A surgical introducer including a body portion, a shaft and a sensor is disclosed. The body portion includes a reference indicator. The shaft defines a longitudinal axis and is positionable adjacent the body portion. The shaft is rotatable with respect to the body portion and includes a longitudinal indicator and a circumferential indicator. The sensor is disposed in mechanical cooperation with a distal portion of the shaft and is adapted to provide physiological data pertaining to a surgical worksite. At least a portion of the sensor is substantially aligned with the circumferential indicator. Rotation of the shaft with respect to the body portion causes displacement between the circumferential indicator and the reference indicator. Longitudinal movement of the shaft with respect to the body portion causes displacement between the longitudinal indicator and the reference indicator.
