Abstract
A surgical instrument includes a cutting member with an implement for cutting tissue, and a drive coupled to the cutting member. The drive may include a drive member having a helical groove and being attached to the cutting member. Furthermore, the drive may include an inner drive hub coupled to the drive member such that the drive member rotates with the inner drive hub while being free to translate relative to the inner drive hub. The drive simultaneously rotates and translates the cutting member in response to a force applied to the drive.
