[0002] Balloon devices are widely used in the medical field for applications such as vasodilation, occlusion, hemostasis, and tissue ablation. Traditional heated balloons suffer from slow heating rates, poor temperature uniformity, and high energy consumption, making them unsuitable for the rapid and precise clinical needs.

[0008] A high-frequency power supply, wherein the high-frequency power supply is connected to the heating wire via a wire arranged inside the conduit;

[0009] A temperature sensor is disposed within the balloon body;

[0010] The temperature control module is connected to the temperature sensor via a signal line laid inside the conduit, and is also connected to the high-frequency power supply.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] The rapid heating balloon device proposed in this application improves the temperature uniformity after heating to a certain extent by spirally winding the heating wire inside the balloon body.

[0029] See attached document Figure 1This application provides a rapid heating balloon device, including a conduit 1, a heating wire 3, a balloon body 2, a high-frequency power supply 5, a temperature sensor 4, and a temperature control module 6. The balloon body 2 is located at the distal end of the conduit 1, and a first interface 13 and a second interface 14 are located at the proximal end of the conduit 1. The conventional second interface 14 is used to connect an infusion pump 15 to infuse liquid into the balloon body 2, thereby inflating the balloon body 2. The heating wire 3 is spirally wound around the balloon body 2 along its axial direction. The spirally wound heating wire 3 can, to a certain extent, make the liquid temperature inside the balloon body 2 more uniform. The heating wire 3 is connected to a wire 7, which extends along the conduit 1 to the first interface 13. The high-frequency power supply 5 is externally connected to the first interface 13 to energize and heat the heating wire 3. Temperature sensor 4 is also located inside balloon body 2, and is connected to signal line 8. Signal line 8 extends along catheter 1 to first interface 13, where temperature control module 6 is externally connected. Temperature control module 6 is also connected to high-frequency power supply 5. Temperature control module has built-in PID controller, which adjusts the heating power of high-frequency power supply 5 through feedback signal from temperature sensor 4.

[0030] In this embodiment, the balloon body 2 is made of flexible medical-grade silicone material, with a diameter of 2.0 cm and a length of 3-5 cm, forming a sealed cavity inside for injecting liquid media (such as water, saline, or contrast agents). The heating wire 3 is a 1 mm diameter medical-grade metal wire (such as nickel-titanium alloy, stainless steel, or carbon fiber composite material) with a length of approximately 1.2 meters. The high-frequency power supply 5 is selected from Beijing Yanxintong Technology HAC250-490E, and the temperature control module 6 is selected from Xinsheng Automation ZTCSV400. The temperature sensor 4 is a linear sensor, such as a thermocouple temperature sensor or a thermistor sensor, with a built-in temperature measurement module. The temperature control module 6 can be a commonly used thermocouple or thermistor; the thermocouple can be, for example, a T-type or K-type. Of course, the above model selection is only an example and is not limited.

[0031] Of course, in a preferred embodiment, in order to effectively deliver the balloon body 2 to the affected area, such as... Figure 2 As shown, a guidewire 9 is disposed inside the catheter 1, with the guidewire 9 alternating with the catheter 1 to facilitate the entry of liquid from the catheter 1 into the balloon body 2. The temperature sensor 4 is fixed to the outside of the guidewire 9 by a hook 17. One end of the guidewire 9 is fused to the distal end of the catheter 1, and the other end of the guidewire 9 extends to the first interface 13. The guidewire 9 is provided with wiring holes 10 for laying the wires 7 and signal lines 8, respectively, to prevent the wires from tangling and knotting together.

[0032] Since guidewire 9 is used to deliver the balloon body 2, it typically possesses a certain degree of flexibility to ensure good passage during delivery. This means that during balloon inflation, guidewire 9, connected to the distal end of catheter 1, may bend due to the outward stretching of the balloon. To reduce the occurrence of this, such as... Figure 2 As shown, the heating wire 3 includes a spiral section 301 and a spiral section 302, which are integrally formed. The spiral section 301 and the spiral section 302 are coaxially arranged, with the spiral section 301 located inside the spiral section 302. The spiral section 301 is coiled against the outer wall of the guide wire 9, thus forming an integral unit with the guide wire 9, increasing the support of the guide wire 9 and reducing the likelihood of bending due to tension. Simultaneously, the outer diameter of the spiral section 302 is half the inner diameter of the balloon body 2, thus maintaining a suitable position for the spiral section 302 and contributing to the uniformity of heating to a certain extent.

[0033] Furthermore, in one embodiment, to prevent the solder joints of the wires 7 and 8 with the heating wire 3 and temperature sensor 4 from detaching during use, such as... Figure 3 As shown, the wiring hole 10 includes an enlarged portion 101 and a constricted portion 102. The inner diameter of the enlarged portion 101 is larger than the inner diameter of the constricted portion 102. Both the wire 7 and the signal line 8 include a straight extension portion 12 and a bent portion 11. The bent portion 11 is located within the enlarged portion 101, and the straight extension portion 12 is located within the constricted portion 102. In actual manufacturing, the copper core used as the wire 7 and signal line 8 is bent into an S-shape under heating, and then quenched and shaped. Thus, the bent portion 11 has spring-like properties, capable of elongating under tension and rebounding after the external force is removed. The bent portion 11 provides a certain amount of flexibility for the movement of the wire 7 and signal line 8, preventing them from breaking or falling off from the temperature sensor 4 and heating wire 3 due to pulling or contact with the balloon during use. At the same time, the side of the enlarged portion 101 extending towards the proximal end of the conduit 1 is sealed with sealant 16 to prevent liquid leakage.

[0034] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
