3D Surgical Navigation for Accurate Tumor Resection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breast tumor resection surgeries often fail to completely remove cancerous tissue, leading to the need for additional surgeries and radiation treatment due to challenges in ensuring the entire tumor perimeter is excised, including filaments or fimbriae.
Innovation Solution
A surgical navigation system and method that generates surgical guidance cues based on three-dimensional spatial properties of the tumor, using patient-specific locator forms and imaging technologies to accurately guide the resection, accounting for tissue displacement and deformations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional wire or radio-opaque clip guidance is used for breast tumor resection, then the surgical procedure is simple to perform, but the accuracy of complete tumor removal is insufficient
Solution Approach 1:
The system performs preliminary actions by creating a 3D surface map of the breast tissue and determining surgical guidance cues (incision site, projection, margins) before the actual resection surgery. This pre-surgical planning and mapping enables more accurate tumor removal during the procedure.
Solution Approach 2:
The system creates a 3D surface map (a digital copy) of the actual breast tissue surface geometry. This digital copy is then used to generate surgical guidance cues that accurately represent the physical anatomy, enabling precise localization of the tumor and its margins without needing complex physical guidance devices.
2Reliability
If breast tumor resection is performed without comprehensive surgical guidance, then the surgical procedure is faster, but residual cancerous tissue remains requiring additional surgeries
Solution Approach 1:
The system provides feedback by generating surgical guidance cues (projection, margins, incision site) based on the 3D surface map that can be used intraoperatively to verify complete tumor removal. This feedback mechanism helps ensure all cancerous tissue including filaments and fimbriae are removed, reducing the need for reoperation.
Solution Approach 2:
The system transitions from traditional 2D imaging (mammography, ultrasound) to 3D surface mapping and visualization. This dimensional enhancement provides comprehensive spatial information about tumor location, depth, and margins, enabling more reliable complete removal in a single surgery.
3Measurement precision
If 3D surface mapping and surgical navigation system is implemented, then surgical guidance accuracy is improved, but the device and procedure complexity increases
Solution Approach 1:
The system replaces complex mechanical surgical guidance devices with a computational approach. Instead of using physical tracking devices, markers, or complex mechanical navigation equipment, the system uses 3D surface mapping and computer-generated surgical guidance cues that can be displayed on standard displays, simplifying the operational complexity.
Data Source
AI summary
A surgical navigation system includes a robotic delivery device, a processor communicatively coupled to the robotic delivery device, and a memory communicatively coupled to the processor. The memory stores (i) a surgical guidance cue indicating a three-dimensional spatial property associated with a tumor within a local tissue, and (ii) machine-readable instructions. When executed by the processor, the machine-readable instructions control the robotic delivery device, according to the surgical guidance cue, to deliver a therapeutic agent into an interior of the local tissue.
