Summary
This study developed a radio-frequency identification (RFID) integrated clip for precisely locating gastrointestinal lesions during minimally invasive surgery. The RFID clip demonstrated accuracy in vivo, improving lesion identification and resection margins.
Area of Science:
- Surgical Technology
- Biomedical Engineering
- Medical Devices
Background:
- Minimally invasive surgery (MIS) offers reduced patient recovery but faces challenges in precise lesion localization for gastrointestinal cancers.
- Accurate identification of internal lesions is difficult, potentially leading to excessive resection margins.
- Radio-frequency identification (RFID) systems are being explored to create reliable surgical markers.
Purpose of the Study:
- To develop and evaluate an RFID-integrated endoscopic clip for accurate gastrointestinal lesion localization in MIS.
- To assess the feasibility and efficacy of the RFID clip as a surgical marker.
Main Methods:
- Finite element method (FEM) analysis guided clip design and material selection (STS304, STS316).
- Ex-vivo experiments on porcine intestine evaluated clip stability.
- In-vivo studies on anesthetized porcine involved placing the RFID clip in the gastric wall and detecting it with a custom RFID detector.
Main Results:
- FEM analysis informed the fabrication of clips using STS304 and STS316 stainless steel.
- Ex-vivo tests confirmed clip stability.
- In-vivo detection of the RFID clip in porcine gastric walls was accurate, achieving a resection margin with low error.
Conclusions:
- The RFID-integrated clip shows feasibility and efficacy for marking gastrointestinal lesions in MIS.
- STS304 clips proved suitable, while STS316L was not recommended based on ex-vivo findings.
- Further research is needed to address clinical challenges like clip stability and RFID tag attachment for commercialization.
