Abstract

Trocar for instrument access to body cavities in minimally invasive surgery, the trocar comprising: - a body having a first access opening and at least one second access opening, each for inserting an instrument; - a cannula arranged with a proximal end to the body and having a distal end suitable for insertion into body cavities in minimally invasive surgery, wherein the cannula has a substantially constant out of round cross-section along is length, wherein a channel in the cannula is connected to the first access opening to provide a first passageway for an instrument and to the second access opening to provide at least one second passageway separate from said first passageway; and - a gas inlet arranged at the body and in fluid connection with the at least one passageway for inflating the body cavity with a gas, such as carbon dioxide gas.
