Embodiment Construction

[0022] In order to make the present invention more obvious and understandable, the preferred embodiments are described in detail as follows in conjunction with the accompanying drawings:

[0023] Such as Figure 1-2 As shown, the technical solution adopted by the present invention is to provide a 3D printing-based visceral aneurysm interventional operation operation model, the operation model is made of transparent materials through 3D printing; The passage is a continuously connected passage; the passage is a closed passage with two openings, and the passage is provided with a protrusion protruding from the outside of the passage for simulating the position and shape of a human hemangioma. The openings include a water inlet 1 for connecting to a water source and another water outlet 2 for simulating an arterial puncture point. The protrusions are provided in plural.

[0024] The present invention provides a method for making a 3D printing-based interventional operation mode...

Abstract

The invention relates to a visceral aneurysm interventional operation model based on 3D printing and a manufacturing method, and belongs to the technical field of medical teaching aids. The operation model is made of a transparent material through 3D printing; the operation model comprises a continuously communicated channel for simulating a cardiovascular system lumen in human viscera; the channel is a closed channel with two openings, and a protrusion which is used for simulating the position and the shape of human hemangioma and protrudes out of the outer side of the channel is arranged in the channel. According to the invention, the state of the aneurysm in a circulating state can be simulated in vitro; the catheter is used for performing in-vitro simulated embolism operation on the aneurysm; the model is made of a full-transparent material, so that observation is facilitated, the relationship between the manipulation of a doctor and the catheter state can be understood favorably, and the doctor is helped to improve the operation skill of the aneurysm embolism; the device can be used as a teaching aid for propaganda and education of patients and medical teaching. The lumen simulating the human visceral cardiovascular system is manufactured through the 3D printing technology, and the water tightness and the reality sense of the model are fully guaranteed.

Description

technical field [0001] The invention relates to a 3D printing-based simulated visceral aneurysm interventional operation model and a manufacturing method, belonging to the technical field of medical teaching appliances and interventional simulation appliances. Background technique [0002] Visceral aneurysms are aneurysms that occur in the visceral branches of the abdominal aorta. Among them, splenic aneurysm is the most common, followed by hepatic aneurysm and superior mesenteric aneurysm. They also occur in the celiac artery, renal artery, and omental artery. and aneurysms of the inferior mesenteric artery. With the improvement of modern people's quality of life and diagnostic technology, there are more and more cases of visceral aneurysms found in clinical examination. Its threat to the human body mainly lies in the sudden rupture of visceral aneurysm caused by various reasons, and death caused by hemorrhage and shock. [0003] The treatment of aneurysms in modern clini...
