We present an image-guided laparoscopic surgical tool (IGLaST) to prevent bleeding. By applying optical frequency domain imaging (OFDI) to a specially designed laparoscopic surgical tool, the inside of fatty tissue can be observed before a resection, and the presence and size of blood vessels can be recognized. The optical sensing module on the IGLaST head has a diameter of less than 390 µm and is moved back and forth by a linear servo actuator in the IGLaST body. We proved the feasibility of IGLaST by in vivo imaging inside the fatty tissue of a porcine model. A blood vessel with a diameter of about 2.2 mm was clearly observed. Our proposed scheme can contribute to safe surgery without bleeding by monitoring vessels inside the tissue and can be further expanded to detect invisible nerves of the laparoscopic thyroid during prostate gland surgery.
我们提出了一种图像引导的腹腔镜手术工具（IGLaST）来防止出血。通过将光学频域成像（OFDI）应用于专门设计的腹腔镜手术工具，可以在切除前观察脂肪组织内部，并识别血管的存在和大小。IGLaST 头部的光学感应模块直径小于 390 µm，由 IGLaST 主体中的线性伺服执行器前后移动。我们通过对猪模型脂肪组织内部的活体成像证明了 IGLaST 的可行性，直径约为 2.2 毫米的血管被清晰地观察到。我们提出的方案可以通过监测组织内部的血管来帮助实现无出血的安全手术，并可以进一步扩展到在前列腺手术中检测腹腔镜甲状腺的不可见神经。
