Abstract
Laparoscopic instruments and cannulas are provided for performing laparoscopic procedures entirely through the umbilicus. Generally S-shaped laparoscopic instruments placed through the C-shaped trocar sleeves or through the cannula and instrument holder unit provide markedly improved degrees of instruments' freedom during trans-umbilical laparoscopic procedures.
