As the largest organ of the human body, the skin is directly exposed to the external environment. Therefore, there are many types of skin diseases and diverse clinical manifestations. They may be local lesions or skin manifestations of systemic diseases. In the process of diagnosing skin diseases, corresponding auxiliary diagnostic equipment is needed. For this purpose, a Chinese patent discloses a skin disease auxiliary diagnostic instrument with application number CN201920458450.3. The patent includes a display device comprising a box body, a switch and a display screen installed in the front of the box body, and the switch and the display screen are electrically connected so that the condition of the affected area can be displayed on the display screen. A circular groove is opened on one side of the upper side of the box body, and a blind hole is opened below the circular groove so that the camera device can be placed in the blind hole for storage when not in use. A handle is installed on the base so that the camera device can be placed on the table when it is ready for use.

[0038] Compared with the prior art, the present invention has the following beneficial effects: 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 mutual cooperation between the various components within the three-dimensional reciprocating sampling and detection mechanism, the detection and sampling process of the auxiliary diagnostic device is optimized. The circular motion structure design between the various components within the mobile sampling top box allows the movement trajectory of the central sampling lens and the macro sampling lens to approach the contour shape of the patient's skin, thereby effectively preventing image distortion during the sampling process of the auxiliary diagnostic device and improving the overall sampling accuracy of the auxiliary diagnostic device. At the same time, the pressure sensor and sampling lens can collect and sample the hardness and deep internal structure of the lesion area, thereby effectively expanding the types of parameters that the auxiliary diagnostic device can detect and sample, and improving the diagnostic accuracy of the auxiliary diagnostic device;

[0040] At the same time, the structural design of the guide ring frame and the driving ring rod fixed track reduces the difficulty of debugging the equipment during use, and makes the tilt angle and point position of the center sampling lens to take pictures consistent, thereby effectively reducing the difficulty of image stitching of the auxiliary diagnostic equipment in the later stage, and effectively improving the overall use efficiency of the auxiliary diagnostic equipment. At the same time, through the cooperation of the dual-drive steering motor and the driving rubber wheel, the rotation process of the driving ring rod is smoother, thereby effectively improving the overall operation stability of the internal components of the auxiliary diagnostic equipment. At the same time, through multiple sets of fill light panels, the patient's skin is filled with light at multiple angles, thereby effectively improving the clarity of the images taken by the center sampling lens and the macro sampling lens, and further improving the overall use effect of the auxiliary diagnostic equipment.

[0041] 2. A top clamping isolation mechanism is provided. Through the interaction between the various components within the top clamping isolation mechanism, the cleaning process of the top of the auxiliary diagnostic equipment is optimized. By quickly replacing the isolation translucent paper on the top of the supporting lighting bed board, the top of the supporting lighting bed board can be quickly cleaned. This prevents debris shed by patients during the test from adhering to the top of the supporting lighting bed board and being touched by subsequent patients, thereby effectively preventing cross-infection between different patients when using the auxiliary diagnostic equipment, thereby effectively improving the overall safety of the auxiliary diagnostic equipment.

[0042] At the same time, through the mutual cooperation between the storage isolation end box and the various components connected to the cutting support narrow strip, it is ensured that the isolation translucent paper can be quickly clamped and limited during the replacement process, ensuring that the isolation translucent paper will not be randomly displaced during use, thereby effectively improving the overall replacement and installation efficiency of the isolation translucent paper, and through the cooperation between the installation inclined groove and the sealing inclined end cover, the installation rotating rod can be quickly replaced, further improving the overall convenience 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. The system combines pressure sensors and optical control technology to automatically adjust the shooting focus and light intensity according to the contact situation. It is suitable for horizontal and handheld acquisition methods, meets the requirements of contact imaging of dermatoscopes, enhances the positioning and multi-label classification capabilities of small lesions, supports embedded deployment, and combines decision trees with medical knowledge graphs to complete pathological feature extraction and rule matching. The auxiliary decision module can automatically generate structured diagnostic reports, support case similarity retrieval, drug recommendations, contraindication reminders and medical insurance comparison, and support remote revisions by doctors to achieve human-computer collaborative diagnosis and treatment. The overall system has the advantages of high diagnostic efficiency, strong adaptability, and high intelligence level. It is suitable for primary medical institutions and telemedicine scenarios, and can effectively support early screening and intelligent auxiliary diagnosis of skin diseases.

[0044] In summary, through the mutual cooperation between the three-dimensional reciprocating sampling detection mechanism and the top clamping isolation mechanism, the sampling, detection and cleaning process of the auxiliary diagnostic equipment is optimized. Through the multi-point and multi-angle shooting detection sampling of the central sampling lens and the macro sampling lens, combined shooting is performed from the whole to the part, so that medical staff can use the combined photos to quickly and accurately diagnose the partial area, distribution ratio and diffusion trend of the diseased skin on the patient's epidermis, and through the microscopic sampling of local details of the diseased area, the overall diagnostic efficiency and effect of the auxiliary diagnostic equipment are effectively improved. The overall cleanliness of the auxiliary diagnostic equipment is maintained by the rapid replacement and cleaning method, which effectively avoids the phenomenon of cross infection of patients in the process of using the auxiliary diagnostic equipment and improves the overall safety of the auxiliary diagnostic equipment.

[0087] Combining the drug knowledge base with the clinical pathway rule engine, a recommended list of medications is generated for specific diseases, covering topical medications, systemic medications, and contraindications, and supporting drug linkage query and comparison with the medical insurance catalog.

[0088] A manual review channel is reserved to allow dermatologists to remotely view diagnosis details and add revision suggestions, which is compatible with the "human-computer collaboration" diagnosis scenario.

[0089] The working principle and use process of the present invention: During the actual application of the present invention, when it is necessary to use auxiliary diagnostic equipment to diagnose and detect the patient's skin, the supporting lighting bed board 2 and the front control seat 3 are assembled and installed through the rectangular mounting base 1, and then the patient is made to lie flat on the top surface of the supporting lighting bed board 2. When it is necessary to shoot and sample the lesion area on the patient's skin, the horizontal driving screw rod 403 is driven to rotate by driving the translation motor 402, and during the rotation of the horizontal driving screw rod 403, the driving translation slider 404 is driven to slide horizontally along the inside of the limiting guide rectangular groove 401, and the sliding of the driving translation slider 404 is driven to drive the guide ring frame 405 and the components thereon to move synchronously, and the movement of the guide ring frame 405 drives the driving ring rod 406 and the mobile sampling top box 407 to move horizontally. During the movement of the mobile sampling top box 407, the central sampling lens 408 is used to shoot the overall distribution of the lesion area on the outside of the patient's skin, so as to analyze and record the proportion and distribution area of the lesion area on the patient's skin;

[0090] When it is necessary to take a fixed-point sample of the patient's skin, after the guide ring frame 405 is translated to a suitable position by driving the translation motor 402, the driving steering motor 414 installed on the side of the inclined plate 413 drives the driving rubber wheel 415 to rotate, and in the process of rotating the driving rubber wheel 415, the driving ring rod 406 is driven to rotate along the inside of the guide ring frame 405, and in the process of rotating the driving ring rod 406, the mobile sampling top box 407 is driven to deflect to the direction where sampling is required, and then the corresponding electric telescopic driving rod 409 is started to drive the pressure sensor 410 to extend toward the patient's skin, and the distance between the patient's skin and the mobile sampling top box 407 and the hardness of the skin are sampled and detected by the pressure sensor 410, and then the surface features of the skin at the lesion are photographed and sampled by the macro sampling lens 411, and then the deep features of the skin at the lesion are deep sampled by the sampling lens 412;

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

[0092] At the same time, when sampling the patient's diseased skin, the fill light board 417 can be installed on the inner side of the guide ring frame 405 by installing the arc plate 416, and the fill light board 417 is used to fill light at the shooting location, thereby effectively improving the clarity of the shooting location, and the inner side of the guide ring frame 405 is auxiliary supported by the limit 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 diagnosis equipment.

[0093] When the top surface of the supporting lighting bed board 2 needs to be cleaned after completing a single test, the used isolation light-transmitting paper 508 laid on the top of the supporting lighting bed board 2 is cut off by a cutting tool in conjunction with the cutting support narrow strip 512, and then the limiting pressing round block 511 is swung upward to cancel the limiting of the isolation light-transmitting paper 508 on the top of the supporting lighting bed board 2, and the isolation light-transmitting paper 508 is removed as a whole to achieve cleaning of the top of the supporting lighting bed board 2;

[0094] When it is necessary to replace the new isolation translucent paper 508, the installation rotating rod 505 is installed inside the storage isolation end box 502 by installing the inclined groove 503, and the side of the storage isolation end box 502 is isolated and protected by the sealing inclined end cover 504. Then the cleaning staff pulls the new isolation translucent paper 508 from the outside of the storage cylinder 507 and lays it on the top surface of the supporting lighting bed board 2, and then drives the limiting and pressing circle 511 to swing through the deflection swing box 509 and the telescopic swing rod 510, and during the swinging process of the limiting and pressing circle 511, it is clamped to the inside of the pressing and limiting slot 501, and then the isolation translucent paper 508 is pressed and limited by the cooperation between the pressing and limiting slot 501 and the limiting and pressing circle 511, thereby realizing the replacement of the isolation translucent paper 508 and preventing the isolation translucent paper 508 from displacement and slippage during use.
