A tool for the induction of the pneumoperitoneum comprises a bowl- shaped element (11, 111) having an open end edge (12, 112) adapted to adhere with the skin of a patient at the abdominal wall, the bowl-shaped element (11, 111) having an outer surface (13, 113), an inner surface (15, 115) and at least one hole (14, 114) with an inner diameter (&phgr;) at least equal to the outer diameter (de) of the needle (2) used in combination, for the passage thereof. The bowl-shaped element (11, 111) is made of an elastically yieldable material to elastically deform and move, in response to a pressure exerted by an operator on its outer surface (13, 113), from an undeformed condition wherein the inner surface (15, 115) is spaced apart from the skin to a deformed condition wherein the inner surface (15, 115) is close to the abdominal wall or in at least partial contact therewith to produce an at least partial vacuum upon its elastic return in the undeformed condition, for lifting the abdominal wall. |
