2 is evenly and densely distributed with a number of bead surfaces 21, that is, the end face of the light output surface of the lens 2 is composed of a plurality of convex hemispherical surfaces. The light projected and reflected from the interior of the lens 2 is output from the light output surface of the lens 2, forming a circular and uniform light spot.

[0039] In one embodiment of the present disclosure, three LED lamp beads 1 are provided, three lenses 2 are provided, and one LED lamp bead 1 and one lens 2 form a group of laparoscope lamp units; wherein, the three groups of laparoscope lamp units are arranged in an equilateral triangle shape to form a laparoscope lamp for surgery, and the three LED lamp beads 1 can respectively generate red, green and blue colors of light.

[0040] It is understandable that the three groups of laparoscope lamp units are arranged in an equilateral triangle shape and can be tilted toward the midpoint of the equilateral triangle. When the three groups of laparoscope lamp units are all turned on, the light spots formed by the three groups of laparoscope lamp units can form a circular and uniform light spot.

[0041] At the same time, the three LED lamp beads 1 can generate red, green, and blue colors respectively. By individually controlling the on and off of the three LED lamp beads 1, a multi-color mixed light spot can be formed, which is conducive to improving the practical effect of the laparoscope lamp. In addition, the illumination intensity of the three LED lamp beads 1 can be adjusted, thereby achieving the adjustment of the size and brightness of the light spot formed by the laparoscope lamp, which is convenient for use during surgery.

[0042] It is understandable that by combining the LED lamp bead 1 with the lens 2, the light generated by the LED lamp bead 1 can be focused and controlled, thereby producing the desired light characteristics. Three LED lamp beads 1 and three lenses 2 are used, corresponding to the three colors of red, green and blue light respectively. By controlling the operating current and voltage of the LED lamp bead 1, it can emit light of different wavelengths, thereby producing light of different colors. The lens 2 can focus and disperse the light emitted by the LED lamp bead 1, thereby changing the propagation direction and angle of the light. Factors such as the shape, material and surface treatment of the lens 2 will affect the focusing effect of the light. In this embodiment, the lens 2 is in the shape of a truncated cone with an arc-shaped side wall, and the three lenses 2 are arranged in an equilateral triangle shape to achieve more uniform and concentrated lighting.

[0043] By controlling the brightness and color of the LED lamp bead 1 and the position of the lens 2, the light characteristics of the surgical laparoscope lamp can be adjusted. It can also provide a variety of color light sources to meet the needs of different surgical operations and provide high-quality lighting conditions for surgery.

[0044] In one embodiment of the present disclosure, lens 2 may be a TIR lens 2, i.e., a total internal reflection lens 2, which can improve the utilization rate of the colored light generated by the LED lamp bead 1. The TIR lens 2 has the advantages of good light focusing and high light concentrating effect. It can integrate the light emitted by a square light source into a circular light spot. The light emitted by the LED lamp bead 1 passes through the inner side wall of the TIR lens 2 and is concentrated and emitted to form a circular light spot.

[0045] At the same time, different light control effects can be achieved by changing the optical design and parameter selection of the lens 2, such as changing the size of the illumination area, controlling the focusing degree of the light, etc.

[0046] In addition, the material of lens 2 can determine the transmission efficiency and uniformity of light. Different materials have different refractive indices and transmittances, which have different effects on the propagation and focusing performance of light. Choosing the right lens 2 material can improve the collection efficiency and uniformity of lens 2.

[0047] In the embodiment of the present disclosure, the lens 2 can be made of PMMA material, which can make the lens 2 have better stability and reflection effect, which is beneficial to improving the service life of the lens 2. It can also improve the light collection efficiency of the lens 2, thereby making the light spot formed by the lens 2 more uniform.

[0048] In one embodiment of the present disclosure, Figure 1As shown, the light input end of the lens 2 is recessed inward to form a receiving groove 22. The sidewalls of the receiving groove 22 are curved and smoothly transition to the end face of the light input end of the lens 2. The LED lamp bead 1 is disposed in the receiving groove 22. The bottom of the receiving groove 22 is flat, which facilitates the colored light generated by the LED lamp bead 1 to illuminate the interior of the lens 2. The curved sidewalls of the receiving groove 22 can reflect the colored light generated by the LED lamp bead 1 onto the sidewalls inside the lens 2, which is beneficial to improving the utilization rate of the colored light generated by the LED lamp bead 1.

[0049] In one embodiment of the present disclosure, the light-emitting surface of the LED lamp bead 1 is uniformly and densely distributed with a plurality of beaded micro-surfaces to homogenize the color light generated by the LED lamp bead 1. For example, the light-emitting surface of the LED lamp bead 1 is hemispherical, and the hemispherical surface of the LED lamp bead 1 is composed of a plurality of uniformly and densely distributed micro-hemispherical surfaces, thereby achieving the effect of homogenizing the color light generated by the LED lamp bead 1, and then making the light spot output by the lens 2 more uniform.

[0050] At the same time, the light source generated by LED lamp bead 1 can have Lambertian or quasi-Lambertian light source characteristics, and the luminous angle of its output light is 180°. The larger the beam angle of the light output by LED lamp bead 1, the softer the light it produces. That is, within the illumination range of LED lamp bead 1, the light it produces can be more uniform, which helps the light form a more uniform light spot after being projected and reflected by lens 2.

[0051] In one exemplary embodiment of the present disclosure, the colored light generated by LED lamp bead 1, after being reflected by lens 2, can form a light spot ranging from 1600mm to 1900mm on a surface 1000mm from the light output end of lens 2. In other words, by adjusting the illumination intensity of LED lamp bead 1 from a set minimum to a set maximum value, the light projected and reflected by lens 2 expands the light spot range formed on a surface 1000mm from the light output end of lens 2 from 1600mm to 1900mm.

[0052] In an exemplary embodiment of the present disclosure, after the colored light generated by the LED lamp bead 1 is reflected by the lens 2 , the uniformity of the light spot formed on the surface 1000 mm away from the light output end of the lens 2 is 60%.

[0053] In the field, the equivalent diameter of a light spot is typically calculated by specifying the geometry formed by a specific percentage of points with maximum intensity on the light spot. For example, the equivalent diameter of the light spot can be determined based on the geometry formed by the points with 10% of the maximum intensity, and the equivalent diameter of the light spot in this case can be expressed as D10. For another example, the equivalent diameter of the light spot can be determined based on the geometry formed by the points with 50% of the maximum intensity, and the equivalent diameter of the light spot in this case can be expressed as D50. The uniformity of the light spot can be calculated by dividing D50 by D10.

[0054] In this embodiment, after the light generated by the LED lamp bead 1 is reflected by the lens 2, the uniformity D50 / D10 of the light spot formed on the surface 1000 mm away from the light output end face of the lens 2 is 60%.

[0055] The present disclosure also provides a shadowless lamp, including the aforementioned laparoscope lamp for surgery. The laparoscope lamp is mounted on the shadowless lamp and can rotate with the shadowless lamp to adjust its position during surgery, thereby facilitating the timely formation of a clear light spot in the surgical area and assisting in the smooth progress of the surgery.

[0056] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the invention disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.
