Surgical navigation method

Abstract

The invention discloses a surgical navigation method. The surgical navigation method comprises the following steps that a three-dimensional virtual image generating device receives data of a patient body for three-dimensional reconstruction so as to obtain a virtual model; a spatial location device recognizes recognition features on the patient body, and spatial data is obtained; a spatial data processing terminal receives the spatial data, and computation and calibration of three-dimensional space coordinates are conducted; a optical head-mounted display receives the three-dimensional space coordinates and the virtual model, then the virtual model and a patient body part are fused through the augmented reality technology and mapped on a display screen of the optical head-mounted display so as to assist with surgical navigation. According to the method, the image model data is utilized so that a doctor can be helped to select an optimal surgical pathway, the location accuracy is improved, the surgical injury is reduced, the damage to nearby tissue is reduced, and accordingly the surgical success rate is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, more precisely, it relates to a surgical navigation method. Background technique [0002] In the medical and health industry, the rudimentary traditional equipment, the lack of resources, the regional gap in medical level, and the lack of professional talents have all caused the current difficult situation and are also a double-sided shield to promote the application of new technologies. [0003] Traditional intraoperative navigation, intraoperative monitoring, and interventional therapy are performed under the guidance of images under the guidance of fluoroscopy, ultrasound, and MRI during the operation. [0004] This has led to the fact that the treatment process is completely dependent on the doctor's experience and skills, resulting in the instability of the surgical effect. At the same time, because techniques such as fluoroscopy and MRI rely or partially rely on X-ray irradiation, a larg...

Problems solved by technology

[0004] This leads to the fact that the treatment process is completely dependent on the doctor's experience and skills, resulting in the instability of the operation effect.

At the same time, due to technologies such as fluoroscopy and MRI, relying or partially relying on X-ray irradiation, a large amount of radiation is generated during the image-guided process, which will cause secondary damage to doctors and patients to varying degrees.
