Description

Endoscope mirror lens illumination structure improvement

The present invention is an illumination structure improvement of an endoscope lens, mainly providing an illumination ring between the lens portion and the distal end of the endoscope tube body, and providing an auxiliary illumination structure for uniform illumination by a 360-degree complete ray projection. , to equalize the brightness of the cavity, and to ensure that the real image of the captured image.

The light-emitting technology of the conventional endoscope is the first to use the glass fiber for light guiding, and the light source behind the catheter is transmitted to the front end to provide the illumination function required for lens imaging, but the material is easily broken during the processing. It is difficult to manufacture, and if it breaks during application, the broken fiber has certain damage to the human body, is not easy to remove, and is costly, so it is not practical. The structure of the improved lens illumination is known as shown in FIG. 1. The main body is a cylindrical lens portion (1), which is mainly provided with a plurality of illuminants (11) in the forward direction, which are arranged in a ring shape and are imaged. The module (12) is disposed at a middle position thereof, and the illuminant (11) is usually a light-emitting diode. The design is used, since the illuminant (11) is positively illuminating, the use of the endoscope is often It is applied in the cavity of a liquid-containing organ. Because the cavity has a smooth surface and is filled with liquid, it is easy to form a right angle with the light emitted by the illuminator, and a reflection phenomenon occurs. When the image is captured, a light spot is formed and becomes a blind spot of sight. When the operation is performed, a considerable degree of risk is added. In addition, since the light source of the design is concentrated at the front end, there is a danger of high temperature overheating during the operation, so To be improved. The applicant of this case designed an improved design, such as the Taiwan Patent No. 524474 "Improvement of Endoscope Mirroring Lens Device", which mainly opened light-transparent holes on the side of the lens portion and combined with light-transmissive sheets. A longitudinal illuminator is added to the interior of the lens portion to allow the light to be scattered outwardly through the transparent sheet to increase the overall brightness for illuminating the interior of the body cavity, thereby facilitating the shooting to obtain a clearer image. However, although the structure provides supplementary light from the side, since it is located on both sides, the generated light is concentrated on both sides of the lens, and light and shadow are still formed, and there is a doubt that misjudgment is caused, so that there is still room for improvement. .

The present invention is an improved illumination structure of an endoscope camera lens, and an auxiliary illumination structure is mainly arranged between the lens portion and the distal end of the endoscope tube body, which is a ring body, and includes a plurality of illuminators arranged in a ring shape, and the whole is transparent. The aura is covered and combined into a light ring. When used, the light of each illuminator can be uniformly scattered outward through the transparent ring. By projecting a complete 360-degree circular light, the cavity can be better added. In addition to the lighting efficiency, its comprehensive and uniform illumination can provide balanced brightness in the cavity to ensure the true appearance of the captured image, avoid false positives, and achieve progressive results.

Please refer to Figure 2~5. This is an endoscope lens. The structure is modified, and is mainly designed with an illumination ring (2) combined between the lens portion (3) and the distal end of the endoscope tube body (4) to form a ring-shaped auxiliary illumination structure, and the illumination ring (2) includes The inner part is provided with a plurality of illuminators (21) arranged in a ring shape, and the whole outer part is covered by a transparent ring (22), and the outer part of the transparent ring (22) forms a middle section (222), an upper edge (221) and a lower part. The edge (223) has three portions, wherein the outer diameter of the segment (222) is equal to the outer diameter of the lens portion (3) and the tube body (4), and the outer diameters of the upper edge (221) and the lower edge (223) are Corresponding to the inner diameter of the lens portion (3) and the tube body (4), the illumination ring (2) can be closely integrated with the lens portion (3) and the distal end of the tube body (4), and each illuminant (21) ) is located inside the middle section (222) of the light-transmitting ring (22). Therefore, in use, the light of each illuminant (21) can be projected 360 degrees from the middle (222) position of the light-transmitting ring (22) of the illumination ring (2), resulting in complete and comprehensive illumination when the physician is at When using the endoscope to detect the human body, in addition to improving the illumination efficiency of the space in the test cavity, its 360-degree uniform illumination can provide a more balanced effect in the brightness of the cavity, thus ensuring internal vision. The images taken by the mirror are more realistic, which can avoid the occurrence of misjudgment, and are creative and progressive.

Under the creative structure of the creation, a combination of illuminants of different colors and wavelengths can be used to provide a medically advantageous diagnosis, and a light adjustment mechanism is used to change the brightness of the illuminating color or illuminance, thereby increasing the overall progress and Practicality.

In summary, the improvement of this creation is more advanced than the known designs, so it has met the requirements of the new patent, and applied in accordance with the law, and please give it as soon as possible.
