Appl. No.:

13/041990

Inventors:

Lu Li - Sunnyvale CA, US

Assignee:

EIGEN, INC. - Grass Valley CA

International Classification:

G06F 19/00

US Classification:

702 94

Abstract:

This application presents a new system and method for image acquisition of internal human tissue, including but not limited to the prostate, as well as a system and method for the guidance and positioning of medical devices relative to the internal tissue. In the presented systems and methods, ultrasound scanned data (e.g., 2-D B-mode images) are acquired freehand absent a mechanical armature that constrains an ultrasound acquisition probe in a known spatial framework. To allow for reconstruction of the scanned data into a 3-D image, multiple tracker sensors that provide position/location information are used with a freehand acquisition probe (e.g., handheld ultrasound probe). The position of such tracker sensors can be calculated when disposed in an electromagnetic field.

Abstract:

Methods, devices and systems for the planning and execution of computer-assisted robotic surgery are provided. The methods include methods to collect information about bones and prostheses, use the information to create virtual models and simulations, optionally receive input based on user discretion in generating the cut file, and to generate instruction for the execution of cut paths during the surgery. The system and devices include computers and peripherals and set-ups to link the components together into functional systems.

Abstract:

Described herein are systems and methods for creating a custom registration guide. In general, the methods may include receiving scan data of a patient's bone; creating instructions based on the scan data for creating a three-dimensional surface model of the patient's bone; and moving a plurality of moveable elements, coupled to the adjustable model, based on the instructions. The method may further include the steps of placing a malleable registration guide onto the adjustable model and shaping the registration guide to fit to the adjustable model. The method may further include the step of intraoperatively determining the location of a patient's bone using the custom registration guide. The step of determining the location of the patient's bone may include the steps of coupling the registration guide and fiducial markers to the patient's bone.
