    摘要: A surgical instrument for cutting tissue, which includes a housing, a cutting element movable between a retracted position disposed substantially within the housing and a deployed position extending outwardly from the housing, a guide member configured and dimensioned to direct orientation of the cutting element, operatively connected to the housing and defining a longitudinal axis, the guide member movable from a first orientation wherein the longitudinal axis of the guide member is aligned with a longitudinal axis of the housing to a second orientation wherein the longitudinal axis of the guide member is oriented at a predetermined angle relative to the longitudinal axis of the housing. A method for surgically removing tissue is also provided and includes the steps of inserting an instrument into an incision formed at the operative site, deploying a blade guide at an angle relative to a longitudinal axis of the instrument, deploying a cutting element from a retracted position to an exposed position such that the cutting element is guided by the blade guide, moving the cutting element through a predetermined path such that a section of tissue is separated from the surrounding tissue, and removing the cut tissue from the surrounding tissue.

    摘要: A valve assembly is provided for permitting the introduction of a surgical instrument into a patient's body while providing a substantial seal about the instrument. The valve assembly includes a sealing gasket assembly providing a fluid tight seal before instrument insertion, and is configured and dimensioned for accommodating an instrument and providing a substantial fluid tight seal after insertion of an instrument. The valve assembly may further include a deformable sealing member having a substantially central aperture for accommodating the instrument. The sealing member provides a substantial seal about the instrument when the instrument is passed therethrough impeding the egress of fluids and gasses through the valve assembly.
