摘要
目的根据磁锚定原理设计用于辅助内镜下胃空肠吻合的相关器械。方法分析目前内镜下胃空肠吻合操作中存在的技术瓶颈,结合研究者前期在磁外科方面的研究积累,设计了消化道腔内磁锚定技术辅助胃空肠吻合相关器械。结果提出了电磁-液磁耦合胃肠锚定穿刺方案,内镜下通过在胃内放置电磁装置,在空肠内通过导管输送液磁,电磁装置通电工作后可产生磁场力吸附空肠内液磁,使胃壁和肠壁紧密贴附,为内镜下建立胃空肠穿刺提供靶向性,大大提高了穿刺的安全性。体外模拟结果显示磁力能够满足实际操作需要。结论电磁-液磁耦合消化道腔内磁锚定技术能够提高内镜下胃空肠穿刺的靶向性和安全性,能有效解决内镜下胃空肠吻合的技术瓶颈。
Objective According to the principle of magnetic anchor technique, the related instruments were designed to assist gastrojejunostomy under endoscope. Methods This paper analyzed the technical bottleneck existing in endoscopic gastrojejunostomy, and put forward an endo-luminal magnetic anchor assisted gastrojejunostomy design. Results An electromagnetic and liquid-magnetic coupling gastrointestinal anchoring puncture scheme was proposed. The electromagnetic device was put in the stomach under endoscope, and the liquid magnetic field was transported through the catheter in the jejunum. The magnetic field force could be adsorbed after the electromagnetic device was electrified. The gastric wall and intestinal wall were closely attached, which provided a target for the establishment of gastrojejunal puncture under the endoscope, and greatly improved the safety of the puncture. In vitro simulation results showed that the magnetic force could meet the practical needs. Conclusion Electromagnetic-liquid magnetic coupling endo-luminal anchoring technique can improve the targeting and safety of endoscopic gastrojejunostomy and solve the technical bottleneck of endoscopic gastrojejunostomy.
