Claims9
A surgical device comprising:
- an inner tube having a first open end and a second open end, the inner tube having a first diameter;
- an outer tube having a second diameter, the second diameter being greater than the first diameter, at least a portion of the outer tube being configured to encompass the inner tube;
- a cutting edge positioned proximate to the first open end of the inner tube;
- the cutting edge being configured to rotate;
- a denticulate shield configured to project distally from a first end of the outer tube and extend around a portion of a circumference of the outer tube, the denticulate shield including at least one notch, wherein the at least one notch is positioned on a first sidewall of the denticulate shield, wherein the outer tube and the denticulate shield are configured to move along a longitudinal axis while the inner tube remains stationary.
