Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a tension-reducing suture thread used for scar surgery. Background Art

[0002] The purpose of plastic surgery to treat scars is to reduce the size of obvious scar tissue and leave as few obvious marks as possible. During surgery, tension-reducing sutures are used to reduce the tension on the incision, which is beneficial for skin healing. Sutures are needed to suture the incision.

[0003] In the prior art, a rubber tube is sometimes placed on the outside of the suture to contact the skin near the incision, thereby reducing the pressure of the suture on the skin tissue. However, the traditional rubber tube has a relatively simple structure, and the knotted and trimmed suture thread is directly exposed at one end of the rubber tube, which can easily compress the nearby skin tissue and cause discomfort to the patient.

[0004] Therefore, we propose a tension-reducing suture for scar surgery. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the rubber tube structure is relatively simple, the thread ends of the suture thread after knotting and trimming are directly exposed at one end of the rubber tube, which easily compresses the nearby skin tissue and causes discomfort to the patient, and to propose a tension-reducing suture thread for scar surgery.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A tension-reducing suture for scar surgery, comprising:

[0008] A suture, wherein the two ends of the suture are close to each other and tied with a knot, and the trimmed thread ends are left at the knot;

[0009] It also includes a rubber tube, which includes a tube body. The bottom of the tube body is provided with a bottom surface, which is a plane. The inner side of the tube body is provided with a circular inner cavity, the suture thread passes through the inner cavity, and the thread head is located in the inner cavity. The top outer wall of the tube body is provided with a circular give way groove, and the top outer wall of the tube body is provided with a strip-shaped notch. The give way groove and the notch are connected, and the give way groove and the notch are both connected to the inner cavity. Guide surfaces are provided on both sides of the top of the notch.

[0010] In a possible design, side surfaces are formed on both sides of the bottom surface, and the side surfaces are arc-shaped.

[0011] In a possible design, a plurality of evenly distributed anti-slip bumps are integrally formed on the bottom of the bottom surface.

[0012] In a possible design, the length of the notch is 1-1.2 cm.

[0013] In a possible design, the length of the rubber tube is 2-2.5 cm.

[0014] In a possible design, the guide surface is an inclined surface.

[0015] In a possible design, the guide surface is a curved surface.

[0016] In this application, when in use, the doctor uses tools such as tweezers and clamps to suture the incision. After the suturing is completed, the rubber tube is trimmed to the appropriate length using a scissors, and then the rubber tube is strung onto the suture thread, and then the suture thread is knotted. After the knotting is completed, the knot is automatically gathered into the inner cavity, and then the suture thread is trimmed with scissors, and the thread end is stuffed into the inner cavity from the gap using scissors to prevent the thread end from being exposed to the outside world.

[0017] Beneficial effects:

[0018] In the utility model, the tension-reducing suture used for scar surgery is provided with multiple structures such as a rubber tube, a recess and a notch. When the suture is knotted, the knot and the thread end of the suture can be placed in the inner cavity, thereby preventing the thread end from being exposed and compressing the skin tissue, thereby avoiding discomfort to the patient.

[0019] In the utility model, the tension-reducing suture used for scar surgery can prevent the rubber tube from sliding randomly by providing the bottom surface and the anti-slip bumps, making it convenient for doctors to tie knots and cut the suture.

[0020] In the utility model, the knot and thread end of the suture thread can be placed in the inner cavity to avoid the thread end being exposed and pressing the skin tissue, thereby avoiding discomfort to the patient. It can also prevent the rubber tube from sliding randomly, making it convenient for the doctor to tie the knot and cut the suture thread. BRIEF DESCRIPTION OF THE DRAWINGS
