摘要： A surgical cutting instrument is disclosed in FIG.4 for percutaneously debulking tissue through an access sheath. The cutting instrument includes an inner rotary member tube 401 having a cutting edge 407 at the distal end thereof for cutting and slicing tissue. The outside surface of the rotary inner cutting member tube and outer sheath 409 annularly close about the distal ends thereof for preventing perforation of the surgical tissue bag in which the tissue is contained. The inner cutting member tube includes a hollow passageway for suctioning and aspirating tissue and fluid through the tube and into a collection chamber 419 or out through a vacuum or suction line 422 attached thereto. Vacuum or suction control ports are included at the proximal end of the inner cutting member tube and stationary sheath for also controlling the amount of vacuum or suction applied to the tissue. The surgical cutting instrument includes a control handle 431 for grasping by the physician. A collection chamber is connected to a coupler connected to the stationary sheath for collecting tissue therein. The inner cutting member tube extends through the collection chamber to a drive motor 440 or to a remotely positioned rotary drive mechanism. A vacuum line is attached to the collection chamber for drawing tissue and fluid through the inner cutting member tube and into the collection chamber.
