The purpose of this study is to evaluate the biomechanical performance of laser-drilled and channel needle swages. The laser-drilled swages have a more uniform circumference that encounters lower drag forces than the channel needle swages. In addition, the length of the laser-drilled hole is shorter than that of the channel needles, allowing the physician to grasp the laser-drilled needle close (3 mm) to the needle end without deformation. These benefits of laser-drilled swages indicate that they should replace all channel needles.
本研究的目的是评估激光打孔和通道式针型锻件的生物力学性能。激光打孔的锻件圆周更均匀，与通道式针型锻件相比，其受到的阻力更小。此外，激光打孔的长度比通道式针短，这使得医生能够在距针端很近（3毫米）的位置握持激光打孔针而不会使其变形。激光打孔锻件的这些优点表明它们应该取代所有的通道式针。
