Abstract
A surgical assembly is disclosed. The assembly has a cannula. The cannula has an oblong opening on a proximal end, one or more textured features on an outside, and a stabilizer at the proximal end. The assembly also has an obturator sized to fit within the cannula from the proximal end of the cannula. The obturator has a tapered end configured to extend from the distal end of the cannula and a protrusion on a proximal end of the obturator configured to engage a portion of the cannula.
