    摘要： An articulate minimally invasive surgical instrument with a flexible wrist to facilitate the safe placement and provide visual verification of the ablation catheter or other devices in Cardiac Tissue Ablation (CTA) treatments is described. In one embodiment, the instrument is an endoscope which has an elongate shaft, a flexible wrist at the working end of the shaft, and a vision scope lens at the tip of the flexible wrist. The flexible wrist has at least one degree of freedom to provide the desired articulation. It is actuated and controlled by a drive mechanism located in the housing at the distal end of the shaft. The articulation of the endoscope allows images of hard-to-see places to be taken for use in assisting the placement of the ablation catheter on the desired cardiac tissue. The endoscope may further include couplings to releasably attach an ablation device/catheter or a catheter guide to the endoscope thereby further utilizing the endoscope articulation to facilitate placement of the ablation catheter on hard-to-reach cardiac tissues. In another embodiment, the articulate instrument is a grasper or any other instrument with a flexible wrist and a built-in lumen to allow an endoscope to insert and be guided to the distal end of the instrument.

    摘要翻译： 描述了一种具有柔性手腕的关节微创手术器械，以便于安全放置，并提供消融导管或心脏组织消融（CTA）治疗中的其他装置的视觉验证。 在一个实施例中，仪器是具有细长轴，在轴的工作端的柔性腕部和在柔性腕部的尖端处的视力范围透镜的内窥镜。 柔性手腕具有至少一个自由度以提供所需的铰接。 它由位于轴远端的壳体中的驱动机构致动和控制。 内窥镜的关节运动允许观看难看的位置的图像用于辅助将消融导管放置在期望的心脏组织上。 内窥镜还可以包括联接器以将消融装置/导管或导管引导件可释放地附接到内窥镜，从而进一步利用内窥镜关节以便于将消融导管放置在难以到达的心脏组织上。 在另一个实施例中，关节式器械是具有柔性手腕和内置内腔的抓紧器或任何其它器械，以允许内窥镜插入并被引导到器械的远端。

    摘要： The present invention is directed to an articulate minimally invasive surgical instrument with a flexible wrist to facilitate the safe placement and provide visual verification of the ablation catheter or other devices in Cardiac Tissue Ablation (CTA) treatments. In one embodiment, the instrument is an endoscope which has an elongate shaft, a flexible wrist at the working end of the shaft, and a vision scope lens at the tip of the flexible wrist. The flexible wrist has at least one degree of freedom to provide the desired articulation. It is actuated and controlled by a drive mechanism located in the housing at the distal end of the shaft. The articulation of the endoscope allows images of hard-to-see places to be taken for use in assisting the placement of the ablation catheter on the desired cardiac tissue. The endoscope may further include couplings to releasably attach an ablation device/catheter or a catheter guide to the endoscope thereby further utilizing the endoscope articulation to facilitate placement of the ablation catheter on hard-to-reach cardiac tissues.
