1. A surgical instrument comprising:
- a handle assembly; and
a distal assembly connected to said handle assembly, said distal assembly comprising;
a blade having a first width;
a lower blade structure having an upper face which has a second width extending between a first lateral side and a second lateral side, said blade being slidably coupled to said lower blade structure, wherein said first width is equal to or less than said second width.

Abstract
A reciprocating surgical file system for precisely removing bone and/or other tissue is described. The system allows a user to maneuver the system and navigate into hard-to-access sites under a direct vision mechanism. A transmission mechanism converts rotary motion from a motor into reciprocating motion and provides it to the surgical file for precision removal of bone or other tissue. A pulsatile pump mechanism is operatively coupled with the transmission mechanism and provides irrigating fluid to the surgical site.
