Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional barb suture and positioning unit using a suture capable of uniformly spaced feeding,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a suture using three-dimensional barb forming apparatus and positioning unit capable of uniformly spaced feeding.

Sutures are used to suture wounds 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.

A conventional suture is made by cutting a certain portion from a tubular or thread-like body to form a protrusion (i.e., barb) 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.

The suture is made up of a lateral member and a barb member integrally formed in the side member, as disclosed in US 5,584,859 (Suture assembly), wherein the barb member is engaged with the body tissue and joined together with the side member It plays a role of attracting human tissue.

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

However, if the suture thread is cut in a state in which the suture thread is placed on the lower supporting member, a phenomenon may occur in which the suture is moved by the cutting blade. Particularly, 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 often pushed. In this case, the cutting can not be performed at the correct position There is also.

In addition, the barbed suture production apparatuses according to the prior art have been developed with an effective structure for forming barbs on the circumference of the suture, but there is no consideration for forming barbs at regular intervals on the circumference of the suture Improvement is required.

FIG.

Referring to Fig. 1, the sealing use three-dimensional barb forming apparatus may be configured to include a transfer unit 102, a cutting unit 104, and a positioning unit 106. [

The positioning unit 106 coupled to one side of the conveying unit 102 serves as a conveying unit for conveying the moving distance of the conveying unit 102 in advance So that barbs can be formed on the surface of the suture thread 125 fixed to the transfer unit 102 at unit intervals. In addition, the cutting unit 104 cuts the surface of the suture thread 125 to a predetermined depth in each working area of the suture thread 125, which is changed in accordance with the movement of the unit of the transfer unit 102, thereby forming a barb.

Hereinafter, each of the transfer unit 102, the cutting unit 104 and the positioning unit 106 included in the suture using three-dimensional barb forming apparatus will be described.

First, the transfer unit 102 includes a first fixing part 110, a plurality of fixing pieces 115a and 115b, a pressing part 120, a first LM guide part 130, a first supporting part 135, And may include a fastening part 140.

The first fixing part 110 is formed in the shape of a horseshoe such as "U" or "U" so that a space is formed on the inner side of the first fixing part 110, And mounting grooves for engaging the fixing pieces 115a and 115b, respectively, are formed. The pressing part 120 may be disposed on one side of the first fixing part 110 to press the one side of the suture thread 125 fixed by the fixing pieces 115a and 115b more firmly.

The first fixing part 110 is coupled to and supported by one side of the first supporting part 135 by using the first coupling part 140. The first supporting part 135 is supported by a guide mounted on the upper part of the plate- And is mounted on the upper portion of the first LM guide portion 130 to reciprocate in a unidirectional or specified number of times along a first straight path to be formed. Of course, the path formed by the guide may vary with the curved path and the like.

Further, when the first fixing portion 110 coupled to the first supporting portion 135 is moved along the first linear path by the first LM guide portion 130, the moving distance is limited so that the first fixing portion 110 is sequentially moved by a predetermined unit interval Or a positioning unit 106 for allowing the user to recognize the moving distance is coupled to one side of the first supporting part 135. [

That is, as described later, the transfer unit 102 is moved by a unit interval defined by the positioning unit 106, and then the surface of the suture 125 positioned on the work surface 145 is moved to the cutting unit 104 (I.e., barb formation), and is moved again by a predetermined unit interval when the cutting process by the cutting unit 104 is completed. The movement of the transfer unit 102 can be manually operated by the user or can be automated by using a motor or the like.

1, the first LM guide part 130, the first supporting part 135 and the first fixing part 110 are connected to each other with a suture 125 (FIG. 1) fixed to the first fixing part 110, Is positioned on the work surface 145, which is the upper surface of the work table mounted on the plate-shaped member 108, respectively.

When the first LM guide unit 130 is moved along the first linear path by the unit interval designated by the positioning unit 106, the first support unit 135 coupled to the first LM guide unit 130, 1 fixing portion 110 and the like are moved correspondingly.

The first fixing part 110 for fixing the suture thread 125 using the plurality of fixing pieces 115a and 115b and the pressing part 120 is disposed along the first straight path of the first LM guide part 130 And thus the position of the working area of the suture 125 located on the working surface 145 (i.e., the area to be barbed by the cutting unit 104, which will be described later) also changes.

In this case, the three-dimensional barb forming apparatus according to the present embodiment may include a first fixing part 110 to form a three-dimensional barb on the circumferential surface of the suture thread 125 by a cutting operation of a cutter 175 And can be combined in various forms.

That is, the first fixing part 110 may be coupled to the first supporting part 135 in a horizontal state as illustrated in FIG. 1 (first engaged state) (Second engaged state) to one side of the extended portion 610. [ 1 and 6, the first fixing part 110 is coupled to the first supporting part 135 or the extending part 610 in the inverted state (third and fourth combined state) It is possible.

Since the cutter 175 cuts the surface of the suture thread 125 in the respective engaged states, the surface of the suture thread 125 is formed with three-dimensional Barbs can be formed.

That is, the barbs are formed on the working area (i.e., the upper surface) of the suture thread 125 in the first engaged state, which is the horizontally coupled state, and the barbs are moved to the third engaged state (i.e., A barb is formed in the working area of the suture 125 (i.e., the lower surface in the first engaged state), and the state of the suture 125 is switched to the second engaged state in the vertically coupled state, (That is, the right surface in the first engaged state) of the suture thread 125 is changed to the fourth joined state (i.e., the coupled state in which the second engaged state is inverted) The barbs may be formed at various positions on the circumferential surface of the suture thread 125 (see FIG. 3 (c)). At this time, the formation interval between the barbs may be specified in advance, for example, at a unit interval designated by the positioning unit 106. [

The positioning unit 106, which adjusts the transfer unit 102 to move by a predetermined unit interval, may be formed in a toothed coupling structure as illustrated in FIG. 4, or may be formed as a ball plunger structure . Of course, it is needless to say that the structure of the positioning unit 106 that causes the transfer unit 102 to move sequentially by a predetermined unit interval is not limited thereto.

4, in which the structure of the positioning unit 106 formed in a serration structure is illustrated, the positioning unit 106 includes a spring hinge 410, a handle 415, a first latching member 420, And may include a first support member 425.

The spring hinge 410 is a hinge having a built-in spring for generating a repulsive force when a force is applied to lift one side of the center hinge and returning to an initial position when a force applied to lift one side is removed, One end of the hinge is coupled to one side of the first support 135 and the other end is coupled to one side of the handle 415. When the user lifts the handle 415 and moves the handle 415 in the direction of the first straight path, the first support portion 135 (that is, the conveying unit 415) coupled to the handle 415 via the spring hinge 410 (102) are also shifted in the corresponding directions and distances to correspond to the movement of the handle 415.

A serrated shape is formed on the whole or a part of the lower surface of the handle 415, and the serrated shape is configured to engage with a serrated shape formed on all or a part of the upper surface of the first engaging member 420. The intervals of the sawtooth shapes formed to mate with the handle 415 and the first engaging member 420 can be uniformly formed at unit intervals.

4, in order to move the transfer unit 102 coupled to the handle 415, a sawtooth forming region formed in the first engaging member 420 is formed in a sawtooth shape having a lower surface of the handle 415 May be formed longer than the forming region length.

When the user wishes to move the transfer unit 102 by a predetermined distance (for example, a unit interval), the user grasps and lifts the handle 415 and moves the handle 415 by a distance The handle 415 is lowered so that the serrations formed on the handle 415 and the lower first engaging member 420 are engaged with each other so that the suture formed by the first fixing portion 110 of the transfer unit 102, It is possible to move the position of the work area for barb formation of the bar 125. If the barbs are to be formed on the surface of the suture thread 125 at a unit interval, the user can move the handle 415 and the first engaging member 420 in the same direction, Lt; RTI ID = 0.0 > 415 < / RTI >

Using the provided spring hinge 410, the user lifts the handle 415 vertically upward, moves the first LM guide part 130 by a predetermined distance in the direction of the first linear path restricted to be moved When the handle 415 is lowered and seated on the first latching member 420, the handle 415 is fixed at that position by the force exerted by the spring hinge 410. [

The first engaging member 420 having a serrated shape in all or a part of the upper surface thereof is fixedly coupled to the first supporting member 425 fixed to the upper surface of the plate-like member 108. The first support member 425 may be formed in an "" -shaped shape to improve the supporting force as illustrated in Fig. 4, but the shape is not limited thereto.

5, where the structure of the positioning unit 106 formed of a ball plunger structure is illustrated, the positioning unit 106 includes a connecting member 510, one or more ball plungers 515, A first support member 520, and a second support member 525.

One side of the connecting member 510 is coupled to the first supporting member 135 and at least one hole is formed in the body of the connecting member 510. The ball plunger 515 is inserted into each hole. One or more holes for the ball plunger 515 to be inserted and inserted may be arranged on a virtual straight line perpendicular to the first linear direction in which the transfer unit 102 is moved as illustrated in Fig. 5, But is not limited thereto.

The ball plunger 515 has a cylindrical body, a ball is disposed at one end, and a spring for resiliently supporting the ball is accommodated in the body. That is, when a force is exerted on the ball from the outside, the ball is received inside the body, and when the external force is removed, the ball returns to the original position by the elasticity of the spring. Threads may be formed on the circumferential surface of the body constituting the ball plunger 515 so as to be easily inserted into the holes formed in the connecting member 510. [

A plurality of engaging grooves 710 (see FIG. 7) are formed on the upper surface of the second engaging member 520 to correspond to the shape and position of the ball of the ball plunger 515, (102) are formed at every unit interval to be moved.

When the ball plunger 515 inserted and fixed to the connecting member 510 is moved along the upper surface of the connecting member 510 and reaches the position of the groove corresponding to the ball plunger 515, The ball received therein returns to its original position, and therefore, when the transfer unit 102 coupled to the connecting member 510 is further moved, some resistance (i.e., a force for allowing the ball to be accommodated inside the body) is applied. Thus, the user can recognize that the transfer unit 102 has been moved by the unit interval.

For example, when the plurality of ball plungers 515 are disposed at the straight positions, the respective uniting intervals determined by the arrangement of the catching grooves 710 are not limited to the arrangement of the ball plungers 515 (See FIG. 7A). In order to further refine the unit interval in which the transfer unit 102 is moved, each of the engaging grooves 710 may be arranged in the arrangement form of the ball plungers 515 (See Fig. 7 (b)).

As compared with the case where the latching grooves 710 are arranged such that all of the ball plungers 515 provided as shown in FIG. 7A are simultaneously fixed by the corresponding latching grooves 710, When only a part of the plurality of ball plungers 515 is arranged to be fixed by the engaging groove 710 at the same time, it is possible to set a finer unit interval.

The second supporting member 525 fixes the second engaging member 520 to be stably supported and one side of the second supporting member 525 can be fixed to the upper surface of the plate member 108. [

Referring again to FIG. 1, the cutting unit 104 includes a second LM guide unit 150, a second support unit 155, a second fixing unit 160, an angle adjusting unit 165, a second coupling unit 170 And a cutter 175 as shown in FIG.

The second LM guide unit 150 is reciprocally moved along a second path formed by the guide mounted on the upper surface of the plate member 108. The second path is determined as a section on an imaginary straight line passing through the work surface 145 which is the upper surface of the work table and is set in a direction that is not parallel to the first straight path which is the movement path of the first LM guide part 130 . For example, the second linear path may be set to be perpendicular to the first linear path.

A second support portion 155 is mounted on the upper portion of the second LM guide portion 150 reciprocally moved along the second path and a second support portion 155 is provided on one side of the second support portion 155, And a second fastening part 170 for fastening the cutter 175 is coupled to one end surface of the angle adjusting part 165 opposite to the work surface 145.

The second securing portion 160 can be coupled to the second support portion 155 at a height that allows the cutter 175 to cut the top surface of the working area of the suture 125 to a specified depth.

The cutter 175 coupled to the second fastening portion 170 may be, for example, a mes that is commonly used in the medical field. There is an advantage that the cost of replacing the cutter 175 can be reduced by using the consumable material cutter 175 as a scalpel in the barb forming apparatus.

The cutter 175 is reciprocated in the direction of the work surface 145 or in the direction away from the work surface 145 as the second LM guide portion 150 reciprocates along the second path. In this process, the cutter 175 cuts the upper surface of the working area of the suture 125 positioned above the work surface 145 to form barbs on the suture surface (see Figs. 3 (a) and 3 (b)) . The reciprocating distance and / or the movement limit distance of the second LM guide part 150 may be preset so that the cutter 175 forms a barb on the surface of the suture thread 125. [

The angle adjusting portion 165 coupled to the second coupling portion 170 for fixing the cutter 175 is formed of a combination of the fixing member and the rotary member and the end portion of the fixing member is coupled to the second fixing portion 160 And a second coupling part 170 for fixing the cutter 175 is coupled to the rotary member side end.

2 (a) to 2 (d), the second fastening portions 170 (that is, the second fastening portions 170) coupled to the rotary member side end portions by the rotation operation of the rotary member (The fixed cutter 175) can be variously adjusted. The cutting angle of the cutter 175 with respect to the upper surface of the suture thread 125 can be variously adjusted so that various shapes of barbs corresponding to various purposes can be formed on the suture thread 125 surface.

6 shows a configuration of a suturing using three-dimensional barb forming device in which a first fixing part 110 is vertically joined to change a barbed surface of a suture 125. As shown in Fig.

That is, the extension part 610 is mounted on the upper side of the first support part 135 and the vertical fixing part 110 is coupled to one side of the extension part 610 using the first coupling part 140 .

The work area of the suture 125 fixed by the first fixing part 110 is positioned on the work surface 145 so that the upper surface of the work area of the suture 125 can be cut by the cutter 175. [ It is a matter of course that the height H of the extension 610 may be determined to correspond to the width W of the first fixing part 110. [

The work area of the suture 125 in which the transverse length L of the extension 610 formed in the shape of the letter "A" is fixed by the first fixing part 135 is located on the work surface 145 It is a matter of course that the length can be determined.
