DETAILED DESCRIPTION OF THE INVENTION

[0038] The prosthesis (1) of the invention is equipped with a front surface (6) and a back surface (3), being equipped with elements for attachment in the form of protrusions (2) that are attached to the cover material of the prosthesis (1), where each of the protrusions (2) is equipped with a hole (4) for the threading of the suture filament.

[0039] FIGS. 1 and 2 detail a model of the prosthesis (1) where the protrusions (2) are aligned on two orthogonal axes on the front surface (6) and also on the circumference (5) of the base of the spherical cap, and the protrusions (2) are equipped with holes (4) for the threading of suture filaments by the physician during surgery.

[0040] FIG. 3 details a protrusion (2) with a hole (4) that optionally may contain a supporting element (7), preferably Nylon, stainless steel or any other rigid material compatible with the human body. In one alternative modality, said support (7) may comprise a cylindrical body, with a height compatible with that of the hole (4) and two attachment rings that extend over the hole (4) of said prosthesis (1) to retain the support of the prosthesis (1), located in the lower part and in the upper part of said support (7). Through this hole (4) equipped with the support (7) of the protrusions (2) nylon threads are passed that serve to anchor the prosthesis (1) to the muscle tissue or breast tissue. The anchoring to the patient's biological tissue can be performed by sewing, a method already known to a person skilled in the art.

[0041] It is also worth highlighting that the elements for attachment in the form of protrusions (2) for the silicone prostheses, as proposed in the present invention, should form part of the body of the prosthesis, being attached to the material that covers the prosthesis to provide adequate resistance related to the rupturing of these protrusions (2) from the surfaces of the prosthesis (1).

[0042] Example 1: in a first configuration, the present invention provides a silicone prosthesis (1a) where elements for attachment are arranged in the form of protrusions (2) only positioned on the circumference (5) of the base of the prosthesis, leaving its front surface (6) smooth. Said elements for attachment (2) may be arranged only on the cardinal points of the prosthesis, as exemplified in FIG. 04, so that the prosthesis can be attached with its base in the patient's biological tissue. By way of example, in prostheses that are introduced in patients using the subglandular technique, the elements for attachment of the profile (5), can be duly attached in the muscle tissue and thus prevent the rotation of the prosthesis and provide greater stability and safety of attachment thereof.

[0043] Example 2: in a second form of execution, the present invention provides a prosthesis (1b) where elements for attachment are distributed in the form of protrusions (2) only on its front surface (6). The protrusions (2) may be arranged in different positions on their front surface (6), as exemplified in FIG. 05 so that the prosthesis (1b) is attached and does not move or rotate and, specifically, keep the breast tissue anchored thereto preventing premature ptosis and loss of shape By way of example, with prostheses introduced into patients using the submuscular technique, the prosthesis (1b) with elements for attachment in the form of protrusions (2) on the front surface (6), can be anchored to muscle tissue via nylon threads, or any other compatible material, passing through the protrusions (2).

[0044] Example 3: in a third form of execution, the present invention provides a partial prosthesis (1c) in the form of a spherical half-cap, equipped with elements for attachment in the form of protrusions (2c), exemplified in FIGS. 6 and 7. This prosthesis (1c) can be implanted through a surgery where the entire breast is not removed, a common situation in people with breast cancer, where there is a need to remove only the cancerous part. This part can be replaced by a partial or segmental prosthesis (1c), which, through the protrusions (2), is attached by a suture, a method already known to persons skilled in the art. The advantage of a partial or segmental prosthesis (1c) is that one can reconstruct the breast affected by the cancer by restoring the symmetry of the breasts without the need to operate on the contralateral breast. In reconstructions with traditional prostheses, in most cases, bilateral implants of different volumes are required.

[0045] In one modality the silicone prosthesis equipped with elements for attachment is implanted in the biological tissue.

[0046] In one modality the silicone prosthesis is used to replace biological tissue.

[0047] In one modality, the biological tissue belongs to an individual with cancer or a healthy individual.

[0048] It is important to point out that the description provided is not intended to limit the forms of execution of the inventive concept proposed here, but rather to illustrate and make comprehensible the conceptual innovations revealed in this solution. Thus, the descriptions must be interpreted in an illustrative and non-limiting manner, and there may be other equivalent or analogous forms of implementation of the inventive concept hereby revealed which are not excluded by the spectrum of protection described in the proposed solution.

[0049] This specification provides a new silicone prosthesis arrangement with handles for attachment in the muscle or breast tissue, or in other muscles that have similar anatomy, for example, in the buttocks, which possesses novelty, inventive step, descriptive sufficiency, industrial application and which, consequently, fulfills all the essential requirements for the granting of the privilege.
