Abstract
Disclosed herein are device and methods for determining an orientation of an instrument for inserting a medical device in a bone. One such method includes simulating an insertion point and an orientation of a simulated surgical hardware installation on a diagnostic representation of the bone, and then using an electronic device to align an instrument for inserting a surgical hardware installation at a desired orientation through an insertion point of the bone by indicating when an orientation of the electronic device is within a threshold of the simulated orientation.
Claims23
A method comprising:
- simulating an insertion point and an orientation of a simulated surgical hardware installation on a diagnostic representation of a bone;
- and
- using an electronic device to align an instrument for inserting a surgical hardware installation at a desired orientation through an insertion point of the bone by indicating when an orientation of the electronic device is within a threshold of the simulated orientation.
An apparatus for determining orientation of an instrument for inserting a medical device in a bone, the apparatus comprising:
- an electronic device comprising:
- an orientation sensor;
- a processor configured to:
- simulate insertion of the medical device in an image of the bone to determine a desired insertion angle of the medical device relative to a plane of the bone;
- determine an orientation of the electronic device relative to the plane using the orientation sensor;
- output a notification when the orientation of the electronic device is such that the electronic device is positioned adjacent the desired angle of the medical device relative to the plane.
A method for verifying an insertion angle of an instrument for determining a correct angle for a pedicle screw in a vertebra comprising:
- aligning an axis of an apparatus with at least one of a sagittal plane, transverse plane, and coronal plane of the vertebra in a representation thereof;
- capturing an image of the representation of the vertebra;
- generating an angle-indicative line on a display, wherein the angle-indicative line adjusts in response to rotation and orientation of the apparatus and provides a notification when the apparatus is at the correct angle, the correct angle being a desired angle between the axis of the apparatus and at least one of the sagittal plane, transverse plane, and coronal plane.
A system for indicating an insertion sagittal angle of a tract for receiving a pedicle screw in a vertebra, the system comprising:
- an image acquisition unit;
- an orientation sensor;
- a display;
- a processor configured to:
- obtain an image of a cross sectional view in a transverse plane of the vertebra, using the image acquisition unit;
- measure orientation of the system and calibrate the orientation to align with a sagittal plane, transverse plane, or coronal plane of the vertebra;
- receive definitions of an insertion sagittal angle, transverse angle, or coronal angle of the tract and an initial position thereof relative to the vertebra;
- and
- generate an angle-indicative line on the display, wherein the angle-indicative line rotates in response to rotation of the system, and provides a notification when at least a portion of the system approximately forms the insertion sagittal angle, transverse angle, or coronal angle between an axis of the apparatus and the sagittal plane, transverse plane, or coronal plane of the vertebrae.
