摘要： A trocar including a cannula with a tubular sleeve having a stepped region thereon is disclosed. The stepped region has a plurality of discrete steps. Each step has a step floor and a step support base tapering radially inwardly from the step floor to an adjacent step floor. When the trocar is inserted through the body wall, and the stepped region of the sleeve of the cannula contacts the body wall, the force required to inadvertently pull the cannula out of the body wall when surgical instruments are withdrawn from the cannula increases. Thus, the tubular sleeve of the cannula increases the retention force of the cannula during surgery. The retention force is increased without appreciably affecting the force required to insert the trocar through the body wall. Additionally, these benefits are achieved without using helical threads or externally mounted stability devices, which add cost, complexity and increased risk of causing unwanted tissue trauma.

摘要： An electrosurgical device includes a body, an end effector, a cutting member, and a shaft. The end effector comprises a pair of jaws and at least one electrode that is operable to deliver RF energy to tissue clamped between the jaws. The cutting member is operable to cut tissue clamped between the jaws. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. The body includes a controller operable to selectively actuate the articulation section. The controller may include a rotary knob, a pivoting knob, or a pivoting fin, among other things. An electrical coupling may contact a conductive moving member along at least two axes. A resiliently biased lever may assist a trigger in returning from an actuated position to a home position.

摘要： An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft extending between the body and the end effector. The end effector includes a pair of jaws and at least one electrode operable to deliver RF energy to tissue clamped between the jaws. The cutting member is operable to cut tissue clamped between the jaws. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. The articulation section may include beads, segments, asymmetric features, preformedly bent features, an integral hinge, a helical cutout or spring, clevis features, an angled joint, a beaded actuation linkage, and/or an offset pivot, among other things. The device may also include a crimped cutting member, a retroacting cutting member, dual pivoting jaws, and/or a wire tensioning assembly.
