Abstract: A surgery system includes a contactless control panel, an infrared camera, a computer and a display. The contactless control panel includes control areas which are arranged in a predetermined pattern and are coated with infrared reflective material to reflect infrared radiation. The infrared camera captures an infrared image of the control areas. The computer performs image recognition on the infrared image, determines, based on the predetermined pattern stored in advance and a result of the image recognition, which one of the control areas is masked, and generates a device control signal based on a function corresponding to the one of the control areas that is determined to be masked. The display device displays images based on the device control signal.

Abstract: A surgical position calibration method for getting the augmented and mixed reality of a surgical instrument includes the following steps: placing a calibration plate under a C-ARM to take C-ARM images, with the calibration plate provided with geometric patterns; inputting the C-ARM images into a computer to make 2D image maps; finding the center point of each geometric pattern on the calibration plate; defining a first reference calibration point; finding the distance between the center point of each other geometric pattern and the first reference calibration point to set up a translation matrix formula to form a 3D space image map; placing a surgical instrument at any position above the calibration plate; using the translation matrix formula generating a spatial variation image for the displacement of the surgical instrument; and forming a new spatial variation image.

Abstract: An active calibration device is provided for obtaining parameters that are used to calibrate information contained in images captured by an infrared camera device. The active calibration device includes a base having at least one mounting surface; and a plurality of infrared (IR) light emitting components disposed on the mounting surface of the base. The IR light emitting components are arranged to form a predetermined pattern, and are configured to emit infrared light for receipt by a lens of the infrared camera device.

Abstract: The invention discloses an object developing and calibrating method in a surgical environment. The method mainly includes the steps of: using at least one infrared LED (IR-LED) and at least one infrared sensor (IR-Sensor) on a surgical eyeglass, to have a surgical environment image; and retaining image signals within a first wavelength range and removing image signals not in the first wavelength range in the surgical environment image. The method helps the surgeon see only the object images on the surgical eyeglass without the interference of non-surgical environmental imaging noises.

Abstract: This present invention discloses an image guided augmented reality method, comprising the following steps of: obtaining a first conversion matrix of a camera and a marked point; obtaining a second conversion matrix of the eye and the camera; linking the first conversion matrix and the second conversion matrix to obtain a correct position corresponding matrix of the eye to the marked point; and linking the correct position corresponding matrix to a position feature of the marked point to obtain the correct position of the eye to the marked point. The present invention also discloses a surgical navigation method of wearable glasses, used for obtaining the correct position of the operator's eye to the marked point.

Abstract: Using the surgical instrument guidance system of the present invention, a doctor can instantly obtain a real field of view of a surgical site of a patient, a three-dimensional medical image that coincides with a surgical site of the patient, and a real-time positional relationship between the surgical instrument and the surgical site of the patient. The surgical instrument guidance system provides an entrance guiding interface, an angle guiding interface and a depth guiding interface to help the surgeon monitor whether the position relationship between the surgical instrument and the patient's surgical site conforms to the preoperative planning and specifically increases the accuracy of position, angle and depth of the surgical instrument on the surgical site of the patient.
