Abstract

An orthopedic device holder and related kit are disclosed. The orthopedic device holder can include a body portion having a proximal end and a distal end, the body portion defining a bore positioned between the proximal end and the distal end, a plunger portion having a proximal end and a distal end, the plunger portion extending into an opening of the body portion and defining a second bore, and a locking lever that, when activated, is configured to move between a first position and a second position and transition the first bore and the second bore from a locked configuration to an unlocked configuration.

First claim

What is claimed is:

1. An orthopedic device holder, comprising:
a body portion having a proximal end and a distal end, the body portion defining a first bore extending in a direction substantially perpendicular to a longitudinal axis of the body portion, the body portion including at least one opening extending into an interior of the first bore;
a plunger portion extending into a channel of the body portion and defining a second bore, wherein the second bore and first bore have identically shaped cross-sectional geometries with respect to one another such that both the second bore and the first bore are configured to interchangeably receive a portion of an orthopedic device, the plunger portion including a slot extending along a portion of the plunger;
a locking bar operably coupled to the body portion and moveable within the slot of the plunger between a first position and a second position, such that in the first position, the locking bar is in a locked configuration with respect to the first bore and in the second position, the locking bar is in an unlocked configuration with respect to the first bore;
a locking sleeve slidably mounted on the plunger portion and moveable between a first position and a second position, such that in the first position, the locking sleeve is in a locked configuration with respect to the second bore, and in the second position, the locking sleeve is in an unlocked configuration with respect to the second bore; and
a locking lever operably coupled to the body portion and configured to move between a first position and a second position to simultaneously transition the locking sleeve and the locking bar from the respective first positions to the respective second positions to connect and release the orthopedic device from either the first bore or the second bore.

2. The orthopedic device holder of claim 1 , wherein the first bore and the second bore have a tri-lobe cross-sectional shape, including three substantially flat surfaces.

3. The orthopedic device holder of claim 2 , wherein for the second bore, the three substantially flat surfaces are positioned equidistant from each other, each of the three substantially flat surfaces configured to engage with three substantially flat surfaces disposed on the orthopedic device.

4. The orthopedic device holder of claim 2 , wherein further comprising at least one opening extending into the interior of the first bore extends through one of the substantially flat surfaces of the first bore.

5. The orthopedic device holder of claim 2 , further comprising at least one opening extending into an interior of the second bore extends through one of the substantially flat surfaces of the second bore.

6. The orthopedic device holder of any one of claim 1 , wherein the first bore is substantially perpendicular to the second bore.

7. The orthopedic device holder of any one of claim 1 , wherein the locking sleeve includes at least one locking ball, the at least one locking ball, when the locking sleeve is in the first position, configured to extend at least partially through the at least one opening in the plunger portion and into a mating recess of an orthopedic device.

8. The orthopedic device holder of claim 7 , wherein the locking sleeve, when in the first position, is configured to provide rotational constraint and axial constraint of the orthopedic device.

9. The orthopedic device holder of any one of claim 1 , further comprising a resilient member positioned around a proximal end of the plunger portion and between the locking sleeve and an interior ledge of the body portion.

10. The orthopedic device holder of claim 9 , wherein the resilient member, when the locking lever is in the first position, is in an expanded state.

11. The orthopedic device holder of claim 10 , wherein the resilient member, when the locking lever is in the second position, is in a compressed state.

12. An orthopedic kit, comprising:
the orthopedic device holder of claim 1 ; and
at least one orthopedic device including an engagement end having a tri-lobe cross-sectional shape and a circumferential recess sized and shaped to receive a portion of at least one of the locking bar and the locking sleeve.

13. The orthopedic kit of claim 12 , wherein the orthopedic device includes a plurality of orthopedic devices selected from a group comprising a tibia intramedullary nail, a patella drill guide, a reamer, and a screw driver.

14. An orthopedic device holder, comprising:
a body portion having a proximal end and a distal end, the body portion defining a first bore positioned between the proximal end and the distal end;
a plunger portion extending into a channel of the body portion and defining a second bore, wherein the second bore and first bore have identically shaped cross-sectional geometries with respect to one another such that both the second bore and the first bore are configured to interchangeably receive a portion of an orthopedic device;
a locking bar operably coupled to the body portion and moveable within a slot of the plunger between a locked position and an unlocked position associated with the first bore;
a locking sleeve slidably mounted on the plunger portion and moveable between a locked position and an unlocked position associated with the second bore; and
a locking lever operably coupled to the body portion and configured to move the locking bar and the locking sleeve between the respective locked and unlocked positions to connect and release the orthopedic device from either the first bore or the second bore.

15. The orthopedic device holder system of claim 14 , wherein the first bore and the second bore have a tri-lobe cross-sectional shape, including three substantially flat surfaces.

16. A orthopedic system comprising:
one or more orthopedic devices; and
a orthopedic device holder comprising:
a body portion having a proximal end and a distal end, the body portion defining a first bore positioned between the proximal end and the distal end;
a plunger portion extending into a channel of the body portion and defining a second bore, wherein the second bore and first bore have identically shaped cross-sectional geometries with respect to one another such that both the second bore and the first bore are configured to interchangeably receive a portion of the one or more orthopedic devices;
a locking bar operably coupled to the body portion and moveable within a slot of the plunger between a locked position and an unlocked position associated with the first bore;
a locking sleeve slidably mounted on the plunger portion and moveable between a locked position and an unlocked position associated with the second bore; and
a locking lever operably coupled to the body portion and configured to move the locking bar and the locking sleeve between the respective locked and unlocked positions to connect and release the one or more orthopedic devices from either the first bore or the second bore.

17. The orthopedic system of claim 16 , wherein the one or more orthopedic devices includes a plurality of orthopedic devices selected from a group comprising a tibia intramedullary nail, a patella drill guide, a reamer, and a screw driver.

18. The orthopedic system of claim 16 , wherein the one or more orthopedic devices includes an engagement end having a tri-lobe cross-sectional shape.

19. The orthopedic system of claim 18 , wherein the one or more orthopedic devices includes a circumferential recess sized and shaped to receive a portion of at least one of the locking bar and the locking sle
