[0038] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0039] 1. A three-dimensional reciprocating sampling and detection mechanism is set up. Through the cooperation between the various components inside the three-dimensional reciprocating sampling and detection mechanism, the sampling process of the auxiliary diagnostic equipment is optimized. Through the arc-shaped motion structure design between the components inside the moving sampling top box, the movement trajectory of the central sampling lens and the micro sampling lens can be close to the contour shape of the patient's skin, thereby effectively preventing image distortion during the sampling process of the auxiliary diagnostic equipment and improving the overall sampling accuracy of the auxiliary diagnostic equipment. At the same time, through the pressure sensor and the sampling lens, the hardness and deep internal structure of the lesion area can be collected and sampled, thereby effectively expanding the types of parameters for the detection and sampling of the auxiliary diagnostic equipment and improving the diagnostic accuracy of the auxiliary diagnostic equipment.

[0040] Meanwhile, the structural design of the guide ring frame and drive ring rod fixed track reduces the difficulty of debugging during equipment use and ensures that the tilt angle and position of the images captured by the central sampling lens remain consistent. This effectively reduces the difficulty of image stitching in the later stages of auxiliary diagnostic equipment and improves the overall efficiency of the auxiliary diagnostic equipment. At the same time, the cooperation of the dual drive steering motor and drive rubber wheel makes the rotation process of the drive ring rod smoother, thereby effectively improving the overall stability of the internal components of the auxiliary diagnostic equipment. In addition, the use of multiple sets of supplementary light plates to provide multi-angle supplementary lighting to the patient's skin effectively improves the clarity of the images captured by the central sampling lens and the macro sampling lens, further enhancing the overall effectiveness of the auxiliary diagnostic equipment.

[0041] 2. A top-clamping isolation mechanism is installed. Through the cooperation of the various components inside the top-clamping isolation mechanism, the cleaning process of the top of the auxiliary diagnostic equipment is optimized. The quick replacement of the light-transmitting paper on the top of the supporting lighting bed board enables rapid cleaning of the top of the supporting lighting bed board. This prevents debris from falling off during the test from adhering to the top of the supporting lighting bed board and being contacted by subsequent patients. This effectively avoids cross-infection between different patients using the auxiliary diagnostic equipment, thereby effectively improving the overall safety of the auxiliary diagnostic equipment.

[0042] Meanwhile, the cooperation between the various components connected to the storage isolation end box and the cutting support narrow strip ensures that the isolation light-transmitting paper can be quickly clamped and limited during replacement, ensuring that the isolation light-transmitting paper will not shift randomly during use. This effectively improves the overall efficiency of replacing and installing the isolation light-transmitting paper. Furthermore, the cooperation between the installation tilting groove and the sealing angled end cap allows for quick replacement of the installation rotating rod, further improving the overall ease of use of the auxiliary diagnostic equipment.

[0043] 3. The diagnostic system integrates multiple functional modules to achieve high-resolution acquisition and intelligent diagnosis of skin lesion images. Combining pressure sensors and optical control technology, the system can automatically adjust the shooting focal length and light intensity according to the contact situation, adapting to both horizontal and handheld acquisition methods, meeting the requirements of dermoscopy contact imaging, enhancing the localization of small lesions and multi-label classification capabilities, supporting embedded deployment, and combining decision trees and medical knowledge graphs to complete pathological feature extraction and rule matching. The auxiliary decision module can automatically generate structured diagnostic reports, supporting case similarity retrieval, drug recommendations, contraindication reminders, and medical insurance comparison. It also supports remote revision by doctors, realizing human-machine collaborative diagnosis and treatment. The overall system has advantages such as high diagnostic efficiency, strong adaptability, and high level of intelligence, and is suitable for primary medical institutions and telemedicine scenarios, effectively supporting early screening and intelligent auxiliary diagnosis of skin diseases.

[0044] In summary, the cooperation between the three-dimensional reciprocating sampling and detection mechanism and the top clamping isolation mechanism optimizes the sampling, detection, and cleaning process of the auxiliary diagnostic equipment. Multi-point, multi-angle sampling and detection via the central sampling lens and macro sampling lens, combined with overall and localized imaging, allows medical personnel to quickly and accurately diagnose the location, distribution, and spread of lesions on the patient's epidermis using combined photographs. Furthermore, microscopic sampling of localized details in the lesion area effectively improves the overall diagnostic efficiency and effectiveness of the auxiliary diagnostic equipment. The rapid cleaning and replacement process maintains the overall cleanliness of the auxiliary diagnostic equipment, effectively preventing cross-infection during patient use and enhancing the overall safety of its use.

An auxiliary lighting plate is provided inside the top surface of the supporting lighting bed plate 2. The outer side of the drive translation slider 404 is tightly slidably fitted with the inner wall of the limit guide groove 401.

[0063] A guide ring frame 405 is fixedly connected to the top of the drive translation slider 404. A drive ring rod 406 is slidably engaged inside the guide ring frame 405. A movable sampling top box 407 is embedded and assembled in the middle of the top side of the drive ring rod 406. A central sampling lens 408 is embedded and installed in the middle of the bottom surface of the movable sampling top box 407.

[0065] Both sides of the outer bottom surface of the guide ring frame 405 are fixedly connected to the mounting inclined plate 413.

[0066] An arc-shaped mounting plate 416 is embedded in the outer edge of the guide ring frame 405.

The positions of the laser distance sensors 419 are aligned with each other. Through the cooperation between the components inside the three-dimensional reciprocating sampling and detection mechanism 4, the detection and sampling process of the auxiliary diagnostic equipment is optimized. Through the arc-shaped motion structure design between the components inside the moving sampling top box 407, the movement trajectory of the central sampling lens 408 and the micro sampling lens 411 can approach the contour shape of the patient's skin, thereby effectively preventing image distortion during the sampling process of the auxiliary diagnostic equipment and improving the overall sampling accuracy of the auxiliary diagnostic equipment.

The patient then lies flat on the top surface of the supporting lighting bed board 2. When it is necessary to take pictures and samples of the lesion area on the patient's skin, the driving translation motor 402 drives the horizontal driving screw 403 to rotate. During the rotation of the horizontal driving screw 403, the driving translation slider 404 slides horizontally along the inside of the limiting guide rectangular groove 401. The sliding of the driving translation slider 404 drives the guide ring frame 405 and its components to move synchronously. The movement of the guide ring frame 405 drives the driving ring rod 406 and the moving sampling top box 407 to move horizontally. During the movement of the moving sampling top box 407, the central sampling lens 408 takes a picture of the overall distribution of the lesion area on the outside of the patient's skin to analyze and record the proportion and distribution area of ​​the lesion area on the patient's skin.

[0090] When it is necessary to perform targeted sampling on the patient's skin, after the guide ring frame 405 is moved to a suitable position by the drive translation motor 402, the drive steering motor 414 on the side of the mounting inclined plate 413 drives the drive rubber wheel 415 to rotate. During the rotation of the drive rubber wheel 415, the drive ring rod 406 rotates along the inside of the guide ring frame 405. During the rotation of the drive ring rod 406, the moving sampling top box 407 deflects to the direction to be sampled. Then, the corresponding electric telescopic drive rod 409 is activated to drive the pressure sensor 410 to extend towards the patient's skin. The pressure sensor 410 samples and detects the distance between the patient's skin and the moving sampling top box 407 and the hardness of the skin. Then, the surface features of the skin at the lesion site are photographed and sampled by the macro sampling lens 411. Then, the deep features of the skin at the lesion site are sampled by the sampling lens 412.

[0091] When individual information collection and examination are required, the mobile sampling top box 407 can be removed to facilitate use for different patients, and the operation is more convenient.

[0092] Meanwhile, when sampling the patient's diseased skin, the supplementary light plate 417 can be installed inside the guide ring frame 405 by installing the arc plate 416, and the supplementary light plate 417 can provide supplementary light to the imaging area, thereby effectively improving the clarity of the imaging area. The guide ring frame 405 is further supported by the limiting support slider 418, and the horizontal position of the guide ring frame 405 is detected by the laser distance sensor 419, thereby effectively improving the stability and displacement accuracy of the auxiliary diagnostic equipment.

[0093] When cleaning the top surface of the supporting lighting bed board 2 is required to complete a single inspection, the insulating light-transmitting paper 508 that has been used on the top of the supporting lighting bed board 2 is cut off by the cutting tool in conjunction with the cutting support narrow strip 512. Then, the limiting pressing round block 511 is swung upward to remove the limiting of the insulating light-transmitting paper 508 on the top of the supporting lighting bed board 2, and the insulating light-transmitting paper 508 is removed as a whole to achieve the cleaning of the top of the supporting lighting bed board 2.

[0094] When it is necessary to replace the new light-transmitting insulating paper 508, the mounting rod 505 is installed into the storage insulating end box 502 through the mounting inclined groove 503, and the side of the storage insulating end box 502 is isolated and protected by the sealing inclined end cover 504. Then, the cleaning personnel pull the new light-transmitting insulating paper 508 from the outside of the storage cylinder 507 and lay it on the top surface of the supporting lighting bed board 2. Then, the deflection swing box 509 and the telescopic swing rod 510 drive the limiting pressing block 511 to swing. During the swing of the limiting pressing block 511, it is locked into the pressing limiting slot 501. Then, through the cooperation between the pressing limiting slot 501 and the limiting pressing block 511, the light-transmitting insulating paper 508 is pressed and limited, thereby realizing the replacement of the light-transmitting insulating paper 508 and preventing the light-transmitting insulating paper 508 from shifting or slipping during use.

[0095] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
