Wound-Healing on Minimally Invasive Systems with Micro-Arc Oxidized (MAO) and Acid-Etched (SLA) Surface Modifications in Finite Element Liver Model

Abstract

The purpose of this research is to study micro-arc oxidation (MAO) and acid etching (SLA) in the liver after minimally invasive treatment. The three-dimensional (3D) liver model is rebuilt by magnetic resonance imaging (MRI) to simulate the clinical process. The processing layer is an important factor in clinical applications. Several studies have investigated the finite element model of the liver; however, few people have studied the equipment model with treated layers. The results revealed that temperature was significantly decreased when devices using MAO and SLA thin films. In addition, the SLA treatment group showed a relatively low temperature, which was 12.88% lower. It is an effective means to reduce abnormally thermal injury and lateral thermal area. The present study reveals that the novel nanostructured thin film on electrosurgery devices is an effective means of improving the performance of reducing over thermal injury and uniformly distributing temperature in livers.
