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）：创伤性伤口含有失活的组织、细菌和相关异物、草、土壤和骨头碎片，具体取决于损伤发生的方式和地点。在战争场景中，现代武器的爆炸冲击造成的伤口通常更严重，并且被更多种类的异物污染。这些碎片可能包括武器外壳、衣服织物、砾石、盔甲陶瓷碎片以及各种类型的弹片，例如简易爆炸装置中使用的弹片。伤口中还会含有大量与健康组织交织在一起的失活的皮肤和肌肉组织。初始治疗阶段伤口清创的速度和质量对于预防导致死亡和发病的感染类型至关重要。上个世纪发展起来的各种成像方法可用于定位和可视化伤口中的一些物体，但通常外科医生仍然使用视觉观察和机械方法（手、镊子和手术刀）来识别并除去异物和失活的组织。通常，会采用额外的天花板和头灯照明，但来自湿组织的散射光和来自手术器械的阴影会极大地降低视觉对比度。智能光学系统提出，通过用与特定物体的色调相匹配的不同颜色的光照亮感兴趣的区域，从而提高对比度，并更容易定位和识别造成伤口的不同类型的碎片，从而增强可视化伤口中异物的能力。伤口内或手术物品误留在伤口内。该方法将在可连接到任何类型的手术钳上的多色照明器中实施。颜色控制将通过用户友好的滑动变阻器提供。在提议的设计中还将考虑用于区分高荧光异物的紫外线辐射（可选）。照明器中将安装一个微型摄像机芯片，以提供碎片的放大图像。将在手术支持设备推车上放置的屏幕上观察图像。提出了两种照明器选项：1）用于常规操作设施的壁式供电设备，以及 2）用于功耗受限区域（例如野战医院或偏远地区）的电池供电设备。 公共健康相关性：拟议的可拆卸多色镊子光源将增强军事和创伤外科医生以及急救人员清除因车辆事故、工业事故、火灾、现代武器或简易爆炸装置造成的伤口中的异物的能力。伤口清创质量的提高将减少创伤相关感染的数量，从而减少感染相关截肢的发病率和死亡率。
