Abstract
A surgical access system includes a cannula, a mapping spacer, and a trocar. The cannula includes a proximal base and an elongated cannula body extending distally therefrom. The mapping spacer is configured to releasably engage the proximal base and includes first and second uprights defining a slot therebetween. The trocar includes a proximal handle and an elongated trocar body extending distally therefrom to a distal cutting tip. The elongated trocar body is insertable through the mapping spacer and cannula. In a first orientation of the trocar relative to the mapping spacer, the proximal handle is configured to abut the first and second uprights to inhibit extension of the distal cutting tip from the proximal base beyond an initial position. In a second orientation of the trocar, the proximal handle is slidable through the slot to enable extension of the distal cutting tip distally towards an extended position.
