Description

TECHNICAL FIELD

[0001] The utility model relates to medical cosmetology surgical instrument technical field, especially in a kind of novel cosmetic zigzag line. BACKGROUND

[0002] With the growth of age, due to the degradation between cell tissues, the skin tissue of human face begins to age and sag. With the development of medical technology, more and more technical means are applied to solve the problem of skin sagging, such as face and so on. Thread embedding surgery is one of them. The principle of thread embedding surgery is to implant thread body into subcutaneous tissue of skin. Due to the physical stimulation of thread body to skin and subcutaneous tissue, the body triggers the self-repair mechanism. In order to repair the damaged tissue, the body will secrete more collagen to increase the elasticity and tightness of the skin, and improve the problem of skin relaxation, wrinkles and so on. The surface of the traditional thread body is smooth, and it cannot effectively drag the surrounding tissue when penetrating into the skin tissue, cannot support the skin, and cannot play the role of lifting soft tissue. The stimulation to the surrounding tissue is small, and it cannot effectively stimulate the tissue to produce connective tissue, so the effect of improving the sagging of facial skin is not good.

[0003] In view of this problem, the industry has developed a cosmetic zigzag line with zigzag shape on both sides. As indicated in the disclosure text of the Chinese utility model patent with authorization announcement No. CN2640420Y, the cosmetic plastic zigzag line is made into a zigzag shape with opposite teeth on both sides of the middle part of the polypropylene circular line, the tooth root is wide and thick, and the tooth end is sharp. The cosmetic zigzag line can make the soft tissue of the sagging face support and lift unified and form a wound tissue structure, and many fiber shells are covered on the edge part of the zigzag line, so that the effect of tightening and lifting the sagging skin is good. However, in actual use, the applicant finds that the cosmetic zigzag line can only operate in one area at a time, and when it needs to cross the thin layer of tissue area, the zigzag line cannot be operated at one time, but needs to be operated twice. This increases the workload and operation difficulty of thread embedding surgery, and also increases the patient's wound, which is not conducive to the popularization and use of the technology.

Obviously, the described embodiments only constitute some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0027] In addition, the technical solutions of various embodiments in the embodiments of the present application can be combined with each other, but must be based on the realization of ordinary technical personnel in the art, and when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0028] Please refer to Figures 1 to 3 The embodiment of the present application provides a novel beauty sawtooth line (referred to as sawtooth line hereinafter), which comprises a line body 01, the line body 01 comprises at least two groups of sawtooth segments 02 and three smooth segments 05, the sawtooth segments 02 and the smooth segments 05 are arranged in an interlaced and spaced manner, the sawtooth segment 02 comprises a forward tooth segment 021, a smooth transition segment 022 and a reverse tooth segment 023; the forward tooth segment 021 and the reverse tooth segment 023 are mirror image symmetrical. In actual use, the model of the line body can be selected or trimmed according to the needs of the operation site, for example, for small-area skin lifting surgery, a part with one group of sawtooth segments is cut off and embedded in the operation site, when the sawtooth segment reaches the preset position, the sawtooth of the reverse tooth segment is inserted into the fascia layer by slightly extruding the surface skin to play a role in stretching the anchor point fixation. Then, the forward sawtooth segment is slightly extruded and the line body is pulled at the same time, and after the line body is relaxed, the forward sawtooth is inserted into the fascia layer to form a lifting anchor point. After the stretching anchor point and the lifting anchor point are fixed, the excess smooth segment line body can be removed, and after the subsequent work such as cleaning the operation site is completed, the surgery is completed. At the same time, when the sawtooth line of the embodiment of the present application is applied to cross-area (thick layer skin to thin layer skin to thick layer skin) skin lifting surgery, the operation can be completed at one time, that is, the buried line channel is once punched through to two thick layer skin areas, the sawtooth line with two groups of sawtooth segments is pushed into the buried line channel, and when the distal end sawtooth segment reaches the distal end thick layer skin, the fixing of the stretching anchor point and the lifting anchor point is completed respectively according to the small-area skin lifting surgery; at this time, the middle smooth segment of the sawtooth line passes through the thin layer skin, avoiding excessive stimulation of the sawtooth to the skin in this area, and the proximal end sawtooth segment reaches the proximal end thick layer skin, and the fixing of the stretching anchor point and the lifting anchor point is completed respectively according to the small-area skin lifting surgery, that is, the cross-area skin lifting surgery is preliminarily completed.

[0029] The sawtooth line of the embodiment of the present application can not only be used for small-area skin lifting surgery, but also can be used for cross-area (thick layer skin to thin layer skin to thick layer skin) skin lifting surgery, which can solve the technical problem that the sawtooth line of the prior art cannot be operated at one time when crossing the thin layer tissue area, and needs to be operated twice. Therefore, not only can the workload and operation difficulty of the buried line surgery be reduced, but also the patient's wound can be reduced, which is more conducive to the popularization and use of the present technology.

[0030] It is worth mentioning that the line body including two groups of sawtooth segments and three smooth segments is disclosed in the figure, and in actual application, the line body of the sawtooth segments and the smooth segments can be staggered and continuous, and the line body can be cut and segmented according to the needs.

[0031] Specifically, in an embodiment, the line body of the forward tooth segment 021 is provided with a first tooth protrusion 024 protruding outward, the first tooth protrusion 024 is a conical structure, and the first tooth protrusion 024 forms an angle of 15-45° with the axis of the line body 01; the line body of the reverse tooth segment 023 is provided with a second tooth protrusion 025 protruding outward, the second tooth protrusion 025 is a conical structure, and the second tooth protrusion 025 forms an angle of 135-165° with the axis of the line body. The first tooth protrusion and the second tooth protrusion of the conical structure which are mirror-symmetrically arranged can better embed into the fascia layer of the skin and achieve effective lifting and fixation.

[0032] Preferably, in an embodiment, the first tooth protrusion 024 forms an angle A of 30° with the axis of the line body 01, and the second tooth protrusion 025 forms an angle A' of 150° with the axis of the line body 01. The conical structure forming an angle of 30° with the axis of the line body not only facilitates the sawtooth line to be pushed into the buried line channel, but also utilizes the anchor point for fixation, thereby effectively and continuously stimulating the fascia and other skin tissues.

[0033] In an embodiment, the forward tooth segment 021 includes a tooth protrusion surface 026 composed of a plurality of groups of first tooth protrusions 024 and a smooth surface 027; the coverage range of the tooth protrusion surface 026 is 180° in the circumferential direction of the axis; the reverse tooth segment 023 includes a tooth protrusion surface 026' composed of a plurality of groups of second tooth protrusions 025 and a smooth surface 027'; the coverage range of the tooth protrusion surface 026' is 180° in the circumferential direction of the axis. This structure can be applied to the area where the fascia layer is thin on one side, that is, the tooth protrusion surface is anchored with the side where the fascia layer is thick, and the smooth surface is attached to the side where the fascia layer is thin, so that the skin tissue can be stimulated while avoiding excessive stimulation of the area where the fascia layer is thin.

[0034] In another embodiment, the coverage range of the tooth protrusion surface 206 of the forward tooth segment 021 and the reverse tooth segment 023 is 180° in the circumferential direction of the axis. This structure is suitable for the area where the fascia layer is thick, and can achieve maximum stimulation of the skin tissue.

[0035] In yet another embodiment, (see Figures 4-5The forward tooth section 021 and the reverse tooth section 023 are both provided with third tooth protrusions 028, the third tooth protrusions 028 are arranged between two adjacent first tooth protrusions 024 or second tooth protrusions 025, the third tooth protrusions 028 are pyramid structures, and the third tooth protrusions 028 are perpendicular to the axis of the wire body 01. The third tooth protrusions perpendicular to the axis of the wire body can fix the skin tissue in the vertical direction after the first tooth protrusions and the second tooth protrusions complete anchoring, prevent displacement of the wire body that may occur subsequently, and continuously stimulate the skin tissue.

[0036] Specifically, the protruding height of the third tooth protrusions 028 is lower than the protruding height of the first tooth protrusions 024 and the second tooth protrusions 025. Such a structure not only facilitates the sawtooth wire to be pushed into the buried line channel, but also utilizes the anchor point to fix, thereby effectively and continuously stimulating the fascia and other skin tissues.

[0037] In an embodiment, the wire body 01, the first tooth protrusions 024, the second tooth protrusions 025 and the third tooth protrusions 028 are all made of polyamide. The material can be absorbed by the skin tissue in the later period, thereby avoiding the need to remove the wire in the later period.

[0038] It should be understood that the terms "first", "second" and the like are used in the present application to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, the "first" information can also be referred to as "second" information without departing from the scope of the present application, and similarly, the "second" information can also be referred to as "first" information.

[0039] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or directly / indirectly applied in other related technical fields is included in the patent protection scope of the present application.
