Robotic-assisted endovascular surgery enables us to perform interventions from long distances. This study evaluates the workflow and telecommunication requirements of telerobotic peripheral vascular interventions.
Ten superficial femoral artery cases were performed by the operator being 44 miles away from the interventional suite, with an endovascular robotic system, on a high-fidelity endovascular simulator. Procedural success, technical success, fluoroscopy time, residual stenosis, contrast dose and network delay were registered. Communication success was assessed after each procedure on a scale from 1 (unacceptable) to 5 (ideal).
Procedural success and technical success were 100% and 80%, respectively. The mean residual stenosis, fluoroscopy time and contrast dose were 1.7 ± 5.25%, 6.5 ± 1.8 min and 58.8 ± 14.8 ml. The mean network latency was 38.9 ± 3.5 ms. Median communication success scores were 4.5 (min: 4, max: 5) reported by both the operator and the bedside technician on a scale of 1 (unacceptable) to 5 (ideal).
With a stable network connection and good communication protocol, a high success rate was achieved for remote robotic-assisted peripheral vascular intervention in an ex vivo model.
机器人辅助血管内手术使我们能够进行远距离的介入。本研究评估了远程机器人外周血管介入的工作流程和远程通信要求。
在高保真血管内模拟器上，操作员距离介入室 44 英里远，使用血管内机器人系统进行了 10 例股浅动脉病例。记录手术成功率、技术成功率、透视时间、残余狭窄、造影剂剂量和网络延迟。每次手术后，通过从 1（不可接受）到 5（理想）的评分评估沟通成功。
手术成功率和技术成功率分别为 100%和 80%。平均残余狭窄、透视时间和造影剂剂量分别为 1.7 ± 5.25%、6.5 ± 1.8 分钟和 58.8 ± 14.8 毫升。平均网络延迟为 38.9 ± 3.5 毫秒。操作员和床边技术人员在 1（不可接受）到 5（理想）的评分上，中位数沟通成功率得分为 4.5（最小：4，最大：5）。
在稳定的网络连接和良好的通信协议下，在离体模型中实现了远程机器人辅助外周血管介入的高成功率。
