This invention relates to the field of medical device technology, specifically to a tissue protection shielding device for laparoscopic surgery. The device includes a shielding assembly and a pull cord. The shielding assembly comprises several shielding plates; each shielding plate has a perforation, and an elastic element connects adjacent shielding plates.
