A multi-channel trocar developed for use in minimal-access surgery/single incision laparoscopic surgery. The trocar permits surgical access of two or more articulating laparoscopic instruments or scopes through one skin incision using a dividing membrane to separate the working channels. This allows maximal use of robotic technology and permits more degrees of freedom at the operative site. The trocar is inserted through one single skin incision, in the usual manner. The trocar relocates the fulcrum and focal point of motion to the abdominal wall when using a set of interacting and interlocking diaphragms.
