Abstract
An instrument system that includes an image capture device, an elongate body, an optical fiber and a controller is provided. The elongate body is operatively coupled to the image capture device. The optical fiber is operatively coupled to the elongate body and has a strain sensor provided on the optical fiber. The controller is operatively coupled to the optical fiber and adapted to receive a signal from the strain sensor and to determine a position or orientation of the image capture device based on the signal.
Claims8
An instrument system, comprising:
- an image capture device extending through a sheath member and configured to image at least a portion of an anatomical workspace of a patient;
- an elongate body operable only manually and operatively coupled to the image capture device;
- an optical fiber operatively coupled to the elongate body, the optical fiber comprising a strain sensor provided thereon;
- and
- a controller operatively coupled to the optical fiber and adapted to:
- receive a signal from the strain sensor;
- and
- determine a position and/or an orientation of the image capture device based on the signal from the strain sensor provided on the optical fiber,
- wherein the optical fiber is further positioned on the image capture device.
