Claim 9:
10. A surgical access system, comprising:
a tubular body having a distal end and a proximal end spaced from the distal end in a proximal direction, the tubular body having an inner surface and an outer surface opposite each other along a radial direction that is perpendicular to the proximal direction, the inner surface defining a channel extending from the proximal end to the distal end in a distal direction opposite the proximal direction; and
a control member having a first end and a second end opposite one another, the control member defining a handle portion at the first end, a mounting formation at the second end, and a central bore extending through the handle portion and the mounting formation from the first end to the second end, the central bore configured to receive a first instrumentation, wherein the mounting formation is configured to mount to the proximal end of the tubular body, the mounting formation including:
an insertion portion that is configured to reside within the channel when the control member is mounted to the tubular body, the insertion portion having an outer surface, a first portion of the outer surface of the insertion portion defining a part of a cylinder and defining a major diameter of the insertion portion; and
a lip defining an inner lip surface that is opposed to the first portion of the outer surface of the insertion portion so as to define a receptacle therebetween along the radial direction, wherein the receptacle is configured to receive the proximal end of the tubular body such that the mounting formation interlocks with the tubular body and the handle portion extends from the proximal end of the tubular body in the proximal direction,
wherein a second portion of the outer surface of the insertion portion defines at least a portion of an exterior access surface, wherein the second portion of the outer surface of the insertion portion is substantially planar and defines a minor distance of the insertion portion along the radial direction, wherein the minor distance is less than the major diameter such that the at least a portion of the exterior access surface is configured to at least partially define an access opening into the channel between the second portion of the outer surface of the insertion portion and the inner surface of the tubular body when the insertion portion resides within the channel and the first portion of the outer surface of the insertion portion engages the inner surface of the tubular body.
