Abstract

A surgical device is disclosed including a housing having an activation switch. The activation switch is adapted to couple to an electrosurgical energy source and includes a knob. The knob is slideable with respect to the housing and travels within a guide channel defined within the housing. The activation switch is selectively moveable in a first direction within the guide channel. Moving the activation switch in the first direction sets a desired electrosurgical energy level. The activation switch is also moveable is a second direction. Moving the activation switch is the second direction activates the electrosurgical energy source.

Claims

1-20. -20. (canceled)

21. A surgical forceps, comprising:

a housing having at least one handle attached thereto and a shaft having a pair of jaw members at a distal end thereof the at least one handle being movable to actuate the jaw members for grasping tissue;

an activation switch disposed on the housing, the activation switch adapted to couple to an electrosurgical energy source, the activation switch including a knob slidingly disposed within a guide channel defined within said housing; and

the activation switch being selectively moveable in a first direction within the guide channel to set a desired electrosurgical energy level and the activation switch being selectively moveable in a second direction to activate the electrosurgical energy source.

22. The surgical forceps according to claim 21, wherein the activation switch electromechanically cooperates with a sliding potentiometer to adjust energy levels.

23. The surgical forceps according to claim 21, wherein the activation switch electromechanically cooperates with a voltage divider network to adjust energy levels.

24. The surgical forceps according to claim 21, wherein said forceps includes two handles that are configured to operate in unison to activate the jaw members.

25. An open style surgical forceps, comprising:

a housing having at least one handle attached thereto and a shaft having a pair of jaw members at a distal end thereof, the at least one handle being movable to actuate the jaw members for grasping tissue;

an activation switch disposed on the housing, the activation switch adapted to couple to an electrosurgical energy source, the activation switch including a knob slidingly disposed within a guide channel defined within said housing; and

the activation switch being selectively moveable in a first direction within the guide channel to set a desired electrosurgical energy level and the activation switch being selectively moveable in a second direction to activate the electrosurgical energy source.

26. The surgical forceps according to claim 25, wherein the activation switch electromechanically cooperates with a sliding potentiometer to adjust energy levels.

27. The surgical forceps according to claim 25, wherein the activation switch electromechanically cooperates with a voltage divider network to adjust energy levels.

28. A method for using a surgical device to administer electrosurgical energy to a patient, comprising the steps of:

providing a surgical device, including;

a housing having at least one handle attached thereto and a shaft having a pair of jaw members at a distal end thereof, the at least one handle being movable to actuate the jaw members for grasping tissue;

an activation switch disposed on the housing, the activation switch adapted to couple to an electrosurgical energy source, the activation switch including a knob slidingly disposed within a guide channel defined within said housing, wherein the activation switch electromechanically cooperates with at least one of a sliding potentiometer and a voltage divider network to adjust energy levels; and

the activation switch being selectively moveable in a first direction within the guide channel to set a desired electrosurgical energy level and the activation switch being selectively moveable in a second direction to activate the electrosurgical energy source;

sliding the knob to set the intensity level of electrosurgical energy; and

depressing the knob to activate electrosurgical energy.

29. An electrosurgical system for performing electrosurgery on a patient, the electrosurgical system comprising:

an electrosurgical energy source that provides electrosurgical energy;

an active electrode that supplies electrosurgical energy to a patient;

an electrosurgical return electrode which returns electrosurgical energy to the electrosurgical energy source; and

a surgical device, including;

a housing having at least one handle attached thereto and a shaft having a pair of jaw members at a distal end thereof, the at least one handle being movable to actuate the jaw members for grasping tissue;

an activation switch disposed on the handle, the activation switch adapted to couple to the electrosurgical energy source, the activation switch including a knob slidingly disposed within a guide channel defined within said housing, wherein the activation switch electromechanically cooperates with at least one of a sliding potentiometer and a voltage divider network to adjust energy levels; and

the activation switch being selectively moveable in a first direction within the guide channel to set a desired electrosurgical energy level and the activation switch being selectively moveable in a second direction to activate the electrosurgical energy source.
