The specific embodiment

Further set forth the present invention below in conjunction with Figure of description, and provide embodiments of the invention.

Conductor like Fig. 1, this laparoscopic surgery perforator shown in 2; Constitute with inner push-rod 11 by outer guide wire 12; Described outer guide wire 12 has a tubaeform upper shed, and the bottom is asymmetric domatic opening, and outside said, is equipped with a top-down guide groove 15 on guide wire 12 outer walls.

Described guide groove 15 tops are tapered inlet, bottom notch and outer guide wire 12 domatic open pointed tip positions symmetry.

Described outer guide wire 12 is the metal body, or for nonmetal body.

Described outer guide wire 12 bottom domatic openings are the cutting edge shape.
