Laparoscopic instrument and trocar systems for trans-umbilical laparoscopic surgery
First Claim
1. A trocar holder for holding multiple spaced-apart trocars comprising:
- a flexible sleeve defining a portion of a surgical site;
an upper surface;
a separate lower surface spaced from and disposed below said upper surface; and
an outer wall connected between said upper surface and said lower surface, said outer wall defining a cavity, a distal portion of which forms a portion of the surgical site, at least one passageway defined by said upper surface, said lower surface and said outer wall, the trocar holder upper surface having multiple space-apart openings configured to enable multiple trocars to be disposed through said upper surface, and wherein at least one of said trocars has a straight configuration.

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.

12. A trocar holder for holding multiple spaced-apart trocars comprising:
-
a flexible sleeve defining a portion of a surgical site, said flexible sleeve having a proximal portion and an open distal portion defining a cavity therein, said distal portion forming the portion of the surgical site; an upper surface; a separate lower surface spaced from and disposed below said upper surface; and an outer wall connected between said upper surface and said lower surface, at least one passageway defined by said upper surface, said lower surface and said outer wall, the trocar holder upper surface having multiple spaced-apart openings configured to enable multiple trocars to be disposed through said upper surface, and wherein at least one of said trocars has a straight configuration, and wherein the at least one of said trocars having a straight configuration is at least partially disposed, at said upper surface, through said at least one passageway. - View Dependent Claims (13, 14, 15, 16)
