技术介绍
众所周知,介入治疗(Interventionaltreatment),是介于外科、内科治疗之间的新兴治疗方法,包括血管内介入和非血管介入治疗。经过30多年的发展,现在已和外科、内科一道称为三大支柱性学科。简单的讲,介入治疗就是不开刀暴露病灶的情况下,在血管、皮肤上作直径几毫米的微小通道,或经人体原有的管道,在影像设备(血管造影机、透视机、CT、MR、B超)的引导下对病灶局部进行治疗的创伤最小的治疗的方法,介入治疗其特点是创伤小、简便、安全、有效、并发症少和明显缩短住院时间,介入治疗相对与内科治疗优点在于:药物可直接作用于病变部位,不仅可大大提高病变部位药物浓度,还可大大减少药物用量,减少药物副作用;它无需开刀暴露病灶,一般只需几毫米的皮肤切口,就可完成治疗,表皮损伤小、外表美观;大部分病人只要局部麻醉而非全身麻醉,从而降低了麻醉的危险性;损伤小、恢复快、效果满意,对身体正常器官的影响小;对于治疗难度大的恶性肿瘤,介入治疗能够尽量把药物局限在病变的部位,而减少对身体和其他器官的副作用,部分肿瘤在介入治疗后相当于外科切除,目前,现有技术的肿瘤内科用介入治疗针,就是普通的通用型注射穿刺针,主要包括有针柄和针体两大部分,由于针柄的整体形式较为短小,在为病人进行肿瘤介入治疗时不方便捏持,稍有不慎,很容易造成交叉感染,给医护人员增加了工作的难度,也在一定程度上增加了医护人员的劳动强度,针体通常较普通的注 ...
