Cordless power-assisted medical cauterization and cutting device

摘要

A cordless cautery and cutting surgical device includes a modular battery and a surgical handle operable to removably hold the battery thereto. The handle has a cordless radio-frequency-signal-generation assembly and a surgical bipolar end effector having jaws and a cutting blade therebetween. The signal-generation assembly selectively supplies radio-frequency signal to the end effector when powered for electrocautery of tissue between the jaws. The handle defines therein an aseptically sealable battery-holding compartment selectively exposed to the environment and removably holding therein the battery. A motor assembly is disposed in the handle 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 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.

1. 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; anda 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; andhaving a selectively removable second connector part operable to removably hold the first connector part thereto; andat 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; andphysically 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.
