The invention discloses a device for surgical navigation. The device comprises an infrared positioning and tracking unit, a surgical scene camera shooting unit, a control unit and a calculation unit. The infrared positioning and tracking unit only comprises an infrared camera and an infrared light source, and the surgical scene camera shooting unit comprises at least one visible light camera. The control unit sends exposure signals to all the infrared cameras and the visible light cameras, all the infrared cameras and the visible light cameras are triggered to start exposure at the same time, the infrared cameras and the visible light cameras output collected images, and the images are acquired by controlling the image acquisition frequency. Therefore, before the control unit sends out the next exposure signal, image acquisition is completed and the image is transmitted to the calculation unit. According to the device provided by the invention, the cameras are synchronously exposed, so that the image jamming
