Surgical file system with a visualization instrument
First Claim
Patent Images
1. A surgical instrument comprising:
- a housing that contains a drive system;
a distal assembly having a distal tip configured to grind tissue, file tissue, cut tissue, or combinations thereof, said distal assembly extending from said housing and engaging said drive system of said housing; and
a lumen extending through said housing and said distal assembly, said lumen configured to receive at least a portion of an endoscope such that an optical element of said endoscope is positioned to provide endoscopic viewing of said distal tip.

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.
