Definitions

• TITLE ARGON BEAM ASSISTED ELECTROSURGERY PENCIL WITH SMOKE EVACUATION
• the present invention generally relates to an argon beam assisted electrosurgery pencil/handpiece with smoke evacuation that includes the use of argon plasma coagulation in combination with electrosurgery in addition to smoke evacuation. More particularly, the surgical handpiece of the present invention includes functional elements that enable a surgeon/user to perform both cutting via an electrode and argon beam coagulation via the application of an argon beam, in combination with one another, and further, both of theses in combination with smoke evacuation.
• argon beam coagulation (ABC) current is applied to tissue by a directed beam of ionized argon gas which causes a uniform and shallow coagulation surface thereby stopping blood loss.
• Electrosurgery uses a power supply and handpiece with one or more electrodes to provide high frequency, alternating current input at various voltages (200- 10,000V) depending on the function, namely coagulation vs. cutting.
• voltage is usually lower than in cut mode and the slower heating process results in less heat. As a result, no vapor pocket is formed so the tissue for the most part remains intact but with cells and vessels destroyed and sealed at the point of contact.
• a surgical device or tool that enables a surgeon or user to utilize the best methods used for cutting and cessation of bleeding at the surgical site at the same time, or simultaneously, while also being able to evacuate smoke and debris away form the surgical site.
• Such a surgical device or tool would enable the surgeon or user to increase both the efficiency and accuracy of the surgery by enabling the surgeon or user to perform both tissue cutting and coagulation at the same time without switching between modes or methods thereby decreasing operating time.
• performing both tissue cutting and coagulation at the same time along with smoke evacuation would enable the surgeon or user to more clearly view the surgical site to ensure accuracy during the procedure without the need to stop and switch modes in order to stop bleeding at the surgery site before being able to clearly see the surgical site.
• the electrode can be positioned such that the coagulating material flows along all sides of, or completely around, the electrode during simultaneous cutting and coagulation.
• the hollow tubular member may be comprised of a metal and the coagulating material may be argon gas where a direct beam of ionized argon gas is applied to the surgical site during coagulation.
• the simultaneous cutting with the electrode and coagulation with ionized argon gas may also be simultaneously carried out while performing smoke evacuation with the vacuum.
• the end of the hollow tubular member and the end of the electrode connected to the hollow tubular member may preferably extend at least 3 cm beyond the end of the handpiece to ensure that coagulating material, such as argon gas for example, coming out of the hollow tubular member for coagulating is not immediately drawn back into the handpiece while smoke evacuation is taking place.
• the surgical pencil of the present invention includes a handpiece having a conduit and at least one electrical contact element, a hollow tubular member comprised of a conducting material that is concentrically contained within the conduit such that there is a space between the inner circumference of the handpiece and the outer circumference of the hollow tubular member and at least one electrical contact element in contact with the hollow tubular member, an electrode connected to the hollow tubular member, means for connecting an energy source to the electrical contact element, means for providing a coagulating material supply to the hollow tubular member, and means for supplying a vacuum to the space between the handpiece and the hollow tubular member.
• the hollow tubular member may be comprised of a metal and the coagulating material may be argon gas where a direct beam of ionized argon gas is applied to the surgical site during coagulation.
• the surgical pencil having the hollow tubular member comprised of a conducting material may include means for simultaneously effectuating cutting with the electrode and coagulation with the coagulating material and the electrode may be positioned so that the coagulating material flows along all sides, or completely around, the electrode during simultaneous cutting and coagulation.
• the surgical pencil having the hollow tubular member comprised of a conducting material may also include means for simultaneously effectuating the following: cutting with the electrode, coagulating with the coagulating material, and evacuating smoke and/or debris with the vacuum.
• the end of the hollow tubular member and the end of the electrode connected to the hollow tubular member may preferably extend at least 3 cm beyond the end of the handpiece to ensure that argon gas coming out of the hollow tubular member for coagulating is not immediately drawn back into the handpiece while smoke evacuation is taking place.
• the surgical pencil having the telescopic member and the hollow tubular member comprised of a conducting material may include means for simultaneously effectuating cutting with the electrode and coagulation with the coagulating material and the electrode may be positioned so that the coagulating material flows along all sides, or completely around, the electrode during simultaneous cutting and coagulation.
