ABSTRACT:
A surgical suction cutting instrument includes a tubular outer member defining a cutting chamber with an opening, an inner member with a distal cutting edge movably received in the outer tubular member and a flushing mechanism for supplying fluid to the cutting chamber via an outlet communicating with the cutting chamber. The cutting edge of the inner member is disposed within the cutting chamber adjacent the opening to engage bodily tissue through the opening, and a lumen is preferably defined through the inner tubular member in communication with the cutting chamber for aspirating cut bodily tissue. In one embodiment, the flushing mechanism includes a tubular member disposed alongside the outer tubular member and having an outlet communicating with the cutting chamber for supplying fluid to the cutting chamber to prevent and clear clogging of the passage without the need of having to remove the cutting instrument from the surgical site.
