Abstract

A surgical device includes a handle, an elongated tube extending distally from the handle, and a suction tip at a distal end portion of the elongated tube. The suction tip has a cavity formed therein. A cutting blade is positioned at least partially within the cavity and rotatable across the cavity to sever tissue, the cavity dimensioned to receive the severed tissue for removal from a patient's body.

Claims (27)

1. A surgical device, comprising:

a handle;

an elongate member coupled to the handle and defining a vacuum lumen, the elongate member having a first outer diameter;

a suction tip coupled to the elongate member and defining a cavity in fluid communication with the vacuum lumen of the elongate member, the suction tip having a second outer diameter, the second outer diameter greater than the first outer diameter; and

first and second cutting blades disposed within the suction tip and configured to pivot between an open position and a closed position to sever tissue received within the cavity of the suction tip, the first and second cutting blades cooperatively form a sphere with the suction tip when in the closed position, the first and second cutting blades and the suction tip including exteriorly-exposed outer surfaces that define the sphere.

2. The surgical device according to claim 1 , wherein the first and second cutting blades are disposed within the cavity of the suction tip when in the open position, and the first and second cutting blades protrude distally out of the cavity of the suction tip when in the closed position.

3. The surgical device according to claim 1 , wherein each of the first and second cutting blades is semi-hemispherical in shape.

4. The surgical device according to claim 1 , wherein each of the first and second cutting blades has an outer surface and the suction tip has an inner surface that defines the cavity, the outer surface of each of the first and second cutting blades being in flush engagement with the inner surface of the suction tip when in the open position.

5. The surgical device according to claim 1 , wherein the cavity of the suction tip is outwardly-facing and substantially hemispherical in shape.

6. The surgical device according to claim 1 , wherein the first cutting blade has a first end portion directly, pivotably connected to a first side of the suction tip and a second end portion directly, pivotably connected to a second side of the suction tip.

7. The surgical device according to claim 6 , wherein the second cutting blade has a first end portion pivotably coupled to the first side of the suction tip and a second end portion pivotably coupled to the second side of the suction tip.

8. The surgical device according to claim 7 , wherein the first end portion of each of the first and second cutting blades overlap with one another, and the second end portion of each of the first and second cutting blades overlap with one another.

9. A surgical device system comprising:

a handle;

an elongate member coupled to the handle and defining a vacuum lumen, the elongate member defining a first outer diameter;

a suction tip coupled to the elongate member and defining a cavity in fluid communication with the vacuum lumen of the elongate member, the suction tip defining a second outer diameter, the first outer diameter less than the second outer diameter;

first and second cutting blades disposed within the suction tip and configured to pivot between an open position and a closed position to sever tissue received within the cavity of the suction tip, the first and second cutting blades cooperatively form a sphere with the suction tip when in the closed position, the first and second cutting blades and the suction tip including exteriorly-exposed outer surfaces that define the sphere; and

a container configured to receive the severed tissue from the suction tip.

10. The surgical device system according to claim 9 , wherein the first and second cutting blades are disposed within the cavity of the suction tip when in the open position, and the first and second cutting blades protrude distally out of the cavity of the suction tip when in the closed position.

11. The surgical device system according to claim 9 , wherein each of the first and second cutting blades is semi-hemispherical in shape.

12. The surgical device system according to claim 9 , wherein each of the first and second cutting blades has an outer surface and the suction tip has an inner surface that defines the cavity, the outer surface of each of the first and second cutting blades being in flush engagement with the inner surface of the suction tip when in the open position.

13. The surgical device system according to claim 9 , wherein the cavity of the suction tip is outwardly-facing and substantially hemispherical in shape.

14. The surgical device system according to claim 9 , wherein the first cutting blade has a first end portion directly, pivotably connected to a first side of the suction tip and a second end portion directly, pivotably connected to a second side of the suction tip.

15. The surgical device system according to claim 14 , wherein the second cutting blade has a first end portion pivotably coupled to the first side of the suction tip and a second end portion pivotably coupled to the second side of the suction tip.

16. The surgical device system according to claim 15 , wherein the first end portion of each of the first and second cutting blades overlap with one another, and the second end portion of each of the first and second cutting blades overlap with one another.

17. The surgical device system according to claim 9 , wherein the container includes a bag.

18. The surgical device system according to claim 17 , wherein the bag defines a first aperture and a second aperture spaced longitudinally from the first aperture.
