Abstract

An ultrasonic surgical waveguide driving assembly for attachment to a surgical ultrasonic instrument handle with a cordless power source therein includes a reusable cordless ultrasonic transducer that has an ultrasonic waveguide couple at which the transducer is operable to excite a waveguide attached thereto and a power input disposed to substantially simultaneously connect the waveguide couple to a waveguide and the power input to a power source located within the handle.

Claims

1. An ultrasonic surgical waveguide driving assembly to be attached to a surgical ultrasonic instrument handle having a cordless power source therein and a waveguide, the assembly comprising:

a removable shell housing a cordless ultrasonic transducer and having;

an outer surface with at least one electrically conductive contact;

an ultrasonic waveguide couple at which the transducer is operable to excite the waveguide attached thereto and produce movement at a portion of the waveguide sufficient to at least one of cut and cauterize human tissue; and

an ultrasonic handle couple operable to substantially simultaneously connect;

the transducer to the instrument handle; and

the at least one electrically conductive contact to the power source.

2. The assembly according to claim 1, wherein the ultrasonic handle couple is operable to also substantially simultaneously connect the waveguide couple to the waveguide.

3. The assembly according to claim 1, wherein the shell includes a distal end at which is disposed the waveguide couple, the handle couple, and the at least one electrically conductive contact.

4. The assembly according to claim 1, wherein the transducer includes a cord-free proximal end.

5. The assembly according to claim 1, wherein the at least one electrically conductive contact is a pair of ring-shaped contacts.

6. The assembly according to claim 5, wherein the ring-shaped contacts circumscribe the waveguide couple.

7. The assembly according to claim 1, wherein the power source is a battery.

8. The assembly according to claim 7, wherein the battery is rechargeable.

9. The assembly according to claim 1, wherein the substantially simultaneous connection places the transducer in communicative contact with the power source one of before and upon finalizing mechanical connection of the transducer and the waveguide.

10. An ultrasonic surgical waveguide driving assembly to be attached to a surgical ultrasonic instrument handle having a waveguide and a cordless power source therein, the assembly comprising:

a removable shell housing a cordless ultrasonic transducer and having;

an outer surface with at least one electrically conductive contact;

a cord-free transducer body cordlessly connectable to the at least one electrically conductive contact;

an ultrasonic waveguide couple at the transducer body and at which the transducer is operable to excite the waveguide attached thereto and produce movement at a portion of the waveguide sufficient to at least one of cut and cauterize human tissue; and

an ultrasonic instrument handle couple at the transducer body and operable to substantially simultaneously connect;

the transducer to the instrument handle; and

the at least one electrically conductive contact to the power source.
