Abstract

A surgical instrument assembly may include a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The processor can be configured to determine a position of the medical imaging device, from which the medical imaging device can generate an X-ray image that includes holes of an intramedullary nail shown as circles, for instance perfect circles. In an example, the processor identifies the intramedullary nail, so as to determine an intramedullary nail identity, and determines the position of the medical imaging device based on a portion of at least two locking holes of the intramedullary nail and based on the intramedullary nail identity.

First claim

What is claimed:

1. A method for determining an orientation for drilling a hole for a locking screw to secure an intramedullary nail to a bone, the method comprising the steps of:
receiving, via a communications channel, a first image of the bone and a portion of the intramedullary nail within the bone, the first image generated by a medical imaging device while the medical imaging device is in a first position, the first image including a first visual perspective of at least a portion of at least two locking holes defined by the intramedullary nail;
identifying the intramedullary nail from a plurality of intramedullary nails so as to determine an intramedullary nail identity that is associated with physical characteristics of the intramedullary nail;
retrieving the physical characteristics of the intramedullary nail based on the intramedullary nail identity;
based on the first visual perspective of at least the portion of the at least two locking holes, and based on the physical characteristics of the intramedullary nail, determining a second position for the medical imaging device; and
causing the medical imaging device to be in the second position, wherein, when the medical imaging device generates a second image while the medical imaging device is in the second position, the second image includes a second visual perspective of the at least two locking holes, the second visual perspective defining circles that correspond to respective perimeters of the at least two locking holes.

2. The method as recited in claim 1 , wherein the first visual perspective defines ellipses or lenses that correspond to respective perimeters of the at least two locking holes.

3. The method as recited in claim 1 , the method further comprising:
based on the first visual perspective of the at least two locking holes, and based on the physical characteristics of the intramedullary nail, determining a third position for the medical imaging device,
wherein, when the medical imaging device generates a third image while the medical imaging device is in the third position, the third image includes a third visual perspective of a third locking hole of the intramedullary nail, the third locking hole not visible in the first image, the third visual perspective defining a circle that corresponds to a perimeter of the third locking hole.

4. The method as recited in claim 1 , wherein the first image is a first electromagnetic radiation image, and the second image is a second electromagnetic radiation image.

5. The method as recited in claim 1 , wherein causing the medical imaging device to be in the second position is such that the medical imaging device defines a direction of electromagnetic radiation travel that is substantially perpendicular to a plane defined by the perimeter of the circles of the second visual perspective of the at least two locking holes.

6. The method as recited in claim 5 , further comprising a motion sensor determining an orientation of the direction of electromagnetic radiation travel, so as to calibrate an accelerometer with the direction of electromagnetic radiation travel from an electromagnetic radiation generator to an electromagnetic radiation receiver of the medical imaging device.

7. The method as recited in claim 5 , further comprising determining adjustment coordinates based on the first and second positions of the medical imaging device, the adjustment coordinates indicating how the direction of electromagnetic travel is adjusted to arrive at the second position from the first position.

8. The method as recited in claim 1 , wherein the portion of the two locking holes shown in the first image is less than 30% of the two locking holes.

9. A method of drilling a hole for a locking screw to secure an intramedullary nail to a bone, the method comprising:
identifying the intramedullary nail from a plurality of intramedullary nails so as to determine an intramedullary nail identity that is associated with physical characteristics of the intramedullary nail;
causing a medical imaging device to be in a first position relative to the intramedullary nail;
while the medical imaging device is in the first position, generating a first image of the bone, the first image including a portion of the intramedullary nail, the portion of the intramedullary nail including a first visual perspective of at least a portion of at least one locking hole defined by the intramedullary nail;
based on the first visual perspective of at least the portion of the at least one locking hole, and based on the physical characteristics of the intramedullary nail that are associated with the intramedullary nail identity, determining a second position of the medical imaging device relative to the intramedullary nail;
causing the medical imaging device to be in the second position relative to the intramedullary nail; and
while the medical imaging device is in the second position, generating a second image of the bone,
wherein the second image includes a second visual perspective of the at least one locking hole, and the second visual perspective defines at least one circle that corresponds to a perimeter of the at least one locking hole.

10. The method as recited in claim 9 , the method further comprising:
causing the medical imaging device to be in the second position such that the medical imaging device defines a direction of electromagnetic radiation travel that is substantially perpendicular to a plane defined by the perimeter of the at least one circle of the second visual perspective of the at least one locking hole.

11. The method as recited in claim 10 , further including a motion sensor determining an orientation of the direction of electromagnetic radiation travel, so as to calibrate an accelerometer with the direction of electromagnetic radiation travel from an electromagnetic radiation generator to an electromagnetic radiation receiver of the medical imaging device.

12. The method as recited in claim 10 , the method further comprising:
drilling the hole along the direction of electromagnetic radiation travel defined by the medical imaging device when the medical imaging device is in the second position.

13. The method as recited in claim 9 ,
wherein the second position is only determined based on the first image and the physical characteristics of the intramedullary nail, which are based on the intramedullary nail identity, and
wherein the at least one locking hole comprises two locking holes.

14. The method as recited in claim 9 , the method further comprising:
displaying an indication of the second position; and
positionally adjusting the medical imaging device from the first position to the second position.

15. A method for determining an orientation for drilling a hole for a locking screw to secure an intramedullary nail to a bone, the method comprising the steps of:
receiving, via a communications channel, a first image of the bone and a portion of the intramedullary nail within the bone, the first image generated by a medical imaging device while the medical imaging device is in a first position, the first image including a first visual perspective of at least a portion of at least one locking hole defined by the intramedullary nail;
retrieving physical characteristics of the intramedullary nail;
based on the first visual perspective of the least one locking hole, and based on the physical characteristics of the intramedullary nail, determining a second position for the medical imaging device;
causing the medical imaging device to be in the second position, wherein, when the medical imaging device generates a sec
