    Feature Of The Week 01/18/15: An Integrated Optical Coherence Tomography-Gas Nozzle System for Surgical Laser Ablation Applications

    Gas assisted laser machining of materials is a common practice in the manufacturing industry. Advantages in using gas assistance include reducing the likelihood of flare-ups in flammable materials and clearing away ablated material in the cutting path. Current surgical procedures and research do not take advantage of this and in the case for resecting osseous tissue, gas assisted ablation can help minimize charring and clear away debris from the surgical site. In the context of neurosurgery, the objective is to cut through osseous tissue without damaging the underlying neural structures. Different inert gas flow rates used in laser machining could cause deformations in compliant materials. Complications may arise during surgical procedures if the dura and spinal cord are damaged by these deformations. We present preliminary spinal deformation findings for various gas flow rates by using optical coherence tomography to measure the depression depth at the site of gas delivery.

    There was a lot of work done in the 80's and 90's on gas assisted ablation for PRK and LASIK. Some good and bad outcomes, one of which was that the plume of hot remodeled tissue went everywhere and was a biohazard! Mfgrs eventually went to a vacuum system for plume removal, which is what you see today.
