Design Optimization and Tradeoff Analysis of an Actuated Continuum Probe for Pulmonary Nodule Localization and...

Area of Science:

• Medical imaging
• Surgical robotics
• Biomedical engineering

Background:

• Pulmonary nodules require surgical resection, often without intraoperative imaging, complicating margin assessment.
• Accurate margin delineation is crucial for effective wedge resection and improved patient outcomes.
• Current methods lack the precision needed for confident surgical removal of pulmonary nodules.

Purpose of the Study:

• To design and optimize an actuated continuum probe for pulmonary nodule localization and resection.
• To enhance intraoperative imaging and precise mapping of nodules during surgery.
• To improve margin delineation accuracy and surgical efficacy for pulmonary nodule removal.

Main Methods:

• Utilized multiple objective genetic algorithms (MOGAs) for design space exploration.
• Employed a design of experiments (DOE) study to quantify dimensional relationships and actuation effects.
• Developed a modified ultrasound imaging approach using multiple scattering (MS) and single scattering (SS).

Main Results:

• Detailed the design optimization and tradeoff analysis of the actuated continuum probe.
• Quantified the impact of key dimensional relationships on probe actuation.
• Demonstrated the potential for enhanced margin delineation using the novel ultrasound technique.

Conclusions:

• The actuated continuum probe offers a minimally invasive solution for intraoperative pulmonary nodule imaging.
• This technology has the potential to significantly improve margin delineation accuracy and patient outcomes in pulmonary nodule resection.
• Further development and clinical deployment of this device are warranted.
