TR TR TR DESCRIPTION A SURGICAL DEVICE USED IN SPINE DISCECTOMY SURGERY Technical Field The invention relates to a surgical device that allows tissue vaporization with plasma instead of tearing the tissue in the herniated area in spinal discectomy surgeries. Prior Art The disc material found between human spinal bones degenerates over time as a result of a series of biomechanical and biochemical changes. This degeneration event and its more advanced form, the herniation of the disc and its pressure on the relevant nerve, cause pain, sensory deficits, loss of strength and reflex changes in people. Conditions caused by intervertebral disc herniation are a common health problem and cause significant work loss. For spinal discectomy surgeries that allow the evacuation of disc material, open discectomy, microdiscectomy and/or endoscopic discectomy procedures are performed. In these procedures, the process of physically breaking the hernia with a knife and aspirating it; It is a process with low sensitivity and high control difficulties. It also causes one of the biggest problems, recurrence. For this reason, instead of tearing off the tissue in the herniated area in spinal discectomy surgeries, devices are needed that allow the entire tissue in the herniated area to be removed and cleaned in a way that eliminates the possibility of recurrence. In the Russian patent document numbered RU2654504, which is in the state of the art, a device that enables the evaporation of surgical and physiotherapeutic effects on biological tissue by direct exposure to plasma flow is mentioned. The device in the prior art; It includes a cathode assembly with channels for supplying a plasma generating gas to the electric arc transition zone, a tungsten electrode, an anode assembly with an arc combustion chamber, and a plasma jet formation channel. An electrically neutral plasma is formed by the ionization of argon flowing through the electric arc of the plasma probe. The plasma probe contains an electric arc power source connected to the anode and cathode assemblies. Anode mechanism; It consists of a housing, wings, heat absorbing elements in the form of a radiator and a washer. Cathode mechanism; It consists of a tungsten electrode and a high temperature insulator made in the form of a ceramic sheath. The plasma generating channel is located in the center of the anode node. Gas supply channels pass into gas expansion channels. Tangential holes are made in the gas expansion channels to allow the gas to pass into the plasma generator channel. The tungsten electrode is fixed coaxially to the plasma generating channel using a ceramic sheath. After turning on the air suction pump, which creates a flow of cooling air along the fins of the radiator and supplies plasma gas (argon or helium) to the gas supply channels, the oscillator pierces and ionizes the gas space between the tungsten and the gas. At the same time, the tungsten electrode and the working washer of the anode mechanism provide voltage from the electric arc power source. The plasma probe is then automatically put into operating mode with a plasma-generating gas flow rate. When necessary, the strength of the arc current and the plasma-forming gas flow are changed. Thus, tissue vaporization can be achieved with plasma flow. In the United States patent document numbered U86105581, which is in the state of the art, a device that provides tissue ablation in the treatment of herniated discs is mentioned. The device in question is bipolar electrocautery and the hernia is vaporized by means of ionizing substances. 9.121 Brief Description of the Invention The purpose of this invention is to realize a surgical device that allows tissue vaporization with plasma instead of tearing the tissue in the hernia area in spinal discectomy surgeries. Another purpose of this invention is to realize a device that allows the tissue to be vaporized with plasma during the tissue removal process from the herniated area, thus eliminating the possibility of recurrence due to the remaining tissue fragments. Another purpose of this invention is to realize a device that can minimize the damage that may occur in the surrounding tissues due to heat during the tissue vaporization process. Detailed Description of the Invention "A Surgical Device Used in Spinal Discectomy Surgeries" to achieve the purpose of this invention is shown in the attached figures; Among these figures: Figure 1. is a visual of when an individual is treated with the surgical device and device that is the subject of the invention. Figure 2. A view of the probe of the surgical device that is the subject of the invention. Figure 3. is a detailed view of the probe of the surgical device that is the subject of the invention. The parts in the figures are numbered one by one and the equivalents of these numbers are given below: 1. Surgical device 2. Probe 9.121 22. Gas flow hole 23. Electrode 24. Protective cylinder 3. Feeding unit 4. Control unit In spinal discectomy surgeries, instead of tearing the tissue in the hernia area The surgical device of the present invention, which provides tissue vaporization with plasma - at least one probe (2) containing electrodes (23) at the ends of which the plasma that provides tissue vaporization is generated, - at least one probe (2) connected to the probe (2) to provide the power and gas source required for plasma formation. It includes a feeding unit (3) and at least one control unit (4) that controls the plasma formation and gas flow required for the vaporization of the tissue. The probe (2) located in the surgical device (1) of the present invention has a solid cylindrical electrical insulating rod (21) and four gas flow holes (22) extending within the electrical insulating rod (21). In an embodiment of the invention, the electrical insulating rod (21) of the probe (2) is made of ceramic material and has a maximum diameter of 4 mm. Electrodes (23) pass through the gas flow holes (22) and some of these electrodes (23) extend outside the electrical insulating rod (21). In an embodiment of the invention, the electrodes (23) of the probe (2) extend beyond the electrical insulating rod (21) by a maximum of 1 mm. In an embodiment of the invention, the electrodes (23) of the probe (2) are made of tungsten material and are in the form of wires with a maximum diameter of 0.75 mm. In an embodiment of the invention, the distance between the electrodes (23) extending inside the 9.121 probe (2) is maximum 2 mm. Gas flow is made through the other two holes of the electrical insulating rod (21) inside the probe (2), which do not pass through the electrode. In a preferred embodiment of the invention, argon, nitrogen and oxygen flow alone or as a mixture through the holes of the electrical insulating rod (21) in the probe (2) that do not pass through the electrode. Thanks to the arc formed by the high voltage given to the electrodes (23) in the probe (2) by the power source in the feeding unit (3), argon gas, flowing in the empty holes in the electrical insulating rod (21) and turning into point plasma form at the tip, flows out of the electrical insulating rod (21). By ensuring the vaporization of all the tissues remaining between the extending electrodes (23), it ensures that the hernia is destroyed and the possibility of recurrence is eliminated. Due to the cooling effect of the argon gas flowing through the electrical insulating rod (21), only the tissues between the electrodes (23) evaporate at the point where the tissue is contacted, and no damage occurs to the surrounding tissues that do not fall between the electrodes (23). Additionally, a cylindrical structure (24) surrounding the electrical insulating bar (21) and protecting it around the electrical insulating bar (21) is created from the outer part of the electrical insulating bar (21) of the probe (2) with four gas flow holes (22) without contacting the electrical insulating bar (21). ) is available. In summary, the electrical insulating rod (21) electrically isolates the electrodes (23) and directs the argon gas between the electrodes (23) thanks to the gas flow hole (23). In one embodiment of the invention, the protective cylindrical structure (24) in question is made of stainless steel material and has a maximum diameter of 6 mm. There is a trigger on the probe (2) that allows the surgeon to adjust the plasma formation rate and power amount. In this way, the surgeon can perform vaporization by working slowly at the critical points of the herniated area he wants to remove, and quickly in comfortable areas away from the critical points. The supply unit (3) located in the surgical device (1) of the invention provides the voltage source to the gas flow holes (22) in the probe (2), the gas source used in plasma formation, and the electrodes (23). In a 9.121 embodiment of the invention, the gas source provided by the feeding unit (3) is at least one of argon, oxygen, nitrogen or mixtures thereof. The feeding unit (3) is configured to be connected to the probe (2). The control unit (4) located in the surgical device (1) of the present invention consists of a pedal-trigger circuit that provides control of plasma formation and gas flow and the power supplies that feed it, a high voltage circuit that provides plasma formation and the power supplies of this circuit, which controls gas passage and gas flow. It contains a solenoid valve that provides control, an LCD screen that provides information about the valve, circuit and power supplies, two different trimpots that allow adjustment of the pulse frequency of the high voltage circuit, and a needle valve that allows precise flow adjustment of the gas outlet. The control unit (4) is configured to be connected to the supply unit (3). Since the surgical device (l) of the invention does not leave any residue after vaporizing the herniated tissue and destroying it with vacuum tools in spinal discectomy surgeries, the possibility of hernia recurrence is eliminated. During evaporation, after the electrodes (23) extending out from the electrical insulating rod (21) of the probe (2) come into contact with the tissue, it evaporates the tissue with the plasma formed between the electrodes (23). It does not require a shield or cooling devices. With the device (1) in question, the purpose of vaporizing the herniated tissue in an extremely difficult, sensitive and small area for discectomy purposes is achieved without damaging any nearby tissue. The device (l) of the invention also does not require special control circuits and current limitation circuits to reduce the uncontrolled spraying of saline solution and the damage it will cause to the surrounding tissues. 9.121 Around these basic concepts, it is possible to develop a wide variety of applications for a surgical device (1) used in spinal discectomy surgeries, which is the subject of the invention, and the invention cannot be limited to the examples explained here, it is essentially as stated in the claims.
