Chest Model Used for the Percutaneous Pulmonary Nodules Puncture under the Guidance of CT Imaging
The invention relates to the technical field of medical instruments, in particular to a chest model used for the percutaneous pulmonary nodules puncture under the guidance of CT imaging.
CT-guided percutaneous puncture has become a basic, important and essential medical skill in clinical work, such as CT-guided percutaneous puncture drainage, localization, biopsy, radiofrequency ablation, particle implantation, etc. It requires the puncture doctor to master the puncture skills skillfully and puncture the target lesion accurately. Accurate and safe CT-guided puncture improves the accurate diagnosis and treatment of patients and reduces the risk of patients.
This skill of CT-guided percutaneous puncture needs to be improved by continuous practice training on the theoretical basis. However, at present, in clinical practice, when
CT-guided percutaneous puncture is carried out, the initial training of doctors is limited to a small number of simple thoracic puncture and drainage phantom, which can neither be used for CT imaging nor accurate positioning and guidance. In clinical practice, most
CT-guided percutaneous puncture training is the direct operation training on patients, which has great uncertainty and risk, and there are often big or fatal complications in practice. It also hinders the popularization and standardization of this important medical technology to some extent, and affects the uneven development of clinical work in hospitals around the world.
