Abstract: A surgical forceps includes a housing having one or more shafts attached thereto and an end effector assembly disposed at a distal end thereof. The end effector assembly includes first and second jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable from an open position to a closed position for grasping tissue therebetween. The jaw members include at least one sensing component that determines an output of one or both of cross-sectional diameter and composition of tissue disposed between the jaw members. A processing component is configured to receive the output and determine a seal pressure for adequately sealing tissue disposed between the jaw members based upon the output. A regulating component regulates the movement of the jaw members between the first and second positions such that the determined seal pressure is applied to tissue disposed therebetween.

Abstract: An electrosurgical system includes an energy source adapted to supply energy to tissue. The energy source includes a microprocessor configured to execute a tissue treatment algorithm configured to control the supply of electrosurgical energy to tissue and process a configuration file including at least one parameter of the tissue treatment algorithm. The at least one parameter is adjustable to effect a tissue seal result. The microprocessor generates a target impedance trajectory based on at least one parameter of the tissue treatment algorithm and is further configured to drive tissue impedance along the target impedance trajectory by adjusting the supply of energy to tissue to substantially match tissue impedance to a corresponding target impedance value. The system also includes an electrosurgical instrument including at least one active electrode adapted to apply electrosurgical energy to tissue.

Abstract: A surgical forceps includes a housing having a shaft attached thereto and an end effector assembly disposed at a distal end of the shaft. The end effector assembly includes first and second jaw members having opposed seal plates, each of the seal plates having a width. At least one of the jaw members is moveable from an open position to a closed position for grasping tissue therebetween. A sensing component is configured to determine an output relating to a diameter of tissue or a composition of tissue disposed between the opposed seal plates of the first and second jaw members. An expanding component is configured to expand the width of at least one of the opposed seal plates according to the determined output.

Abstract: A forceps includes an end effector assembly including a pair of jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable relative to the other between a spaced apart position, a first approximated position, and a second approximated position. The jaw members are configured to apply a pre-determined pressure to tissue disposed therebetween in each of the first and second approximated positions. A sealing pressure is applied to tissue disposed between the jaw members when the jaw members are in the first approximated position. A cutting pressure is applied to tissue disposed between the jaw members when the jaw members are in the second approximated position.
Abstract translation: 镊子包括端部执行器组件，其包括相对于彼此相对设置的一对钳口构件。 至少一个钳口构件可相对于彼此在间隔开的位置，第一近似位置和第二近似位置之间移动。 钳口构件构造成对第一和第二近似位置中的每一个施加预定压力到设置在其间的组织。 当钳口构件处于第一近似位置时，密封压力施加到设置在钳口构件之间的组织。 当钳口构件处于第二近似位置时，切割压力施加到设置在钳口构件之间的组织。
