specific Embodiment approach 1

[0033] The personalized customized manufacturing pocket design method based on 3D printing technology of the present embodiment, such as figure 1 As shown, the method is realized through the following steps:

[0034] Step 1, obtaining CT scan data of the patient's abdominal artificial anus area;

[0035] Step 2. Based on the CT scan data, reconstruct the three-dimensional model of the artificial anostomy and surrounding skin;

[0036] Step 3. Preprocessing the reconstructed 3D model data, including: smoothing, removing noise and impurity points, and simplifying the model;

[0037] Then draw the contour curve of the stoma according to the graphics presented by the preprocessed three-dimensional model, and save the drawn contour curve as a file in iges format;

[0038] Step 4. According to the 3D model data of the stoma, design the silicone base model of the ostomy bag, including the film structure used to wrap the artificial anus and reflect the shape of the 3D model of the s...

specific Embodiment approach 2

[0044] The difference from the specific embodiment 1 is that, in the design method of the ostomy bag auxiliary cutting device based on 3D printing technology in this embodiment, in the second step, the process of reconstructing the three-dimensional model of the artificial anostomy and surrounding skin, Specifically: Based on the CT scan data, use the medical reconstruction software Mimics to reconstruct the three-dimensional model of the artificial anostomy and surrounding skin.

[0045] Operation process: 1. Import CT data into Mimics21 software in .dicom format;

[0046] 2. Use the Threshold command in the SEGMENT module in the Mimics21 software to segment the CT data, and use the Skin Tissue (CT, Adult) to extract the skin data;

[0047] 3. Reconstruct the 3D model of the extracted data and export it in .STL format.

specific Embodiment approach 3

[0049] Different from the second specific embodiment, the personalized ostomy bag design method based on 3D printing technology in this embodiment, in the third step, the preprocessing of the reconstructed three-dimensional model data is performed using the industrial design software GeomagicWrap The software performs further preprocessing on the reconstructed 3D model data.

[0050] 1. Import the reconstructed 3D model data into Geomagic Wrap software, first use the Trim command in Polygons to trim the model data, and only keep the stoma and its surrounding data;

[0051] 2. Use the Quicksmooth command to smooth the model data;

[0052] 3. Use the Offest command in the Polygons module to design the membrane structure with equal wall thickness along the stoma.

Abstract

The invention discloses an individualized customized pocket design method based on 3D printing technology and a product, and belongs to the field of medical auxiliary instrument design. The problem that an opening of an existing ostomy bag for an artificial anus is not accurate is solved. The individualized customized pocket design method based on 3D printing technology comprises the steps that onthe basis of CT scanning data of the artificial anus region of the abdomen of a patient, three-dimensional model reconstruction is performed on the stoma of the artificial anus and surrounding skin;the reconstructed three-dimensional model data is preprocessed; according to the three-dimensional data of the stoma, an ostomy bag skin-attached silica gel base model is designed, and the model is saved as a file of the stl format; the designed file is input into a 3D printer for entity printing manufacturing. The ostomy bag can meet the requirement for individualized customization of a patient,liquid leakage and air leakage are avoided, and meanwhile stoma external hernia is avoided due to a bellyband.

Description

technical field [0001] The invention belongs to a mold design method and product for 3D printing technology in clinical postoperative care of medical surgery, and specifically relates to a personalized customized manufacturing pocket design method and product based on 3D printing technology. Background technique [0002] An artificial anus, also known as an artificial anus, or an enterostomy. Refers to the diversion of stool through surgery for various reasons, no longer discharged from the anus, but discharged from the stoma of the abdomen. According to whether it can be retracted, it can be divided into permanent and temporary; according to different stoma sites, it can be divided into sigmoid colostomy, descending colostomy, transverse colostomy, ileostomy, jejunostomy, etc.; Separation is divided into single-lumen stoma and double-lumen stoma. In our country, about 100,000 people have enterostomy due to low rectal cancer every year, and the cumulative number of patient...
