ABSTRACT:
A rotatable shaver in the form of an endoscopic burr instrument suitable for use at a non-fluid filled surgical site. The burr instrument comprises an elongated tubular outer member and an elongated tubular inner member rotatably situated within the outer member. A burr or other abrading tool is secured to the distal end of the inner member and abraded tissue and other debris is or may be aspirated through the lumen of the inner member. A fluid inlet port in the outer member provides irrigating fluid to the proximal end of the outer member and the fluid is conveyed to one or more longitudinally extending fluid channels between the inner and outer members. The channel or channels direct the fluid distally from an outlet port at the distal tip of the outer member in order to irrigate the surgical site. In order to prevent irrigating fluid from being directly aspirated, a barrier is provided to separate the burr tip and the outlet port from the entrance to the lumen of the inner member.
