Laser thermal forming treatment device for bronchial asthma

Abstract

The embodiment of the application discloses a laser thermal forming treatment device for bronchial asthma. In one specific implementation mode, the device comprises a laser light source, a catheter and a balloon arranged at one end of the catheter; an optical fiber is arranged in the catheter; a first end of the optical fiber serves as a laser input end, and is connected with the laser source; anda second end of the optical fiber is located in the balloon, serves as a laser output end and is used for making lasers emitted by the laser source to irradiate biological tissue. According to the implementation mode, the device has the advantages of high safety, high accuracy, high efficiency, low cost and the like in the process of realizing thermal ablation of the biological tissue through thethermal effect.

Description

technical field [0001] This application relates to the technical field of medical devices. More specifically, it relates to a laser-based laser thermoforming treatment device for bronchial asthma. Background technique [0002] At present, the treatment of some diseases requires the use of radio frequency thermoforming, taking the use of radio frequency thermoforming device bronchial asthma as an example: [0003] Asthma (Asthma) is a common chronic airway inflammatory disease characterized by reversible airflow limitation. According to statistics, there are 300 million people in the world who are sick, and more than 10 million people in China are sick. The etiology and pathogenesis of bronchial asthma are very complex and have not been fully elucidated so far. At present, patients with asthma often use steroids, β2 receptor agonists, leukotriene regulators, etc. to control their disease, but there are still 5%-10% of patients who cannot be relieved after conventional trea...

Problems solved by technology

[0007] First, radio frequency thermoplasty is a direct contact treatment. During the operation, the radio frequency electrode is in close contact with the inner wall of the human trachea after being energized and heated, which can easily damage the endotracheal membrane, leading to infection or scarring and easy formation Granulation, which poses additional risks and side effects to patients

[0008] Second, the use of radiofrequency thermoforming to treat severe asthma has a long treatment cycle, which virtually increases the patient's physical pain and economic burden

Each stage of treatment lasts for 30 minutes or more, the treatment cycle is too long and the efficiency is low

[0009] Third, radiofrequency thermoplasty is restricted by the structure of the inner wall of the airway, and the treatment area is limited

Radiofrequency thermoplasty is an energy coupling method that uses four electrode contacts to contact the inner wall of the trachea. In the case of severe contraction or irregular shape of the airway smooth muscle, the four electrodes may not be able to completely contact the inner wall of the airway, resulting in inability to Effective use of thermoplasty for surgical treatment

[0010] Fourth, the electrodes in radio frequency thermoforming are used as disposable medical consumables, and the price is relatively high
