Problems solved by technology
In the past ten years, inhaled anti-inflammatory drugs (including glucocorticoids) and long-acting β-receptor agonists have been the main drugs for the treatment of asthma, but the effect of using these drugs in many critically ill patients is not obvious
In addition, because the above two drugs contain hormones, long-term use will also cause adverse effects on the patient's body.

Embodiment Construction
[0045] like Figure 1 to Figure 7As shown, the radio frequency antenna for treating asthma provided by the present invention is composed of a handle 1, a sleeve 2, a catheter 3, a mesh radio frequency electrode and a front end fixing head 7. One end of the handle 1 is arranged in the sleeve 2, and the catheter 3 One end of the tube is sequentially arranged in the casing 2 and the handle 1, an insulating layer is also provided on the outer wall surface of the catheter 3, and the front end fixing head 7 is installed on the front end of the mesh radio frequency electrode. An insulating layer is provided on the outer surface of the conduit 3 . Wherein, the mesh radio frequency electrode is memory alloy electrode mesh 4 . In the conduit 3, a temperature-measuring wire 17 and a cooling chamber 15 are arranged, and the cooling chamber 15 is connected to one end of the memory alloy electrode network 4. The temperature-measuring wire 17 runs through the inside of the cooling chamber 1...

The invention relates to a radio-frequency antenna for treating asthma. One end of a grip is arranged in a sleeve; one end of a guide tube is sequentially arranged in the sleeve and the grip; a front end fixation head is installed on one end of a mesh radio-frequency electrode; the mesh radio-frequency electrode is a memory alloy electrode mesh; a temperature measurement wire and a cooling cavityare arranged in the guide tube; the cooling cavity is connected with the memory alloy electrode mesh; the temperature measurement wire penetrates through the inside of the cooling cavity and is connected with the memory alloy electrode mesh; one end of the memory alloy electrode mesh is provided with a temperature measurement resistor; and the unfolding diameter of the memory alloy electrode meshoutside the guide tube is regulated by shifting the grip in the sleeve. The mesh radio-frequency electrode made of memory alloy, which is sufficiently in contact with the tracheal wall, is used for treating asthma, and controlled therapeutic heat is transferred to the tracheal wall to reduce the contractility and high responsivity of the airway smooth muscles, thereby achieving the goal of reducing the quantity of airway smooth muscles and further relieving and curing asthma symptoms.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to an asthma treatment equipment, especially a radio frequency antenna for treating asthma. Background technique [0002] Asthma is a disease with recurrent wheezing, chest tightness, dyspnea, and coughing as the main symptoms. It is generally divided into chronic asthma and acute asthma. Among them, chronic asthma is characterized by airway remodeling, including airway wall thickening, mucus glands and goblet cells, vascular hyperplasia, and most importantly, airway smooth muscle hyperplasia. Acute asthma has a variety of trigger factors, and generally manifests as airway narrowing caused by airway smooth muscle contraction. In addition to this mechanical effect, airway smooth muscle also participates in airway inflammatory responses through three mechanisms: secretion of cytokines, changes in tissue matrix components, and binding of inflammatory cells. The contraction of airway ...
