US 11,112,770 B2 · Systems and methods for assisting a surgeon and producing patient-specific medical devices

Abstract

Systems and methods for assisting a surgeon with implant during a surgery are disclosed. A method includes defining areas of interest in diagnostic data of a patient and defining an implant type. Post defining the areas of interest, salient points are determined for the areas of interest. Successively, an XZ angle, an XY angle, and a position entry point for an implant are determined based on the salient points of the areas of interest. In spinal procedures, a maximum screw diameter and a length of the spinal screw are successively determined based on the salient points. Based on determined length and diameter, a spinal screw and a matching screw guide is determined. Thereafter, the spinal screw and the screw guide is printed using a Three-Dimensional (3D) printer. Such printed spinal screw and screw guide could be used by the surgeon during the spinal surgery.

A non-transitory computer-readable storage medium storing instructions that, when executed by a computing system, cause the computing system to perform operations comprising:

receiving diagnostic data of a patient, the diagnostic data including image data of the patient's spine;
analyzing the diagnostic data to identify one or more spinal segments for a surgery to be performed;
using at least one trained machine learning model to design, based on the one or more areas of interests and/or the diagnostic data, a first patient-specific implant and a second patient-specific implant configured to be spaced apart from the first patient-specific implant when implanted at the one or more spinal segments, wherein designing the first patient-specific implant and the second patient-specific implant includes specifying a first configuration of the first patient-specific implant and a second configuration of the second-patient specific implant;
generating a virtual model of the first patient-specific implant and the second patient-specific implant;
and
