Embodiment Construction
[0030] Such as figure 1 As shown, the ablation electrode in this embodiment includes a handle 11, a metal flexible tube 7, an electrode part, and a negative pressure channel for contracting and closing the tiny branches of the bronchi. Wherein, the handle 11 is provided with a through hole 13 through its interior, the front end of the through hole is at the same level as the front end of the handle, and the end of the through hole protrudes from the rear end of the handle to form a negative pressure suction pump interface. 14. In addition, a cable connector 12 is provided on the rear end surface of the handle for connecting with an external radio frequency electrode generator.
[0031] The end of the metal hose 7 is put into the through hole 13, so that the inner cavity 9 is docked with the through hole 13 and communicated with each other, thereby forming a negative pressure channel for shrinking and closing the tiny branch parts of the bronchi. The pressure channel communic...

The invention relates to an ablation electrode, in particular to an ablation electrode with the bronchus closing function, and aims to overcome the defect that an existing medical instrument can not effectively treat related symptoms of branch positions of the bronchus. The ablation electrode comprises a handle, a metal hose, an electrode part and a negative pressure channel. The negative pressure channel is used for shrinking and closing tiny branches of the bronchus. The electrode part comprises a radio frequency electrode and a temperature measuring resistor. The negative pressure channel is formed by connecting a cavity in the metal hose with a through hole inside the handle in a butt joint mode and communicating the cavity with the through hole. The negative pressure channel is communicated with an external negative pressure suction pump. The radio frequency electrode is matched with the negative pressure channel, in the ablation process, the radio frequency electrode is used for conducting thermal ablation on the wall of the bronchus, the external negative pressure suction pump is communicated with the negative pressure channel to generate negative pressure to shrink and close the tiny branches of the bronchus, and therefore the goal of effectively treating the related symptoms of the tiny branch positions of the bronchus is achieved, especially the bronchus fistula disease can be effectively treated.
Description
technical field [0001] The invention relates to an ablation electrode, in particular to an ablation electrode with bronchial closing function. Background technique [0002] A bronchopleural fistula is an abnormal channel formed between the bronchi and the pleura. Can be caused by a variety of reasons, such as tuberculous empyema, lobar pneumonia, lung abscess and postoperative infection. It is formed because the pus of chronic empyema corrodes the adjacent lung tissue and then penetrates the bronchi, or because the lung lesion directly invades the chest cavity or ruptures to form a fistula in the pleural cavity, or it is also caused by thoracentesis or surgical resection of the abscess infection. Pus can be coughed up from the bronchi, and in severe cases, a large amount of pus can be sucked into the bronchi, causing the patient to suffocate to death. When modern medicine treats the disease, after the complications are effectively controlled, the technique of injecting glu...
