Description

Suture for surgical and facial lift

The present invention relates to a suture for surgery and face lift, and more particularly, it is manufactured by pressing the suture with a mold to form a protrusion, so that the stability of the knot, fixation power and binding force can be improved when used in procedures, surgeries and face lifts, etc. It relates to sutures for use in surgery and face lift.

Sutures have been used for a long time to connect or suture damaged muscles, blood vessels, nerves, tissues, or wounds or surgical incisions. In addition, sutures are also used for double eyelid surgery, aging, skin elasticity reduction, trauma, overuse, necrosis, and the like to remove tissue or skin sagging, wrinkles, and the like. The lifting procedure using sutures is a technique that lifts sagging skin and tissues of the face, chin, neck, abdomen, vagina, chest, hips, etc., and pulls and straightens wrinkles without using a knife. No incision is required, scarring can be minimized, and there is less bleeding or swelling due to surgery, which is attracting attention.

Recently, sutures with protrusions (barbs, barbs, cogs) formed on the outside of the surface have been developed and used. Since they have non-slip properties due to the protrusions, they have the advantage of not being easily unraveled after suturing.

One of the important points to consider in a procedure using a suture is that it is necessary to firmly hold and fix the suture at the treatment site in order to ensure the suture, tissue adhesion, support, and fixation effect are stable and long-lasting. A strong knot device is needed to prevent this from unraveling, and it is necessary to reduce the time and effort required for the knotting process to a minimum for a quick and safe operation.

Such a suture is made of a side member and a barb member integrally formed on the side member as disclosed in US Patent No. 5,584,859, wherein the barb member catches the human tissue and pulls the human tissue together with the side member.

The barb member formed on the suture is manufactured by placing the suture on the upper surface of the lower support member and cutting the surface of the suture by a predetermined cutting mechanism while fixing the suture with a clamping mechanism.

However, the conventional method of manufacturing a suture as described above has a disadvantage in that it takes a lot of time to manufacture, because the surface of the suture is cut in a predetermined portion to manufacture a barb member, that is, a protrusion, and thus productivity is low.

Specifically, the body 10 may be formed to have a circular front cross-section and to have a length. That is, it is a portion other than the protrusion 20 formed while the outer side is cut by the mold.

At this time, the body 10 may have a diameter (D) of 0.25 to 0.35 mm, preferably 0.3 mm.

This is because it has a size suitable for being inserted into the skin while having a force that can support the protrusion 20 to some extent.

The protrusions 20 are spaced apart at a predetermined angle (α) along the outer circumferential surface of the body 10 and are formed in a protruding shape to form a plurality of protrusions.

Here, the plurality of protrusions 20 are formed to be spaced apart at an angle α of 90° along the outer circumferential surface of the body 10, and may be formed to be spaced apart at _{regular intervals (L 1 ) along the longitudinal direction.} In this case, the predetermined angle α of the protrusion 20 may be formed at an angle of 120° or 180° in addition to the angle of 90°, which will be described in the second to third embodiments.

These protrusions 20 are formed so as to protrude outward from the body 10, in which case the maximum protrusion length (L ₂ ) of the protrusions 20 from the body 10 may be 0.25 to 0.35 mm, and it is 0.3 mm. desirable.

At this time, when the maximum protrusion length (L ₂ ) of the protrusion is less than 0.25 mm, the fixing force to the skin tissue may be lowered, and if it is more than 0.35 mm, the protrusion 20 may not be able to withstand the force sufficiently, and a situation in which the protrusion 20 is laid down may occur.

At this time, since the protrusion 20 protrudes obliquely to the outside, the protrusion length of the protrusion 20 may be formed to be 0.35 mm or less, and may be formed to be 0.3 mm or less.

More specifically, the protrusion 20 may include a first inclined portion 21 and a second inclined portion 22 .

The first inclined portion 21 may have one end inclined upward from the body 10 to the other side.

The second inclined portion 22 may be formed to be inclined downward from the first inclined portion 21 to one side of the body 10 .

Accordingly, the protrusion 20 may have an inner angle β and an outer angle γ.

First, the inner angle β of the protrusion 20 is an angle between the body 10 and the second inclined portion 22, and may be formed in a range of 25 to 65°.

In addition, the outer angle γ of the protrusion 20 is an angle formed by the first inclined portion 21 and the second inclined portion 22 , and may be formed to be 2 to 18°.

Through this, the insertion of the suture into the skin can be made easily and firmly fixed to the skin tissue.

Here, except for the pattern in which the protrusion 20 is formed, the suture 1 for surgery and face lift according to the third embodiment of the present invention is the suture for surgery and face lift according to the first embodiment described above. It is substantially the same as (1).

Accordingly, only the pattern in which the protrusions 20 are formed on the body 10 will be described.

The protrusions 20 are spaced apart at an angle of 180°, which is a predetermined angle α, along the outer circumferential surface of the body 10, and are formed in a protruding shape to form a plurality of protrusions.

In this way, when the predetermined angle α of the protrusion 20 is formed at an angle of 180°, it may be formed in two patterns.

First, as shown in (a) of FIG. 7 as an example, a plurality of projections 20 are formed to be spaced apart at an angle α of 180° along the outer circumferential surface of the body 10, and 1.5 mm along the longitudinal direction. It may be formed to be spaced apart at a predetermined interval (L _{1 ) of 3.5 mm to.}

_{In other words, a plurality of projections 20 are formed spaced apart at a predetermined interval (L 1} ) of 1.5 mm to 3.5 mm along the longitudinal direction of the body 10, and an angle of 180° between adjacent projections 20 (α) ) may be formed to be spaced apart.

A pattern may appear as if formed as described above so that the protrusions 20 are formed in a zigzag shape on both sides of the body 10 .

First, as an example, as shown in FIGS. 11 and 12 , the microprotrusions 23 may be formed to be inclined upward from the first inclined portion 21 to one side. That is, the protrusion 20 is the same shape but smaller and protrudes in the opposite direction.

As such, since the fine protrusion 23 protrudes in the opposite direction to the protrusion 20 and acts in the opposite direction, the traction force and fixation force of the suture 1 for surgery and face lift can be further improved.

Next, in this example, as shown in FIGS. 13 and 14 , the microprotrusions 23 are formed in lengths on both sides, and may be formed in a concave arc shape in lateral cross-section. That is, the two microprotrusions 23 have curvatures on one side and the other side, are formed symmetrically to each other, and may be formed to have lengths on both sides.

As such, the fine protrusions 23 are formed and act in the same direction as the protrusions 20 and also act in the opposite direction, thereby further improving the traction and fixation force of the suture 1 for surgery and face lift.

The microgrooves 30 are preferably formed in a coiling shape along the outer circumferential surface in the longitudinal direction in the body 10, but are not limited thereto, and may be formed in other shapes such as a plurality of rings in addition to the coiling shape. can
