Abstract
A method of surgery includes positioning a cannula within an opening in tissue and inserting a guide member into the cannula. The cannula includes an elongated portion having a base and an elongated tubular member extending distally from the base. The elongated tubular member includes an annular wall defining a longitudinal passageway. At least one slot extends through the annular wall and is disposed in communication with the longitudinal passageway. The guide member includes a guide housing and an elongated guide shaft. The guide member defines at least one lumen extending therethrough. The method further includes releasably engaging the guide housing with the base. Upon engagement of the guide housing with the base, the at least one lumen is aligned with the at least one slot to define a guide passageway through the guide member and cannula.
