Breast implant

Abstract

The invention discloses a breast implant. The breast implant comprises a flexible bag body and a filling material accommodated in the bag body, wherein the bag body comprises a tidy back surface and a front surface protruding in a direction far from the back surface; the projection of the bag body on the plane of the back surface has a first endpoint and a second endpoint; a longitudinal axial line is defined by the first endpoint and the second endpoint; the projection of the bag body on the plane of the back surface is symmetrical relative to the longitudinal axial line; the length of the projection on the longitudinal axial line is longer than that of the projection in a direction perpendicular to the longitudinal axial line; the external profile of the projection of the bag body has a first arc passing through the first endpoint and a second arc passing through the second endpoint; the radius of the first arc is smaller than that of the second arc; and when an observer observes from the front surface of the bag body in a direction perpendicular to the back surface of the bag body, at least one skirt edge is connected with the outer edge of the bag body which is only positioned on one side of the first endpoint. The breast implant provided by the invention satisfies the dressing habits of modern women, as well as can achieve a vivid and attractive shaping effect.

Description

technical field [0001] The invention relates to an implantable prosthesis, in particular to a breast prosthesis which can be implanted into body tissue to shape the breast. Background technique [0002] Implantable prostheses are generally used to replace or augment body tissue. For example, for patients with small breasts, mild breast sagging and breast defects, breast prostheses such as silicone gel breast prosthesis can be implanted in body tissues to support surrounding tissues to maintain body appearance. Capsular contracture is one of the most common complications after breast implant surgery. This complication will make the breast implant become spherical and stiff, leading to symptoms such as breast hardening, pain, and breast asymmetry. It will cause the capsule of the breast prosthesis to rupture, and the silicone gel filled in the capsule will leak out and induce breast cancer. [0003] In order to solve the problems of prosthesis displacement, deformation and c...

Problems solved by technology

However, viewed from the front of the breast prosthesis, the breast prosthesis appears to be a perfect circle, so the shape of the breast prosthesis is still quite different from that of the natural breast, and the plastic surgery effect is not good

[0010] Finally, among the four positioning points on the capsule of the breast prosthesis, three positioning points are set on the back of the capsule, and one positioning point is set on the lower part of the front of the capsule. The breast prosthesis can be accurately positioned, but after the breast prosthesis is implanted into the body tissue during the operation, the positioning point on the back of the capsule cannot be captured by the doctor, while the positioning point on the front of the capsule is located at the center of the capsule. The lower part, the patient is lying flat during the plastic surgery, it is not easy for the doctor to touch the positioning points on the front and lower part of the capsule with fingers during the operation, resulting in inconvenient or even inaccurate positioning

At the same time, since the breast is usually touched from the lower part or both sides close to the lower part, it is easy to feel the positioning points set on the front and lower part of the capsule when touching the breast, which reduces the authenticity and beauty of the breast after plastic surgery
