[0056] The instrument for observing oral mucosa diseases and screening oral cancer in the present application can be applied to the oral mucosa disease examination and oral cancer screening of patients, and the use method is as follows: The instrument for observing oral mucosa diseases and screening oral cancer in the present application is in the state as shown in the accompanying drawings before use, with reference to the accompanying drawings Figure 14 , the accompanying drawings Figures 14-18 , and the accompanying drawings Figure 20At this time, the support rod 6 is stored in the groove 404, the sealing chamber 21 is in the closed state, the collection head 7 is sealed in the sealing chamber, the elastic element 192 is in the compressed state, and the fixed plate 23 is fastened to the movable plate 18. When using the device for deep visualization of oral mucosal diseases and oral cancer screening according to the embodiments of this application, the observation rod 4 is inserted into the patient's oral cavity. The first motor 16 is started via button 2, causing it to drive the third connecting shaft 15 to rotate. The third connecting shaft 15 drives the second connecting shaft 13 to rotate via the second transmission belt 14. The second connecting shaft 13 drives the first connecting shaft 11 to rotate via the first transmission belt 12. The rotation of the first connecting shaft 11 causes the connecting rod 6 and cam 10 connected to it to rotate under the drive of the first connecting shaft 11, thereby causing the connecting rod 6 to open. Simultaneously, combined with... Figure 6 and Figure 8 When the first motor 16 starts, it causes the sealed chamber 21 to rotate and open. When the cam 10 rotates, it causes the first connecting rod 17 connected to it to change position, thereby causing the movable plate 18 to rotate under the push of the first connecting rod 17. This causes the fixed plate 23, which is fastened to the movable plate 18, to disengage from the constraint of the movable plate 18. At this time, the elastic element 192 connected to the inner wall of the sleeve 191 disengages from its constraint and returns from the compressed state to its normal position. Figure 13 The original state shown allows the sleeve 191 to slide relative to the connecting rod 193, thereby allowing the collection head 7 to extend from the groove 404 on the observation rod 4. This enables the collection head 7 to extend from the groove 404 on the observation rod 4 when the spreading rod 6 is spread open, and to collect samples from the oral examination area of ​​the subject through the collection head 7. During this process, when it is necessary to rotate the direction of the observation rod 4, the second motor 26 is started by button 2. When the second motor 26 rotates, it drives the second gear 25 to rotate, causing the first gear 22 meshing with the second gear 25 to rotate, thereby causing the observation rod 4 to rotate and change its angle. At this time, since the third gear 28 is provided on the outer side of the connecting rod 193 and the actuating rod 30 that cooperates with the fourth gear 28 is provided on the inner wall of the third connecting section 403, the second connecting rod 19 rotates synchronously when the observation rod 4 rotates and changes its angle, thereby realizing the synchronous rotation of the observation rod 4 and the acquisition head 7. This avoids the acquisition head 7 not rotating when the observation rod 4 rotates, which would cause the groove 404 to damage the acquisition head 7 during rotation. When it is necessary to use the collection head 7 to collect samples, the second linkage 19 is rotated by rotating the knob 3, which drives the collection head 7 to rotate and collect the samples. Then, when the use is finished, the third motor is started by the button 2, the third motor drives the third gear 27 to rotate, the third gear 27 drives the toothed plate 24 to move, the limiting block 241 pushes the fixed plate 23 to move to the initial state, at this time, the sleeve 191 slides on the connecting rod 193 to the end of the handle, the elastic piece 192 is compressed, the second connecting rod 19 returns to the initial state, the collection head 7 is retracted into the cavity of the observation rod 4; Then, the first motor 16 is started by the button 2, the first motor 16 drives the third connecting shaft 15 to rotate, the first connecting shaft 11 rotates, the strut rod 6 and the cam 10 connected with the first connecting shaft 11 rotate, the strut rod 6 is retracted into the groove 404 and returns to the initial state, at the same time, the sealed cabin 21 is closed under the driving action of the first motor 16. Finally, when the collection head 7 needs to be replaced, the movable cover 5 on the observation rod 4 is opened, the sealed cabin 21 containing the collection head 7 is taken out of the opening, and the collection head 7 is replaced.
