MID INFRARED LASER FOR MAXILLOFACIAL SURGERY

颅面/颌面外科手术用于矫正 因消融性癌症手术或其他原因引起的先天性缺陷和畸形 创伤性损伤。由于这些手术是复杂的和侵入性的，患者 通常需要在重症监护病房进行初步护理，并需要长时间的- 手术住院治疗。实时视频内窥镜检查的进展 放射成像和牵张成骨导致侵入性较小 程序；然而，目前使用的机械锯和钻头是 不适合内窥镜检查。 高功率光纤传输Er：YAG激光器的研制 骨头切割和轮廓重塑将是迈向 颌面部内窥镜手术的发展。关于建议的 第一阶段的工作，我们将建造一台20W的Er：YAG激光器，并将其连接到 新型触头光纤传输系统。骨消融术 激光系统的特性将在体外和体内进行评估 活体实验。 建议的商业应用： 基于激光的微创骨切割和轮廓重塑系统 在这个项目上开发的将导致改进的颌面部手术 与目前的技术相比，这将需要更短的住院时间。

Craniofacial/maxillofacial surgical procedures are used to correct congenital defects and abnormalities caused by ablative cancer surgery or traumatic injury. Since these surgeries are complex and invasive, patients often require initial care in an intensive care unit and lengthy post- operative hospitalization. Advances in videoendoscopy, real-time radiologic imaging, and distraction osteogenesis have led to less invasive procedures; however, the mechanical saws and drills currently in use are poorly suited to endoscopic procedures. The development of a high-power Er:YAG laser with fiber-optic delivery for bone cutting and recontouring would represent a significant step towards the development of endoscopic maxillofacial procedures. On the proposed Phase I effort, we will build a 20-W Er:YAG laser and interface it to a novel contact-tip fiber-optic delivery system. The bone ablation characteristics of the laser system will be evaluated by in vitro and in vivo experiments. PROPOSED COMMERCIAL APPLICATION: The minimally invasive laser-based bone cutting and recontouring system developed on this project would lead to improved maxillofacial procedures that would require shorter hospital stays compared to current techniques.
