Description
Technical Field
The invention relates to the technical field of 3D printing thyroid gland models, in particular to a thyroid gland puncture model based on 3D printing and a manufacturing method thereof.
Background
The thyroid gland is the most voluminous classical endocrine gland, and is H-shaped, divided into left and right lateral lobes and a central isthmus. The isthmus may extend upward beyond the pyramidal lobes to the hyoid plane. The upper end of the thyroid lateral lobe reaches the middle part of thyroid cartilage, the lower end reaches the 6 th tracheal cartilage ring, and the rear part is flush with the height of cervical vertebrae of 5 th to 7 th. The isthmus is located anterior to the tracheal cartilage rings of items 2-4. The thyroid gland is extremely rich in blood supply, primarily supplied by a pair of upper and lower thyroid arteries, and in some people by the lowermost thyroid artery from the brachiocephalic trunk. The parenchyma of the thyroid gland is composed of a large number of follicles, and the secreted hormones include Thyroid Hormone (TH) and Calcitonin (CT). The former is synthesized by follicular epithelial cells, is stored in a follicular cavity outside the thyroid follicular epithelial cells in a colloid form, and plays an important role in regulating the functional activities of organisms such as growth, development, metabolism and the like; the latter is synthesized by thyroid parafollicular cells (also called C cells), and is mainly involved in regulating the calcium and phosphorus metabolism and homeostasis of the body.
Thyroid nodules are a common clinical disease. Epidemiological investigation shows that the detection rate can reach 19 to 67 percent by adopting high-resolution ultrasound, and the high-resolution ultrasound is common in women and old people. While the prevalence of thyroid nodules is high, only about 5% of thyroid nodules are malignant, and therefore clinical treatment of thyroid nodules focuses on the identification of benign and malignant. Fine needle aspiration cytology (FNAB) is the first test method for evaluating thyroid nodule malignancy and benign and malignant disease, has important value for thyroid nodule diagnosis and treatment, and is regarded as the gold standard for preoperative thyroid nodule diagnosis. However, the thyroid is rich in blood supply and is adjacent to important organs such as trachea, internal carotid artery and the like, so that the technical requirement of thyroid puncture operation is high, and if an operator is inexperienced, the thyroid puncture operation is likely to cause puncture failure, even bleeding and asphyxia at a puncture part and other adverse events. In recent years, with the popularization of ultrasonic technology, the incidence of thyroid nodules with a diameter of less than 1cm is increasing year by year, and the difficulty of thyroid gland puncture operation is further increased.
According to the above, in order to facilitate clinicians to comprehensively understand and master the key field of thyroid puncture, thyroid models are used in the teaching of the clinical or medical schools in the existing hospitals, and the existing traditional thyroid models are generally simple in structure and are mostly formed by plastic injection molding, so that the thyroid puncture model has many defects and shortcomings, specifically the following defects;
1. because the material is hard, can't be fine simulation human skin and blood flesh tissue, so the simulation effect is poor, is unfavorable for the student to know the concrete state of thyroid gland directly perceivedly.
