Example Embodiment

[0019] Embodiment one

[0020] Take the leg bone CT scan data as an example, obtain the patient's leg bone CT scan data, get the image in DICOM format, and import the DICOM data into Mimics17.0. Mimics 17.0 will read in CT scan data, as well as parameters such as height and layers. In the process of importing data, select the viewing angle of the image, and perform threshold segmentation on the image. Set the threshold range of the leg bone between 95hu and 1813hu. Adjust the threshold point to obtain the tissue contours of different bone parts. When the threshold point is low, the bone will be selected. Then mark the parts of interest, because the data contains too much redundant data, we need to select the image according to the demand, reduce the amount of data processing and the impact of redundant data on model generation. Then the image is ablated, and the marked area is ablated by 2 pixels, and the marked part and redundant data are further separated. Then export the...

Abstract

The invention discloses a method of three-dimensionally printing a customized protector. The method includes the steps of that an affected part image of a patient is obtained through CT scanning; data of the affected part image of the patient is input into model processing software to generate a three-dimensional model; the generated three-dimensional model is input into model repairing software to conduct grid repairing, and a corresponding protector model is set up; segmentation processing is carried out on the protector model; all three-dimensional models obtained after segmentation are input into slice software to conduct slice processing, and a printing file containing printing information is generated; the printing file is input into a 3D printer to conduct printing, and the segmentation model of the protector model is obtained; all the segmentation models are assembled and punched. According to the any forming characteristic of the three-dimensional printing technology, the requirement for individual manufacturing the bone fracture protector, namely the individual gypsum protector can be printed three-dimensionally so that the protector can be completely matched with the affected part of the patient, the workload of medical workers is reduced, and discomfort caused by unmatched protector during patient recovery is reduced.

Description

technical field [0001] The invention relates to a method for three-dimensional printing customized protective gear, which belongs to the technical field of 3D printing and medical rehabilitation. Background technique [0002] Traditional methods of external fixation of protective gear include small splints, plaster bandages, abduction frames, continuous traction, and needle external fixators. Because the traditional plaster cast bandage fixation method is complicated to operate, it increases the workload of medical staff, and the patient experience is not very good. In addition, different patients have differences in their own body structures, and the traditional fixation method may not be suitable for some special cases, which may result in a longer recovery period for patients. Therefore, it is necessary to make personalized protective gear according to the physical characteristics of the patient. Contents of the invention [0003] The technical problem to be solved by...
