An inexpensive radiofrequency generator and power amplifier generates an electromagnetic wave which is transmitted from an incising transmitter probe. This electromagnetic wave is impedance matched, frequency matched, and power matched to initiate and sustain a harmonious plasma cloud with low atomic particle turbulence and chaos. This harmonious plasma cloud forms a coating over the surface of the incising tip as well as acts to reduce the energy output needed from the power amplifier.

METHOD OF PLASMA INCISION OF MATTER WITH A SPECIFICALLY TUNEDRADIOFREQUENCY ELECTROMAGNETIC FIELD GENERATOR

Background - Field of Invention 5 .)

This invention relates to incisions placed in matter with a harmonious plasma cloud, jspecifically to harmonious plasma clouds initiated and sustained by electromagnetic energy , waves transmitted from a radiofrequency signal generator System which is impédancematched, frequency matched and output power matched to the atomic particles comprising t 10 the harmonious plasma cloud that coats the activated transmitter incision probe.

Background - Description of Prior Art i

Most incisions made are created with a hardened physical blade, such as a steel blade, , 15 a sapphire blade, or a diamond blade. Such incisions are based on frictional physical i interactions of a Sharp, acute edge of hardened matter against a surface of the matter to beincised. Such purely physical methods of one hardened matter attempting to eut through .another hardened matter are inefficient and therefore expérience significant frictional irésistance and inefficiencies when the matter being incised is extremely solid and dense. For . 20 these reasons, others hâve resorted to methods such as electronically generated incisions, · electro-incisions or electrosurgery of matter. With this form of approach to incision of matter, ! !'

I l

J 2 011614 »1 electrical arcs induce arc bums or volatilization of matter while electrical ohmic résistance in jthe matter to be incised créâtes a heating effect due to phenomenon such as dielectrichystérésis and eddy currents. These last two phenomenon produce an effect known asdiathermy which may resuit in a physical reaction that can produce a cutting effect in matter.This approach has received limited use since its shortcomings include extensive damage tomatter outside of the intended incision path, with the résultant production of burning,charring and frequently unpleasant smelling fumes. The inefficiency of classic electro-incision units is manifested by the high power needed to produce a cutting effect at the ·incising tip, usually in excess of 50 watts of power. This relatively high power output neededin classic electrosurgical or electro-cutting units is secondary to the cutting inefficiency ofthese units which operate on a combination of classic ohmic diathermy and unstable, causticplasma arcing.

Lasers hâve also been used to incise and eut; however, these units are expensive andrequire a large amount of System input energy to create a laser beam with sufficient power toeut or make an incision into matter. Lasers hâve been used to generate plasma and are usedin processing such as etching in the field of microelectronics.

Plasma arcirig can be found in a number of areas such as welding arcs, spark plug ,arcs, lightening boit arcs, néon lights and electrosurgical arcs. Arcing, per se, is a form of |disharmonious plasma flow and represents uncontrolled, turbulent flow of ionized atomic ιparticles in plasma as well as increased atomic particle chaos in the plasma. The atomic ·? particle turbulence in plasma arcs represents a form of atomic particle chaos and the :uncontrolled nature of the atomic particle chaos causes a large quantity of energy spilloverinto matter outside of the intended path of incision and thereby may produce excessive (heating. This energy spillover into matter surrounding the intended path of incision into ίmatter results in energy exposure and damage to surrounding matter. Merely reducing thecutting tip power does not by itself significantly improve the plasma harmony in as much as itdoes not greatly decrease the flow turbulence of the ionized atomic particles that make up a *plasma arc. Moreover, our invention uses an array of physical chemistry principles tominimize disharmonious plasma arcing. Our invention minimizes disharmonious plasmaarcing by minimizing the atomic particle turbulence in the plasma cloud thereby greatlyreducing the plasma cloud atomic particle chaos and thereby creating a harmonious plasmacloud. Harmonious plasma cuts in a more controlled, efficient and safer manner because the 3 011 61 fl atomic particle components in a harmonious plasma cloud exist in a more stable, balanced, jand controlled State with a higher order of organization and less atomic particle turbulencethan disharmonious plasma. Our harmonious plasma cloud is furthermore compressed,controlled, contoured and shaped by utilizing the Pinch Effect of physics. Our compressedplasma cloud is then trapped and contained by the Magnetic Bottle phenomenon well known jto physicists and employed in fields such as nuclear physics.

Summary of the Invention 10 Our invention is a method of creating a harmonious plasma cloud with low turbulence : of atomic particles in the plasma cloud, thereby representing a state of low atomic particlechaos in the plasma. Physics defines four types of matter: solids, liquids, gases and plasma.Although examples of plasma are uncommon on earth, the majority of the universe iscomprised of plasma. Our form of plasma cloud is generated by an inexpensive 1 15 radiofrequency generator and amplifier similar to a standard, commercial radio transmitter.

The low input energy requirement of our electromagnetic generator system is partially made .possible by impédance matching, frequency matching, and system output power matching the j , î) incising transmitter probe to the harmonious plasma cloud. The activated transmitter incising jtip créâtes a plasma cloud which then forms a coating over the surface of the activated 20 transmitter incising tip. Our incising transmitter probe is preferably a solid, non-hollow -j conductor, but a hollow incising transmitter probe may also be used. When our!radiofrequency electromagnetic transmitter is activated, the majority of électron flow occursalong the surface or skin of the incising transmitter or cutting tip, according to the Skin Effect (of physics. By impédance matching the radiofrequency electromagnetic wave of the activated 25 incising transmitter tip to the plasma cloud coating the incising electrode tip, we produce a tightly coupled energy transfer system wherein a high percentage of total electromagneticenergy is transmitted into the plasma cloud whereas only a small percentage of the total·electromagnetic energy is reflected back into the activated transmitter incising probe. Thisconcept is analogous to impédance matching a standard radio transmitter antennae to 30 atmospheric air.

Arcing, per se, is a form of disharmonious plasma flow and represents uncontrolled, turbulent flow of ionized atomic particles in plasma that results in increased atomic particle j 4 011614 chaos in the plasma. Merely reducing the cutting tip power does not, however, significantly iimprove the plasma harmony in as much as it does not greatly decrease the flow turbulence ofthe ionized atomic particles that make up a plasma arc. The atomic particle turbulence inplasma arcs represents a form of atomic particle chaos and the uncontrolled nature of the , 5 atomic particle chaos causes a large quantity of energy spillover into matter outside of the !

intended path of incision and thereby may produce excessive heating. This energy spillover :into matter surrounding the intended path of incision into matter results in thermal exposureand radiation exposure with résultant damage to surrounding matter. Moreover, our inventionminimizes plasma arcing by minimizing the atomic particle turbulence in the plasma cloud J 10 thereby greatly reducing the plasma cloud atomic particle chaos and thereby creating a *harmonious plasma cloud.

Once the harmonious plasma cloud is created, the harmonious plasma cloud may thenbe compressed, controlled, contoured and shaped by utilizing the electromagnetic wavetransmitted from the active incising transmitter tip thereby employing the Pinch Effect of : 15 physics. This compressed plasma cloud is then trapped and contained by utilizing thetransmitted magnetic field according to the Magnetic Bottle phenomenon well known tophysicists and employed in fields such as Nuclear Physics. This allows us to decrease the ,thickness of the plasma coating covering the incising electrode by compressing, concentratingand trapping the harmonious plasma cloud. This effect thereby allows us to increase the 20 density of the harmonious plasma coating on the incising tip. Increased atomic particledensity of the harmonious plasma cloud produces an increased plasma cloud energy density. iThis therefore allows increased efficiency of incision into matter as well as a thinner path ofincision into the matter to be incised. Once our generated electromagnetic wave passesthrough the plasma coating, it then encounters the matter surrounding the harmonious plasma j i 25 cloud to which the electromagnetic wave is not well impédance matched. Therefore, a large percentage of total electromagnetic radiation energy is reflected back into the harmoniousplasma coating while only a small percentage of the total electromagnetic radiation is!transmitted into the surrounding matter. This physical interaction of electromagneticradiation with matter is described by the Tunnelling effect of physical chemistry. This 30 electromagnetic wave energy which is reflected back into the harmonious plasma cloud acts ; to fùrther energize the atomic particles of the plasma cloud and thereby fùrther decrease the ;electromagnetic energy output required by our electromagnetic waveform generator System. ' 1 t j ; t 5 011614 1 A combination of increased plasma harmony, increased harmonious plasma density, a jthinner coating of harmonious plasma on the activated transmitter incising probe, and theTunnelling Effect on our generated electromagnetic waveform results in a high efficiency,clean incision of matter in the intended path of incision with minimal spillover of energy into 5 matter surrounding the intended path of incision. Decreasing spillover of energy into tissue ; surrounding the intended path of incision results in a significant réduction of damage tomatter outside of the intended path of incision. According to principles of physics, 'harmonious plasma is formulated to eut and incise matter more efficiently and cleaner than prior modalities of incision. j 1 10 As opposed to classic electrocuting units, the oscillation frequency of our ! electromagnetic generator System is tuned to the molecular oscillation harmonies of theplasma cloud along the surface interface of the incising tip and matter to be incised. Thekinetic energy level of this thin layer of surface atomic partie les becomes extraordinarily highthereby forming a cloud of high energy ions and électrons surrounding the cutting electrode. i 15 The molécules in the plasma cloud are then attracted centripetally toward the cutting probe ‘ tip by a continuous or pulsed mode radiofrequency wave being fed into the cutting transmitter ;tip from which an electromagnetic wave is radiated. This effectively créâtes a highly .concentrated coating of harmonious cutting plasma over the surface of the cutting probe. Ourinvention allows us to create a cutting plasma cloud without injecting ionizable gas into the 20 field of cutting such as occurs in plasma generating devices such as plasma torches and ! etching Systems in plasma chambers. Once the electromagnetic radiation is tumed off, the !plasma rapidly discharges energy and the atomic particles in the plasma cloud lose the energyneeded to remain in the plasma State. By stimulating the electrode tip with radiofrequency jenergy while impédance matching, frequency matching, and power matching the activated· 25 electromagnetic probe to the harmonious plasma cloud coating, a plasma blade may be created which cuts with the energy of the plasma atomic particles. Impédance matching thetransmitted electromagnetic radiation to the plasma surrounding the incision tip is similar toiimpédance matching the electromagnetic radiation from a transmitter antennae into the airsurrounding the antennae. Once the electromagnetic wave passes through the layer of

I 30 plasma, it passes into matter not in the intended incision path and encounters matter to which it is not impédance matched causing a high order decay of the transmitted electromagnetic signal in a manner described by the physical chemistry principle of Tunnelling. For these ;

I

I î 6 011614! reasons, the efficiency of incision is amplified in the intended path of incision while it is jhighly damped outside of the intended path of incision, thereby producing minimalelectromagnetic radiation exposure, impact or side effects on the matter outside of the path ofintended incision. The end resuit is a safe, clean and efficient incision in matter. 5 .

Detailed Description of the Preferred Embodiments j

Our method of incising matter is different from ail prior methods of incising matter.

We employ an inexpensive electronic radiofrequency signal generator/amplifier system to 5 produce a pulsed or continuous radiofrequency electromagnetic wave which is directed into , an incisional handpiece and is then transmitted from an incising transmitter probe. Ourincising probe is preferably a solid, non-hollow conductor, although a partial or completely :hollow incising transmitter probe is acceptable. Our system is similar to a standard radiotransmitter which is impédance matched to atmospheric air, whereas our system is impédance 10 matched, frequency matched, power matched and tuned to a harmonious plasma cloudsurrounding the activated incising transmitter electrode tip.

Plasma is the least abundant of the four types of matter to be found on earth, althoughit is the most abundant form of matter to be found in the universe. Examples of plasma onearth include: arc welding, spark plug arcs, néon lights, arcs around lightning discharges, and 15 caustic plasma arcs seen in electrosurgery. Plasma is also used in fields such assemiconductor etching but is herein produced by expensive and high energy consumption i

Systems such as lasers or elaborate plasma etching chambers.

Our system employs an inexpensive, electronic radio frequency generator/amplifier J » system to produce and transmit a continuous or pulsed electromagnetic field from an20 activated incising transmitter probe. Individual parameters of this electromagnetic field generator system are largely determined by the atomic particle components along the 1interface of the transmitter incising probe and the matter to be incised. Our system utilizesthe atoms along the incising transmitting probe interface to generate a plasma cloud as ,opposed to Systems which require an ionizable gas to be injected into the field of incision and j 25 thereupon be eneTgized and converted into plasma. Our incising transmitter probe ispreferably linear or curvilinear in design; however, the shape of the transmitter tip electrodeis not necessarily spécifie in design and may even hâve a loop design. Our system is !impédance matched, frequency matched, and output power matched to generate and sustain aharmonious plasma cloud that coats the activated transmitter incising probe, thereby . 30 minimizing the classic plasma arcing occurring at the interface of the incising tip and the imatter to be incised. i 9 011614 t

Arcing, per se, is a form of disharmonious plasma flow and represents uncontrolled, iturbulent flow of ionized atomic particles in plasma that results in increased atomic particlechaos in the plasma. Merely reducing the cutting tip power does not by itself significantlyimprove the plasma harmony in as much as it does not greatly decrease the flow turbulence of 5 the ionized atomic particles that make up a plasma arc. As with other forms of matter, !plasma has a wide range of physical présentation including a wide range of température,density, flow characteristics, atomic particle components, etc.. On earth, plasma arcing can befound in a number of areas such as welding arcs, spark plug arcs, lightening boit arcs, néon !lights and electrosurgical arcs. The high atomic particle turbulence in plasma arcs represents j 10 a form of atomic particle chaos, wherein the uncontrolled nature of the atomic particle chaos !is caused by turbulent flow of the atomic particles in the plasma cloud. This form of plasmarepresents disharmonious plasma and results in excessive heating, or a large quantity ofenergy spillover into matter outside of the intended path of incision. This energy spilloverextending beyond the intended path of incision into matter results in energy exposure, 15 thermal exposure and damage to surrounding matter. In this way, our invention minimizesplasma arcing by minimizing the atomic particle turbulence and chaos in the plasma cloud, ! and thereby acts to generate a harmonious plasma cloud.

As the electromagnetic field traverses the thin coating of harmonious plasma j surrounding the activated transmitter incising probe, the electromagnetic field is slowly 20 damped or decreased in amplitude. Finally, the electromagnetic field will pass completely through the plasma cloud and will encounter matter outside of the intended incision path 'which surrounds the cloud of incising plasma. According to the physical chemistry principleof Tunnelling, the generated electromagnetic wave then encounters a barrier to which it is nottuned nor impédance matched and thereby a large percentage of the total energy of the ; 25 electromagnetic wave is reflected back into the harmonious plasma cloud. This reflectedelectromagnetic energy acts to farther energize the molecular particles in the plasma cloud,thereby reducing the output energy which must be transmitted by the electromagnetic wave ;eenerator system. This process also serves to minimize the percentage of totalelectromagnetic radiation that pénétrâtes into, that reacts with, and that présents potential 30 radiation exposure damage to matter outside of the intended incision path.

The centripetal force of our generated magnetic field is used to control the distance between the atomic particles in the harmonious plasma cloud and the surface of the activated 01 161 4 10 15 20 25 transmitter incising probe. To this end, the Pinch Effect which has been used for many years '>in fields such as plasma physics is employed in our System. In this way we are able tocompress, contour, shape and control the harmonious plasma cloud with a solid or hollowtransmitter incising probe. We then employ the Magnetic Bottle Effect used previously in ,

I fields such as nuclear physics to trap and contain the compressed plasma cloud without theneed of solid matter contaminent vessels and thereby avoiding the requirement to employhollow or cavity containing incising tip probes to trap and control plasma. Increasing thedensity of the atomic particles in the harmonious plasma cloud allows us to increase theplasma cloud power density thereby increasing the cutting efficiency and power of the jplasma cloud. !

Furthermore, compressing the plasma cloud causes a decrease in the cross sectionaldiameter of the plasma cloud thereby decreasing the width of the intended incision path aswell as minimizing side effects or potential adverse impact on matter outside of the intendedpath of incision. Once the electromagnetic. wave generator System has its power tumed off, ithe energy level of the harmonious plasma cloud quickly decays to a point where the atomicparticles comprising the plasma cloud çannot be sustained in the State of matter known asplasma.

Accordingly, the reader will see that employing a specifically tuned electromagnetic Jwave to generate a harmonious plasma which may hâve its shape and contour controlledallows us a more efficient, more controlled, less toxic, and more cost effective method ofincising matter.

Thus, the scope of the invention |should be determined by the appended claims and the legal équivalents, rather than theexamples given.
