Problems solved by technology

However, since the percutaneous lung puncture operation needs to complete the entire positioning operation under CT monitoring, this not only increases the patient's CT radiation dose, but also increases the patient's operation complexity and dependence on the CT room, which to a certain extent makes clinical work difficult. become complicated

Embodiment 1

[0040] This embodiment provides an integrated scanning and positioning method for pulmonary nodules, which includes the following steps: (1) Obtain CT data when the patient is admitted to the hospital, and burn it to a CD in DICOM format, which is the most original spatial position of the patient's pulmonary nodules. Information is the basis for subsequent CT information analysis; (2) if figure 1As shown, the patient lies supine on the examination bed of the positioning device, and then obtains the anatomical standard position information of the chest surface of the patient according to the actual position of the patient in the supine or lateral position; through the information processing system, it is compared with the acquired CT data information, Complete the registration of CT information. The information processing system can support 3D information processing, by performing three-dimensional reconstruction on the patient's CT data information; (3) using the information p...

Embodiment 2

[0044] This embodiment provides an integrated scanning and positioning device 10 for pulmonary nodules used in the scanning and positioning method, such as figure 2 As shown, it includes: a data processing system with 3D data information scanning, analysis, reconstruction, and comparison. The data processing system is set in the integrated scanning positioning device 10 and can support 3D information processing; Three-dimensional reconstruction; a 3D printing component for 3D printing the puncture path designed on the three-dimensional model of the patient's chest, used for 3D printing the puncture guide channel model 50; a freely movable electromagnetic signal transmitter 20; and several The electromagnetic signal receiver 30 supporting the electromagnetic signal transmitter is used to receive the electromagnetic signal emitted by the electromagnetic signal transmitter 20 to determine the position of the puncture anchor point on the surface of the patient's chest; and a freel...

Embodiment 3

[0049] The present embodiment provides an operation method of the integrated scanning and positioning device for pulmonary nodules, which specifically includes the following steps: (1) importing the CT information of the patient into the data processing system of the positioning device; (2) lying on the patient's back On the examination bed of the positioning device, according to the actual position of the patient lying down, the information processing system automatically compares the imported patient CT information; (3) through the information processing system and the patient CT information. three-dimensional model, and design the puncture path and puncture position for positioning the needle puncture on the three-dimensional model of the patient's chest; (4) place the electromagnetic signal transmitter wirelessly connected with the electromagnetic signal receiver on the surface of the patient's chest, move The electromagnetic signal transmitter is used to make the position ...

Abstract

The invention discloses an integrated scanning and positioning method for pulmonary nodules and positioning equipment. The positioning method comprises the following steps: (1) acquiring CT information of a patient; (2) determining the body position of the patient according to the nodule position, and performing comparative registration on the CT information of the patient by an information processing system; (3) reconstructing a three-dimensional model of the thorax of the patient according to the CT information of the patient, and designing a puncture path and a puncture position; (4) determining a puncture positioning point on the surface of the thorax of the patient; (5) preparing a puncture guide channel model according to the designed puncture path; (6) performing puncture positioning on the surface of the thorax of the patient along the guide channel. With the adoption of the integrated scanning and positioning method for pulmonary nodules provided by the invention, medicine imaging science, engineering science, 3D printing and other technologies are combined, and corresponding positioning equipment is designed. When nodule positioning is performed, the pulmonary nodule positioning operation difficulty can be obviously simplified, the clinical operation is conveniently performed, and the patient is avoided from receiving extra CT radiation.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to an integrated scanning and positioning method and positioning equipment for pulmonary nodules. Background technique [0002] At present, with the wide application of high-resolution CT in lung cancer screening, the disease spectrum of lung cancer has changed significantly. Among them, there are more and more patients with early-stage lung cancer in clinical practice; especially the patients with pulmonary nodules mainly composed of ground-glass opacity (GGO). The proportion in clinical work is increasing year by year. Therefore, the treatment of pulmonary nodules with GGO has become a hot research field in thoracic surgery in recent years. [0003] From a clinical point of view, although due to the advancement of diagnosis and the popularization of lung cancer screening, more early-stage small nodular lesions have been discovered; however, the surgical treatment o...
