Summary:An instrument for treating a sinus cavity includes a cutter member, a rotatable member, and a fluid passage. The cutter member has a lumen extending therealong, and the rotatable member is received within the lumen. The rotatable member has a helical blade projecting from a distal end portion. The cutter member is configured to translate relative to the rotatable member. Thereby, the cutter memberand the rotatable blade are configured to form an opening into the sinus cavity. The fluid passage extends through the cutter member from an inlet to an outlet. The outlet is positioned proximal to the helical blade such that the outlet is configured to fluidly communicate with the sinus cavity. The inlet is configured to receive at least one of a fluid and a vacuum in order to communicate the respective fluid or vacuum to the outlet for irrigating or suctioning the sinus cavity. 本发明公开了种用于治疗窦腔的器械，该器械包括切割器构件、可旋转构件、以及流体通道。所述切割器构件具有沿其延伸的管腔，并且所述可旋转构件接纳在所述管腔内。所述可旋转构件具有从远侧端部部分突出的螺旋刀片。所述切割器构件被构造成相对于所述可旋转构件平移。由此，所述切割器构件和所述可旋
