Abstract
A trocar employing an internal stabilizer and an optional external stabilizer is provided. The internal stabilizer is passed through the tissue wall along with the cannula, with the internal stabilizer in a retracted position. Once the cannula has been extended into the anatomical cavity, the stabilizer returns to its normal, extended position. Movement of the stabilizer between its retracted and extended positions is effected by advancement and retraction of the obturator. A method of inserting the trocar cannula is also provided.
