摘要：
A trocar which is particularly suited for use as a thoracic trocar. The trocar includes a number of arms at the distal end which are movable from a closed position, which is used for inserting the trocar into the patient, to a second position, which is used for locking the trocar to the patient. The arms may be naturally biased to the open position or may be moved by mechanical actuation.
