AI Technical Summary
Existing techniques often lead to incision contracture due to adhesion of surrounding scars after facial scar excision, and the thin sutures can cause noticeable ligature marks after suture removal.
A knotless self-locking suture device is used, which includes a suture body, a fishbone, and an insertion blocking mechanism. It uses a corner needle for insertion, the fishbone prevents the suture body from moving backward, and the insertion blocking mechanism prevents the suture body from passing through, thus avoiding knots and simplifying the suturing process.
It effectively avoids the formation of suture marks, shortens operation time, improves suturing efficiency, prolongs wound healing time, and reduces postoperative scar contracture.

TECHNICAL FIELD
[0001] The utility model relates to a suture device, in particular to a knotless self-locking suture device for facial scar excision postoperative. BACKGROUND
[0002] Current surgical treatment of facial acne postoperative atrophic scar, the current surgical method is to carry out ice cone and carriage type scar trepanning, trepanning lifting, surgical knife lifting.
[0003] These types of scars are very small, the diameter is 0.5-5.0mm, but in the deep and surrounding of this scar, there is potential scar, so after operation excision, suture, lifting postoperative suture, the common problem encountered is: 1. because of the adhesion of surrounding scar causes the contracture of incision; 2. the large incision tension + the very thin suture together causes the obvious scar after suture removal on the skin surface. Figures 4-5 And lifting operation suture Figures 6-7 . INVENTION CONTENTS

[0005] In order to achieve the above purpose, the utility model provides the following technical scheme: the utility model discloses a line body for use and the fishbone thorn arranged on the line body, and further includes an angle needle and a blocking mechanism, one end of the line body is connected with the angle needle, and the other end of the line body is provided with the blocking mechanism for blocking.
[0006] Preferably, the thickness of the line body is between 2-0 and 7-0.
[0007] Preferably, the blocking mechanism is composed of a spherical body with a diameter larger than that of the line body.
[0008] Preferably, the blocking mechanism is composed of a disc with a diameter larger than that of the line body.
[0009] Preferably, the line body with a thickness between 2-0 and 5-0 is made of absorbable material.
[0010] Preferably, the line body with a thickness between 6-0 and 7-0 is made of non-absorbable material.
[0011] Beneficial effects: when the utility model is used, when performing scar operation incision and suture, the angle needle is used to insert the line body at the incision position, the fishbone thorn prevents the line body from moving reversely along the puncture hole, the blocking mechanism blocks the end of the puncture hole, and the line body cannot pass through the puncture hole, so that the line body can be used for suturing the suture part, and knotting of the line body is not needed, no marks are caused, treatment effect is ensured, and the suture effect diagram is as follows Figure 2 Operation, such as Figure 3 Lifting operation, when the line is removed, the line body can be pulled out by only cutting off the blocking mechanism, and the operation is simple and convenient. The utility model has novel structure, ingenious design, and is convenient for suturing scar operation and lifting operation, greatly shortens the operation time, prevents marks after operation, and simultaneously can make the wound heal more fully by appropriately prolonging the line removal time, and reduce the degree of postoperative scar contracture.

[0021] The specific embodiments of the utility model are further explained in detail below. Figures 1-3 The specific embodiments of the utility model are further explained in detail below.
[0022] Embodiment one, byFigures 1-3 The present invention provides a knotless self-locking suture device for facial scar excision surgery, including a suture body 1 for use and a fishbone spur 2 provided on the suture body 1, as well as a corner needle 3 and an insertion blocking mechanism 4. One end of the suture body 1 is connected to the corner needle 3, and the other end of the suture body 1 is provided with an insertion blocking mechanism 4 for preventing insertion.
[0023] The thickness of thread 1 ranges from 2-0 to 7-0, making it easy to use.
[0024] The obstruction mechanism 4 is composed of a sphere with a diameter larger than that of the thread 1, which facilitates the obstruction of the thread 1 during sewing.
[0025] The obstruction mechanism 4 is composed of a disc with a diameter larger than that of the thread 1, which facilitates the obstruction of the thread 1 during sewing.
[0026] The thread 1 has a thickness between 2-0 and 5-0 and is made of absorbable material to facilitate absorption.
[0027] The thread 1 has a thickness between 6-0 and 7-0 and is made of non-absorbent material for easy use.
[0028] Working Principle: When using this invention for scar excision and suturing, the corner needle 3 is inserted into the area requiring suturing, and the suture 1 is inserted at the surgical incision site. The fishbone-like protrusions 2 prevent the suture 1 from moving backward along the puncture hole, and the blocking mechanism 4 blocks the end of the puncture hole, preventing the suture 1 from passing through. In this way, the suture 1 can be used to suture the area without the need for knotting, thus avoiding ligature marks and ensuring the treatment effect. The suturing effect is shown in the figure. Figure 2 Resection surgery, such as Figure 3 During the lifting surgery, when removing the sutures, simply cut off the blocking mechanism 4 to pull out the suture 1; the operation is simple and convenient.
[0029] Beneficial effects: This utility model has a novel structure and ingenious design, which facilitates suturing in scar surgery and lifting procedures, greatly shortens the operation time, eliminates postoperative ligature marks, and allows for more complete wound healing and reduces the degree of postoperative scar contracture by appropriately extending the suture removal time.
