Embodiment 1

[0038] The concrete steps of the manufacture method of pectus excavatum orthopedic device 1 of the present invention are as follows:

[0039] Scan the patient's chest with MRI imaging equipment (SignaEXCITE0.35T) to obtain DICOM pictures of the chest shape, use high-performance graphics processing server (FFmpeg) and medical-specific 3D software for data processing, realize 3D reconstruction of DICOM pictures, and convert the patient's chest shape into 3D The digital model measures the three-dimensional data of the patient's pectus excavatum, including parameters such as the length, width, and depth of the sternal depression, and calculates the thoracic Haller index and pectus excavatum index based on the parameters, and understands the patient's pectus pectus excavatum under the guidance of clinical and professional doctors. Morphology and clinical grading, and then through the self-developed three-dimensional software to design an individualized orthopedic device that perfect...

Embodiment 2-5

[0041] Except scanning the chest of different patients, to obtain the DICOM picture of the thorax shape of different shapes, obtain pectus pectus orthopedic device 1-5 in the same manner as embodiment 1 (see respectively Figure 2-5 ).

Abstract

The invention provides a funnel chest orthotics device and a manufacturing method thereof.The funnel chest orthotics device comprises an orthotics plate and a fixed piece, and is made from titanium alloy including, by weight, smaller than or equal to 0.30% of iron, smaller than or equal to 0.10% of carbon, smaller than or equal to 0.05% of nitrogen, smaller than or equal to 0.015% of hydrogen, 1.0-1.4% of oxygen, 6.9-7.5% of aluminum, 2.5-3.4% of vanadium and the balance titanium.The funnel chest orthotics device can be used for symmetrical or asymmetrical chests and can also be used for flat chests.The specific titanium alloy material with good biological compatibility is adopted, the toxicity to human bodies is avoided, weight is reduced, and the tolerance of patient is improved.

Description

technical field [0001] The invention relates to an orthopedic medical device, in particular to an implanted device for treating pectus pectus excavatum in thoracic surgery and a manufacturing method thereof. Background technique [0002] Pectus excavatum is a common congenital thoracic deformity. The treatment of pectus pectus excavatum is the internationally accepted minimally invasive pectus excavatum correction, namely Nuss operation. The straight strip-shaped orthopedic plate made of stainless steel is used in the operation. Manufactured industrially on a large scale, with a uniform shape. During the operation, the doctor needs to manually bend the device according to the actual situation of the patient, and visually observe the correction effect. It cannot achieve digital and precise shaping, and can only achieve the requirements of appearance plastic surgery and postoperative recovery effect based on experience. Secondly, for some special types of pectus excavatum, su...
