Problems solved by technology

In the current percutaneous ablation process, a biopsy is required first and then a second ablation, but the existing puncture needles are prone to cause pneumothorax and pulmonary embolism, and there are great difficulties in precise puncture under respiratory motion

Embodiment 1

[0045] Such as Figure 1-3 As shown, a lung percutaneous puncture navigation method, including:

[0046]S10. Input the lung static image data of the target patient, and use the image segmentation method to obtain a three-dimensional surface model of the skin and various tissues in the same coordinate system;

[0047] S20. Based on the three-dimensional surface model of the skin and various tissues, a physical model is established to simulate the movement trajectory of the skin and various tissues during breathing;

[0048] S30. Based on the three-dimensional surface model of the skin, match the movement trajectory of the skin and tissue during the simulated breathing process with the real-time breathing scene of the patient, so as to carry out the linkage of the skin and various tissues for real-time virtual-real fusion display.

[0049] It also includes S40, using the respiratory phase of the static image as the standard phase, monitoring the current phase state in real time...

Abstract

The invention provides a pulmonary percutaneous puncture navigation method. The method comprises the following steps: inputting pulmonary static image data of a target patient, and obtaining a three-dimensional surface model of skin and tissues by adopting an image segmentation method; establishing a physical model by using the three-dimensional surface model, and simulating movement tracks of the skin and each tissue in a respiration process; and matching the simulated movement tracks with a real-time respiration scene of the patient, and performing linked real-time virtual-real-fused display on the skin and each tissue. According to the method, under the condition that only static CT image data exist, the movement tracks of the skin and all the tissues in the respiration process are simulated; the movement tracks are matched with an actual respiration position of the patient and a real position is displayed; when a skin surface model in a CT image is matched with an actual skin surface, puncture reminding information is generated, and the tumor puncture precision is improved; and dynamic movement tracks of simulated skin, tumors and other tissues and actual respiration shapes are displayed in a linked mode, and doctors are helped to conduct high-efficiency and high-accuracy puncture.

Description

technical field [0001] The invention relates to the field of surgical navigation, in particular to a navigation method and system for lung percutaneous puncture. Background technique [0002] In the prior art, rapid on-site assessment of specimens is used to solve the problem of benign and malignant assessment in minimally invasive surgery. Specifically, cell smears are collected during puncture, and cytopathologists quickly inspect the specimen cells on the spot, and the smears are analyzed through a microscope. The analysis of the sample draws a preliminary conclusion of whether the cells are benign or malignant, and provides guidance for the surgical plan. The whole process under the guidance of CT only takes 3-5 minutes. [0003] Currently, the morbidity and mortality of lung cancer remain high, and minimally invasive ablation therapy is one of the main methods for the treatment of such diseases. In the current percutaneous ablation process, a biopsy is required first a...
