Description
Technical field
This utility model relates to surgical plastic technical field, in particular, relates to a kind of nose prosthesis.
Background technology
Do augmentation rhinoplasty operation to need to use nose prosthesis, need by the postoperative effect of computer simulation before the surgery, then the original nose prosthesis that mates most according to this effect selection shape of doctor, and the postoperative effect of contrast expection, with scalpel, secondary operations is carried out to nose prosthesis, finally obtain personalized nose prosthesis.Because manual cutting precision is poor, cause nose prosthesis to be followed between the bridge of the nose and there is larger gap, laminating degree is poor, affects post-operative recovery, even causes nose prosthesis to come off.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of nose prosthesis improving nose prosthesis laminating degree.
The purpose of this utility model is achieved through the following technical solutions:
A kind of nose prosthesis, comprises nose, nose pillar, the bridge of the nose, and the bridge of the nose connects nose pillar by nose, and the described bridge of the nose comprises top layer for shaping and the laminating layer for fitting with nose, and the hardness of described laminating layer is lower than top layer.
Further, described laminating layer and top layer adopt same material to make, and described laminating layer has hole.Laminating layer arranges a large amount of holes, originally and the harder laminating layer of the same material in top layer just become soft, and there is elasticity, can stretch, can well to fit nose, there is hole that body fluid flow can be allowed to enter hole and grow tissue, nose is allowed to be connected with nose prosthesis, prevent nose prosthesis from moving, come off, fester, prevent the pain of postoperative patient, nose prosthesis be taken out, can stretch because nose prosthesis has elasticity, easily the tissue in hole can be taken out, reduce operating difficulty, alleviate surgical damage.
Further, described laminating layer and top layer adopt same material to make, and described laminating layer and top layer all have hole, and the aperture density of laminating layer equals the aperture density on top layer, at nose prosthesis same thickness layer region, the hole depth of laminating layer is greater than the hole depth on top layer.The aperture density on laminating layer, top layer is identical, and the hole depth of laminating layer is greater than top layer hole depth, and laminating layer is softer than top layer, and laminating layer can well be fitted nose.Top layer has hole formation dull surface, and transparency, reflectance reduce, close with normal nose, more natural, and top layer have a lot of hole after flexible, similar to human body skin, more naturally, true to nature, top layer is harder than laminating layer, can play reasonable fixed effect.
Further, described laminating layer and top layer adopt same material to make, and described laminating layer and top layer all have hole, and the aperture density of laminating layer is greater than the density of top layer hole; And at nose prosthesis same thickness layer region, the hole depth of laminating layer equals the hole depth on top layer.
The hole depth on laminating layer, top layer is identical, the aperture density of laminating layer is greater than the density of top layer hole, top layer has darker hole can be allowed body fluid flow enter in hole to be connected with nose prosthesis, strengthen its stationarity, prevent nose prosthesis from moving, top layer is harder than laminating layer, can play reasonable fixed effect.
Further, described laminating layer and top layer all have hole, and laminating layer aperture density is greater than top layer aperture density, and at bridge of the nose same thickness layer region, laminating layer hole depth is greater than top layer hole depth.
Top layer has hole can be allowed body fluid flow enter in hole to be connected with nose prosthesis, strengthen its stationarity, prevent nose prosthesis from moving, and after there is a lot of hole on top layer, top layer is light tight is a dull surface, identical with normal nose, and top layer have a lot of hole after flexible, similar to human body skin, more naturally true to nature, top layer is harder than laminating layer, can play reasonable fixed effect.
Further, hole is blind hole, and the bottom of hole is plane.Hole laser is up to, the hole that laser equipment is got, its hole periphery is mellow and full, and bottom is a plane, impulse-free robustness, hole queueing discipline, the spacing between Kong Yukong is identical, and entirety is very attractive in appearance, also can control size and the degree of depth of hole as required, perforation, blind hole freely control, and degree of accuracy very, provides the precision to nose prosthesis engraving greatly.
Further, described nose prosthesis edge is jagged.During the punching of bridge of the nose edge, marginal portion is not enough to beat complete opening, then edge is an incomplete circle, and the elasticity at edge is better, can better remove nose of fitting, and tissue can be taken out when taking out nose prosthesis once stretching, simply very convenient.
Further, described nose is used for following the internal layer hardness of nose laminating lower than skin.Nose comprises the internal layer and skin of fitting with nose, internal layer has hole skin not have hole, or internal layer has darker or closeer or more deeply and closeer hole than skin, internal layer is flexible after having hole, can stretch, can well to fit nose, having hole that body fluid flow can be allowed to enter in hole allows nose be connected with nose, prevent nose prosthesis from moving, take out nose prosthesis, can stretch because nose has elasticity, can easily the tissue in hole be taken out, reduce operating difficulty, alleviate surgical damage.Skin is flexible after having hole, similar to human body skin, more naturally true to nature.
Further, the hardness of laminating layer material is lower than the hardness of skin-material; Described laminating layer and top layer are spliced to form the described bridge of the nose.Bridge of the nose laminating layer adopts soft material as soft silica gel, and top layer adopts hard material as hard silica gel.Such laminating layer is just soft than top layer, the soft nose of can well fitting of laminating layer, top layer firmly then can obtain good fixed effect, both materials are delivery respectively, then be superimposed upon once through modes such as hot pressing, one-shot forming, top layer and laminating layer can need random combination according to client, use more flexible, the scope of application is wider.
Further, the hardness of described nose material is lower than the hardness of the bridge of the nose and nose pillar.Nose adopts softer material can have good elasticity, more naturally true to nature.
This utility model is because laminating layer hardness is lower than top layer, easilier shape can be adjusted according to nose profile with after nose laminating, fill up with bridge of the nose gap, even if machining accuracy is not high, laminating layer also effectively can be fitted with nose, doctor simply carves, even just directly can use without the need to engraving, save a lot of work, improve efficiency, and reduce the requirement of engraving technical ability, be conducive to reducing operating difficulty and cost.And the top layer material of nose prosthesis is comparatively hard, available moulding well, guarantee that nose type is stablized, be not easy depression injustice.Therefore, this utility model while raising laminating degree, can guarantee postoperative effect.
