Abstract

Claims (81)

1 . A medical device, comprising:

a first end having a first aperture, a first biasing member, a second aperture, and a second biasing member;

each of the first aperture and the second aperture to receive a portion of a bone component;

the first biasing member including a spring-loaded locking cam having a lever arm portion and a body portion, the lever arm portion to cause the body portion to pivot between a first position, with the body portion enclosing the first aperture to fix the bone component within the first aperture, and a second position, with the body portion disposed apart from the first aperture to allow removal of the bone component from the first aperture;

a second end having a handle to apply force to the bone component; and

the handle including a torque reduction mechanism, the torque reduction mechanism including:

a fastener; and

a pin coupled to the fastener, the pin to engage with the handle.

2 . The medical device of claim 1 , comprising:

the fastener to engage with a linkage mechanism; and

the bone component comprises a second pin to be inserted through a portion of a bone.

3 . The medical device of claim 1 , comprising:

a first arm that extends between the first end and the second end;

a second arm that extends between the first end and the second end; and

the handle to apply the force to the bone component by driving the first arm and the second arm in opposing directions.

4 . The medical device of claim 1 , comprising:

the first biasing member biased towards the first position such that the body portion of the first biasing member is configured to at least partially contact the bone component in the first position.

5 . The medical device of claim 1 , comprising:

a first arm that extends between the first end and the second end;

a second arm that extends between the first end and the second end; and

at least one of the first arm or the second arm includes a plurality of ribs.

6 . The medical device of claim 1 , comprising:

at least one disposable material; and

at least one injection molded plastic material.

7 . The medical device of claim 1 , comprising:

at least one disposable material;

at least one injection molded plastic material; and

at least one rib formed within the at least one injection molded plastic material.

8 . The medical device of claim 1 , comprising:

at least one of a portion of the handle or a portion of an arm that extends between the first end and the second end includes a textured material.

9 . The medical device of claim 1 , comprising:

the fastener including a hexagonal head defining a flat surface; and

the torque reduction mechanism further including a spring to engage with the flat surface of the hexagonal head.

10 . The medical device of claim 1 , comprising:

a first arm that extends between the first end and the second end;

the first arm including a front surface, a rear surface, and a slot extending from the first aperture and between the front surface and the rear surface; and

the body portion of the first biasing member at least partially disposed within the slot such that the body portion is integrated into the first arm.

11 . The medical device of claim 1 , comprising:

a first arm that extends between the first end and the second end;

the body portion of the first biasing member pivotably coupled with the first arm by a pivot point; and

the pivot point offset from a center point of the body portion.

12 . A method, comprising:

providing a medical device including a first end having a first aperture, a first biasing member, a second aperture, and a second biasing member and a second end having a handle, the first biasing member and the second biasing member each including a spring-loaded locking cam having a lever arm portion and a body portion, the lever arm portion to cause the body portion to pivot between a first position, with the body portion closing the first or second aperture to fix a bone component within the first or second aperture, and a second position, with the body portion disposed apart from the first or second aperture to allow removal of the bone component from the first or second aperture;

actuating the lever arm portions of the first biasing member and the second biasing member to pivot the body portions to the second position;

receiving, by the first aperture, a first portion of the bone component;

receiving, by the second aperture, a second portion of the bone component;

releasing the lever arm portions of the first biasing member and the second biasing member to pivot the body portions to the first position; and

actuating the handle to apply force to the first portion and the second portion of the bone component;

the handle including a torque reduction mechanism, the torque reduction mechanism including:

a fastener; and

a pin coupled to the fastener, the pin to engage with the handle.

13 . The method of claim 12 , comprising:

the fastener to engage with a linkage mechanism; and

the bone component comprises a second pin to be inserted through a portion of a bone.

14 . The method of claim 12 , comprising:

a first arm that extends between the first end and the second end;

a second arm that extends between the first end and the second end; and

actuating the handle includes driving the first arm and the second arm in opposing directions.

15 . The method of claim 12 , comprising:

the first biasing member biased towards the first position such that the body portion of the first biasing member is configured to at least partially contact the bone component in the first position.

16 . The method of claim 12 , comprising:

a first arm that extends between the first end and the second end;

a second arm that extends between the first end and the second end; and

at least one of the first arm or the second arm includes a plurality of ribs.

17 . The method of claim 12 , comprising:

disposing the medical device.

18 . The method of claim 12 , comprising:

the fastener including a hexagonal head defining a flat surface; and

the torque reduction mechanism further including a spring to engage with the flat surface of the hexagonal head.

19 . A method, comprising:

providing a medical device, the medical device including:

a first end having a first aperture, a first biasing member, a second aperture, and a second biasing member;

each of the first aperture and the second aperture to receive a portion of a bone component;

the first biasing member including a spring-loaded locking cam having a lever arm portion and a body portion, the lever arm portion to cause the body portion to pivot between a first position, with the body portion closing the first aperture to fix the bone component within the first aperture, and a second position, with the body portion disposed apart from the first aperture to allow removal of the bone component from the first aperture;

a second end having a handle to apply force to the bone component; and

the handle including a torque reduction mechanism, the torque reduction mechanism including:

a fastener; and

a pin coupled to the fastener, the pin to engage with the handle.

20 . The method of claim 19 , comprising:

the fastener to engage with a linkage mechanism; and

the bone component comprises a second pin to be inserted through a portion of a bone.
