Description

Sutures for long-lasting skin retention

This invention relates to a medical suture, especially a suture that can retain skin for a long time.

A suture is a medical material used to close wounds in the skin or other tissue. There are a variety of materials available for suturing. Doctors use sutures and suture techniques to repair wounds according to different wounds or operations.

Generally speaking, sutures can be divided into absorbable and non-absorbable sutures according to their materials. Absorbable sutures are mainly used in tissues or subcutaneously. They do not need to be removed after the wound is sutured. Non-absorbable sutures are mainly used for suturing the skin. They need to be removed after the wound heals. However, in some cases, in order to maintain the tightness of the sutured tissue, it is not desirable for the sutures to be absorbed. Sometimes non-absorbable sutures are also used in body tissues. of sutures.

For example, the "suture for plastic surgery" disclosed in the Republic of China Patent No. M580945 includes a thread body and multiple sharp thorns. The wire body has a plurality of first slots, a plurality of second slots and a third slot. The first slots, the second slots and the third slots respectively extend obliquely from the peripheral surface of the wire body toward the axis of the wire body. The sharp thorns protrude obliquely from the outer peripheral surface of the wire body and are integrally connected to the root of the first slot, the root of the second slot and the root of the third slot respectively. These sharp thorns are cut out from the outer peripheral surface of the alignment body The first cutting grooves, the second cutting grooves and the third cutting grooves are formed at the same time. Each cutting groove will form a sharp thorn at the same time, and these sharp thorns will protrude obliquely. The outer surface of the line body.

However, since the first grooves, the second grooves and the third grooves of the conventional sutures respectively extend obliquely from the peripheral surface of the thread body toward the axis center of the thread body, in an oblique shape, it is difficult to fix the sutures during binding. It is easier to fall off when threading.

Therefore, how to improve the above-mentioned deficiencies is the technical difficulty that the creator of this case wants to solve.

In view of the conventional usage, this creation aims to solve and improve the existing problems and deficiencies in the conventional usage.

In order to achieve the above purpose, this invention provides a suture that can permanently retain skin, which includes: a line body provided with a plurality of planar grooves; and a plurality of thorns respectively provided on the line body, and the The spines are connected to the flat groove.

Wherein, the plurality of spines are arranged on the wire body in a linear arrangement.

Wherein, the plurality of spines are arranged on the thread body in a spiral arrangement.

Wherein, the gaps between the plurality of thorns are equal intervals.

Wherein, the gaps between the plurality of thorns are unequal intervals.

In this invention, since the wire body is provided with a plurality of flat grooves instead of the inclined grooves in the conventional technology, the binding wire is stronger and less likely to fall off.

In order to allow your examiner to easily and concisely understand the other features and advantages of this creation and the effects achieved by it, this creation is accompanied by the attached drawings and the detailed description is as follows:

Please refer to Figure 1. This invention provides a suture that can permanently retain skin, which includes: a thread 1 and a plurality of spines 2.

The wire body 1 is provided with a plurality of planar grooves 11 . The wire body 1 may have multiple layers, such as an inner wire core, an intermediate layer covering the wire core, and an outer layer covering the middle layer. And the surface of the outer layer can be coated with materials that promote skin repair, such as collagen. The thread body 1 can be classified into absorbable or non-absorbable according to the material. Absorbable materials include plain catgut, chromic gut, polyglycolic acid (Dexon), polyglycolic acid lactic acid (Vicryl), Polycaprolactone (PCL), polypropylene carbonate (PPC), polytrimethylcarbonate (Polytrimethylene carbonate), polydioxanone (PDO), polyglycoside ester (PGA), copolymer (PLGA), lactide (LA) or polydioxanone (PDS), or non-absorbable materials such as silk, cotton, nylon ), polyester, polyethylene, polypropylene, polytetrafluoroethylene, stainless steel or polybutyl, etc.). In this embodiment, the material of the wire body 1 is polydioxanone (PDO) or polycaprolactone (PCL). PDO wire, like other wires, also has three types: smooth wire, spiral wire and zigzag wire, and zigzag wire It is divided into many types such as one-way sawtooth, two-way sawtooth, and cross sawtooth. The main differences between PDO wire and PCL wire are life span and tensile strength. PCL wire is longer lasting than PDO wire and has higher tensile strength.

The plurality of thorns 2 are respectively provided on the wire body 1 , and the thorns 2 are connected to the planar groove 11 .

The plurality of spines 2 can be arranged on the wire body 1 in a linear arrangement (shown in Figure 1). The plurality of spines 2 can also be arranged on the wire body 1 in a spiral arrangement (shown in Figure 2). The gaps between the plurality of spines 2 can be equally spaced (shown in Figure 3). The gaps between the plurality of spines 2 can also be unequal intervals (shown in Figure 4).

As shown in Figure 1, in terms of the processing method, a cutter (not shown in the figure) can be used to cut a plurality of plane grooves 11 on the wire body 1 (that is, the bottom of the groove is flattened). Each time a plane groove 11 is cut, At the same time, a thorn-shaped object 2 is formed, and the thorn-shaped object 2 is connected to the planar groove 11 in a one-to-one manner.

Compared with the prior art, this creation has a plurality of flat grooves 11 on the wire body 1 instead of the inclined grooves in the prior art. Therefore, in comparison, the binding wire is stronger and less likely to fall off. , in use, it will not be unable to stay on the skin for a long time due to falling off.

The above discussion is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention; therefore, any equivalent changes in shape, structure or combination that do not deviate from the spirit and scope of the present invention should be made. Covered within the scope of the patent application for this creation.
