[0032] See also Figure 1 , Figure 3 and Figure 4 The bottom end of the supporting telescopic rod 7 is fixedly connected with a hose 3, and the bottom end of the hose 3 is slidably connected with a sealing box 2 ， To achieve water connectivity, the interior of the sealed box 2 is fixedly connected to a water storage box 14, and the outer wall of the hose 3 is fixedly connected to a water pump 13. ， To realize water extraction, a water pipe 12 is fixedly connected inside the supporting telescopic rod 7, the water pipe 12 is communicated with the hose 3, the top of the water pipe 12 is fixedly connected with a telescopic water pipe 8, the top of the telescopic water pipe 8 is fixedly connected to one side of the supporting telescopic rod 7, and the telescopic support rod 7 is telescoped. 通 Through the cooperation of the sealing box 2, the hose 3, the water pump 13 and the water storage box 14, water is pumped into the water pipe 12, and the expansion and contraction of the supporting telescopic rod 7 is achieved through the cooperation of the supporting telescopic rod 7, the water pipe 12 and the water pump 13, thereby improving the flexibility of the single-hole chest cavity that is easy to fix.

[0033] See also Figure 2 , Figure 5 and Figure 6A water storage box 14 is provided on the top of the supporting telescopic rod 7, and a rubber ring is fixedly connected inside the water storage box 14 to strengthen the connection with subsequent parts. A connecting tube 19 is fixedly connected to one side of the connecting rod 9, and a sliding block 20 is slidably connected inside the connecting tube 19. One end of the sliding block 20 is slidably connected to two groups of elastic telescopic rods 11, and one end of the elastic telescopic rod 11 away from the sliding block 20 is fixedly connected to the inner wall of the connecting rod 9. 实 The extension and retraction of the sliding block 20 is realized. The sliding block 20 is located on one side of the connecting rod 9 and is rotatably connected to the synchronization rod 21. The synchronization rod 21 is rotatably connected to the plug-in rod 15. The plug-in rod 15 slides on the top of the connecting rod 9, thereby realizing the linkage between the plug-in rod 15 and the sliding block 20. The extension and retraction of the elastic telescopic rod 11 is realized through the cooperation of the connecting rod 9, the connecting tube 19 and the sliding block 20. The lifting of the synchronization rod 21 is realized through the cooperation of the sliding block 20 and the synchronization rod 21. The loading and unloading of the connecting rod 9 is realized through the cooperation of the water storage box 14 and the plug-in rod 15, thereby improving the service life.

[0034] Working principle: First, when the angle of the connecting rod 9 needs to be adjusted, the gear 10 is driven to rotate by rotating the supporting telescopic rod 7, and the telescopic rod 4 is adjusted to retract inwardly through the teeth of the gear 10, so that the gear 10 can rotate smoothly. When the gear 10 stops rotating, the elastic force of the adjusting spring 5 is adjusted to make the telescopic rod 4 and the gear 10 tightly mesh, thereby achieving the limitation of the supporting telescopic rod 7, so that the connecting rod 9 can work normally through the high-power camera 16, the reflector 17 and the light source 18 to illuminate the patient's internal organs, which avoids the situation where the doctor needs to hold it for a long time, thereby improving the practicality of this single-port thoracoscope that is easy to fix.

[0035] Secondly, when it is necessary to adjust the length of the supporting telescopic rod 7, start the water pump 13 to pump water from the inside of the water storage box 14 to the inside of the water pipe 12 through the hose 3, and then expand the supporting telescopic rod 7 to promote the extension of the supporting telescopic rod 7. When it is necessary to shrink the supporting telescopic rod 7, the water inside the water pipe 12 is pumped out by the water pump 13 to shrink the supporting telescopic rod 7, thereby adjusting the length of the supporting telescopic rod 7.

[0036] Finally, when the connecting rod 9 needs to be removed for cleaning, the sliding block 20 is squeezed to move the synchronization rod 21, thereby driving the plug-in rod 15 to descend and detach from the inside of the water storage box 14, thereby realizing the removal of the connecting rod 9. When the cleaning and installation are completed, the sliding block 20 is squeezed to place the top of the connecting rod 9 into the hole at the top of the supporting telescopic rod 7, and then the sliding block 20 is released to allow the elastic telescopic rod 11 to drive the plug-in rod 15 to reset and insert it into the inside of the water storage box 14, and then the rubber ring inside the water storage box 14 is used to reinforce the plug-in, thereby increasing the service life.
