Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical systems face challenges in accurately guiding surgical instruments during minimally invasive procedures due to potential fiducial migration, leading to sub-optimal results.
Innovation Solution
The system integrates a software application that processes medical images to develop a 3D model of a patient's anatomical structure, superimposes critical structures, and provides real-time guidance to surgical instruments, enhancing precision and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fiducial markers are implanted to guide surgical instruments, then the location of the lesion can be identified, but the fiducial may migrate within the tissue leading to inaccurate identification
Solution Approach 1:
The system creates a virtual copy of the patient's anatomy using 3D reconstruction from medical images. This virtual model includes the lesion and surrounding structures, allowing surgeons to navigate and identify targets without relying on physical fiducial markers that can migrate. The virtual model serves as a stable, accurate reference throughout the procedure.
Solution Approach 2:
The patent replaces the mechanical fiducial marker system with an image-based navigation system. Instead of using physical markers implanted in tissue, the system uses processed medical images and 3D reconstructions to provide spatial reference, eliminating the migration problem inherent in mechanical fiducials.
2Object-affected harmful factors
If minimally invasive surgical techniques are used, then tissue trauma is minimized and recovery is faster, but accurate guidance of surgical instruments becomes more difficult
Solution Approach 1:
The system transitions from 2D medical images to 3D reconstructed models, adding a spatial dimension that enhances instrument guidance. The 3D model provides depth perception and spatial relationships that are difficult to obtain from 2D images alone, improving navigation accuracy while maintaining minimally invasive benefits.
Solution Approach 2:
The patent introduces a computer-based image processing and 3D reconstruction system as an intermediary between the surgeon and the surgical field. This intermediary provides enhanced visualization and guidance information, allowing accurate instrument placement through small incisions without direct visual access to the surgical site.
3Measurement precision
If extensive medical imaging and 3D modeling are performed, then surgical planning and guidance accuracy improve, but the complexity of the system and data processing increases
Solution Approach 1:
The system integrates multiple functions into a unified platform: importing various medical image formats, performing 3D reconstruction, enabling surgical planning, providing intraoperative guidance, and supporting multiple surgical instruments. This multi-functional approach reduces the need for separate systems and simplifies the overall workflow despite the complexity of individual components.
Data Source
AI summary
A method of performing a surgical procedure includes storing a software application on a memory associated with a computer, which when executed by a processor causes the software application to develop a model of a patient's anatomical structure, process images of the patient's anatomy, display the images of the patient's anatomy on a user interface associated with the computer, superimpose critical structures within the patient over the displayed images of the patient's anatomy, determine a location within the patient's body cavity where the images of the patient's anatomy were taken, and display the model of the patient's anatomical structure on the user interface, the displayed model indicating the determined location where the images of the patient's anatomy were taken.
