Microwave device for non-contact endobronchial therapy

Abstract

The invention relates to a noncontact bronchus intracavitary therapy microwave device, which comprises a microwave security protection probe, a control handle and a microwave controller, wherein the microwave security protection probe consists of a guide tube, metal wires and a microwave probe; a plurality of metal wires, a microwave probe and a microwave lead are arranged in the guide tube; the metal wires are bent elastic pieces; the end parts of the metal wires are connected together; the microwave probe is positioned in the middle of the plurality of metal wires, and is connected with the microwave lead; the metal wires, the microwave probe and the microwave lead can move in the guide tube along an axial direction; the guide tube is connected to a guide tube fixer; the metal wires pass through the guide tube fixer and a handle fixing rod, and are connected to a sliding handle; and the microwave lead is connected with a microwave controller connecting end on the sliding handle. Due to the adoption of a noncontact bronchus microwave probe disclosed by the invention, therapy can be performed specific to tumors on bronchial walls and outside lumens, pain of patients is reduced, and the surgery success probability is increased.

Description

technical field [0001] The invention belongs to the technical field of medical equipment manufacturing, in particular to a non-contact microwave device for bronchial cavity treatment. Background technique [0002] Microwave, as a treatment method, has been widely used in various fields, and it has been developed rapidly for the treatment of airway diseases through flexible bronchoscope. [0003] The treatment of airway diseases (especially lung cancer) is a comprehensive treatment, including surgery, radiotherapy, chemotherapy and so on. Commonly used treatment methods for diseases confined to the central airway include laser (Nd:YAG, argon knife, CO2), photodynamic therapy (PDT), intracavitary radiotherapy, microwaves, cryotherapy, and high-frequency electrotherapy. Microwave radiation is used in the treatment of central lung cancer, and also in the treatment of airway stenosis. It has achieved good results in relieving bronchial obstruction, improving symptoms and prolong...

AI Technical Summary

Problems solved by technology

[0004] At present, the bronchial microwave probe directly contacts the tumor, and the tumor in the bronchial cavity is heated and cauterized, but the tumor on the bronchial wall and outside the lumen cannot be treated. However, when radio frequency is used to treat bronchial asthma, the safety structure outside the probe can effectively prevent the direct contact between the probe and the tube wall. Contact, but so far there is no security probe for microwave treatment of bronchial wall and extraluminal tumors
