METHOD AND APPARATUS FOR INSERTION OF AN ELONGATE PIN INTO A SURFACE
First Claim
1. An apparatus for dictating trajectory and location for insertion of an elongate pin into a surface, the apparatus comprising:
- a trajectory structure configured for contact with the surface to dictate an insertion trajectory of the pin relative to the surface;
a location structure configured to allow longitudinal passage of at least a portion of the pin therethrough to dictate an insertion location of the pin relative to the surface; and
an elongate handling rod connected to the trajectory structure and the location structure and supporting the trajectory structure and the location structure for manipulation by a user;
wherein the handling rod spaces the trajectory structure and the location structure longitudinally apart, the trajectory structure is connected to the handling rod for trajectory adjustment in at least two degrees of freedom relative to the handling rod, and the insertion trajectory of the pin insertion is substantially dependent upon the trajectory adjustment.

Abstract
A trajectory structure is configured for contact with a surface to dictate an insertion trajectory of a pin relative to the surface. A location structure is configured to allow longitudinal passage of at least a portion of the pin therethrough to dictate an insertion location of the pin relative to the surface. An elongate handling rod is connected to the trajectory structure and the location structure. The handling rod supports the trajectory structure and the location structure for manipulation by a user. The handling rod spaces the trajectory structure and the location structure longitudinally apart. The trajectory structure is connected to the handling rod for trajectory adjustment in at least two degrees of freedom relative to the handling rod. The insertion trajectory of the pin insertion is substantially dependent upon the trajectory adjustment. A method for inserting an elongate guide pin into a bone surface is also provided.

10. A guide pin positioning apparatus, comprising:
-
an elongate handling rod having proximal and distal handling rod ends longitudinally spaced apart by a handling rod body, the proximal handling rod end being configured for grasping by a user to manipulate the guide pin positioning apparatus relative to a surface; a trajectory structure connected to the distal handling rod end and configured for selective contact with the surface, the trajectory structure being adjustable in at least two degrees of freedom relative to the handling rod to dictate an insertion trajectory of an elongate guide pin for insertion of the guide pin into the surface; and a location structure connected to the handling rod body at a location longitudinally spaced apart from the trajectory structure, the location structure being configured to allow longitudinal passage of at least a portion of the guide pin therethrough, the location structure dictating an insertion location of the guide pin relative to the surface. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for inserting an elongate guide pin into a bone surface, the method comprising the steps of:
-
providing a trajectory structure adjustable in at least three degrees of freedom relative to the bone surface; providing a location structure connected to and longitudinally spaced from the trajectory structure; dictating an insertion trajectory of the guide pin relative to the bone surface by maintaining the trajectory structure in a predetermined position defined by at least two degrees of freedom relative to the bone surface; contacting the bone surface with the trajectory structure; dictating an insertion location of the guide pin relative to the bone surface by passing at least a distal end of the guide pin longitudinally through the location structure; contacting the bone surface with the distal end of the guide pin at the insertion location; and inserting the distal end of the guide pin into the bone surface along the insertion trajectory. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
