[0002] In the medical steam ablation industry, in order to ensure product safety and traceability, EEPROM (or digital chip) is usually added to surgical instruments. There are currently two common practices: one is to install the EEPROM on the printed circuit board inside the surgical instrument and connect it to the ablation device body through a cable; the other is to solder the EEPROM to the pins of the connector. Although the first method is easy to implement, communication may be problematic in the case of long cables. Although the second method has high reliability, it has a high defect rate because the EEPROM is very sensitive to temperature during processing and is easily damaged. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Figure 1 to Figure 2 The steam ablation surgical instrument provided by the utility model is shown. As can be seen from the figure, the utility model provides a surgical instrument for steam ablation (or it can be called a steam ablation accessory), including an electrically erasable programmable read-only memory 100 (or it can be called a digital chip) and a high-temperature resistant protective structure 200; the high-temperature resistant protective structure 200 covers the electrically erasable programmable read-only memory 100.

[0023] During specific implementation, the surgical instrument is specially designed with a high temperature resistant protective structure 200 to protect the key component in the surgical instrument, the electrically erasable programmable read-only memory 100 (i.e., the digital chip). This high temperature resistant protective structure 200 can effectively solve the problem in the prior art that the digital chip is easily damaged during processing due to its lack of high temperature resistance. By covering the digital chip with the high temperature resistant protective structure 200, the safety and function of the chip can be ensured to be undamaged even in the high temperature and high pressure surgical instrument processing and use environment. In this way, not only the reliability and durability of the surgical instrument are improved, but also the safety and traceability of the product are guaranteed, thereby improving the performance and service life of the entire steam ablation surgical instrument.

[0024] In this embodiment, the surgical instrument may be a handle or a scalpel.

[0025] According to one embodiment of the present invention, the high temperature protection structure 200 includes a memory protection component and a high temperature resistant component; the memory protection component covers the electrically erasable programmable read-only memory 100; and the high temperature resistant component covers the memory protection component.

[0026] In specific implementation, the memory protection component directly covers the electrically erasable programmable read-only memory 100 to play a preliminary protective role, while the high-temperature resistant component further covers the memory protection component to provide additional high-temperature protection. This double-layer protection mechanism not only ensures the stability and safety of the digital chip in the face of high-temperature processing environments, but also enhances the overall durability and reliability of surgical instruments through specially designed high-temperature resistant components. This design allows surgical instruments to maintain performance even under extreme working conditions, reducing the cost of repair or replacement due to chip damage, while also ensuring safety and efficiency during surgery.

[0027] According to an embodiment of the present utility model, the memory protection component is a structural member made of curing glue.

[0028] In specific implementation, the design of this curing glue structure can not only provide necessary physical protection for the electrically erasable programmable read-only memory 100 (digital chip) to prevent it from being damaged during the manufacture and use of the surgical instrument, but the curing glue material itself may also have certain high temperature resistance characteristics, thereby resisting the adverse effects of high temperature environment on the chip to a certain extent. By using curing glue as a memory protection component, surgical instrument manufacturers can enhance the durability and reliability of key electronic components in the instrument in a relatively simple and cost-effective way, ensuring the stability of instrument performance and the safety of surgery during surgery.

[0029] According to one embodiment of the present invention, the curing adhesive is a UV curing adhesive.

[0030] In the specific implementation, ultraviolet light curing glue (UV glue) is used as a memory protection component. This curing glue can not only quickly cure under ultraviolet light to form a hard and high-temperature resistant protective layer, but also has good bonding strength and chemical stability, effectively resisting the invasion of high temperature and corrosive substances. Using UV glue as a protective material not only improves the production efficiency of surgical instruments, because its rapid curing characteristics are suitable for the needs of rapid production, but also enhances the durability and reliability of the instrument, ensuring the stability and safety of the digital chip during the operation, thereby improving the performance of the entire steam ablation surgical instrument.

[0031] According to one embodiment of the utility model, the high temperature resistant component is a high temperature resistant tape, and at least one layer of high temperature resistant tape is wound around the storage protection component.

[0032] In a specific implementation, at least one layer of high temperature resistant tape is wrapped around the memory protection component made of curing glue. This high temperature resistant tape usually has excellent heat resistance and can withstand the high temperature environment that may be encountered during surgery, thereby providing an additional layer of protection for the memory. Such a design not only enhances the durability and reliability of the surgical instrument, but also ensures the stability of the digital chip and the integrity of the data under high temperature conditions. By wrapping the high temperature resistant tape, the memory protection component is further reinforced, so that the entire surgical instrument can maintain efficient and safe operation even in the face of extreme conditions, thereby improving the success rate of the operation and the service life of the instrument.

[0033] According to one embodiment of the present invention, the high temperature resistant tape is a polyimide tape.

[0034] In specific implementation, polyimide is selected for its excellent heat resistance, mechanical properties and chemical stability. Using PI tape as a high temperature resistant component, at least one layer is wrapped around the memory protection component to provide an additional protective barrier for the electrically erasable programmable read-only memory 100. This protection not only ensures the stability of the chip when facing the high temperature challenges that may be encountered during the processing and use of surgical instruments, but also improves the durability and reliability of the overall instrument. The application of PI tape further enhances the performance of surgical instruments in high temperature environments, ensures the safety and efficiency of surgery, and also allows the instrument to maintain a high performance standard during long-term use.

[0035] According to one embodiment of the utility model, the high temperature resistant tape is multi-layered, and the multi-layer polyimide tape is wound on the high temperature resistant component.

[0036] In specific implementation, by increasing the number of layers of tape, the protection capability of the memory can be significantly improved, ensuring that the digital chip can still work safely and stably when facing higher temperatures and more complex working environments. The use of multi-layer polyimide tape not only provides a stronger thermal insulation effect, but also enhances the mechanical strength of the overall structure, making the surgical instrument more durable and extending its service life, while also improving reliability during surgery. This multi-layer winding design optimizes the high temperature resistance of surgical instruments, allowing the instruments to better adapt to the medical environment of high-temperature steam ablation, ensuring the smooth progress of the operation and medical safety.

[0037] According to an embodiment of the present invention, it further comprises an anti-disassembly plastic part 300, and the anti-disassembly plastic part 300 covers the high temperature resistant component.

[0038] In specific implementation, this anti-disassembly plastic part 300 covers the high-temperature resistant component, providing further protection for the memory protection component that has been reinforced by multiple layers of polyimide tape. The design of the anti-disassembly plastic part 300 not only enhances the overall durability of the surgical instrument, but also has the function of preventing unauthorized disassembly, because disassembly will cause damage to the plastic parts, and the plastic parts can be injection molded to ensure the integrity and safety of the instrument. By adding this layer of anti-disassembly plastic part 300, the protection of the instrument during transportation, storage and use is enhanced, which helps prevent accidental damage or unauthorized tampering. This design is essential to maintaining the functionality and reliability of surgical instruments, especially in high-temperature and high-pressure steam ablation surgical environments. In addition, the presence of the anti-disassembly plastic part 300 may also help meet regulatory requirements for certain medical devices to ensure patient safety and surgical success rates. Therefore, the technical effect of this requirement is to improve the safety, integrity and durability of surgical instruments, while ensuring the stability and reliability of the instruments in medical procedures.

[0039] The utility model also provides a steam ablation device, comprising: an ablation device body; a surgical instrument for steam ablation as in the above embodiment, connected to the ablation device body. The specific structure, working principle and beneficial effects of the surgical instrument for steam ablation are the same as those in the above embodiment, and will not be repeated here.

[0040] The utility model also provides an innovative method for manufacturing steam ablation accessories. This method involves an aviation connector, a special chip, and two key materials: UV curing glue and polyimide tape. The specific steps are as follows:

[0041] 1. Soldering the chip: First, solder the DS2431+ chip to the aviation connector, which is the interface between the steam ablation accessory and the ablation device body.

[0042] 2. Apply UV curing glue: Then, apply a layer of UV curing glue evenly on the outside of the chip. This step can be done manually or with a professional glue dispenser to ensure the uniformity and thickness of the glue layer. In order to ensure that the chip is fully protected, it is recommended that the thickness of the glue layer be at least 2 mm.

[0043] 3. Curing the UV light curing glue: Next, use a UV light source to irradiate the UV light curing glue for a period of time until the glue is completely cured to form a hard protective layer.

[0044] 4. Wrap polyimide tape: Wrap polyimide tape on the cured UV-curable adhesive, making sure the tape is wide enough to cover the entire chip and its pins. Depending on the actual size of the connector and the temperature during molding, it is recommended to wrap 2 to 4 layers of polyimide tape to balance protection and accessory size.

[0045] 5. Injection molding: Finally, complete the welding work of other pins and put the component into the machine for injection molding to complete the manufacturing of the accessory.

[0046] Through this method, high-reliability chip implantation can be achieved at a lower cost and smaller volume, ensuring that the chip of the steam ablation accessory will not be damaged in the high-temperature and high-pressure production environment, thereby improving the durability and reliability of the product.

[0047] Understandably, this method cleverly utilizes two common and readily available materials – polyimide tape and UV-curing adhesive – to protect the digital chip in the accessory and ensure that it is not damaged by the high temperatures and pressures during the production process.

[0048] First, polyimide tape has become an ideal thermal insulation material due to its excellent heat resistance (capable of withstanding temperatures exceeding 260°C) and extremely low thermal conductivity. Moreover, polyimide tape is easy to purchase and has a low cost. Its thin design allows it to achieve excellent thermal insulation without increasing the volume of the product.

[0049] Secondly, UV curing adhesive, with its high hardness and good elasticity after curing, has become an ideal buffer material between the chip and the connector housing. There are many types of UV curing adhesives, and you can choose the right type according to different needs. It can also usually withstand high temperatures, which makes it very suitable for reducing the pressure on the chip during the molding process.

[0050] Combining the advantages of these two materials, this patent utility model provides a new method for preparing digital chips implanted in steam ablation accessories. This method can not only effectively protect the chip from damage during mechanical processing, but also help improve product reliability and production efficiency. It is a cost-effective and practical solution.
