TECHNICAL FIELD
[0001] The utility model relates to orthopedic surgery technical field, concretely is a kind of stretchable breast prosthesis fixed covering structure and implantable breast prosthesis. BACKGROUND
[0002] China's breast cancer incidence rate is the first in female malignant tumor, more than 70% breast cancer patients will receive mastectomy. Breast loss can bring psychological trauma to patients, seriously affect the quality of life of women, and breast reconstruction is widely recognized at home and abroad for breast cancer patients with indications. Prosthesis reconstruction becomes the most common breast reconstruction method due to its advantages such as short operation time, rapid postoperative recovery, no donor site damage, safety and reliability. In breast prosthesis reconstruction surgery, the primary condition for applying prosthesis is to have enough tissue coverage. To solve the problem of lack of prosthesis surface coverage, some biological materials or synthetic materials are increasingly used in one-step or two-step prosthesis implantation surgery, especially one-step reconstruction surgery, combined or not combined with muscle tissue to cover the prosthesis to form a better inframammary fold shape and reduce the incidence of prosthesis implantation capsular contracture, and bring better aesthetic effect and psychological comfort to patients. In addition, in breast augmentation, breast shaping and orthopedic surgery, biological materials or synthetic materials are also needed to reduce postoperative complications.
[0003] Biological tissue materials made from animal or human tissue processing are gradually used in various surgical operations such as female breast augmentation, breast reconstruction and breast shaping and orthopedic surgery in recent years. Since these tissue materials are usually planar membrane materials, during breast reconstruction, doctors need to cut and shape them on site according to the required area size, and the specifications and shapes are irregular, which often cannot match the selected breast prosthesis and the patient's surgical area well. For example, it is difficult to avoid folding and shrinking, difficult to control the shape of the breast, and difficult to achieve the upright posture of the reconstructed breast. At the same time, since such materials are very expensive, doctors rely on visual inspection to cut and shape them on site, which is prone to errors, wasting materials and increasing surgical costs.

[0029] The following refers to Figure 1 The stretchable breast prosthesis fixing and covering structure provided in the embodiment of the present application will be described in detail.
[0030] As Figure 1 shown, the breast prosthesis fixing and covering structure provided in the embodiment includes a support part 1, a folded part 2 and a hole part 3 arranged on the support part 1.

[0031] Specifically, the support part 1 is configured as a circular structure, which corresponds to and covers the convex surface of the breast prosthesis in the cooperative application with the breast prosthesis, and plays a role of overall bearing for the breast prosthesis. The radius of the circular support part 1 is usually set to 5-8 cm, and the specific size can be set according to the convex surface area of the breast prosthesis.
[0032] The folding part 2 is configured as a plurality of groups, each folding part 2 is sequentially arranged on the outer edge of the circular support part 1 in the circumferential direction, and in the cooperative application with the breast prosthesis, the folding part 2 is folded and gathered, and then the edge of the breast prosthesis is wrapped, at this time, the adjacent folding parts 2 are sutured and connected between the far ends, so that each folding part 2 is connected and covers the other side of the breast prosthesis, and then forms a wrapped fixation for the breast prosthesis.
[0033] More specifically, in the embodiment, the folding part 2 is generally configured as a triangular structure, which is formed by the outer edge of the support part 1 being segmented and gradually narrowed in the direction away from the center of the circle, and the narrowed structure of the far end of the folding part 2 makes the gathering effect of each folding part 2 better in the sutured state, and then the wrapping of the breast prosthesis is stronger.

[0036] The number of folding parts 2 is set to 8-16 groups to ensure the surrounding gathering effect of the folding parts 2, and if the number is too small, the wrapping effect on the breast prosthesis is poor, and considering the convenience of operation of medical personnel, the number should not be too large, and preferably 8 groups.
[0037] Continuing to refer to Figure 1 In the embodiment, the hole part 3 is arranged on the support part 1, which includes a plurality of hole groups, each hole group further includes a plurality of drainage holes 4 arranged in a ring array, and the plurality of hole groups are distributed in a ring sleeve type, for example, the inner ring is a first hole group, the radius of the second hole group adjacent to the first hole group is greater than that of the first hole group, and the second hole group is sleeved on the periphery of the first hole group, the radius of the third hole group adjacent to the second hole group is greater than that of the second hole group, and the third hole group is sleeved on the periphery of the second hole group, and so on, that is, the radius of the nth hole group is greater than that of the n-1th hole group, and the nth hole group is sleeved on the periphery of the n-1th hole group.
