Description

[0001] This application is a divisional application of Chinese patent application No. 2024104009371, filed on April 3, 2024, entitled "A 'Frown-shaped Implant Prosthesis'". Technical Field

[0002] This invention relates to the field of medical aesthetics, specifically to an implantable aegyo sal (eyelid scar) implant. Background Technology

[0003] In the past, to improve the shape of the lower eyelid (aegyo sal), injectable fillers or implants of dermis, fascia, or even relatively rigid threads were often used to increase its fullness. However, these fillers are absorbed and do not provide long-lasting results, requiring regular injections. Furthermore, improper injection can easily lead to problems such as increased translucency. If implanted dermis or fascia fails to achieve the desired shape and needs to be removed after three months, the dermis may have grown together with the surrounding tissue, requiring a complete surgical incision for removal – a difficult and invasive procedure. Rigid threads are undoubtedly completely unsuitable for the soft and dynamic lower eyelid area. Summary of the Invention

[0004] To address the technical problems existing in the prior art, the present invention provides a subcutaneous implant for the lower eyelid, which can restore the mountain-like structure of the lower eyelid when viewed from the side.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A type of eyelash implant, characterized in that: the implant is elongated; the cross-sectional shape of the implant is triangular; the implant is constructed to fit into a cavity above the lower eyelid, and its structure allows the implant to maintain the triangular shape with one corner facing upward even if it flips within the cavity; thereby avoiding the upper edge of the implant from pressing upward and forming artificial ingrown eyelashes.

[0007] As a preferred technical solution, the maximum width of the prosthesis cross-section does not exceed 3mm.

[0008] As a preferred technical solution, the cross-sectional shape of the prosthesis is an equilateral triangle.

[0009] As a preferred technical solution, the three sides of the equilateral triangle in the cross-section of the prosthesis are concave inward.

[0010] As a preferred technical solution, the corners of the equilateral triangle are designed to be arc-shaped.

[0011] As a preferred technical solution, the prosthesis is made of soft material.

[0012] As a preferred technical solution, the soft material is silicone.

[0013] As a preferred technical solution, the prosthesis is a triangular prism of uniform thickness.

[0014] As a preferred technical solution, the prosthesis is divided into several segments from one end to the other, ranging from thin to thick, with each segment having a uniform thickness.

[0015] As a preferred technical solution, the length of the prosthesis is configured to be cut according to the length of the user's palpebral fissure.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The eyelid implant of this invention has a special shape and is made of soft materials such as silicone. While maintaining softness, it also maintains a specific shape and height. It will not be absorbed and can ensure the continuous height of the eyelid. A thin channel is opened under the orbicularis oculi muscle of the lower eyelid through a minimally invasive incision. The implantation cavity is correct and will not shift or widen. If the muscle is thin, a smaller size implant can be selected, or the reserved position on the type II implant can be covered with fascia to increase tissue thickness and prevent it from becoming visible. The implantation only requires a small incision of about 5mm for minimally invasive surgery. If adjustment or removal is needed later, it can be removed or replaced through a small incision. Both placement and removal are minimally invasive surgeries. It will not cause large trauma or adverse effects on later operations due to fusion with tissue growth, allowing for greater flexibility in the later stages of surgery. Attached Figure Description

[0023] The technical solution of the present invention will be further described below with reference to specific embodiments:

[0024] Example 1

[0025] like Figure 3As shown, a type of under-eye bag implant involves creating a narrow channel beneath the orbicularis oculi muscle through a minimally invasive incision, and then inserting the implant into the cavity. Figure 1 As shown, the implant is prism-shaped with a cross-sectional shape of an equilateral triangle. The implant can be a single segment of a uniformly thick triangular prism. Alternatively, it can be a combination of several segments, each with a uniform thickness, arranged from thin to thick.

[0026] The implantation only requires a small incision of about 5mm, which is a minimally invasive surgery. If adjustments or removal are needed later, it can also be done through a small incision. Both placement and removal are minimally invasive surgeries, and there will be no large trauma or adverse effects on later operations due to the growth and fusion with the tissue. This allows for greater flexibility in the later stages of the surgery.

[0027] Analysis of over 1000 aegyo sal surgeries yielded optimal implant morphology data, including the implant's shape, thickness, and firmness, which has been surgically verified. Considering implant safety, stability, and the restoration of morphological realism, a triangular cross-section was ultimately chosen. Even if it flips within the cavity, it will always maintain a triangular shape with one corner pointing upwards. Other cross-sectional shapes were excluded because circular, rectangular, or other shaped implants, when placed above the tarsal plate, would cause the upper edge of the implant to press upwards, easily leading to artificially induced trichiasis.

[0028] The cross-sectional side length of the implant does not exceed 3mm, thus minimizing the implant's visibility. The design concept is not to fill the lower eyelid with a large volume, but rather to support and elevate it to a certain extent (1-3mm in height) with a smaller volume. Furthermore, it is easy to implant and remove, resulting in minimal trauma and a quick recovery.

[0029] The implant is made of linear soft materials such as silicone.

[0030] To prevent the sharp edges of the implant from damaging the muscles, the corners of the equilateral triangle in the cross-section of the implant can be designed as arcs.

[0031] When using it, select a section of suitable thickness from the prosthesis and cut the length of this section according to the length of the user's palpebral fissure.

[0032] Example 2

[0033] For users with thin muscles, to avoid implant visibility, smaller implants can be chosen; implants with a maximum width of 3mm have a lower visibility rate. Alternatively, dermis or fascia can be used to cover the pre-existing space of the implant to increase tissue thickness and prevent visibility. Specifically, such as... Figure 2 As shown, based on Example 1, the cross-section of the prosthesis is designed as a special shape with three sides of an equilateral triangle concave inward, so as to make the structure softer and reserve space for fascia coverage. Figure 4 Three sizes of cross-section for this special-shaped prosthesis are provided, and the size can be further fine-tuned according to the actual situation. For example... Figure 5 As shown, this type of prosthesis can maintain its triangular structure even after covering the fascia.

[0034] Other embodiments

[0035] Strips of silicone can also be cut from other silicone implants to serve as filler implants, but because fine-tuning and sculpting to a size of 1mm-3mm is extremely difficult for doctors, it is hard to achieve the existing specific size and shape.

[0036] This embodiment is merely a further explanation of the present invention and is not intended to limit the present invention. Those skilled in the art can make non-inventive modifications to this embodiment as needed after reading this specification, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
