Summary:An electrosurgical instrument has a movable tissue cutting mechanism and a pair of opposing jaws shaped and configured to move between a closed position for clamping and sealing tissue clamped therebetween and an open position. A first jaw has an exposed tissue sealing surface having a primary sealing surface and least one protrusion extending from the primary sealing surface for concentrating a sealing current through the at least one protrusion. A second jaw has an exposed tissue sealing surface having a primary sealing surface and at least one recess in the primary sealing surface for concentrating a sealing current through the at least one recess. The protrusion and the recess oppose one another when the jaws are in the closed position. Each of the jaws has an elongated slot for receiving a portion of the cutting mechanism. A related method is also disclosed. 种电外科仪器具有可移动的组织切割机构和对相对的钳，该钳被定形并且被构造成在用于将组织夹持在两者之间并且封口的关闭位置和打开位置之间移动。第钳具有露出的组织封口表面，其具有初级封口表面和从初级封口表面延伸的至少个突起，该至少个突起用于集中穿过其的封口电流。第二钳具有露出的组织封口表面，其具有初级封
