项目摘要

DESCRIPTION (provided by applicant): Physical Sciences Inc., with our clinical partners in the Dept of Oral and Maxillofacial Surgery at the Massachusetts General Hospital, propose to develop a marking system for navigation during orthognathic surgery. The device can be used for both endoscopic and open procedures. It can be used to transfer treatment plans from computer-based 3D surgical planning tools or cephalometric tracings onto the bone. The system will provide for intraoperative registration of the image to the patient, with no requirement for fiducial markers in the pre-operative images and no fixation frame attached to the head. Examples of procedures where OsteoMark might be used include minimally-invasive (endoscopic) reconstruction and distraction osteogenesis. Once the marks are made, the surgeon will complete the procedure using instruments without any tracking, using the marks to guide the modification of bone. The proposed device will be less expensive and less complex than a system that tracks the motion of multiple surgical instruments as procedures are performed. We are proposing to develop navigation based on both 2D and 3D pre-operative images, though Phase I will address only the 3D images. OsteoMark will be developed to interact with the open-source medical imaging software Slicer/Osteoplan. In Phase I, we will fabricate the prototype marker, develop a rudimentary software interface for Slicer, and characterize its performance in a series of bench tests. The capstone feasibility demonstration will be a set of endoscopic procedures performed in porcine cadaver heads, from which we will quantify the performance of the marking device in an environment that closely resembles an operating-room. Public Health Significance: Minimally-invasive surgery is becoming more widely used in reconstruction of bones in the face because it results in faster recovery times, less pain and discomfort, and less scarring than open procedures. Another recent advancement has been the use of computer graphics tools to plan complex reconstruction operations. We are proposing to develop a device that will enable surgeons to copy computer treatment plans to the bone even through a very small incision, allowing surgeons to perform more sophisticated procedures with less difficulty for the patient.

描述(申请人提供)：物理科学公司与我们在马萨诸塞州总医院口腔颌面外科的临床合作伙伴提议开发一种正颌外科手术导航标记系统。该装置既可用于内窥镜手术，也可用于开放手术。它可以用于将治疗计划从基于计算机的3D手术计划工具或头影测量跟踪转移到骨骼上。该系统将为患者提供术中图像配准，不需要在术前图像中使用基准标记，也不需要固定框架连接到头部。可能使用OsteoMark的手术例子包括微创(内窥镜)重建和牵张成骨。一旦做了标记，外科医生就会在没有任何跟踪的情况下使用器械完成手术，使用这些标记来指导骨骼的修改。与在手术过程中跟踪多台手术器械运动的系统相比，拟议的设备将更便宜、更复杂。我们建议开发基于2D和3D术前图像的导航，尽管第一阶段将仅针对3D图像。OsteoMark将被开发为与开源医学成像软件Slicer/Osteoplan互动。在第一阶段，我们将制作原型标记器，为Slicer开发一个基本的软件界面，并通过一系列的台架测试来表征其性能。最大的可行性演示将是一套在猪头上进行的内窥镜检查程序，我们将从这些程序中量化标记设备在非常类似于手术室的环境中的性能。公共卫生意义：微创手术正越来越广泛地应用于面部骨骼重建，因为它比开放手术恢复时间更快，疼痛和不适更少，疤痕更少。最近的另一项进步是使用计算机图形工具来规划复杂的重建操作。我们提议开发一种设备，使外科医生能够将计算机治疗计划复制到骨骼上，即使是通过一个非常小的切口，使外科医生能够以较小的难度执行更复杂的手术。
