Abstract
A surgical introducer system having an outer introducer sidewall extending along a longitudinal axis from a proximal introducer end to a distal introducer end, an inner introducer sidewall extending within the outer introducer sidewall along the longitudinal axis and forming an introducer passage extending in a distal direction from a proximal passage opening at the proximal introducer end to an introducer passage end wall located proximal to the distal introducer end, and an end wall passage extending from the introducer passage end wall towards the distal introducer end. The introducer end wall passage joins the introducer end wall at one or more end wall edges defining an axial stop ring configured to contact the distal tip of a navigation probe between the probe shaft and a terminal end of the distal probe tip at a line of contact to thereby prevent movement of the navigation probe in the distal direction.
