Abstract

Devices, tools and methods for performing minimally invasive surgical procedures. Methods of performing minimally invasive ablation procedures. Methods of performing rapid exchange of tools in a device while the device remains in a reduced-access surgical space.

First claim

That which is claimed is:

1. A surgical system for performing minimally invasive surgical procedures, said system comprising:
an elongated body having a distal end portion, a proximal end portion, an external body surface, an interior region encompassed by the external body surface, and at least a first lumen and a second lumen extending at least partially through the interior region and generally along a direction of a longitudinal axis of said elongated body, wherein the first lumen is configured for receiving an endoscope therein; and
a lens having a bullet shaped configuration forming an elongated distal tip that extends distally with respect to said distal end portion of said elongated body,
wherein the elongated distal tip comprises a curved and blunt distal end allowing for blunt dissection of tissue and a sidewall extending from a proximal end of the elongated distal tip to the curved and blunt distal end that allows for viewing of the surgical field therethrough.

2. The system of claim 1 , further comprising a handle attached to said proximal end portion of said elongated body.

3. The system of claim 2 , further comprising a bell rotatably attached to said handle, wherein said bell is rotatable relative to said handle when said system is in an operative configuration.

4. The system of claim 1 , wherein said elongated body is substantially rigid.

5. The system of claim 1 , wherein the second lumen comprises a service port adapted to receive a tool other than an endoscope.

6. The system of claim 5 , comprising two of said service ports.

7. The system of claim 5 , wherein each said service port comprises a tube received within said elongated body.

8. The system of claim 7 , wherein each said tube comprises a stainless steel hypotube.

9. The system of claim 1 , further comprising an endoscope positioned in said lumen that is configured for receiving an endoscope therein.

10. The system of claim 7 , wherein said distal tip further comprises at least one lumen therethrough, each said lumen of said distal tip being configured and dimensioned to receive one of said tubes therein and provide an exit opening for said service port through said distal tip.

11. The system of claim 1 , further comprising a seal between said lens and a portion of said distal tip proximal to said lens.

12. The system of claim 7 , wherein a proximal end portion of each said tube is securely held by a handle attached to said proximal end portion of said elongated body.

13. The system of claim 1 , wherein said lens is removably mounted to a portion of said distal tip via mechanical connection.

14. The system of claim 13 , wherein said lens is removably mounted to said portion of said distal tip via at least one of friction fitting and threads.

15. The system of claim 1 , wherein said lens is fixed to a portion of said distal tip via adhesive.

16. The system of claim 1 , wherein said distal tip is fixable to a distal end piece that includes at least one lumen, said distal end piece being mountable to said distal end portion of said elongated body, wherein said at least one lumen of said distal end piece aligns in communication with respective ones of at least one of said first and second lumens of said elongated body, in fluid communication therewith, to function as at least one service port.

17. The system of claim 1 , wherein said distal end comprises a protrusion extending distally from a distal end portion of said distal tip, said distal end portion comprising a curved surface converging toward a longitudinal axis of said distal tip.

18. The system of claim 1 , further comprising a snare device extending through said second lumen, said snare device having a snare on a distal end thereof.

19. The system of claim 18 , wherein said snare device further comprises a snare on a proximal end thereof.

20. The system of claim 2 , wherein said handle comprises an open proximal end configured to receive an endoscope therethrough.

21. The system of claim 2 , wherein said handle captures said proximal end portion of said elongated body, thereby preventing axial movement of said elongated body with respect to said handle.

22. The system of claim 2 , wherein said handle allows rotation of said elongated body with respect to said handle.

23. The system of claim 2 , wherein said handle prevents rotation of said elongated body with respect to said handle.

24. The system of claim 2 , wherein a recess is provided in a portion of said handle, said recess being configured and dimensioned to receive a light cable that extends from an endoscope, when said endoscope is received in said elongated body.

25. The system of claim 1 , further comprising an insert mounted within said elongated body, wherein said insert and said elongated body cooperate to define said first and second lumens, said first and second lumens each being defined by a surface of said elongated body and a surface of said insert, respectively.

26. The system of claim 25 , wherein said insert forms a friction fit with said elongated body within said elongated body.

27. The system of claim 25 , further comprising a second insert, interchangeable with said first insert, wherein said second insert and said elongated body cooperate to form lumens having at least one of: a different size, different relative positioning and different number of lumens relative to size, positioning and number of said first and second lumens formed in cooperation between said elongated main body and said insert.

28. The system of claim 10 , further comprising a second tip that is interchangeable with said distal tip, said second tip comprising at least one of: a different size, different relative positioning and different number of lumens relative to size, positioning and number of said at least one lumen formed in said distal tip.

29. The system of claim 1 , wherein said distal tip is axially aligned with said first lumen, and wherein said second lumen is not configured for receiving said endoscope therein and is positioned radially outwardly from said first lumen, such that an implement can be delivered though said second lumen and a distal end portion of said implement is deliverable alongside said distal tip.

30. The system of claim 1 , further comprising a suction luer in fluid communication with one of said first and second lumens and extending from said proximal end portion of said elongated body.

31. The system of claim 1 , further comprising an introducer tube in fluid communication with one of said first and second lumens and extending from said proximal end portion of said elongated body.

32. The system of claim 30 , wherein said elongated body comprises three lumens, said system further including an introducer tube in fluid communication with a lumen other than said lumen configured and adapted to receive an endoscope and said lumen in fluid communication with said suction luer, said introducer extending from said proximal end portion of said elongated body.

33. The system of claim 1 , wherein said distal tip is releasably attachable to said elongated body.

34. The system of claim 1 , further comprising a suction tube extending through one of said first and second lumens and providing fluid communication between said distal and proximal end por
