Title:
STEERING TECHNIQUES FOR SURGICAL INSTRUMENTS
Document Type and Number:
WIPO Patent Application WO2015077584
Kind Code:
A3
Abstract:
A steerable endoscopic tool uses concentric sleeves of varying curvature to steer a tool tip toward or in the direction of a location of surgical interest. By rotating and/or axially displacing such sleeves relative to one another the tool tip may be maneuvered within a current field of view with several degrees of freedom without any physical movement of an endoscope, thus facilitating improved surgical access and control without complex mechanical systems in the endoscope or at the surgical site.
