    摘要： A thermal surgical instrument having a system to control the delivery of power from an energy source to active element located on a tip. The system for controlling delivery to the tip may include a control algorithm which uses on or more measurements, such as tip current, SWR, and rapid changes in reflected power, to manage power without affecting cutting efficacy, and in a manner that may be imperceptible by a surgeon. The system may utilize a state machine to determine the current environment in which the tip may be in. Power delivered to the tip may be selectively managed according to a fixed power index or a repeatedly executed power profile.

    摘要： A thermal surgical instrument comprising a conductor having a ferromagnetic material in electrical communication with the conductor, such that passage of electrical energy through the conductor causes substantially uniform heating of the ferromagnetic material sufficient to produce a desired therapeutic tissue effect is provided. The conductor may be shaped to facilitate resection of tissue from a patient and include a support to provide increase rigidity to the loop so that the conductor better resists bending during use. The ferromagnetic material quickly heats and cools in response to a controllable power delivery source. The thermal surgical instrument can be used for substantially simultaneously resecting tissue with hemostasis.
