Augmented Reality (AR) can avoid some of the drawbacks of Minimally Invasive Surgery and may provide opportunities for developing innovative tools to assist surgeons. In laparoscopic surgery, the achievement of easy and sufficiently accurate registration is an open challenge. This is particularly true in procedures, such as laparoscopic abdominal Sacro-Colpopexy, where there is a lack of a sufficient number of visible anatomical landmarks to be used as a reference for registration. In an attempt to address the above limitations, we developed and preliminarily testes a constrained manual procedure based on the identification of a single anatomical landmark in the laparoscopic images, and the intraoperative measurement of the laparoscope orientation. Tests in a rigid in-vitro environment show good accuracy (median error 2.4 mm obtained in about 4 min) and good preliminary feedback from the technical staff who tested the system. Further experimentation in a more realistic environment is needed to validate these positive results. Clinical Relevance - This paper provides a new registration method for the development of AR educational videos and AR-based navigation systems for laparoscopic interventions.
增强现实（AR）可以避免微创手术的一些缺点，并为开发创新工具以协助外科医生提供机会。在腹腔镜手术中，实现轻松且足够准确的配准是一个开放性挑战。在腹腔镜下腹部 Sacro-Colpopexy 等手术中尤其如此，因为缺乏足够数量的可见解剖标志可作为配准的参考。为了克服上述限制，我们开发并初步测试了一种基于在腹腔镜图像中识别单个解剖标志和术中测量腹腔镜方向的受限手动程序。在刚性的体外环境中的测试表明具有良好的准确性（在大约 4 分钟内获得的中位数误差为 2.4 毫米），并且测试系统的技术人员提供了良好的初步反馈。需要在更现实的环境中进行进一步的实验来验证这些积极的结果。临床相关性-本文为开发用于腹腔镜干预的 AR 教育视频和基于 AR 的导航系统提供了一种新的注册方法。
