Making method of transbronchoscopic lymph node puncture training model using three-dimensional printing

Abstract

The invention provides a making method of a transbronchoscopic lymph node puncture training model using three-dimensional printing. The making method comprises the following steps: firstly, acquiringstructural information of throats, tracheas and bronchi of different persons through CT and three-dimensional reconstruction techniques, and making a plurality of airway models conforming to a real clinical anatomical structure via a three-dimensional printing technique; then, making simulated lymph nodes stuck on corresponding positions of the outer sidewalls of bronchi, a simulated jaw model aswell as a shell for sheltering and fixing a bronchus model; and finally, assembling various parts in accordance with anatomical positions, and covering the outermost layer with the shell. According tothe making method of the transbronchoscopic lymph node puncture training model using three-dimensional printing provided by the invention, the airway structures of the training model are highly similar to the structure of a real case, and the various airway structures in the training model are different in structure and difficulty degree, so that a training process is closer to a real clinical operating environment, and the difficulty of the training process is gradually improved; therefore, the training effect is enhanced.

Description

technical field [0001] The invention relates to a bronchoscope training model, in particular to a method for making a three-dimensionally printed transbronchoscope lymph node puncture training model. Background technique [0002] Needle aspiration biopsy through bronchoscope is a special puncture needle with a flexible catheter, which is sent into the airway through the biopsy channel of the fiberoptic bronchoscope, and then penetrates the wall of the airway to treat tracheal and bronchial lesions, such as knots. It is a new technology for acupuncture suction of nodules, masses, enlarged lymph nodes and lung lesions, and to obtain cell or tissue samples for cytological and pathological examination. Needle aspiration biopsy via bronchoscope is widely used in the qualitative diagnosis of lesions close to the trachea and peribronchus, and allows bronchoscopic techniques to participate in the clinical staging of malignant tumors. operate. At present, most of the training is vi...

Problems solved by technology

Needle aspiration biopsy via bronchoscope is widely used in the qualitative diagnosis of lesions close to the trachea and peribronchus, and allows bronchoscopic techniques to participate in the clinical staging of malignant tumors. operate

At present, most of the training is virtual bronchoscopic simulation technology and fiberoptic bronchoscope training box. Although these existing technologies can be used for operational training, there is still a gap between the specific shape of each tissue and organ model of the respiratory system and the real one, relative spatial position and adjacent structure. It is not accurate enough, the selection of materials is unreasonable, and the bronchial structure of the training model is the same, there is no difference in difficulty, so it cannot meet the actual clinical requirements, and the trainers cannot master the process, skills and techniques of transbronchial needle aspiration biopsy
