Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a sinus treatment tube assembly and a sinus treatment device. Background Art

[0002] Deep tissue sinuses are common in various skin and soft tissue injuries, such as trauma, burns, bedsores, diabetic foot, and difficult-to-heal postoperative incisions. A sinus tract is a potential blind tube that opens to the body surface and does not communicate with hollow internal organs, formed after infected and necrotic tissue is excreted through the body's surface. It can occur in soft tissue, fat, muscle, and even bone. Common examples include abdominal wall sinuses caused by poor drainage after infected abdominal wall incisions or foreign matter left in the incision; chronic sinuses caused by bone necrosis due to fractures or other causes; and chronic sinuses caused by foreign matter left after trauma or surgery.

[0003] Clinically, deep wounds caused by diseases such as serous mastitis and anal fistulas present many difficult problems. These wounds often have a lot of exudate, which not only affects the wound healing environment, but also easily breeds bacteria and causes infection. Due to factors such as the presence of infection and the depth of the wound, the wound healing process is extremely slow, and long-term drainage is required to keep the wound clean. However, existing treatment methods only exist at the drainage level and cannot provide further treatment effects for the wound. Summary of the Invention

[0004] The present invention provides a sinus treatment tube assembly and a sinus treatment device to solve the above-mentioned technical defects in the prior art. The sinus treatment tube assembly not only has drainage and flushing functions, but also has an additional plasma treatment function, which can exert a strong bactericidal effect and promote wound healing.

[0005] A sinus tract treatment tube assembly provided in a first aspect of the present invention includes a tube body and a plasma generator.

[0014] According to the sinus tract treatment tube assembly provided by the present invention, the treatment end is detachably connected to the tube body; and / or the treatment end is adapted to be telescopic to change its own length.

[0016] And / or, a plurality of drainage holes are arranged at intervals on the tube wall of the treatment end, and the drainage holes are arranged through the negative electrode layer, the dielectric barrier layer and the positive electrode layer.

[0017] A second aspect of the present invention provides a sinus treatment device, comprising a drainage device and any one of the sinus treatment tube assemblies, wherein the tube body of the sinus treatment tube assembly is connected to the drainage device.

[0018] The sinus treatment device provided according to the present invention also includes a power supply module, a control module, a power regulation module and a monitoring module.

The control module is used to control the power supply module, the power regulation module and the drainage device to perform corresponding operations based on the data information collected by the monitoring module.

[0019] The sinus tract treatment tube assembly provided by the present invention integrates a plasma generator at the treatment end of the tube body. The plasma generator comprises a stacked negative electrode layer, a dielectric barrier layer, and a positive electrode layer, or comprises a coplanar positive electrode and a negative electrode.

[0035] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification and features of different embodiments or examples, unless they are mutually inconsistent.

[0039] Clinically, drainage is the primary treatment for deep wounds and sinus tracts with high exudate levels, such as serous mastitis and anal fistulas. Common drainage devices include conventional drainage tubes, rubber drainage tubes, gauze drainage strips, and vacuum seal drainage (VSD) technology.

[0040] Among them, drainage tubes and drainage strips rely on the principles of siphon and gravity, and are mainly used in situations where the amount of exudate is small; they only focus on the function of wound drainage. When faced with deep wounds with a lot of exudate and easy infection, they lack the ability to process the exudate, and cannot sterilize and disinfect the wound while draining to promote wound healing, failing to fundamentally solve the problem of difficult wound healing.

[0041] A negative pressure drainage device is a medical device widely used clinically for treating deep wounds and sinus tracts. It primarily consists of a negative pressure source, a drainage tube, and a dressing. The negative pressure source creates a continuous negative pressure environment within the wound or sinus tract; under the action of negative pressure, exudate, necrotic tissue, and other fluids within the wound or sinus tract are effectively drained to the outside of the body. Unlike the aforementioned drainage tubes and drainage strips, negative pressure drainage devices have a certain therapeutic effect. In principle, a continuous negative pressure environment can promote local blood circulation. Specifically, negative pressure dilates capillaries, increasing local blood perfusion, which helps provide more nutrients and oxygen to the wound and accelerate tissue repair. Furthermore, negative pressure can reduce tissue edema, diminish bacterial growth, and mitigate the risk of infection. Furthermore, during the negative pressure adsorption process, some necrotic tissue and bacteria can be removed, facilitating wound cleansing and healing.

[0042] However, negative pressure drainage devices primarily rely on negative pressure suction to achieve drainage and partial therapeutic effects. Their therapeutic effects on wounds are primarily based on physical changes, such as improving blood circulation and removing some necrotic tissue. They lack direct wound sterilization and disinfection mechanisms, are unable to treat stubborn bacterial infections, and have limited therapeutic effectiveness. Therefore, embodiments of the present invention provide a sinus treatment tube assembly that can be used in sinus treatment devices, achieving both drainage and superior therapeutic effects.

[0043] Figure 1 It is a structural schematic diagram of a sinus treatment tube assembly provided by an embodiment of the present invention. Figure 2 It is a schematic diagram of the structural decomposition of a sinus treatment tube assembly provided by one embodiment of the present invention.

[0044] See Figure 1 and Figure 2 The present invention provides a sinus tract treatment tube assembly for transferring fluids or gases from the body to the outside of the body. This assembly is primarily used to remove abnormal accumulations within the body, such as clearing pus, blood, and exudate from surgical incisions, traumatic injuries, or infected areas to prevent the spread of local inflammation. When fluid accumulates in the pericardium, pleural cavity, or abdominal cavity, the sinus tract treatment tube assembly can be introduced to drain the accumulated fluid, reducing the burden on the heart and lungs and protecting the function of vital organs. The sinus tract treatment tube assembly can also be used to maintain a normal physiological environment, such as by helping to clear respiratory secretions and prevent lung infections.

[0045] The sinus treatment tube assembly includes a tube body 10 and a plasma generator 20. The tube body 10 comprises a main body 11 and a treatment end 12. The treatment end 12 is located at one end of the tube body 11 and is suitable for insertion into a sinus tract. The other end of the tube body 11 is suitable for connection to a drainage device. The plasma generator 20 is located at the treatment end 12 and is suitable for connection to a power module. This is equivalent to installing the plasma generator 20 at the end of the tube body 11. This device can be used to treat complex conditions such as infected sinuses, difficult-to-heal wounds, and deep tissue inflammation. It can achieve the goals of disinfection, promoting tissue repair, alleviating inflammatory responses, and promoting blood circulation.

[0046] The plasma generator 20 includes a stacked negative electrode layer 21, a dielectric barrier layer 22, and a positive electrode layer 23. The negative electrode layer 21 can be attached to the outer surface of the treatment end 12, the dielectric barrier layer 22 is located on the surface of the negative electrode layer 21, and the positive electrode layer 23 is located on the surface of the dielectric barrier layer 22. In other words, the plasma generator 20 includes the negative electrode layer 21, dielectric barrier layer 22, and positive electrode layer 23 stacked from the inside out. These layers form a dielectric barrier discharge (DBD) structure similar to a "sandwich." Dielectric barrier discharge (DBD) does not require direct contact between electrodes and the gas. Instead, it uses an insulating dielectric to separate the electrodes from the gas, preventing electrode corrosion and extending device life. When the negative electrode layer 21 and the positive electrode layer 23 are connected to a power module, the power module supplies power to the negative electrode layer 21 and the positive electrode layer 23, forming a plasma discharge zone at the treatment end 12.

[0047] Furthermore, dielectric barrier discharge operates at relatively low temperatures, making it suitable for processing sensitive or fragile materials. It produces a variety of active particles, including high-energy electrons, ions, excitons, free radicals, and reactive oxygen species. These can disrupt bacterial cell membranes, inhibit the proliferation of pathogenic microorganisms, effectively combat multidrug-resistant bacteria, and reduce the risk of infection. Reactive oxygen species stimulate fibroblast activity, promote collagen synthesis and angiogenesis, accelerate the regeneration of damaged tissue, and shorten healing time. The antioxidants and anti-inflammatory factors released by the plasma can reduce the levels of inflammatory mediators, alleviate local symptoms such as redness, swelling, and pain, improve the microenvironment, and facilitate recovery.

[0048] Among them, the DBD discharge device can be designed into different shapes and sizes according to the requirements of the application scenario, which is convenient for integration into various systems. The discharge intensity can be adjusted by changing parameters such as voltage, frequency, gas type and pressure to adapt to different application requirements.

[0049] The plasma generator 20 may also include a positive electrode or a negative electrode arranged in a coplanar manner. Compared with other discharge methods, the coplanar electrodes can achieve stable and consistent energy transfer over a wider range, avoid the formation of hot spots, and ensure uniform heating of the treatment area. They are conducive to the generation of a large number of reactive oxygen species (ROS), reactive nitrogen species (RNS) and other charged particles, effectively promoting biological effects such as wound healing, anti-inflammatory and analgesic effects.

[0050] During treatment, the wound surface is cleaned to remove foreign matter and necrotic tissue. The sinus tract treatment tube assembly is properly installed, with the treatment end 12 inserted into the affected area (wound surface) to ensure unimpeded drainage. The sinus tract treatment tube assembly is then secured in a predetermined position. While guiding the exudate outflow, power is supplied to the negative electrode layer 21 and the positive electrode layer 23 via the power module, generating plasma between the negative electrode layer 21 and the positive electrode layer 23. This plasma is then used to treat the wound surface.

[0051] It is understood that the sinus treatment tube assembly provided in the embodiments of the present invention integrates a plasma generator 20 at the treatment end 12 of the tube body 10. The plasma generator 20 comprises a stacked negative electrode layer 21, a dielectric barrier layer 22, and a positive electrode layer 23, or comprises coplanar positive and negative electrodes. When the power module supplies power to the negative electrode layer 21 (negative electrode) and the positive electrode layer 23 (positive electrode), plasma is generated between the negative electrode layer 21 (negative electrode) and the positive electrode layer 23 (positive electrode), which is used to treat the wound surface. This enables the sinus treatment tube assembly to not only provide drainage but also possess the therapeutic function of plasma, exerting a potent bactericidal effect and promoting wound healing.

[0052] Because plasma contains a large number of active particles, such as ions, electrons, free radicals, etc. These active particles can directly react with the cell walls, cell membranes or nucleic acids of microorganisms such as bacteria and viruses, destroying their structures, thereby achieving efficient sterilization and disinfection functions. In addition, plasma can also promote coagulation and wound healing by activating cell signaling pathways, promoting the release of growth factors, etc. In a humid environment with a lot of exudate, the interaction between plasma and liquid can also produce plasma water, which contains a variety of active particles with special effects, including hydroxyl free radicals, hydrogen peroxide, nitrate ions and nitrite ions, which further exert bactericidal efficacy. Therefore, the sinus treatment tube assembly provided by the embodiment of the present invention can effectively treat deep wounds and sinuses with a lot of exudate, easy infection and difficult to heal.

[0053] Figure 3 It is an axonometric cross-sectional view of a sinus treatment tube assembly provided by one embodiment of the present invention.

[0054] Continue reading Figure 1 、 Figure 2, and also see Figure 3 In some embodiments of the present invention, the plasma generator 20 further includes a protective layer 24, which is disposed on the surface of the positive electrode layer 23 or the negative electrode layer 21, that is, the protective layer 24 is disposed on the outer electrode layer. When the positive electrode layer 23 is located in the outer layer, the protective layer 24 is disposed on the surface of the positive electrode layer 23; when the negative electrode layer 21 is located in the outer layer, the protective layer 24 is disposed on the surface of the negative electrode layer 21.

[0055] The protective layer 24 directly contacts the wound surface, and needs to ensure biocompatibility and be able to withstand certain mechanical stress and chemical erosion to avoid damaging the wound surface after the protective layer 24 contacts the wound surface.

[0056] Therefore, the material of the protective layer 24 can be the same as that of the tube body 11 and the treatment end 12. Alternatively, the protective layer 24 can be constructed of materials safe for the human body, such as medical-grade silicone, PTFE, etc., to ensure safety and comfort for long-term use.

[0057] Figure 4 It is a cross-sectional view of a sinus treatment tube assembly provided by one embodiment of the present invention.

[0058] Continue reading Figure 3 , and also see Figure 4 In some embodiments of the present invention, the surface of the protective layer 24 is flush with the surface of the pipe body 11.

[0059] In other words, the protective layer 24, as well as the negative electrode layer 21, dielectric barrier layer 22, and positive electrode layer 23 that comprise the discharge portion 25, are all embedded within the tube wall of the treatment end 12, ensuring that the surface of the protective layer 24 is flush with the surface of the tube body 11. Specifically, there are no protrusions, depressions, or irregularities at the junction of the protective layer 24 and the tube body 11. This arrangement reduces friction and irritation of the sinus treatment tube assembly on surrounding tissues, minimizing damage to the skin, mucous membranes, or internal tissues, and lowering the risk of bedsores, inflammation, pain, or infection.

[0060] In some embodiments of the present invention, the shape of the discharge electrode in the plasma generator 20 is not limited to comb, grid, spiral, and honeycomb shapes.

[0061] When a high AC or DC voltage is applied between the comb-shaped electrode (positive electrode) and the ground (or negative electrode), a strong electric field forms between the electrodes. When the electric field strength exceeds the breakdown field of the gas molecules, the air molecules in the wound surface are strongly ionized, breaking down into charged particles (electrons, positive ions, and free radicals). These charged particles accelerate under the action of the electric field, colliding with other neutral molecules and generating more charged particles, forming an avalanche-like chain reaction. As the electron density increases, the local current increases dramatically, forming a discharge channel. The high temperature and high-energy electrons within the discharge channel completely ionize the gas molecules, forming a plasma composed of ions, electrons, and excited molecules. This plasma propagates outward from the discharge zone through electrodynamics and thermal diffusion, effectively sterilizing the wound surface and achieving the therapeutic goal.

[0062] The comb-tooth electrode's edge or tip, due to its small radius of curvature, significantly enhances the electric field strength, resulting in electric field concentration. This means the sharp tip of the comb-tooth electrode can locally amplify the electric field, reducing the voltage required for discharge. This allows plasma discharge to occur at lower energy input, thereby minimizing thermal damage to surrounding tissue. Furthermore, the multi-tooth arrangement can form a dense discharge array, achieving uniform coverage over a larger area, making it suitable for scenarios such as large-area wound treatment or surface processing.

[0063] When the power module provides high voltage between the spiral positive and negative electrodes, a spiral electromagnetic field is generated. Under the combined action of the strong magnetic and electric fields, the gas molecules are ionized, and electrons are stripped from the atoms, forming electrons and ions. The structure of the spiral electrode guides the electrons and ions to move along the spiral path. The charge accumulation on the spiral path triggers discharge. During the discharge process, the gas molecules are transformed into a plasma state due to ionization and heating, forming a stable plasma cloud. The plasma cloud is affected by the spiral magnetic field and propels along the spiral axis, exhibiting a spiral or vortex motion.

[0064] Since the plasma cloud generated by the spiral electrode discharge can be output in a specific direction, a magnetic component can be added to the treatment end 12. The magnetic component can generate a magnetic field, and the output direction of the plasma can be further regulated by adding the magnetic field, thereby providing targeted treatment to the wound that needs treatment.

[0065] The grid electrode typically consists of a series of interwoven metal wires or strips that alternate as positive and negative electrodes, forming multiple intersections and gaps. When an external power module applies a potential to the positive and negative electrodes, a strong electric field is established in the gaps of the grid. This electric field pulls electrons from gas molecules, causing them to separate from atoms or molecules, forming free electrons. Driven by the electric field, these free electrons accelerate and collide with more gas molecules, creating new electron-ion pairs. As the electron density increases, the local electric field becomes extremely strong, sufficient to completely break down the gas medium and trigger a discharge. The discharge path propagates along the gaps in the grid, forming numerous discrete but connected small discharge channels, increasing the effective area covered by the plasma. Within these channels, a large number of electrons, positive ions, and excited molecules gather to form a dense plasma cloud. The generated plasma diffuses from the discharge channels, fulfilling the plasma's sterilization and disinfection function.

[0066] Honeycomb electrodes typically consist of a central electrode (usually a positive electrode) surrounded by an annular or hexagonal negative electrode. The intervening space is filled with a gaseous medium. When a high-voltage power supply applies voltage between the central and peripheral electrodes, a non-uniform electric field forms between them. Due to the unique arrangement of the electrodes, the electric field is highly concentrated within each cell of the honeycomb, especially near the central electrode, where a highly concentrated electric field gradient forms. The central electrode attracts free electrons and other charged particles in the surrounding space, while the negative electrode repels these charged particles, causing charge to accumulate around the central electrode. When the electric field strength is strong enough, the gaseous medium is ionized, forming charge carriers (electrons and positive ions). The broken-down medium forms a discharge channel. The high-energy particles in the discharge channel continue to interact with other molecules, forming a large number of ions, electrons, and active species, or plasma. This plasma is not confined to the discharge channel but can diffuse into the wound surface, sterilizing and disinfecting it.

[0067] Among the various electrodes mentioned above, the comb-shaped electrode is suitable for treating local lesions because its fine tooth edges can focus the electric field, causing less damage to normal tissue around the wound. It is suitable for treating deep skin infections and can effectively kill bacteria without damaging healthy tissue. The honeycomb electrode can provide a more uniform discharge distribution and a wide plasma coverage area, making it suitable for treating sinus tracts over larger areas. The grid electrode has strong permeability and is suitable for treatment deep into tissue or in areas with complex morphology. It is beneficial for treatments that require penetration into deep tissue and can achieve deep purification and repair. The spiral electrode utilizes spiral discharge characteristics and directional plasma flow to achieve a targeted treatment effect in deep tissue. The ability to deliver plasma in a targeted manner enhances treatment accuracy and safety, making it suitable for targeted treatment.

[0068] In some embodiments of the present invention, the dielectric barrier layer 22 comprises a flexible dielectric barrier layer, the shape of which is adapted to the shape of the treatment end 12, and the negative electrode layer 21 and the positive electrode layer 23 are adapted to the shape of the dielectric barrier layer 22. The dielectric barrier layer 22 can bend to conform to the surface of the treatment end 12 of the tube body 10 and be integrated with the tube body 10.

[0069] The flexible dielectric barrier layer can be a polymer film, silicone rubber, polydimethylsiloxane, or fiber fabric. Polymer films include polyester (PET), polyimide (PI), and polytetrafluoroethylene (PTFE), all of which have good dielectric properties and mechanical stability, and can withstand certain temperatures and chemical erosion. Silicone rubber has excellent flexibility and elasticity, a wide temperature range, and is biocompatible. Polydimethylsiloxane, a material with good air permeability, is suitable for the manufacture of microstructured plasma generators. 20 Fiber fabrics can be glass fiber, carbon fiber, or the like, embedded in an insulating resin to form a composite material that maintains a certain degree of flexibility while also enhancing mechanical strength.

[0070] In some embodiments of the present invention, the treatment end 12 is detachably connected to the tube body 11. Therefore, different treatment ends 12 can be selected according to the patient's specific condition or treatment stage, such as using treatment ends 12 of different materials, sizes or special designs, to adapt to different treatment purposes.

[0071] The treatment end 12 is detachably connected to the tube body 11, and a snap-fit ​​connection can be used. A protruding snap fit is provided on the treatment end 12, and a corresponding groove or an annular collar is provided on the tube body 11. When in use, the treatment end 12 is docked with both ends of the tube body 11, and the snap fits automatically into place, completing the detachable connection.

[0072] The treatment end 12 is detachably connected to the tube body 11, and a rotary locking method can also be adopted. The connector can be interference fit at the port of the tube body 11. The outer wall of the connector is provided with a thread, and the treatment end 12 is threadedly fitted with the connector, that is, the treatment end 12 is indirectly connected to the tube body 11 through the connector.

[0073] The treatment end 12 and the tube body 11 can be detachably connected, and can also be connected magnetically, that is, strong magnets are embedded in the opposite ends of the treatment end 12 and the tube body 11, and the attraction of the strong magnets is used to maintain the physical connection between the treatment end 12 and the tube body 11.

[0074] In some embodiments of the present invention, the treatment end 12 is adapted to be retractable to change its own length to adapt to the treatment of sinus tracts of different depths, thereby improving the flexibility of use.

[0075] The treatment end 12 is adapted to be retractable to change its length, which can be achieved in the following ways:

[0076] For example, the hose of the treatment end 12 itself adopts a multi-section retractable structure, which changes its length by stretching and contracting. Alternatively, the hose of the treatment end 12 is composed of several pipe segments, and the pipe segments are connected by quick connectors. The number of pipe segments can be added or removed according to the length of use, thereby changing the total length of the hose of the treatment end 12. Alternatively, the hose of the treatment end 12 is made of a highly elastic material and can naturally retract to a small part of its original length. When in use, it can be manually or automatically extended to the required length. Alternatively, the hose of the treatment end 12 can be set in the form of a sleeve, that is, it includes an inner sleeve and an outer sleeve, the inner sleeve is connected to the tube body 11, and the outer sleeve can be slidably extended. By pulling the outer sleeve, the overall length of the hose of the treatment end 12 can be adjusted.

[0077] In some embodiments of the present invention, the treatment end 12 is not only detachably connected to the tube body 11, but the treatment end 12 is also adapted to be telescopic to change its own length. The manner of detachable connection and the manner in which the treatment end 12 is adapted to be telescopic are both described above.

[0078] Figure 5 It is a structural schematic diagram of a sinus treatment tube assembly provided by another embodiment of the present invention. Figure 6 It is a partial structural schematic diagram of a sinus treatment tube assembly provided in another embodiment of the present invention.

[0079] In some embodiments of the present invention, the treatment end 12 is provided with a plurality of drainage grooves 121 along its own axis array, the drainage grooves 121 extending along the axial direction of the treatment end 12, and the drainage grooves 121 are provided through the negative electrode layer 21, the dielectric barrier layer 22 and the positive electrode layer 23. Figures 1 to 4 shown.

[0080] In other words, small spiral or linear grooves are carved along the end of the tube 10. These grooves can ensure that liquid enters the tube 10 from multiple directions, and can keep the drainage process unobstructed even when there is tissue adhesion around the tube 10.

[0081] In some embodiments of the present invention, the tube wall of the treatment end 12 is provided with a plurality of drainage holes 122 at intervals, and the drainage holes 122 are provided through the negative electrode layer 21, the dielectric barrier layer 22 and the positive electrode layer 23. Figure 6 shown.

[0082] Equivalently, a plurality of drainage holes 122 are provided at intervals at the end of the tube body 10 , and the drainage holes 122 ensure that liquid enters the tube body 10 from multiple directions.

[0083] In some embodiments of the present invention, a plurality of drainage grooves 121 may be arranged along the axis of the treatment end 12 , and the drainage grooves 121 extend along the axial direction of the treatment end 12 . Alternatively, a plurality of drainage holes 122 may be arranged at intervals on the tube wall of the treatment end 12 .

[0084] This means that, at the distal end of the tube body 10, a combination of drainage groove 121 and drainage hole 122 is employed. In addition to the drainage groove 121, small holes can also be provided in the distal end wall of the tube body 10 to further enhance liquid collection capabilities and ensure omnidirectional drainage. The presence of drainage groove 121 and drainage hole 122 reduces single-point pressure on tissue, preventing tissue damage caused by compression from the tube wall.

[0085] In some embodiments of the present invention, a drainage channel is provided inside the tube body 11 , and the drainage channel extends to the treatment end 12 , and the drainage channel is suitable for connecting to a drainage device.

[0086] The embodiment of the present invention provides a plasma generator 20 at the end of the drainage tube, which not only has a drainage function but also has an additional plasma treatment function, which can exert a strong bactericidal effect and promote wound healing.

[0087] Figure 7 This is a schematic diagram of the structural decomposition of a sinus treatment tube assembly provided in yet another embodiment of the present invention.

[0088] See Figure 7 In some embodiments of the present invention, the tube body 11 can serve as a drainage tube 13, and the sinus treatment tube assembly also includes an irrigation tube 14, which is arranged inside the tube body 11, or arranged in parallel with the tube body 11 to form a double-tube drainage tube.

[0089] The tube body 11 (drainage tube 13 ) has a drainage channel inside, which is suitable for connecting to a drainage device; the flushing tube 14 has a flushing channel inside, which is suitable for connecting to a flushing device.

[0090] In other words, the sinus tract treatment tube assembly provided in the embodiment of the present invention not only has a drainage function, but also has a flushing function, and has an additional plasma treatment function, which can exert a strong bactericidal effect and promote wound healing.

[0091] Therefore, the sinus wound surface can be continuously or repeatedly irrigated and drained, facilitating the removal of exudates such as pus that are difficult to drain naturally. Furthermore, by flushing in liquid (such as saline, distilled water, or a medicinal solution), the plasma interacts with the liquid to produce plasma water, which contains a variety of active particles with special effects, including hydroxyl radicals, hydrogen peroxide, nitrate ions, and nitrite ions, further enhancing its bactericidal efficacy. In other words, the sinus tract treatment tube assembly provided by the present invention integrates wound irrigation and drainage with treatment, enabling plasma therapy while simultaneously irrigating and effectively draining, exerting a potent bactericidal effect and promoting wound healing.

[0092] Continue reading Figure 7 Specifically, when the irrigation tube 14 is provided inside the tube body 11 (drainage tube 13 ), the irrigation channel is formed inside the irrigation tube 14 , and the drainage channel is formed in the gap between the drainage tube 13 and the irrigation tube 14 .

[0093] A first connector 15 is fixedly mounted at the end of the drainage tube 13. This connector 15 can function as a stud and has external threads. The irrigation tube 14 is a flexible hose and is inserted into the interior of the drainage tube 13, forming a dual-lumen cannula structure with the drainage tube 13. A second connector 16 is mounted on the drainage tube 13. This connector 16 can function as a nut and has internal threads that mate with the external threads.

[0094] After the flushing tube 14 is inserted into the drainage tube 13, it is fixed by the first connecting member 15 and the second connecting member 16 to form an integral sinus treatment tube assembly. The walls of the flushing channel and the drainage channel in the sinus treatment tube assembly are isolated from each other, which can ensure that the flushing fluid and the drainage fluid flow independently.

[0095] In addition, an extension tube 17 is intersected on the side wall of the first connecting member 15, and the extension tube 17 is connected to the drainage device. It is equivalent to dividing the nested tube body from the matching position of the first connecting member 15 and the second connecting member 16 into two independently arranged tube bodies, each of which is connected to a corresponding device.

[0096] In addition, the nested tube body parts can also be arranged as an independent tube body, and two independent channels, namely the flushing channel and the drainage channel, are constructed in the independent tube body.

[0097] The sinus treatment tube assembly provided in the embodiments of the present invention can be used in conjunction with a porous sponge. The porous sponge is wrapped around the outer surface of the sinus treatment tube assembly and extends into the sinus tract for absorption. The sinus treatment tube assembly can also be used in conjunction with a sealing membrane that can provide a closed negative pressure environment.

[0098] For example: according to the size and depth of the sinus, select a sinus treatment tube assembly of appropriate diameter and length, wrap the porous sponge on the outer surface of the sinus treatment tube assembly, penetrate the sealing membrane of the sinus treatment tube assembly and slowly insert it into the sinus. The insertion depth is determined according to the actual depth of the sinus.

[0099] After inserting the sinus treatment tube assembly, ensure it is properly positioned within the sinus tract, ensuring adequate drainage without compressing surrounding tissue. A medical film sealant is applied to the skin surrounding the sinus tract to secure the tube assembly in place and prevent displacement or dislodgment during use. Finally, an external drainage device (such as a drainage bag or pump) is connected for drainage.

[0100] Figure 8 This is a control block diagram of a sinus tract treatment device provided by an embodiment of the present invention.

[0101] See Figure 8 Embodiments of the present invention also provide a sinus treatment device. This device is a medical device used to treat sinuses caused by chronic infections, abscesses, or other diseases. It is designed to remove secretions, pus, or foreign matter from the affected area, sterilize, and promote wound healing. The sinus treatment device includes a drainage device and any of the sinus treatment tube assemblies. The tube body 11 of the sinus treatment tube assembly is connected to the drainage device.

[0102] The tube body 11 and the treatment end 12 of the sinus treatment tube assembly are both hollow hose-like structures. The treatment end 12 is inserted into the sinus tract, and the tube body 11 is exposed to the outside for connecting to a drainage device.

[0103] The drainage device can be a manual drainage bottle or drainage bag, or a negative pressure device for automatic drainage. When the drainage device is a drainage bottle or drainage bag, a connecting tube can be provided on the tube body 11, and the drainage bottle or drainage bag is connected to the connecting tube to collect fluid flowing out of the sinus tract. In addition, a check valve can be provided on the connecting tube to prevent external air from entering the sinus tract to reduce the risk of infection.

[0104] In addition, a fixing patch or other structure may be provided on the sinus tract treatment tube assembly to stabilize the position of the sinus tract treatment tube assembly and ensure that the sinus tract treatment tube assembly will not be easily displaced.

[0105] In some embodiments of the present invention, the sinus tract treatment device further includes a control module 40, a power regulation module 50, and a monitoring module 60. The control module 40 is electrically connected to the power module, the power regulation module 50, and the monitoring module 60, respectively. The monitoring module 60 comprises a sensor, etc., which is used to collect signals such as temperature, pressure, and current intensity, and feed the collected signals back to the control module 40. The control module 40 controls the discharge power, frequency, and duration of the power regulation module 50. This allows the discharge power (energy density), frequency, and duration of the plasma generator 20 to be adjusted according to the type and size of the sinus wound, providing targeted sterilization treatment for the affected area. This ensures stable and controllable plasma discharge, which can be flexibly adjusted according to the treatment depth and range, and can also provide precise treatment for different types of bacteria and wounds of varying depths.
