In the related art, for mild and moderate ptosis, a levator palpebrae superioris shortening operation is generally adopted. This approach, as shown in figure 3, achieves increased strength of open eye by shortening the levator palpebrae superioris. The operation requires cutting the double eyelid, peeling from the skin approach to the surface of the upper eyelid elevator, then separating, cutting off the upper eyelid elevator, and shortening and suturing again to fix the upper eyelid elevator. Finally, the skin is sutured according to the suturing mode of cutting the double eyelid. The operation type has the advantages of large injury in operation, obvious postoperative swelling, long recovery time and scar remaining on skin. Second, ptosis correction is likely to recur, and once it recurs, the procedure needs to be repeated again, increasing the difficulty of the procedure and the skin scarring may be more pronounced.

In order to solve the technical problem, the present embodiment provides an internal route superior eyelid elevator separator 1, and the traditional percutaneous incision approach can be changed by using the internal route superior eyelid elevator separator 1 to perform the superior eyelid elevator shortening operation. Specifically, as shown in fig. 1, the present embodiment provides an internal circuit superior eyelid elevator separator 1, where the internal circuit superior eyelid elevator separator 1 includes: an arc segment 102, a needle tip segment 103 and a connecting segment 101;

the needle point section 103 and the connecting section 101 are respectively positioned at the first end and the second end of the arc section 102, and an injection port 1021 is formed in the outer circle side of the arc section 102;

the interior of the arc-shaped section 102 and the interior of the connecting section 101 are arranged in a hollow manner and are communicated with each other to form an injection cavity 1011; the injection cavity 1011 communicates with the injection port 1021;

the end of the connecting section 101 away from the arc-shaped section 102 is provided with an injection port communicating with the injection cavity 1011.

In this embodiment, the internal superior eyelid levator separator 1 mainly includes three parts, which are an arc-shaped section 102, a needle tip section 103 and a connecting section 101, wherein the needle tip section 103 and the connecting section 101 are respectively located at two ends of the arc-shaped section 102. In use, as shown in figure 2, the tarsal plates need to be inverted to allow access to the inner conjunctiva 3.

As shown in fig. 1 and 2, the tip section 103 ends in a sharp tip structure, which is used to pierce the subcutaneous tissue and thus is located at the foremost end of the eyelid elevator separator 1 on the medial path. Since the separator is also pulled during the procedure to provide a greater separation between the conjunctiva 3 and the levator palpebrae superioris muscle 4, the separator also has an arcuate segment 102 that allows the separator to hook over the conjunctiva 3. Specifically, the tip segment 103 can be inserted into the conjunctiva 3 from one location on the conjunctiva 3 and then exit from another location on the conjunctiva 3 such that the arc segment 102 is located inside the conjunctiva 3, i.e., between the conjunctiva 3 and the upper eyelid elevator 4.

In order to separate the conjunctiva 3 and the levator palpebrae superioris 4, the physiological saline 2 is injected between the conjunctiva 3 and the levator palpebrae superioris 4. Therefore, in the present embodiment, an injection port 1021 is formed on the outer circumference side of the arc-shaped section 102, the injection port 1021 faces the eyelid elevator 4, and the inside of the arc-shaped section 102 and the inside of the connecting section 101 are arranged and communicated in a hollow manner to form an injection cavity 1011; the injection cavity 1011 communicates with the injection port 1021.

In order to facilitate the injection of the saline 2 into the injection cavity 1011, an injection port communicating with the injection cavity 1011 may be formed at an end of the connection section 101 away from the arc-shaped section 102. Therefore, when the saline 2 needs to be injected, an external injection device may be docked on the injection port, and then the saline 2 is injected into the injection cavity 1011, and the saline 2 flows along the injection cavity 1011 and flows out through the injection port 1021. Since the injection port 1021 is located at the arc-shaped section 102 and is disposed toward the upper eyelid elevator 4, the saline 2 can flow between the upper eyelid elevator 4 and the conjunctiva 3 through the injection port 1021, thereby separating the conjunctiva 3 and the upper eyelid elevator 4. At this time, the separator may be pulled outward so that the space between the conjunctiva 3 and the levator palpebrae superioris 4 is further enlarged, and then a nylon thread is used to suture to the meibomian plate through the levator palpebrae superioris 4, thereby achieving the purpose of shortening the levator palpebrae superioris 4.

Compared with the prior art in which the double eyelids are cut, the double eyelids are directly conveyed to the surface of the upper eyelid elevator 4 from the skin approach, then the upper eyelid elevator 4 is separated and cut off, and the upper eyelid elevator 4 is shortened and fixed again (as shown in fig. 3), the inner route upper eyelid elevator separator 1 provided by the embodiment can be used for the approach from the inner conjunctiva 3 without damaging the skin on the outer surface, and the double eyelids are not cut during use, the skin incision scar is formed, the tissue injury is reduced, and the postoperative recovery period is greatly shortened (as shown in fig. 2). Furthermore, after ptosis correction, the long term may recur and require re-operation. The internal path eyelid elevator separator 1 in the embodiment can be used repeatedly, and the complication of the traditional operation type repeated incision is avoided.

In order to improve the structural compactness and the integrity of the separator, the arc-shaped section 102, the needle point section 103 and the connecting section 101 are integrally formed, and the main structure of the separator can be a 27G puncture needle.

To improve the accuracy of the injection direction of the saline 2, an injection port 1021 is formed at the top end of the arc-shaped section 102.

For facilitating puncture, the connecting section 101 is cylindrical, and the axis of the connecting section 101 is perpendicular to the end surface of the second end of the arc-shaped section 102, so that the internal levator palpebrae muscle separator 1 is integrally J-shaped, and the conjunctiva 3 can be pulled by the separator while facilitating puncture.

As shown in FIG. 1, the vertical distance between the end of the tip segment 103 away from the arc segment 102 and the connecting segment 101 is 3mm-5 mm. Preferably, the vertical distance between the end of the needle tip section 103 away from the arc section 102 and the connecting section 101 is 4 mm.

As shown in fig. 1, the diameter of the injection port 1021 is 1mm-2mm, and preferably, the diameter of the injection port 1021 is 1.5 mm.

As shown in fig. 1, in order to facilitate the butt joint between the injector and the injection port, an injection tube 104 is fixedly disposed at one end of the connecting section 101 away from the arc-shaped section 102, a connecting groove 1041 for connecting with the injector is disposed in the injection tube 104, and the connecting groove 1041 is communicated with the injection port. When the separator is used, the injection end of the injector can be inserted into the connecting groove 1041, the connecting groove 1041 provides a positioning reference for the injector, so that the injection end of the injector can be accurately butted with the injection port, the physiological saline 2 is injected, and the use convenience of the separator is improved.

To further enhance the positioning of the syringe, the inner contour of the connecting slot 1041 matches the outer contour of the syringe injection end; to avoid leakage of saline 2 from the end of the syringe 104, the connection of the syringe 104 to the connecting section 101 is sealingly arranged.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
