Abstract
An integral seal system includes a body that defines a central opening, and an asymmetric seal extending into the central opening and including a diaphragm and an annular flange that extends between the body and the diaphragm, wherein the diaphragm has a cross-sectional thickness larger than a cross-sectional thickness of the annular flange. A duckbill seal extends distally from a bottom of the body and defines one or more parting lines that separate opposing seal flaps. The diaphragm complements insertion and extraction drag forces generated by the duckbill seal against a surgical tool shaft extended therethrough such that total insertion and extraction drag forces generated by the integral seal system are equalized.
