Abstract:
A system for graphically visualizing an orientation of a steerable distal portion of an elongate instrument is disclosed. The system includes an instrument having an elongate body. The elongate body includes a proximal portion and a steerable distal portion. The system also includes at least one tensioning member attached to said steerable distal portion, wherein the actuation of said at least one tensioning member results in an approximate y-bend and an approximate x-bend of said steerable distal portion, and wherein said approximate y-bend and approximate x-bend define an approximate overall bend of said steerable distal portion. The system further includes a graphical user interface and an icon representing said approximate overall bend on said graphical user interface.
Abstract:
A steerable device may comprise an elongate, flexible body comprising a plurality of articulatable segments along at least part of a length of the body, a plurality of coil pipes extending in a spiral configuration along the articulatable segments, a plurality of tendons respectively received within the plurality of coil pipes, and an actuator coupled to the plurality of tendons, the actuator being configured to apply an actuation force to the tendons to selectively actuate articulation of the articulatable segments.
