Embodiment Construction

[0071] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0072] See figure 1 , figure 1 It is a flow chart of a lung aided diagnosis method provided by an embodiment of the present invention, such as figure 1 As shown, the embodiment of the present invention provides a method for assisting lung diagnosis, comprising the following steps:

[0073] Step 101. Obtain the registration matrix of the electromagnetic navigation bronchoscope according to the preoperative CT image.

[0074] Before this step, preoperative CT planning is required first, such as planning the path of the electromagnetic navigation bronchoscopy system (ENB-TBLB) and the puncture needle path of the transthoracic electromagnetic navigation system (EMN-TTNA), and planning and marking the patient's skin Target puncture point on. Then the elec...

Abstract

The embodiment of the invention provides an auxiliary lung diagnosis method and device. The method comprises the following steps of acquiring a rectification matrix of an electromagnetic navigation bronchoscope according to a preoperative CT image; using a peripheral ultrasonic probe for acquiring a lesion image; performing on-site cytological evaluation under the condition that the lesion image is acquired; if an on-site cytology result is negative, conducting bronchoalveolar lavage and a trans-bronchoscope biopsy; inputting a puncture path and registration information to a trans-chest-wall electromagnetic navigation system; directing a puncture needle at a target puncture point on a person to be detected; adjusting the spatial angle of the puncture needle; acquiring a respiration curve of the person to be detected; when the puncture path of the puncture needle is overlapped with the input puncture path and the breathing time of the person to be detected is consistent with CT time, starting the puncture operation; after the puncture needle reaches a predetermined position, carrying out needle suction biopsy. Therefore, when an electromagnetic navigation bronchoscope biopsy is notideal, a trans-chest-wall puncture biopsy guided by electromagnetic navigation is performed, so that the diagnosis transit time of a patient is shortened to the maximum extent, and the puncture risk of the patient is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a lung auxiliary diagnosis method and device. Background technique [0002] Computed tomography (CT)-guided transthoracic biopsy (TTNA) is an effective method for diagnosing lung lesions, but because this technology cannot be guided in real time, it is difficult to accurately locate and diagnose some small lesions, and Repeated lung punctures are required, and repeated lung punctures may cause complications such as pneumothorax and bleeding. [0003] At present, TTNA under the guidance of electromagnetic navigation is commonly used. Compared with purely relying on CT positioning, accurate preoperative positioning and intraoperative real-time navigation can shorten the puncture time, reduce the radiation dose received by patients and the number of needle adjustments, and reduce the incidence of complications. . [0004] However, traditional electromagnetic navigation still requ...
