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.

Battery powered surgical instrument

A medical instrument is disclosed. The medical instrument includes a housing and a handle for gripping by a user, an end effector coupled to the handle and having at least one electrical contact, a battery, and a radio frequency (RF) generation circuit coupled to and operated by the battery. The RF generation circuit is operable to generate an RF drive signal and to provide the RF drive signal to the at least one electrical contact, wherein the RF generation circuit is supported by the housing. The RF generation circuit includes a resonant circuit that includes at least one inductive element constructed of litz wire.

Litz wire battery powered device

A medical instrument is disclosed. The medical instrument includes at least one electrical contact, 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, a battery discharge circuit coupled to the RF generation circuit, a processor coupled to the battery discharge circuit, and a memory coupled to the processor. The memory stores computer instructions that when executed cause the processor to monitor battery capacity and send a signal to the battery discharge circuit to discharge a battery coupled to the battery discharge circuit when the battery capacity falls below a predetermined threshold.
