Patent attributes
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.
