    摘要： A laparoscopic liver resection device is described. The device combines the Radiofrequency Ablation (RFA) technology with a cutting mechanism, a blood-flow sensor and a flexible actuation mechanism to simultaneously coagulate and cut the liver tissue and detect the presence of blood flow to confirm avascularity. The present invention eliminates the risk of excess bleeding due to cutting too deep and reduces recovery time and the time spent on re-coagulation of coagulated areas, thereby shortening duration of surgery. Also embodiments prevent excess ablation by stopping ablation activity on the target tissue as soon as insufficient or no blood flow in the target tissue is detected. Thus a closed loop control for a bloodless tissue/organ division method is provided.

    摘要翻译： 描述了腹腔镜肝切除装置。 该装置将射频消融（RFA）技术与切割机构，血流传感器和柔性致动机构结合，以同时凝结和切割肝组织并检测血流的存在以确认血流性。 本发明消除了由于切割过深而导致的过度出血的风险，并且减少了恢复时间和用于凝结区域再凝结的时间，从而缩短了手术的持续时间。 此外，一旦检测到目标组织中的血液不足或没有血液流动，则实施例也可以通过停止靶组织上的消融活性来防止过度消融。 因此，提供了无血液组织/器官分割方法的闭环控制。
