Abstract

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.

Claims

1. An ultrasonic surgical assembly, comprising:

an ultrasonic waveguide;

a cordless ultrasonic-movement-generation assembly having;

a driving-wave generation circuit having a generator output;

a removable battery electrically coupled to the ultrasonic-movement-generation assembly; and

a surgical handle having;

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; and

a second handle body portion connected to the first handle body portion and having;

a waveguide attachment dock exposed to the environment and having a first couple operable to connect the waveguide thereto; and

an ultrasonic-movement-generation assembly dock 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.

2. the ultrasonic surgical assembly according to claim 1, wherein the driving-wave generation circuit comprises at least one of:

a control circuit;

a drive circuit; and

a matching circuit.

3. The ultrasonic surgical assembly according to claim 1, wherein:

the waveguide attachment dock is rotatably attached to the second handle body portion;

the first couple is operable to rotatably connect the ultrasonic waveguide to the second handle body portion;

the transducer is rotatable with respect to the driving-wave generation circuit;

the ultrasonic-movement-generation assembly dock is shaped to rotatably connect the ultrasonic waveguide in the attachment dock to the transducer through the second handle body portion; and

the waveguide attachment dock and the ultrasonic-movement-generation assembly dock are disposed to directly physically couple the waveguide and the transducer and cause a corresponding rotation of the transducer with respect to the handle when at least one of the waveguide and the attachment dock rotates.

4. The ultrasonic surgical assembly according to claim 1, further comprising conductive power leads in the compartment shaped to electrically connect the battery to the ultrasonic-movement-generation assembly at least when the battery is sealed in the compartment.

5.
