[0026] Figures 1 to 2 The present invention provides a steam conveying structure 1000, which includes a steam conduit 100 and a reinforcing component 200. The steam conduit 100 can convey steam for ablation. The reinforcing component 200 is disposed on the side wall of the steam conduit 100.

[0027] In practical implementation, a reinforcing component 200 is introduced to address the problem of thermal expansion and deformation of the steam conduit 100 when delivering high-temperature steam, a problem inherent in existing technologies. The reinforcing component 200 is specifically installed on the side wall of the steam conduit 100, designed to enhance its structural stability and heat resistance, thereby effectively resisting the thermal expansion effect caused by high-temperature steam. Supported by the reinforcing component 200, the steam conduit 100 maintains its shape and dimensional stability, avoiding deformation due to thermal expansion, ensuring the effectiveness of steam delivery and the accuracy of treatment, and improving the reliability and safety of the thermal steam ablation technology.

[0028] According to one embodiment of the present invention, the reinforcing component 200 is disposed on the side wall of the steam duct 100.

[0029] In practical implementation, the reinforcing component 200 is not only installed on the side wall of the steam conduit 100, but also provides all-around reinforcement to the steam conduit 100 through an enclosing structure. This enclosing design allows the reinforcing component 200 to more evenly bear and distribute the thermal stress generated by the high-temperature steam, thereby more effectively preventing the steam conduit 100 from deforming due to thermal expansion. This layout of the reinforcing component 200 enhances the overall rigidity and heat resistance of the steam conduit 100, ensuring the continuity and stability of steam transportation, and further improving the performance and reliability of the steam transportation structure 1000 in high-temperature environments. Through this reinforcement method, the steam conduit 100 can maintain its structural integrity and transportation efficiency when transporting high-temperature steam, providing a more stable and efficient steam transportation solution for thermal steam ablation technology.

[0030] According to one embodiment of the present invention, the reinforcing component 200 is configured as a mesh structure.

[0031] In practical implementation, the mesh structure, through its open grid layout, effectively disperses the thermal stress generated in the steam conduit 100 during high-temperature steam transport, thereby reducing deformation caused by thermal expansion. Furthermore, the mesh structure design allows for better heat conduction and dissipation, helping to maintain a stable temperature for the steam conduit 100 and preventing localized overheating. Metal wires or high-performance fibers, used as materials for the reinforcing components 200, provide the necessary mechanical strength and heat resistance, ensuring the stability and durability of the steam transport structure 1000 under long-term high-temperature environments. This reinforcement component 200 not only enhances the structural integrity of the steam conduit 100 but also improves the reliability and safety of the entire steam transport system, providing a strong guarantee for the effective transport of high-temperature steam.

[0032] According to one embodiment of the present invention, the mesh structure is configured as a structural component made of metal wire or high-performance fiber.

[0033] In practical implementation, this design not only provides the necessary reinforcement but also, through structural components made of metal wire or high-performance fibers, possesses excellent heat resistance and high strength. The mesh structure of the metal wire or high-performance fibers uniformly disperses thermal stress, enhancing the stability of the steam conduit 100. Simultaneously, the high heat resistance of this material ensures reliability during high-temperature steam transport. Furthermore, the heat dissipation performance of the mesh structure helps control the temperature of the steam conduit 100, reducing thermal expansion effects, while its lightweight characteristics also help reduce the weight of the entire steam transport structure 1000, facilitating transport and operation. Combining these features, the mesh structure of the reinforcement component 200 not only improves the performance of the steam transport structure 1000 but also enhances its safety and service life, providing an efficient and stable solution for the transport of high-temperature steam.

[0034] According to one embodiment of the present invention, it further includes a reinforcing pipe 300, which is sleeved on the steam conduit 100, and a reinforcing component 200 is sandwiched between the steam conduit 100 and the reinforcing pipe 300.

[0035] In practice, the reinforcing tube 300 is fitted onto the steam conduit 100, forming a composite reinforcement system together with the reinforcing component 200. The reinforcing component 200 is sandwiched between the steam conduit 100 and the reinforcing tube 300; this design provides additional protection and support, enhancing the overall stability and heat resistance of the steam conduit 100. The presence of the reinforcing tube 300 not only provides physical protection for the steam conduit 100, preventing damage from external factors, but also works in conjunction with the mesh-structured reinforcing component 200 to form a more robust structure. This structural design allows the steam conduit 100 to operate more stably when delivering high-temperature steam, reducing the problems of decreased delivery efficiency or reduced treatment accuracy caused by thermal expansion and deformation. Furthermore, the combined use of the reinforcing tube 300 and the reinforcing component 200 helps improve the durability of the steam conduit 100, extending its service life and thus reducing maintenance costs and replacement frequency. This reinforcement method provides a more reliable and economical solution for the steam conveying structure 1000, meeting the high requirements for stability and safety during high-temperature steam conveying.

[0036] According to one embodiment of the present invention, the steam conduit 100 is a structural component made of medical-grade silicone.

[0037] In practical implementation, medical-grade silicone, due to its high-temperature resistance, can withstand the heat load generated during high-temperature steam delivery while maintaining chemical stability, avoiding adverse reactions with drugs or other chemicals. Furthermore, the flexibility of medical-grade silicone makes the steam conduit 100 easy to handle and shape, adapting to the needs of different treatment scenarios. Its high durability reduces conduit wear and maintenance costs, while its ease of cleaning and sterilization helps maintain hygiene standards for medical devices, reducing the risk of infection. Through this design, the steam delivery structure 1000 not only improves performance and safety during high-temperature steam delivery but also meets the stringent requirements of the medical field for high-precision and high-safety therapeutic devices.

[0038] According to one embodiment of the present invention, the reinforcing tube 300 is a structural component made of medical-grade silicone.

[0039] In practice, the reinforcing tube 300 and the steam conduit 100 are made of the same material, ensuring the consistency of the overall structure's chemical and physical properties, which helps improve the system's compatibility and stability. Medical-grade silicone can withstand high temperatures and is suitable for use in the steam delivery structure 1000, ensuring reliability during high-temperature steam delivery. The flexibility of silicone makes the reinforcing tube 300 easy to install and shape, while its durability helps reduce the frequency of maintenance and replacement. Silicone is easy to clean and sterilize, helping to maintain hygiene standards in the medical environment and reducing the risk of cross-infection.

[0040] According to one embodiment of the present invention, the reinforcing pipe 300 has a first end and a second end; the steam conveying structure 1000 further includes a first clamp 400 disposed at the first end for fixing the first end and the steam conveying pipe 600 of the steam ablation device.

[0041] In practical implementation, the reinforcing pipe 300 has clearly defined first and second ends. This design allows for more precise positioning and fixation of the steam conveying structure 1000. A first clamp 400 is located at the first end of the reinforcing pipe 300, its function being to secure the first end of the reinforcing pipe 300 to the steam conveying pipe 600 of the steam melting device, ensuring the stability and sealing of the entire steam conveying structure 1000. This design not only enhances the robustness of the connection between the steam conduit 100 and the steam melting device but also improves the sealing performance of the entire system, preventing steam leakage and ensuring the safety and efficiency of the conveying process. Furthermore, this end design and clamp fixing mechanism simplify the installation and maintenance process of the steam conveying structure 1000, improving its adaptability and versatility, and providing a more stable, safe, and easy-to-operate steam conveying solution for high-temperature steam melting technology.

[0042] According to one embodiment of the present invention, the steam conveying structure 1000 further includes a second clamp 500 disposed at the second end for fixing the second end and the steam generating pipe 700 of the steam ablation device.

[0043] For specific implementation details, working principle, and beneficial effects, please refer to the implementation method of the first clamp 400.

[0044] This utility model also provides a steam dissipation device, including a steam conveying structure 1000 as described in the above embodiments. The specific structure, working principle, and beneficial effects of the steam conveying structure 1000 are the same as those in the above embodiments, and will not be repeated here.

[0045] This utility model also provides a mesh-reinforced conduit (steam conveying structure 1000) and its preparation method.

[0046] The mesh-reinforced catheter consists of an inner silicone tube (steam conduit 100), a mesh reinforcement (reinforcing component 200), and an outer silicone tube (reinforcing tube 300). The inner silicone tube is made of medical-grade silicone to ensure biocompatibility and safety; the mesh reinforcement is woven from metal wires (such as stainless steel wire, copper alloy wire, aluminum alloy wire, etc.) or high-performance fiber filaments (such as ultra-high molecular weight polyethylene fiber filaments, aramid fiber filaments, carbon fiber, etc.) to provide necessary reinforcement and support; the outer silicone tube is also made of medical-grade silicone to protect the internal structure and provide an outer layer of protection.

[0047] The preparation method includes the following steps: First, the auxiliary core is extruded through the inner silicone tube mold to form the inner silicone tube, which then wraps around the auxiliary core. Next, a mesh reinforcement is braided and wrapped around the inner silicone tube. Then, the inner silicone tube wrapped with the mesh reinforcement is extruded through the outer silicone tube mold to form the outer silicone tube. During this process, a traction machine is used to pull the extruded inner and outer silicone tubes to ensure their uniformity and dimensional consistency, and they are fixed to the take-up reel by winding one turn with a traction wheel for subsequent processing and winding. In the preparation process, the inner silicone tube is prepared using a screw extruder, where blocky medical-grade silicone melts at a temperature of 135°C to 220°C, is extruded through the inner silicone tube mold, and undergoes desulfurization treatment in a vulcanizing chamber. The mesh reinforcement is braided onto the inner silicone tube by a braiding machine to form a cross-spiral mesh structure. The preparation of the outer silicone tube is similar to that of the inner silicone tube, except that it is extruded again onto the inner silicone tube wrapped with the mesh reinforcement.

[0048] When assembled into a steam ablation device, the mesh-reinforced conduit of this invention can effectively transport water vapor. Measurement data during steam transport shows that the conduit effectively prevents pipe deformation due to thermal expansion. Furthermore, the connection between the conduit and the steam generating component and steam delivery pipe passed sealing and pressure tests, with the pressure test reaching 650 kPa, demonstrating its excellent sealing performance and pressure resistance.
