Laser blade on osteolomy

为了提高骨手术后的恢复速度，克服传统机械截骨器械的几何和物理限制，激光加工已应用于骨手术，切割速度可接受（8-15min），切割质量优异。然而，据报道，激光加工设备的工作距离有限，并妨碍医生在手术时的视力。为此，提出了水射流制导激光器（WJGL），利用水射流作为光纤将激光能量传输到目标区域，完成材料的去除。它的工作距离长，冷却效果强，在骨科方面显示出很大的潜力。此外，WJGL不仅保证了激光加工的加工质量，而且有效地防止了骨坏死。本课题的主要目标是实现WJGL在骨学上的成功应用。目的和目标包括：设计用于骨科应用的耦合头；研究影响加工效率、坏死和损伤的关键因素；实现WJGL医生手术机的最小化；目的：研究骨用WJGL去除材料的机理。

For a better recover speed after bone surgery, and to overcome the geometrical and physical limitations of the conventional mechanical instruments used to perform osteotomies, laser processing has already been applied to bone surgery with acceptable cutting speed (8-15min) and excellent cutting quality. However, It has been reported that Laser processing equipment has limited working distance, and obstruct the vision of doctors during surgery. Therefore, Water jet guided laser(WJGL) is proposed, which uses water jet as optical fiber to transport laser energy to target area and accomplish material removal. Its longer working distance and stronger cooling effect show great potential on osteolomy. In addition, WJGL not only ensure the machining quality as laser processing, but also effectively prevent the necrosis of bone.The main target of this project is to realize successful application of WJGL on osteolomy.The aims and objectives contain: To design the coupling head for osteolomy application; To study the key factors affecting machining efficiency, necrosis, and damage; To realize the minimization of WJGL machine for doctor's operation; To study the mechanism of material removal when use WJGL on bone.
