Background technique

Scoliosis is a kind of three-dimensional deformity of backbone and rib cage.In many partings of scoliosis, adolescent idiopathic ridge Column lateral bending (Adolescent idiopathic scoliosis, AIS) is the most common type, since pubertal growth is rapid, If falling ill nonintervention treatment in this period, lateral bending usually quickly grows, causes to seriously endanger to teen-age physical and mental health. Clinically usually with the angle Cobbe, (vertical line of head side vertebra upper limb and the angle of cut of caudal end vertebra lower edge vertical line are the angle Cobb；If Hold the upper and lower edge of vertebra unclear, can use the line of the upper and lower edge of its pedicle of vertebral arch, then taking the angle of cut of its vertical line is the angle Cobb) it comments Estimate the severity of AIS, if lateral bending develops to moderate (angle<45 ° 20 °<Cobbe), selects Brace Treatment, the angle Cobbe> Operative treatment is just considered at 45 °, but operative treatment has the shortcomings that somewhat expensive, risk are big, postoperative complications are more.Fig. 4 is ridge Column lateral bending early stage lopsided appearance diagram.

Brace Treatment can effectively reduce high risk lateral bending curve and aggravate to need the ratio of operative treatment, in order to effective Prevention lateral bending progress, daily type brace at least needs to dress 20 hours or more daily, and night using type brace is also required to night wearing 8 Hour, but wearing will lead to pain in back and loin, lumbodorsal muscle atrophy, decline in pulmonary function, skin compression ulcer and allergy for a long time Etc. complication, the quality of life of patient is affected greatly, so as to cause compliance decline, and good compliance can be reduced Curve is in progress and needs operative treatment risk, therefore makes comfortable, light, ventilative brace and seem especially heavy to promote compliance It wants, compliance difference is the main problem during Brace Treatment.Early stage, there are many scholars to the therapeutic effect of different braces It being studied, Roaf etc. uses Milwaukee Brace Treatment AIS using Boston Brace Treatment AIS, Lonstein etc., Price etc. has carried out the research of Charleston brace；The Providence brace observation of curative effect of Janicki etc., as the result is shown Curative effect it is although variant, but prove brace can effectively treat AIS.If different Brace Treatment difference on effect is little, It should select to the smallest brace of Quality of Life.

Night using type brace is mainly dressed in sleep, to the Quality of Life very little of patient, different treatment concepts Wear time is shortened, to effectively improve compliance, but since the price of night using type brace is higher, is difficult at home general And so the new manufacture craft found further promotes the direction that curative effect is development to reduce expense simultaneously.Domestic branch at present The production of tool is based on the production of traditional-handwork modulus, the disadvantages such as it is cumbersome that there is processes, and precision is low, in comfort, cost and system Make in efficiency there are also very big room for improvement, digitize in recent years computer aided design (Computer aided design, CAD) and 3D printing technique is gradually risen in the application of orthopaedics, the new developing direction of brace designed and produced.

The defect of CAD/CAM production:

1. the data that measurement modulus needs to measure are more, there is large errors, are then introduced into computer design brace model, There are certain subjectivities, so the model accuracy of production is still limited.

2. domestic based on the production of manual modulus, CAD/CAM production foreign applications are more, and transnational fabrication cycle is long, expense It is high.

3. poor air permeability is easy to appear complication, compliance is caused to decline.

The defect of the daily type brace (by taking CN205339234U as an example) of 3D printing:

1. only increasing several indent stress points inside brace, the release problem of pressure is not accounted for, mechanics factor is examined Consider single, orthopedic effect is extremely limited.

2. pressure nowhere discharges when putting on brace and tightening, trunk is caused integrally to be tightened, to influence to breathe, and volume Larger, influence activity on daytime, comfort is extremely limited.

3. the design of front side band is unreasonable, different installation site and side are not considered according to the case where different patients To not can guarantee the accurate application of power, orthopedic effect is limited.
