Embodiment 1

[0047] Such as Figure 1-4 As shown, the components and connection relationships of the bronchial thermoforming system in this embodiment are the same as described above. Here, only the above-mentioned uncertain specific parameters are defined in detail in order to understand the specific conditions of the bronchial thermoforming catheter involved in the present invention for performance comparison testing. The material of the radio frequency sub-needle is stainless steel. There are 4 working needles 2, image 3 Only two working needles 2 are shown for the cross-sectional view. The length of the working sub-needle 2 is 30±0.1mm, the width is 0.36mm, and the thickness is 0.1mm. The diameter of the radio frequency sub-needle 3 is 0.25±0.05 mm. The length of the working sub-needle 2 that is not covered by the film is 5.5±0.5mm. The wall thickness of the film is 0.01±0.005mm, and the film is a PET heat shrinkable tube. The working diameter range of the working end is 1.5-13mm....

Abstract

The invention provides a bronchial thermoplasty system which comprises a bronchial thermoplasty catheter and a bronchial thermoplasty radio frequency therapy instrument. The bronchial thermoplasty catheter comprises a working end, an outer sleeve tube and a handle. The working end comprises an end cap, working sub-needles, a support base and a radio frequency sub-needle. One end of each working sub-needle and one end of the radio frequency sub-needle are fixed to the end cap; the other end of each working sub-needle is fixed to the support base. The other end of the radio frequency sub-needle is connected with the handle after passing through the support base. The radio frequency sub-needle can slide on the support base. The two ends of each working sub-needle are electrically connected with the radio frequency sub-needle. The number of the working sub-needles is 3-6 and the radio frequency sub-needle is surrounded by the working sub-needles. The working sub-needles are made of nickel-titanium alloy and the radio frequency sub-needle is made of stainless steel or copper; the outer sleeve tube is a three-cavity tube. The bronchial thermoplasty system can display failure information in real time and has a large screen, and has the advantages of adjustable therapy time and adjustable power. The sub-needles are not liable to deform, and the adjustable bending angle of the catheter is larger; the working principle is simple and the operation is convenient.

Description

Technical field [0001] The invention relates to a medical device, in particular to a bronchial thermoforming system. Background technique [0002] Radio frequency refers to radio frequency, but it does not belong to the division of bands in radio communication. Because the radiation performance in such a frequency range is very low, it is seldom used in communication equipment. The main effect on living organisms is thermal effect. When the current frequency of the radio frequency is high to a certain value (> 100kHz), causing the movement of charged ions in the tissue, that is, frictional heat generation (60-100°C). The commonly used frequency of radiofrequency ablation equipment is 200-500kHz, and the output power is determined according to different ablation tissues, and for the bronchus, it is generally about 20W. [0003] Bronchial thermoplasty is an innovative asthma treatment technology. The end cap is introduced through a bronchoscope, and radiofrequency energy (or heat...
