Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a tunnel type minimally invasive lung nodule resection device. BACKGROUND

[0002] At present, with the gradual improvement of people's living standards, the public's demand for health is increasing, and at the same time, with the progress of science and technology, the clarity of imaging examination has been greatly improved. Many early lung cancers represented by malignant lung nodules can be detected when the diameter is less than 3-4mm.

[0003] The current main treatment methods for lung nodules / early lung cancer are surgery and ablation therapy. Traditional thoracoscopy (VATS) requires resection of the lung segment or lobe containing the nodule. Even if wedge resection is used, it may still resect too much normal lung tissue, resulting in loss of lung function. Single-port thoracoscopy has only a 2-3cm incision, but deep nodules require resection of lung segments or even lobes, which has a significant impact on patients with poor lung function reserves (such as the elderly or patients with chronic lung disease). Ablation therapy cannot completely remove the lesion and relies on imaging to determine the inactivation effect. The scar formed after ablation may mask the signs of recurrence, leading to delayed detection. In addition, ablation may damage the tumor structure, increasing the risk of metastasis.

[0004] Therefore, there is an urgent need for a tunnel type minimally invasive lung nodule resection device that can provide a smaller surgical incision, less tissue damage, and preserve more healthy lung tissue in patients, while reducing postoperative recovery time and discomfort for patients, and effectively providing more accurate, convenient, and less invasive treatment for patients with small diameter lung nodules / early lung cancer.
