Abstract
Description
Technical Field
[0001] This utility model relates to the fields of low-temperature plasma acupuncture and radiofrequency thermocoagulation therapy, and in particular to a disposable conductive electrode. Background Technology
[0002] Low-temperature plasma and radiofrequency thermocoagulation are two commonly used treatments for pain, and they can complement each other in practical applications: Low-temperature plasma is mainly used to vaporize, cut, punch, ablate, shrink, peel, and stop bleeding of tissues, and can treat pain caused by tissue abnormalities; Radiofrequency thermocoagulation is mainly used for nerve and muscle tissues and can treat neuropathic pain.
[0003] The equipment used in low-temperature plasma therapy includes a low-temperature plasma energy platform and a low-temperature plasma needle (as a consumable). The needle tip is inserted into the tissue, forming a thin plasma layer between the electrode and the tissue, transferring energy to the tissue. The equipment used in radiofrequency thermocoagulation therapy includes a radiofrequency thermocoagulator platform and a radiofrequency cannula (as a consumable). This allows for the injection of fluid into the nerve, and the electrodes within the cannula are used to discharge electricity and treat the nerve. In the practice of using these combined, the following problems have arisen:
[0004] 1. Since the low-temperature plasma needle knife is solid, it is impossible to perform the necessary liquid injections before and after low-temperature plasma treatment. Therefore, in the current technology, a separate syringe is usually used to repeatedly puncture and locate the abnormal tissue, which increases the workload and poses medical risks.
[0005] 2. Current radiofrequency cannulas cannot be used on low-temperature plasma energy platforms. Furthermore, the electrodes of radiofrequency cannulas are sterilized and reused, resulting in low work efficiency (a machine is equipped with 4 electrodes, and theoretically, a maximum of 4-8 treatments can be performed per day). At the same time, the electrodes are relatively expensive and are precision parts; once damaged, they can only be replaced and cannot be repaired. Utility Model Content
[0006] The technical problem to be solved by this invention is to overcome the defects of consumables in existing low-temperature plasma therapy and radiofrequency thermocoagulation therapy, and to provide a disposable energy-conducting electrode.
[0007] The present invention solves the above-mentioned technical problems through the following technical solution:
[0008] A disposable energy-conducting electrode includes a plug end and a needle core, wherein the plug end is adaptable to a low-temperature plasma energy platform and a radio frequency thermocoagulator platform;
[0009] The total length of the needle core is greater than or equal to 45mm, the outer diameter of the needle core is less than or equal to 2mm, and the needle core is electrically connected to the plug-in terminal;
[0010] The needle core includes an insulating part and an exposed part in sequence along the direction relatively away from the plug end. One end of the exposed part is connected to the end of the insulating part away from the plug end. The surface of the insulating part is covered with an insulating layer. The length of the exposed part is less than or equal to 10 mm.
[0011] The needle core is made of 1Cr18Ni9Ti stainless steel.
[0012] In this technical solution, by providing a disposable energy-conducting electrode, the plug-in end of which is compatible with both low-temperature plasma energy platforms and radiofrequency thermocoagulation platforms, it can be docked with the corresponding platform to perform low-temperature plasma therapy or radiofrequency thermocoagulation therapy. Therefore, when both low-temperature plasma and radiofrequency thermocoagulation treatments are required for the same location, the switching between the two treatments can be directly achieved by changing the docking relationship between the plug-in end and different platforms.
[0013] Specifically, the outer diameter of the needle core is less than or equal to 2mm to meet the requirements for insertion into the cannula and use in conjunction with it. The total length of the needle core is greater than or equal to 45mm to meet the length requirements for use as a low-temperature plasma needle knife. Meanwhile, considering that in radiofrequency thermocoagulation treatment, excessive length leads to higher energy output, and its use as a radiofrequency cannula needle could cause unnecessary damage to other surrounding tissues or nerves, an insulating layer is incorporated into the needle core, with the exposed portion being less than or equal to 10mm. This avoids excessive length of the uninsulated portion (exposed portion) and, with a simpler structure, prevents energy damage to other tissues or nerves along the puncture path.
[0014] Furthermore, since the disposable conductive electrode is installed in the radiofrequency cannula, liquid can be injected into the site before and after low-temperature plasma therapy and radiofrequency thermocoagulation, eliminating the need to replace the electrode. Therefore, the entire treatment can be performed without repeated punctures, reducing workload and lowering medical risks.
[0015] Meanwhile, the needle core is made of 1Cr18Ni9Ti stainless steel, which can be used for discharge during low-temperature plasma therapy and radiofrequency thermocoagulation. This material also exhibits high stability, meeting the basic requirements of medical consumables and reasonably reducing electrode manufacturing costs. This allows for a reduction in the cost of using this disposable energy-conducting electrode, even if its usage is changed to single-use and disposable, compared to the cost of currently available reusable electrodes. Furthermore, single-use and disposable design saves on sterilization costs, further improving work efficiency and reducing overall treatment costs.
[0016] Preferably, the disposable conductive electrode further includes a needle holder, and the plug end, the needle holder, and the needle core are connected in sequence, wherein the needle holder is made of PC plastic.
[0017] In this technical solution, the above settings facilitate the stabilization of the needle core and reduce the overall manufacturing cost of the needle holder and even the disposable conductive electrode.
[0018] Preferably, the total length of the needle core is less than or equal to 150 mm.
[0019] In this technical solution, the above settings make the disposable conductive electrode suitable for most puncture situations, and excessive length is not conducive to its use.
[0020] Preferably, the outer diameter of the needle core is in the range of 0.410mm-0.910mm.
[0021] In this technical solution, the above settings enable the disposable conductive electrode to be compatible with most puncture situations, ensuring that the needle core has sufficient strength for puncture and is easy to adapt to existing cannulas.
[0022] Preferably, the end of the exposed portion away from the plug-in end is pointed.
[0023] In this technical solution, the above settings facilitate puncture of the exposed part to the tissue or nerve to be treated, accurately outputting energy, while the insulating part can prevent energy from damaging other tissues or nerves along the puncture path.
[0024] Preferably, the insulating layer is made of PET or Teflon.
[0025] In this technical solution, the above settings can further protect other tissues or nerves along the puncture path, avoiding puncture, while being relatively reliable in terms of toxicity and allergenicity, and meeting medical safety requirements.
[0026] Preferably, the thickness of the insulating layer is in the range of 4μm-6μm.
[0027] In this technical solution, the above settings can prevent the insulation layer from being too thin, which could lead to breakdown, or too thick, which could affect the puncture effect.
[0028] Preferably, the length of the exposed portion is greater than or equal to 5 mm.
[0029] In this technical solution, the above settings facilitate precise energy output from the exposed area to the tissue or nerve to be treated, with a suitable range.
[0030] A cryogenic plasma device includes a cryogenic plasma energy platform and a disposable energy-conducting electrode as described above, wherein the cryogenic plasma energy platform is adaptable to the plug-in terminal.
[0031] In this technical solution, by providing the low-temperature plasma device, repeated punctures can be avoided in low-temperature plasma therapy, reducing workload, lowering medical risks, and reducing consumable costs.
[0032] A radio frequency thermocoagulation device includes a radio frequency thermocoagulation platform and a disposable energy-conducting electrode as described above, wherein the radio frequency thermocoagulation platform is adaptable to the plug-in terminal.
[0033] In this technical solution, by providing the radiofrequency thermocoagulation device, the disposable energy-conducting electrodes can be replaced with disposable ones during radiofrequency thermocoagulation treatment, saving sterilization costs, further improving work efficiency, and reducing the overall treatment cost.
[0034] The positive and progressive effects of this utility model are as follows:
[0035] By providing this disposable conductive electrode, its connector can be adapted to both low-temperature plasma energy platforms and radiofrequency thermocoagulation platforms. It can be docked with the corresponding platform to perform either low-temperature plasma therapy or radiofrequency thermocoagulation. Therefore, when both low-temperature plasma and radiofrequency thermocoagulation treatments are needed at the same site, switching between the two treatments can be achieved directly by changing the connection relationship between the connector and different platforms. It also meets the length requirements for insertion into the cannula, use with the cannula, and as a low-temperature plasma needle knife, avoiding unnecessary damage to surrounding tissues or nerves during radiofrequency thermocoagulation. It also eliminates the need for repeated punctures, reducing workload and medical risks. Furthermore, it reasonably reduces the manufacturing and usage costs of the electrode, further improving work efficiency and lowering overall treatment costs. Attached Figure Description

[0047] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0048] like Figure 1 , Figure 2 As shown, this embodiment provides a disposable energy-conducting electrode, which includes a plug end 1 and a needle core 2. The plug end 1 can be adapted to a low-temperature plasma energy platform and a radio frequency thermocoagulator platform.
[0049] The needle core 2 is electrically connected to the plug terminal 1. The material of the needle core 2 is 1Cr18Ni9Ti stainless steel (compliant with GB1220-1992 standard).
[0050] Thus, by providing this disposable energy-conducting electrode, since the plug-in end 1 of the disposable energy-conducting electrode can be adapted to both low-temperature plasma energy platforms and radiofrequency thermocoagulation platforms, it can be docked with the corresponding platform to perform low-temperature plasma therapy or radiofrequency thermocoagulation therapy. Therefore, when both low-temperature plasma and radiofrequency thermocoagulation treatments are required for the same site, the two treatments can be switched directly by changing the connection relationship between the plug-in end 1 and different platforms.
[0051] Furthermore, since the disposable conductive electrode is installed in the radiofrequency cannula, liquid can be injected into the site before and after low-temperature plasma therapy and radiofrequency thermocoagulation, eliminating the need to replace the electrode. Therefore, the entire treatment can be performed without repeated punctures, reducing workload and lowering medical risks.
[0052] Meanwhile, the needle core 2 is made of 1Cr18Ni9Ti stainless steel, which can be used for discharge during low-temperature plasma therapy and radiofrequency thermocoagulation. This material also exhibits high stability, meeting the basic requirements of medical consumables and reasonably reducing the manufacturing cost of the electrode (typically, the unit price of the original electrode is around 8000 yuan / piece, while the unit price of the disposable conductive electrode in this embodiment is around 2000 yuan / piece). This allows the cost of using the disposable conductive electrode to be reduced even if it is changed to single-use and disposable, compared to the reusable electrodes currently available. Furthermore, single-use and disposable design also saves on sterilization costs, further improving work efficiency and reducing overall treatment costs.
[0053] In this embodiment, the disposable conductive electrode also includes a needle holder 3. The insertion end 1, needle holder 3, and needle core 2 are connected in sequence. The needle holder 3 is made of PC plastic (i.e., polycarbonate plastic). This facilitates the stabilization of the needle core 2 and reduces the overall manufacturing cost of the needle holder 3 and even the disposable conductive electrode.
[0054] In this embodiment, the disposable conductive electrode also includes an electrode handle 4 and a cable 5. The plug end 1, cable 5, electrode handle 4, needle seat 3, and needle core 2 are connected sequentially. This arrangement facilitates the user's grip on the electrode handle 4 for connection and puncture operations. Furthermore, the cable 5 supports stable energy delivery from 5W to 50W, further improving the adaptability of this disposable conductive electrode to various low-temperature plasma energy platforms and radiofrequency thermocoagulation platforms. Of course, in other embodiments, the disposable conductive electrode can be further equipped with other structures adapted for treatment.
[0055] In this embodiment, the total length L1 of the needle core 2 is 48mm. This allows the disposable conductive electrode to be suitable for shallower punctures. Of course, in other embodiments, the total length of the needle core can also be other values within the range of 45mm-150mm to suit most puncture situations; considering the standardized supply of medical devices, three types of needle cores with total lengths of 48mm, 98mm, and 142mm are usually available.
[0056] In this embodiment, the outer diameter D1 of the needle core 2 is 0.413 mm to accommodate shallower punctures with lower strength requirements. Of course, in other embodiments, the outer diameter of the needle core can also be any value within the range of 0.410 mm to 0.910 mm to accommodate most puncture situations, ensuring the needle core has sufficient strength for puncture (typically the thinnest model is 27G with an outer diameter of 0.413 mm; more preferably, a model of 22G (outer diameter 0.700 mm) or higher should be chosen to avoid the risk of breakage during puncture due to using excessively thin needle cores), and to facilitate compatibility with existing sheaths. The tube (usually the thickest model is 14G with an outer diameter of 2mm; thicker models cannot be inserted into existing cannulas; however, considering the convenience of puncture, 16G with an outer diameter of 1.6mm or finer needle cores are usually selected); considering the standardized supply of medical devices, four types of needle cores are usually available: 20G (outer diameter of 0.908mm), 21G (outer diameter of 0.819mm), 24G (outer diameter of 0.566mm), and 27G (outer diameter of 0.413mm).
[0057] In this embodiment, the needle core 2 also includes an exposed portion 21 and an insulating portion 22. One end of the exposed portion 21 is connected to the end of the insulating portion 22 away from the insertion end 1, and the other end of the exposed portion 21 is pointed. This facilitates the exposed portion 21 to be punctured to the tissue or nerve to be treated, allowing for precise energy output, while the insulating portion 22 prevents energy from damaging other tissues or nerves along the puncture path.
[0058] In this embodiment, the surface of the insulating part 22 is covered with an insulating layer 23. This allows for a simpler structure while avoiding energy damage to other tissues or nerves along the puncture path.
[0059] In this embodiment, the insulating layer 23 is made of PET (polyethylene terephthalate). This provides further protection for other tissues or nerves along the puncture path, preventing puncture, while also being reliable in terms of toxicity and allergenicity, meeting medical safety requirements. Of course, in other embodiments, the insulating layer can also be made of Teflon or other materials with similar properties.
[0060] In this embodiment, the thickness D2 of the insulating layer 23 is 5 μm. This avoids the insulating layer 23 being too thin, which could lead to breakdown, or too thick, which could affect the puncture effect. Of course, in other embodiments, the thickness of the insulating layer can also be other values in the range of 4 μm to 6 μm.
[0061] In this embodiment, the length L2 of the exposed portion 21 is 5 mm. This allows the exposed portion 21 to accurately deliver energy to the tissue or nerve to be treated within a suitable range. Of course, in other embodiments, the length of the exposed portion can also be other values within the range of 5 mm to 10 mm.
[0062] Specifically, in low-temperature plasma therapy, there are certain requirements for the length of the low-temperature plasma needle knife; it cannot be too short, otherwise it will not be able to fit the tissue to be entered. For use as a needle knife, the total length of the needle core 2 is in the range of 45mm-150mm. However, in radiofrequency thermocoagulation therapy, the energy generated is higher, and an excessively long radiofrequency cannula can cause unnecessary damage to other surrounding tissues or nerves. Therefore, in this embodiment, an insulating layer 23 is provided on the needle core 2, covering the entire insulating portion 22, so that the length of the exposed portion 21 at the front end is 5mm-10mm, thus avoiding excessive damage.
[0063] This embodiment also provides a low-temperature plasma device, which includes a low-temperature plasma energy platform and a disposable conductive electrode as described above. The low-temperature plasma energy platform is compatible with the plug-in terminal 1. This avoids repeated punctures during low-temperature plasma therapy, reducing workload, lowering medical risks, and reducing consumable costs.
[0064] This embodiment also provides a radiofrequency thermocoagulation device, which includes a radiofrequency thermocoagulator platform and a disposable energy-conducting electrode as described above. The radiofrequency thermocoagulator platform is compatible with the plug-in terminal 1. This allows the electrode to be used only once during radiofrequency thermocoagulation treatment, saving on sterilization costs, further improving work efficiency, and reducing overall treatment costs.
[0065] In this embodiment, if there is a need to switch between low-temperature plasma therapy and radiofrequency thermocoagulation therapy for the same area, simply disconnect the plug 1 from the low-temperature plasma energy platform or the radiofrequency thermocoagulator platform and connect it to another platform to complete the switch. No secondary puncture is required, reducing workload and lowering medical risks.
[0066] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
