AI Article Synopsis
- Surgeons often face challenges in identifying abnormal tissues and determining resection margins during minimally invasive surgeries.
- This study introduces a drop-in sensor probe that uses electrical bioimpedance technology, allowing surgeons to easily inspect suspicious tissue areas using laparoscopic forceps.
- Experiments conducted on porcine liver tissue demonstrate the probe's effectiveness, achieving tissue classification accuracies of 80% and 100% with impedance measurements taken across various frequencies.
Article Abstract
It is a common challenge for the surgeon to detect pathological tissues and determine the resection margin during a minimally invasive surgery. In this study, we present a drop-in sensor probe based on the electrical bioimpedance spectroscopic technology, which can be grasped by a laparoscopic forceps and controlled by the surgeon to inspect suspicious tissue area conveniently. The probe is designed with an optimized electrode and a suitable shape specifically for Minimally Invasive Surgery (MIS). Subsequently, a series of experiments are carried out with porcine liver tissue for feasibility validation. During the experiments, impedance measured at frequencies from 1 kHz to 2 MHz are collected on both normal tissues and water soaked tissue. In addition, classifiers based on discriminant analysis are developed. The result of the experiment indicate that the sensor probe can be used to measure the impedance of the tissue easily and the developed tissue classifier achieved accuracy of 80% and 100% respectively.
