Neurosurgical instrumentation over the last two decades has improved with the increasing use of the operating microscope and has provided much better visualization and lighting of the surgical field. During this time, dissecting instruments have become smaller, but they sacrifice some of the microscopic gains because they are made of opaque metal. This has the disadvantage of hiding from the surgeon the area of the surgical field being worked on. This paper reports the development of transparent instruments that are strong enough to be used in dissection and yet do not sacrifice part of the improved visualization and lighting gained with the operating microscope. Made of a high-strength plastic, these instruments can be used for dissection in surgical procedures and allow the surgeon to look through them and observe the tissues underneath. He can watch the condition of blood vessels and nervous tissues with an improved visibility that can help to avoid damage to delicate structures. Furthermore, as hidden structures such as small vessels come into view they are identified earlier. These instruments can also incorporate jeweled cutting edges and use their optical properties to improve further visualization of the surgical field.
在过去二十年中，随着手术显微镜使用的增加，神经外科手术器械得到了改进，手术视野的可视化和照明条件有了很大改善。在此期间，解剖器械变得更小，但由于它们由不透明金属制成，牺牲了一些显微镜带来的优势。这有一个缺点，即向外科医生隐藏了正在操作的手术区域。本文报道了透明器械的研发，这种器械足够坚固，可用于解剖，同时又不会牺牲手术显微镜所带来的可视化和照明的改善。这些器械由高强度塑料制成，可用于外科手术中的解剖，允许外科医生透过它们观察下面的组织。他可以更清晰地观察血管和神经组织的状况，这有助于避免损伤脆弱结构。此外，当诸如小血管等隐藏结构进入视野时，可以更早地识别它们。这些器械还可以采用镶宝石的刀刃，并利用其光学特性进一步改善手术视野的可视化。
