Description

A kind of eyebag implant prosthesis Technical Field

[0001] The present invention relates to the field of medical cosmetology, and in particular to an under-eye bag implant prosthesis. Background Art

[0002] In the past, efforts to improve the shape of the under-eye bags often involved injectables, implants into the dermis or fascia, or even relatively rigid wires to increase their fullness. However, these injectables are absorbed and cannot be maintained for long periods of time, requiring regular injections. Improper injections can also lead to problems such as increased light transmission. If the dermis or fascia implants are poorly shaped and require removal after more than three months, the dermis will have grown together with the surrounding tissue, necessitating a complete incision and removal, which is difficult and invasive. Rigid wires are undoubtedly unsuitable for the soft and dynamic area of ​​the under-eye bags.

[0003] Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, the present invention provides an under-eye bag implant prosthesis, which can solve the problems of non-absorption and durability of fillers and can restore the mountain-like structure of the under-eye bag when viewed from the side.

[0005] To achieve the above object, the technical solutions of the present invention are as follows:

[0006] The invention discloses an eyebag implant prosthesis, which is used for being implanted below the orbicularis oculi muscle of the inferior palpebral eye. The prosthesis is prism-shaped and has a cross-sectional shape of an equilateral triangle.

[0007] As a preferred technical solution, the prosthesis is a triangular prism with uniform thickness.

[0008] As a preferred technical solution, the prosthesis is divided into several sections from thin to thick from one end to the other, and the thickness of each section is uniform.

[0009] As a preferred technical solution, the cross-sectional side length of the prosthesis does not exceed 3 mm.

[0010] As a preferred technical solution, the prosthesis adopts linear soft material.

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

[0012] As a preferred technical solution, the three sides of the equilateral triangle of the prosthesis cross section are concave inward to reserve space for fascia coverage.

[0013] As a preferred technical solution, when in use, the length of the prosthesis is cut according to the length of the user's palpebral fissure.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The eyebag implant prosthesis of the present invention has a special shape and is made of soft materials such as silicone. It maintains softness while also maintaining a specific form and height. It will not be absorbed and can ensure the continuous height of the eyebag. A thin strip channel below the orbicularis oculi inferioris muscle is opened through a minimally invasive incision. The implant cavity is correct and will not shift or widen. If the muscle itself is thin, a smaller prosthesis can be selected, or the fascia can be covered in the reserved position on the type II prosthesis to increase tissue thickness and prevent it from being visible. Implantation only requires a small incision of about 5mm for minimally invasive surgery. If adjustment or removal is needed later, only a small incision is needed to extract or replace it. Placement and removal are both minimally invasive surgeries. There will be no large trauma to later removal due to fusion with tissue growth, which will have an adverse effect on later operations, leaving more room for maneuver in the later stages of the operation.

[0021] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0022] Example 1

[0023] As shown in Figure 3, a prosthesis for under-eye bags is implanted. A minimally invasive incision is made to open a thin, strip-shaped channel beneath the orbicularis oculi muscle of the inferior palpebral eyelid, allowing the prosthesis to be implanted into the cavity. As shown in Figure 1, the prosthesis is prismatic, with a regular triangular cross-section. The prosthesis can be a triangular prism with uniform thickness. Alternatively, the prosthesis can be a composite structure consisting of several segments that are arranged from one end to the other, increasing in thickness, with each segment having uniform thickness.

[0024] Implantation only requires a minimally invasive surgery with a small incision of about 5mm. If adjustment or removal is needed later, only a small incision is needed to extract or replace it. Both placement and removal are minimally invasive surgeries. The subsequent removal will not cause severe trauma due to fusion with tissue growth, which will have an adverse effect on subsequent operations, leaving more room for maneuver in the later stages of the operation.

[0025] The morphological data of the prosthesis, including the shape, thickness, hardness, etc., were obtained by analyzing more than 1,000 eyebag surgeries and have been verified by surgery. Considering the safety and stability of the implant, as well as the restoration of the morphological authenticity, a triangular cross-section was finally selected. Even if it is flipped in the cavity, the triangle shape will always be kept with one corner facing upwards. In addition, other cross-section shapes were excluded because when a prosthesis with a circular, rectangular or other cross-section is placed above the tarsal plate, the upper edge of the prosthesis will be pressed upwards, which can easily lead to artificial trichiasis.

[0026] The cross-sectional length of the implant does not exceed 3mm, which reduces the visibility of the implant itself. The design concept is not to use a large volume to fill the bags under the eyes, but to use a smaller volume to support and elevate the bags under the eyes to a certain extent (1-3mm height). It is easy to implant and remove, with minimal trauma and fast recovery.

[0027] The prosthesis is made of linear soft materials such as silicone.

[0028] In order to prevent the sharp corners of the prosthesis from causing damage to the muscles, the corners of the equilateral triangle of the prosthesis cross section can be designed to be curved.

[0029] When using, select a section of appropriate thickness from the prosthesis and cut the length of this section according to the length of the user's palpebral fissure.

[0030] Example 2

[0031] For users with thin muscles, in order to avoid the prosthesis being visible, a smaller prosthesis can be selected. The prosthesis with a maximum width of no more than 3mm has a lower visibility rate. Alternatively, the dermis or fascia can be covered in the reserved position of the prosthesis to increase the tissue thickness and prevent it from being visible. Specifically, as shown in Figure 2, based on Example 1, the cross-section of the prosthesis is designed to be a special shape with three sides of an equilateral triangle concave inward, so as to make the structure softer and reserve a position for fascia coverage. Figure 4 provides three sizes of the cross-section of the prosthesis with this special shape, and the size can also be fine-tuned according to actual conditions. As shown in Figure 5, the prosthesis of this design can still maintain a triangular structure after being covered with fascia.

[0032] Other embodiments

[0033] Silicone strips can also be cut from other silicone prostheses to serve as filling prostheses, but because fine-tuning and carving of 1mm-3mm in size is extremely difficult for doctors, it is difficult to achieve the current specific size and shape.

[0034] This embodiment is only a further explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
