For many abdominal surgical interventions, laparotomy has gradually been replaced by laparoscopy, with numerous benefits for the patient in terms of post-operative recovery. However, during laparoscopy, the endoscope only provides a single viewpoint to the surgeon, leaving numerous blind spots and opening the way to peri-operative adverse events. Alternative camera systems have been proposed, but many lack the requisite resolution/robustness for use during surgery or cannot provide real-time images. Here, we present the added value of the Enhanced Laparoscopic Vision System (ELViS) which overcomes these limitations and provides a broad view of the surgical field in addition to the usual high-resolution endoscope.
Experienced laparoscopy surgeons performed several typical procedure steps on a live pig model. The time-to-completion for surgical exercises performed by conventional endoscopy and ELViS-assisted surgery was measured. A debriefing interview following each operating session was conducted by an ergonomist, and a System Usability Scale (SUS) score was determined.
Proof of concept of ELVIS was achieved in an animal model with seven expert surgeons without peroperative adverse events related to the surgical device. No differences were found in time-to-completion. Mean SUS score was 74.7, classifying the usability of the ELViS as "good". During the debriefing interview, surgeons highlighted several situations where the ELViS provided a real advantage (such as during instrument insertion, exploration of the abdominal cavity or for orientation during close work) and also suggested avenues for improvement of the system.
This first test of the ELViS prototype on a live animal model demonstrated its usability and provided promising and useful feedback for further development.
对于许多腹部外科手术干预，腹腔镜手术已逐渐取代开腹手术，患者术后恢复有许多好处。然而，在腹腔镜手术中，内窥镜仅为外科医生提供单一视角，留下许多盲点，并为围手术期不良事件开辟道路。已经提出了替代摄像系统，但许多系统缺乏手术所需的分辨率/稳健性，或者无法提供实时图像。在这里，我们介绍了增强腹腔镜视觉系统（ELViS）的附加值，该系统克服了这些限制，除了常规的高分辨率内窥镜外，还提供了手术区域的广阔视野。
经验丰富的腹腔镜外科医生在活体猪模型上进行了几个典型的手术步骤。使用常规内窥镜和 ELViS 辅助手术完成手术练习的时间进行了测量。每次手术结束后，由一名人体工程学家进行了一次汇报采访，并确定了系统可用性量表（SUS）评分。
ELViS 在七名专家外科医生的动物模型中证明了概念验证，没有与手术设备相关的围手术期不良事件。完成时间没有差异。平均 SUS 评分为 74.7，将 ELViS 的可用性归类为“良好”。在汇报采访中，外科医生强调了 ELViS 提供实际优势的几种情况（例如在器械插入、腹腔探查或在近距离工作时进行定位），并提出了改进系统的途径。
ELViS 原型在活体动物模型上的首次测试证明了其可用性，并为进一步开发提供了有希望和有用的反馈。
