電気外科手術は、ＲＦ電気外科発生器（電気手術器またはＥＳＵとしても知られる）、および生体組織を切断または凝固させるために様々な電圧で高周波交流無線周波（ＲＦ）電流の投入をもたらす電極を備えたハンドピースを使用する。ハンドピースは、１つの電極を有する単極の器具または２つの電極を有する双極の器具であり得る。単極の器具を使用する場合、リターン電極板が患者に取り付けられ、高周波電流が発生器から単極の器具へ、患者を経て患者のリターン電極板へ流れて、発生器へ戻るように流れる。単極電気外科手術は、その汎用性と有効性のために、一般的に用いられている。しかし、単極電気外科手術で発生する過剰な熱は、患者の背後に位置するリターン電極が高電圧および高ＲＦエネルギーを患者に通すため、過剰な組織の損傷および組織の壊死を引き起こす可能性がある。   Electrosurgery involves RF electrosurgical generators (also known as electrosurgical instruments or ESUs) and electrodes that provide for the application of high frequency alternating current radio frequency (RF) currents at various voltages to cut or coagulate biological tissue. Use the handpiece provided. The handpiece can be a monopolar instrument with one electrode or a bipolar instrument with two electrodes. When using a monopolar instrument, a return electrode plate is attached to the patient and high frequency current flows from the generator to the monopolar instrument, through the patient to the patient return electrode plate, and back to the generator. Monopolar electrosurgery is commonly used because of its versatility and effectiveness. However, the excessive heat generated in monopolar electrosurgery can cause excessive tissue damage and tissue necrosis because the return electrode located behind the patient passes high voltage and high RF energy through the patient. is there.

双極電気外科手術では、アクティブ電極およびリターン電極の両方が双極の器具に含まれているため、アクティブ出力機能と患者リターン機能の両方が手術部位で発生する。したがって、電流の経路は、アクティブ電極およびリターン電極との間に位置する生体組織に限定される。双極電気外科手術で、より低い電圧およびより少ないエネルギーを使用できるようになり、それによって単極電気外科手術に関連する組織損傷およびスパークの可能性が低減し、または排除されるが、大きな出血領域を切断および凝固する能力は限られている。   In bipolar electrosurgery, since both the active and return electrodes are included in the bipolar instrument, both the active output function and the patient return function occur at the surgical site. Therefore, the current path is limited to the living tissue located between the active electrode and the return electrode. Bipolar electrosurgery allows the use of lower voltages and less energy, thereby reducing or eliminating the potential for tissue damage and spark associated with monopolar electrosurgery, but with a large bleeding area The ability to cut and solidify is limited.

したがって、組織の損傷を伴わずに広い範囲の組織を切断および凝固することを可能にし、患者を経てエネルギーが通ることを排除する電気外科用ブレードに対し、必要性が存在している。鋭利な切断縁部と、電気外科用ブレードの対向する側部に配置されたアクティブ電極およびリターン電極の両方とを有する超極性電気外科用ブレードは、この必要性を満たすであろう。鋭利な切断縁部と、本発明を参照して説明した電気外科用ブレードの対向する両方の側部に配置されたアクティブ電極およびリターン電極とを有する超極性電気外科用ブレードは、煙排出能力を有さない電気外科用ハンドピース／ペンシルと共に使用することができるが、それらはまた、電気外科手術中に煙を排出することができる電気外科用ペンシル／ハンドピースと一緒に使用することも意図している。   Accordingly, a need exists for an electrosurgical blade that allows a wide range of tissue to be cut and coagulated without tissue damage and that eliminates the passage of energy through the patient. A superpolar electrosurgical blade having a sharp cutting edge and both active and return electrodes disposed on opposite sides of the electrosurgical blade would meet this need. A superpolar electrosurgical blade having a sharp cutting edge and active and return electrodes disposed on opposite sides of the electrosurgical blade described with reference to the present invention provides smoke evacuation capability. Although they can be used with electrosurgical handpieces / pencils that do not have them, they are also intended for use with electrosurgical pencil / handpieces that can evacuate smoke during electrosurgery. ing.

鋭利な切断縁部と、電気外科用ブレードの対向する側部に配置されたアクティブ電極およびリターン電極の両方とを備える電気外科用ブレードを有する超極性伸縮電気外科用ハンドピース／ペンシルはまた、広い範囲の生体組織の正確な切断および凝固の両方を可能にする。さらに、そのような超極性伸縮電気外科用ハンドピース／ペンシルは、ハンドピース／ペンシルの伸縮部材ならびにハンドピース／ペンシルの伸縮性部材内に配置された超極性電気外科用ブレードを延ばすことによって、使用者または外科医が、向上した視覚化の能力により、さらに容易かつ効率的に手術部位にアクセスすることを可能にする。本発明の超極性伸縮電気外科用ハンドピース／ペンシルはまた、手術部位での正確な切断、ならびに手術部位に位置する大きな生体組織領域の切断および凝固を実行することができる一方で、使用者または外科医が手術部位から煙および／またはデブリを排出することを可能にする。   A superpolar telescopic electrosurgical handpiece / pencil having an electrosurgical blade with a sharp cutting edge and both active and return electrodes disposed on opposite sides of the electrosurgical blade is also wide Allows both precise cutting and coagulation of a range of biological tissues. Further, such a superpolar telescopic electrosurgical handpiece / pencil can be used by extending a handpiece / pencil telescopic member and a superpolar electrosurgical blade disposed within the handpiece / pencil telescopic member. Allows a person or surgeon to more easily and efficiently access the surgical site with improved visualization capabilities. The superpolar telescopic electrosurgical handpiece / pencil of the present invention can also perform accurate cutting at the surgical site, as well as cutting and coagulating large areas of biological tissue located at the surgical site, Allows the surgeon to evacuate smoke and / or debris from the surgical site.
