  • Orbital dissection cannula and method
    Patent number: 5984937
    Abstract: A cannula and method provide manually manipulable orientation of a dissection probe carried eccentricity on the cannula for rotational and translational positioning relative to the field of view of an endoscope at a distal end of the cannula. Rotation of the cannula at fixed axial position relative to the endoscope, and rotational and translational positioning of the dissection probe relative to the distal end of the cannula provide wide-area access within the surgical site for bluntly dissecting connective tissue surrounding a vessel of interest being harvested.
