Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic instruments, in particular to a double-tipped suture with thread, a disposable ophthalmic micro suture needle. Background Art

[0002] For traditional micro suture needles (one end is pointed and the other end is with thread), if the thread needs to be introduced into the eyeball, two channels are required. The whole suture needle must enter the eyeball through one channel and exit through another channel, which is complex, time-consuming, and causes additional puncture damage.

[0003] Existing ophthalmic micro suture needles have a pointed end and a thread at the end. When suturing and fixing an intraocular lens, there are two methods to introduce the suture into the eyeball:

[0004] First, when suturing, the whole suture needle needs to be inserted into the eyeball, and at the same time, the suture needle needs to exit the eyeball from another part; two channels are required on the eyeball and the operation is complex and time-consuming;

[0005] Second, retrograde insertion: First, a 23-gauge needle is used for puncture, and then a traditional suture needle with thread is retrograde inserted into the eyeball to send the suture into the eyeball; prior puncture operation is required. On the one hand, the puncture hole should be slightly larger than the diameter of the suture needle, and on the other hand, there is a possibility of damaging the choroid and retina during retrograde insertion.

[0006] The patent document with the publication number (CN215192882U) discloses a non-damaging absorbable suture with a needle for ophthalmic buried suture double eyelid plasty, including a first suture needle. The model of the first suture needle is a 3 / 8 arc angle needle, round needle or single needle with a size of 4×12. The end of the first suture needle is provided with a straight needle body end. The whole of the first suture needle is in a fishhook shape. The straight needle body end is fixedly connected to the first suture needle, and the whole surface of the straight needle body end is round. The connection strength between the suture and the needle is high, and the needle tail is round, avoiding scratching of the buried line point at the junction of the needle and the thread, achieving truly zero-damage suture, realizing the double-hook connection usage of the suture, breaking the traditional matching method of the suture with a needle, making a new non-damaging suture with a needle with a large suture needle and a thin suture for a single surgical procedure, avoiding the operation of threading a micro suture during the operation with a conventional suture needle by clinicians, reducing the operation time of the double eyelid plasty by the buried suture method, and making the operation process smoother;

[0007] Therefore, it is necessary to design a double-tipped suture with thread, a disposable ophthalmic micro suture needle to provide another technical solution for the above technical problems. Summary of the Utility Model

[0008] Based on this, it is necessary to provide a double-tipped suture with thread, a disposable ophthalmic micro suture needle for solving the technical problems mentioned in the above background art.

[0009] To solve the above technical problems, the utility model adopts the following technical solutions:

[0019] It can be seen without doubt that through the above technical solutions of the present application, the technical problems to be solved by the present application can surely be solved.

[0020] Meanwhile, through the above technical solutions, the present utility model has at least the following beneficial effects:

[0021] The disposable ophthalmic microsuture needle with double tips and a thread provided by the utility model is configured such that through the cooperation of a thread hole, an arc-shaped groove, a thread tail fixing groove, and a transition groove, the suture is firmly riveted on the straight needle body and is not likely to fall off. The suture moves back and forth along with the straight needle body and swings in the opposite direction by virtue of the ventral arc-shaped groove, and when swinging, it is not bent at a right angle and is not likely to break. More importantly, during the operation, only the second tip needs to enter, and the first tip can be outside the eyeball to introduce the suture, without the need for the entire straight needle body to enter. At the same time, since the first tip is outside the eyeball after the suture is introduced, the straight needle body can be withdrawn from the eyeball along the original path. Such an operation not only reduces tissue damage, but also reduces the surgical steps, lowers the difficulty, is convenient for learning and mastering, and thus is convenient, fast, minimally invasive, and highly efficient to use, with a low learning curve difficulty for the user.

It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0030] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments may be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] Referring to Figures 1 - 5 , a double-pointed suture with thread for single-use ophthalmic microsurgery, comprising a straight needle body 1 and a suture 7. First needle tips 2 and second needle tips 8 are respectively fixed at both ends of the straight needle body 1. A thread hole 3 is formed inside one end of the straight needle body 1 close to the second needle tip 8 for fixing the fixed end of the suture 7. The distance between the thread hole 3 and the second needle tip 8 is 3 mm, the diameter of the thread hole 3 is 0.03 mm, and the axis of the thread hole 3 is perpendicular to the axis of the straight needle body 1;

[0034] An arc-shaped groove 4 is formed inside the straight needle body 1 and at one end of the thread hole 3, and the arc-shaped groove 4 is located at the corresponding position on the ventral side of the suture 7 emerging from the thread hole 3, facilitating the arc-shaped swing in the opposite direction rather than right-angle bending of the suture 7 when the second needle tip 8 moves back and forth during the suture process, so that it is not easily broken;

[0035] A thread tail fixing groove 5 is formed inside the straight needle body 1 and in the direction close to the first needle tip 2 at the other end of the thread hole 3. The distance between the thread tail fixing groove 5 and the second needle tip 8 is 5 mm. A transition groove 6 is formed inside the straight needle body 1 between the thread hole 3 and the thread tail fixing groove 5; the suture 7 passes through the thread hole 3, is riveted to the thread tail fixing groove 5 through the arc-shaped groove 4, so as to prevent the suture 7 from slipping out of the straight needle body 1 during suture.

[0036] Preferably, the shape of the straight needle body 1 is a straight line shape, the length of the straight needle body 1 is 16 mm, and the diameter of the straight needle body 1 is 0.14 mm.

[0037] In this embodiment, the diameter ratio of the thread hole 3 to the straight needle body 1 is 0.03 / 0.14.

[0038] In this embodiment, the models of the suture 7 are various, such as 5-0, 6-0, 7-0, 8-0, 9-0, 10-0, and the thread length is 30 cm.

[0039] In this embodiment, Figure 4 and Figure 5 , in both cases, the left side in the figure is the end with the first needle tip 2, and the right side in the figure is the end with the second needle tip 8.

[0040] The usage process of a disposable ophthalmic microsuture needle with double tips and a thread is as follows: When in use, if the second tip 8 is selected, the tip of the second tip 8 can be inserted into the eyeball for more than 3 mm to introduce the suture 7 into the eyeball, and then normal operations can be carried out; if the first tip 2 is selected, it is no different from an ordinary suture needle, and normal operations can be carried out. When using the second tip 8, only the second tip 8 needs to be inserted into the eyeball, and the first tip 2 is outside the eyeball to introduce the suture 7. It is not necessary for the entire straight needle body 1 to enter the eyeball. At the same time, since the first tip 2 is outside the eyeball after the thread is introduced, the straight needle body 1 can be withdrawn from the eyeball along the original path (avoiding the problem that when a traditional suture needle needs to introduce the thread, the entire straight needle body 1 needs to enter, and the suture needle needs to penetrate through another channel, damaging more tissues and not being able to withdraw along the original path). Such an operation not only reduces tissue damage, but also reduces the surgical steps and difficulty, and is convenient for learning and mastering.
