Abstract

PURPOSE:To simply change over the closure and opening of a body lumen by using a body lumen insert jig consisting of an insert jig main body formed into a tubular shape and a plurality of the plug jigs inserted and held in the insert jig main body in a freely detachable manner. CONSTITUTION:A hole 4 having an almost square shape is bored in the side surface part of one end of an insert jig main body 2 and plug jigs 3 having an almost spherical shape are inserted in the insert jig main body 2. At the time of sterility, incision having a length capable of inserting the insert jig main body is applied to the seminal canal A and the insert jig main body 2 in which a plurality of the plug jigs 3 are preliminarily inserted is inserted in the seminal canal A. Since the seminal canal A is closed by the plug jigs 3 inserted in the insert jig main body 2 in this state, the movement of the supermatozoa in the seminal canal A is blocked to obtain contraceptive effect. When generative function is desired to be returned if necessary, only the part of the hole 4 of the insert jig main body 2 of the seminal canal A is incided to take out the plug jigs 3. whereupon, the supermatozoa can pass, through the insert jig body 2 and generative function can be restored.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an insert to be inserted into a body canal during sterilization surgery, and more specifically to an insert that reversibly controls the movement of sperm in the vas deferens or eggs in the fallopian tubes. The present invention relates to an intracorporeal endotube device used for isolating blood vessels.

(Prior Art) Conventionally, there are body canal insertion tools used in these sterilization operations, which have the shapes shown in the third factors (a) to (c).

These conventional devices consist of a single insert, and the insert is directly inserted into the body canal and held tightly against the inner wall of the body canal to close the body canal. It is removed from the body canal and the body canal is opened again.

(Problems to be Solved by the Invention) However, since these conventional intrabody catheters have a single insert, the entire insert must be taken in and out each time the body canal is closed or opened. In other words, even in the case of restoration surgery to restore the reproductive function once the reproductive function has been stopped, the work required is the same as or more than that required for the sterilization surgery.

Furthermore, the above-mentioned occlusion in the body canal is maintained by the close contact between the inner wall of the body canal and the surface of the insert, and for example, there is a risk that the tissue of the inner wall of the body can become integrated with the surface of the insert due to changes over time after inserting the insert. In this case, there were problems such as peeling off the inner wall of the body canal when removing the insert from inside the nuclear body canal.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an intrabody canal insertion tool that can easily switch between closing and opening a body canal.

(Means for Solving the Problems) The present invention solves the above problem by providing an insert to be inserted into a body canal with a tube-shaped insert main body and a tool fitted into the insert main body as separate structures. This was done in an attempt to resolve the issue.

That is, the present invention provides an insert main body 2 formed in a tube shape.
This is an intracorporeal endotubal insertion device consisting of a body 2 and a plurality of tools 3 that are removably fitted and held in the insertion device main body 2.

(Function) When performing sterilization surgery using the intracorporeal insertion device configured as described above, first, the body canal is pulled out through an incision at a predetermined cylindrical location, and then the intracorporeal insertion device is inserted into the body canal. Make an incision.

Then, by inserting the body canal endotube, which has a tool fitted into the body of the body in advance, into the body canal through the incision, the body of the body is housed in the body canal, and in this state, the body canal is inserted into the body canal through the incision. The incision in the canal is sutured.

At this time, the body canal is obstructed by the tool inserted into the insertion tool main body, so that moving objects within the body canal are blocked and the sterilization effect can be achieved.

After that, return the pulled out body tube to its original position,
Once the predetermined locations are sutured, the sterilization surgery is completed.

Furthermore, when re-opening the body canal, the body canal is opened by removing only the tool fitted into the body canal while leaving the body canal in the body canal. It is possible to make it into a state. Therefore, once the insert main body is inserted, the sterilization effect can be easily switched.

In addition, since the tool is taken in and out of the tool body,
There is no direct contact with the inner wall of the body canal.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1(a) and 1(b), 1 indicates a body canal insertion device.

Reference numeral 2 indicates a tube-shaped insert main body, and a substantially rectangular hole 4 is bored in one end side surface of the insert main body 2.

Reference numeral 3 indicates a substantially rectangular-shaped fixture inserted into the fixture main body 2.

Figure 4 shows the male reproductive organs: A shows the vas deferens, B shows the scrotum, C shows the testicles, D shows the blood vessels and nerves inside the sex cord, and E shows the penis.

The embodiment of the present invention has the above-mentioned configuration, and the method of use thereof will be explained next. First, in preparation for sterilization surgery, the scrotum B is incised and the vas deferens A is pulled out, and then the vas deferens A is pulled out. As shown, an incision is made with a length that allows insertion of the insert main body 2 into the vas deferens A. Next, the insert main body 2, in which a plurality of tools 3 are fitted in advance, is inserted into the vas deferens A through the incision. do.

After that, as shown in FIG. 2(b), by suturing the incision of the tubular tube A, the main body 2 of the catheter is housed and held within the vas deferens A, and the main body 2 of the main catheter 2 is further secured with the string 5. By wrapping and shielding the body tube in which the catheter is housed, the insert main body 2 can be held securely.

In this state, the vas deferens A is occluded by the tool 3 fitted into the insert main body 2, so the movement of sperm within the vas deferens A is blocked, resulting in a sterile effect.

Then, return the vas deferens Afi pulled out above into the scrotum B,
That shade! Once the IB incision is sutured, the sterilization surgery is complete.

In addition, if you wish to restore the reproductive function as necessary, incise only the part where the hole 4 of the insertion device main body 2 of the vas deferens A is located, as shown in Figure 2 (c), and remove the insertion device. If the spermatozoon 3 is removed from the hole 4, the sperm can pass through the insert main body 2, so that the reproductive function can be restored.

In other words, once the insert main body 2 is housed in the body canal, the contraceptive effect can be easily switched by taking out and inserting only the insert 3.

In this way, the intracorporeal insertion device of the present invention can perform the work related to switching the reproductive function by inserting the tool 3 into the insertion device main body 2,
Since the extraction is performed by extraction, the tool 3 that is actually put in and taken out does not come into direct contact with the inner wall of the vas deferens A, and unlike conventional methods, the insertion tool can be removed by making close contact between the insert and the inner wall of the body canal. There is no possibility of detachment of tissue from the inner wall of the body canal.

In the above embodiment, the intracorporeal insertion device is used for the vas deferens in the male genital organ, but the present invention is not limited thereto, and can be similarly applied to, for example, the fallopian tube in the female reproductive organ.

Also, since the insert main body 2 of the above embodiment has a hole 4, the tool 3 can be taken in and taken out from the hole 4, but this is not a condition and the insert can be taken in and taken out from the end face of the insert main body 2. You may do so. Further, the shape, number, position, etc. of the holes 4 are not critical.

In the above embodiment, the tool 3 has a substantially spherical shape, but the tool 3 is not limited to this, and may have a cylindrical shape, for example, and its material may be selected to avoid contact with the body canal. The material is not limited in any way, and may be made of cotton, silicone, Teflon, synthetic resin, or the like.

Furthermore, in the above embodiments, the string 5 is used to hold the insert main body 2, but this is not a condition and the string 5 does not have to be provided. is not limited to the above.

Other matters The specific structure of the invention is not limited to the above, and the design can be changed within the intended scope of the invention.

(Effects of the Invention) As described above, the present invention allows the body canal to be closed or opened while the main body of the catheter remains inserted into the body canal. After being housed in the body canal, the surgery for this switching can be performed quite simply, which is a very special effect.

In addition, during this reproductive function switching surgery, the surgical tool that substantially closes the inside of the body canal does not come into direct contact with the inner wall of the body canal and does not come into close contact with the inner wall of the body canal, so tissue, etc. inside the body canal must be peeled off. It also has the great advantage of not having to be put away.
