Each sealing member comprises: a doughnut-shaped main body portion, the center of which has an opening and a cover portion which is arranged on the main body portion so as to cover the opening of the main body portion, and which has an insertion hole smaller than the opening of the main body portion such that a surgical instrument can be inserted into the insertion hole. The insertion hole is formed in the center of the cover portion, and the center of the cover portion is recessed toward the inside of the opening. The cover portion is elastically deformed and the insertion hole is expanded such that the center of the cover portion can be further recessed toward the inside of the opening when the surgical instrument having a diameter larger than the diameter of the insertion hole is inserted into the insertion hole.La présente invention concerne un élément détanchéité pour un trocart, qui permet linsertion dinstruments chirurgicaux ayant une diversité de diamètres, et un trocart à multiples orifices pour chirurgie laparoscopique comprenant lélément détanchéité.
