Description

TECHNICAL FIELD [0001] The present invention relates to a suture forming apparatus, a method of forming a suture using a suture, and a method of forming a suture,

More particularly, the present invention relates to a device for forming a sewing use protrusion capable of easily forming a protrusion on a suture, a method for forming a sewing use protrusion, and a suture .

Sutures are used to combine scars in human or animal tissues such as skin, muscle, tendons, internal organs, nerves, blood vessels, and the like. These sutures are made of materials such as silk, nylon, polyester, polypropylene, or cotton, or other materials that are good in elasticity and are not easily broken inside the human body and harmless to the human body. Conventional sutures are made by cutting a certain portion from a tubular or thread-like body to form protrusions protruding from the body. These protrusions function to provide the tension necessary for pulling by increasing the binding force of the suture inside the tissue.

Such a suture is composed of a side member and a barb member integrally formed on the side member, as disclosed in U.S. Patent No. 5,884,859, wherein the barb member is attached to the body tissue and pulls the body tissue together with the side member.

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

However, if the suture thread is cut in a state where the suture thread is placed on the lower support member, the suture thread may be moved by the cutting blade in the cutting process.

In particular, when the cutting blade is repeatedly used, the cutting edge is dull and the cutting blade can not be inserted directly on the surface of the suture, and the suture is slightly pushed. At this time, the suture is pushed and bulged up in the vicinity of the cutting blade. When the suture is pushed and moved as described above, there is a problem that cutting can not be performed at an accurate position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus for forming a sealable projection according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The apparatus 10 for forming a sewing use protrusion according to an embodiment of the present invention includes a clamping mechanism 20, a lower support member 30, a cutting member 50, and an upper support member 40.

The clamping mechanism 20 clamps at least two of the suture 80 to support the suture 80. The clamping mechanism 20 is disposed on the upper side of the apparatus main body 70.

Specifically, the apparatus main body 70 includes a lower pedestal 71, a lower supporting member 30 extending upward from the lower pedestal 71, and a pair of upper and lower supporting members 30, The clamping mechanism 20 may be disposed on the upper surface side of the fixing body 72. [

The clamping mechanism 20 is constructed using a predetermined clip mechanism or the like so as to fix the position of the suture 80. The clamping mechanism 20 may be configured such that the suture 80 is lifted up by the predetermined hinge axis, The fixing pin for fixing the fixing pin can be lifted up or down. The clamping mechanism 20 is not limited to this, and may be anything other than a screw-in type, a string type that rotates around a hole, and the like, so long as the suture 80 can be detachably attached to the lower support member 30 side. Of course.

The lower support member 30 constitutes one configuration of the apparatus main body 70 and specifically has a shape protruding upward from the lower pedestal 71. The lower support member 30 has a plate shape extending along the longitudinal direction of the suture 80, and the upper end has a triangular cross section with a blunt end.

The lower supporting member 30 supports the suture 80 supported by the clamping mechanism 20 from below and the upper surface of the lower supporting member 30 is supported by the supporting surface 31 May be formed. This bearing surface 31 has a somewhat larger width than the diameter of the suture 80 and is in the form of a flat surface.

The cutting member 50 cuts a part of the suture 80 placed on the receiving surface 31 of the suture 80 to form a cutting surface for forming the protrusion 82 on the suture 80 .

The cutting member 50 includes a cutting blade 51 having a cutting surface for cutting the suture 80 and a cutting body 52 coupled to a portion opposite to the cutting surface of the cutting blade 51, And a lid 53. The cutting lid 53 is detachably coupled to the cutting body 52 and clamps the cutting blade 51 together with the cutting body 52. The coupling between the cutting lid 53 and the cutting body 52 is made by a fixing bolt 55 penetrating the cutting lid 53 and coupled to the cutting body 52.

The cutting body 52 has a rectangular shape as a whole, and a fastening groove 52a is formed at a portion where the cutting blade 51 is installed.

The upper support member 40 supports the suture 80 placed on the suture receiving surface 31 from the upper side and supports the suture 80 of the certain portion of the suture 80, And a guide surface 46 for guiding the cutting member 50 is formed so that a part of the suture 80 exposed through the exposure hole 45 can be cut by the cutting member 50 will be.

The upper support member 40 may be coupled to the lower support member 30 in a releasable manner and may be slidable with respect to the lower support member 30. [

The upper support member 40 includes a support body 41 formed with a guide surface 46 whose height decreases from one side to the other side and a cutting depth restricting portion 41 extending upward from the other side of the support body 41 42). The cutting depth limiting portion 42 limits the cutting depth so that the cutting member 50 guided through the guide surface 46 cuts the suture 80 only at a certain depth, The cutting depth of the suture 80 can be limited by contacting the suture portion 42.

The upper support member 40 has a substantially trapezoidal cross-sectional shape and extends in a direction perpendicular to the longitudinal direction of the suture 80. The suture 80 extends along the longitudinal direction of the suture 80, A slide groove 43 is formed in the upper side of the lower surface of the guide groove 41. The slide groove 43 has a shape substantially corresponding to the shape of the lower support member 30. [

The upper end of the slide groove 43 is in contact with the upper surface of the suture 80 to press the suture 80 to support the suture 80. The cross section of the contact has a triangular shape, So that the protrusion 82 of the suture 80 to be cut by the contact portion 43a can be lifted up within the contact portion 43a. On the other hand, the shape of the contact portion is not limited to this, and it may have an elliptical shape having a long axis in the vertical direction as long as the sectional area increases from the upper end to the lower end.

An exposure hole 45 formed by the slide groove 43 and the guide surface 46 is formed on the other side of the support body 41. The exposed hole 45 has a size such that a part of the suture 80 is exposed. A portion of the suture 80 exposed through the exposure hole 45 may be cut by the cutting edge 51 of the cutting member 50. [

In addition, a coupling groove 41a is formed on the lower surface of the support body 41 so as to be detachably coupled to the sliding means 60. [

The upper support member 40 slides along the longitudinal direction of the suture 80 by the sliding means 60. The sliding means (60) includes a guide rod (61) and a slider (62).

Both ends of the guide rod 61 are pivotally supported by the fixing body 72 and extend along the longitudinal direction of the suture 80 and have threads formed on the outer peripheral surface thereof.

The slider 62 slides along the guide rod 61 in a state that the upper support member 40 is mounted on the upper side and converts the rotational motion of the guide rod 61 into linear motion. A nut member (not shown) is provided inside the slider 62. The nut member is screwed with the thread of the guide rod 61 and can be moved in the longitudinal direction of the suture 80 according to the rotation of the guide rod 61. The upper surface of the slider 62 is formed with a fastening pin 62a which can detachably fix the upper support member 40 and engage with the fastening groove 41a of the upper support member 40. [

On the other hand, on the end side of the guide rod 61, a handle 63 for rotating the guide rod 61 is formed. It should be noted that the sliding means 60 is not limited thereto and may be a linear motor or the like.

The apparatus 10 for forming a sewing use protrusion according to an embodiment of the present invention has the following operational effects.

First, the suture yarn 80 requiring the shape of the protrusion 82 is placed on the suture receiving face 31 of the lower support member 30. At least two or more of the sutures 80 are then clamped by the clamping mechanism 20. Thereafter, the upper support member 40 is seated on the lower support member 30 so that the upper portion of the clamped suture 80 can be pushed. The lower surface of the upper support member 40 may be seated on the upper surface of the slider 62 and the slide groove 43 formed at the center of the support body 41 of the upper support member 40 (30). The contact portion of the slide groove 43 presses the suture 80 on the support surface 31 of the lower support member 30 while pressing the suture thread. Meanwhile, a part of the suture 80 may be exposed to the outside through the exposure hole 45 in a state where the suture 80 is pressed by the upper support member 40. Thereafter, a cutting surface of the suture 80 is cut while the cutting member 50 is slid along the guide surface 46 of the upper support member 40. The suture 80 is cut as shown in Fig. When the suture 80 is cut as described above, the protrusion 82 is formed on the surface of the suture 80.

In order to form the new protrusion 82 on the suture 80, the upper support member 40 is detached from the lower support member 30 to make the suture 80 movable, and the guide rod 61 The slider 62 and the upper support member 40 are moved to a new position and the upper support member 40 is coupled to the lower support member 30 and then the cutting member 50 is again used So that the projections 82 can be formed.

As described above, according to the sewing use protrusion forming apparatus 10 according to the embodiment of the present invention, since the upper support member 40 presses the suture yarn 80 by the contact portion on the upper side, the suture yarn 80 to be cut is effectively supported . In particular, even when the cutting blade 51 for cutting the suture 80 is bluntly worn due to a plurality of times of use, the suture 80 can be effectively cut without being pushed or stretched.

In addition, according to the apparatus 10 for forming a sewing use protrusion according to the embodiment of the present invention, since the contact portion has a triangular cross-sectional shape, the formed sewing use projection is not pressed in the contact portion 43a, It can be lifted through space.

Since the upper support member 40 is slidable by the sliding means 60, the suture 80 can be easily slid and moved so that the protrusion 82 can be easily formed on the suture 80 .

Since the cutting blade 51 is fixed by the cutting lid 53 detachably coupled to the cutting body 52 in the cutting member 50, the worn cutting blade 51 is cut from the cutting body 52, There is an advantage that it can be easily replaced by attaching / detaching only the lid 53.

7 shows a cutting member 50 according to another embodiment of the present invention in which the cutting edge 51 is bent in a curved shape. That is, the cutting surface on which the cutting is performed can be formed in a curved shape. 9 and 10, the surface of the protrusion 82 facing the suture body may have a curved cross section or a rounded shape when the cutting surface has a curved shape.

On the other hand, the shape of the cutting surface is not limited to this, and it is also possible to have a shape of a dash "∧", and the shape of the protrusions 82 produced at this time may also have a corresponding shape.

11 shows a protrusion forming apparatus 10 according to an embodiment of the present invention. In the protrusion forming apparatus according to FIG. 11, the protrusion forming apparatus 10 shown in FIG. A projecting pin 54 is formed in the cutting member 50. [ That is, two projecting pins 54 may be formed on the side surface of the cutting member 50 so as to be spaced apart from each other.

The upper support member 40 may be provided with a slot 44 for guiding the projecting pin 54 of the cutting member 50. That is, according to the projection forming apparatus 10 shown in Fig. 11, the projecting pin 54 can be guided by the slot 44 to form a cutting path. At this time, the slot 44 has a first slot portion 44a extending in a linear shape in one direction, a second slot portion 44b extending from the first slot portion 44 and forming an inclination angle from the first slot portion 44a, (44b). At this time, the inclination angle of the second slot portion 44b may be smaller than the inclination angle of the first slot portion 44a (angle from the horizontal plane). That is, the second slot portion 44b may have a gentle inclination angle.

According to the sewing use projection forming apparatus 10 shown in Fig. 11, as shown in Fig. 12, the angle formed by the sewing yarn 80 and the cutting member 50 at the cutting start position (see Fig. 11 (a) the angle? 2 formed by the suture 80 and the cutting member 50 at the cutting completion position may be different from each other. Specifically,? 1>? 2. That is, the cutting member 50 inserted with a cutting slope suddenly enters the cutting section after a certain period of time to perform cutting. In the case of insertion with different cutting inclination, the sewing use protrusion can be reliably lifted. In other words, in the case of the protrusion 82 which is simply inserted in one direction, the protrusion 82 may be laid again or returned to the original position. However, when the protrusion 82 is cut at an additional angle as shown in FIG. 11, It will be possible.

The suture using projection forming apparatus 10 according to the present invention can be modified as follows. For example, in the above-described embodiment, the contact portion is in the form of a triangle. However, the present invention is not limited thereto. In the case where an additional space is formed inside the protrusion 82 in addition to the circular cross- It goes without saying that various forms are possible.

In the above-described embodiment, the cutting surface is cut while maintaining the cutting surface in a direction orthogonal to the longitudinal direction of the suture 80, but the present invention is not limited thereto, and the suture 80 may be cut obliquely at an oblique angle It is also possible.

First, in the above-described embodiment, the movement of the upper support member 40 has been described. However, the present invention is not limited to this, and it is also possible for the suture thread to move relatively. For example, as shown in FIG. 13, a suture 80 is wound on a roll 90 that is rotatably coupled to a fixture 72, and as the roll 90 rotates, It is also possible to go back and forth. At this time, the upper support member 40 may be in a fixed state.

In addition, in the above-described embodiment, the movement of the suture thread, the cutting operation of the cutting member 50, and the separation and coupling of the upper support member 40 are all manually performed. However, the present invention is not limited thereto. It is also possible to do.

In addition, the cutting blade 51 of the cutting member 50 is provided with at least one through hole, a fixing structure (disposable blade structure) penetrating the through hole as an elastic material, and a straight outer force transmitting engagement member A structure that allows parallel movement by pushing with a finger or the like).

The suture 80 according to an embodiment of the present invention includes a suture body 81 and a projection 82 formed integrally with the suture body 81 and formed by cutting the suture body 81 The surface of the protrusion 82 facing the suture body may have a curved cross section or a rounded shape.

In addition, the angle formed by the protrusion 82 of the suture 82 and the opposite surface of the suture body may be different from each other at the tip of the protrusion 82 and the attached portion of the suture body.

In addition, the angle formed between the face of the protrusion 82 facing the body of the suture and the opposite face is defined as? 1, and the face of the protrusion 82 facing the body of the suture is attached to the suture body, And the angle formed by the opposite surface is? 2,? 1>? 2.

A method of forming a suture using projection of a lower suture member according to an embodiment of the present invention includes a step of placing a suture on a support surface 31; A suture clamping step of clamping at least two or more of the sutures; A suture pressing step of pressing the upper part of the clamped suture by the contact part of the upper support member 40; And cutting a portion of the suture using a cutting member 50 so that the protrusion 82 is formed on the suture.

At this time, the cutting step may be such that a part of the suture is cut into a circular shape or a round shape.

The cutting step may be performed such that the initial angle between the suture thread and the cutting member 50 at the initial cutting stage for cutting the suture thread and the final angle between the suture thread and the cutting member 50 at the final stage of cutting the suture thread are different from each other You can cut it.

On the other hand, when the suture of the present invention is packaged in a form other than a roll, the suture is difficult to be processed due to severe deformation, and even if the suture is processed, the suture is severely deformed and the final result is not good. It is also possible to treat the suture using a separate oven . For example, prepare a separate oven, preheat the oven at 150 ° C for 5 minutes, and allow the suture application room to react in the oven for 1 minute. Thus, the process of putting into the oven for treatment and disinfection can be added. However, it goes without saying that the preheating time of the oven, the temperature, and the reaction time of the sealing chamber may be varied according to the conditions of the person skilled in the art.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, .
