Embodiment Construction

[0048] The surgical navigation system is to accurately correspond the patient's preoperative or intraoperative image data with the patient's anatomical structure on the operating bed, track the surgical instruments during the operation, and update and display the position of the surgical instruments on the patient's image in real time in the form of a virtual probe, so that the doctor The position of the surgical instrument relative to the patient's anatomy can be seen at a glance, making the surgical operation faster, more precise and safer. In the surgical navigation system, the most important process is the registration process. Through registration, the actual entity in the real environment can be connected with the coordinates in the computer, so as to realize the combination of real and virtual surgical planning and ensure the accurate execution of the surgical plan. Feature extraction is the key to registration technology, and accurate feature extraction provides a guara...

Abstract

This application discloses a surgical navigation system using structured light image registration and a registration signal acquisition method. The system includes a structured light navigator, a static reference, an end effector and a control computer; the structured light navigator is equipped with two cameras, The camera is used to scan the face, obtain a 3D image, and send the 3D image to the control computer; there are visible light marks on the static reference; the control computer is used to process the image and register the processing result with the original model; The computer is provided with a display screen for displaying registration results and monitoring completion status. The surgical navigation system provided by this application obtains the 3D point cloud image of the patient's face through structured light scanning, and registers it with the original model. It has the characteristics of large amount of information, fast acquisition speed, and many feature points. When the reconstructed data is used for surface registration, the registration accuracy is higher; the problem of insufficient feature points and low registration accuracy of traditional registration is improved.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular to a surgical navigation system using structured light image registration. In addition, the present application also relates to a registration signal acquisition method of the surgical navigation system using structured light image registration. Background technique [0002] Compared with other types of surgery, neurosurgery is unique in that the nerves and blood vessels are intricate, the brain tissue and other structures are very fine, and their functions are extremely important. A little carelessness will damage the blood vessels and nerves, resulting in serious disability or even life-threatening; In addition, the degree of mobilization of the nervous system structure is low, and it cannot be pulled and moved arbitrarily during the operation. Therefore, in traditional neurosurgery, more skull structures are often sacrificed in order to expose the lesion. T...
