Abstract:
1. A system comprising: a cannula extending along a longitudinal axis and comprising a lumen; a surgical instrument coaxial with the cannula, the surgical instrument being sized to perform a surgical procedure through the lumen; a positioning mechanism directly coupled to the cannula and the surgical instrument for moving the surgical instrument relative to the cannula, the positioning mechanism comprising a fixed element directly coupled to the cannula and an articulating element directly coupled to the surgical instrument such that the surgical instrument extends perpendicular to the articulating element, the fixed element comprising a first arm extending transverse to the axis and a second arm coupled to the first arm extending parallel to the axis, the articulating element being configured for axial translation along the second arm; and a remote position controller for providing a control signal to the positioning mechanism, the positioning mechanism moving the surgical instrument relative to the cannula in response to the control signal.
