Abstract

一种防破裂乳房假体。本发明特点是乳房假体的囊体为二层或以上的多层囊结构,囊体强度增强,抗挤压、耐摩擦能力大大提高,可有效防止囊体破裂;且一旦某层囊体破裂,另外的囊体仍起到包覆作用,从而防止囊内填充物溢出,避免对人体造成危害,乳房外形也不会发生变形现象。

Description

一种防破裂乳房假体
本发明涉及一种乳房假体,属于隆胸医用材料的改进。
现有的乳房假体均为单层囊结构,植入人体后一旦破裂,囊内的液体或胶体将会溢出,不但造成假体失效、乳房外表变形,还会给人体带来危害。
本发明的目的在于提供一种可有效防止囊体破裂、避免囊体破裂对人体造成危害的乳房假体。
本发明如图1所示,包括有密闭中空的囊体(1),其特点是该囊体(1)为二层或二层以上的多层囊结构。
上述多层囊之间可以是一层层紧贴包覆,也可以是每层囊之间有一定间隙,内充有生理盐水、油类、硅凝胶或其他填充物。
本发明的乳房假体可以做成封闭式结构,囊体(1)内及多层囊各层之间预先充有生理盐水、硅胶或其他填充物。也可以是注入式结构,此时囊体(1)设置有单向阀(2),如图2所示。本发明的乳房假体植入人体的方法与传统的相同。
本发明另外一种表现形式如图3所示,囊体(1)为单层囊或多层囊结构,囊体(1)内填有许多包容有填充物的小囊体(3),小囊体内填充物为生理盐水、油类、硅凝胶或其他填充物,均做成封闭式结构。这种乳房假体的多层囊结构由整体的大囊体(1)和各小囊体(3)组成,能较好的分散外界作用力,有效防止囊体破裂。这种乳房假体可做成封闭式结构,或填入式结构,前一种结构,小囊体(3)预先置入囊体(1)内密封成一整体;后一种结构,囊体(1)设置有开口,开口处设有封盖(4),手术使用时,可先将中空的囊体(1)植入人体,然后将小囊体(3)从开口处逐个填入,填满后用封盖(4)粘接将囊体密封。填入式结构形式手术填入较为方便,有利于简化手术操作,缩短手术时间。
本发明由于采用多层囊结构,囊体强度增强,抗挤压、耐磨擦能力大大提高,可有效防止囊体破裂;且一旦某层囊体破裂,另外的囊体仍起到包覆作用,从而防止囊内填充物溢出,避免对人体造成危害,乳房外形也不会发生变形现象。
图1为本发明结构示意图;
图2为多层囊体结构的注入式乳房假体示意图;
图3为由小囊体组成多层囊体结构的乳房假体示意图。
实施例:本例如图2所示,囊体(1)为三层囊结构,各层之间涂覆有少许油类起润滑作用。多层囊采用硅橡胶材料制成;囊体(1)为注入式结构,设置有单向阀(2),各层囊在此处粘接在一起,且开有对应单向阀(2)入口的开口,单向阀为两片薄膜组成的片阀,使用时用导管穿过两片薄膜与内腔相通,即可向内注入生理盐水等填充物,填充完毕抽出导管,片阀的两片薄膜会自动贴合封口,然后将片阀弯折向一边即可。
