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.

为了提高骨科手术后的恢复速度，并克服传统机械器械用于截骨手术的几何和物理限制，激光加工已经应用于骨科手术，具有可接受的切割速度(8-15分钟)和良好的切割质量。然而，有报道称，激光加工设备的工作距离有限，并且在手术中会阻碍医生的视力。因此，提出了水射流制导激光(WJGL)，它以水射流为光纤，将激光能量传输到靶区，完成材料的去除。其较长的工作距离和较强的冷却效果显示了其在成骨手术中的巨大潜力。本项目的主要目标是实现WJGL在骨质疏松症上的成功应用，目的和目标包括：设计WJGL用于骨碎补的联接头；研究影响加工效率、坏死和损伤的关键因素；实现WJGL机用于医生手术的最小化；研究WJGL在骨上应用时的材料去除机理。
