CORDLESS POWER-ASSISTED MEDICAL CAUTERIZATION AND CUTTING DEVICE

摘要

Abstract CORDLESS POWER-ASSISTED MEDICAL CAUTERIZATION AND CUTTING A cordless cautery and cutting surgical device includes a modular battery and a surgical handle operable to removably hold the battery thereto. The handle [1800] has a cordless radio-frequency-signal-generation assembly and a surgical bipolar end effector [100] having jaws [120, 130] and a cutting blade [154] therebetween. The signal-generation assembly selectively supplies radio-frequency signal to the end effector [100] when powered for electrocautery of tissue between the jaws [120, 130]. The handle [1800] defines therein an aseptically salable battery-holding compartment selectively exposed to the environment and removably holding therein the battery. A motor assembly is disposed in the handle [1800] and is electrically connected to the battery and/or the signal-generation assembly and is powered and controlled thereby. The motor assembly physically couples to the blade [1350] and/or at least one jaw for moving the blade/jaw(s). The second connector part electrically connects the battery to the signal-generation assembly and/or the motor assembly when the battery is removably disposed in the compartment.
