Summary
This study introduces a novel robotic grid system for precise, parallel needle insertion in irreversible electroporation (IRE) tumor treatment. The robot ensures accuracy and needle alignment for improved therapeutic outcomes.
Area of Science:
- Robotics
- Medical Devices
- Oncology
Background:
- Accurate needle placement is critical for effective irreversible electroporation (IRE) tumor treatment.
- Maintaining needle parallelism ensures uniform electric field distribution for optimal therapeutic results.
Purpose of the Study:
- To present a novel robotic grid system designed for accurate, parallel multi-needle insertion.
- To enable precise targeting of lesions in various positions for IRE procedures.
Main Methods:
- A two-degree-of-freedom robotic system with an adjustable grid was developed.
- The robot's accuracy and needle parallelism were evaluated across different configurations and target depths.
Main Results:
- The robotic system demonstrated high precision, with an average positioning error of less than [math value].
- Needle orientation deviations were typically below [math value] across multiple insertions.
- The robot has dimensions of 134 mm x 46 mm and weighs 295 g.
Conclusions:
- The validated robotic grid system effectively maintains insertion accuracy and needle parallelism.
- The robot's performance indicates its suitability for enhancing irreversible electroporation procedures.
