Embodiment 1

[0078] Embodiment 1 Determination method of intersegmental marker points of the lung of the present invention

[0079] 1. Method for determining the intersegmental landmarks of the lung

[0080] The identifiable anatomical structures on the lung surface include the lung apex, the lung base, the lateral costal surface, the medial mediastinal surface, and the anterior, posterior, and inferior borders.

[0081] The remaining identifiable anatomical structures of the left lung are: the posterior end of the oblique fissure (the intersection of the oblique fissure and the posterior border) ( figure 1 A); the anterior lower corner of the left upper lung (the intersection of the oblique fissure and the anterior border) ( figure 1 A); the transition part between the anterior oblique fissure and the mediastinal surface of the pulmonary ligament in the lower lobe of the left lung ( figure 1 B) The bottom edge of the left lower lobe is divided into two parts, namely, the inner line of t...

Embodiment 2

[0136] Embodiment 2 The preparation method of the lung segment model of the present invention

[0137] According to the data of the identifiable anatomical structure of the lungs of each patient measured in Example 1, a lung model is prepared, then according to the position of the inter-segment marker points determined by the method of Example 1, each inter-segment marker point is installed on the lung model , so that anatomical segmentectomy is used, the lung segment model prepared by the method of the present invention is as follows:

[0138] Such as Figure 6 As shown, including: left lung segment, right lung segment; said left lung segment includes: left upper lobe, left lower lobe, left lung costal surface, left lung mediastinal surface; said left upper lobe and left lower lobe The junction of the lobes is the oblique fissure of the left lung; the upper lobe of the left lung includes: the posterior segment of the apex, the anterior segment of the left lung, and the tongu...

Abstract

The invention discloses a method for determining the intersegmental landmarks of the lung. The steps are as follows: (1) performing CT chest pulmonary venography and high-resolution thin-layer scanning on the lung to be examined; performing three-dimensional reconstruction on the original image; (2) determining The identifiable anatomical structure points and boundary lines on the lung surface, and use these structures as reference points to measure the relative positional relationship between the intersegmental position of each lung segment on the lung surface and the above-mentioned identifiable lung anatomical structure landmarks, and largely The data calculates the length ratio of its anatomical landmark line to determine the position of the intersegmental landmark. The invention also discloses a method for preparing a quantitative lung segment model. The method of the present invention can accurately determine the position of each inter-segment marker point, make the abstract inter-segment plane quantifiable, and guide the surgeon to perform precise lung segment resection. The anatomical structure is clear at a glance, and the application prospect is good.

Description

technical field [0001] The invention relates to a method for determining intersegmental landmarks of the lung and a method for preparing a quantitative lung segment model. Background technique [0002] In recent years, with the improvement of people's health awareness and the popularization of low-dose CT (LDCT) lung cancer screening, the detection rate of early "small lung cancer" has gradually increased. In the context of increasingly precise lung cancer treatment, segmentectomy is increasingly used in lung cancer surgery, and the goal of surgery is to preserve the patient's normal lung tissue to the greatest extent and reduce surgical trauma. [0003] However, there are still technical difficulties in anatomical segmentectomy: due to the lack of anatomical landmarks between lung segments, it is difficult to determine the extent of segmentectomy. In current clinical practice, the "lung inflation-collapse method" is usually used to determine the intersegmental plane: the t...
