1. A bone fusion device for insertion into a desired location comprising:
a body having an interior cavity;
a plate having a first end that is pivotably coupled to a back end of the body at a pivot point, and a second end that is opposite the first end, wherein a top surface of the plate is curved between the first end and the second end and the plate is configured to selectively move from a retracted position having the second end within the interior cavity to an extended position having the second end outside of the interior cavity by pivoting about the pivot point;
a positioning component located partially within the interior cavity, wherein the positioning component has a central axis and is configured to rotate about the central axis while within the interior cavity; and
an extending block coupled with the positioning component and configured to slide within the interior cavity of the body based on rotation of the positioning component thereby causing the plate to pivot about a pivot axis between the retracted position and the extended position;
wherein when in the retracted position, in a direction perpendicular to the central axis and the pivot axis, a minimum distance between the central axis and the top surface of the plate at the second end is smaller than a minimum distance between the central axis and the top surface of the plate at the first end.
