随着更好的手术结果，更快的恢复时间，减少术后疼痛，并减少手术部位的疤痕，微创手术（MIS）的应用在过去30年中获得了很大的突出。手术实践的这一变化使外科医生无法像开放手术中那样触诊血管的存在。相反，他们必须依靠腹腔镜摄像机，不幸的是，摄像机无法检测到隐藏在组织下面的血管的存在。在某些情况下，外科医生可能会意外地切断血管，这可能导致严重的，甚至致命的并发症。在这里，我们展示了通过在腹腔镜抓钳的相对钳口上添加近红外LED和光电二极管，可以检测到埋在组织下的血管。我们显示的Monte Carlo模拟的结果，以支持我们的理论，从3至6毫米的血管埋在高达1厘米的组织可以检测和量化。该技术可以添加到现有的腹腔镜工具中，这些工具在钳口上的表面积有限，以在MIS手术期间辅助外科医生。(C)2018年，摄影光学仪器工程师协会（SPIE）
With better surgical outcomes, quicker recovery times, decreased postoperative pain, and reduced scarring at the surgical site, the application of minimally invasive surgery (MIS) has gained a lot of prominence in the last 30 years. This change in surgical practice has taken away the ability of a surgeon to palpate for the presence of a blood vessel as would occur in an open procedure. They instead must rely on a laparoscopic video camera feed that unfortunately cannot detect the presence of a blood vessel hidden beneath tissue. In certain scenarios, a surgeon can accidentally cut a blood vessel, which can lead to severe, even fatal, complications. Here, we show that by adding a near-infrared LED and a photodiode onto the opposing jaws of laparoscopic graspers, blood vessels buried under tissue can be detected. We show the results of Monte Carlo simulations to support our theory that the blood vessels ranging from 3 to 6 mm buried under up to 1 cm of tissue can be detected and quantified. This technology could be added to already existing laparoscopic tools that have limited surface areas on the jaws to assist surgeons during MIS procedures.
