First, the housing 110 forms a path within the housing 110 through which the wire W can pass. In addition, the housing 110 also provides a space where the first control unit 130 and the second control unit 140 can be mounted.

As shown in FIG. 2, the housing 110 includes a first seating groove 111 in which the first manipulation unit is provided; a second seating groove (112) connected in communication with the first seating groove (111) and in which the wire (W) passing through the first seating groove (111) is disposed; A hollow hole 113 connected in communication with the second seating groove 112 and in which the second manipulation unit 140 is provided; and a third seating groove 114 connected to the hollow hole 113 to enable communication, and into which the longitudinal end of the catheter 120 is inserted and placed.

The first seating groove 111 provides a space where a pair of first handles 131 of the first manipulation unit 130, which will be described later, can be rotatably mounted.

The second seating groove 112 is arranged in a direction parallel to the longitudinal direction of the housing 110, and serves to connect the first seating groove 111 and the hollow hole 113 to each other.

The hollow hole 113 provides a space where the second handle 141 of the second manipulation unit 140, which will be described later, can be rotatably mounted, and the user can easily operate the second handle 141. It serves to expose a portion of the second handle 141 to the outside of the housing 110 so that it can be removed.

The third seating groove 113 allows the wire (W), which sequentially passes through the first seating groove 111, the second seating groove 112, and the hollow hole 113, to be guided into the interior of the catheter 120. It serves to stably support the longitudinal end of the catheter 120.

Since the housing 110, which forms the above-mentioned space inside, is a component that is held by the user's hand, it is desirable to have a size and external shape that make it easy to hold with one hand.

In addition, through-holes capable of communicating with the outside are formed on one longitudinal side and the other side of the housing 110, and the longitudinal end of the catheter 110 passes through the through-hole formed on one side, and a wire ( W) can be passed.

The catheter 120 is a component that is inserted into the patient's body, and its tip is sharply processed. A wire W may be passed inside the catheter 120, and a guide portion 142, which will be described later, may be inserted.

In one embodiment of the present invention, the distal end of the catheter 120 is shown in the drawing as having a straight shape, but it is not limited thereto. For example, the distal end of the catheter 120 may be bent at various angles such as approximately 35 degrees, 45 degrees, or 90 degrees depending on the surgical site.

The first manipulation unit 130 is rotatably mounted on the first seating groove 111 with the wire W disposed inside the housing 110 in between, and is in contact with the wire W. It may include a pair of first handles 131 that are rotated to move the wire W forward or backward.

The first handle 131 has a circular roller shape and, as described above, can be disposed on both sides of the wire W. And, a rotation axis inserted into the hole formed in the first handle 131 protrudes from the first seating groove 111 where the first handle 131 is provided.

The first handle 131 may be made of various materials such as plastic, metal, and rubber, and is made of plastic that exhibits elastic restoring force to prevent damage to the wire (W) during rolling contact with the wire (W). It is preferable that it is made of ash, rubber material, or urethane material.

Additionally, friction protrusions may be formed on the circumferential surface of the first handle 131 to generate contact friction with the wire W.

Meanwhile, as shown in FIG. 1, a portion of the first handle 131 is exposed to the side of the housing 110, and the user rotates the exposed first handle 131 to use the wire W. It can be moved forward or backward.

Accordingly, when the user rotates the first handle 131 disposed on one side of the pair of first handles 131 in one direction, the remaining first handle 131 may be rotated in the other direction. Then, the wire W disposed between the pair of first handles 131 can be advanced while contacting the outer peripheral surface of the pair of first handles 131. Conversely, when the user rotates the first handle 131 disposed on one side of the pair of first handles 131 in the other direction, the remaining first handle 131 may be rotated in one direction. Then, the wire W disposed between the pair of first handles 131 may be moved backward while contacting the outer peripheral surface of the pair of first handles 131.

As shown in FIGS. 1 to 5, the second manipulation unit 140 is rotatably mounted on the inner portion of the housing 110 dividing the hollow hole 113, and the wire (W) A hollow second handle 141 forming a space inside that can be passed through; and a guide bar 142 whose longitudinal end is fixedly mounted in the inner space formed in the second handle 141 and whose longitudinal other end extends into the interior of the catheter 120.

The second manipulation unit 140 configured as described above rotates the wire W disposed inside the housing 110 and the catheter 120 to rotate the ring R exposed at the tip of the catheter 120. It plays a role.

The second handle 141 rotates in a direction perpendicular to the rotation center axis of the first handle 131, and is composed of a pair of casings each having a semi-cylindrical shape with a space formed therein, coupled to each other. do. In addition, as shown in FIG. 4, the inner surface of the pair of casings constituting the second handle 141 has a protruding member 141a extending toward the wire W passing through the hollow hole 112. It is prepared.

The protruding member 141a may be considered a component coupled to one end of the guide bar 142 in the longitudinal direction. That is, one longitudinal end of the guide bar 142 may be mounted between the protruding members 141a in each pair of casings. A groove (not shown) through which the wire W can pass is formed in the protruding member 141a so as not to interfere with the linear movement of the wire W. For reference, in FIG. 4 , one casing among a pair of casings constituting the second handle 141 is omitted from illustration in order to show the internal structure of the second manipulation unit 140.

As shown in FIGS. 4 and 5, the guide bar 142 is interposed between the pair of protruding members 141a, and is located at the longitudinal portion of the wire W passing through the hollow hole 113. Head (142a) in contact with; And an extension member (143b) extending from the head (142a), inserted into the interior of the catheter (120), and in contact with the longitudinal portion of the wire (W) passing through the interior of the catheter (120). can do.

The guide bar 142 configured as described above is in contact with the hollow hole 113 and the longitudinal portion of the wire W disposed inside the catheter 120 and the second handle 141. It can be said to be a component that rotates together to rotate the ring (R) formed at the tip of the wire (W).

The head 142a of the guide bar 142 has a width greater than the diameter of the wire W, and can be combined with the above-described protruding member 141a. The head 142a is formed with a through hole into which a coupling protrusion (not shown) formed on the protruding member 141a can be inserted. For reference, among the pair of protruding members 141a, a coupling protrusion is formed on one of the protruding members 141a, and the other protruding member 141a has an insertion hole into which the coupling protrusion can be inserted in an interference fit manner. is formed, and the insertion hole may correspond to a through hole formed in the head 142a. Therefore, when the coupling protrusion formed on the protruding member 141a passes through the through hole formed on the head 142a and is inserted into the coupling hole formed on another protruding member 141a in an interference fit manner, the head of the guide bar 142 is inserted into the coupling hole formed on the head 142a. It can be fastened to a pair of protruding members (141a).

The extension member 142b has a width larger than the diameter of the wire W and smaller than the width of the head 142a, and is inserted into the catheter 120 as described above.

The extension member 142b may be in contact with a longitudinal portion of the wire W disposed in the inner space of the catheter 120 in order to rotate the wire W disposed in the inner space of the catheter 120.

Therefore, when the user rotates the second handle 141 in one direction or the other direction while holding the housing 110, the wire W disposed inside the housing 110 and the catheter 120 can be rotated. there is.

Then, as shown in FIGS. 6 and 7, the suture t inserted into the ring R can be changed into a shape that is easy to form a knot by rotating the ring R. In this state, when the user operates the first handle 131 of the first manipulation unit 130 to retract the wire (W), the ring (R) will be inserted into the internal space of the catheter 120 together with the suture (t). You can.

At this time, the ring (R) may be compressed elastically by being pressed against the inner peripheral surface of the catheter 120. In this state, the catheter 120 can be inserted into a muscle, ligament, or soft tissue to deliver the suture t.

In addition, since the suture t can be changed into a shape to form a knot by rotating the ring R, there is a need to flow the catheter 120 in various directions inside the patient's body in order to tie the suture t. There is no Therefore, it is possible to prevent the problem of unintentionally damaging muscles or soft tissues other than the surgical area.

For reference, the wire W may be made of monofilament or nitinol. And, the ring R formed by the wire W preferably has the shape of a roughly diamond-shaped noose, as shown in FIG. 6. This is because it can be easily inserted into the catheter 120 and is in a form that facilitates elastic restoration.

Meanwhile, the wire W passing through the interior of the housing 110 and the catheter 120 may be two strands. In practice, one wire (W) may be used, but since the ring (W) is formed with one wire (W), the wire (W) disposed inside the housing 110 and the catheter 120 is It can be said to be two strands.

As shown in FIG. 8, the two wires (W) disposed inside the housing 110 and the catheter 120 are divided into two by the guide bar 142 in the area where the guide bar 142 is placed. It branches off and becomes non-contact. At this time, one of the two wires W is in contact with one side of the guide bar 142, and the other wire W is in contact with the other side of the guide bar.

Conversely, the two wires W passing through the inside of the housing 110 where the guide bar 142 is not disposed and the inside of the catheter 120 may be in contact with each other.

Accordingly, the wire W disposed inside the housing 110 and the catheter 120 can be instantly rotated in conjunction with the rotation of the guide bar 142.

In addition, as shown in FIGS. 5 and 8, the head 142a of the guide bar 142 has a cut groove 142c into which the two wires W in contact with each other can be inserted and fixed. This can be provided. Accordingly, the two strands of wire W can be maintained in close contact with the head 142a and the extension member 142c of the guide bar 142.

Although specific embodiments of the present invention have been described so far, it goes without saying that various modifications are possible without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the patent claims described below as well as equivalents to the claims of this patent.
