The design of the double-layer sealing ring is more conducive to blocking blood and water

[0032] Preferably, the internal fixation component 4 includes a balloon 41 whose upper end face rests against the inner surface of the patient's abdominal wall after inflation, and also includes a balloon inflation component 42 fixedly connected to the puncture device sleeve 1, one end of the balloon inflation component 42 is connected to the balloon 41 for inflating the balloon 41.

[0033] Specifically, Figure 2 , 3 As shown in Figures 5 and 6, the balloon inflation assembly 42 includes an air inlet port 421 and an air inlet tube body 422 which are ventilated and connected to each other. The air inlet tube body 422 is sleeved outside the puncture tube 1 to form an air inlet channel 6 with the puncture tube 1. The air inlet channel 6 is connected to the balloon 41.

[0034] Preferably, the balloon inflation assembly 42 also includes an air intake deflection channel 423 with an arc-shaped port for buffering airflow, reducing gas reflux and improving air intake efficiency. The air intake deflection channel 423 connects the air intake pipe port 421 and the air intake pipe body 422, and the arc-shaped port is connected to one side of the air intake pipe port 421.

[0035] Preferably, the air inlet port 421 is provided with a one-way valve to prevent gas backflow, thereby further improving the inflation efficiency of the airbag.

[0036] Furthermore, the external fixing component 3 further includes a sliding locking device 34, which is connected to the side of the fixing component body 31 away from the clearance space 5 and is used to lock the position of the fixing component body 31.

[0038] Preferably, a tightening member 7 is connected below the balloon 41 and is screwed and sealed with the outer side of the puncture device sleeve 1 for installing and fixing the internal fixing component 4.

[0039] The working principle of this embodiment is: the air inlet tube body 422 and the balloon 41 are installed outside the puncture tube 1 through the puncture tube 1 tightening member 7 to form an air inlet channel 6 located outside. After the patient's abdominal wall is cut with the puncture needle 2, the puncture tube 1 is inserted into the abdominal cavity to establish pneumoperitoneum. The balloon is inflated by the air inlet port 421 through the air inlet turning channel 423 set in the puncture tube 1, and supported upward under the patient's abdominal wall. The fixing component body 31 is adjusted to the upper part of the patient's abdominal wall and pressed on the patient's abdominal wall surface through the plane 32 and locked in position through the sliding locking device 34, thus forming an "I"-shaped structure clamping structure to fix the puncture device; the setting of the plane 32 is more patient-friendly than the prior art conical fixing seat inserted into the patient's incision, and will not compress the patient's incision.
