Abstract

A sinus debrider apparatus comprising a housing, a motor mounted in the housing and a cutter head is mounted to the housing. The cutter head frustum conical shaped and defines an interior chamber, a suction passageway and a fluid passageway. A blade holder is mounted to the head and axially aligned with the interior chamber with a blade member being rotatably mounted in the blade holder. A coupling member is mounted in the interior chamber and connects the motor and the blade member to transmit motion from the motor shaft to the blade member. A manifold member defining separate passageways communicates with the suction passageway and the fluid passageway of the head and forms a connection section to hold a flexible tube providing suction and fluid to the cutter head.
