Abstract

Objective To assess the feasibility of laser tissue welding for repair of facial nerve injury.

Methods In a prospective in vivo animal survival surgery model, rabbit facial nerve injury was followed by either standard suture neurorrhaphy or laser tissue welding using a diode laser (808 ± 1 nm) to weld biological solder. Rabbits were evaluated at 4, 8, 12, and 16 weeks by facial videography and electromyography. Histopathological analysis of the repair was performed at 4 and 16 weeks.

Results Videographic analysis demonstrated the laser tissue welding repair trended toward superior outcomes compared with suture neurorrhaphy at all 4 time points. Electrophysiological analysis demonstrated similar or better results, with statistically significant improvement at week 16 ( P  < .05). Histologic analysis demonstrated no difference in axon organization or extravasation between groups; however, the laser nerve repair created a greater initial inflammatory reaction. An analysis of operative time demonstrated significantly decreased time and ease of use for laser tissue welding.

12:21 San Benedetto, Scorzè plant, goes for Sacmi-RFST technology

One of the key features of this technology is its laser welding system; which allows strong sealing and hence outstanding high shrink applications of wrap-around labels directly from rollfed film. With RFST, labels are created and applied directly onto




LQ TwinWeld 3D | Laser Plastic Welding

With a robotic arm guided laser source, this system is designed for large parts and complex shapes. Did someone say car tail lights? The hybrid technology integrated into this systems sets it apart from the mix of other laser welders. Hybrid technology takes advantage of halogen lamps to provide polychromatic heating to the both welding partners. This added heat helps stabilize the plastic for the welding process as well as remove the need for an annealing process post-welding.
