Abstract

A femoral drill guide assembly constructed in accordance to one example of the present disclosure includes a handle portion, a parallel slider, a perpendicular slider, a feeder guide and a receiving guide. The handle portion can extend along a first plane and include a first adjustable mating portion formed thereon. The parallel slider can have a second and a third adjustable mating portion thereon. The first and second adjustable mating portions can selectively move relative to each other causing the parallel slider to move relative to the handle portion between a plurality of positions along the first plane. The perpendicular slider can extend along a second plane and have a fourth adjustable mating portion thereon. The third and fourth adjustable mating portions can selectively move relative to each other causing the perpendicular slider to move relative to the parallel slider between a plurality of positions along the second plane.

First claim

What is claimed is:

1. A femoral drill guide assembly comprising:
a handle portion that extends along a first plane between a first handle end and an opposite second handle end, the first handle end including a first adjustable mating portion formed thereon;
a parallel slider that extends between a parallel slider first end and an opposite parallel slider second end, the parallel slider having a second and a third adjustable mating portion thereon, wherein the first and second adjustable mating portions selectively move relative to each other causing the parallel slider to move relative to the handle portion between a plurality of positions along the first plane;
a perpendicular slider that extends along a second plane between a perpendicular slider first end and an opposite perpendicular slider second end, the perpendicular slider having a fourth adjustable mating portion thereon, wherein the parallel and perpendicular sliders are coupled by way of the third and fourth adjustable mating portions, and the third and fourth adjustable mating portions are configured to selectively move relative to each other along the second plane but not the first plane, thereby causing the perpendicular slider to move relative to the parallel slider between a plurality of positions along the second plane but not the first plane;
a feeder guide movably coupled to the perpendicular slider, the feeder guide including a cannulation configured to direct a guide wire along a first longitudinal axis; and
a receiving guide coupled to the handle portion, the receiving guide having a receiving end including an aperture configured to accept the guide wire from the feeder guide, wherein the first longitudinal axis intersects with the aperture.

2. The femoral drill guide assembly of claim 1 wherein the receiving end of the receiving guide includes a funnel-shaped surface formed about the aperture, the funnel-shaped surface configured to guide the guidewire through the aperture.

3. The femoral drill guide assembly of claim 2 wherein the receiving guide comprises a first guide body portion that extends along a first axis and a second guide body portion that extends along a second axis, wherein the first and second guide body portions converge at an intermediate non-linear body portion, wherein the first and second axes intersect.

4. The femoral drill guide assembly of claim 3 wherein the receiving guide is cannulated.

5. The femoral drill guide assembly of claim 3 wherein the receiving guide is rotatably fixed to the second handle end, whereby the receiving guide is configured to selectively rotate along the second axis.

6. The femoral drill guide assembly of claim 3 wherein the second guide body portion of the receiving guide is configured to adjustably translate along the second axis relative to the handle portion to locate the receiving end, including the aperture, at a plurality of positions.

7. The femoral drill guide assembly of claim 1 wherein one of the first and second adjustable mating portions comprises a first slot and the other of the first and second adjustable mating portions comprises a first locating member, wherein the first locating member is configured to slidably negotiates along the first slot causing the parallel slider to move relative to the handle portion between the plurality of positions along the first plane.

8. The femoral drill guide assembly of claim 7 wherein the first locating member collectively comprises a first screw that threadably mates with a receiving disk, the first screw movable between (i) a locked position with the disk wherein the first locating member is fixed to the handle portion and (ii) an unlocked position with the disk wherein the first locating member moves along the first slot and the parallel slider moves relative to the handle portion.

9. The femoral drill guide assembly of claim 8 wherein the first slot is arcuately shaped along the handle portion.

10. The femoral drill guide assembly of claim 1 wherein one of the third and fourth adjustable mating portions comprises a second slot and the other of the third and fourth adjustable mating portions comprises a second locating member, wherein the second locating member is configured to slidably negotiates along the second slot causing the perpendicular slider to move relative to the parallel slider between the plurality of positions along the second plane but not the first plane.

11. The femoral drill guide assembly of claim 10 wherein the second locating member collectively comprises a second screw that threadably mates with a receiving member, the second screw movable between (i) a locked position with the receiving member wherein the second locating member is fixed to the perpendicular slider and (ii) an unlocked position with the receiving member wherein the second locating member moves along the second slot and the perpendicular slider moves relative to the parallel slider.

12. The femoral drill guide assembly of claim 11 wherein the second slot is arcuately shaped along the perpendicular slider.

13. The femoral drill guide assembly of claim 1 wherein the parallel slider is arcuately shaped.

14. The femoral drill guide assembly of claim 1 wherein the perpendicular slider is arcuately shaped.

15. A femoral drill guide assembly comprising:
a handle portion that extends along a first plane and including a first adjustable mating portion formed thereon;
a first adjustable member having a second and a third adjustable mating portion formed thereon, wherein the first and second adjustable mating portions are configured to selectively move relative to each other causing the first adjustable member to move relative to the handle portion between a plurality of positions along the first plane;
a second adjustable member that extends along a second plane, the second adjustable member having a fourth adjustable mating portion thereon, wherein the first and second adjustable members are coupled by way of the third and fourth adjustable mating portions, and the third and fourth adjustable mating portions are configured to selectively move relative to each other causing the second adjustable member to move relative to the first adjustable member between a plurality of positions along the second plane but not the first plane, the first and second planes being distinct;
a feeder guide movably coupled to the second adjustable member, the feeder guide including a cannulation configured to direct a guide wire along a first longitudinal axis; and
a receiving guide coupled to the handle portion, the receiving guide having a funnel-shaped receiving end including an aperture configured to accept the guide wire from the feeder guide, wherein the first longitudinal axis intersects with the aperture.

16. The femoral drill guide assembly of claim 15 wherein the receiving guide comprises a first guide body portion that extends along a first axis and a second guide body portion that extends along a second axis, wherein the first and second guide body portions converge at an intermediate non-linear body portion, wherein the first and second axes intersect.

17. The femoral drill guide assembly of claim 15 wherein one of the first and second adjustable mating portions comprises a first slot and the other of the first and second adjustable mating portions comprises a first locating member, wherein the first locating member is configured to slidably negotiates along the first slot causing the first adjustable member to move relative to the handle portion between the plurality of positions along the first plane.
