[0025] In summary, when the multifunctional visual urinary tract treatment and inspection dilator is used, the front end of the device is inserted into the patient's urinary tract. When a section of the urinary tract is narrowed due to hyperplasia or the like, the front end of the dilation tube 3 is passed through this section, and then a set of driving components are operated to allow the gas inside the second piston chamber 23 to enter the fifth pipe 30 and the fourth pipe 20, and then enter the first annular chamber 19 through the fourth pipe 20, so that the gas inside the first annular chamber 19 enters the second support airbag 12 through the hose 16, so that the second support airbag 12 expands, and the gas inside the fifth pipe 30 enters the first pipe 10 through the second annular chamber 29, and then enters the first pipe 10 through the first pipe 10. Enter the first support airbag 9 to expand the first support airbag 9, so that the first support airbag 9 and the second support airbag 12 are in contact with the urethral wall, and this section of the area is propped up, so that the image of this section of the area can be collected through the camera 5, and the treatment and sampling operations are performed through the operation window 4. When it is necessary to adjust the support position of the second support airbag 12, by closing the switch valve at one end of the fifth pipeline 30, and then the driving component works, the gas inside the second support airbag 12 is extracted through the fourth pipeline 20, the first annular cavity 19 and the hose 16, so that the second support airbag 12 shrinks, and the gas is sucked into the second piston cavity 23 through the fourth pipeline 20, and then another set of driving components works, so that the gas inside the second support airbag 12 is sucked into the second piston cavity 23 through the fourth pipeline 20. The gas in the second piston chamber 23 on the left side of the second piston column 25 enters into the first piston chamber 14 and is located in the right chamber of the first piston column 15 through the third pipe 18. At the same time, the gas in the first piston chamber 14 and located in the left chamber of the first piston column 15 is sucked into the second piston chamber 23 and is located in the right chamber of the second piston column 25 through the second pipe 17, so that the first piston column 15 pushes the mounting sleeve 11 and the second supporting airbag 12 to move, and adjusts the position of the second supporting airbag 12, so that the driving component can be driven to work, so that the gas in the driving groove 22 and located in the left chamber of the second piston column 25 enters into the first piston chamber 14 and is located in the first piston column 1 through the second pipe 17. 5, the gas inside the first piston chamber 14 and located in the left chamber of the first piston column 15 is sucked into the second piston chamber 23 and located in the right chamber of the second piston column 25 through the third pipe 18, so that the first piston column 15 drives the mounting sleeve 11 and the second support airbag 12 to reset and move, and then when the second support airbag 12 is moved to the required position, the driving component is started, and gas is input into the fourth pipe 20, so that the gas enters the first annular chamber 19 through the fourth pipe 20, and then enters the hose 16 through the first annular chamber 19, and then enters the second support airbag 12 through the hose 16, so that the second support airbag 12 expands and limits the position of the outer tube 6; Then the electromagnet 43 is turned off, so that the magnetic attraction between the electromagnet 43 and the magnetic block 45 disappears, so that the fixing seat 21 is disconnected from the outer tube 6 and the connecting end 1. At this time, the outer tube 6 and the rotating tube 7 are located in the patient's urethra. Then the connecting end 1 can be moved, the position of the expansion tube 3 can be rotated, and the expansion tube 3 can be rotated so that the image of this section area can be collected through the camera 5, and the treatment and sampling operations can be performed through the operation window 4. When it is necessary to rotate the operation port 8, the switch valve at one end of the fourth pipeline 20 is closed, and the switch valve at one end of the fifth pipeline 30 is opened. By driving The driving assembly allows the gas inside the first support airbag 9 to enter the second annular cavity 29 through the first pipe 10, and then be discharged into the second piston cavity 23 through the fifth pipe 30, so that the first support airbag 9 shrinks, and the limit of the rotating tube 7 is released. The remaining set of driving assemblies is driven to start the driving assembly, so that the gas inside the second piston cavity 23 enters the third airbag 40 through the sixth pipe 42, so that the third airbag 40 expands and pushes the telescopic column 39 and the rack 44 to move, so that the rack 44 can drive the transmission gear 35 and the one-way bearing to move. The worm 33 rotates, so that the worm 33 drives the worm wheel 34 to rotate, so that the worm wheel 34 drives the support rod 32 to rotate, so that the support rod 32 drives the driving gear 36 to rotate, so that the driving gear 36 drives the ring gear 37 to rotate, so that the ring gear 37 drives the rotating tube 7 to rotate, and the position of the operating port 8 on the rotating tube 7 is adjusted. As the driving assembly works, the gas inside the third airbag 40 is sucked into the second piston chamber 23 through the sixth pipe 42, so that the sixth pipe 42 contracts. At this time, the reset spring 41 pushes the telescopic column 39 to drive the rack 44 to reset and move, so that the rack 4 The telescopic cylinder 38 cannot be driven to rotate through the transmission gear 35 and the one-way bearing, and the gear ring 37 and the rotating tube 7 cannot be driven to rotate. The rotating tube 7 drives the operating port 8 to rotate to the required position, and then the driving assembly is started, so that the gas inside the second piston chamber 23 enters the second annular chamber 29 through the fifth pipeline 30, and then enters the first supporting airbag 9 through the first pipeline 10, so that the first supporting airbag 9 expands and is limited again, so as to limit the rotating tube 7, and then image acquisition, treatment and sampling operations are performed; When not in use, the connecting end 1 and the expansion tube 3 are pushed into the designated position, so that the connecting end 1 drives the magnetic block 45 to trigger the trigger switch 46. At this time, the electromagnet 43 is started, so that a magnetic attraction force is generated between the electromagnet 43 and the magnetic block 45, and the fixing seat 21 is connected with the outer tube 6 and the connecting end 1. Then, the second supporting airbag 12 and the first supporting airbag 9 are contracted through the driving component, and the limit of the outer tube 6 and the rotating tube 7 are released, so that the expansion tube 3, the outer tube 6 and the rotating tube 7 can be taken out of the urethra; The camera 5 can be used to take image samples of the inside of the urinary tract and the prostate in order to make corresponding diagnoses. The doctor can extend the sampling forceps through the operating window 4 to take samples from the inside of the urinary tract and the prostate for inspection. The probes of infrared, ultrasonic, ultraviolet and other therapeutic instruments can also be installed in the operating window 4 so as to implement treatment on the patient's urinary tract and prostate according to treatment needs.
