摘要： An electrosurgical device comprises an end effector, a cutting member, and en electromechanical driver. The end effector comprises a pair of jaws that clamp tissue. The jaws include electrodes that deliver RF energy to clamped tissue. The cutting member cuts tissue clamped between the jaws. The electromechanical driver drives the cutting member. A control module commands the electromechanical driver, and regulates the delivery of RF energy to the electrodes, based on a combination of user input and feedback signals from the electrodes and from the electromechanical driver. The device may provide tactile feedback to the user through the user input feature, based on a load encountered by the cutting member. The device may alert the user when the exterior of end effector makes incidental contact with tissue, to avoid inadvertently burning the tissue. The device may include a removable battery pack to power the electromechanical driver and the electrodes.

The first portion comprises a first face at least partially surrounding the aperture, a staple cavity defined in the first face, a staple removably positioned within the staple cavity, and a first electrode positioned one of on and proximate to the first face. The second portion comprises a second face, an anvil pocket defined in the second face, and a second electrode positioned one of on and proximate to the second face, and a second electrode. The first electrode and the second electrode each comprise an arcuate portion. The first electrode has a different polarity than the second electrode.
摘要翻译： 外科缝合组件被构造成用于形成具有弓形部分的组织密封。 外科缝合组件包括从轴的远端延伸的端部执行器。 末端执行器包括第一部分和第二部分。 第一部分包括至少部分地围绕孔的第一面，限定在第一面中的缝合腔，可拆卸地定位在缝合腔内的缝合线，以及定位在第一面之上且靠近第一面的第一电极。 第二部分包括第二面，限定在第二面中的砧座，以及定位在第二面和其附近的第二电极和第二电极。 第一电极和第二电极各自包括弓形部分。 第一电极具有与第二电极不同的极性。
