Technical Field
The present invention relates generally to an ultra polar electrosurgical blade and an ultra polar electrosurgical pencil that use monopolar energy in a bipolar mode for cutting and coagulation. The super-polar electrosurgical blade and the super-polar electrosurgical pencil are capable of cutting through the sharp non-conductive cutting end of the super-polar electrosurgical blade and cutting or coagulating by activating the active and return electrodes contained on the electrosurgical blade simultaneously.
The blade of the present invention has a non-conductive planar member having first and second opposing planar sides, a cut end and an opposing non-cut end, a first active electrode and a first return electrode both located on the first opposing planar side on the non-conductive planar member, and a second active electrode and a second return electrode both located on the second opposing planar side on the non-conductive planar member. The super-polar electrosurgical pencil of the present invention includes a hand piece having a first end and a second end and a super-polar electrosurgical blade of the present invention located within the first end of the hand piece. The handpiece may also include a smoke evacuation passageway contained therein for evacuating smoke and/or debris from the surgical site.
The super-polar telescopic electrosurgical pencil/handpiece of the present invention includes a handpiece member having a first end and a second end, a hollow telescoping member having a first end and a second end concentrically positioned within the first end of the handpiece, an electrosurgical blade having an active contact and a return contact both located within the first end of the hollow telescoping member, a first hollow conductive tubular member in contact with the active contact or the return contact of the electrosurgical blade contained within the hollow telescoping member, a first solid cylindrical member in contact with either the active contact or the return contact of the electrosurgical blade not in contact with the first hollow conductive tubular member and contained within the hollow telescoping member, a second hollow conductive tubular member contained within the handpiece member such that at least a portion of the first solid cylindrical member is contained within at least a portion of the second hollow conductive tubular member, the second solid cylindrical member is contained within the handpiece member such that at least a portion of the second solid cylindrical member is contained within at least a portion of the first hollow conductive tubular member. The super-polar telescopic electrosurgical pencil/handpiece of the present invention is also capable of evacuating smoke and/or debris from the surgical site.
Background
Electrosurgery uses an RF electrosurgical generator (also known as an electrosurgical unit or ESU) and a handpiece with electrodes to provide a high frequency, alternating Radio Frequency (RF) current input at various voltages to cut or coagulate biological tissue. The handpiece may be a monopolar instrument having one electrode or a bipolar instrument having two electrodes. When using a monopolar instrument, a return electrode pad is attached to the patient and high frequency current flows from the generator to the monopolar instrument, through the patient to the patient's return electrode pad, and back to the generator. Monopolar electrosurgery is commonly used because of its versatility and effectiveness. However, excessive heat generated by monopolar electrosurgery can cause excessive tissue damage and tissue necrosis because the return electrode located on the back of the patient causes high voltage and high RF energy to pass through the patient.
In bipolar electrosurgery, both the active output and patient return functions occur at the surgical site because both the active and return electrodes are contained in a bipolar instrument. Thus, the path of the current is limited to the biological tissue located between the active electrode and the return electrode. While bipolar electrosurgery enables the use of lower voltages and less energy, thereby reducing or eliminating the possibility of tissue damage and sparking associated with monopolar electrosurgery, bipolar electrosurgery has limited ability to cut and coagulate areas of large bleeding.
Accordingly, there is a need for an electrosurgical blade that allows for the cutting and coagulation of large areas of tissue without damaging the tissue and eliminating the passage of energy through the patient. A super-polar electrosurgical blade having a sharp cutting edge and an active electrode and a return electrode both on opposite sides of the electrosurgical blade would meet this need. The monopolar electrosurgical blade with a sharp cutting edge and the active and return electrodes located on two opposite sides of the electrosurgical blade described with reference to the present invention may be used with electrosurgical handpieces/pens without smoke evacuation capability, but they are also intended for use with electrosurgical pens/handpieces capable of evacuating smoke during an electrosurgical procedure.
An electrosurgical blade with a sharp cutting edge and a telescopic super-electrode electrosurgical handpiece/pen with both an active electrode and a return electrode on opposite sides of the electrosurgical blade will also enable precise cutting and coagulation of large areas of biological tissue. Further, by extending the telescoping member of the handpiece/pen and the ultrode electrosurgical blade within the telescoping member of the handpiece/pen, such a ultrode telescoping electrosurgical handpiece/pen would enable the user or surgeon to more easily and efficiently access the surgical site with enhanced viewing capabilities. The super-polar telescopic electrosurgical handpiece/pencil of the present invention also enables a user or surgeon to evacuate smoke and/or debris from the surgical site while simultaneously being able to perform precise cuts at the surgical site as well as cut and coagulate large areas of biological tissue located at the surgical site.

Detailed Description
Exemplary embodiments of the super-electrode electrosurgical blade and the super-electrode electrosurgical pencil of the present invention enable a user or surgeon to cut with the sharp non-conductive tip of the electrosurgical blade and coagulate large areas of biological tissue with the electrosurgical blade by placing the electrosurgical blade on either of its two sides where both the active and return electrodes are located. The electrosurgical blades and electrosurgical pencil of the present invention may also cut with the active and return electrodes of the electrosurgical blade. Exemplary embodiments of the present invention of a superelectrode electrosurgical blade and a superelectrode electrosurgical pencil include an electrosurgical blade having a non-conductive planar member with opposing planar sides, a cut end and a non-cut end, a first active electrode and a first return electrode each located on one opposing planar side of the non-conductive planar member, and a second active electrode and a second return electrode each located on the other opposing planar side of the non-conductive planar member. The cutting end of the non-conductive planar member may form a sharp non-conductive cutting end for cutting biological tissue, while the active and return electrodes on each side of the non-conductive planar member may be used to perform coagulation and cutting biological tissue.
Figures 1 and 3 show opposite side views of an exemplary embodiment of a superelectrode electrosurgical blade 10 of the present invention, comprising a non-conducting planar member 12 having a first opposing planar side 14 (see figure 1) and a second opposing planar side 16 (see figure 2) with opposing elongated edges 18, a cut end 20 and an opposing non-cut end 22, a first active electrode 24 and a first return electrode 28 each located on the first opposing planar side 14 of the non-conducting planar member 12, wherein at least a portion of the first opposing planar side 14 is exposed proximate the non-conductive cut end 20 of the non-conductive planar member 12, and the monopolar electrosurgical blade 10 further includes a second active electrode 44 and a second return electrode 38 each located on a second opposing planar side 16 of the non-conductive planar member 12, wherein at least a portion of the second opposing planar side 16 is exposed proximate the non-conductive cut end 20 of the non-conductive planar member 12.
