Definitions
- the invention relates to a surgical vaporization electrode.
- Electric surgical resection tools are known from the prior art, in the use of which for resection high-frequency (HF) alternating current is passed through the body part to be treated in order to selectively remove or cut the corresponding tissue locally.
- HF high-frequency
- Such resection tools are used in particular to provide e.g. to remove adenomatous tissue by vaporization.
- an RF voltage is applied to an electrode, which is generated by means of suitable RF generators and connected via appropriate feeds to the working part of the electrode, wherein such electrodes can be operated bipolar or monopolar depending on the training.
- bipolar technology in contrast to the monopolar technique, the current only flows through a small part of the body.
- the localized current density at the bipolar electrode causes a rapid heating of the tissue surrounding the electrode head with consecutive vaporization of the tissue water or the rinsing fluid surrounding the tissue (irrigating solution, saline).
- a thin gas layer forms around the tip of the electrode, which can be ionized at a sufficiently high voltage (plasma ignition) to form a constant plasma.
- the energy of the plasma is transferred to the cells of the tissue to be resected and leads to its localized vaporization.
- plasma vaporization can a
- Tissue can be separated and removed more gently and effectively than with conventional ones Vaporisation (eg by means of monopolar vaporization or by laser evaporation), since the plasma vaporization only requires the contact between electrode and tissue to a minimum and does not require high temperatures ("cold vaporisation").
- Vaporisation eg by means of monopolar vaporization or by laser evaporation
- conventional electrodes operate with a quasi-bipolar technique with active (RF-biased) electrode and return electrode.
- the return electrode is significantly larger than the active electrode, so that the plasma ignites only at the active electrode.
- the fork tubes holding the electrode head serve as a return electrode while the current is conducted back to the generator via the feed dog.
- the transporter is an instrument supplement which serves for the controlled guided movement of the electrode.
- Other conventional bipolar electrodes have a return electrode insulated from the electrode shaft, from which the current is conducted back through the electrode. These electrodes also operate quasi-bipolar, since only one pole is designed as an active electrode applied with HF voltage.
- Another disadvantage of conventional vaporization electrodes is the size of the active surface (work surface). The larger the surface at which the plasma is ignited, the more heat is given off to the surrounding saline. In order to achieve higher vaporization rates, it is not just possible to increase the active area. A larger active area also leads to a worse ignition behavior.
- the present invention has the object to provide a device which does not have the disadvantages mentioned or at least to a lesser extent.
- the invention relates to a surgical vaporization electrode which has an electrode head with at least two electrically conductive working surfaces which are arranged in electrical isolation from one another.
- the work surfaces that correspond to the poles of the electrode for example, layered by means of etching, sputtering, build-up welding, Soldering, electrochemical coating or other coating technologies are applied to an electrically non-conductive body.
- the electrode head is composed of a plurality of respectively conductive, mutually insulated partial bodies, each partial body having one of the working surfaces.
- the work surfaces in particular, the already known from the prior art materials into consideration.
- each of the working surfaces has at least one substantially annular, circular-sector-shaped, elliptical-ring-shaped or elliptical-sector-shaped surface region in planar projection, and the surface regions in the planar projection are arranged concentrically or approximately concentrically with one another.
- it is to be regarded as approximately concentric if the circle center or ellipse intersection points of the rings or ring segments do not deviate from one another by more than 20%, preferably not more than 10%, of their respective circle or largest ellipse diameter.
- substantially annular sector-shaped or elipsenringsektorförmigen surface areas is usually negligible, as the respective outer ring sector defining the circle or Elipsensektor to the respective inner annular sector defining circle or Elipsensektor extending surface edge is arranged exactly.
- other, elongated, curved surface areas may be provided which at least partially surround each other, in particular crescent-shaped or involute curved surface areas.
- a surgical instrument which comprises a surgical vaporizing electrode according to the invention having an HF generator, the HF generator being designed and connected to the surgical vaporizing electrode so that the working surfaces can be separately activated and deactivated.
- Activatable and deactivatable means that it can be acted upon by high-frequency AC voltage or separated from the high-frequency AC voltage.
- each working surface has a separate electrical supply line, which is connected to a high-frequency AC voltage source via a switch or electronic switching module known per se from electrical engineering, such as a relay.
- each work surface can be connected via a corresponding supply line with its own on and off switchable high-frequency AC voltage source.
- the surgical instrument has an electronic control for activating and deactivating the work surfaces.
- an electronic control for activating and deactivating the work surfaces.
- suitable for this purpose from the prior art per se known electronic control devices, which are suitable to the work surfaces respectively associated electronic switching modules or the work surfaces each associated high-frequency alternating voltage sources to control.
- the surgical instrument further comprises movement detection means for detecting a relative movement of the electrode head to a reference system, wherein the electronic control is adapted to activate and / or deactivate at least one of the work surfaces in response to the relative movement of the electrode head.
- a reference system can serve, for example, the feed dog for this purpose.
- the relative movement of the electrode head to the feed dog can, for example, be detected indirectly as a relative movement of the electrode shaft to the feed dog.
- a large number of prior art sensors per se are suitable for detecting movements, for example capacitive, magnetic or optical sensors. It is particularly preferred to arrange the sensors in reusable parts, e.g. in the transporter and not in the electrodes, which are disposable instruments.
- the electronic control is designed to activate at least one working surface leading in the direction of movement of the electrode head and to deactivate at least one working surface trailing in the direction of movement of the electrode head.
- the surgical instrument has impedance measuring means, wherein the electronic control is designed to activate and / or deactivate at least one of the work surfaces as a function of impedance measurements.
- the electronic control is designed to activate and / or deactivate at least one of the work surfaces as a function of impedance measurements.
- the surgical instrument is configured such that for plasma ignition a predetermined working surface is activated in front of one or more of the remaining working surfaces.
- Figure 1 a shows an embodiment of the electrode head of a surgical vaporization electrode according to the invention in cross section.
- FIG. 1b shows the underside of the electrode head of the vaporisation electrode from FIG.
- FIG. 2 shows a cross-section similar to FIG. 1a of a further embodiment of the electrode head of a surgical vaporization electrode according to the invention, whose plan view resembles FIG. 1b.
- FIG. 3 shows a cross section similar to FIG. 1a and FIG. 2
- Exemplary embodiment of the electrode head of a surgical vaporization electrode according to the invention whose plan view Fig. Lb again resembles.
- FIG. 4a shows an embodiment of the electrode head of another surgical vaporisation electrode according to the invention in cross-section, furthermore the interconnection of the working surfaces with further components of a surgical instrument according to the invention.
- FIG. 4b shows the underside of the electrode head of the vaporisation electrode from FIG. 4a in plan view (from below), the sectional plane being indicated by the line AA '.
- FIG. 5 shows the underside of the electrode head of a further vaporization electrode according to the invention in plan view (from below).
- Fig. La shows an embodiment of the electrode head 1 of a surgical vaporization electrode according to the invention.
- the sectional plane A-A ' is indicated in the lower-side plan view in Fig. Lb as a dashed line.
- the electrode head 1 consists of three metallic electrode bodies 2, 3, 4 and a divided into three insulating rings 5a, 5b, 5c insulator body 5.
- the outer surface of each of the electrode body 2, 3, 4 forms a corresponding working surface 12, 13, 14.
- the electrical leads 22, 23, 24 pass through a common, outwardly insulating head support 6, but are isolated from each other. This can e.g. be realized by a multi-core cable.
- the insulating head holder 6 can perform mechanical and insulating functions. But there is also the possibility that such functions are taken over by separate elements. For example, a wire can provide mechanical stability and a PTFE tube can accomplish the insulation.
- the electrode head 1 can be manufactured by assembling the insulating and electrode rings 5a, 5b, 5c, 2, 3 and the third electrode body 4 closing the body like a cap.
- the electrode heads shown in Figures 2 and 3 are of similar construction as in Figure 1a and have substantially the same arrangement of the working surfaces 12, 13, 14, as shown in Fig. Lb. However, here is a continuous body as the insulator body 5 is provided.
- the variant shown in FIG. 2 can be produced, for example, by casting the electrode bodies 2, 3, 4 with a high-temperature-resistant plastic, by inserting electrode bodies 2, 3 divided into a ceramic base body (and placing the cap-like electrode body 4) or by casting the metallic electrode body 2, 3, 4 in a shape having the insulator body 5 as a core.
- the work surfaces 12, 13, 14 are electrochemically applied to the base body 5 by build-up welding or another coating method.
- FIG. 4 a shows an exemplary embodiment of the electrode head 1 of a further surgical vaporisation electrode according to the invention.
- the sectional plane AA ' is indicated in the lower-side plan view in Fig. Lb as a dashed line.
- the electrode head 1 consists of three metallic electrode bodies 2, 3, 4, which are inserted into the insulator body 5, which in turn is held by an outwardly insulating head holder 6.
- the respective electrical leads 22, 23, 24 of the electrode body 2, 3, 4 are guided to the control and switching device 9.
- the control and switching device 9, the supply lines 22, 23, 24 separately interconnect with the RF voltage source 8 or switch floating.
- the electrode shaft 7 is guided to a feed dog 10. Via the capacitive sensor device 11, the control and switching device 9 can detect the movement of the electrode shaft 7 and thus of the electrode head 1 relative to the feed dog 10.
- the work surfaces 12, 13, 14 formed by the electrode bodies 2, 3, 4 lie next to or behind each other in this exemplary embodiment.
- leading working surface 13 can be activated while the trailing work surface 12 can remain floating, so that there is no thermal energy introduced in free saline.
- the middle working surface 14 can either be switched to the respective leading working surface 13 (or 12 in the opposite direction of movement), or else remain potential-free.
- such an electrode can also be designed with only two work surfaces. Or the middle working surface 14 is different than shown considerably smaller than the other work surfaces 12, 13 executed and used for plasma ignition.
- the electrode head 1 shown in FIG. 5 in a bottom plan view has two working surfaces 12, 13 in the sense of a real bipolar electrode. These can be produced, for example, lithographically in complicated outlines. Shown are work surfaces 12, 13, which are structured as in a planar projection circular sector-shaped, concentrically arranged zones. In the center there is another, in plane projection circular disc shaped zone. In space, the illustrated side of the electrode head 1 is in turn hemispherical or curved according to another portion of a spherical surface. The plasma is ignited alternately at both poles 12, 13. If the individual concentric zones are close enough to each other, a continuous plasma layer nevertheless results.
