Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multi-directional array plasma jet device for the treatment of hemorrhoids. Background Technology

[0002] Hemorrhoids are a common disease of the anorectal region, causing great inconvenience to patients' lives. In recent years, low-temperature plasma jet technology has been gradually applied to the anti-inflammatory, antibacterial, and healing-promoting treatment of hemorrhoids, showing promising therapeutic prospects. Existing plasma treatment equipment typically generates a jet in only one direction. Doctors need to manually adjust the irradiation angle frequently during operation, making it difficult to ensure that the jet fully covers the circumferential hemorrhoid area and multiple hemorrhoids. The unidirectional jet mode cannot achieve large-area uniform irradiation, easily resulting in missed areas, making the overall operation very cumbersome, lengthening the time of each irradiation session, and reducing overall work efficiency.

[0003] Meanwhile, when traditional treatment devices are inserted into the rectal cavity, the hard outer shell of the device directly rubs against the delicate intestinal mucosa, easily scratching normal intestinal wall tissue and increasing the patient's pain during treatment. These devices lack effective isolation and protection structures at the front end, failing to expose the affected tissue separately. While the jet irradiates the hemorrhoid lesions, it inevitably acts directly on the normal mucosa in non-lesion areas, posing a risk of damaging surrounding healthy tissue, significantly reducing the safety of the entire treatment process, and easily causing secondary physiological harm to the patient.

[0004] Furthermore, the plasma process of ionizing the working gas and treating hemorrhoid tissue inevitably generates trace amounts of waste gas. Past treatment equipment lacked a sealed collection and internal purification structure for these waste gases. The generated waste gas would directly leak into the external environment through the rectal cavity and diffuse into the air of the examination room. This waste gas not only emits an unpleasant odor but also degrades the cleanliness of the surrounding air, causing an unpleasant breathing experience for both doctors and patients. Currently, there is an urgent need for a new device that features omnidirectional uniform irradiation, a tissue isolation and anti-scratch structure, and integrated waste gas purification functions to overcome these technical bottlenecks. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-directional array plasma jet device for hemorrhoid treatment. This device solves the problems of existing plasma treatment equipment that only generates jets in a single direction, resulting in incomplete coverage of the circumferential hemorrhoid area; the hard outer shell directly rubbing against the intestinal mucosa, causing damage to normal tissue; and the lack of a waste gas collection and purification structure, leading to leakage of treatment waste gas into the outside world and compromising air cleanliness.

The device generates a high-frequency, high-voltage electric field, which breaks down the flowing gas to generate plasma. The through-hole 14 is used to disperse the plasma jet generated inside the tube to the surrounding area, forming a multi-directional array spray. The rotating mechanism is used to drive the plasma generator to rotate slowly, so that the outwardly ejected plasma jet can perform a 360-degree uniform scan irradiation of the annular hemorrhoids or multiple hemorrhoids in the cavity without dead angles. The treatment window 8 is used to compress the diseased hemorrhoid tissue into the cover after the device is placed into the cavity, thereby accurately exposing it to the range of action of the jet generated by the through-hole 14.

The tungsten needle 19 is 15cm long and 2mm in diameter. The distance between the tip of the tungsten needle 19 and the nozzle at the bottom of the quartz dielectric tube 16 is 2mm.

[0025] The quartz dielectric tube 16 is wrapped with an annular electrode 9, which is made of copper foil. The annular electrode 9 and the tungsten needle 19 form a needle-ring discharge structure. There are 12 through holes 14, which are divided into upper and lower layers. Each layer has 6 through holes 14, which are symmetrically distributed.

[0026] Specifically, the tungsten needle 19 serves as the tip for applying high voltage, generating stable low-temperature plasma with its set size and discharge gap; the ring electrode 9 serves as the grounding terminal to provide a potential difference, which, together with the attached copper foil material, forms an extremely strong local electric field inside and outside the quartz dielectric tube to break down the working gas; the needle-ring discharge structure is used to construct a stable atmospheric pressure gas ionization region inside the quartz dielectric tube; the through hole 14 is used to guide the plasma excited inside the quartz dielectric tube to the surrounding area, forming a multi-directional radiation jet with the double-layer symmetrically distributed micro-apertures, thereby achieving large-area and seamless uniform coverage and sterilization treatment of hemorrhoid lesions in the rectal cavity.

Each treatment window 8 has an ultra-thin silicone skirt embedded along its edge, with a thickness of 0.2mm. The inner surface of the ultra-thin silicone skirt is coated with a hydrogel lubricating layer. The outer surface of the treatment window 8 is covered with a peelable biofilm sticker, which covers and seals the treatment window 8.

[0028] Specifically, the shield 7 serves as a disposable consumable to isolate the internal high-voltage discharge components, preventing cross-infection and providing a safe, rigid support for the device's entry into the human body cavity; the treatment window 8 allows the hemorrhoidal tissue at the affected area to protrude into the shield to receive direct irradiation from the plasma jet when the device is inserted into the rectal cavity, while effectively isolating and protecting the normal intestinal wall mucosa in non-lesion areas; the ultra-thin silicone skirt enhances the local seal when the treatment window 8 adheres to the affected tissue, preventing the leakage of waste gas and avoiding scratches to the fragile intestinal mucosa by the edges of the holes in the rigid ABS material; the hydrogel lubricating layer reduces the mechanical friction generated when the device is inserted into the hemorrhoid area, thereby effectively reducing patient discomfort and pain during treatment; the tearable biofilm sticker seals the treatment window 8 during the product's standby phase, thereby maintaining the moisture and sterility of the internal hydrogel lubricating layer.

[0029] Please see the appendix Figure 1 and attached Figure 2 The plasma generator also includes a housing 1, which is located outside the overall device. The top outer side of the housing 1 is provided with a positive power interface 2, a negative power interface 3 and an air inlet 4. The outer casing 1 has a fixing block 10 and a fixing circular plate 17 inside. The fixing block 10 has an airflow groove 11 inside, which is connected to the air inlet 4. The plasma generator also has a connecting block 18 and a threaded groove block 12 inside. The top of the quartz dielectric tube 16 is fixedly connected to a threaded clamping block 15, and the quartz dielectric tube 16 is threadedly connected to the threaded groove block 12 through the threaded clamping block 15. The top of the high-voltage electrode passes through the center of the connecting block 18 and the threaded groove block 12 and extends downward into the interior of the quartz dielectric tube 16.

[0030] Specifically, the outer shell 1 is used to cover and protect the core gas path and circuit components inside the plasma generator, while providing a mounting base for each interface and internal fixing component; the positive power interface 2 and the negative power interface 3 are used to connect to external high-frequency high-voltage power supply equipment to provide excitation power for the internal high-voltage electrode and ground electrode; the air inlet 4 is used to connect to the external gas pool to introduce the working gas into the device; the fixing block 10 and the fixing circular plate 17 are used to provide stable support and limit the gas path and circuit structure in the internal space to prevent internal loosening of the device during use and rotation; the airflow groove 11 is used to guide the gas entering from the air inlet 4, so that the gas is smoothly and evenly conducted downward to the quartz dielectric tube 16; the connecting block 18 is used to guide and position the high-voltage electrode passing through, ensuring that the high-voltage electrode is always on the central axis of the quartz dielectric tube 16; the threaded clamp block 15 cooperates with the threaded groove block 12 to realize the detachable spiral fastening connection between the quartz dielectric tube 16 and the internal frame, ensuring the connection sealing under high-pressure gas flow environment, and facilitating the independent disassembly and replacement of the quartz dielectric tube 16 in the future.

[0031] Please see the appendix Figure 4 The base 20 is equipped with a motor, and the rotating mechanism includes a rotating base 5, which is located above the base 20. The motor is used to drive the rotating base 5 to rotate. A limiting rotation protrusion 13 is fitted on the lower outer side of the plasma generator, and the limiting rotation protrusion 13 is engaged with the rotating base 5; the shielding cover 7 is fitted on the outside of the rotating base 5, and the shielding cover 7 has a medical-grade silicone sealing pipe inside.

[0032] Specifically, the motor provides power for the rotation of the entire device; the rotating base 5 receives the transmission power from the motor and drives the plasma generator above to rotate; the limiting rotating protrusion 13 securely engages and fixes the plasma generator with the rotating base 5, establishing a stable mechanical connection and preventing slippage and displacement of the device during operation; the medical-grade silicone sealing pipe is used to establish an airtight isolation layer inside the shielding cover 7, strictly blocking internal airflow and preventing waste gas generated during treatment from leaking into the external environment.

[0033] Please see the appendix Figure 4 It also includes a gas tank 23 and a flow controller 22; A flow controller 22 is connected between the gas pool 23 and the air inlet 4; the gas pool 23 is filled with working gas, which is composed of one or more of helium, argon, rare gases, oxygen, nitrogen and air.

[0034] It also includes a grounding electrode 6 and an exhaust gas purifier 21; the grounding electrode 6 is located on the periphery of the bottom of the plasma generator; the exhaust gas purifier 21 is connected to the internal space of the shield 7, and a filter screen is provided inside the exhaust gas purifier 21.

[0035] Specifically, the gas pool 23 is used to store the working gas required to generate plasma, providing a continuous gas source for the entire device; the flow controller 22 is used to control the flow rate and type of working gas entering the inlet 4, and to adjust the dosage of active particles in the plasma jet to meet the treatment needs of different conditions; the grounding electrode 6 is used to provide a safe grounding return path, ensuring the electrical safety of the device during high-voltage discharge and stabilizing the local electric field; the exhaust gas purifier 21 is used to collect the waste gas generated inside the shield 7 during treatment, preventing the waste gas from being directly discharged into the external environment; the filter screen is used to intercept and filter the waste gas entering the exhaust gas purifier 21, ensuring the cleanliness of the final discharged gas.

[0036] Working Principle: This multi-directional array plasma jet device uses a motor inside the base 20 to drive the rotating base 5, which in turn rotates the plasma generator, performing a comprehensive scan of the hemorrhoid area to be treated. Working gas supplied by the gas tank 23, after being regulated by the flow controller 22, enters the quartz dielectric tube 16. When the positive and negative power interfaces 2 and 3 are energized, a high-frequency, high-voltage electric field is generated between the tungsten needle 19 and the ring electrode 9, ionizing the working gas and generating low-temperature plasma. The plasma jet is ejected from the through-hole 14 and acts on the hemorrhoid tissue through the treatment window 8, achieving anti-inflammatory, antibacterial, and healing-promoting treatment. Simultaneously, during the continuous plasma jet treatment, waste gas is generated internally. This waste gas is collected through the isolation space inside the shield 7 and filtered and purified by the exhaust gas purifier 21 before being discharged into the external environment. The treatment window 8 on the surface of the shield 7, combined with an ultra-thin silicone skirt, not only exposes the hemorrhoid tissue but also prevents mechanical damage to the normal intestinal mucosa during insertion and rotation, effectively improving the safety and comfort of the treatment.

[0037] When plasma jet irradiation treatment of hemorrhoids is required, working gas must first be delivered under the drive of the gas system. By activating the flow controller 22, the working gas stored inside the gas tank 23 flows into the air inlet 4. The airflow entering the air inlet 4 flows downward along the airflow groove 11 inside the fixed block 10, and finally smoothly enters the interior of the quartz dielectric tube 16. After the gas fills the interior of the quartz dielectric tube 16, power is supplied to the positive power interface 2 and the negative power interface 3 through an external power supply. The power supply voltage is applied to the tungsten needle 19 located at the center of the quartz dielectric tube 16 and the annular electrode 9 wrapped around it, creating a strong discharge electric field between the tip of the tungsten needle 19 and the annular electrode 9. The working gas passing through the electric field is instantly ionized and converted into a low-temperature plasma state. The generated plasma jet is then ejected outward at high speed through multiple through holes 14 arranged in a circular array on the bottom sidewall of the quartz dielectric tube 16, forming a multi-directional arrayed jet source.

[0038] The generated multi-directional array plasma jet needs to uniformly cover the hemorrhoid lesions within the rectal cavity, requiring the base 20 to work in conjunction with the shield 7 for positioning and rotational scanning. Before treatment, the peelable biofilm sticker covering the outer surface of the treatment window 8 on the side of the shield 7 is first peeled off, and the shield 7 with a hydrogel lubricating layer is pushed into the patient's rectal cavity. The hemorrhoid tissue inside the rectum is compressed and protrudes into the internal space of the treatment window 8. Then, the motor inside the base 20 is activated, and the motor drives the rotating base 5 above to rotate slowly. Because the limiting rotation protrusion 13 on the lower outer side of the plasma generator is engaged with the rotating base 5, the rotation of the rotating base 5 will synchronously drive the entire internal plasma generator to rotate 360 ​​degrees. During the rotation, the plasma jet continuously ejected from the through hole 14 passes through the treatment window 8 to uniformly irradiate the protruding hemorrhoid tissue without dead angles, ensuring that multiple hemorrhoids receive sufficient coverage of active particles.

[0039] Because the plasma jet continuously reacts in the closed intestinal environment, it generates a small amount of waste gas. Simultaneously, the rotating motion of the device causes relative friction with the intestinal wall, necessitating exhaust treatment by the exhaust gas purifier 21 and safety protection in conjunction with the shielding cover 7. While the plasma generator is discharging, the treatment waste gas, blocked and sealed within the internal space by the shielding cover 7 and medical-grade silicone sealing pipes, flows back through the internal exhaust channel and enters the exhaust gas purifier 21, which is connected to the internal space of the shielding cover 7. The filter inside the exhaust gas purifier 21 comprehensively intercepts and filters the incoming waste gas, discharging the harmlessly treated gas into the external environment to prevent waste gas pollution and leakage. Throughout the insertion and rotation irradiation process, the 0.2mm thick ultra-thin silicone skirt embedded around the edge of the treatment window 8 softens and wraps the hard edges of the porous medical-grade ABS plastic, preventing sharp edges from scratching the delicate intestinal wall tissue. Combined with the hydrogel lubricating layer coated on the surface, this significantly reduces mechanical friction, ensuring stable operation throughout the entire treatment process.
