Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and more specifically, to a plasma electrode for treating ear diseases. Background Technology

[0002] The basic principle of low-temperature plasma surgical electrodes is to utilize the energy generated by a plasma generator to form a highly concentrated plasma layer between the plasma surgical electrode and the tissue. The plasma in this layer is accelerated by an electric field, possessing sufficient energy to pulverize the organic molecular chains within the tissue, causing the tissue to decompose into simple molecules, atoms, or low-molecular-weight gases, thereby achieving ablation and cutting. Because the current does not flow directly through the tissue, tissue heating is minimal, resulting in a low treatment temperature (40–70°C) that maintains cell activity. Simultaneously, due to the insulating effect of plasma and the thermal effect of the current, blood vessels can rapidly constrict and coagulate, achieving intraoperative hemostasis.

[0003] Among common ear diseases, secretory otitis media and middle ear infections are mainly caused by bacterial infections, such as Pseudomonas aeruginosa. Traditional treatments require applying sterilizing agents to the ear, and in severe cases, surgery is needed to scrape away the wound and perform sterilization. However, these procedures are very inconvenient. Low-temperature plasma radiofrequency ablation can quickly sterilize the ear. However, the electrode tip of plasma surgery needs to be replaced frequently, and common electrode tip replacements require circuit connections, which is not convenient. Based on the above problems, we provide a plasma electrode for the treatment of ear diseases. Summary of the Invention

[0034] Example 1

[0035] This invention discloses a plasma electrode for treating ear diseases. (See reference...) Figures 1 to 5As shown, a plasma electrode for treating ear diseases includes a handheld part 1 and a curved tube part 2. The tail of the curved tube part 2 is installed in the handheld part 1. The curved tube part 2 includes a tube body 21, a bend 22, and a blade 23. A corrosion-resistant metal tube 2101 is installed inside the tube body 21. A spiral metal wire 2102 is arranged in the gap between the tube body 21 and the metal tube 2101. The spiral metal wire 2102 is made of shape memory alloy material. The blade 23 includes a fixed end 2301 and a disassembly end 230. 2. Inside the disassembly end 2302, a Yankee suction tube 2308 is also provided. The end of the Yankee suction tube 2308 abuts against the insulating sleeve 2307. Inside the disassembly end 2302, a connecting tube 2309 connected to the Yankee suction tube 2308 is also installed. Inside the tube body 21, a delivery tube 2310 is provided to mate with the connecting tube 2309. The tail end of the delivery tube 2310 extends into the handheld part 1 and connects to the peristaltic pump 14. The handheld part 1 includes a handle. 11. The mating end 12 and the threaded head 13 are connected. The tail end of the pipe body 21 is installed inside the threaded head 13, and the front end of the mating end 12 extends forward with an internal threaded sleeve 1201. The threaded head 13 is threadedly fitted onto the internal threaded sleeve 1201. A conductive slip ring 1202 is also installed on the front end of the internal threaded sleeve 1201. Specifically, in order to maintain a seal between the mating end 12 and the handle 11, an inner sleeve 1101 extends forward from the front end of the handle 11. A sleeve is fitted onto the inner sleeve 1101. Two sets of sealing rings 1102 and mating ends 12 are fitted onto the inner sleeve 1101. In order to facilitate the absorption of tissue fluid and cleaning solution from the ear wound through the curved tube 2, a peristaltic pump 14 is also installed at the tail end of the handle 11. When the peristaltic pump 14 is working, it can absorb tissue fluid and cleaning solution used for disinfection from the ear wound through the delivery tube 2310, the connecting tube 2309 and the Janksch suction tube 2308 inside the tube body 21, so as to maintain a sterile environment in the ear.

[0036] Example 2

[0037] Reference Figures 3 to 7As shown, based on Embodiment 1, the cutter head 23 includes a fixed end 2301 and a disassembly end 2302. A metal bent tube 2201 is fitted inside the bent head 22. The fixed end 2301 is mounted on the bottom end of the metal bent tube 2201. Magnetic rings 2303 are installed on the near ends of both the fixed end 2301 and the disassembly end 2302. Helical toothed rings 2304 are provided on the adjacent sides of the two magnetic rings 2303. The teeth of the two helical toothed rings 2304 mesh with each other. The helical toothed rings 2304 can cooperate with each other. When the disassembly end 2302 is installed, the two magnetic rings 2303 attract each other, and the two helical toothed rings 2304 also move closer to each other. Due to the meshing cooperation of the two helical toothed rings 2304, the disassembly end 2302 can be kept rotating while... The electrode rod 2306, which is attached to the fixed end and located inside the disassembly end 2302, can contact the spring plate 2313 in the power connection device during rotation, thereby connecting the circuit. Multiple insert blocks 2305 are also connected to the back of the magnetic ring 2303. An insert groove adapted to the insert block 2305 is provided on the side of the fixed end 2301 opposite to the disassembly end 2302. The interplay between the insert groove and the insert block 2305 ensures that the disassembly end 2302 rotates with the magnetic ring 2303, facilitating the rotation of the electrode rod 2306. Two electrode rods 2306 are also installed inside the disassembly end 2302, and the fixed end 2301 is equipped with a power connection device that matches the electrode rod 2306. This power connection device includes an electrode ring 231. 2. Two spring plates 2313 are connected to the electrode rod 2306. A slot 2315 is provided in the middle of each spring plate 2313 to engage and limit the electrode rod 2306. The electrode rod 2306 is inserted into the power receiving device and rotated to engage in the slot 2315. An insulating ring 2311 is fitted onto the outside of the power receiving device and installed inside the fixed end 2301. To facilitate electrical connection between the electrode rod 2306 and the power receiving device, the electrode ring 2312 is divided into two parts by two cross-sectional grooves. Circuit lines 2316 are connected to the two parts of the electrode ring 2312, respectively, and are connected to the positive and negative terminals of the power supply. Spring plates 2313 are connected to the two parts of the electrode ring 2312, with the middle of each spring plate 2313 connected to the electrode ring 2312. A support spring 2314 is also installed between the two electrode rods 2306 and the two spring plates 2313 respectively. When the two electrode rods 2306 contact the two spring plates 2313 respectively, they can be electrically connected to the positive and negative terminals of the power supply, thereby generating a plasma jet between the two electrode rods 2306. In addition, the front end of the electrode rod 2306 extends to the outside of the disassembly end 2302, and the front end of the two electrode rods 2306 is fitted with the same insulating sleeve 2307. The front end of the insulating sleeve 2307 is open and has a channel for the plasma jet to flow inside. Since the disassembly end 2302 is made of ceramic material, a plasma jet will be generated between the electrode rods 2306 extending outside the disassembly end. With the cooperation of the insulating sleeve 2307, the plasma jet can be guided to be ejected in the direction of the front opening.It can be easily sprayed directly onto the affected wound for sterilization and treatment.

[0038] Example 3

[0039] Reference Figure 8 and Figure 9 As shown, in the machine tools of Embodiment 1 and Embodiment 2, a medical camera 201 is also installed on the bending section 2. The medical camera 201 is installed on the tube body 21 through the top hoop 202. The top of the hoop 202 is provided with an opening groove. The top of the two sides of the opening groove are respectively connected to the movable strip 203 and the surrounding frame 204. The movable strip 203 is located inside the surrounding frame 204. A pressure roller 207 is also horizontally slidably installed in the surrounding frame 204. The pressure roller 207 is set close to the back of the movable strip 203. An adjusting bolt 206 is also threaded on the surrounding frame 204. The bottom end of the adjusting bolt 206 extends into the surrounding frame 204 and is connected to a triangular block 205. The triangular block 205 cooperates to push the pressure roller 207 to slide horizontally in the surrounding frame 204.

[0040] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0041] The implementation principle of a plasma electrode for treating ear diseases according to an embodiment of the present invention is as follows: During operation, the disassembly end 2302 of the blade 23 is first installed on the fixed end 2301. During installation, the disassembly end 2302 is aligned with the fixed end 2301, and the electrode rod 2306 is inserted into the power receiving device inside the fixed end 2301. Under the attraction of the two magnetic rings 2303, the disassembly end 2302 will approach the fixed end 2301. The magnetic rings 2303 are also provided with mutually cooperating helical toothed rings 2304. As the two magnetic rings 2303 approach each other, the helical toothed rings 2304 will also contact and gradually mesh together. This allows the disassembly end 2302 to rotate while approaching and adhering to the fixed end 2301, remaining fixed. During the overcharge process of 2302 rotating close to the disassembly end 2302, the electrode rod 2306 will rotate with the disassembly end 2302, so that the electrode rod 2306 can contact the spring plate 2313. The spring plate 2313 is installed in the electrode ring 2312. The electrode ring 2312 is divided into two parts by a cross-sectional groove and connected to the positive and negative terminals of the power supply respectively. This makes the electrode rod 2306 electrically connected to the positive and negative terminals of the power supply, which facilitates the generation of plasma jet. In order to guide the plasma jet to spray towards the wound in the ear, an insulating sleeve 2307 is also fitted on the outer end of the two electrode rods 2306. The front end of the insulating sleeve 2307 is provided with an opening, and the inside of the insulating sleeve 2307 is provided with a channel to guide the plasma jet, which facilitates the guidance of the plasma jet.

[0042] In addition, for accurate and intuitive treatment, a medical camera 201 is also installed on the tube body 21. The medical camera 201 is installed on the tube body 21 through the hoop 202. The triangular block 205 can be moved up and down by rotating the adjusting bolt 206. When the triangular block 205 pushes the squeezing roller 207 downward, it can squeeze the movable strip 203, thereby keeping the movable strip 203 in contact with the inner wall of the surrounding frame 204, thus fixing it on the tube body 21. The position of the camera installed on the tube body 21 can be adjusted at will, which is convenient for intuitive treatment of the wound in the ear.
