Abstract

A surgical device including a seal anchor that includes leading and trailing portions. A plurality of ports longitudinally extends between the leading and trailing portions. The ports are adapted and configured to receive surgical objects therein. At least one of the surgical objects is a viewing instrument including a viewing portion. During a surgical procedure, surgical objects inserted in the other ports are selectively positionable with respect to the viewing instrument.

First claim

What is claimed is:

1. A surgical system comprising:
a seal anchor member for positioning within a tissue tract accessing an underlying body cavity, the seal anchor member defining a longitudinal axis and including leading and trailing ends, an intermediate section disposed between the leading and trailing ends, and a plurality of ports extending between the leading and trailing ends; and
a triangulation device including:
a rotatable member received in a first port of the plurality of ports in a sealing relation;
at least one surgical instrument configured to be received in a second port of the plurality of ports in a sealing relation; and
a linkage mechanism operably coupling the at least one surgical instrument and the rotatable member, wherein rotation of the rotatable member transitions the at least one surgical instrument between a first position in which the at least one surgical instrument is substantially parallel to the longitudinal axis of the seal anchor member and a second position in which at least a portion of the at least one surgical instrument defines an acute angle with respect to the longitudinal axis.

2. The surgical system of claim 1 , wherein the linkage mechanism includes an arm member operably coupling the at least one surgical instrument and the rotatable member.

3. The surgical system of claim 2 , wherein the linkage mechanism further includes a collar threadably coupled with the rotatable member, whereby rotation of the rotatable member causes movement of the collar along a length of the rotatable member.

4. The surgical system of claim 3 , wherein the linkage mechanism further includes a band positioned about the at least one surgical instrument, the band pivotably connected to the arm member.

5. The surgical system of claim 4 , wherein the arm member includes a first arm pivotably connected to the band and a second arm pivotably connected to the collar, the first and second arms pivotably coupled to each other.

6. The surgical system of claim 1 , wherein the at least one surgical instrument includes a weakened region configured to bend upon application of a force thereto.

7. The surgical system of claim 1 , wherein the at least one surgical instrument includes a hinge configured to bend upon application of a force thereto.

8. The surgical system of claim 1 , wherein the at least one surgical instrument is formed of a compliant material.

9. The surgical system of claim 1 , wherein the plurality of ports extend longitudinally between the leading and trailing ends of the seal anchor member.

10. The surgical system of claim 1 , wherein the triangulation device further includes a viewing portion operatively associated with the rotatable member.

11. The surgical system of claim 1 , wherein the at least one surgical instrument includes an end effector.

12. A surgical system, comprising:
a seal anchor member for positioning within a tissue tract accessing an underlying body cavity, the seal anchor member including leading and trailing ends, the seal anchor member defining a plurality of ports extending between the leading and trailing ends; and
a triangulation device including:
a rotatable member configured to be received through a first port of the plurality of ports in a sealing relation; and
at least one surgical instrument received in a second port of the plurality of ports in a sealing relation, the at least one surgical instrument operatively coupled with the rotatable member, wherein rotation of the rotatable member transitions the at least one surgical instrument between a first position in which the at least one surgical instrument is substantially parallel to a longitudinal axis defined by the rotatable member and a second position in which at least a portion of the at least one surgical instrument defines an acute angle with respect to the longitudinal axis.

13. The surgical system of claim 12 , wherein the triangulation device further includes a viewing portion operatively associated with the rotatable member.

14. The surgical system of claim 12 , wherein triangulation device further includes a linkage mechanism operably coupling the at least one surgical instrument and the rotatable member, the linkage mechanism including an arm member operably coupling the at least one surgical instrument and the viewing instrument.

15. The surgical system of claim 14 , wherein the linkage mechanism further includes a collar threadably coupled with the rotatable member, whereby rotation of the rotatable member causes movement of the collar along a length of the rotatable member.

16. The surgical system of claim 15 , wherein the linkage mechanism further includes a band positioned about the at least one surgical instrument, the band pivotably connected to the arm member.

17. The surgical system of claim 16 , wherein the arm member includes a first arm pivotably connected to the band and a second arm pivotably connected to the collar, the first and second arms pivotably coupled to each other.

18. The surgical system of claim 12 , wherein the at least one surgical instrument includes a hinge configured to bend upon application of a force thereto.

19. The surgical system of claim 12 , wherein the at least one surgical instrument is formed of a compliant material.

20. The surgical system of claim 12 , wherein at least one port of the plurality of ports extends longitudinally between the leading and trailing ends of the seal anchor member.

21. The surgical system of claim 12 , wherein the at least one surgical instrument is disposed radially about the rotatable member.

22. The surgical system of claim 12 , wherein the at least one surgical instrument includes an end effector.

23. The surgical system of claim 12 , wherein the at least one surgical instrument includes a weakened region configured to bend upon application of a force thereto.
