Embodiment 1

[0032] By operating the Sense hand-held body scanner 3D scanner (1) of 3D systems, the patient needs to be corrected, that is, the limb to be scanned (2) is scanned in 3D, and the 3D scan data of the patient's leg to be corrected (3) is obtained by scanning ,Such as figure 1 shown.

[0033] By using computer software (Magics software from Materialize Company) to process (8) the scanned body data, such as figure 2 As shown in Fig. 1, perform operations such as shape repair and shape correction on the limbs to be orthoticed to obtain a three-dimensional model of the ankle-foot orthosis (9).

[0034] Input the three-dimensional model of the ankle-foot-orthosis into the three-dimensional printer, and produce (14) through the three-dimensional printer to obtain the ankle-foot-orthosis product (15), such as image 3 shown. Using the SLS laser sintering printer of EOS company, the nylon powder material is used for production. The surface of the heated raw material powder layer i...

Embodiment 2

[0036] By operating the Sense hand-held body scanner 3D scanner (1) of 3D systems company, a 3D scan is performed on the part of the patient to be orthopedic, that is, the limb to be scanned (2), and the 3D scanning data of the patient's arm (4) to be orthopedic is obtained from the scan. Such as figure 1 shown.

[0037] By using computer software (Magics software from Materialize Company) to process (8) the scanned body data, such as figure 2 As shown in Fig. 1, perform operations such as shape repair and shape correction on the limbs that need to be orthoticed, and obtain a three-dimensional model of the inner shell of the arm orthosis (10).

[0038] Input the 3D model of the inner shell of the arm orthosis into the 3D printer, and produce (14) through the 3D printer to obtain the inner shell (16) of the arm orthosis product, such as image 3 shown. The light-curing rapid prototyping printer of SHINING 3D is used for production with photosensitive resin materials. The s...

Embodiment 3

[0040] By operating the Sense hand-held body scanner 3D scanner (1) of 3D systems company, a 3D scan is performed on the patient’s body to be corrected (2), and the 3D scan data of the patient’s torso (5) to be corrected is obtained from the scan. Such as figure 1 shown.

[0041] By using computer software (Magics software from Materialize Company) to process (8) the scanned body data, such as figure 2 As shown in Fig. 1, perform operations such as shape repair and shape correction on the limbs to be corrected, and obtain a three-dimensional model of the inner shell of the lumbosacral orthosis (11).

[0042] Input the 3D model of the inner shell of the lumbosacral orthosis into the 3D printer, and produce (14) through the 3D printer to obtain the inner shell of the lumbosacral orthosis (17), such as image 3 shown. The light-curing rapid prototyping printer of SHINING 3D is used for production with photosensitive resin materials. The solidified block is formed by laser sc...

Abstract

The invention discloses a three-dimensional printing preparation method for orthoses. The method is based on three-dimensional scanning, virtual restoration and three-dimensional printing techniques. The production periods of conventional orthoses are long, the orthopedic effect of the conventional orthoses is common, the manpower cost is high, and the conventional orthoses are highly inconvenient for patients. The method disclosed by the invention first utilizes a three-dimensional scanning device to scan a part to be corrected and record the three-dimensional scanned data of the part to be corrected; three-dimensional software is then utilized to carry out data processing on the three-dimensional model obtained by scanning, so that a digital three-dimensional orthosis model with an orthopedic function is obtained; finally, the digital three-dimensional orthosis model is printed by the three-dimensional printing process. The method solves the problem of complex shaping and shape correction by means of the three-dimensional scanning technique; the three-dimensional software is used for digitalized correction and restoration, so that the correction process is quantitative and accurate; since the three-dimensional printing production method is adopted, materials are diversified, and the production speed is high. Because three-dimensional digitalized operation is adopted by the whole process, the scheme dispenses with the vast majority of manual processing work, and therefore the cost is low.

Description

technical field [0001] The invention relates to three-dimensional printing technology, in particular to a method for preparing an orthosis based on three-dimensional scanning, digital restoration and three-dimensional printing technologies. Background technique [0002] Orthosis refers to the general term for external devices assembled on the limbs and trunk of the human body. Its purpose is to prevent or correct deformities of limbs and trunk or to treat bone joint and neuromuscular diseases and compensate their functions. Its functions mainly include the following aspects: [0003] (1) Stabilization and support: maintain joint stability and restore weight-bearing or exercise capacity by limiting abnormal movements of the limbs or trunk. [0004] (2) Fixation and correction: For deformed limbs or trunks, the deformity is corrected or the aggravation of the deformity is prevented by fixing the lesion. [0005] (3) Protection and load-free: by fixing the diseased limbs or j...
