2. A method for utilizing a medical instrument during a medical procedure comprising the steps of:
providing a handle;
providing a trocar in static communication with said handle;
providing and dynamically communicating a cannula with said trocar and said handle;
providing an insufflation port at at least one of said handle and said cannula;
linearly engaging said cannula, at a locked position, with said handle by linearly displacing said cannula proximally towards said handle without exerting an external force generally transverse to said trocar and said cannula
linearly disengaging said cannula, to an unlocked position, from said handle by linearly displacing said cannula distally away from said handle without exerting an external force generally transverse to said trocar and said cannula;
prohibiting and permitting said cannula to articulate about a longitudinal axis of said trocar and relative to said handle, respectively, by linearly reciprocating said cannula, between said locked position and said unlocked position, along a linear travel path defined parallel to said longitudinal axis of said trocar; and
introducing a gas along said linear travel path through said insufflation port.
