Abstract:
Laparoscopic instruments and trocars are provided for performing laparoscopic procedures entirely through the umbilicus. A generally C-shaped trocar provides increased work space between the hands of the surgeon as well as S-shaped laparoscopic instruments placed through the trocar when laparoscopic instrument-trocar units are placed through the umbilicus. In order to facilitate retraction of intra-abdominal structures during a laparoscopic procedure, an angulated needle and thread with either one- or two sharp ends is provided. Alternatively, an inflatable unit having at least one generally C-shaped trocar incorporated within the unit's walls can be placed through the umbilicus following a single incision. Generally S-shaped laparoscopic instruments may be placed through the generally C-shaped trocars to facilitate access to intra-abdominal structures.
