Abstract

An ultrasonic surgical clamp coagulator apparatus is configured to effect cutting, coagulation, and clamping of tissue by cooperation of a clamping mechanism of the apparatus with an associated ultrasonic end-effector. The handle of the apparatus is configured to permit hand activation for cutting, coagulation, and clamping of tissue during surgical procedures. In order to promote convenient and efficient use of the apparatus, the fingertip controls are provided directly into the disposal shears handle in a position that allows surgeons to activate the device without repositioning their hand. The two buttons provide independent control of the two power levels available from the generator, matching the two foot pedal configuration of the prior art.

Claims

9. An ultrasonic surgical instrument comprising:

a) a housing for accepting a transducer assembly for converting electrical energy to mechanical energy, the housing comprising;

b) an electronic circuit comprising at least one electronic component; and

c) at least one switch located on the housing and electrically connected to the transducer assembly by way of the electronic circuit for providing an electrical signal from the at least one switch to a generator for controlling the level of mechanical energy delivered by the transducer assembly.

10. The ultrasonic surgical instrument of claim 9, wherein the housing includes a handle configured for grasping by a user of the instrument.

11. The ultrasonic surgical instrument of claim 10, wherein the at least one switch is located on the handle.

12. The ultrasonic surgical instrument of claim 9, wherein the housing includes a first switch electrically connected to the transducer assembly for providing a first electrical signal from the first switch to the generator, and a second switch electrically connected to the transducer assembly for providing a second electrical signal from the second switch to the generator.

13. The ultrasonic instrument of claim 12, wherein the first and second switches are interlocked to prevent simultaneous activation of the first electrical signal and second electrical signal.

14. The ultrasonic surgical instrument of claim 11, wherein the handle includes a first switch electrically connected to the transducer assembly for providing a first electrical signal from the first switch to the generator, and a second switch electrically connected to the transducer for providing a second electrical signal from the second switch to the generator.

15. An ultrasonic surgical instrument comprising:

a) a housing having a handle configured to interface with a user of the instrument and a first end for accepting a transducer assembly for converting electrical energy to mechanical energy;

b) an ultrasonic waveguide positioned within and extending distally from a second end of the housing;

c) a rotation member for causing rotation of a working end of the instrument; and

d) at least one switch located on the housing and electrically connected to the transducer assembly for providing an electrical signal from the at least one switch to a generator for controlling the level of ultrasonic energy delivered by the transducer assembly.

1. An ultrasonic surgical instrument comprising:

a) a housing having a transducer assembly for converting electrical energy to mechanical energy;

b) an ultrasonic waveguide positioned within and extending distally from the housing;

c) a rotation member operatively coupled to the housing for causing rotation of the waveguide and transducer assembly;

d) an electronic circuit comprising at least one electronic component; and

e) at least one switch located on the housing and electrically connected to the transducer assembly by way of the electronic circuit for providing an electrical signal from the at least one switch to a generator for controlling the level of mechanical energy delivered by the transducer assembly.

2. The ultrasonic surgical instrument of claim 1, wherein the housing comprises two switches, the first switch electrically connected to the transducer assembly for providing a first electrical signal from the first switch to the generator, and the second switch electrically connected to the transducer assembly for providing a second electrical signal from the second switch to the generator.

3. The ultrasonic surgical instrument of claim 1, wherein the transducer assembly comprises an electrical contactor for accepting the electrical signal from the switch.

4. The ultrasonic instrument of claim 2, wherein the two switches are separated by a distance from about one-half inch to about one inch.

5. The ultrasonic instrument of claim 2, wherein the first and second switches each define a line of actuation that form an angle of actuation from about 10°

to about 30°

.

6. The ultrasonic instrument of claim 2, wherein the first and second switches are interlocked to prevent simultaneous activation of the first electrical signal and second electrical signal.

7. The ultrasonic instrument of claim 1, wherein the housing further comprises a handle configured for grasping by a user of the instrument.

8. The ultrasonic instrument of claim 7, wherein the first switch is located on the handle.

16. The ultrasonic surgical instrument of claim 15, wherein the at least one switch is located intermediate the handle and the rotation element.

17. The ultrasonic surgical instrument of claim 16, wherein the housing includes a first switch electrically connected to the handpiece for providing a first electrical signal to the generator, and a second switch electrically connected to the handpiece for providing a second electrical signal to the generator.

17-1. The ultrasonic surgical of claim 16, wherein the at least one switch is located on the handle.

19. The ultrasonic surgical instrument of claim 18, wherein the handle includes a first switch electrically connected to the handpiece for providing a first electrical signal to the generator, and a second switch electrically connected to the handpiece for providing a second electrical signal to the generator.
