    Methodology of Evaluating Pulling Performance of Laparoscopic Electrode Hook
    Author(s): Yuan Kang, Xiaoxin Wang, Lijun Zhu and Peng Zha*

    Purpose: Laparoscopic electrode hook is widely used in laparoscopic surgeries. However, the thermal damage determined by the power setting and the activation time is often concerning. The performance and safety of such electrodes are evaluated by the pulling force at a set power during dissection. The study is aimed to establish a method to evaluate hook performance and safety by combing ex vivo tests, simulation analysis, and validation in the acute animal experiment. Methods: In the ex vivo study, pulling force was tested by an Instron pulling force test system with set power, angle, and speed on porcine stomach tissue using CleanCoat™ L-Hook (Medtronic, Boulder, CO) and a novel design L-hook. A finite element model of the monopolar electrode was established to simulate the cutting efficiency and th.. View More»
