Instrument guiding stage apparatus and method for using same
First Claim
1. An apparatus comprising:
- a device for advancing a surgical instrument, the device including;
a base;
a first stage moveably coupled to the base;
a guide tube stop coupled with the first stage, wherein the guide tube stop includes at least one guide tube lumen, an outer ring having a notch, a rocker shaped to fit within the outer ring, the rocker including a stud, a seat received between an inner surface of the ring and the rocker, the seat having legs extending through the outer ring, and a thumbscrew passing through the notch and engaging the stud, the thumbscrew operable to move the rocker; and
a guide tube coupled with the guide tube stop, wherein the guide tube has an outer perimeter dimensioned and configured to snugly couple with a surface defining the guide tube lumen of the guide tube stop, and a guide tube flange adapted to engage with the guide tube stop.

Abstract
This documents describes among other things a normalizing stage apparatus, tools and methods. One example includes a base that defines a trajectory. A first stage is moveably coupled to the base and the first stage moves along the trajectory. A second stage is moveably coupled to the first stage and moves an instrument coupled thereto with respect to the base and the first stage. Before movement of the instrument, the first and second stages are in first positions desired (e.g. predetermined) distances from a target area in the body. Another example includes the first stage and a guide tube stop coupled with the first stage. A guide tube is coupled with the guide tube stop and extends through a guide tube stop lumen. The guide tubes outer perimeter is dimensioned and configured to snugly couple with the surface defining the guide tube stop lumen.

7. An apparatus comprising:
-
a device for guiding a surgical instrument into a body of a patient, the device including; a base including first and second guide rails extending from the base, wherein the base defines a trajectory for guiding the surgical instrument between the first and second guide rails; a first stage moveably coupled to the base, wherein the first stage is moveable alone the trajectory; a second stage moveably coupled to the first stage, wherein the second stage is moveable relative to the first stage on or parallel to the trajectory and operable to move an instrument coupled thereto with respect to the base and the first stage, wherein at least the first stage is positionable at a first position where the first stage is at a desired distance from a target area in the body; a guide tube stop received in a guide tube stop lumen defined in the first stage, wherein the guide tube stop includes at least one guide tube lumen; a guide tube coupled with the guide tube stop, wherein the guide tube has an outer perimeter dimensioned and configured to snugly couple with the surface defining the guide tube stop lumen, and a flange extending at least partially around the outer perimeter of the guide tube, the flange adapted to engage an upper surface of the guide tube stop, wherein the guide tube stop includes an outer ring having a notch, a rocker shaped to fit within the outer ring, the rocker including a stud, a seat received between an inner surface of the ring and the rocker, the seat having legs extending through the outer ring, and a thumbscrew passing through the notch and engaging the stud, the thumbscrew operable to move the rocker to clamp and immobilize the guide tube. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. An apparatus comprising:
-
a device for advancing a surgical instrument into a body of a patient, the device including; a base including first and second guide rails extending from the base, wherein the base defines a trajectory for guiding an instrument between the first and second guide rails; a first stage moveably coupled to the base, wherein the first stage is moveable along the trajectory, the first stage including an upper portion defining first and second guide rail lumens slidably coupled with the first and second guide rails, and a lower portion defining two guide rail lumens slidably coupled with the first and second guide rails; a first stage actuator having an inner surface threadably engaged with a stationary screw, the stationary screw substantially perpendicularly coupled to the base, the first stage actuator coupled to the lower portion of the first stage and rotatable to move the first stage along the trajectory and along the stationary screw; a thumbscrew passing through the first stage and engageable with one of the first or second guide rails for immobilizing the first stage relative to the base; a second stage moveably coupled to the first stage, wherein the second stage is moveable relative to the first stage on or parallel to the trajectory and operable to move an instrument coupled thereto with respect to the base and the first stage; a rotatable threaded screw rotatably coupled to the first and second stages, the rotatable screw passing through the upper and lower portions of the first stage, the rotatable screw offset relative to the stationary screw; and a second stage actuator cooperatively engaging the rotatable screw for advancing the second stage relative to the first stage; wherein at least the first stage is in a first position where the first stage is a desired distance from a target area in the body. - View Dependent Claims (28, 29, 30, 31, 32)
