[0010] Further, the technical scheme is that the fixed wing is provided with a fixed hole.

[0011] Further, the technical scheme is that the catheter body fixed end is communicated with a main joint.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] By setting the positioning air bag, the depth inserted according to actual needs is slid along the catheter body fixed end, when the positioning air bag slides to the suitable fixed position of the actual insertion depth of the catheter body, the positioning air bag is inflated by the external inflating device connected through the catheter joint, so that the inner wall of the positioning air bag is inflated to extrude the catheter body, thereby realizing the fixation, by adjusting the position of the positioning air bag in the catheter body fixed end, the depth of the air cutting catheter inserted according to the specific condition is realized.
