Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is designed as a multicenter prospective trial of BTPNA for the diagnosis of peripheral pulmonary lesions in the real world. The purpose of the study is to evaluate the safety and effectiveness of BTPNA and to explore the factors of diagnosis rate.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will be conducted at about 10 clinical centers. Patients will be first screened, and only after meeting all the selection criteria, not meeting any exclusion criteria, and signing the informed consent, could they be enrolled in the group to receive BTPNA to sample the target lesions. The primary endpoint is the diagnostic yield of BTPNA. The secondary endpoints include the success rate of navigation, the operation time of the bronchoscope and so on.

Bronchoscopic Transparenchymal Nodule Access

Bronchoscopic Transparenchymal Nodule Access (BTPNA) is locating the lesion in the lung tissue guided by the bronchoscope navigation system (LungPro) in the natural lumen (bronchus), and automatically calculates the best point of entry (POE) and the best route to avoid blood vessels. An opening is made from the POE under the endoscope, and is extended with a balloon dilator. Combined with X-ray fluoroscopy, a sheath with a blunt-tip core is used in the lung parenchyma to reach the lesion site, and then biopsy diagnosis or treatment.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Patients older than 18 years old.
2. Newly diagnosed patients whose chest CT shows peripheral pulmonary lesions that have bronchus signs but are difficult to reach through the intrabronchial path, or are adjacent to the airway, or have no bronchus sign, and are suspected of malignancy which need non-surgical biopsies.
3. The diameter of the lesions is greater than or equal to 0.8cm and less than 5cm
4. The location of lesions results in the following situations where transthoracic needle aspiration (TTNA) is difficult to obtain a diagnosis or the operation is relatively risky, or have not been diagnosed by TTNA and other non-surgical biopsies in the past.
5. Lesions can be accessed by BTPNA technology in preoperative assessment.
6. Understand the research and sign the informed consent form.

Exclusion Criteria

1. Contraindications for bronchoscopy.
2. The lesions are adjacent to the target trachea or bronchus of points of entry(POE).
3. Severe cardiopulmonary dysfunction and other diseases that may significantly increase the risk of surgery.
4. Routine bronchoscopy showed visible lesions in the lumen.
5. The investigator believes that the patient has other conditions that are not suitable for inclusion in this study.
