摘要:
A method for assembling an ultrasonic surgical assembly includes the steps of substantially simultaneously removably coupling an ultrasonic-driving-wave-signal generating circuit to an ultrasonic surgical handle body and removably inserting an ultrasonic-movement-producing distal end of a rotatably free ultrasonic transducer into the ultrasonic surgical handle body. An ultrasonic waveguide is inserted into the ultrasonic surgical handle body opposite the ultrasonic-movement-producing distal end. The ultrasonic waveguide is rotated with respect to the ultrasonic transducer to fixedly couple the ultrasonic waveguide to the ultrasonic-movement-producing distal end of the ultrasonic transducer.

A method for powering electrically powered surgical instruments includes removably inserting a cordless battery assembly into a handle thereof, the instrument handles having a battery chamber and different types. The battery assembly comprises an energy cell powering a signal generation assembly of the instruments. A battery/handle interface has connectors mating with connectors within the chamber. A voltage-control circuit is operable to communicate with and power the signal generation assembly, detect which handle type is connected to the battery assembly, and provide different outputs in response to a detection of the handle types. As the battery assembly is inserted, connectors of the battery/handle interface are coupled with connectors within the battery chamber to communicatively couple the voltage-control circuit to the signal generation assembly and provide power thereto. The connected handle is detected and dependent upon the detected handle type a different one of the outputs are provided.

A method for encrypted authentication of interchangeable parts of a surgical instrument includes providing a surgical end effector at a distal end of a handle of the surgical instrument and electrically connecting an authentication controller within the handle to a receiving portion of the end effector. An interchangeable part is removably placed at the receiving portion. The interchangeable part is authenticated with the authentication controller when the interchangeable part is seated in the end effector.

An ultrasonic surgical assembly includes an ultrasonic waveguide and a cordless ultrasonic-movement-generation assembly that has a selectively removable securing connector and an output couple operable to impart ultrasonic movement to the ultrasonic waveguide when the waveguide is connected thereto. The assembly also includes a removable battery and a surgical handle that has a first handle body portion defining therein an aseptically sealable battery-holding compartment selectively exposed to the environment, aseptically removably holding therein the battery and electrically connecting the battery therein to the ultrasonic-movement-generation assembly. A second handle body portion is connected to the first handle body portion and has a waveguide attachment dock that is exposed to the environment and has a first couple operable to connect the waveguide thereto and an ultrasonic-movement-generation assembly dock that is exposed to the environment and shaped to removably secure the second handle body portion to the securing connector and connect the ultrasonic waveguide in the attachment dock to the output couple through the second handle body portion.
