Active Instrument Port System for Minimally-Invasive Surgical Procedures

摘要

An access system for surgical procedures includes an insertion tube having a distal end and a lumen, a pair of instrument delivery tubes extending through the lumen of the insertion tube, each instrument delivery tube having a fixed longitudinal position relative to the insertion tube and a steerable distal portion positioned distal to the distal end of the insertion tube. Proximal actuators are moveable to steer the distal portions of the instrument delivery tubes through manipulation of the handles of instruments extending through those tubes. First and second rigid tubes are mounted within the lumen, at least one of which has a distal end disposed within the lumen.
