In order to better understand the characteristics of the present creation, the present invention provides a preferred embodiment of the auxiliary lens visualization puncture guide set and is illustrated as follows, please refer to Figures 1 to 3. In this embodiment, the minimally invasive operation of the abdominal cavity is taken as an example. The above-mentioned puncture guide sleeve set is for an external endoscope T to extend, and the main components thereof include an outer tube 10, an inner rod 20, and a first gas. The structure of the components and the relationship between the components of the second airtight component 30 and the second airtight component 40 are as follows: First, referring to FIG. 1 and FIG. 2, the outer tube 10 is sequentially provided with a holding portion from top to bottom. 11 and the tube portion 12, and the grip portion 11 is in straight line communication with the inside of the straight tube portion 12. The outer peripheral surface of the grip portion 11 is provided with 12 anti-slip ribs 14 . The outer peripheral surface of the straight tube portion 12 protrudes to form a pressing flange 17 and is provided with an external thread 15 . The external thread 15 is from top to bottom. The system is spiraled down clockwise. The outer tube 10 further includes a gas valve 13 that communicates with the interior of the outer tube 10 and is connected to an automatic inflator (not shown). The gas valve 13 has a switch 16 to control whether the gas in the automatic inflator can be controlled. It flows to the inside of the outer tube 10.

Referring to FIG. 3, the inner rod 20 has a top portion 21 and a piercing portion 22 at the top and bottom ends of the inner rod 20, respectively. . The grip portion 11 is recessed from the center of the top surface into the puncture portion 22 to form an endoscope passage 23 for the endoscope T to pass. When the inner rod 20 is inserted into the outer tube 10, the puncture portion 22 protrudes from the bottom end of the straight tube portion 12, and the puncture portion 22 is transparent, so that the light emitted by the endoscope T can penetrate the puncture portion 22 and Receive images.

The first airtight member 30 is disposed in the outer tube 10 and is fixed to the outer tube 10. The first airtight member 30 has an opening for the inner rod 20 to pass therethrough. In this embodiment, the first airtight component 30 is a universal valve and the first airtight component 30 is made of silicone.

The second airtight member 40 is disposed in the outer tube 10 and fixed to the outer tube 10, and the second airtight element The member 40 is located below the first member and has a flat opening for the inner rod 20 to pass.
