    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.
