Abstract
An articulated endoscope for performing endoscopic procedures in a tubular organ of a patient is provided, comprising a chassis, a plurality of pressure driven linear actuators mounted, by proximal ends, in oppositely facing pairs to the chassis, control means mounted to the chassis for storing a predetermined pressure distribution sequence therein and for outputting the predetermined sequence in response to a directional input from a user, means for receiving and distributing pressure to the plurality of pressure driven linear actuators in the predetermined pressure distribution sequence in response to control signals from the control means, the means for receiving and distributing being mounted to the chassis, and a tube delivering pressure to the means for receiving and distributing pressure, whereby self-propelled motive force is produced by pushing against interior surfaces of the tubular organ with distal ends of the plurality of pressure driven linear actuators as pressure is applied to the plurality of pressure driven linear actuators in the predetermined pressure distribution sequence.
