Abstract

A surgical device and method designed to make insertion of pressure equalization tubes for effusion of the inner ear faster, more reliable, and safer by combining the placement of the pressure equalization tube with suction of the inner ear, decreasing the number of instruments and instrument passes into and out of the ear canal. A surgical insertion tool permits the direct coaxial insertion of the stent through the surgically created ostium, and which may be under direct, clear endoscopic control.

Claims

1. A surgical device in communication with a suction source, said device for suctioning of the middle ear with the insertion and placement of a ventilation tube in the tympanic membrane, said device comprising:

a tubular rod portion having a longitudinal axis, a proximal end, and a distal end with ventilation tube disposed thereon;

an insertion collar portion coaxial to the longitudinal axis of said rod portion to effectively apply a force against the mounted ventilation tube through the tympanic membrane when said rod portion is advanced; and

wherein said rod portion is adapted to allow suction of the middle ear through the distal end of said rod portion during the insertion and/or placement of the ventilation tube.

2. The surgical device, as recited in claim 1, wherein said insertion collar portion is located at a distance from the distal end of said rod portion greater than the axial length of said ventilation tube.

3. The surgical device, as recited in claim 1, wherein said insertion collar portion is located at a distance from the distal end of said rod portion corresponding to the axial length of said ventilation tube.

4. The surgical device, as recited in claim 1, wherein said insertion collar portion is located at a distance from the distal end of said rod portion less than the axial length of said ventilation tube.

5. The surgical device, as recited in claim 1, wherein said collar portion having an extension portion and a non-extension portion, said extension portion having a smaller cross section than non-extension portion thereby defining a shoulder there between;

6. The surgical device, as recited in claim 5, wherein at least a portion of said ventilation tube extends over at least a portion of said extension portion, wherein the applied force is effected by said shoulder contacting said tube.

7. The surgical device, as recited in claim 1, wherein said ventilation tube having a proximal lumen portion and distal lumen portion, said distal lumen portion having a smaller cross section than proximal lumen portion thereby defining a shoulder lumen there between;

8. The surgical device, as recited in claim 7, wherein at least a portion of said ventilation tube extends over at least a portion of said collar portion, wherein the applied force is effected by said shoulder lumen contacting said collar portion.

9. The surgical device, as recited in claim 1, wherein said insertion collar portion is detachable, wherein it can be installed on/or removed from said tubular rod portion.

10. The surgical device, as recited in claim 1, wherein said insertion collar portion and said rod portion are a single integral component.

11. The surgical device, as recited in claim 1, wherein said insertion collar portion and said rod portion are radially axisymmetric.

12. The surgical device, as recited in claim 1, wherein said insertion collar portion is made of a clear material to provide light penetration and/or an unobstructed view of the ear.

13. The surgical device, as recited in claim 1, further comprising a blade.

14. The surgical device, as recited in claim 11, wherein said blade is retractable from said rod portion.

15. The surgical device, as recited in claim 12, wherein said retraction of the blade is controlled by user.

16. The surgical device, as recited in claim 1, wherein said device is made of disposable material.

17. The surgical device, as recited in claim 1, wherein said device is provided in a sterile package or container.

18. The surgical device, as recited in claim 1, wherein said device is pre-loaded with said ventilation tube.

19. The surgical device, as recited in claim 1, wherein said collar portion incorporates one or more protrusions, wherein the applied force is effected by said protrusions contacting said tube.

20. The surgical device, as recited in claim 1, wherein said collar portion extends along said such rod portion, forming an extended sleeve portion.

21. A surgical device in communication with a suction source, said device for suctioning of the middle ear with the insertion and placement of a ventilation tube mounted on a tubular rod portion in the tympanic membrane, wherein said tubular rod portion having a longitudinal axis, a proximal end, and a distal end and is adapted to allow suction of the middle ear through the distal end of said rod portion during the insertion and/or placement of the ventilation tube, said device comprising:

an insertion collar portion coaxial to the longitudinal axis of said rod portion to effectively apply a force against the mounted ventilation tube through the tympanic membrane when said rod portion is advanced.

22. A surgical device for the insertion and placement of a stent in the sinus ostium, said device comprising:

a rod portion having a longitudinal axis, a proximal end, and a distal end with the stent disposed thereon; and

an insertion collar portion coaxial to the longitudinal axis of said rod portion to effectively apply a force against the mounted stent through the sinus ostium when said rod portion is advanced.

23. The surgical device as recited in claim 22, wherein said rod portion is hollow and said surgical device is in communication with a suction source, said device for suctioning of the sinus ostium, and wherein said rod portion is adapted to allow suction of the sinus ostium through the distal end of said rod portion during the insertion and/or placement of the stent.

26. The surgical device as recited in claim 22, further comprising a light source or image or video device or combination thereof in communication with said surgical device.

24. A surgical device for the insertion and placement of a stent in the sinus ostium, wherein said stent is mounted on a rod portion, said device comprising:

an insertion collar portion coaxial to the longitudinal axis of said rod portion to effectively apply a force against the mounted stent through the sinus ostium when said rod portion is advanced.

25. The surgical device as recited in claim 24, where said rod portion is hollow having a longitudinal axis, a proximal end, and a distal end with the stent mounted thereon;

and wherein said surgical device is in communication with a suction source, said device for suctioning of the sinus ostium, and wherein said rod portion is adapted to allow suction of the sinus ostium through the distal end of said rod portion during the insertion and/or placement of the stent.

27. The surgical device as recited in claim 24, further comprising a light source or image or video device or combination thereof in communication with said surgical device.
