Chest model capable of being used for percutaneous pulmonary nodule puncture under guidance of CT imaging

Abstract

The invention discloses a chest model capable of being used for percutaneous pulmonary nodule puncture under CT imaging guidance, which comprises a simulated human chest model and a pulmonary nodule model, the simulated human chest model is provided with skin, fat, muscle tissue, pleural membrane and lung tissue in a simulated manner from outside to inside, the simulated human chest model is internally provided with a cardiovascular system and a skeleton system in a simulated manner, the pulmonary nodule model is embedded in lung tissue, a training doctor can carry out whole-course, full-simulation, repeated and multi-part needle biopsy training of CT-guided percutaneous paracentesis with the model, the practical ability of the needle biopsy is rapidly improved, the basic operation skill of the CT-guided percutaneous pulmonary nodule paracentesis is mastered skillfully, the success rate is increased, the risk is reduced, the medical level is improved, the problem of practical training of CT-guided percutaneous puncture biopsy in various hospitals at present is solved, the medical safety is guaranteed, the medical diagnosis and treatment level is promoted, and the CT-guided percutaneous puncture biopsy model is scientific, practical and suitable for standardized promotion and popularization of CT-guided percutaneous puncture.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a chest model that can be used for percutaneous pulmonary nodule puncture under the guidance of CT imaging. Background technique [0002] CT-guided percutaneous puncture has become a basic, important and indispensable medical skill in medical diagnosis and treatment measures such as CT-guided percutaneous puncture drainage, positioning, biopsy, radiofrequency ablation, and seed implantation in clinical work. It requires the puncture doctor to master the puncture skills proficiently and accurately puncture the target lesion. Accurate and safe CT-guided puncture improves the accurate diagnosis and treatment of patients and reduces the risk of patients. [0003] The skills of this CT-guided percutaneous puncture firstly need to be improved by the puncture doctor through continuous practical training on the basis of theory. Limited to a small number of simple thoracentesi...

Problems solved by technology

[0003] The skills of this CT-guided percutaneous puncture firstly need to be improved by the puncture doctor through continuous practical training on the basis of theory. Limited to a small number of simple thoracentesis drainage phantoms, they can neither be used for CT imaging, nor can they be used for accurate positioning guidance; in clinical practice, most CT-guided percutaneous puncture training is performed directly on the patient, and there is a Greater uncertainty and risk, often have greater or fatal complications in practice

This also hinders the popularization and standardization of this important medical technology to a certain extent, and affects the uneven development of clinical work in hospitals across the country.

[0004] The initial training of doctors is limited to simple thoracentesis drainage phantom, which can neither be used for CT imaging nor have accurate positioning guidance. Most doctors perform CT-guided percutaneous puncture training on patients. Operational training, greater uncertainty and risk, often with greater or fatal complications
