Abstract

Disclosed is a surgery thread having a plurality of barbs formed to protrude from a surgery thread body by partially cutting the surgery thread body from the surface to the inside thereof. In a cutting cross-sectional view of each of the barbs cut along a line extending from a central point of the bottom side to the vertex of each thereof, a cut line of each of the barbs is formed in a circular arc shape. Each of the barbs of the surgery thread according to the present invention has a curved cut surface, so the base part of each of the barbs is formed to be thick and can receive power. Accordingly, when being inserted in human tissue such as skin, the surgery thread has excellent sticking properties and tensile force with respect to tissue. Moreover, the end part of each of the barbs is formed to be soft, and thus can be inserted and used in a shallow region of skin, so surgery side effects do not occur. Also, the barbs can be formed just by rotating a blade within a predetermined range, so the surgery thread can be easily produced.

Description

{Thread For Surgery}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a surgical thread, and more particularly, to a cosmetic thread for improving deflection of skin and muscles by holding a plurality of barbs formed by cutting in a circular arc direction, that is, for lifting.

BACKGROUND OF THE INVENTION Sutures have been used in which barb is formed to connect tissues to heal wounds in human or animal tissues such as skin, muscle, tendons, internal organs, nerves, blood vessels and the like.

Japanese Unexamined Patent Application Publication No. 10-2005-0065568 (published on June 29, 2005), Japanese Patent Application Laid-open No. 10-2005-0094394 (published on September 27, 2005), Japanese Patent Application Laid-Open No. 10-2012-0007543 (2012. (Japanese Unexamined Patent Application, First Publication No. H10-120,205), Japanese Patent Application Laid-Open No. 10-2005-0060081 (published on May 21, 2005), Japanese Patent Application Laid-open No. 10-2013-0091662 And the barb is cut straight to the inner surface to form a barb.

On the other hand, Japanese Patent Application Laid-Open No. 10-2008-0039345 (published on May 05, 2008, 2008) discloses a suture having an angled barb by sloping the suture body from the surface to the inner surface and then shaving horizontally. However, this suture has disadvantages in that the tensile strength of the thread is lower than that of the suture that forms the barb with only the oblique line.

Patent Registration No. 10-1258888 (registered on Mar. 23, 2013) discloses a fixing suture in which the end of the barb is formed into a cobra shape. This patent describes that the bar cutting end is in the direction of the longitudinal axis or parallel to the surface of the short fiber suture so that the stress is not concentrated and dispersed so that a significant reduction in the tensile strength of the short suture is prevented It is not easy to form the cobra-shaped barb end by a cutting method, and it is actually possible to perform injection molding with a mold.

Patent Registration No. 10-1057377 (Registered on Aug. 10, 2011), Patent Publication No. 10-2013-0069172 (Published on Mar. 26, 2013), Patent Registration No. 10-1057376 (Issued on Aug. 10, 2011 (Registered trademark), etc., disclose an example of forming barbs of a suture by injection molding.

When the barbs are formed by injection molding, the ends of the barbs become hard and the barbs become less bent and have a force. This rigidity of the barb can be touched on the surface of the skin when it is inserted shallowly into the skin. In order to avoid such discomfort, the suture is inserted into the skin deeply. In such a case, the following problems arise. In other words, since the blood vessels, nerves, fascia, etc. are present in the deep part of the skin more than the surface of the skin, the aftereffects of the surgery may become serious. In addition, it is disadvantageous in terms of cost to form barbs by injection molding as compared to forming barbs by cutting sutures.

Patent Publication No. 10-2009-0007421 (published on Jan. 16, 2009) discloses a suture having a barb having a deeper barb cut depth at the center of the barb than the barb cut depth at the base of the barb. However, these barbs are not easy to form.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems of the prior art. Accordingly, an object of the present invention is to provide a surgical thread having barbs which are excellent in fixation to tissues when inserted into body tissues such as skin and have excellent tensile strength of the whole thread and are easy to manufacture.

An object of the present invention is to provide a surgical thread manufacturing apparatus which is simple in structure and can be manufactured by a simple method.

According to an aspect of the present invention, there is provided a surgical staple according to the present invention including a plurality of barbs formed to partially protrude from a surface of a surgical chamber main body and partially cut off the surgical chamber main body from the surface of the surgical chamber main body. In this surgical barrel, the barb is a shape in which the cutting line of the barb is formed as an arc in a cutting sectional view in which the barb is cut along a straight line connecting the center point of the base of the barb and the vertex of the barb.

It is preferable that the ratio of the cutting depth D of the barb to the diameter SD of the surgical chamber main body, that is, D / SD is in the range of 0.1 to 0.4.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 to 5, a surgical chamber 10 according to the present invention includes a surgical chamber main body 100 and a plurality of barbs 200. The barb 200 is formed to protrude from the surgical chamber main body 100 by partially cutting the surgical chamber main body 100 from the surface of the surgical chamber main body 100 to the inner surface thereof. In the surgical bar 10 of the present invention, the barb 200 is a straight line connecting the center point 213 of the base 210 of the barb 200 and the barb 220 as shown in FIG. Sectional view (FIG. 2) in which the barb 200 is cut along the line A-A 'of FIG. 2, the cutting line 240 of the barb is formed as an arc.

Therefore, in the surgical chamber 10 of the present invention, the barb 200 has a back surface formed by curving. 3, after the barb 200 is cut and the barb 200 is formed, the barb 200 protrudes from the surgical chamber 100, and thus the barb 200 is exposed to the outside do.

In the present specification, the barb 210 of the barb is referred to as a line segment connecting the two points 211 and 212 forming the base of the barb at the surface of the surgical chamber main body 100, as clearly shown in Fig. 1 . Also, the vertex 220 of the barb is formed at the most proximal portion of the cutting line formed on the surface of the surgical chamber main body 100, as clearly shown in Fig.

As described above, the surgical chamber 10 according to the present invention is formed by cutting horizontally after cutting into obliquely and in comparison with the prior art surgical bar having a barb formed by cutting the oblique line, that is, In contrast to the prior art surgical thread having a barb having a barb having the barb as a back side, the barb having a curved side has a curved surface, so that when cutting the barb at the same angle to form a barb, The base portion is formed thicker and can exhibit a resistance to a large force. That is, when the composition is inserted into a body tissue such as skin, it is excellent in fixation to the tissue. In addition, as compared with the prior art surgical thread having a barb having a plane as a back surface, the barb is formed by cutting a slant line and cutting it horizontally The pulling force exerted on the entire thread is superior to that of the prior art surgical thread having the barb having the barb, that is, the inclined plane and the horizontal plane as the back side.

The surgical chamber 10 according to the present invention is not required to introduce a metal mold as compared with the prior art surgical chambers in which barbs are formed by injection molding, Is simple and easy to use. In addition, since the surgical thread 10 of the present invention is excellent in fixation to body tissues such as skin, it is possible to insert it shallowly into the skin because the end of the barb is smoothly formed, and there is also an advantage that there is less possibility of postoperative complications.

Therefore, the surgical chamber 10 of the present invention forms a stable structure by forming the base of the barb to be thick, thereby improving the fixability to body tissues such as the skin, etc., as well as forming the barb into an arc shape, (SD) reduction of the main body is small and the tensile force reduction of the thread is small. The surgical thread 10 of the present invention having such an advantage is particularly suited as a cosmetic thread for improving deflection of the skin and muscles, that is, for lifting.

In order to better demonstrate the advantages of the surgical thread 10 of the present invention as described above, that is, the advantages of being simple and easy to manufacture while maintaining excellent fixation and tensile strength to body tissues, 10) is preferably optimized as follows.

First, the ratio of the cutting depth D of the barb to the diameter SD of the surgical chamber in the surgical chamber 10 of the present invention, that is, D / SD is in the range of 0.1 to 0.4, It is preferably in the range of 0.2 to 0.3.

The cutting angle? Of the barbs is preferably 10 to 45 degrees, more preferably 15 to 30 degrees. Herein, the cutting angle? Of the barb means the angle formed by the tangent line and the barb surface line 230 when the tangent line is tangent to the arc 240, which is the arc at the vertex 220 of the barb.

Also, the ratio of the length (L) of the barb to the cutting depth (D) of the barb, that is, L / D is preferably 1.5 to 4.5, more preferably 2 to 3.5. Further, the distance P between the barb and the adjacent barb to the diameter SD of the surgical chamber body is preferably 1.5 to 4.5, more preferably 2 to 3.5. Here, the distance P between the barb and the neighboring barb can be defined as the distance between neighboring barb apexes or the distance between the barb base points if the barb is formed on the same straight line, and the barb is formed on the same straight line Otherwise, it can be defined as the distance between adjacent vertexes of a barb or the center-of-barb point of a barb after a certain barb is translated parallel to a line formed by neighboring barb. In FIG. 1, the barb 200 is shown by a dotted line, which is not formed on the same straight line as the neighboring barb 200, so that it is first moved in parallel to the barb shown in solid lines and then the distance between the barb and the neighboring barb (P).

The surgical bar 10 of the present invention may be formed such that a plurality of barbs 200 are formed only on a single virtual straight line on the surface of the surgical barrel body 100. However, Or may be formed on the first virtual straight line on one surface of the main body 100 and on the second virtual straight line on the opposite surface of the first virtual straight line. In this case, the spiral angle of the barb on the first virtual straight line and the barb on the second virtual straight line is 180 degrees. The opposite barbs 200 may be symmetrical with respect to the central axis of the surgical chamber main body 100, but may be arranged in a staggered shape, i.e., in a zigzag form, as shown in Fig. The surgical barrel 10 having the barbs 200 in a zigzag shape as shown in Fig. 4 is smaller in diameter than the barbs 200 having symmetrical barbs 200 in diameter, Is relatively large, so that the tensile force is better. In addition, the barbs may be formed in the same manner as described above on three virtual straight lines or on four virtual straight lines. In this case, the spiral angles of the barbs are 120 degrees and 90 degrees. The barb 200 may also be formed on an imaginary curve formed on the surface of the surgical chamber main body 100 in a spiral shape without being formed on an imaginary straight line. In this case, it may be formed as a single spiral, a double spiral, a triple spiral, and a quadruple spiral.

FIG. 5 schematically shows the whole of a surgical room according to an embodiment of the present invention. Referring to FIG. 5, the entire length of the surgical chamber may be about 10 to 100 centimeters, preferably about 10 to 50 centimeters, and more preferably about 30 centimeters. The type and form of the thread are not limited as long as they are normally usable as a surgical thread, whether it is a biodegradable thread or not. The thickness of the yarn can be applied if the thickness is about 5-0, 4-0, 3-0, 2-0, 1-0, 0, 1 and 2. The surgical thread has a central, non-barb area 120 without a barb at its center, which can be as long as about 1 to 4 centimeters in length. The surgical thread also has barb-free end-barb areas 130 and 140 at the ends of the socks, the length of which can be less than 10 centimeters in length. In the surgical chamber 10 of the present invention, it is preferable that the barbs 200 are formed in opposite directions to each other about the center non-barb area 120, particularly in the directions opposite to each other as shown in FIG.

Next, referring to Fig. 6, an apparatus for manufacturing the above-mentioned surgical chamber 10 of the present invention will be described.

The surgical-thread manufacturing apparatus 20 according to the present invention has a mounting portion for mounting a surgical thread as shown in Fig. The blade 400 is mounted perpendicular to the longitudinal direction of the surgical chamber.

And a guide part 300 for guiding the guide part 300. The guide portion 300 includes a cylinder having an inside diameter slightly larger than the thickness of the surgical chamber.

The blade 400 may be of a plate-like shape having a rectangular surface, and has a sharp acute-angled blade shape at a corner portion contacting the surgical chamber. The blade 400 is disposed at a position somewhat distant from the surgical chamber to facilitate mounting of the surgical chamber in a non-operating state, and is disposed at a position such that the blade 400 is substantially in contact with the surface of the surgical chamber Prepare to operate. The blade 400 is rotated in a predetermined range in the vertical direction to partially cut the surgical chamber main body from the surface of the surgical chamber main body and to project a plurality of barbs from the surgical chamber main body, Shaped barbs. Here, the blade 400 is rotated in a predetermined range in the up-and-down direction. The blade 400 is disposed on the upper portion of the surgical chamber, rotates at a predetermined angle from the upper portion to the lower portion, . In addition, the angle formed by the blade with respect to the surgical chamber is the cutting angle (?) Of the barb as described above, and the blade 400 is barbed and rotated in the circular arc direction when the surgical chamber main body is partially cut.

In order to enable this operation of the blades, that is, to rotate in a predetermined range, the manufacturing apparatus 20 of the present invention includes the blade rotating means 500. The blade rotating means 500 includes, for example, a driven gear 510 disposed to surround the extended portion of the blade 400, a driving gear 520 for transmitting power to the driven gear, and a motor Not shown). As shown in Fig. 6, the driven gear 510 rotates in the B direction.

The manufacturing apparatus 20 of the present invention further includes a longitudinal thread moving means (not shown) for moving the surgical thread in the longitudinal direction. The longitudinal directional thread moving means may be formed such that the operating room fixing part for holding the surgical thread at the end of the sock of the surgical thread moves in the longitudinal direction of the thread. Meanwhile, the longitudinal thread moving means may be means for winding, loosening or moving the surgical thread at the end of the suture of the surgical thread separately from the operating chamber fixing means for holding the surgical thread at the end of the thread of the surgical thread. At this time, the operating room fixing part should release the operating room fixing when the operating room moves. When one barb forming operation is completed, the surgical thread is moved by a predetermined length in the D direction as shown in Fig. 6 by the longitudinal thread moving means, and the next barb forming operation is performed, Can be formed. On the other hand, since the longitudinal direction moving means can be a structure which is commonly employed in mechanical devices, a detailed description thereof will be omitted.

Here, the vertical direction and the left-and-right direction indicate the direction of the surgical chamber in the longitudinal direction. That is, as shown in FIG. 6, it means the C direction. The left and right blade moving means 600 serves to adjust the position of the blade 400 so that the surgical thread is positioned in the center of the blade 400. In the meantime, since the left and right blade moving means 600 can be of a structure that is commonly employed in mechanical devices, a detailed description thereof will be omitted.

The manufacturing apparatus 20 of the present invention may further include a rotating direction blade moving means 700 for rotating the blade 400 about the longitudinal direction of the surgical chamber. The rotating direction blade moving means 700 is operated when the barb is formed on two or more virtual straight lines or on a spiral virtual curved line rather than being formed on only one imaginary straight line on the surface of the surgical room body As shown in Fig. 6, the blade 400 is rotated in the A direction. Meanwhile, since the rotating blade moving means 700 can be of a structure that is commonly employed in mechanical devices, a detailed description thereof will be omitted.

As described above, the manufacturing apparatus 20 of the present invention is economical and convenient because it makes it possible to manufacture the surgical chamber described above in a simple configuration and operation manner.
