Abstract
A surgical system comprising a cannula assembly and an obturator assembly for penetrating tissue is disclosed. A cover of the cannula assembly is mounted to a cannula housing and has a cover aperture therethrough. The cover has a trailing end face defining a predetermined geometrical configuration, at least a portion of the trailing end face is obliquely arranged relative to a longitudinal axis and terminates in, and leads toward the cover aperture to facilitate guiding of the surgical object through the cover aperture. The obturator assembly includes an obturator housing and an obturator member. The obturator housing has a housing base defining a leading end face, which defines a predetermined geometrical configuration corresponding to the predetermined geometrical configuration of the trailing end face of the cover to mate therewith upon assembly of the obturator assembly with the cannula assembly.
