Abstract

A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity is adapted to tissues having different thicknesses. The surgical apparatus is configured to have different lengths. In one embodiment, the surgical includes a seal anchor member having two ends, and one of which is adapted to fold resulting in a plurality of folded states. Each folded state corresponds to a different length of the seal anchor member. The seal anchor member includes a slot to facilitate transition within the plurality of folded states. The seal anchor member further includes an aperture and a pin configured to further facilitate transition within the plurality of folded states.

Claims

1. A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity comprising:

a seal anchor member defining a longitudinal axis and a plurality of ports extending along the longitudinal axis, each port of the plurality of ports configured to receive a surgical instrument therethrough, the seal anchor member including an inner portion and a folded portion folded over the inner portion, the inner portion and the folded portion defining a slot extending along the longitudinal axis of the seal anchor member, wherein the folded portion is movable over the inner portion along the longitudinal axis to selectively transition the seal anchor member to one of a plurality of states, each state corresponding to a different length of the seal anchor member.

2. The surgical apparatus according to claim 1, wherein at least a portion of the slot defined in the inner portion is in registration with at least a portion of the slot defined in the folded portion.

3. The surgical apparatus according to claim 1, wherein the plurality of states include a plurality of folded states.

4. The surgical apparatus according to claim 3, wherein the plurality of folded states include a maximum folded state corresponding to a minimum length of the seal anchor member.

5. The surgical apparatus according to claim 3, wherein the plurality of folded states include a minimum folded state corresponding to a maximum length of the seal anchor member.

6. The surgical apparatus according to claim 1, wherein the seal anchor member includes at least one of a foam material or a gel material.

7. The surgical apparatus according to claim 1, further comprising a guide pin secured with the folded portion, the guide pin slidably engaging the slot defined in the inner portion to transition the seal anchor member to one of the plurality of states.

8. The surgical apparatus according to claim 7, wherein the folded portion defines an aperture configured to receive the guide pin therethrough.

9. The surgical apparatus according to claim 8, wherein the aperture is in registration with at least a portion of the slot defined in the inner portion.

10. The surgical apparatus according to claim 8, wherein the aperture is disposed distal of the slot defined in the folded portion.

11. The surgical apparatus according to claim 1, wherein the seal anchor member includes a first end having a first radial dimension and a second end having a second radial dimension different from the first radial dimension.

12. The surgical apparatus according to claim 1, wherein the seal anchor member has an hourglass configuration.

13. A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, comprising:

a seal anchor member defining a central longitudinal axis, the seal anchor member including a first portion and a second portion, the first portion defining a hollow portion and the second portion defining a plurality of lumens configured for receipt of a surgical object and a first slit defined between at least a pair of lumens of the plurality of lumens, the first slit diametrically extending between peripheral portions of the second portion, the entire first slit defining a plane and extending along a length of the second portion of the seal anchor member.

14. The surgical apparatus according to claim 13, wherein the first slit is spaced apart from the plurality of lumens.

15. The surgical apparatus according to claim 13, wherein the second portion further defines a second slit defining a second plane.

16. The surgical apparatus according to claim 15, wherein the first and second slits intersect each other.

17. The surgical apparatus according to claim 13, wherein the plurality of lumens are symmetrically arranged with respect to the central longitudinal axis of the seal anchor member.
