| Abstract: | Objective: Determination of the impact of a steerable Laparoscopic Aspirator-Irrigator (LAI) in sit- uations during robotic-assisted laparoscopic Hepato-Pancreato-Biliary (HPB) procedures where the Elefant is either inefficient in reaching or unable to reach the target area of aspiration. Background: Robotic-assisted laparoscopic surgery is a minimally invasive surgical technique used for a variety of procedures, including HPB procedures. The LAI is a frequently used instrument during these procedures. However, the conventional LAI has a limited range of movement. The steerable LAI aims to improve the freedom of movement. The goal of this research is to determine the potential im- pact of the steerable LAI in HPB procedures. Method: This study was conducted in three distinct phases. The first phase aimed to determine the sit- uations where the rigid LAI was inefficient in reaching or unable to reach the target area of aspiration and how frequent these situations occurred. The second phase consisted of the selection of a scenario where these factors frequently occurred and subsequently, the development of a simulation model and simulation protocol to accurately simulate the selected scenario. In the third and last phase, the perfor- mance of the steerable LAI was evaluated in comparison to the Elefant, a type of rigid LAI, using the simulation model and simulation protocol established in phase two. Additionally, a questionnaire was performed. Result: The steerable LAI outperformed the Elefant when it came to non-target tissue contact and the ability to reach the target area of aspiration. The Elefant outperformed the steerable LAI regarding the time it took to perform the aspirations. The questionnaire provided insight into the study cohort and the participants’ perceptions on the potential of the steerable LAI in clinical practice. Conclusion: This research shows that the steerable LAI has a positive impact on non-target tissue con- tact and the ability to reach the target area of aspiration. The next step in implementing the steerable LAI in clinical practice is to expand the research beyond the HPB specialisation. Keywords: Laparoscopy, Aspirator-irrigator, Steerable, Robot-assisted |
