Patent Images
1. A measuring guide for assisting in locating a prosthetic device during an orthopedic procedure, comprising:
- a marking guide adapted to facilitate marking of a bone tissue at a desired location;
a stop plate;
a ruler, including a top, a bottom and two sides, the ruler being coupled to the marking guide and to the stop plate, and the ruler indicating the distance between the marking guide and the stop plate, wherein the stop plate includes an abutment surface, configured to abut a bone, and further wherein the abutment surface is positioned on both sides of the ruler; and
a locking mechanism that cooperates with the ruler to permit selective adjustment of the distance between the marking guide and the stop plate by moving the stop plate with respect to the ruler, wherein the marking guide and the stop plate are utilized in a manner noninvasive to the bone tissue, and further wherein the stop plate is pivotably coupled to the locking mechanism to permit positioning of the stop plate at desired angles with respect to the ruler.

Abstract
A measuring guide for use in various surgical procedures. The measuring guide is a noninvasive tool that may be repeatedly applied to a desired bone member to make appropriate measurements. The measuring guide allows for easy adjustment of the distance between a stop plate designed to engage an end of a given bone member and a marking guide used to facilitate marking of the bone. Additionally, the stop plate may be pivotably mounted to facilitate ease and accuracy of measurement.

12. A measuring guide for noninvasive measurement of bone tissue during an orthopedic procedure, comprising:
-
a noninvasive marking guide; a ruler coupled to the marking guide; a noninvasive stop plate coupled to the ruler, the noninvasive stop plate being pivotable, with respect to a pivot point on the ruler, to facilitate transverse placement, with respect to the ruler, against an end surface of a bone; and a locking mechanism that permits selective adjustment of the distance between the noninvasive marking guide and the noninvasive stop plate, wherein the ruler indicates the distance between the noninvasive marking guide and the noninvasive stop plate, wherein the locking mechanism comprises; a block having an opening slidingly receiving the ruler; and a spring-loaded release mechanism biased toward engagement with the ruler to lock the ruler at a desired location with respect to the block. - View Dependent Claims (13, 14, 15)

16. A measuring guide for noninvasive measurement of bone tissue during an orthopedic procedure, comprising:
-
a noninvasive marking guide; a ruler coupled to the marking guide, the ruler defining a longitudinal axis and a transverse axis; a noninvasive stop plate coupled to the ruler, the noninvasive stop plate being pivotable, with respect to the transverse axis of the ruler, to facilitate transverse placement, with respect to the ruler, of an abutment surface of the stop plate against an end surface of a bone, wherein the abutment surface is generally symmetric with respect to both sides of the longitudinal axis defined by the ruler; and a locking mechanism that permits selective adjustment of the distance between the noninvasive marking guide and the noninvasive stop plate, wherein the ruler indicates the distance between the noninvasive marking guide and the noninvasive stop plate. - View Dependent Claims (17, 18, 19, 20)

21. A measuring guide for noninvasive measurement of bone tissue during an orthopedic procedure, comprising:
-
a noninvasive marking guide; a ruler coupled to the marking guide, the ruler defining a longitudinal axis; a noninvasive stop plate coupled to the ruler, the noninvasive stop plate being pivotable, with respect to a pivot point on the ruler, to facilitate transverse placement, with respect to the ruler, of an abutment surface of the stop plate against an end surface of a bone, wherein the abutment surface is generally symmetric with respect to both sides of the longitudinal axis defined by the ruler; and a locking mechanism that permits selective adjustment of the distance between the noninvasive marking guide and the noninvasive stop plate, wherein the ruler indicates the distance between the noninvasive marking guide and the noninvasive stop plate; wherein the noninvasive stop plate is selectively lockable at angles of approximately 84°
, 90° and
96°
relative to the ruler.
