OPTICAL TARGETING AND VISUALIZATION OF TRAJECTORIES

摘要

Enhanced targeting systems and methods may be used to visualize trajectories for surgical instruments. Such a targeting system may have a fixture that can be secured at a predetermined location relative to a patient, a first light source attached to the fixture, and a second light source attached to the fixture. The first light source may project first light along a first plane, and the second light source may project second light along a second plane nonparallel to the first plane. At an intersection of the first and second planes, the first light and the second light may cooperate to produce a targeting line that indicates the desired trajectory. A controller may be connected to first and second sets of motors to orient the first and second light sources, respectively. The targeting line may be projected on a visualization aid that guides the surgical instrument along the trajectory.

主权项

1. A targeting system for providing visualization of a trajectory for a medical instrument, the targeting system comprising:
a fixture comprising a first attachment feature that secures the fixture at a predetermined location relative to a patient; a first light source attached to the fixture, wherein the first light source projects first light along a first plane; and a second light source attached to the fixture, wherein the second light source projects second light along a second plane nonparallel to the first plane such that, at an intersection of the first plane with the second plane, the first light and the second light cooperate to produce a first targeting line that indicates the trajectory.
