Abstract
A holographic augmented reality ultrasound needle guide system and method includes an augmented reality display such as a headset wearable by a user. The augmented reality display is configured to depict a virtual ultrasound image. The augmented reality display is further configured to allow a user to select a desired reference point on the virtual ultrasound image. The system is configured to depict a holographic needle guide based on the selection of the desired reference point. The system is also configured to adjust a trajectory of the holographic needle guide to avoid intersecting undesired anatomical structures. The augmented reality display is further configured to stamp the holographic needle guide into a selectively locked trajectory and position.
Core Innovation
The invention provides a system for guiding percutaneous insertion of a needle by a user into a patient. An augmented reality display depicts a virtual ultrasound image of a portion of the patient and depicts a holographic needle guide on the patient based upon selection of a reference point in the virtual ultrasound image. The holographic needle guide displays a trajectory for the needle to the reference point, where the trajectory is independent of a position of the needle, and is adjustable in real-time during the procedure by at least one of the user and a remote user.
After adjustment, the holographic needle guide is configured to be stamped in a virtually locked position. The method includes selecting the reference point in the virtual ultrasound image, displaying the holographic needle guide on the patient based upon the selection, adjusting an angle of trajectory associated with the holographic needle guide, stamping in augmented reality the holographic needle guide in a desired position, and percutaneously inserting the needle along a trajectory of the holographic needle guide.
The invention includes a physical ultrasound probe and a physical needle insertion guide disposed on the physical ultrasound probe to indicate predetermined insertion points. The physical needle insertion guide is a physical template configured to be placed on the patient, and the augmented reality display is directed by a computer to display the holographic needle guide on the patient based upon the selection of the reference point in the virtual ultrasound image. Optional tracking means can provide enhanced visualization of at least one of the patient’s anatomy and the needle, and the display can provide a holographic error bar/alert when needle deviation exceeds a variance threshold.
Claims Coverage
The document provides two independent claims covering a guiding system and a corresponding surgical method. Each claim includes multiple core inventive features relating to augmented reality display of a virtual ultrasound image, a holographic needle guide independent of needle position, reference point selection, real-time trajectory adjustment, and virtual stamping/locking for the guided insertion flow.
Augmented reality depiction of virtual ultrasound and holographic needle guide based on reference point selection
An augmented reality display depicts a virtual ultrasound image of a portion of the patient and depicts a holographic needle guide on the patient based upon selection of a reference point in the virtual ultrasound image.
Holographic trajectory independent of needle position with real-time adjustability by user or remote user
The holographic needle guide displays a trajectory for the needle to the reference point wherein the trajectory is independent of a position of the needle, and wherein the holographic needle guide is adjustable in real-time during the procedure by at least one of the user and a remote user.
Virtually locked stamping of the holographic needle guide after adjustment
After adjustment the holographic needle guide is configured to be stamped in a virtually locked position.
Physical ultrasound probe with physical needle insertion guide template indicating predetermined insertion points
A physical ultrasound probe and a physical needle insertion guide disposed on the physical ultrasound probe configured to indicate at least one predetermined insertion point on the patient, wherein the physical needle insertion guide is a physical template configured to be placed on the patient.
Percutaneous insertion of the needle along the holographic trajectory after reference selection, guide display, angle adjustment, and stamping
The method includes selecting the reference point in the virtual ultrasound image, displaying the holographic needle guide on the patient based upon the selection, adjusting an angle of trajectory associated with the holographic needle guide, stamping in augmented reality the holographic needle guide in a desired position, and percutaneously inserting the needle along a trajectory of the holographic needle guide.
Across both independent claims, the inventive coverage centers on using an augmented reality display to present a virtual ultrasound image and a holographic needle guide defined by a user-selected reference point, with a trajectory that is independent of needle position and adjustable in real time by a user and/or a remote user, followed by stamping the guide in a virtually locked position before percutaneous needle insertion along the guided trajectory.
