Definitions
- the invention relates to a monopolar electrosurgical instrument for the treatment of biological tissue by means of a plasma, with a tubular conduit for guiding a gas to the treatment site, the conduit being made of electrically insulating material and a distal opening for the exit of the gas in the direction of the tissue to be treated and having an electrode disposed in the region of the distal opening in the conduit, wherein the
- Electrode for igniting a discharge in the gas is connectable to an electrosurgical generator.
- the invention further relates to an electrosurgical system, comprising a
- electrosurgical generator a gas source and an electrosurgical instrument.
- the invention relates to a method for producing an electrosurgical instrument.
- Such instruments and systems have been known for some time. They are used in surgery, for example, to obliterate or coagulate larger superficial tissue areas, for example to quench diffuse bleeding.
- the gas used here is usually argon, this form of treatment is therefore also referred to as argon plasma coagulation (APC).
- APC argon plasma coagulation
- Electrosurgical instruments for the APC are also referred to as APC probes.
- APC The main areas of application for APC are gastroenterology and, increasingly, laparoscopic surgery. While only very thin APC probes can be used in gastroenterology, larger diameters can be used in laparoscopic surgery. A larger diameter of the pipe allows a higher gas flow and thus a better treatment effect.
- a gas flow is first initiated through the conduit, then a high frequency voltage is applied to the electrode to ignite a discharge in the gas.
- a high frequency voltage is applied to the electrode to ignite a discharge in the gas.
- the voltage is applied between the electrode and a large area neutral electrode located away from the site of treatment so that the discharge between the electrode and the tissue to be treated is ignited.
- a second electrode is placed in the instrument and the discharge is ignited between the two electrodes.
- the object of the invention is to provide a monopolar electrosurgical instrument and an electrosurgical system, which is improved in terms of the disadvantages described.
- tubular conduit for conducting a gas to the treatment site the conduit being made of electrically insulating material and having a distal opening for the exit of the gas in the direction of the tissue to be treated, and having an electrode arranged in the region of the distal opening in the conduit; Electrode for igniting a discharge in the gas with an electrosurgical generator is connected, which is further developed in that the inner surface of the conduit in the region of the distal opening has an increased electrical conductivity.
- the portion of the inner surface of the conduit in which the electrical conductivity is increased, during use of the instrument is not one of the poles of the
- Instruments expires in two steps.
- a corona discharge is first ignited in the region of the electrode, which is replaced after a short time by an arc discharge, which generates the therapeutically usable plasma.
- a sleeve-shaped insert is arranged in the line in the region of the opening, whose inner surface has the increased electrical conductivity.
- This insert can be a metal sleeve.
- this can result in an unwanted current path in the APC probe, in which a sparkover from the probe to the metal sleeve and then from the metal sleeve to the tissue to be treated takes place. Therefore, the use is preferably also made of non-conductive material.
- the inner surface of the conduit or insert in the region of the distal opening has a conductivity which is increased by thermal or electrochemical treatment.
- a conductivity which is increased by thermal or electrochemical treatment.
- hydrocarbon or fluorocarbon materials e.g., polyethylene PE, polypropylene PP,
- Polytetrafluoroethylene PTFE are carbonized by heating or by electrical discharges, the polymers are broken at the surface and it forms a conductive carbon layer.
- the inner surface of the conduit or insert in the region of the distal opening is coated with a conductive substance.
- a conductive lacquer This can be done, for example, by applying a conductive lacquer, steaming with a metal, or by rubbing on a soft graphite rod. It has been shown here that the coating does not have to be durable. Rather, it is sufficient if the coating is present at the time of the first ignition of the APC probe. Surprisingly, it has been shown that subsequent ignition processes are possible quickly and safely, even after ignition has taken place, independently of a permanent coating.
- a conductive substance is embedded in the material of the conduit or the insert in the region of the distal opening.
- the conductive substance in the form of fibers or filaments is embedded in the material of the conduit or insert.
- the conductive substance of the embodiments described above may be carbon, or the conductive substance may include carbon. Carbon is physiologically harmless and has good conductivity. Alternatively, the conductive substance may be or include a metal. Some metals are also physiologically harmless and also have good conductivity, eg gold, iron, titanium.
- an electrosurgical system comprising an electrosurgical generator, a gas source and an electrosurgical instrument according to the above statements.
- APC treatments can be carried out reliably and safely.
- Increasing the conductivity of an inner surface of the conduit in the region of the opening wherein the step of increasing the conductivity may take place before or after the step of positioning the electrode in the conduit, and wherein during the step of increasing the
- the electrode is not connected to a voltage source.
- Method is particularly easy to automate, since a complex two-way connection of the electrode with a voltage source is eliminated.

In laparoscopic or gastroenterological procedures, the neutral electrode 9 is attached to a thigh of the patient. The APC probe 4 is positioned near the portion 10.
- the electrosurgical generator 2 and the gas source 3 are activated so that a stream 12 of ionized gas is delivered towards the portion 10 of the fabric 11 where it is e.g. a superficial bleeding stops.
- the circuit required to produce the ionized gas extends from the electrosurgical generator 2 via the conduit 6 to the APC probe 4, from there through the gas flow 12 into the tissue 11, and then via the neutral electrode 9 and the conduit 8 back to the electrosurgical generator 2. Since it is AC, the current flows naturally also in the opposite direction.
- the neutral electrode 9 is designed with a large area, so that when passing the current between tissue 10 and neutral electrode 9 only low current densities occur and the fabric 11 is not damaged outside of the portion 10 to be treated.
- the neutral electrode 9 is omitted, instead the circuit is closed via two electrodes provided in the APC probe.

- the APC probe 4 comprises a

- FIG. 3 shows the distal end of a monopolar APC probe 104 whose distal opening 125 is aligned in the direction of the longitudinal axis of the APC probe 104.
- the APC probe 104 in turn comprises a tubular conduit 122, in which an electrode 126 by means of a holding element 127th is attached. Also shown is an electrical lead 128 for connecting the electrode 126 to an electrosurgical generator.
- a conductive coating 130 This may be an electrically conductive lacquer, also called conductive lacquer.
- This conductive ink preferably consists of a bonding matrix, for example synthetic resin, and a conductive powdery filler such as silver, copper, or graphite.
- the conductive coating 130 may alternatively include a binder-free coating, e.g. a graphite layer.
