  • Rotatable surgical cutting instrument with positionally adjustable window
    Patent number: 5376078
    Abstract: Angular positional adjustment relative to a handpiece is provided for a cutting window located at the distal end of an outer tube in an endoscopic surgical cutting instrument. A two-member hub assembly for the outer tube includes one hub member having a polygonal socket and a second hub member having a polygonal plug. Axial disengagement of the plug and socket permits relative rotation between them to provide alternative engagement positions. One hub member engages the handpiece while the other has the outer tube secured thereto, whereby changes in the angular engagement position between the hub members results in changes of the angular position of the cutting window relative to the handpiece.
