[0002] Lung cancer screening aims to effectively detect lung cancer in its early stages. Currently, the methods for lung cancer screening include: imaging examinations (such as chest X-rays and chest CT scans) and bronchoscopy (looking at the inside of the bronchi through a flexible fiber optic light guide). The current bronchial light guides have poor brightness, resulting in incomplete examinations.

[0003] An existing patent (publication number: CN212319568U) proposes a light-guiding light pipe, which includes a machine box, which is fixedly installed between one end of an insulating tube, a wire is arranged inside the insulating tube, a circuit board is installed inside the machine box, a vibration sensor is installed inside the machine box, the vibration sensor is soldered with a circuit board through pins, a button battery is installed inside the machine box, and one end of the wire is soldered to the circuit board. The light-guiding light pipe provided by the utility model has the functions of being waterproof and easy to replace.

[0004] The above-mentioned light guide tube adopts a technical solution of being waterproof and easy to replace, which is fixedly installed between the machine box and one end of the insulating tube. A wire is arranged inside the insulating tube, a circuit board is installed inside the machine box, a vibration sensor is installed inside the machine box, and the circuit board is soldered with pins.

[0029] The light guide tube body 1 also includes a light guide hose 2, a light inlet tube 3 and a light outlet tube 4. The light guide hose 2 is used for guiding light and being inserted into the trachea to assist the light outlet tube 4 in illuminating the inside of the trachea and performing bronchi inspection. A light guide block 6 is fixed on the top of the light inlet tube 3. A lamp trough 61 is provided at the bottom of the light guide block 6. A lampshade 62 is fixed in the lamp trough 61. Lamp beads 63 are arranged in the lampshade 62. A lens 7 is arranged below the lamp beads 63. When the lamp beads 63 are lit, the lampshade 62 can initially gather the scattered light to improve the irradiation capacity. Then, the light can be further focused through the focusing of the lens 7 to prevent the light source from being dispersed, thereby further improving the light guiding effect and irradiation capacity of the light guide tube body 1. The lens 7 is fixed in the light inlet tube 3. The lens 7 is in the light inlet tube 3 and does not fit the lamp bead 63, thereby further enabling the lens 7 to focus the scattered light, thereby improving the light guiding effect of the light guide tube body 1.

[0030] Embodiment 2

[0031] like Figure 1-Figure 3As shown, a thread 31 is provided at the bottom of the light inlet tube 3, a lens 7 is fixed at one end of the light inlet tube 3 away from the thread 31, a lamp bead 63 is fixed in the light guide block 6, the inner diameter of the light inlet tube 3 is larger than the diameter of the lamp trough 61, the lamp bead 63 does not fit the lens 7, the lamp cover 62 is made of PC resin, the inner wall of the lamp trough 61 and the inner wall of the lamp cover 62 are coated with UV reflective paint, the end of the light inlet tube 3 away from the light guide block 6 is connected to a light guide hose 2, the end of the light guide hose 2 away from the light guide block 6 is fixed to a light outlet tube 4, a sealing rubber 5 is sleeved between the light guide hose 2 and the light outlet tube 4, and a protective lens 8 is fixed to the bottom of the light outlet tube 4. The protective lens 8 is a plane mirror, and the protective lens 8 is made of tempered glass. The inner walls of the light guide hose 2, the light inlet pipe 3 and the light outlet pipe 4 are coated with an aluminized plastic film, which can effectively prevent light from being absorbed by the inner walls of the light guide hose 2, the light inlet pipe 3 and the light outlet pipe 4 during propagation. The length of the light guide hose 2 is 50cm-70cm, which is usually the length that can detect the inside of the trachea of ​​adult males and females. The diameter of the light guide hose 2 is 5mm-8mm, which is usually the diameter of the trachea between teenagers and adults.

[0032] The bottom of the light inlet tube 3 is provided with a thread 31, which is convenient for disassembly and installation of the light inlet tube 3 and the light guide tube 2. The lens 7 is fixed at the end of the light inlet tube 3 away from the thread 31. The lens 7 is arranged near the lamp bead 63, so that the light can be easily focused and the irradiation ability is improved. The lamp bead 63 is fixed in the light guide block 6, which is convenient for the lamp bead 63 to emit light in the light guide block 6. The inner ring diameter of the light inlet tube 3 is larger than the diameter of the lamp groove 61, so that the light can be fully irradiated into the light inlet tube 3. The lamp bead 63 and the lens 7 are not in contact, which is convenient for the lens 7 to focus and prevent the light from being dispersed.

[0033] The lampshade 62 is made of PC resin, which is corrosion-resistant, lightweight and strong. The inner walls of the lamp trough 61 and the inner walls of the lampshade 62 are coated with UV reflective paint, which can fully reflect the light emitted by the lamp beads 63 on the lampshade 62 and the inner wall to form a focusing effect. The light-guiding hose 2 is connected to the end of the light inlet tube 3 away from the light guide block 6. The light of the light inlet tube 3 is transmitted to the light-guiding hose 2. The light outlet tube 4 is fixed to the end of the light guide hose 2 away from the light guide block 6. The light in the light guide hose 2 is then emitted from the light outlet tube 4. A sealing rubber 5 is sleeved between the light guide hose 2 and the light outlet tube 4. The sealing rubber sleeve prevents water from entering between the light guide hose 2 and the light outlet tube 4, and the generated water mist further affects the illumination effect of the light outlet tube 4.

[0034] Working principle: Figure 1-3As shown, the light guide block 6 is placed in one of the hands, and the lamp bead 63 is turned on. A part of the light emitted by the lamp bead 63 is irradiated to the inner wall of the lampshade 62. The inner wall of the lampshade 62 is coated with UV reflective paint, so that the scattered light sources are primarily gathered into the light inlet tube 3.
