A new disposable microvascular double clip

A new disposable microvascular double clip made of polycarbonate has been designed. In order to investigate whether or not the clip causes vascular damage, experiments were conducted with scanning electron microscopy and light microscopy, using the common carotid arteries of Fischer rats. The study revealed that the new clip did not produce any damage to the arterial wall. The clip has also been used in 30 clinical cases, with generally good results. The new microvascular clip is economical, atraumatic to the vascular wall, and is always in the best condition, because of its disposability. The device is very useful for both laboratory and clinical microvascular surgery.
