US 2014/0180175 A1 · HAND ACTIVATED ULTRASONIC INSTRUMENT

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, one or more 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 one or more buttons provide independent control of the power levels available from the generator, matching the two foot pedal configuration of the prior art.

Dependent claims

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 operatively coupled to the second end of the housing for causing rotation of the waveguide;
and
d) at least one switch located on the handle and electrically connected to the transducer assembly, wherein the transducer assembly is configured for accepting an electrical signal from the at least one switch and further communicating the electrical signal from the at least one switch to a generator for controlling the level of mechanical energy delivered by the transducer assembly.
