Problems solved by technology

[0004] In order to solve the above problems, this disclosure proposes a virtual reality navigation method and system for spinal endoscopic surgery, which solves the problem that the existing spinal endoscope can only rely on intraoperative CT to place the endoscope in place channel, and the intraoperative endoscopic image The problem of inability to effectively observe the deep anatomical structure of the operation area can be effectively guided by the preoperative CT image to guide the positioning channel and expand the depth of view during the operation, thereby improving the efficiency and safety of spinal endoscopic surgery

Abstract

The invention belongs to the technical field of surgical navigation, and particularly relates to a virtual reality navigation method and system for a spinal endoscopic surgery, and the method comprises the following steps: planning an implantation channel position of a spinal endoscope in the body of a patient according to a preoperative CT image of the patient, and reconstructing a three-dimensional image of an operative area of the patient; tracking marks are installed at the tail end of a bone tissue and a spine endoscope in an operation area of a patient, and two-dimensional video images of the position and the posture of the spine endoscope in the body of the patient in the operation are obtained in real time; and establishing association between the reconstructed three-dimensional image of the operation area of the patient and the two-dimensional video image of the spine endoscope to realize virtual reality navigation of the spine endoscope operation.

Description

technical field [0001] The present disclosure belongs to the technical field of surgical navigation, and in particular relates to a virtual reality navigation method and system for spinal endoscopic surgery. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Spinal endoscopic minimally invasive surgery overcomes the defects of large trauma and long recovery period of traditional surgery, and is widely favored in the clinical field. However, due to the narrow field of view of the minimally invasive endoscope, the technical threshold of clinical operation is correspondingly high, which limits the promotion of spinal endoscopic surgery to a certain extent. In addition, the installation of the in-place guide channel of the endoscope needs to be completed under the guidance of CT fluoroscopy, which increases the amount of radiation received by p...
