Problems solved by technology

However, no similar products or research reports have been seen at home and abroad, so it is necessary to establish a design and preparation method for a simulated human body model that can truly simulate the soft tissue of the face of a child for the first time.

Embodiment Construction

[0029] The preparation method steps of baby cleft lip simulation face model of the present invention are as follows:

[0030] 1) Acquisition of 3D original face data of children with cleft lip: This invention adopts the 3DSS-STD-II structured light human body 3D scanning system (Shanghai Shuzao Electromechanical Technology Co., Ltd.) to realize the collection of living body data of children's faces. The main performance indicators of the equipment: single Frame measurement range (mm): 400×300; Single frame measurement points: 1.3 million; Design measurement accuracy: 0.03mm. Before operation, turn on the 3DSS-STD-II structured light three-dimensional scanning system, adjust the height, angle, and position of the scanner, adjust the focal length, and aperture of the camera, so that the obtained image is clear and bright, and the system parameters are adjusted as follows: base distance = 500mm; measurement Distance ≈900mm; α≈30°. Camera focal length = 16mm. Adjust the height a...

Abstract

The invention belongs to the design of a surface model of a medical simulation human organ and a preparation method, in particular to a preparation method for an infant cleft lip facial simulation model, which comprises the following steps: (1) collecting three-dimensional original data of faces of cleft lip illness children; (2) rebuilding digital facial models of the faces of the cleft lip illness children; (3) automatically layering and scattering model files and forming processing files; (4) automatically processing resin part models of the faces of the cleft lip illness children; (5) duplicating silastic cleft lip facial models; and (6) coloring the silastic facial models. The invention can provide a personalized customization facial simulation model which is in high consistence withthe shape, color, texture and the like of the faces of the cleft lip illness children with three age of months; the simulation model not only provides the real reference for a surgeon before operation, causes the surgeon to know fairly well during the operation, and simultaneously provides postoperative facial esthetic effects for parents of cleft lip and palate patients.

Description

technical field [0001] The invention belongs to a design and preparation method of a simulated human organ surface model for medical use, and in particular relates to a preparation method of a baby's cleft lip face simulation model. Background technique [0002] Cleft lip and palate is one of the most common congenital maxillofacial defects. The incidence rate in China accounts for about 7% of the birth rate. According to statistics, there are at least 2.4 million patients with cleft lip and palate in my country, and there are more than 20,000 people every year. A newborn with cleft lip and palate was born. Cleft lip repair surgery at the age of 3 months is the main treatment for cleft lip at present. Tens of thousands of children with cleft lip undergo surgical treatment every year in China, so a large number of surgeons who are skilled in this operation are needed, but domestic and foreign There is no highly realistic medical model of infant cleft lip on the market for you...
