Laparoscopic instrument and trocar systems for trans-umbilical laparoscopic surgery
First Claim
1. A trocar holder comprising:
- a horizontal upper plate;
a lower plate spaced from the upper plate;
a plurality of independent trocars extending through said horizontal upper plate and said lower plate in a direction substantially transverse to said horizontal upper plate, said trocars being configured and dimensioned for simultaneous accommodation of surgical instrumentation; and
sealing structure for sealing the horizontal upper plate within a surgical incision such that said horizontal upper plate is positioned above the surgical incision, said sealing structure including a flexible lateral wall which at least partially defines a surgical space adjacent a distal end thereof.

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.

8. A trocar holder comprising:
-
an upper circumferential plate defining a first plane and having a fixed diameter; a plurality of independent trocars extending through said upper plate, said trocars being configured and dimensioned for simultaneous accommodation of surgical instrumentation; a lower plate spaced from said upper plate and defining a second plane; and a flexible lateral wall extending between the upper plate and the lower plate, the flexible lateral wall capable of forming multiple diameters such that a diameter of the multiple diameters of the flexible lateral wall is less than the diameter of the upper plate and the second plane being substantially parallel to said first plane, the flexible lateral wall at least partially defining a surgical space adjacent a distal end thereof, wherein the trocar holder is deformable into a sealing portion. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
