Description
技术领域
本发明属于医疗器械技术领域,具体涉及一种载药可降解血管吻合器。
背景技术
在血管外科手术中,血管的缝合是必要操作,通常包括人工缝合吻合器吻合方式。使用人工缝合方式,时间通常在15分钟以上,不仅增加了患者的手术风险及成本,对医生也是较大的负担,同时人工缝合基于医生的手法、体力和熟练度,缝合质量参差不齐,对患者术后恢复带来一定的风险,严重会产生并发症。吻合器是替代传统手工缝合的设备,质量可靠,具有使用方便,尤其是缝合快速,操作简便和副作用少等优点。
目前的吻合器通常都是不可降解的吻合器,需要使用较为精密和体积大的吻合器或配套器械,术后留在体内的吻合器不可降解,会给患者带来长期的异物感,同时不可降解的吻合器长期留在体内,会在血管吻合出形成凸起,凹坑和斑痕等,会影响血流速度,给患者带来了长期的术后二次损伤风险和血栓风险。针对上述问题,本发明提出一种载药可降解血管吻合器。
发明内容
有鉴于此,本发明提供一种载药可降解血管吻合器,本发明通过可控的降解,减少了血管吻合器的滞留带来的风险,通过尖头铁芯能够保证穿刺部强度,保证吻合效果,同时铁基本身可降解,降解成分亚铁离子或铁离子有利于血红蛋白的形成,有利于血液运输;并能够通过载药促进血管细胞的生长分化,加速吻合处血管的吻合,减少斑痕的产生,最大程度减少组织损伤。
本发明的技术方案为:
一种载药可降解血管吻合器,其特征在于,包括对称设置的主部件,所述主部件包括夹持部、穿刺部、配合孔,所述穿刺部、配合孔分别对称排布于所述夹持部上;
所述相邻主部件的穿刺部与配合孔配合连接。
进一步地,所述穿刺部为尖头铁芯,保证穿刺部的强度;所述穿刺部的外部涂覆有药物层,可促进血管细胞的生长分化。
进一步地,所述夹持部为圆环状,中间提供血管通过的通道。
进一步地,所述夹持部包括易降解材料本体,可保证快速降解,避免游离到其他地方;所述本体的外层涂覆有铁基涂层,在作用时,减慢降解速率。
进一步地,所述配合孔是与尖头铁芯紧配的孔,可确保血管的夹闭,避免血液渗漏。
进一步地,所述尖头铁芯外侧设置有倒棱结构,确保血管不会滑脱,避免血液渗漏。
进一步地,所述尖头铁芯为含铜或铜的复合物的铁芯,铜或铜复合物可以促进血管细胞生长分化。
进一步地,所述主部件包含至少3根穿刺部。
进一步地,所述药物层为包括载体和促血管生长因子的混合物或促血管生长因子。
进一步地,所述载体为聚乳酸、羟基磷灰石、胶原等生物可降解材料的一种或几种的复合。
进一步地,所述夹持部的易降解本体材料为聚乳酸、羟基磷灰石、胶原等生物可降解材料的一种或几种的复合。
进一步地,所述促血管生长因子为前列腺素、丁酰甘油、透明质酸代谢物、金属铜的复合物、血管内皮生长因子以及 aFGF、bFGF、血管生成素、PD-ECGF、TGF、TNF等肽类血管生成因子等的一种或几种的复合。
本发明通过可控的降解,减少了血管吻合器的滞留带来的风险,通过尖头铁芯能够保证穿刺部强度,保证作用效果;并能够通过载药促进血管细胞的生长分化,加速吻合处血管的吻合,减少斑痕的产生,最大程度减少组织损伤。
本发明的有益效果在于:
1、降解,通过降解,减少了血管吻合器的滞留带来的风险,比如血栓,血管斑痕,血管搏动受限,血管生物力学的改变等;
2、可控降解,通过不同位置处采用不同的可降解材质,控制降解顺序和速率。完全降解顺序是药物层、尖头铁芯、夹持部。
3、本发明中所用尖头铁芯能够保证穿刺部强度,保证作用效果;
4、载药,通过载药促进血管细胞的生长分化,加速吻合处血管的吻合,减少斑痕的产生,最大程度减少组织损伤。
