Surgical Introducer with Indicators
First Claim
1. A surgical introducer, comprising:
- a body portion including a reference indicator;
a shaft defining a longitudinal axis and positionable adjacent the body portion and rotatable with respect to the body portion, the shaft including a longitudinal indicator and a circumferential indicator; and
a sensor disposed in mechanical cooperation with a distal portion of the shaft and adapted to provide physiological data pertaining to a surgical worksite, at least a portion of the sensor substantially aligned with the circumferential indicator,wherein rotation of the shaft with respect to the body portion causes displacement between the circumferential indicator and the reference indicator and allows a user to determine the circumferential movement of the sensor, and wherein longitudinal movement of the shaft with respect to the body portion causes displacement between the longitudinal indicator and the reference indicator and allows a user to determine the longitudinal movement of the sensor.

Abstract
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.

8. A method of ascertaining physiological data, comprising the steps of:
-
providing a surgical introducer, the surgical introducer including a body portion, a shaft, and a sensor; positioning the surgical introducer within tissue; measuring a physiological attribute of the tissue with the sensor when the surgical introducer is in an initial position; moving the shaft with respect to the body portion such that the surgical introducer is in a second position; and measuring a physiological attribute of the tissue with the sensor when the surgical introducer is the second position. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A method of ascertaining physiological data, comprising the steps of:
-
providing a surgical introducer, the surgical introducer including; a body portion including a reference indicator; a shaft defining a longitudinal axis and being positionable adjacent the body portion and being rotatable with respect to the body portion, the shaft including a longitudinal indicator and a circumferential indicator; and a sensor disposed in mechanical cooperation with the shaft, at least a portion of the sensor being substantially aligned with the circumferential indicator; positioning the surgical introducer within tissue; taking a first measurement with the sensor when the surgical introducer is in an initial position; moving the shaft with respect to the body portion such that the surgical introducer is in a second position; and measuring a physiological attribute of tissue when the surgical introducer is the second position.
