Conventional surgical navigation requires for surgeons to move their sight and conscious off the surgical field when checking surgical tool's positions shown on the display panel. Since that takes high risks of surgical exposure possibilities to the patient's body, we propose a novel method for guiding surgical tool position and orientation directly in the surgical field by a laser beam. In our navigation procedure, two cross-sectional planar laser beams are emitted from the two laser devices attached onto both sides of an optical localizer, and show surgical tool's entry position on the patient's body surface and its orientation on the side face of the surgical tool. In the experiments, our method gave the surgeons precise and accurate surgical tool adjusting and showed the feasibility to apply to both of open and percutaneous surgeries.
传统的手术导航要求外科医生在查看显示面板上显示的手术工具位置时，将视线和意识从手术区域移开。由于这会使患者的身体暴露在手术的风险中，我们提出了一种通过激光束直接在手术区域引导手术工具位置和方向的新方法。在我们的导航过程中，两个截面平面激光束从附着在光学定位器两侧的两个激光设备中发出，并显示手术工具在患者身体表面上的进入位置及其在手术工具侧面上的方向。在实验中，我们的方法为外科医生提供了精确和准确的手术工具调整，并显示了将其应用于开放和经皮手术的可行性。
