Abstract

The invention discloses a heart valve model and a manufacturing method thereof, and relates to the technical field of medical instruments.The manufacturing method comprises the steps that medical image data of a heart valve of a specified patient is acquired, and a digital model of the heart valve is constructed based on the medical image data; the contour of the digital model is evenly expanded outwards by a preset thickness, after an expanded model is obtained, Boolean subtraction is carried out on the digital model and the expanded model, a hollow mold model is obtained, and the mold model is provided with a pouring inlet and an exhaust port; the mold model is guided into a 3D printer, a soluble material is adopted for printing, and a heart valve mold is obtained; and preparing a simulation material, pouring the simulation material into the heart valve mold, and dissolving the heart valve mold after the simulation material is cured to obtain the heart valve simulation model. According to the manufacturing method, individualized pathological anatomy reproduction can be achieved, and the heart valve simulation model manufactured through the method can serve as a simulation model for preoperative operation simulation and operation training of clinicians.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a heart valve model and a manufacturing method thereof. Background technique [0002] Currently, valvular heart disease is one of the most common cardiovascular diseases, often requiring surgical intervention. With the continuous development of medical technology and equipment, the treatment methods for heart valve diseases are also constantly updated. The surgical approach ranges from transthoracic, transthoracoscopic to transcatheter treatment, and the surgical methods range from valve replacement to valvuloplasty. Therefore, it is particularly important to conduct a detailed preoperative assessment of the pathological anatomy of different patients, select the appropriate surgical path, and formulate the best surgical plan. In addition, the choice of surgical plan is closely related to the clinical experience of the operator. For cardiovascular specialists of...
