Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Minimally invasive surgical procedures face challenges in accurately identifying and accessing target tissue within the patient anatomy due to limitations in pre-operative imaging, shifting anatomy, and the need for real-time navigation and treatment planning.
Innovation Solution
A medical system equipped with localization and imaging sensors that create and update models of the patient anatomy, allowing for precise navigation and treatment planning, including the use of position, orientation, and shape sensors, and imaging data to guide medical instruments to target tissues while avoiding sensitive areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If pre-operative imaging is used to plan surgery, then treatment planning can be performed in advance, but the anatomy may shift during surgery making the pre-operative model inaccurate
Solution Approach 1:
The system transitions from static pre-operative imaging to dynamic real-time imaging. The imaging sensor continuously captures anatomical data during the surgical procedure, allowing the model to update and adapt to anatomical shifts as they occur, thereby maintaining measurement precision throughout the procedure.
Solution Approach 2:
The system performs preliminary actions by creating an initial anatomical model from pre-operative imaging data, which provides a starting point for treatment planning. This preliminary model is then refined and updated in real-time during surgery, combining the benefits of advance planning with intraoperative accuracy.
2Object-affected harmful factors
If minimally invasive techniques are used to reduce tissue damage, then patient recovery time is reduced, but accurate identification and access to target tissue becomes more difficult
Solution Approach 1:
The system replaces mechanical visual inspection and manual navigation with sensor-based detection and image-guided navigation. Localization sensors and imaging sensors provide real-time feedback on device position and anatomical structures, enabling accurate target tissue identification through natural orifices or small incisions without requiring large surgical openings for direct visualization.
Solution Approach 2:
The system introduces imaging sensors and localization sensors as intermediaries between the surgeon and the target tissue. These sensors act as mediators that provide indirect visualization and positioning information, allowing the surgeon to navigate to and treat target tissue accurately through minimally invasive access points.
3Measurement precision
If real-time imaging and model updating are implemented to improve navigation accuracy, then the complexity of the medical system increases
Solution Approach 1:
The medical device integrates multiple functions into a single system: the imaging sensor both visualizes anatomical structures and provides localization data, while the processor both creates the initial model and performs real-time updates. This multi-functionality reduces the need for separate dedicated components, managing system complexity while maintaining high navigation accuracy.
Solution Approach 2:
The system merges the imaging functionality with the localization functionality into an integrated system. The same imaging sensor that captures anatomical images also provides data for determining device position and updating the anatomical model, combining multiple functions that could have been separate into a unified system.
