<p>A surgical instrument is steerable from the hub of the instrument to move a surgical tool to different offset positions. The instrument includes a shaft disposed along a longitudinal axis between a proximal region and a distal region at which the surgical tool is supported. A steering body is connected to the shaft proximally of the surgical tool and is configured to transmit proximally directed and distally directed forces applied by an actuator to a proximal end thereof to the shaft to bend the shaft in a flexible region of the shaft and offset the surgical tool from the longitudinal axis of the shaft.</p> |
