无创消化道早癌磁锚定消融电极内镜系统的研制

Development of Non-invasive Endoscope System with Magnetic Anchored Ablation Electrode for Early Cancer of Digestive Tract

该文介绍了一种无创消化道早癌磁锚定消融电极内镜系统,包括磁锚定模块和消融电极模块。磁锚定模块 由外部引导磁体和内部靶磁体组成,由永磁材料钕铁硼制得;消融电极模块是基于现有的内窥镜(CMD- 90D型LED电子上消化道内窥镜)前端镜头罩改造而成。新内镜系统不仅包含原内镜的所有功能,同时引 入磁锚定使消融电极在治疗肿瘤的过程中能够精准定位且力度可控,避免发生胃穿孔的现象;引入陡脉冲 电场消融电极实现了无创治疗的目的。其临床应用将成为治疗消化道早癌的新方法。

This study introduces a non-invasive gastrointestinal early cancer magnetic anchor ablation electrode endoscopy system,including a magnetic anchor module and ablation electrode module.The magnetic anchoring module is composed of an external guide magnet and an internal magnet,made of permanent magnet material NdFeB;the ablation electrode module is based on the modification of the front end lens hood of the existing endoscope(CMD-90D LED electronic upper gastrointestinal endoscope).The new endoscope system not only includes all the functions of the original endoscope,but also introduces magnetic anchoring to enable the ablation electrode to be accurately positioned and controllable in the process of treating tumors,avoiding the phenomenon of gastric perforation;the introduction of steep pulse electric field ablation electrodes realizes the purpose of non-invasive treatment.Its clinical application will become a new method to treat early cancer of the digestive tract.
