作为改进，所述的剪把的一个外壁上设有齿部，齿部用于增大摩擦力，另一个剪把铰接有一个固定杆，所述的固定杆的另一头可以卡在齿部中。
作为改进，所述的固定杆中间为一个槽道，槽道顶部壁卡在齿部中。
作为改进，在固定杆和剪把的铰接轴处连接有弹簧，所述的弹簧给固定杆一个逆时针转动的力，限制其顺时针转动。
作为改进，固定杆的端部设有一个拨槽，所述的拨槽用于拇指转动固定杆顺时针方向转动。
作为改进，所述的剪头表面设有聚合物抗菌涂层，所述的抗菌涂层的厚度为0.01mm-1mm，所述的的聚合物涂层是一种聚碳酸酯多单体接枝聚合物,所述的接枝单体包括二甲基(2-吡啶基)乙烯基硅烷和丙烯腈单体。
作为改进，所述的聚合物及接枝单体原料重量份如下：聚碳酸酯100份，二甲基(2-吡啶基)乙烯基硅烷5-20份，丙烯腈单体5-20份。
作为改进，所述的聚合物涂层的制备方法如下：
步骤A：将不饱和硅烷、丙烯腈均匀混合；
步骤B: 将聚碳酸酯在流变仪中熔融；
步骤C：步骤A后的混合物以及引发剂加入到流变仪中，反应5 min -10min。
作为改进，所述的引发剂选自过氧化苯甲酰、过氧化月桂酰、异丙苯过氧化氢、叔丁基过氧化氢、过氧化二异丙苯。
作为改进，所述的引发剂为过氧化苯甲酰和过氧化二异丙苯的混合物，摩尔比为1:（0.7-1.5）。
作为改进，所述步骤B的熔融时间为1-5min。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
本发明的血管剪能够一个剪把对应多个不同型号的剪头，并且相互的紧固性好，本发明的固定杆能够对张开的剪头进行有效固定，减轻了人手指固定的疲劳感，同时抗菌涂层能够减少表面细菌的残留量，减少伤病患者的感染。

为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
具体实施例1：如图1-4所示，一种紧固血管剪，包括剪把1和剪头2，所述的剪把1和剪头2为可拆卸的连接，所述的可拆卸的连接剪把末端的凹部101、剪头末端的凸部201，所述的凸部深入到凹部中，所述的凸部带有一定的弹性结构，所述的凹部的外壁螺纹连接有固定管3。所述的剪把的一个外壁上设有齿部102，齿部用于增大摩擦力，另一个剪把铰接有一个固定杆103，所述的固定杆的另一头可以卡在齿部102中。所述的固定杆中间为一个槽道，槽道顶部壁卡在齿部中。在固定杆和剪把的铰接轴处连接有弹簧，所述的弹簧给固定杆一个逆时针转动的力，限制其顺时针转动。固定杆的端部设有一个拨槽1031，所述的拨槽用于拇指转动固定杆顺时针方向转动。
具体实施例1：一种紧固血管剪，和实施例1的区别在于，所述的剪头表面设有一种聚碳酸酯多单体接枝聚合物,其特征在于，所述的接枝单体包括含有二甲基(2-吡啶基)乙烯基硅烷和丙烯腈单体。
所述的聚合物及接枝单体原料重量份如下：聚碳酸酯100份，二甲基(2-吡啶基)乙烯基硅烷单体5份，丙烯腈单体20份。
聚合物涂层的制备方法如下：
步骤A：将不饱和硅烷、丙烯腈均匀混合；
步骤B: 将聚碳酸酯在流变仪中熔融，熔融时间为5min；
