摘要

Abstract TWO-STAGE SWITCH FOR CORDLESS HAND-HELD ULTRASONIC CAUTERY CUTTING DEVICE An ultrasonic, self-powered surgical device [1300] includes a handle [1408], a self-contained power supply [3302] associated with the handle [1408], and a control circuit [4608] disposed within the handle [4604] and/or the power supply [3302]. The control circuit [4608] is operable to carry out at least two operational conditions of the surgical device. A two-stage switch [4736] is electrically connected to the control circuit [4608] and effects the at least two operational conditions of the surgical device. A first stage of the switch [4736] effects a first of the at least two operational conditions and a second stage of the switch [4736] effects a second of the at least two operational conditions that is different from the first operational condition.
