RESUMEN
Objective:To construct the preoperative examination system about equipment and its matching annex of 3D laparoscope imaging system so as to ensure normal application of equipment.Methods: The root cause analysis(RCA) was applied to solve problems that existed in the use of 3D laparoscope imaging system and to formulate the corresponding solving strategies. The functions and principles of all components of 3D laparoscopic imaging system were reviewed comprehensively. And the fishbone diagram of the cause of default was drawn to formulate solving strategies and evaluate the improvement effect. The data of 40 operations before improved measurement was implemented were divided into control group, and those after improved measurement was implemented were divided into observation group. The difference of the two group was analyzed so as to evaluate the improved effect.Results:On the basis of summarized key points of equipment and matching annex of preoperative 3D laparoscope imaging system, the RCA was applied to find the reason that lead to adverse feedback of clinical practice. Through implemented the disinfection and sterilization method with lesser damage, 3D laparoscope and its annex, the total number of adverse feedback of patients has decreased 60％.Conclusion:The established management system for safe use of 3D laparoscope imaging system which covers preoperative, intraoperative and postoperative stages can reduce the surgical risk and clinical adverse feedbacks comes from the equipment failure and inappropriate operation. Moreover, it can provide reference for the safe use and management of 3D laparoscopic imaging system.
