Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an otolaryngological endoscopy and imaging system equipped with a Wood's lamp and its working method. Background Technology

[0002] The Wood's lamp was invented in 1903 by American physicist Robert Wood. It was first used as a practical medical tool in dermatology in 1925 for diagnosing fungal infections of the hair. The Wood's lamp uses a high-pressure mercury lamp as its light source, emitting light waves with a wavelength of 320nm (400nm) through a barium silicate filter containing 9% nickel oxide, with a peak at 365nm. The Wood's lamp has a relatively low output power, typically 1mW / cm². 2 It is mainly used to detect pigmentary disorders, skin infections, and porphyrin metabolism disorders.

[0003] The anatomical features of the human ear and nose are delicate structure, small openings and deep cavities, and limited field of vision.

[0004] Fungal colonization of the external auditory canal and sinuses can cause fungal otitis externa and fungal sinusitis, common diseases in otolaryngology. Because they are localized lesions, treatment primarily involves topical medications. However, fungal infections are characterized by long treatment cycles, high recurrence rates, and difficulty in assessing the effectiveness of local antifungal therapy. Clinically, patients often seek medical attention due to recurrent fungal infections, resulting in a prolonged course of illness. Currently, there is no method for directly evaluating the effectiveness of local antifungal treatment. An otolaryngoscope is an optical device used in otolaryngology that allows for detailed examination of the nasal cavity, ear canal, and other areas. Otorhinolaryngology is a routine examination method with a very high usage rate. It allows for close observation and detailed examination. Using a cold light source, it can examine the inside of the ear for issues such as ulceration and swelling of the ear mucosa, fluid accumulation, tympanic membrane perforation, foreign objects, and ear canal patency. For the nose, it can examine the nasopharynx for patency, polyps, lumps, bone structure deviation or fracture, and nasal discharge. However, it cannot detect fungal or spore-level infections in one step.

[0005] Therefore, there is an urgent need for an endoscopic examination and imaging system for the ear and nose that can directly observe the treatment effect of fungal infections and specific bacterial infections in the ear and nose. Summary of the Invention

[0006] The purpose of this invention is to overcome the deficiencies of the prior art by providing an otolaryngological endoscopy and imaging system with a Wood's lamp and its working method. By combining the Wood's lamp with an otolaryngological endoscope, the endoscope's functionality is enhanced, and the detection rate of specific fungal and bacterial infections is improved and accelerated. Combining the advantages of the Wood's lamp and the otolaryngological endoscope can enhance the endoscope's functionality and improve and accelerate the detection rate of specific fungal and bacterial infections.

[0012] Furthermore, the other end of the light guide cable is positioned opposite to the light-emitting lens assembly.

[0013] Furthermore, the light emitted by the xenon lamp is reflected by the concave mirror and then passes sequentially through a rotating glass aperture, a first dimming lens, a rotating nickel hydride filter aperture, a second dimming lens, and finally through a light guide cable.

[0042] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Component models, material names, connection structures, and other features not explicitly described in this technical solution are considered common technical features disclosed in the prior art.

[0043] This invention first uses a xenon lamp 2, a common cold light source for endoscopes, to emit white light with a wavelength of 190–1100 nm. A concave reflector 1 is placed behind the xenon lamp to focus all the light emitted by the xenon lamp 2 forward, reducing energy loss. The light passes through a rotating glass aperture 5, which is a glass with a continuously varying diameter, used to adjust the intensity of the white light (e.g., ...). Figure 2 The light continues to pass through the first dimming lens 3, where it is focused and integrated. The light then continues forward through the rotating nickel hydride filter aperture 6 to obtain Wood's lamp light, with a wavelength of 320–400 nm. The intensity of the Wood's lamp light can also be adjusted by changing the aperture size (e.g., ...). Figure 3 The light passes through the second dimming lens 4 to obtain stable parallel light, and continues forward through the light guide cable 7, the operation and connection part 8, the rigid lens 9, and finally through the illumination lens assembly 10 to illuminate the inspection area. The rigid lens 9 is also equipped with a camera lens assembly 11 and a front-end image signal processing assembly 12 to capture real-time images of the inspection area, and convert the image signal to the image processor 13 via the data cable 15. After further image processing, the image is displayed and observed on the monitor 14.

When the absolute position of the described object changes, the relative positional relationship may change. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] It should be noted that in this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0050] The concave mirror 1, xenon lamp 2, rotating glass aperture 5, first dimming lens 3, rotating nickel hydride filter aperture 6, and second dimming lens 4 are sequentially arranged on the same straight line, i.e., on the same optical path. The axes of the rotating glass aperture 5 and the rotating nickel hydride filter aperture 6 are deviated from the optical path, so that the optical path passes through the glass aperture body 5-3 on the rotating glass aperture 5 and the nickel hydride filter aperture body 6-3 on the rotating nickel hydride filter aperture 6. The second dimming lens 4 is arranged opposite to one end of the light guide cable 7, so that the optical path passes through the light guide cable 7 and the light passes through the light guide cable 7. The operation and lens device is connected to the light source device through the light guide cable 7.

[0051] The operation and lens device includes an operation and connection part 8 and a rigid lens 9; the light guide cable 7 passes through the operation and connection part 8 and is connected to the rigid lens 9; the rigid lens 9 is used for illumination and imaging, and the rigid lens 9 is an insertion part.

[0052] The rigid lens 9 houses an illumination lens assembly 10, a camera lens assembly 11, and a front-end image signal processing assembly 12; the camera lens assembly 11 is connected to the front-end image signal processing assembly 12. The illumination lens assembly 10 is positioned opposite to the other end of the light guide cable 7, specifically, the other end of the light guide cable 7 is opposite to the illumination lens assembly 10, so that light is transmitted through the light guide cable 7 and then through the illumination lens assembly 10 to illuminate the specific inspection area to be observed.

[0053] The ENT endoscopy and imaging system also includes an image processor 13 and a display 14; the display 14 and the image processor 13 are connected via a data cable 15; the image processor 13 and the front-end image signal processing component 12 are connected via a data cable 15.

[0054] The light emitted by the xenon lamp 2 is reflected by the concave mirror 1 and then passes sequentially through the rotating glass aperture 5, the first dimming lens 3, the rotating nickel hydride filter aperture 6, the second dimming lens 4, and then through the light guide cable 7.

[0055] The rotating glass aperture 5 includes a first opaque turntable 5-1, a first rotating shaft core 5-2, and a glass aperture body 5-3; the glass aperture body 5-3 is fixedly connected to the first opaque turntable 5-1; the first rotating shaft core 5-2 is connected to the center of the first opaque turntable 5-1.

[0056] The glass aperture body 5-3 is a continuously changing light-transmitting component. The glass aperture body 5-3 is made of glass and is used to adjust the intensity of white light.

[0057] like Figure 2As shown, in this embodiment, the glass aperture body 5-3 is C-shaped, and the width of the glass aperture body 5-3 transitions from a narrower end to a wider end. The first opaque turntable 5-1 has a hole that matches the glass aperture body 5-3 so that the glass aperture body 5-3 can be inserted into the hole.

[0058] The first opaque turntable 5-1 has a first through hole that matches the glass aperture body 5-3, and the glass aperture body 5-3 is inserted into the first through hole.

[0059] The rotating nickel hydride filter aperture 6 includes a second opaque turntable 6-1, a second rotating shaft core 6-2, and a nickel hydride filter aperture body 6-3; the nickel hydride filter aperture body 6-3 is fixedly connected to the second opaque turntable 6-1; the second rotating shaft core 6-2 is connected to the center of the second opaque turntable 6-1.

[0060] The nickel hydride filter aperture body 6-3 is a continuously changing light-transmitting element. The nickel hydride filter aperture body 6-3 is a nickel hydride filter used to adjust the intensity of Wood's lamp light.

[0061] like Figure 3 As shown, in this embodiment, the nickel hydride filter aperture body 6-3 is C-shaped, and the width of the nickel hydride filter aperture body 6-3 transitions from a narrower end to a wider end. The second opaque turntable 6-1 has a hole that matches the nickel hydride filter aperture body 6-3 so that the nickel hydride filter aperture body 6-3 can be locked in the hole.

[0062] The light source device also includes a housing 16. The concave mirror 1, xenon lamp 2, rotating glass aperture 5, first dimming lens 3, rotating nickel hydride filter aperture 6, and second dimming lens 4 are disposed within the housing 16. All components are connected to the inner wall of the housing 16. Figure 4 , 5 As shown, the first rotating shaft core 5-2 of the rotating glass aperture 5 and the second rotating shaft core 6-2 of the rotating nickel hydride filter aperture 6 are both connected to the inner wall of the light source device housing 16.

[0063] The second opaque turntable 6-1 has a first through hole that matches the nickel hydride filter aperture body 6-3, and the nickel hydride filter aperture body 6-3 is inserted into the second through hole.

[0064] The display 14 is connected to the image processor 13 via a data cable 15; the image processor 13 is connected to the front-end image signal processing component 12.

[0065] This embodiment also provides a method for operating an otolaryngological endoscopy and imaging system equipped with a Wood's lamp, the method comprising the following steps:

[0066] White light is emitted through the xenon lamp 2, with a wavelength of 190–1100 nm.

[0067] A concave reflector 1 is installed behind the xenon lamp 2 to focus all the light emitted by the xenon lamp 2 forward and reduce energy loss;

[0068] The light passes through a rotating glass aperture 5, which is configured to have a continuously varying diameter to adjust the intensity of the white light; the light continues to pass through a first dimming lens 3, where the light is focused and integrated.

[0069] The light continues forward through the rotating nickel hydride filter aperture 6 to obtain Wood's lamp light, i.e., the wavelength is 320-400nm. The intensity of Wood's lamp light can also be adjusted by adjusting the aperture size. The light passes through the second dimming lens 4 to obtain stable parallel light, and continues forward through the light guide cable 7, the operation and connection part 8, the rigid lens 9, and finally through the illumination lens assembly 10 to illuminate the inspection area.

[0070] The hard lens 9 is equipped with a camera lens assembly 11 and a front-end image signal processing assembly 12 to capture real-time images of the inspected area and transmit the image signals to the image processor 13 via the data cable 15. After further processing, the images are displayed and observed on the monitor 14.

[0071] In this embodiment, the light-emitting lens assembly 10 can be an optical lens.

[0072] In this embodiment, the camera lens assembly 11 can be an optical lens, which focuses light onto the front-end image signal processing assembly 12. The front-end image signal processing assembly 12 is a front-end image sensor that converts light signals into electrical signals. The image processor 13 is an ISP that processes the signals obtained by the front-end image signal processing assembly 12 to obtain a visual image, which is then displayed and observed on the display 14. Both the front-end image signal processing assembly 12 and the image processor 13 are commercially available components.

[0073] Example 2

[0074] like Figure 6 As shown, this embodiment provides an ENT endoscopy and imaging system equipped with a Wood's lamp. Based on embodiment 1, the rotating nickel hydride filter aperture 6 also includes an additional glass aperture body 6-4.

[0075] The additional glass aperture body 6-4 is mounted on the second opaque turntable 6-1. The additional glass aperture body 6-4 is a light-transmitting component, and the glass aperture body 5-3 is made of glass and is used to transmit white light. Specifically, when the second rotating shaft 6-2 is rotated so that the additional glass aperture body 6-4 is in the light path instead of the nickel hydride filter aperture body 6-3, Wood's lamp light is no longer obtained. The light illuminating the examination area is still 190-1100nm, which can be used for other routine examinations. This allows the light illuminating the examination area by the ENT endoscopy and imaging system equipped with Wood's lamp to be either an adjustable Wood's lamp light or an adjustable cold light source.

[0076] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
