Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to a lighting structure for endoscopes. Background Art

[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has an image sensor, optical lens, light source, mechanical device, etc. It can enter the stomach through the mouth or enter the body through other natural orifices. Endoscopes can be used to see lesions that X-rays cannot show, so they are very useful to doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach or mouth and develop the best treatment plan based on this.

[0003] For example, the Chinese patent publication number CN219089220U, "A needle tube head lighting structure for an endoscope", proposes a needle tube head lighting structure for an endoscope, including an endoscope and a lighting head, a notch is provided on the end of the lighting head away from the lighting lamp, the notch is arranged with an inclined surface, and an insertion cavity is provided on the endoscope. The utility model proposes a needle tube head lighting structure for an endoscope, which is used for dentistry. A notch is arranged at the end of the needle tube lighting head of the endoscope, and a slope of the notch is arranged. When the lighting head is inserted into the endoscope, there is a through hole connected to the insertion cavity on the endoscope. When the insert block moves into the through hole, it contacts with the slope of the notch, and then pushes the lighting head out. The setting of the resist block is that the resist block is moved into the through hole by hand pinching, driving the insert block to push out the lighting head. Because the insert block is slidably limited in the through hole, when the lighting head is removed, it can be placed in the storage port for storage. There is an iron block in the storage port, and there is a magnet at the end of the resist block, so that the resist block is adsorbed in the storage port.

[0004] However, in actual use, the lighting head is fixedly installed on the endoscope by being plugged into the insertion cavity, and the lighting angle is limited. It can only illuminate according to the direction of the endoscope. It is not convenient to adjust the lighting effect of the irradiated area by changing the illumination direction, and it is not convenient to improve the efficiency of pathology search.

[0028] In this embodiment, the driving assembly 6 drives the gear assembly 7 to rotate the rotating sleeve 3 in the mounting sleeve 2, thereby rotating the lighting lamp 4 to change its lighting direction, thereby achieving the purpose of facilitating the adjustment of the lighting effect of the irradiated area, which has the function of facilitating the search for pathology.

[0029] Example 2

[0030] like Figure 1-3 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the cleaning component 8 includes a rotary pump 801, and a power input end 802 is arranged above the rotary pump 801.
