1. A device for separating a bone fixation device from an introducer comprising:
- a cutting mechanism having a tubular shape and at a distal end slotted to form flexible arm sections, each flexible arm section having an outer radial surface portion at a distal end;
a functional portion having an outer shaft surrounding a portion of the cutting mechanism and controlling operation of the cutting mechanism; and
a control portion having an actuating mechanism for initiating activation of the outer shaft, wherein a distal end of the control portion engages the outer shaft of the functional portion, andwherein activation of the actuating mechanism translates the outer shaft to move from a first position distally along the cutting mechanism to a second position over the outer radial surface portions,(a) in the first position of the outer shaft, the outer radial surface portions are separated by a first distance;
(b) in the second position of the outer shaft, the outer radial surface portions are separated by a second distance, wherein the second distance is less than the first distance, to push each flexible arm section of the cutting mechanism toward one another to separate the bone fixation device from the introducer in a void of a bone.

15. A device for separating a bone fixation device from an introducer in a void of a bone, the device comprising:
-
a cutting mechanism having a planar shape and a blade at an distal end of the cutting mechanism; a functional portion having the cutting mechanism positioned to slide along a bottom surface of a housing, the housing sized and shaped for positioning around the introducer; a control portion having a first section attached to a connector for engaging the cutting mechanism; and an actuating mechanism for initiating activation of the cutting mechanism for translating the cutting mechanism to linearly move from a first position distally along the bottom surface of the housing to a second position, (a) in the first position of the cutting mechanism, the blade is positioned within sidewalls of the housing, (b) in the second position of the cutting mechanism, the blade is positioned with a portion of the blade beyond a distal end of the sidewalls of the housing, thereby pushing the portion of the blade to separate the bone fixation device from the introducer in the void of the bone. - View Dependent Claims (16, 17, 18, 19, 20)
