RESUMEN
@#Nowadays, the development of the medical instrument industry makes rapid changes in clinical practice. Hybridization of latest technology is playing an increasingly important role in the diagnosis and treatment of disease. Especially, the trend of the integration of three-channel hybrid technology in diagnosis and treatment of early lung cancer has become increasingly obvious. This paper will focus on the technical advance of the three-channel multi- mirror robot and its application in the diagnosis and treatment of early lung cancer.
RESUMEN
Objective To compare the X-ray radiation dose from atrial fibrillation (AF) ablation guided by magnetic navigation system (MNS) and manual procedure (CON).Methods 94 AF patients were randomly divided into MNS group (34 cases) and CON group(60 cases).The dose area product (DAP),cumulative radiation dose (CD),fluoroscopy time of patients,the X-ray exposure time and dose of operators were recorded and analyzed.Results The results from the patients in MNS group and CON group were CD values (0.54 ±0.45) and (1.61 ±0.89) Gy (t =2.44,P ＜0.05),DAP values (46.86 ±27.09) and (139.71 ±76.69) Gy·cm2(t =3.89,P ＜0.05) and fluoroscopy time (15.60 ±7.52) and (39.50 ± 8.82) min (t =1.96,P ＜ 0.05),respectively.The X-ray exposure dose in both groups were (22.68 ± 6.87) and (62.74 ± 20.92) μSv (t =2.02,P ＜ 0.05) for operation doctor (19.38 ± 5.64) and (49.42 ± 10.67) μ Sv (t =3.58,P ＜ 0.05) for operation assistant and (18.98 ± 4.99) and (47.77 ± 13.65) μ Sv (t =3.17,P ＜ 0.05) for nurse,respectively.The X-ray exposure time experienced in both groups were (11.48 ±7.59) and (30.50 ±14.82) min (t =2.75,P ＜0.05) for operation doctor,(8.96 ±5.88) and (24.49 ±9.09) min (t =4.20,P ＜0.05) for operation assistant and (8.33 ±6.35) and (22.99 ± 13.36) min(t =2.76,P ＜ 0.05) for nurse,respectively.Conclusions Compared with manual procedure,the MNS applied in AF ablation has the potential to decrease X-ray exposure dose.
