Manufacturing method applied to manufacture 3D printing simulation board of funnel chest correction board

Abstract

The invention discloses a manufacturing method for manufacturing a 3D printing simulation board of a funnel chest correction board. The manufacturing method comprises the following steps: (a) a 3D thoracic cavity model for a funnel chest patient is established; and (b) the shape of the contour of a corrected thoracic cavity of the funnel chest patient is predicted so as to establish a 3D printingmodel of the corrected predicted thoracic cavity contour; (c) a postoperative thoracic cavity contour model is established according to the two models; (d) the implantation position of the funnel chest correction board is found through the postoperative thoracic cavity contour model, and a 3D printing model of a simulation board is established; and (e) the 3D printing model of the simulation boardis printed through a 3D printing device to obtain the 3D printing simulation board customized according to the shape of the thoracic cavity of an individual patient and the radian of the two sides ofthe thoracic cavity, thus a physician can manufacture the funnel chest correction board customized according to the shape of the thoracic cavity of the individual patient and the radian of the two sides of the thoracic cavity by taking the 3D printing simulation board as a template, the funnel chest correction board is precisely implanted in the correct position, turning over is conducted in place once, and the operation time is dramatically shortened.

Description

technical field [0001] The present invention relates to a manufacturing method of a simulation board for manufacturing a pectus excavatum correction board, in particular a 3D printing simulation for manufacturing a pectus excavatum correction board that is tailored for the chest shape of a pectus excavatum patient by means of 3D printing technology The method of manufacturing the board. Background technique [0002] The official medical name of the indentation of the thoracic cavity is Pectus excavatum, which is commonly known as funnel chest. Pectus excavatum is a congenital disease with a probability of 8 out of 1,000. In Taiwan, China, more than 600 newborns will have pectus excavatum within a year. The ratio of male to female is 4:1. The cause may be abnormal cartilage on both sides of the sternum. Hyperplasia, where the costal cartilage on the anterior chest wall grows too rapidly, causing compression that causes the anterior sternum to sink inward, reducing the distan...

Problems solved by technology

[0007] However, the commercially available simulation boards are not directly tailored to the shape of the patient's chest cavity, so there are some errors with the shape of the pectus excavatum patient's chest cavity, and it is impossible to provide a simulation board that is 100% suitable for all patients with pectus excavatum , so that the doctor may misjudge the situation, resulting in the selection of a simulation plate whose size is not suitable for patients with pectus excavatum, and then make a correction plate for pectus excavatum that is not suitable for patients with pectus excavatum

[0008] Furthermore, because the skin has a certain thickness, when the simulation plate is placed on the skin of the patient's chest, there may be errors to some extent, resulting in the subsequent production of the corrective plate for pectus pectus excavatum and the ribs, making it difficult for the doctor to place the funnel chest. The chest correction plate is fixed on the ribs of the patient with pectus pectus excavatum

[0009] In addition, the commercially available simulation boards are not directly tailored to the curvature of both sides of the patient's chest cavity, so there are some errors with the curvature of the chest cavity of patients with pectus excavatum. It fits closely with the ribs, making it difficult for doctors to fix the corrective plate on the ribs of patients with pectus excavatum
