Problems solved by technology

The patient is more painful in the process of taking the film, and the level of technicians is different in the process of pouring the mold, which is prone to relatively large errors, which makes the pressure mask produced not only unable to be personalized and fit, but also leads to uneven pressure in local areas. Uniform, can not achieve the expected effect, not conducive to the rehabilitation of scars
Due to the complexity of the existing manufacturing process, professionals who can master this technology are even rarer.
At present, only a few large hospitals in China can carry out the production technology of pressure masks

Embodiment 1

[0036] A digital design and 3D printing preparation method of a personalized pressure mask, such as figure 1 shown, including the following steps,

[0037] Step 1, scan the object to obtain point cloud data. Step 1 is specifically to scan the exposed skin in front of the target subject's head and above the neck with a handheld laser three-dimensional scanner to obtain point cloud data.

[0038] Step 2: Import the acquired point cloud data into GEOMAGIC STUDIO software to digitally design the initial 3D mask body model, and save the 3D mask initial body model as an STL format file.

[0039] Step 2 specifically includes the following steps,

[0040] Step 2-1, modify the point cloud data in GEOMAGIC STUDIO software to construct a complete facial skin outline;

[0041] Step 2-2, in the GEOMAGIC STUDIO software, perform data processing and encapsulation on the facial skin contour constructed in step 2-1, thicken the triangular piece of the skin contour surface of the extracted s...

Embodiment 2

[0059] A digital design and 3D printing preparation method of a personalized pressure mask, such as figure 1 , figure 2 shown, including the following steps,

[0060] (1) Data collection

[0061] Use the hand-held 3D scanner to scan all the exposed skin on the front of the subject’s head and neck, follow the prompts of the scanning supporting software to obtain complete point cloud data, and instruct the patient to keep the required fixation according to the treatment plan of the rehabilitation subject location, collecting complete and comprehensive point cloud data.

[0062] (2) Data processing

[0063] Import the scanned point cloud data file into the reverse engineering software GEOMAGIC STUDIO for data processing and encapsulation, extract the skin contour surface triangle of the scanned part for outward thickening, generate a shell-like 3D model, and save it as an STL format file and export it to the MAGIC software for further processing Repair processing.

Abstract

The invention provides a digital design and 3D printing method for a personalized pressure mask. The method comprises the steps of 1, operating to acquire point cloud data; 2, importing the point cloud data into digital design to acquire a preliminary three-dimensional mask model; 3, importing an STL format file of the three-dimensional mask preliminary mode into 3-MATIC software for repairing, then performing digital design in GEOMAGIC STUDIO software to acquire a finished three-dimensional mask model, and storing as the STL format file; 4, importing the STL format file of the finished three-dimensional mask model into MAGIC software to perform digital design and well adjusting a printing parameter; and 5, copying the file of the mask model to be printed into a 3D printer for printing to acquire the personalized pressure mask. The method provided by the invention is safe in data collection, quick in speed and simple in design process; the printed pressure mask is portable, high in matching degree with a user and good in effect.

Description

technical field [0001] The invention relates to the technical field of medical devices for facial treatment in the rehabilitation department, in particular to a digital design and 3D printing preparation method of a personalized pressure mask. Background technique [0002] Facial scar is a common clinical symptom, which can be caused by facial burns, failed plastic surgery, traffic accidents, etc. The treatment generally adopts conservative treatment or surgical skin grafting. The timing of conservative treatment is generally within half a year of scar formation. Wearing a pressure mask for local pressure and external application of scar softening drugs can reduce the formation of scars. Surgical treatment is performed after the scars are mature and stable, and drug treatment is ineffective. Just choose. Pressure masks are very important for the treatment of scars. If the custom-made pressure masks are not suitable and the treatment measures are not handled well, it will of...
