Detachable Multicolor Light Source for Forceps - A Novel Supportive Tool for Surg

描述(申请人提供)：创伤性伤口含有失活的组织、细菌和相关的异物、草、土壤和骨骼碎片，这取决于受伤的方式和地点。在战争场景中，现代武器装备爆炸冲击造成的创伤通常更严重，异物种类更多。碎片可能包括武器炮弹、衣服上的布料、砾石、装甲上的陶瓷碎片，以及各种类型的弹片，比如用于简易爆炸装置的弹片。伤口还将包含大量失活的皮肤和肌肉组织，与健康组织网状连接。在最初的治疗阶段，伤口清创的速度和质量对于防止导致死亡和发病的感染类型至关重要。过去一个世纪发展起来的各种成像方法可以用来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、钳子和手术刀)来识别和移除物体和失活的组织。通常使用额外的天花板和前灯照明，但湿组织的散射光和手术器械的阴影显著降低了视觉对比度。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来照明感兴趣的区域，从而提高对比度，并更容易定位和识别伤口中造成的不同类型的碎片或错误地留在伤口中的手术物品，从而增强伤口中异物的可视化能力。这种方法将在一种可以连接到任何类型的手术钳上的多色照明器中实现。颜色控制将通过用户友好的滑动变阻器提供。紫外线辐射(可选)以区分强荧光异物也将被考虑在拟议的设计中。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。图像将在放置在手术支持设备车上的屏幕上观察到。提出了两种照明方案：1)墙供电装置，用于常规操作设施；2)电池供电装置，用于电力消耗受限的区域，如野战医院或偏远地区。 与公共卫生相关：拟议的用于钳子的可拆卸多色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造成的异物的能力。更高质量的伤口清创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。

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.
