Description

[Detailed Description of the Invention] The present invention relates to an indwelling clip that functions to stop bleeding within a body cavity and to indicate the location of an affected area.

When bleeding in the stomach or intestines is stopped without surgery, the bleeding is stopped by wrapping the bleeding blood vessel with surrounding meat or pinching the opening of the blood vessel. However, there are cases where there is no way to do this, and there are cases where it is desired to place a mark near the affected area to make it easier to see the affected area found with a body cavity scope during the next examination or surgery.

Therefore, the present invention satisfies the above requirements.
Attach a bifurcated claw (multiple prongs) to the tip of the operating wire in a removable manner, pinch the affected area with the claw, remove the claw from the operating wire, and place the nail on the affected area to stop the bleeding. The purpose is to obtain an indwelling clip that serves as a mark or the like.

Next, an embodiment of the present invention will be described with reference to the drawings.The tip is formed into two forks with the tip bent inward, and the claw body is arranged so as not to intersect with each other. ) 1 is made of metal or synthetic resin, a cylindrical body 2 whose rear end is closed with a bottom 2a is positioned behind the claw body 1, and an operating wire 3
pass through the bottom 2a of the cylindrical body 2, and removably attach it to the rear end of the claw body 1, and also removably attach it to the bottom 2a of the cylindrical body 2, thereby attaching the clip part A.
form.

Next, an outer spiral tube 4 whose diameter is larger than that of the cylindrical body 2 is
An inner spiral tube 5 (which does not need to be a flexible tube) having a diameter smaller than that of the cylindrical body 2 is provided inside the tube (which does not need to be a flexible tube). Therefore, the operating wire 3 is inserted through the opening at the tip of the inner spiral tube 5, and as shown in FIG.
The open claw body 1 is placed in the outer spiral tube 4 so as to be closed. In this state, it is inserted into the body cavity through a coelomoscope, etc., and when it reaches the target location, the operating wire 3 is pushed together with the inner spiral tube 5 to cause the claw body 1 to protrude from the outer spiral tube 4, and the claw body 1 is moved to the target location. Apply to a particular place. Then, when the operating wire 3 further pushes out only the inner spiral tube 5, the tip of the inner spiral tube 5 first releases the locking point between the operating wire 3 and the cylindrical body 2, and moves it to the target location. The cylindrical body 2 is closed so as to close the claw body 1 that holds the flesh wall B of the
covers the nail body 1 (Fig. 3). Then, when the inner spiral tube 5 is further pushed, the lock between the claw body 1 and the operating wire 3 is released (Fig. 4), and the claw body 1 is held against the flesh wall B with the claw body 1 still holding the flesh wall B. Clip part A between claw body 1 and cylinder body 2
(Figure 5).

The operating section that performs the above operations may have any configuration, but to give an example, a movable piece 8 is fitted into a cylindrical body 6 connected to the outer spiral tube 4 via a spring 7 at the rear end. An operating piece 10 is provided on the movable piece 8 via a tube body 9. The inner spiral tube 5 is connected to the operating piece 10, and a spring 11 is installed between the cylindrical body 6 and the operating piece 10.

In the drawing, reference numeral 12 is an elongated hole having an allowable movement width of the operating wire 3, 13 is a lever for operating the operating piece 10, and 14 is a moving elongated hole.

Next, to describe its operation, the operating wire 3 is inserted into the inner spiral tube 5 as described above, and the rear end of the operating wire 3 passes through the operating piece 10 and the movable piece 8 from the rear end of the cylindrical body 6. It protrudes and is fixed by a screw with a moving piece 8, so that the amount of movement of the operating wire 3 is limited to the width of the elongated hole 12.

Therefore, when the lever 13 is operated, the operating piece 10
moves forward, and the moving piece 8 also moves to the elongated hole 12 by the spring 7.
When the lever 13 is further operated, the moving piece 8 is stopped at the elongated hole 12, but the operating piece 10 moves forward against the spring 11. The inner spiral tube 5 moves forward (in the state shown in Figs. 3 and 4) and acts on the claw body 1 and the cylinder body 2 to remove the operating wire from each locking part and attach the clip part to the flesh wall as described above. It is to be kept in custody. When the lever 13 is released, both pieces 10 and 8 return to their original positions due to the action of the spring 11.

According to the present invention having the above-described structure and function, in order to stop a bleeding site in a body cavity, the bleeding vessel is pinched with the claw body in order to cover it with surrounding flesh.
Also, when an abnormality is found on the wall of a body cavity, it can be placed around it as a landmark, making it easier to locate the affected area during subsequent examinations and surgeries. In addition, when the clip is left in place, the pinched part causes an ejaculation within the clip, and the clip is separated and excreted.
