US 11,589,927 B2 · Surgical navigation system and method

Abstract

The present disclosure relates to a surgical navigation system for the alignment of a surgical instrument and methods for its use, wherein the surgical navigation system may comprise a head-mounted display comprising a lens. The surgical navigation system may further comprise tracking unit, herein the tracking unit may be configured to track a patient tracker and/or a surgical instrument. Patient data may be registered to the patient tracker. The surgical instrument may define an instrument axis. The surgical navigation system may be configured to plan one or more trajectories based on the patient data. The head-mounted display may be configured to display augmented reality visualization, including an augmented reality position alignment visualization and/or an augmented reality angular alignment visualization related to the surgical instrument on the lens of the head-mounted display.

Dependent claims

A head-mounted display system for use with a surgical navigation system, a patient tracker trackable by the surgical navigation system, and a surgical instrument trackable by the surgical navigation system, said head-mounted display system comprising:

a lens;
and
a controller configured to display an augmented reality position alignment visualization as two axis-aligned deviation vectors comprising a decomposition of a distance vector from a target point on a target trajectory axis to the surgical instrument on said lens.

A method of displaying surgical navigation information using a head-mounted display system including a surgical navigation system and a surgical instrument having a tip and at least partially defining an instrument axis in view of a surgical plan including a target trajectory axis, said method comprising:

displaying an augmented reality position alignment visualization comprising two axis-aligned deviation vectors on a head-mounted display, said two-axis aligned deviation vectors comprising a first deviation vector and a second deviation vector wherein the first deviation vector and second deviation vector are representative of a decomposition of a distance vector from a point on the target trajectory axis to the tip of the surgical instrument;
and
updating the augmented reality position alignment visualization displayed on the head-mounted display to indicate a relative location of the surgical instrument to the target trajectory axis from the perspective of the head-mounted display.

Dependencies are inferred from the claim text.
