Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for tying a thread to an affected area during surgery, and in particular, has a sufficient surgical field.
Threads such as deep blood vessels that cannot be obtained and are difficult to insert into the hand during ligation
The present invention relates to a surgical thread knot used for knotting.

[0002]

2. Description of the Related Art When a gallbladder or the like is operated on under a laparoscope , a hole reaching the affected area is opened in the body, a pipe is inserted into the hole, a thread is inserted into the pipe, wound around the affected area, and then taken out. It is necessary to make a knot and push the knot into the pipe with the tip of a thread knot made of an elongated metal rod to reach the affected area. However, the conventional thread knots have been dissatisfied with the fact that the thread at the tip of the thread knot slips badly and that the knot of the thread cannot be pushed and moved smoothly to perform the work smoothly.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a surgical thread knot tie capable of smoothly pushing a thread knot to the affected area and moving the same.

[0004]

To achieve the above object, the first surgical thread knot of the present invention is provided with a knot escape groove portion 2 on the distal end surface of a metal elongated rod-shaped body 1 and at both ends of the distal end. The surface is provided with a thread guide groove portion 3.

In order to achieve the same purpose, the second surgical thread knot of the present invention is provided with a thin plate-shaped slanting piece 5 at the tip of the elongated metal rod-shaped body 4 to be slanted. The thread hooking groove portion 6 is formed on the piece 5, and the inner surface 7 of the thread hooking groove portion 6 is formed as a convex curved surface with a mirror finish.

Further, in order to achieve the same object as above, in the third surgical operation thread knot of the present invention, the knot escape groove portion of the first invention is provided on the distal end surface of the elongated metal rod body 12. Instead, the thread guide groove 13 is provided on the side surface of the tip end.

[0007]

First, in the above-described first surgical thread knot, the knot of the thread is fitted into the knot clearance groove 2 of the distal end surface of the elongated rod 1, and both sides of the knot of the thread are attached to both ends of the elongated rod 1. Since it can be fitted into the thread guide groove portion 3 provided on the surface,
The knot of the thread is surely pushed by the tip surface of the elongated rod-shaped body 1.

Next, in the second surgical thread knot for the surgical operation, the inner surface 7 of the thread hooking groove portion 6 provided on the inclined piece 5 at the tip of the elongated rod-shaped body 4 is formed into a mirror-finished convex curved surface. It has very good slip and is easy to operate.

Further, in the third surgical operation thread knot, the thread knot is brought into contact with the distal end surface of the elongated rod-shaped body 12, and both side parts of the thread knot are provided on the distal side surface portion of the elongated rod-shaped body 12. Since the thread knot can be fitted into the guide groove portion 13, the knot of the thread is surely pushed and moved by the tip end surface of the elongated rod-shaped body 12.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. First, FIGS. 1 to 5 show a first embodiment of the surgical suture knot according to claim 1, wherein 1 is an elongated rod-shaped body having a diameter of 4 mm and made of stainless steel, and 2 is a tip of the elongated rod-shaped body 1. The knot escape groove portions 3 formed on the surface are thread guide groove portions formed on both side surfaces of the distal end of the elongated rod-shaped body 1 so as to communicate with both ends of the knot escape groove portion 2. In addition, 8 is a handle. As shown in FIG. 5, the knot b of the thread a is fitted into the knot escape groove portion 2, and both side portions of the knot b of the thread are fitted into the thread guide groove portions 3, respectively.

Next, FIGS. 6 to 8 show a second embodiment of the surgical ligature knot according to the first aspect. This is different from the first embodiment in that the yarn guide groove portion 3 is provided not at both ends of the knot relief groove portion 2 but at a position rotated by 90 ° in the circumferential direction. The tip of the elongated rod-shaped body 1 is tapered.

Next, FIGS. 9 to 11 show a third embodiment of the surgically-affected part thread tie according to the first aspect. This is provided with a cross-shaped knot escape groove portion 2 on the tip surface of the elongated rod-shaped body 1 and thread guide groove portions 3 provided at four locations on the outer peripheral surface so as to communicate with both ends of each knot escape groove portion 2. is there. The tip of the elongated rod-shaped body 1 is tapered.

Next, FIGS. 12 to 15 show an embodiment of the surgical thread knot of claim 2, wherein 4 is an elongated rod-shaped body having a diameter of 4 mm and made of stainless steel, and 5 is an elongated rod-shaped body 4. A thin plate-shaped slanting piece formed at the tip portion, 6 is a thread hooking groove portion formed so as to open the mouth at the tip edge of the tilting piece 5, and 7 is an inner surface of the thread hooking groove portion 6 which is mirror-finished with a convex curved surface. , 9 are handles.

Next, FIG. 16 shows an embodiment of the surgical thread knot of claim 3, wherein 12 is a slender rod-shaped member having a diameter of 4 mm and 13 is made of stainless steel, and 13 is a distal end side surface of the slender rod-shaped member 12. It is a thread guide groove portion formed in the portion. The thread guide groove portions 13 are provided at two locations (every 180 degrees) on the outer circumference of the elongated rod-shaped body 12.
Alternatively, it is preferable to provide them at four places (every 90.), but the number and position thereof are free. Incidentally, the knot clearance groove portion according to claim 1 is not provided on the tip end surface of the elongated rod-shaped body 12. The tip of the elongated rod-shaped body 12 may be tapered.

17 to 20 show working steps using the surgical ligature knot of the first embodiment of the first aspect. First, as shown in FIG. 17, the thread a is wound around the affected part c through the outer tube 10 inserted into the hole formed in the body so as to reach the affected part c, and then, as shown in FIG.
A knot b on the outside of the knot, and then the tip end of the elongated rod-shaped body 1 is applied to the knot b to put the knot b into the knot escape groove portion 2, and both sides of the knot b of the yarn a to the yarn guide groove portion 3. As shown in FIG. 19, the elongated rod-shaped bodies 1 are inserted into the outer tube 10 in the respective fitted states, and as shown in FIG. 20, the insertion is deepened until the tip surface of the elongated rod-shaped bodies 1 hits the affected area c.
The knot b is made to reach the affected part c. Incidentally, reference numeral 11 in the figure denotes a pipe inserted for looking through the affected area with a laparoscope or the like.

[0016]

The present invention is as described above. First, in the surgical suture thread knot according to claim 1, the knot b of the thread is used as the knot relief groove portion 2, and both side portions of the knot b of the thread are thread guide groove portions. Since the thread knots b can be inserted into the thread rods 3 respectively, the thread knot b can be reliably pushed and moved by the tip surface of the elongated rod-shaped body 1.
Further, in the surgical operation thread knot according to claim 2, since the inner surface 7 of the thread hooking groove portion 6 is a convex curved surface with a mirror finish, the thread can be slid well, and further, according to claim 3, In the surgical affected part thread knot, the knot of the thread may be brought into contact with the distal end surface of the elongated rod-shaped body 12, and both sides of the knot of the thread may be fitted into the thread guide groove 13 provided on the side surface of the distal end of the elongated rod-shaped body 12. Therefore, the knot of the thread is surely pushed and moved by the tip end surface of the elongated rod-shaped body 12, and in any case, there is an effect that the knot of the thread can be smoothly moved to the affected area and the affected area can be firmly tied. .
