摘要： A bipolar electrosurgical forceps includes first and second opposing jaw members having respective inwardly facing surfaces associated therewith. The first and second jaw members are adapted for relative movement between an open position to receive tissue and a closed position engaging tissue between the inwardly facing surfaces. The first and second jaw members each include a plurality of electrodes on the inwardly facing surfaces. The plurality of electrodes of the first jaw member are disposed in substantially vertical registration with the plurality of electrodes of the second jaw member. Each of the plurality of electrodes is configured to connect to a source of electrosurgical energy. Electrodes on at least one jaw member are grouped in pairs and each respective pair aligns with at least one electrode on the opposite jaw member. A multiplexer controls current density or activation sequence of the electrosurgical energy to each electrode.

摘要： A bipolar electrosurgical forceps includes first and second opposing jaw members having respective tissue engaging surfaces associated therewith. The first and second jaw members are adapted for relative movement between an open position to receive tissue and a closed position engaging tissue between the tissue engaging surfaces to effect a tissue seal upon activation of the forceps. The first and second jaw members each include an electrode having a plurality of tissue engaging surfaces which define at least one channel therebetween. The plurality of tissue engaging surfaces of the first jaw member are substantially aligned with the plurality of tissue engaging surfaces of the second jaw member so as to impede fluid flow therebetween and force tissue fluid to flow within the at least one channel during the sealing process.
摘要翻译：双极电外科钳包括第一和第二相对的钳口构件，其具有与其相关联的各自的组织接合表面。第一和第二钳口构件适于在接收组织的打开位置和接合组织接合表面之间的组织的关闭位置之间进行相对运动，以在激活钳子时实现组织密封。第一和第二钳口构件各自包括具有多个组织接合表面的电极，其在它们之间限定至少一个通道。第一钳口构件的多个组织接合表面基本上与第二钳口构件的多个组织接合表面对准，以便阻止其间的流体流动，并且在密封过程期间迫使组织流体在至少一个通道内流动。
