摘要：
An electrosurgical device can have a housing and an electrode defining an energizable surface at least partially positioned externally of the housing. Such a device can have a first circuit and a second circuit. The housing can define a handpiece. The first circuit can be configured to selectively direct energy to a power element. The power element can be configured to selectively electrically couple to the electrode. The second circuit can have a selectively operable handpiece accessory. The handpiece can also have a device configured to direct suitable energy from the first circuit to the second circuit to power the second circuit. In some embodiments, the second circuit can be configured to selectively interrupt the first circuit. For example, the second circuit can interrupt the first circuit when a cumulative duration of operation of the second circuit exceeds an upper threshold duration. Methods of operating such handpieces are also disclosed.
