[0029] Working principle: When in use, during laparoscopic surgery, after the sleeve 104 is inserted into the abdominal cavity, when dual-mode imaging is required, the imaging head 103 and the catheter 102 are inserted into the fixed ring 12 through the annular cover 14, and then the electromagnet 404 is powered off. At this time, under the action of the first spring 502, the movable plate 406 slides downward along the side wall of the guide rod 501, and the movable rod 204 is driven by the telescopic mechanism 6 to slide downward along the fixed tube 202, so that the gas temporarily stored in the fixed tube 202 can be squeezed and enter the annular cover 14 through the inflation tube 203, so that the airbag 16 can be inflated and abut against the side wall of the catheter 102 to form a sealing effect; When the airbag 16 reaches a certain pressure, when the moving plate 406 continues to move downward, the second spring 603 is gradually compressed. At the same time, it can drive the pushing block 1002 to slide downward along the inclined surface 1001.

At the same time, the third spring 704 is compressed, and the through hole 303 is aligned with the air supply pipe 17. At this time, under the gravity of the counterweight 21, the carbon dioxide gas in the gas storage cover 18 can pass through the air supply pipe 17 and the through hole 303 and then enter the fixed ring 12 and the abdominal cavity, and the pressure can be kept constant. Then, the imaging head 103 and the catheter 102 can be extended into the human body through the sleeve 104 to perform dual-mode imaging to ensure the imaging effect. After the operation is completed, the electromagnet 404 is energized. After being energized, the electromagnet 404 attracts the iron block 405, so that the movable plate 406 moves upward along the guide rod 501. At the same time, the first spring 502 is compressed. When the movable plate 406 gradually separates from the inclined surface 1001, the sliding plate 302 can move and reset under the action of the third spring 704, so that the through hole 303 and the air supply pipe 17 are offset, so that the air supply pipe 17 is blocked and sealed by the sliding plate 302. When the movable plate 406 continues to move upward, the telescopic mechanism 6 can drive the movable rod 204 to move upward and reset, so that the gas in the annular cover 14 can be drawn back into the fixed tube 202, so that the airbag 16 shrinks and resets, thereby facilitating the removal of the imaging head 103 and the catheter 102.
