1. A surgical instrument comprising:
- a blade for removing tissue, said blade having a plurality of throughholes; and
a lower blade structure that couples to said blade;
wherein said lower blade structure comprises a fluid delivery channel that extends substantially along a long axis of said lower blade structure;
wherein at least a portion of said fluid delivery channel is aligned with at least one of said throughholes in said blade so as to permit flow through said at least one of said throughholes; and
wherein said blade is configured to move along said long axis with respect to said lower blade structure.

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.

10. A surgical instrument comprising:
-
means for removing tissue from a mammal; and
means for delivering fluid through said means of removing tissue;
wherein movement of said means for removing tissue relative to said means for delivering fluid produces substantially pulsatile flow.

11. The surgical instrument, comprising:
-
a blade configured to remove tissue from a patient; and
a lower blade structure that couples with said blade;
wherein reciprocating motion of said blade with respect to said lower blade structure generates substantially pulsatile flow of fluid through said blade when said fluid is supplied to said lower blade structure at a substantially constant pressure. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
