经恶性肿瘤供血动脉内给药区域性化疗是治疗恶性实体肿瘤的有效方法[1]。它具有肿瘤局部药物浓度高。疗效显著，而全身副作用小等特点。随着医学高新技术的发展和先进医疗产品的开发，埋入式给药装置（药泵）的应用正取代传统的外引式插管法，成为恶性肿瘤区域性化疗的最新手段
Local administration of intra-arterial chemotherapy to malignant tumors is an effective method for the treatment of malignant solid tumors [1]. It has a high local drug concentration in the tumor. The effect is significant, and the systemic side effects are small. With the development of medical hi-tech and the development of advanced medical products, the application of a buried drug delivery device (pharmaceutical pump) is replacing the traditional external intubation method and has become the latest means of regional chemotherapy for malignant tumors.
