Abstract
Two part laparoscopic tools and surgical methods using such tools are presented. The tools and methods enable use of multiple surgical tools each having wide tool heads to be used in a body cavity using a single wide trocar and one or more narrow incisions, thereby reducing surgical risk and enhancing patient comfort and shortening recovery time. Additional instruments for facilitating laparoscopic surgery are also presented.
