a medical alignment device that includes:

an orientation sensor;

a processor configured to:

simulate a positioning of the medical tool using at least one image of a bone of the patient to determine a desired alignment angle of the medical tool relative to the bone;

determine an orientation of the medical alignment device using the orientation sensor;

and

output a notification when the orientation of the medical alignment device is such that the medical alignment device is positioned at or about the desired alignment angle of the medical tool relative to the bone, wherein the notification includes one or more of a sound, a vibration, or a graphical indicator;

and

an attachment apparatus to attach the medical alignment device to the medical tool, wherein the attachment apparatus includes:

the first and second finger profiles each comprising at least two concave surfaces shaped to receive at least two fingers of a user when held, wherein when the medical alignment device is securably received in the monolithic upper portion, a clamping force is produced between the first and second side walls which compresses the medical alignment device and slightly bends the attachment apparatus;

and

an alignment support with an opening aligned parallel or perpendicular relative to the base wall, and wherein the opening of the alignment support is configured to align with a portion of the medical tool, and wherein the medical alignment device provides the notification when the medical alignment device aligned with the medical tool is provided at the desired alignment angle.

2. The system for aligning a medical tool to a desired orientation of claim 1 , wherein the medical alignment device is operable to provide the desired alignment angle at a three-dimensional alignment angle relative to an insertion location.

3. The system for aligning a medical tool to a desired orientation of claim 1 , wherein the second side wall and the first side wall include one or more engagement protrusions to increase friction forces against the medical alignment device.

4. The system for aligning a medical tool to a desired orientation of claim 1 , wherein the base wall and the first side wall form a matching profile to at least a first surface and a second surface of the medical alignment device.

5. The system for aligning a medical tool to a desired orientation of claim 1 , wherein the medical tool is one or more of a drill, a device to create a pilot hole in a bone, a gear shifter for creating a pilot hole in a bone, a driving mechanism, a screw, a pedicle screw, and an alignment guide.

6. The system for aligning a medical tool to a desired orientation of claim 1 , wherein the alignment support of the attachment apparatus aligns with the portion of the medical tool at different cylindrical locations of the medical tool along a longitudinal axis of the medical tool.

7. A system for aligning a medical tool to a desired orientation relative to a patient, the system comprising:

a medical alignment device that includes:

an orientation sensor;

a processor configured to:

simulate a positioning of the medical tool using at least one image of a bone of the patient to determine a desired alignment angle of the medical tool relative to the bone;

determine an orientation of the medical alignment device using the orientation sensor;

and

output a notification when the orientation of the medical alignment device is such that the medical alignment device is positioned at or about the desired alignment angle of the medical tool relative to the bone,

wherein the notification includes one or more of a sound, a vibration, or a graphical indicator;

and

an attachment apparatus to attach the medical alignment device to the medical tool, wherein the attachment apparatus includes:

a monolithic upper portion configured to securably receive the medical alignment device, the monolithic upper portion defined by a first side wall comprising a first finger profile, a second side wall comprising a second finger profile, a base wall, and a main support surface,

the main support surface having a first end and a second end;

the base wall including a base alignment surface configured to be adjacent a first portion of the medical alignment device, the base wall extending perpendicularly from the main support surface along the first end;

the first side wall including a side alignment surface configured to be adjacent a second portion of the medical alignment device, the first side wall extending perpendicularly from the main support surface and between the first end and the second end of the main support surface;

the second side wall including a side alignment surface configured to be adjacent a third portion of the medical alignment device; the second side wall extending perpendicularly from the main support surface and between the first end and the second end of the main support surface; and

the first and second finger profiles each comprising at least two concave surfaces shaped to receive at least two fingers of a user when held,

wherein when the medical alignment device is securably received in the monolithic upper portion, a clamping force is produced between the first and second side walls which compresses the medical alignment device and slightly bends the attachment apparatus; and

an alignment support attached to the base wall, the alignment support including an opening aligned parallel or perpendicular relative to the base wall, and wherein the opening of the alignment support is configured to align with a portion of the medical tool, and wherein the medical alignment device provides the notification when the medical alignment device aligned with the medical tool is provided at the desired alignment angle.

8. The system for aligning a medical tool to a desired orientation of claim 7 , wherein the alignment support has a fixed orientation with respect to the base wall.

9. The system for aligning a medical tool to a desired orientation of claim 7 ,

wherein the base alignment surface and each side alignment surface form a continuous surface.

10. The system for aligning a medical tool to a desired orientation of claim 7 , wherein the medical alignment device includes a front side with a screen and a rear side opposite the front side, and wherein the main support surface is configured to abut the rear side.

11. A system for aligning a medical tool to a desired orientation relative to a patient, the system comprising:

a medical alignment device that includes:

an orientation sensor;

a processor configured to:

simulate a positioning of the medical tool using at least one image of a bone of the patient to determine a desired alignment angle of the medical tool relative to the bone;
