Surgical guidance system

Abstract

The invention relates to a surgical guidance system. A surgical guidance system for computer-aided navigation during a spinal surgery is operable to obtain feedback data provided by a distributed networked computer for each patient who has undergone a spinal surgery. The feedback data characterizes a previous patient's spine geometry, characterizes a surgical procedure performed on a previous patient, characterizes an implantation device that implants a previous patient's spine by the surgical procedure, and characterizes a previous patient's outcome of the procedure. The surgical guidance system trains a machine learning model according to the feedback data. A surgical guidance system obtains preoperative data from a distributed network computer that characterizes the spine geometry of a candidate patient planned to perform a surgery, generates a surgical plan for the candidate patient based on the preoperative data processed by a machine learning model, and provides at least a portion of the surgical plan to a display device.

Description

technical field [0001] The present disclosure relates to medical devices and systems, and more particularly, to providing navigation information to users of spinal surgery and / or surgical robots. Background technique [0002] The spine of vertebrates is the axis of bone that provides structural support for the rest of the body. Adjacent vertebrae of the spine are supported by intervertebral discs that serve as mechanical pads that allow controlled movement between the vertebral segments of the axial skeleton. The intervertebral disc is a unique structure composed of three parts: the nucleus pulposus ("nucleus"), the annulus fibrosus ("ring"), and two vertebral endplates. [0003] Spinal discs can become displaced or damaged due to trauma, disease, degenerative defects, or long-term wear and tear. For example, a herniated disc occurs when the annular fibers weaken or tear and the inner tissue of the nucleus permanently bulges. Protruding lumps or "slipped" nuclei can compr...

AI Technical Summary

Problems solved by technology

However, the surgeon's ability to adapt past practice experience to the patient's specific spinal geometry and correction needs is considered when choosing among the numerous combinations of medically recognized spinal surgical procedures and the many available implant types and configurations Inherent limitations exist such that optimal design and implementation types and configurations may not be achieved
