Abstract
An electro-mechanical surgical device, system and/or method may include a housing, at least two opposing jaw, and at least one electrical contact associated with at least one of the jaws. The electrical contact may include at least one of a bipolar electrical contact and an ultrasonic electrical contact. The electrical contact may be a row of electrodes located on one or all of the jaws. A sensor may also be associated with any tissue located between the jaws to sense and report the temperature of that tissue. A piercable ampulla containing fluid may also be placed on at least one of the jaws so that the fluid is releasable when the jaws are in closed position and the electrode(s) pass through the tissue into the piercable ampulla.
Claims26
An electro-mechanical surgical device, comprising:
- a first jaw;
- a second jaw opposing the first jaw, the first jaw and the second jaw configured to clamp tissue therebetween;
- a plurality of ultrasonic resonator pins arranged on at least one of the first jaw and the second jaw;
- and
- an ultrasonic transducer configured to supply ultrasonic energy to the plurality of ultrasonic resonator pins.
An electro-mechanical surgical system, comprising:
- a surgical instrument including:
- a first jaw,
- a second jaw opposing the first jaw, the first jaw and second jaw configured to clamp tissue therebetween, and
- a plurality of ultrasonic resonator pins arranged on at least one of the first jaw and the second jaw;
- an ultrasonic transducer configured to supply ultrasonic energy to the plurality of ultrasonic resonator pins;
- and
- an elongated shaft having a distal end configured to detachably couple with the surgical instrument.
An electro-mechanical surgical device, comprising:
- a first jaw;
- a second jaw opposing the first jaw, the first jaw and the second jaw configured to clamp tissue therebetween;
- a plurality of electrodes arranged on at least one of the first jaw and the second jaw, the plurality of electrodes including at least one first electrode and at least one second electrode adjacent to the first electrode;
- and
- an arrangement configured to supply electrical energy to the electrodes so that the first electrode has a polarity opposite a polarity of the second electrode.
A method for performing a procedure on a body, comprising the steps of:
- (a) relatively moving a first jaw and a second jaw to clamp tissue therebetween, the first jaw arranged opposite to the second jaw, a plurality of ultrasonic resonator pins arranged on at least one of the first jaw and the second jaw;
- and
- (b) supplying ultrasonic energy to the ultrasonic resonator pins after the moving step.
