Technical Problem

然而，硅凝胶假体存在以下显著缺陷：（1）破裂后渗漏风险：硅橡胶外壳在体内长期受反复挤压、弯折后可能发生疲劳破裂，一旦破裂，硅凝胶内容物可渗入周围组织，形成硅肉芽肿，难以彻底清除，给患者造成不可逆的组织损伤

Benefits of technology

[0016]This invention abandons the traditional approach of using liquid (saline) or semi-solid (silicone gel) filling cores in prostheses. Instead, it innovatively employs multiple independently encapsulated nickel-titanium alloy woven spheres as the core support structure, encased in a medical-grade silicone rubber elastomer shell. The superelasticity of the nickel-titanium alloy gives it flexibility and recoverable deformation capabilities comparable to human soft tissue at body temperature. The hollow nature of the woven structure significantly reduces the overall mass of the core compared to silicone gel of the same volume, fundamentally reducing the risk of gravitational sagging. The dispersed layout of multiple independent spheres avoids the overall rigidity of a single large core, ensuring a soft and natural feel. The solid metal woven core structure prevents liquid or semi-liquid contents from seeping into surrounding tissues even if the silicone rubber shell ruptures in extreme cases, and each woven sphere can be completely removed, achieving "safe and controllable after rupture." The weak paramagnetism of the nickel-titanium alloy (magnetic susceptibility far lower than medical stainless steel) ensures that postoperative MRI/CT imaging follow-up is not significantly interfered with.

Abstract

The application discloses a breast implant containing a nickel-titanium alloy braided inner core. It comprises a medical-grade silicone shell and a plurality of inner core spheres filled in the shell. Each inner core sphere is composed of a spherical braid woven by a nickel-titanium alloy wire and a silicone coating. The super-elasticity of the nickel-titanium alloy endows the implant with a compliance and a recoverable deformation capacity equivalent to those of human soft tissues. The hollow nature of the braided structure reduces the weight of the implant by 35-50% compared with a silicone gel prosthesis of the same volume, significantly reducing gravity sagging. The inner core is a solid braid, so there is no risk of content leakage after the shell breaks, and each sphere can be completely removed. The application realizes the comprehensive effects of soft feel, light weight and safe and controllable safety after breakage, and is suitable for breast reconstruction after mastectomy and breast augmentation surgery.
