Description

Breast prosthesis with changeable volume

Technical Field

The utility model relates to the field of medical instruments, in particular to a breast prosthesis with a changeable volume.

Background

The breast is a symmetrical organ, and the aesthetic of the breast is most importantly bilaterally symmetrical. Mammary prostheses have been used clinically for decades, from liquid silicone at the beginning to saline injection to semi-gel silicone, which is now commonly used, and also from round to drop-shaped in shape, but have certain disadvantages in clinical use. For example, the prosthesis selected is often not suitable due to many uncertainties such as posture, tissue edema, and post-operative recovery during surgery. In addition, the prosthesis in the market is set to be one model per 50ml, so that the prosthesis with the same size as the contralateral breast is difficult to select, and the bilateral breast is asymmetric.

The existing silica gel prosthesis has high density and high local skin pressure, and is easy to cause skin flap necrosis. Part of patients have a load feeling and are easy to feel uncomfortable; and the existing silica gel prosthesis is easy to crack or leak, thereby causing serious consequences.

Most of silica gel prostheses in the current market are integrally formed, most of the models are fixed, and when the silica gel prostheses are selected for use, an embarrassing situation that the silica gel prostheses with proper sizes cannot be found is easily generated, so that the aesthetic property of postoperative recovery of patients is influenced, and therefore, a breast prosthesis with the size capable of being changed at will is needed.
