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

描述（由申请人提供）：创伤性伤口包含失活组织、细菌和相关异物、草、土壤和骨碎片，具体取决于损伤发生的方式和位置。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、衣服上的织物、砾石、装甲上的陶瓷碎片以及各种类型的弹片，例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与健康组织相啮合的肌肉组织。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。在过去的世纪中开发的各种成像方法可以用于定位和可视化伤口中的一些物体，但是通常，外科医生仍然使用视觉观察和机械方法（手、镊子和手术刀）来识别和移除物体和失活组织。通常，应用额外的天花板和前灯照明，但是来自湿组织的散射光和来自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照亮感兴趣的区域来增强可视化伤口中异物的能力，从而提高对比度，并且使得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。该方法将在可附接到任何类型的手术钳的电致发光器中实现。颜色控制将通过用户友好的滑动变阻器提供。在拟定设计中还将考虑紫外线辐射（可选），以区分高荧光异物。一个微型摄像机芯片将被纳入照明器，以提供碎片的放大图像。将在放置在手术支持设备推车上的屏幕上观察图像。提出了两种照明器选项：1）用于常规手术设施的墙壁供电设备，以及2）用于受限功耗区域（如野战医院或偏远地区）的电池供电设备。 公共卫生相关性：拟议中的Forbes可拆卸多色光源将提高军事和创伤外科医生以及急救人员的能力，以清除因车祸、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。更高质量的伤口清创将减少创伤相关感染的数量，因此，导致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.
