Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an endoscope insertion aid provided with a plurality of spacers.

[Problems to be solved by conventional techniques and inventions] In recent years,
Endoscopes, which have a long and thin insertion section inserted into a body cavity and can be used to observe and diagnose affected areas within a body cavity without requiring any incisions, and to perform treatment using treatment tools, are becoming widely used. It became.

The above-mentioned endoscopes include flexible endoscopes that have a flexible insertion section and can be inserted through a curved body cavity route from the oral cavity etc. to observe or diagnose affected areas such as body cavity walls, and flexible endoscopes that have a rigid insertion section that can be inserted into the body cavity through a curved body cavity route to observe or diagnose affected areas such as body cavity walls. There are rigid endoscopes that are inserted through a puncture hole directly toward the affected area in front of the puncture hole, or through a straight insertion route such as the urethra.

By the way, when inserting the above-mentioned rigid endoscope into the uterus, an insertion aid called a voltio (1') ortio adapter is required in order to insert the rigid endoscope in close contact with the cervix and maintain airtightness inside the uterus. . The voltio adapter is provided with an endoscope insertion path that connects the cervical os and the outside of the body. It was determined according to the largest outer diameter of the mantle tube.

However, compared to the inner diameter of the insertion path of the voltio adapter,
The inner one with a much thinner outer diameter? 11t Or, when a mantle tube is inserted, the endoscope or mantle tube plays loose within the insertion part and is not correctly guided to the cervical os. In addition, it is difficult to maintain airtightness, and furthermore, the apparent wall thickness of the cervix-side mouth part of the voltioadapter becomes thinner, causing problems in that the cervix may be damaged or shortened.

[Object of the Invention] The present invention has been made in view of the above circumstances, and is capable of reliably guiding endoscopes or mantle tubes having various outer diameters to the cervical os, maintaining airtightness, and The purpose of the present invention is to provide an endoscope insertion aid that does not injure the neck.

[Means and effects for solving the problems] The present invention provides an adapter having an insertion path that closely contacts the uterine cervix and allows an endoscope or a mantle tube to be inserted into the uterus, and an internal FA scope to be used. Alternatively, the adapter may be provided with a plurality of spacers having an inner diameter slightly larger than the outer diameter of the mantle tube, and the adapter may be selected and combined with the endoscope to be used or a spacer whose outer diameter corresponds to the outer diameter of the tube. It has been made possible.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIGS. 1 and 2 relate to the first embodiment, with FIG. 1 being an explanatory diagram showing the configuration of an adapter and a spacer, and FIG. 2 being an explanatory diagram of the tip of the adapter.

In FIG. 1, an endoscope insertion aid 1 is composed of an adapter 2, a spacer 3.4, and a rubber cap 5.

The adapter 2 includes an elongated insertion section 6 that is hollow with an insertion path 10, a cover 7 provided at the front of the insertion section 6, and a connection section 8 provided at the rear.

Near the front end of the insertion section 6, a receiving section 9 for mounting the cover 7 is provided, and in front of the receiving section 9, a large diameter distal end section 1 is provided.
1 are consecutively installed. The front end of the tip 11 forms a smooth convex curved surface from the front end surface to the outer peripheral surface.

The cover 7 has a substantially cylindrical shape with a closing part 12 on one side, and the bone part 9 is fitted into a through hole provided in the closing part 12, and the tip part 11 is provided so as to be slightly exposed. ing. Further, the base portion 12 is provided with a suction pipe 15, which is connected to an aspirator (not shown) via a stop valve (not shown).

The connecting portion 8 has a circumferential groove 13 on the outer periphery near the rear end of the large diameter, a female thread 16 is threaded on the rear end of the inner periphery, and a circumferential groove 14 is provided in front of the internal thread 16. O-ring 14
a is attached.

The spacer 3 is formed from a small-diameter insertion section 17 that is hollowed out by the insertion path 20, and a large-diameter inH+s1B formed at the rear end of this insertion section 17. This attachment/detachment part 18 has a male screw 18 that can be screwed into the female screw 16 from the front end side, an operating part 19, and a groove part 22 to which a rubber cap 21 is attached. Note that the distal end surface of the insertion portion 17 is formed to be flush with the smooth convex curved surface formed on the distal end portion 11 .

The rubber main ship 21 has a substantially cylindrical shape with one end closed, and a hole 25 having an inner diameter slightly smaller than the insertion path 20 is provided in the closed end surface.

The spacer 4 is formed from a small diameter insertion portion 24 having an insertion path 23 with an inner diameter slightly larger than the insertion path 2o, and a large diameter attachment/detachment portion 26 formed at the rear end of this insertion portion 24. There is. This attachment/detachment part 26 is connected to the female thread 1 from the front part.
6 is provided with a groove portion 31 into which a male screw 27, an operating portion 28, and a rubber cap 29 are fitted. The distal end surface of the insertion portion 24 is formed to be flush with the smooth convex curved surface formed on the distal end portion 11.

The rubber cap 29 has a substantially cylindrical shape with one end closed, and a hole 32 having an inner diameter slightly smaller than the insertion opening 23 is provided in the closed end surface.

The rubber cap 5 has a substantially cylindrical shape with one end ms, and a hole 33 with an inner diameter slightly smaller than the insertion opening 10 is provided in the closed end surface, and a hole 33 with an inner diameter slightly smaller than the insertion port 10 is provided in the inner periphery of the other end. A convex portion 34 is provided in a circumferential manner.

By the way, the adapter 2 is designed to suction the air in the cover 7 by opening and closing a stop valve (not shown) provided in the suction tube, and to adsorb it to the cervix 36. After suction, the air in the insertion path 10 is An endoscope or a mantle tube having an outer diameter slightly smaller than the inner diameter can be passed through the hole 33 of the rubber cap 5 attached to the connecting part 8, inserted through the insertion path 10, and guided to the cervical ostium 37. can.

At this time, since the hole 33 of the rubber cap 5 is slightly smaller than the outer diameter of the endoscope or the mantle, airtightness is maintained at the contact surface between the hole 33 and the endoscope or the mantle.

When using an endoscope or a mantle tube having a slightly smaller outer diameter than the above-mentioned endoscope or mantle tube, the spacer 4 is used.

The insertion portion 24 of the spacer 4 is inserted into the insertion path 10 of the adapter 2, and the female thread 16 and the male thread 27 are screwed together. At this time, the convex curved surfaces formed on the distal end of the insertion section 24 and the distal end 11 of the adapter 2 form the same smooth surface, and furthermore, the O-ring 14a provided on the connecting section 8 Airtightness can be maintained between the adapter 2 and the spacer 4.

After configuring as described above, an endoscope or a mantle tube having an outer diameter slightly smaller than the inner diameter of the insertion path 23 is inserted. Since the gap between the outer diameter of the endoscope or mantle tube and the inner diameter of the spacer 4 is small, there is no play of the endoscope or mantle tube within the insertion path 23, and the endoscope or mantle tube can be inserted into the cervical ostium 37. .

At this time, since the hole 32 of the rubber cap 29 is slightly smaller than the outer diameter of the inner im or the outer tube, airtightness is maintained at the contact surface between the hole 32 and the endoscope or the outer tube.

A spacer 3 is used when inserting an endoscope or cannula having a smaller outer diameter than the above-mentioned endoscope or cannula.

The insertion portion 17 of the spacer 3 is inserted into the insertion path 10 of the adapter 2, and the female thread 16 and the male thread 18 are screwed together. At this time, the convex curved surfaces formed on the distal end of the insertion section 17 and the distal end 11 of the adapter 2 form the same smooth surface, and the O-ring 14a provided on the connecting section 8 Airtightness can be maintained between the adapter 2 and the spacer 3.

After configuring as described above, an endoscope or a mantle tube having an outer diameter slightly smaller than the inner diameter of the insertion path 20 is inserted. Since the gap between the outer diameter of the endoscope or mantle tube and the inner diameter of the spacer 3 is small, there is no play of the endoscope or mantle tube within the insertion path 20, and the endoscope or mantle tube can be inserted into the cervical ostium 37. .

At this time, since the hole 25 of the rubber cap 21 is slightly smaller than the outer diameter of the endoscope or foreign tube, airtightness is maintained at the contact surface between the hole 25 and the endoscope or outer tube.

Also, as shown in Figure 2, spacers 3 and 4 are attached to the adapter 2.
When inserted, a smooth convex curved surface is formed at the distal end, and the upper wall thickness is apparently increased, so that the cervix 36 will not be injured.

In this example, it is compatible with endoscopes or mantle tubes having three types of outer diameters, but the number of spacers may be changed depending on the scale of the endoscope or mantle tube used. good.

Furthermore, the airtightness between the adapter and the spacer is maintained by an O-ring, but it may also be done by a plate packing or the like.

Further, in this embodiment, the adapter and the spacer are connected by screwing, but other methods may be used as long as an appropriate compressive force can be applied to the O-ring to maintain airtightness.

[Effects of the Invention] As explained above, according to the present invention, by providing one adapter and a plurality of spacers, it is possible to maintain airtightness even with endoscopes or mantle tubes with different outer diameters, and also to provide a suitable connection to the cervical os. It can be easily guided and has the additional effect of not damaging the cervix.
