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.

Claims

1. A laparoseopic surgical device comprising:

a trocar holder for receiving trocars, said trocar holder having;

a flexible perimetric wall;

said flexible perimetric wall having a longitudinal axis and at least one open end traversed by said longitudinal axis,

said first transverse member connected at its perimeter to said flexible perimetric wall,

said first transverse member extending generally transversely to said longitudinal axis,

said first transverse member being spaced from said open end of said flexible perimetric wall,

said first transverse member having a plurality of trocars being spaced from one another; and

a second transverse member positioned distally relative to the first transverse member,

the plurality of trocars extending through at least the first transverse member.

2. The surgical device of claim 1, wherein said trocar holder is inflatable.

3. The surgical device of claim 1, wherein the open end of the flexible perimetric wall is located at the distal end of the flexible perimetric wall.

4. The surgical device of claim 1, wherein the first transverse member is located below a proximal end of the perimetric wall.

5. The surgical device of claim 1, wherein the first transverse member includes rigid sections inserted or attached around a periphery of the first transverse member.

6. A laparoscopic surgical device comprising:

a trocar holder for receiving trocars, said trocar holder having;

a flexible perimetric wall;

a first transverse member comprising a plate member;

said flexible perimetric wall having a longitudinal axis and at least one open end traversed by said longitudinal axis,

said first transverse member connected at its perimeter to said flexible perimetric wall,

said first transverse member extending generally transversely to said longitudinal axis,

said first transverse member being spaced from said end of said flexible perimetric wall,

said first transverse member having a plurality of trocars being spaced from one another; and

a second transverse member positioned distally relative to the first transverse member,

the plurality of trocars extending through at least the first transverse member.

7. The surgical device of claim 6, wherein the first transverse member is concave.

8. The surgical device of claim 6, wherein the first transverse member is flexible.

9. The surgical device of claim 6, wherein the first transverse member is plastic.

10. A laparoscopic surgical device comprising:
