Abstract

PROBLEM TO BE SOLVED: To provide a ligator with features that a thread would not come off from its tip and can be put back to a status of being hooked easily even when the thread comes off, and that a knot can be shifted to a side to be ligated, to enable a surgeon to ligate easily, and to reduce burden on the surgeon and a patient by enhancing workability. SOLUTION: A tip opening 3 and side openings 4 are made at an end of a main part 2 of a ligator. Each end of a thread 50 hooked at a part to be ligated is put through the tip opening 3 and the side opening 4. While the ends of the thread 50 are held with a knot 51 positioned in the tip opening 3, a surgeon operates the main part 2 of the ligator to insert it and ligate. As a result, the surgeon can insert the ligator into a body without happenings that the knot 51 shifts or that the thread 50 comes off and can ligate quickly. As the knot 51 can be moved while having it followed the tip of the main part 2 of the ligator, and an excessive force is not applied to the part to be liageted and the thread 50, safety is increased.

2. Description of the Related Art In surgical operations, reducing the size of an incised portion has been regarded as important in order to speed up post-operative recovery and to reduce the size of the surgical trace remaining on the body. Endoscopy operations that can be performed are being actively performed. In such endoscopic surgery, it is necessary for a practitioner to ligate tissues or blood vessels in the body with a thread or to fix the suture after suturing through a small incision provided in the body, A device called a ligature has been conventionally used to enable such a work of tying a thread in the body from outside the body. An example of such a conventional ligature is disclosed in Japanese Patent Publication No. 6-40880, which is shown in FIGS. 22 and 23. FIG. 22 is a schematic configuration diagram of a conventional ligature, and FIG. 23 is a longitudinal sectional view of a main part of the conventional ligature.

A conventional ligature 100 shown in each of the above figures has a handle 101 having a predetermined length, a recess 102 formed at the tip of the handle 101, and a communication with the recess 102.
And a guide path 103 disposed on both sides of the handle 101 at the tip of the handle 101 from the bottom of the recess 102.
The ligating operation of the conventional ligating device 100 will be described. In advance, use a different device to ligate the body in the body (body tissue,
A thread 50 is hung on a blood vessel or the like, and both ends of the thread 50 are drawn out of the body. First, the practitioner makes a knot 51 on the thread 50 outside the body, hangs the thread at both ends of the knot 51 on the guide path 103 next to the concave portion 102, and holds the end of the thread 50 to push the ligature 100. The thread 50 smoothly slides on the guide path 103 without the concave portion 102 contacting the knot 51,
The knot 51 shifts with the tip of the ligature 100. The ligature 100 is inserted into the body as it is, and the knot 51 is shifted toward the ligature target portion in the body. When the knot 51 is finally pushed down to the ligature target portion, the thread 50 is moved without moving the ligature 100 as it is. The thread 51 is tied by pulling from outside the body, and the ligated portion is set in a ligated state.

In conventional endoscopic surgery, a port (see FIG. 1) is used which is fixed to the surface of a body and facilitates insertion and removal of instruments such as ligatures into the body. When using a sealed port for endoscopic surgery using the pneumoperitoneum method, the port has a built-in valve to prevent gas leakage, and the port is hung over the ligating target site and the end is pulled out of the body. An intermediate portion of the warp yarn 51 is in a bent state in contact with the valve. When the ligature 100 is inserted into such a port, one of the yarns 50 hung on the guide paths 103 at both ends is disengaged by bending of the yarn in the vicinity of the valve, and the knot 51 is displaced from the concave portion 102, so that the slip of the yarn becomes poor. There was a problem that it was easy. Also,
When the ligature 100 pushes and opens the valve and further enters the port, the force for pushing back and closing the valve is applied to the ligature 1.
00 acts as a resistance, but the practitioner
There is a problem that it is difficult to determine whether the resistance has been shifted or the resistance of the repulsive force of the valve, and it may not be possible to correctly determine whether to continue the work.

If the operator continues to insert the ligature 100 without determining the displacement of the knot 51 of the thread 50,
There is a risk that the thread 50 may be cut off in the middle or that the portion to be ligated to which the thread 50 is hung may be excessively applied and damaged. However, when the thread 50 comes off from the distal end of the ligature 100 in the port, the inside of the port may not be visible, and there is a problem that it is extremely difficult to thread the ligature 100 again. On the other hand, in the case of using a closed type port, since the thickness of the conventional ligature 100 is different on the way, a gap is generated in a port large enough to pass through the largest part, and the insufflation gas is not operated. However, there is a problem that it is easy to leak to the outside, and it is difficult to secure a visual field with an endoscope, which may lead to interruption of the operation. The present invention has been made in order to solve the above-mentioned problem, and has a tip shape in which the thread is hard to be detached from the tip and can be easily returned to a hung state even when the thread is detached, and the knot of the thread is securely shifted to the side to be ligated. In addition, an object of the present invention is to provide a ligating device that allows a practitioner to easily perform a ligating operation, significantly improve workability, and reduce the burden on both the practitioner and the practitioner.
