Abstract

A device includes a housing and a locking assembly disposed within a spaced defined by the housing. The housing defines a hole that extends through the housing. The locking assembly is configured to allow the device to slide along an elongate orthopedic device in a first direction and to hinder the device from sliding along an elongate orthopedic device in a second direction that is opposite the first direction.

First claim

What is claimed is:

1. A device, comprising:
a housing including a first portion having a spherical shape and a second portion coupled to the first portion at an intersection, the second portion including a hollow cylindrical wall extending away from the intersection, wherein the hollow cylindrical wall defines an opening sized to receive at least a portion of a digit of a patient therein, the housing further defining a first hole and a second hole, the first hole extending through the housing and defining a first axis, and the second hole extending through the housing and defining a second axis that is not parallel to the first axis; and
a locking assembly disposed within a space defined by the housing, the locking assembly including a locking clamp disposed within a slot defined by the housing and extending across the first hole defined by the housing, the locking clamp pivotally coupled to the housing by a pin that is received through the second hole defined by the housing and through a third hole defined by the locking clamp,
wherein the locking assembly is configured to allow the device to slide along an elongate orthopedic device in a first direction and to hinder sliding in a second direction that is opposite the first direction.

2. The device of claim 1 , wherein the locking assembly includes
a biasing mechanism disposed within a recess defined by the housing.

3. The device of claim 2 , wherein the biasing mechanism includes a compression spring.

4. The device of claim 1 , wherein the locking clamp defines a fourth hole that is positioned along a body of the locking clamp such that it at least partially aligns with the first hole defined by the housing.

5. A method, comprising:
inserting an elongate orthopedic device into at least one bone of a patient, wherein inserting the elongate orthopedic device into at least one bone of the patient includes inserting the elongate orthopedic device into a plurality of bones of an extremity of the patient until a leading end of the elongate orthopedic device emerges from the extremity; and
sliding a first fixation device along a length of the elongate orthopedic device such that the elongate orthopedic device is received within a first hole defined by a housing of the first fixation device, the first fixation device including a locking assembly disposed within a space defined by the housing, the locking assembly including a locking clamp disposed within a slot defined by the housing and extending across the first hole defined by the housing, the locking clamp pivotally coupled to the housing by a pin that is received through a second hole defined by the housing and through a third hole defined by the locking clamp, the second hole extending through the housing and defining a second axis that is not parallel to a first axis defined by the first hole;
sliding a second fixation device along a length of the elongate orthopedic device such that the elongate orthopedic device is received within a hole defined by a housing of the second fixation device; and
wherein the locking assembly of the first fixation device is configured to allow the first fixation device to slide along the elongate orthopedic device in a first direction and to hinder sliding in a second direction that is opposite the first direction.

6. The method of claim 5 , further comprising removing a portion of the elongate orthopedic device that extends from the first fixation device.

7. The method of claim 5 , wherein the locking assembly of the first fixation device includes
a biasing mechanism disposed within a recess defined by the housing of the first fixation device.

8. The method of claim 7 , wherein the elongate orthopedic device is received within a fourth hole defined by the locking clamp of the first fixation device as the first fixation device slides along the length of the elongate orthopedic device.

9. The method of claim 8 , wherein the biasing mechanism presses against a body of the locking clamp when the elongate orthopedic device is received within the fourth hole defined by the locking clamp of the first fixation device to hinder the first fixation device from sliding along the elongate orthopedic device in the second direction.

10. The method of claim 9 , wherein the biasing mechanism includes a compression spring.

11. The method of claim 5 wherein the second fixation device includes a locking assembly disposed within a space defined by the housing, and wherein the locking assembly of the second fixation device is configured to allow the second fixation device to slide along the elongate orthopedic device in the second direction and to hinder sliding in first direction that is opposite the second direction.

12. The method of claim 5 , wherein the housing of the first fixation device includes
a first portion having a spherical shape; and
a second portion coupled to the first portion at an intersection, the second portion including a hollow cylindrical wall extending away from the intersection.

13. The method of claim 12 , wherein the first fixation device is slid along the elongate orthopedic device until a portion of an extremity of the patient contacts the hollow cylindrical wall.

14. The method of claim 12 , wherein the extremity is a toe.

15. A method, comprising:
inserting an elongate orthopedic device into at least one bone of a patient;
sliding a first fixation device along a length of the elongate orthopedic device such that the elongate orthopedic device is received within a first hole defined by a housing of the first fixation device, the first fixation device including a locking assembly disposed within a space defined by the housing; and
sliding a second fixation device along a length of the elongate orthopedic device such that the elongate orthopedic device is received within a hole defined by a housing of the second fixation device,
wherein the locking assembly of the first fixation device is configured to allow the first fixation device to slide along the elongate orthopedic device in a first direction and to hinder sliding in a second direction that is opposite the first direction.
