Patent Images
1. 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.

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.
