Abstract
The present invention relates to the digitalized preparation of artificial implant for personalized nasal plastics. Based on the facial contour data of the individual patient and through the visible simulation of post-operation effect, the digital mold of the implant is obtained directly and different precise purpose made nasal implants are used for individual patients. During the implantation, few artificial carving is needed, and this can shorten greatly the operation time, reduce patient's pain and meet the expectation of patients at most.
Description
Technical field
The present invention relates to the preparation method of facial nose shaping artificial implant, particularly a kind of digitizing preparation method who digital technology is used for personalized nose shaping artificial implant.
Background technology
Nose shaping artificial implant is one of cosmetic plastic surgery body implanting material the most commonly used, generally is used to improve the beauty treatment of nose profile, and the corrective procedure of the nose depressed deformity that causes because of wound, infection, tumour and congenital factor.
At present, the main nose shaping implant that adopts has following several:
1, molding silicone rubber artificial nose cosmetic prosthesis: be the nose shaping implant that is most widely used at present,
2, molding of polyethylene artificial nose cosmetic prosthesis: produce by U.S. POREX company.Adopt fixedly that model designs, and its product appearance and Chinese patient have than big-difference also.Involve great expense, for present surgery cost 5 times often are difficult to bear for Chinese patient.Owing to adopt polythene material to make, the big and elasticity deficiency of hardness.
3, from the body costal cartilage: cut patient self or allosome costal cartilage, be shaped through engraving, pruning.Owing to need the excision costal cartilage, cause additional injuries with painful to the patient, and material source is limited, absorption distortion is to a certain degree arranged long term.
In addition, adopt the methods such as xenogenesis cartilage after processing is handled that report is also arranged, very few the employing owing to occur problem such as immune response and distortion easily.
The common drawback that said method exists is:
No matter whether 1 be molded product, each patient's nose anatomic form that all can not meet fully, thereby need surgical doctor in art, to carry out further concrete processing engraving according to patient's actual conditions; Can not realize the personalization preparation of implant.
2, can't predict the shape and the surgical effect of implant before patient's art in advance, surgical outcome depends on the height of doctor's aesthetic conceptions and engraving skill fully, is difficult to satisfy patient's individual demand.
3, owing to need to carve in the art, operating time is longer.
4, because the inside surface of the nose shaping implant of doctor's engraving is difficult to fit like a glove with the anatomic form of implanting level, postoperative might cause the implant displacement because of maintenance is bad, influences surgical effect or causes second operation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and defective, adopt advanced digital technology, the digitizing preparation method of personalized nose shaping artificial implant of the profile effect of the facial anatomic form of a kind of patient of meeting and patient's expectation is provided.
