Abstract
A device and method useful for guiding insertion of a surgical device with image guided surgery. The device includes a base that may be connected to a fixation device to hold the device in place, and a guide for the surgical device. The guide is connected to the base by a semispherical ball joint, which allows the trajectory of the guide to be adjusted. The device includes an adjustable depth stop that controls the distance the surgical device is inserted into the patient. A positional indicator is attached to the depth stop. An insertion indicator signals when the depth stop is set so as to limit the insertion distance to that necessary to treat the target tissue within the patient.

24. A device for controlling the insertion of a surgical device into the body of a patient comprising:
-
a guide for the surgical device;
a positional indicator;
an adjustable stop for limiting the distance the surgical device can be inserted into the body;
a first fixture for the positional indicator associated with the guide; and
a second fixture for the positional indicator operatively associated with the stop, wherein by determining the position of the positional indicator in the first and second fixtures, the stop can-be set so that the surgical instrument can be inserted a limited distance into the body. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A method for guiding a surgical device, the method comprising the steps of:
-
positioning a surgical device guide in relation to a patient using an image guided surgery system, the surgical device comprising;
a base having an aperture therein, the aperture having an annular surface;
a guide for the surgical device having an aperture engaging end, the aperture engaging end being outwardly flared; and
a curved outer surface at the aperture engaging end that is compatible with the annular surface of the aperture;
a positional indicator;
a positional lock for fixing the position of the device with respect to the body; and
a trajectory lock for fixing the trajectory of the device with respect to the body;
using the image guided surgery system to determine the trajectory of the surgical device guide;
locking the trajectory of the guide; and
inserting a surgical device into the guide.

32. A device for controlling the insertion of a surgical device into the body of a patient comprising:
-
an adjustable stop for limiting the distance the surgical device can be inserted into the body;
a positional indicator;
a first fixture for the positional indicator associated with the surgical device; and
a second fixture for the positional indicator operatively associated with the stop, wherein by determining the position of the positional indicator in the first and second fixtures, the stop can be set so that the surgical instrument can be inserted a limited distance into the body. - View Dependent Claims (33, 34, 35, 36, 37, 38)

39. A method for treating tissue in a body volume with a surgical device, the method comprising the steps of:
-
collecting image data associated with the body volume using an imaging device;
creating an image from the image data;
displaying the image on a display screen;
selecting at least one tissue target in the body volume for treatment;
determining an insertion distance for the surgical device, such that the surgical device may be used to treat the tissue target when inserted the insertion distance into the body volume;
providing an adjustable stop for limiting the distance the surgical device may be inserted in the body volume;
placing a positional indicator at a first fixture associated with the surgical device;
placing the positional indicator at a second fixture associated with the adjustable stop;
determining the position of the positional indicator in the first and second fixtures, such that the adjustable stop can be set so that the surgical device can be inserted the insertion distance;
setting the adjustable stop to limit insertion of the surgical device to the insertion distance;
inserting the surgical device the insertion distance; and
treating the tissue target.
