摘要:
The present disclosure relates to a surgical access system that includes a cannula assembly adapted for removable positioning within a percutaneous tissue tract, and an obturator assembly removably positionable within the cannula assembly. The cannula assembly includes a cannula housing, a cannula sleeve, and first engagement structure, and the obturator assembly includes an obturator housing, an obturator sleeve, and second engagement structure. The first engagement structure and the second engagement structure are correspondingly dimensioned such that rotation of the obturator assembly in a first direction effectuates corresponding rotation of the cannula assembly to facilitate advancement of the cannula assembly through tissue.
