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

1-27. -27. (canceled)

28. A cannula holder for holding multiple spaced-apart cannulas comprising:

an upper surface;

a lower surface 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 cannula holder being configured to enable multiple spaced-apart cannulas to be disposed through said upper surface, and

wherein at least one of said cannulas has a straight configuration.

29. The cannula holder as in claim 28, wherein the at least one of said cannulas having a straight configuration is at least partially disposed, at said upper surface, through said at least one passageway.

30. The cannula holder as in claim 28, wherein the at least one passageway is formed by resilient material.

31. The cannula holder as in claim 30, wherein the at least one passageway extends from the upper surface to the lower surface.

32. The cannula holder as in claim 28, wherein the outer wall is configured and dimensioned to be positioned within a surgical incision in a subject.

33. The cannula holder as in claim 32, wherein said lower surface cooperates with said outer wall to seal the upper surface in position with respect to the surgical incision in the subject.

34. The cannula holder as in claim 33, wherein the upper surface, the outer wall and the lower surface together define a working access for surgical instruments positioned in said cannulas.

35. The cannula holder as in claim 34, wherein at least the lateral wall is deformable between a first position for insertion into a surgical incision and a second position in sealing contact with the surgical incision.

36. The cannula holder as in claim 28, wherein the cannulas have a proximal portion and a distal portion and wherein the proximal portion extends proximally of the upper surface.

37. The cannula holder as in claim 28, wherein the outer wall is capable of forming multiple diameters wherein the cannula holder is deformable from a pre-insertion configuration into a sealing configuration such that the diameter of the outer wall is less than the diameter of the upper surface.

38. The cannula holder as in claim 37, wherein the minimum diameter of the outer wall conforms to a minimum diameter of a surgical incision into which the cannula holder is inserted.

39. The cannula holder as in claim 37, wherein when the cannula holder is in a non-deformed configuration, the lower surface is substantially parallel to the upper surface.

40. The cannula holder as in claim 37, wherein when the cannula holder is in a deformed configuration, the distance between the lower surface and the upper surface is reduced.

41. The cannula holder as in claim 37, wherein when the distance between the lower surface and the upper surface is reduced, the cannula holder is in a deformed configuration that facilitates insertion of the lower surface through the surgical incision.

42. The cannula holder as in claim 28, wherein the cannula holder is configured such the at least one passageway enables the spaced apart multiple cannulas to be inserted into the at least one passageway prior to insertion of the lower surface in a surgical incision of a subject.

43. The cannula holder as in claim 28, wherein the cannula holder is configured such the at least one passageway enables the spaced apart multiple cannulas to be inserted into the at least one passageway after insertion of the lower surface in a surgical incision of a subject.

44. A cannula holder for holding multiple spaced-apart cannulas comprising:

an upper surface;

a lower surface 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 cannula holder being configured to enable multiple spaced-apart cannulas to be disposed through said upper surface, and

wherein at least one of said cannulas has a straight configuration, and

wherein the at least one of said cannulas having a straight configuration is at least partially disposed, at said upper surface, through said at least one passageway.

45. The cannula holder as in claim 44, wherein the at least one passageway is formed by resilient material.

46. The cannula holder as in claim 45, wherein the at least one passageway extends from the upper surface to the lower surface.

47. The cannula holder as in claim 44, wherein the outer wall is configured and dimensioned to be positioned within a surgical incision in a subject.

48. The cannula holder as in claim 47, wherein said lower surface cooperates with said outer wall to seal the upper surface in position with respect to the surgical incision in the subject.
