Abstract: A cannula is provided that includes a head portion that defines a proximal opening sized to receive one or more surgical instruments; an elongated inner tube rigidly fastened to the head portion defines an elongated conduit; a surgical instrument can be inserted within the conduit; an elongated overtube rigidly fastened to the head portion is coaxially aligned with the inner tube and extends about a portion of the inner tube; an inner wall of the overtube is spaced apart from an outer wall of the inner tube; sensors are disposed on the overtube to provide an indication of forces applied to the outer wall of the overtube in a direction generally transverse to the longitudinal dimension of the overtube.
