Abstract

The instant invention describes a surgical tool for providing cavitations, or void spots, within the interior of body regions. The surgical tool is constructed and arranged to penetrate almost all interior body regions in which formation of a cavity or void space is necessary for diagnostic or treatment purposes. The surgical tool comprises an insertable member receiving structure sized and shaped to receive one or more insertable devices. The interior lumen of the insertable member receiving structure allows the insertable device to slide and/or rotate relative to the insertable member receiving structure and vice versa. At least one insertable member is a cavity forming device which has a plurality of cavity forming members constructed and arranged with spring-like characteristics for traversing between a cavity forming position and a non-cavity forming position. Upon traversal back to the cavity forming position, the displacement members retain their cavity forming structural configurations.

Claims

1. A device for creating cavities or void spaces within a tissue or organ comprising:

an insertable member receiving structure containing a proximal end, a distal end, and a main body therebetween, said insertable member receiving structure main body containing a longitudinal bore sized and shaped to receive an insertable member;

a first insertable member rotatably coupleable to said insertable member receiving structure, said first insertable member containing a proximal end, a distal end, and a first insertable member main body therebetween, said distal end having a tip with one or more displacement members adapted for traversing between a cavity forming position and a non-cavity forming position;

whereby rotation of said first insertable member displaces cells, cellular debris, or tissue components from a body organ or tissue thereby forming a void or cavity region therein.

2. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said insertable member receiving structure contains a handle.

3. The device for creating cavities or void spaces within a tissue or organ according to claim 2 wherein said handle is ergonomically shaped.

4. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said insertable member receiving structure contains a tissue or organ engaging tip.

5. The device for creating cavities or void spaces within a tissue or organ according to claim 4 wherein said tissue or organ engaging tip is a multi-faceted, triple crown cannulated tip.

6. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said insertable member receiving structure main body contains one or more stabilizing members.

7. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said first insertable member further contains a device for gripping and aiding in rotating said first insertable member.

8. The device for creating cavities or void spaces within a tissue or organ according to claim 7 wherein said device is a knob.

9. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said displacement members are made of superelastic alloys which can be constrained into a first shape and then deployed to a second shape without experiencing plastic deformity.

10. The device for creating cavities or void spaces within a tissue or organ according to claim 9 wherein said material is nitinol.

11. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said displacement members contain curved portions with generally rounded terminal ends.

12. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said displacement members contain hooked or semi-hooked terminal ends.

13. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said displacement members are coupled to a center member.

14. The device for creating cavities or void spaces within a tissue or organ according to claim 13 wherein said displacement members are coupled to said center member to form a generally S-shaped configuration.

15. The device for creating cavities or void spaces within a tissue or organ according to claim 13 wherein said displacement members have at least one edge angled to form a V-shape body.

16. The device for creating cavities or void spaces within a tissue or organ according to claim 15 wherein said displacement members have at least one edge angled to form a V-shape body and a generally S-shaped terminal portion.

17. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said first insertable tip member contains a single displacement member.

18. The device for creating cavities or void spaces within a tissue or organ according to claim 13 wherein said displacement members are arranged to expand into a cavity forming position independently whereby said first or second displacement members expand prior to said second or first displacement member.

19. The device for creating cavities or void spaces within a tissue or organ according to claim 13 wherein said displacement members are arranged to expand into a cavity forming position simultaneously.

20. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said center member contains a tip member at the distal end.

21. The device for creating cavities or void spaces within a tissue or organ according to claim 20 wherein said tip member is movably coupled to said center member, said tip movable towards the proximal end when encountering a predetermined force.

22. The device for creating cavities or void spaces within a tissue or organ according to claim 21 wherein said displacement members are released to a cavity forming position when said tip member moves toward said proximal end.

23. The device for creating cavities or void spaces within a tissue or organ according to claim 1 wherein said tip member contains 3 or more displacement members.

24. The device for creating cavities or void spaces within a tissue or organ according to claim 23 wherein each of said displacement members is the same or similarly sized, whereby in the closed position, all said displacement members align forming an edge that is generally linear

25. The device for creating cavities or void spaces within a tissue or organ according to claim 23 wherein at least one displacement member includes a pointed member at the distal end.

26. The device for creating cavities or void spaces within a tissue or organ according to claim 25 wherein the lengths of at least one of said displacement members is smaller than the length of at least one second displacement member.

27. A system for creating cavities or void spaces within a tissue or organ comprising:

an insertable member receiving structure containing a proximal end, a distal end, and a main body therebetween, said insertable member receiving structure main body containing a longitudinal bore sized and shaped to receive an insertable member;

at least one first insertable member rotatably coupleable to said insertable member receiving structure, said first insertable member containing a proximal end, a distal end, and a first insertable member main body therebetween, said distal end having a tip with one or more displacement members adapted for traversing between a cavity forming position and a non-cavity forming position;

whereby rotation of said first insertable member displaces cells, cellular debris, or tissue components from a body organ or tissue to form a void or cavity therein.

28. The system for creating cavities or void spaces within a tissue or organ according to claim 27 further including a second insertable member having a proximal end having a gripping member, a distal end containing a pointed end for inserting into a hard surface, and a second insertable member main body traversing between said distal end and said proximal end, said second insertable member being sized and shaped to be insertable and traversable within said lumen of said insertable member receiving structure.

29. A kit for creating cavities or void spaces within a tissue or organ comprising:

an insertable member receiving structure containing a proximal end, a distal end, and a main body therebetween, said insertable member receiving structure main body containing a longitudinal bore sized and shaped to receive an insertable member;
