Drill guides for confirming alignment of patient-specific alignment guides
First Claim
1. An orthopedic device comprising:
- a drill guide configured to be mounted on a patient-specific alignment guide for intraoperatively confirming alignment of the patient-specific alignment guide relative to a bone, the patient-specific alignment guide including a first referencing hole and a second referencing hole, the drill guide including;
a main body with a first coupling member and a second coupling member, the first and second coupling members configured to be received within the first and second referencing holes, respectively, the first and second coupling members including corresponding first and second drill openings configured to align with the first and second referencing holes, respectively, for guiding a drilling tool toward the bone to drill corresponding holes in the bone, the main body further including an alignment confirmation feature configured for confirming alignment of the patient-specific alignment guide relative to the bone before drilling holes in the bone,wherein the alignment confirmation feature includes an alignment opening configured to receive a rod, and the alignment opening is configured to allow the rod to at least axially slide and pivot within the alignment opening.

Abstract
An orthopedic device includes a drill guide configured to be mounted on a patient-specific alignment guide for intraoperatively confirming alignment of the patient-specific alignment guide relative to a bone. The patient-specific alignment guide includes first and second referencing holes. The drill guide includes a main body with a first coupling member and a second coupling member. The first and second coupling members are configured to be received within the first and second referencing holes, respectively. The first and second coupling members each include corresponding first and second drill openings configured to align with the first and second referencing holes, respectively. The drill openings each guide a drilling tool toward the bone to drill corresponding holes in the bone. The main body also includes an alignment confirmation feature configured for confirming alignment of the patient-specific alignment guide relative to the bone before drilling holes in the bone.

13. An orthopedic device comprising:
-
a patient-specific alignment guide having a three-dimensional patient-specific surface that nests and closely conforms to a corresponding surface of a bone in only one position relative to the bone, the three-dimensional patient-specific surface being pre-operatively configured to align the alignment guide relative to a mechanical axis of the bone in only one position, the alignment guide including a first referencing hole and a second referencing hole; a drill guide including a main body, a first projection, and a second projection, the first and second projections having first and second through holes, respectively, the first and second projections configured to be received within the first and second referencing holes, respectively, to intra-operatively couple the drill guide to the alignment guide and to guide a drilling tool toward the bone to form corresponding holes therein, the drill guide additionally including an alignment opening configured to orient a rod along an axis parallel to the mechanical axis to confirm the alignment of the patient-specific alignment guide relative to the mechanical axis of the bone, wherein the alignment opening is configured to allow the rod to at least axially slide and pivot within the alignment opening.

19. An orthopedic device comprising:
-
a patient-specific alignment guide having a three-dimensional patient-specific surface that nests and closely conforms to a corresponding surface of a bone in only one position relative to the bone, the three-dimensional patient-specific surface being pre-operatively configured to align the alignment guide relative to a mechanical axis of the bone in only one position, the alignment guide including a first referencing hole and a second referencing hole; a drill guide including a main body, a first projection, and a second projection, the first and second projections configured to be received within the first and second referencing holes, respectively, to intra-operatively couple the drill guide to the alignment guide and to guide a drilling tool toward the bone to form a corresponding hole therein, the drill guide additionally including at least one drill opening and an alignment opening configured to orient a rod along an axis parallel to the mechanical axis to confirm the alignment of the patient-specific alignment guide relative to the mechanical axis of the bone, wherein the alignment opening is configured to allow the rod to at least axially slide and pivot within the alignment opening. - View Dependent Claims (20, 21, 22)
