A new atraumatic smooth needle holder jaw with rounded edges that does not damage synthetic monofilament sutures is described herein. These rounded edges were created by mechanical filing of the sharp edges of smooth needle jaws. Compression of the monofilament suture between the needle holder jaw with sharp edges reduces the suture breaking strength compared with that of control sutures. A quality control method has been devised to detect the potentially damaging sharp edges of smooth needle jaws that can be easily implemented by needle holder manufacturers.
本文介绍了一种新型无创平滑持针钳钳口，其边缘呈圆形，不会损坏合成单丝缝线。这些圆形边缘是通过对平滑持针钳钳口的尖锐边缘进行机械锉削而形成的。与对照缝线相比，带有尖锐边缘的持针钳钳口对单丝缝线的挤压会降低缝线的断裂强度。已经设计出一种质量控制方法，用于检测平滑持针钳钳口可能造成损伤的尖锐边缘，持针钳制造商可以轻松实施该方法。
