OCT PROBE WITH PIVOTING FIBER

摘要

An OCT probe for imaging patient tissue may include an actuation system arranged to displace an optical fiber within a cannula. The actuation system may include a driver actuatable to displace a portion of the optical fiber, with the driver acting in an angled direction relative to the axis of the cannula. The actuation system also may include a pivot feature operably engaged with the optical fiber in a manner permitting the optical fiber to pivot on the pivot feature when the driver actuates to displace the portion of the optical fiber.

1. An OCT probe for imaging patient tissue, comprising:
a cannula having a cannula axis; a selectively displaceable light-carrying optical fiber disposed within the cannula and having a distal end, the optical fiber being adapted to emit light from the distal end and; an actuation system arranged to displace the optical fiber within the cannula, the actuation system comprising:
a driver actuatable to displace a portion of the optical fiber, the driver acting in an angled direction relative to the cannula axis; anda pivot feature operably engaged with the optical fiber, the optical fiber pivotable about the pivot feature in response to a displacement of the portion of the optical fiber by the driver; and a stiffening tube disposed about the optical fiber and separating the optical fiber and the pivot feature, the stiffening tube directly engaging the pivot feature in a pivot relationship.
