Description

Technical Field

[0002] With the popularization of CT screening, the number of patients with early lung cancer mainly composed of ground glass opacity (GGO) has increased significantly. In some patients, the lesions are located under the pleura of the lung, close to the surface of the lung tissue. The pathological histological types of early lung cancer have also gradually begun to change. In early lung cancer with GGO as the main component, the pathological subtypes are mainly adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA).

[0003] Currently, surgical resection is the most effective treatment for early-stage lung cancer. Relevant studies on early-stage peripheral small lung cancer have found that for GGO lesions with a tumor length of ≤2 cm and a consolidation / tumor ratio (CTR) of ≤0.25, the 5-year recurrence free survival (RFS) of patients who underwent sublobar resection (wedge resection, segmentectomy) was 99.7%.

[0004] Currently, thoracoscopic wedge resection, segmentectomy, and electromagnetic navigation microwave ablation can be used, but these treatment methods still face the following problems:

[0005] 1. Surgery will remove too much normal lung tissue, causing the patient to lose too much lung function after surgery;

[0006] 2. The pathological positivity rate of electromagnetic navigation microwave ablation for ground glass nodules is low, with literature reporting less than 5%. In addition, ablation is faced with risks such as intraoperative pneumothorax, intrathoracic hemorrhage, repeated blood in sputum after surgery, hemoptysis, and fungal cavities.

The closed end of the outer cylinder 210 is provided with an external through hole 211 that is connected to the hollow sleeve 240. A plurality of cutting knives 250 are arranged at different heights and different orientations below the cover plate 230, so that all subsequent cutting knives 250 do not interfere with each other during the rotation process. When all the cutting knives 250 are arranged, the gap between two adjacent cutting knives 250 is very small. A tie 260 for tying the lung tissue to be cut is arranged below the lowest cutting knife 250, and the tie 260 and the The cover plate 230 is movably matched, and a rotating mechanism 270 is fixed on the outer cylinder 210 and the hollow sleeve 240, and the tail end of each cutting knife 250 is fixed to the rotating mechanism 270 respectively, and the rotating mechanism 270 simultaneously drives the tip ends of multiple cutting knives 250 to rotate toward the axis of the inner cylinder 220 to cut the lung tissue to be cut. During the rotation of the cutting knife 250, the tip end of the cutting knife 250 passes the axis line of the inner cylinder 220. When the multiple cutting knives 250 rotate under the action of the rotating mechanism 270, the tip ends of all the cutting knives 250 cross in the up and down directions, thereby ensuring that the lung tissue to be cut can be cut.

[0035] In addition, a plurality of support plates 212 are provided on the inner wall of the outer tube 210 below the cover plate 230 , and the cable tie 260 is limited and guided by the plurality of support plates 212 , so as to facilitate the cable tie 260 to complete the binding.

[0038] The cutting knife 250 is in an arc shape, and the cutting edge of the cutting knife 250 is located on the inner circle. All the cutting knives 250 are distributed in a circle. The number of the cutting knives 250 can be two or three, and the specific number is determined according to the product size.

[0039] Example 4

[0040] like Figure 4 , Figure 5 As shown, this embodiment is a further improvement on the basis of Embodiment 2 or 3, and the details are as follows:
