Description

Technical Field

[0001] The present application relates to the field of endoscopes, and in particular to an endoscope lighting device and an endoscope. Background Art

[0002] Existing endoscopes generally have an LED light source at the end that is inserted into the human body for illumination. However, the brightness of the LED light source is relatively low. In order to increase the brightness of the light source, it is generally necessary to increase the power supply to ensure the brightness. In addition, in order to ensure the brightness, the size of the LED light source also needs to be increased, which results in a larger light source and more heat.

[0003] When using a laser emitter as a light source, although the laser emitter is smaller and brighter, the laser excitation fluorescence light source has a large power and will generate a huge amount of heat, which is not conducive to heat dissipation; if the laser excitation fluorescence light source has a low power, it cannot meet the conditions for exciting fluorescence.

[0004] In addition, lasers are harmful to human tissue and cannot be used to directly irradiate the human body.

[0005] Therefore, there is an urgent need for an endoscope lighting device and an endoscope that has a small structure when inserted into the human body, does not generate excessive heat in the human body, does not cause harm to the human body, and can meet different lighting requirements to overcome the above-mentioned defects.

[0012] Preferably, the light guiding medium is quartz optical fiber.

[0013] Preferably, the endoscope lighting device further comprises a filter for filtering light heat, and the filter is arranged between the light source device and the input end of the light-guiding medium.

[0014] Preferably, the fluorescent medium is made of a curved or bent silicon dioxide structure coated with a fluorescent material.

[0015] To achieve the above objectives, an embodiment of the present application provides an endoscope, comprising any of the endoscope lighting devices described above.

[0016] Preferably, the endoscope includes an internal end for inserting into the human body and an external end for external control, the fluorescent medium is located at the internal end, and the light source device is located at the external end.

The fluorescent medium is scattered, while the light of another wavelength emitted by the laser is not absorbed by the fluorescent material. It directly passes through the fluorescent material and is scattered by the curved or bent fluorescent medium. Moreover, because the light source device has a light-guiding medium, it does not need to be inserted into the human body and the heat generated by it is isolated by the light-guiding medium, so that the light scattered by the fluorescent medium no longer carries too much heat. Moreover, the curved or bent fluorescent medium increases the range of light irradiation while scattering the light, so that the structure of the endoscope lighting device of the present application that needs to be inserted into the human body is small, does not generate too much heat in the human body, does not cause harm to the human body, and can meet different lighting requirements.

Of course, according to actual conditions, in other embodiments, the fluorescent medium 30 can also be other curved shapes to achieve the above-mentioned effect, so it is not necessary to This is the limit; the fluorescent medium 30 is disposed at the output end 20b of the light-guiding medium 20. The fluorescent medium 30 is made of a fluorescent material and silicon dioxide, so that the fluorescent medium 30 absorbs light of a specific wavelength through the fluorescent material and converts it into light of another specific wavelength 11a. In this way, the wavelength of the light emitted by the light source device 10 and the type of fluorescent material can be selected according to actual needs, thereby utilizing the absorption wavelength of the fluorescent material and the wavelength of the secondary emission to convert the wavelength color to achieve a color-changing effect. At the same time, the light source device 10 can also emit light 12a of a wavelength that is not absorbed by the fluorescent material, thereby avoiding wavelength conversion by the fluorescent material. More specifically, as follows:

[0029] For example, the fluorescent material absorbs the light emitted by the light source device 10 and converts it into general white light for illumination. It can also be converted into light for exciting endoscopic contrast agent (ICG) to enhance the contrast effect on cancer cells, but the present invention is not limited thereto.

[0030] like Figure 1 As described above, the light source device 10 is a laser to ensure sufficient light brightness and make the light source device 10 smaller in structure. Of course, according to actual conditions, the light source device 10 can also be an LED lamp, so it is not limited to this.

[0031] like Figure 1As shown, light source device 10 includes a first laser 11 for emitting laser light of one wavelength and a second laser 12 for emitting laser light of another wavelength. A fluorescent medium 30 is configured to convert the laser light emitted by first laser 11 into light 11a of a certain wavelength. Light 12a emitted by second laser 12 is not converted by fluorescent medium 30 but is merely scattered by fluorescent medium 30. Depending on the actual situation, light source device 10 may include only lasers whose wavelengths can be converted by the fluorescent material, or may include lasers whose wavelengths can be converted by the fluorescent material in addition to two, three, four, or other lasers whose wavelengths cannot be converted by the fluorescent material. The present invention is not limited to this.

[0033] like Figure 1 As shown, the light-guiding medium 20 is a quartz optical fiber to ensure the conduction of laser light and the insulation of heat.

[0034] Not limited to the drawings, the endoscope lighting device 1 of the embodiment of the present application further includes a filter for filtering light heat, and the filter is disposed between the light source device 10 and the input end 20 a of the light guide medium 20 .

[0035] Without being limited to the accompanying drawings, the endoscope of the embodiment of the present application includes an endoscope lighting device 1; preferably, the endoscope includes an internal end for inserting into the human body and an external end for external control, the fluorescent medium 30 is located at the internal end, and the light source device 10 is located at the external end, so that the light source device 10 is outside the human body during the use of the endoscope lighting device 1, thereby facilitating the heat dissipation of the light source device 10 and preventing the heat generated by the light source device 10 from being transferred to the internal end.

[0036] Not limited to the drawings, a heat dissipation structure is further provided on the external end to facilitate heat dissipation of the light source device 10 .

The light source device 10 is used to emit light, the light-guiding medium 20 is used to transmit laser light, and the light source device 10 is coupled to the input end 20a of the light-guiding medium 20; the fluorescent medium 30 is arranged at the output end 20b of the light-guiding medium 20, and the fluorescent medium 30 is used to scatter the light incident therein outward. The fluorescent medium 30 is made of fluorescent material and silicon dioxide. The fluorescent medium 30 absorbs the absorbed light of a specific wavelength by means of the fluorescent material and converts it into light of another specific wavelength. In this way, the laser light of one wavelength emitted by the light source device 10 is absorbed by the fluorescent material and converted into light of other wavelengths. , and is scattered by the curved or bent fluorescent medium 30, while the light of another wavelength emitted by the laser is not absorbed by the fluorescent material, and it directly passes through the fluorescent material and is scattered by the curved or bent fluorescent medium 30. Moreover, the curved or bent fluorescent medium 30 increases the light irradiation range while scattering the light. Moreover, because the light source device 10 has the light-guiding medium 20, it does not need to be inserted into the human body and the heat generated by it is isolated by the light-guiding medium, so that the light scattered by the fluorescent medium 30 no longer carries too much heat, thereby making the structure of the endoscope lighting device 1 of the present application that needs to be inserted into the human body small, does not generate too much heat in the human body, does not cause harm to the human body, and can meet different lighting requirements. In addition, since the endoscope of the embodiment of the present application includes the above-mentioned endoscope lighting device 1, the structure of the endoscope of the embodiment of the present application that needs to be inserted into the human body is small, does not generate too much heat in the human body, does not cause harm to the human body, and can meet different lighting requirements.

[0038] The above disclosure is only a preferred example of the present application, and its purpose is to facilitate the understanding and implementation of those skilled in the art. However, it cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made within the scope recorded in the present application still fall within the scope covered by the present application.
