Feasibility study on the implementation of waterjet technology for surgical procedures in Makkah hospitals [EMBARGOED]

Abstract

Waterjet machining (WJM) is an advanced material removal process where the material is removed by a high-velocity stream of water, either with or without an abrasive mixture, depending on its specific application. Waterjet technology has advanced into the medical and health industries and is slowly becoming popular for various surgical procedures, faster healing times, less bleeding, and the prevention of thermomechanical damage. A waterjet is always sharp and clean. It is seen as an advantage to use this technology. Therefore, this research discusses the feasibility of implementing waterjet technology for surgical procedures in Makkah hospitals, focusing on the technological, economical, and practical aspects. Questionnaires were designed and distributed. And interview conducted with the supplier. The technical and financial feasibility of using the waterjet technology in hydrosurgery were evaluated based on the existing equipment being used at the hospitals. A structured routine for management, handling, and maintenance was developed through a structured framework. However, from the survey, problems such as instability in dissection were identified, particularly when water is continuously used under high pressure, and any uncontrollable factors affecting tissue damage. Modifications to the equipment were proposed to solve the instability problem. A technical feasibility evaluation shows that the Versajet II equipment fulfills all the specifications and requirements that are needed to make it function properly. The financial analysis over the past five years has shown that the total life cycle cost (LCC) is SR 198000, and the purchase price can be found to be equal to SR 39600, which is still lower than the initial capital cost of SR 70000, which indicates that the equipment is actually financially feasible to be implemented. A well-structured framework model was developed for an appropriate management and handling system as well as for the scheduled maintenance system for waterjet technology applications for hydrosurgery at Makkah hospitals. Modifications to the existing design using the Piezo Actuator-Driven Pulsed Waterjet System (ADPJ) are proposed since it is a novel device that releases a small amount of reliably pulsed water while undeniably allowing precise dissection control. The implementation of waterjet technology for hydrosurgery at Makkah hospitals is found to be practically, technically, and financially feasible.
