Abstract: A medical instrument is disclosed. The medical instrument includes at least one electrical contact element, a battery, a radio frequency (RF) generation circuit coupled to and operated by the battery and operable to generate an RF drive signal and to provide the RF drive signal to the at least one electrical contact, and a battery discharge circuit coupled to the battery. A processor is coupled to the battery discharge circuit and a memory is coupled to the processor. The memory stores machine executable instructions that when executed cause the processor to monitor activation of the RF generation circuit and disable the RF generation circuit when the RF drive signal is fired a predetermined number of times. The medical instrument may include an activation switch and/or a disposal switch supported by the housing.
