摘要:
A self-powered surgical device, comprising a handle having a self-contained power supply and a control circuit operable to carry out at least two operational conditions of the surgical device; and a two-stage switch electrically connected to the control circuit, a first stage of the switch effecting a first of the at least two operational conditions and a second stage of the switch effecting a second of the at least two operational conditions that is different from the first operational condition, the two-stage switch having a variable resistance such that the first stage occurs when a first depression force is applied to the switch, the second stage occurs when a second depression force greater than the first depression force is applied to the switch, and a holding force lower than at least the second depression force is required to maintain the switch in the second stage.
