Abstract

A surgical device used during a surgical procedure combines a cutting tool and an optical device for removing tissue from a distal area with visual inspection of the tissue that needs to be removed. In a preferred embodiment, the surgical device includes a cutting tool for removing tissue from an internal body part, the cutting tool including a cannula connected to a shaving member that cuts the tissue for removal, and an optical member coupled to the cutting tool for viewing the internal body part during a surgical proceeding.

Claims

1. A surgical device used during a surgical procedure, comprising:

a cutting tool for removing tissue from an internal body part, said cutting tool including a cannula connected to a shaving member that cuts the tissue for removal by the cutting tool; and

an optical member coupled to said cutting tool, said optical member for viewing the internal body part during the surgical procedure.

2. The surgical device of claim 1, wherein said cutting tool includes an aspiration unit for withdrawing the cut tissue from the internal body part, said aspiration unit adapted for coupling to a vacuum source, said aspiration unit including an aspiration channel terminating in a distal aspiration port.

3. The surgical device of claim 1, wherein said optical member includes a telescope.

4. The surgical device of claim 1, further comprising a light source coupled to said optical member for emitting light onto the internal body part.

5. The surgical device of claim 1, wherein the internal body part is in a distal airway region of a patient.

6. The surgical device of claim 5, wherein the internal body part is a trachea.

7. The surgical device of claim 1, wherein said cutting tool is a microdebrider.

8. The surgical device of claim 1, said optical member including a diode and a video connector communicating a video image from said diode to a video unit capable of displaying the image.

9. A surgical device, comprising:

optical means for viewing an internal body part during a surgical proceeding; and

cutting means for removing tissue from an internal body part, said cutting means attached to said optical means for one handed operation.

10. The surgical device of claim 9, wherein said cutting means includes aspiration means for withdrawing the cut tissue from the internal body part, said aspiration means adapted for coupling to a vacuum source, said aspiration means including an aspiration channel terminating in a distal aspiration port.

11. The surgical device of claim 9, wherein said optical means includes is a telescope.

12. The surgical device of claim 9, further comprising a light source coupled to said optical means for emitting light onto the internal body part.

13. The surgical device of claim 9, wherein the internal body part is in a distal airway region of a patient.

14. The surgical device of claim 9, wherein said cutting means includes a microdebrider.

15. The surgical device of claim 9, said optical means including a diode and a video connector communicating a video image from said diode to a video unit capable of displaying the image.

16. A method for removing tissue from a distal airway of a patient, comprising inserting a surgical device having a shaving member and an optical member coupled to the shaving member through a patients mouth into the distal airway, viewing the tissue via the optical member, shaving the tissue from the distal airway with the shaving member, and withdrawing the shaved tissue from the distal airway.
