Laparoscopic instrument and trocar systems and related surgical method
First Claim
1. A trocar unit comprising:
- a flexible lateral wall defining a cavity, a distal portion of which forms a surgical site, the cavity having a proximal end and an open distal end;
a flexible first plate configured to connect to a proximal portion of the flexible lateral wall;
a second plate configured to fit securely within a portion of the flexible lateral wall and disposed distally with respect to the flexible first plate;
a plurality of independent portals extending through at least said flexible first plate,at least one of said independent portals extending through said flexible first plate in a direction transverse to said flexible first plate,said portals being configured and dimensioned for simultaneous accommodation of surgical instrumentation;
the flexible first plate further includes a flexible connector configured to attach to the flexible lateral wall,said flexible first plate configured to be positioned above an opening at the surgical site.

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 unit comprising:
-
a flexible sleeve having a proximal portion and an open distal portion having a space forming at least a portion of a surgical site; an upper horizontal plate defining a first plane and having a fixed diameter; a plurality of independent portals extending through said upper horizontal plate, said independent portals being configured and dimensioned for simultaneous accommodation of surgical instrumentation; a second horizontal plate defining a second plane and spaced distally from the upper horizontal plate; a flexible lateral wall extending distally from the upper horizontal plate, the flexible lateral wall capable of forming multiple diameters; wherein a portion of the flexible lateral wall is configured and dimensioned to form a seal with tissue such that at least a diameter of the multiple diameters of the flexible lateral wall is less than the fixed diameter of the upper horizontal plate. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
