摘要
目的 :研制一种拉索式血管分流装置,用于处理四肢血管离断并缺损时肢体远端的临时缺血。方法 :设计一种新型拉索式单向绞索扣,装置内卡齿间距0.5 mm,有止退功能,只能越扎越紧,更方便快捷并牢固固定血管与分流管。用拉索式绞索扣合并硅胶管连接缺损血管两端,通过血管爆破压、抗拉生物力学试验比较其与常规缝线结扎合并硅胶管连接方法的效果差异。结果:经拉索式绞索血管分流装置固定的血管在血管爆破压、抗拉生物力学方面均优于传统缝线并硅胶管分流装置,差异有显著统计学意义(P<0.05)。结论:该拉索式绞索血管分流装置可简单有效地恢复离断并缺损的四肢血管,快速恢复远端肢体缺血,为后送至有条件的医院进行血管移植创造有利条件。
Objective To develop an interlocking-style vascular shunt device for the treatment of distal limb ischemia resulting from vascular disconnection and defect. Methods A one-way interlocking buckle was designed with the space between the clamping teeth being 0.5 mm, which prevented the device from moving backwards and fixed the vessel and shunt tube conveniently. The interlocking buckle combined with silicone tube was used to connect the two ends of the defected vessel, which was compared with conventional method by suture ligation and silicone tube by the tests on vessel bursting pressure and tensile biomechanics. Results The vessel repaired with the developed device behaved better than that by the conventional method in the tests on vessel bursting pressure and tensile biomechanics(P〈0.05). Conclusion The vascular shunt device can be used for the treatment of distal limb ischemia resulting from vascular disconnection and defect, and thus facilitates the vascular graft in rear hospital after evacuation.
