[0079] Implementation case:

[0080] Innovative handle 4 top end layout implementation: in actual clinical operation, medical staff holds the ultra-fine rigid endoscope equipped with the structure of the utility model. Because the top end of the handle 4 is in the form of an equilateral triangle, the inclined angle design of the ergonomic interface opening makes the doctor naturally stretch the hand muscles when holding the handle 4, and it is not easy to cause fatigue after a long time of operation. For example, when performing a breast ductoscopy, the doctor can easily and accurately connect the external camera bayonet with the camera bayonet, ensuring fast and stable transmission of image signals; at the same time, the optical fiber bundle introduced from the outside is tightly connected with the corresponding connecting structure, and bright illumination in the cavity is achieved instantly. The special fixing method of the handle 4 and the camera and external light guide connecting structure can significantly enhance the stability of the hand-held operation, and even if the doctor makes a slight adjustment, the endoscope will not shake, greatly improving the accuracy of the operation.

[0081] Ultra-fine mirror handle top layout implementation: taking ophthalmic endoscopy as an example, the doctor can quickly switch components at the top of the ultra-fine mirror handle according to different examination needs. If you need to observe the eye micro lesions, you can immediately replace the imaging eyepiece with a high-resolution camera bayonet and connect it through a quick contact port without complicated disassembly and installation steps. When cleaning the foreign matter in the eye, the straight-line type minimally invasive instrument channel 1 (working channel inlet and outlet) can be connected to the corresponding minimally invasive instrument, and the rotatable illumination interface 2 (illumination fiber-optic interface) can also be easily connected to the appropriate illumination optical fiber, enhancing the illumination effect and making the operation field more clear. The whole process is efficient and convenient, significantly shortening the diagnosis and treatment time.

[0082] Minimally invasive instrument channel structure implementation: in prostate puncture surgery, the metal tube perpendicular to the luer interface of the handle 4 plays a key role as a minimally invasive instrument access channel. The doctor inserts the specially designed puncture needle through the channel accurately, and the accurate size specification of the metal tube ensures that the puncture needle fits tightly with the channel, smoothly advancing without obstruction, avoiding the shaking of the puncture needle caused by the too wide channel, which affects the puncture accuracy, and preventing the puncture needle from being stuck or even damaged due to the too narrow channel. At the same time, the reasonable physical structure design of the channel effectively protects the puncture needle, prolongs its service life, and provides a solid hardware guarantee for the smooth operation of the surgery.

[0083] Illumination interface design implementation: when performing spectral analysis of lung puncture nodules, the doctor first connects the external illumination device fixed on the handle 4 to the illumination interface through the rotary fixing structure to ensure stable connection. The external light source is efficiently transmitted to the front end of the endoscope insertion part 5 through the built-in light guide fiber bundle, uniformly illuminating the lung nodule area. If the interface specifications of the existing external illumination equipment in the hospital do not match the standard interface, the light guide beam interface designed with custom specifications can easily realize adaptive connection with the equipment, meet the lighting needs in different scenarios, and provide good lighting conditions for the doctor to accurately observe the nodule.

[0084] Eyepiece assembly structure implementation: during nasopharyngolaryngoscopy, the doctor observes the cavity through the eyepiece assembly. The eyepiece assembly and the imaging fiber are carefully designed with a rotating joint structure to ensure the stability of the connection and prevent the image transmission from being affected by shaking during operation. The unique coupling structure of the optical system of the eyepiece assembly and the built-in imaging fiber allows the actual scene of the nasopharynx and throat collected by the imaging fiber at the front end to be clearly and accurately displayed in the eyepiece. The doctor can clearly see the subtle changes in the mucosa and the location of foreign objects, providing intuitive and reliable visual evidence for accurate diagnosis.

[0085] Camera system connection design implementation: in the multidisciplinary consultation scenario of digestive endoscopy, the eyepiece outer circle adopts a C-standard buckle structure, which can quickly connect with the C-buckle camera system. The image observed by the doctor's eye through the eyepiece is quickly converted into a video signal by the camera viewfinder and displayed clearly on the display screen. At this time, the gastroenterologist, pathologist, and other relevant medical staff can observe the image simultaneously and discuss and analyze around the image to jointly develop the best diagnosis and treatment plan, greatly improving information sharing and collaboration efficiency and avoiding diagnosis and treatment errors caused by poor information communication.

[0086] Miniature camera system adaptation design implementation: during long-term ventriculoscopy surgery, the doctor can observe and operate through the eyepiece assembly at the beginning of the surgery. As the surgery time prolongs, to reduce hand fatigue and the burden of the ultra-fine scope, the eyepiece can be easily detached and connected to the C-buckle miniature camera system. The advanced image acquisition and conversion function module built-in the miniature camera system quickly acquires and converts the image on the imaging fiber surface to the built-in camera sensor, and the image is clearly displayed on the display after efficient video processing. The doctor can clearly observe the surgical area while maintaining stable operation, providing a flexible and convenient operation option for the smooth completion of the surgery.

[0087] The structure of the super-thin endoscope insertion part 5 is implemented as follows: when performing a fine breast ductoscopy operation, the inside of the super-thin endoscope insertion part 5 is closely cooperated by the built-in working channel tube, the imaging optical fiber and the built-in illumination optical fiber according to a specific layout. During the insertion of the breast duct, the working channel tube can deliver drugs or perform micro tissue sampling, the imaging optical fiber collects real-time images inside the breast duct, and the built-in illumination optical fiber provides stable and uniform illumination. The close and stable physical connection of each part and the optimized spatial arrangement ensure that the insertion part 5 works efficiently and stably in the narrow breast duct, and the doctor can accurately perform the operation, improve the success rate of the operation and reduce the damage to the patient.

[0088] The light overall structure design is implemented as follows: in the mobile diagnosis and treatment scene, the doctor carries the super-thin endoscope equipped with the self-defined specification external light guide beam and the miniature camera to the patient's bedside. The light overall structure design of the endoscope makes it easy to carry, and the doctor can quickly connect each part and form an overall structure. During the operation, the stability and reliability of the device are fully embodied, and even in the relatively unstable bedside environment, the diagnosis and treatment work can be normally performed, the timely and convenient medical service is provided for the patient, and a new and efficient solution is brought for the diagnosis and treatment of the micro part.
