Patent ID: 8758342

Claim:
A cordless cautery and cutting surgical device, comprising: at least one modular battery having a selectively removable first connector part; and a surgical handle having: a first handle body portion having: a cordless radio-frequency-signal-generation assembly generating an output radio-frequency signal at an output couple; and a surgical electrocautery and cutting bipolar end effector electrically connected to the output couple and having jaws and a cutting blade between the jaws, the radio-frequency-signal-generation assembly operable to supply selectively the output radio-frequency signal to the end effector when powered by the battery; a second handle body portion: connected to the first handle body portion; defining therein an aseptically sealable battery-holding compartment selectively exposed to the environment and removably holding therein the battery; and having a selectively removable second connector part operable to removably hold the first connector part thereto; and at least one electrically controlled motor assembly: disposed in one of the first and second handle body portions; electrically connected to at least one of the battery and the radio-frequency-signal-generation assembly and operable to receive at least one of power and control signals powering and controlling the motor assembly; and physically coupled to the blade and operable to extend and retract the blade, the second connector part having conductors electrically connecting the battery to at least one of the radio-frequency-signal-generation assembly and the motor assembly when the battery is removably disposed in the compartment.
