DESCRIPTION (provided by applicant): Traumatic wounds contain devitalized tissue, bacteria and associated foreign bodies, grass, soil, and bone fractions, depending on how and where the injury occurred. Wounds caused by blast impact from modern weaponry in war scenarios are usually more severe, and are contaminated with an even greater variety of foreign bodies. The debris can include weapon shells, fabric from clothing, gravel, ceramic shards from armor, and various types of shrapnel, such as those used in improvised explosive devices. The wound will also contain a mass of devitalized skin and muscle tissue meshed with healthy tissue. The speed and quality of wound debridement in the initial treatment stage are crucial to prevent the type of infections that lead to mortality and morbidity. Various imaging methods that have been developed in the past century can be used to locate and visualize some of the objects in the wound, but as a rule, the surgeon still uses visual observation and mechanical methods (hand, forceps, and scalpel) to identify and remove the objects and devitalized tissue. Often, additional ceiling and headlight illumination is applied, but the scattered light from the wet tissue, and shadows from the surgical instruments dramatically reduce the visual contrast. Intelligent Optical Systems proposes to enhance the ability to visualize foreign bodies in wounds by illuminating the area of interest with different colors of light that match the hues of specific objects, thereby improving contrast, and making it easier to locate and identify different types of debris inflicted in the wound or surgical articles mistakenly left in the wound. This method will be implemented in a multicolor illuminator that can be attached to any type of surgical forceps. The color controls will be provided via a user friendly sliding rheostat. UV radiation (optional) to distinguish highly fluorescent foreign bodies will also be considered in the proposed design. A miniature video camera chip will be incorporated in the illuminator to provide a magnified image of the debris. The image will be observed on a screen placed on the surgery supportive equipment cart. Two illuminator options are proposed: 1) a wall powered device for use in regular operating facilities, and 2) a battery operated device for use in areas of restricted power consumption, such as field hospitals or remote locations. PUBLIC HEALTH RELEVANCE: The proposed Detachable Multicolor Light Source for Forceps will enhance the ability of military and trauma surgeons, and first responders, to remove foreign bodies inflicted in wounds caused by vehicular accidents, industrial accidents, fire, modern weaponry, or improvised explosive devices. The higher quality of wound debridement will decrease the number of trauma related infections, and as a result, lead to a reduced number of infection related amputations morbidities and mortalities.

描述（由申请人提供）：创伤性伤口含有不稳定的组织，细菌和相关的异物，草，土壤和骨骼分数，具体取决于损伤的方式和何处。战争场景中现代武器造成的爆炸撞击造成的伤口通常更为严重，并且被各种各样的异物污染。这些碎片可以包括武器壳，衣服，砾石，装甲的陶瓷碎片以及各种类型的弹片，例如在简易爆炸装置中使用的碎片。伤口还将包含大量的降级皮肤和与健康组织啮合的肌肉组织。初始治疗阶段的伤口清创术的速度和质量对于防止导致死亡率和发病率的感染类型至关重要。过去一个世纪已经开发的各种成像方法可用于定位和可视化伤口中的某些物体，但是通常，外科医生仍然使用视觉观察和机械方法（手，钳和手术刀）来识别和去除对象和贬低的组织。通常，应用了其他天花板和大灯照明，但是湿组织的散射光，外科仪器的阴影大大减少了视觉对比度。智能光学系统提议通过用不同的光线来触发感兴趣的领域，以与特定物体的色调相匹配，从而改善对比度，从而更容易找到和识别在伤口或手术物质中造成的不同类型的碎屑，从而提高感兴趣的区域，从而提高伤口中异物的能力。该方法将在可以连接到任何类型的手术钳上的多色照明器中实现。颜色控件将通过用户友好的滑动恒星提供。在拟议的设计中，还将考虑区分高荧光异物的紫外线辐射（可选）。微型摄像机芯片将在照明器中合并，以提供碎屑的放大图像。将在放置在手术支持设备手术室上的屏幕上观察图像。提出了两个照明器选项：1）用于常规操作设施中的墙供电设备，以及2）电池操作的设备，可用于有限的功耗区域，例如现场医院或远程位置。 公共卫生相关性：拟议的可拆卸多色光源将增强军事和创伤外科医生的能力，以及第一反应者，消除因车辆事故，工业事故，火灾，现代武器或即兴爆炸装置而导致的伤口造成的外国尸体。较高的伤口清创质量将减少与创伤相关的感染的数量，从而减少与感染相关的截肢性和死亡率减少。
