非体外循环心内手术装置的设计与观察

Design and experimental application of a device for direct vision intracardiac operation without cardiopulmonary bypass

目的设计在非体外循环情况下进行心内直视手术的特殊装置,并对其实用性进行初步观察。方法根据心内直视手术特点,设计出非体外循环心内直视手术装置。利用该装置在5个游离猪心房间隔缺损模型上进行房间隔缺损修补手术,验证该装置的实用性,对手术效果进行观察。结果使用非体外循环心内直视手术装置可以完成房间隔缺损的直视手术。结论非体外循环心内直视手术装置对某些类型的心内直视手术较为理想,但临床效果尚需进一步观察。

Objective To design a device for direct vision intracardiac operation without cardiopulmonary bypass, and assess its applicability preliminarily. Methods The device was designed according to the clinical needs ofintracardiac operation and used in operations for repairing atrial septal defect in 5 ex vivo porcine heart models. The practical applicability of this device was thoroughly tested and the results of the operations were evaluated. Results and Conclusion Direct vision operation for repairing atrial septal defect was successfully performed using this device, which can be a well applicable in some intracardiac operations, but its clinical effects need further evaluation.
