Embodiment 1

[0034] figure 1 It is a flow chart showing a method for manufacturing a computer-aided Achilles tendon brace according to the first embodiment of the present invention. available in as Figure 7 The apparatus shown performs the method.

[0035] refer to figure 1 , in step S110 , acquiring the three-dimensional point cloud data and two-dimensional image data of the patient's limb.

[0036] Here, the point data collection of the appearance surface of the scanned object obtained by the measuring instrument is called point cloud data, and the 3D point cloud data is the point data collection of the appearance surface of the scanned object obtained by image acquisition equipment such as 3D LiDAR. In this embodiment, the scanning object is a patient's limb. The 3D point cloud data stores the 3D coordinates XYZ of the scanned object.

[0037] The embodiment of the present invention applies the three-dimensional point cloud processing technology to the field of brace manufacturing...

Abstract

The embodiment of the invention provides a computer-aided Achilles tendon brace manufacturing method and device. The method comprises the following steps that three-dimensional point cloud data and two-dimensional image data of patient's limbs are acquired; a three-dimensional model of the patient's limbs is generated according to the three-dimensional point cloud data; the two-dimensional image data is mapped into the three-dimensional model according to a corresponding relationship between the three-dimensional point cloud data and the two-dimensional image data; the mapped three-dimensional model conducts segmentation process to obtain a three-dimensional upper brace model and a three-dimensional lower brace model; and a 3D printing device is controlled to print the three-dimensional upper brace model and the three-dimensional lower brace model to manufacture an Achilles tendon brace, wherein the Achilles tendon brace comprises an upper brace support and a lower brace support. According to the embodiment of the computer-aided Achilles tendon brace manufacturing method and device, the manufacturing of the Achilles tendon which is individually customized and more comfortable is achieved, and the precision of the brace manufacturing is improved.

Description

technical field [0001] The invention relates to computer vision technology, in particular to a computer-aided method and device for manufacturing an Achilles tendon brace. Background technique [0002] For ankle fractures, fractures of the lower tibia and fibula, and ankle ligament injuries postoperative patients can use cast external fixation. However, the plaster adheres poorly to the skin and is less comfortable to wear, making it very painful for the patient. In addition, the hardness of the plaster is large, which is not conducive to functional rehabilitation in the later stage, and if proper functional training is not carried out in the later stage, the muscle strength of the affected limb will be severely weakened, and the range of motion of the joint will also be reduced. [0003] A good brace is important for patients to restore normal function. 3D printing technology has the advantages of low price of equipment and materials, high precision, wide selection of mat...
