Abstract

PURPOSE:To enable an annular pessary for treating the prolapse of the uterus to be inserted into the genitalia while being bent and reduced in transverse outside diameter and to facilitate insertion of the pessary by providing the pessary with bending means by which the pessary can be recoverably bent. CONSTITUTION:A pessary 1 comprises two semicircular arcs 2 connected together in such a manner as to be bendable using bending means 10 (10A, 10B). Each of the arcs 2 is made from a synthetic resin with appropriate rigidity or metal, and each of the bending means 10 is formed by interlocking stepped levels provided at both end portions 3 of each of the arcs 2 and by pivotally supporting the interlocked portion by means of a stopping shaft 7. One of the bending means 10A is provided with a control lever 11 for locking the pessary 1 in an expanded (circular) state, and the control lever 11 rolls around the shaft 14 under energizing of a spring 19 and a locking portion 12 provided at the end of the lever is engaged in a locking groove so that the lever is locked.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved pessary for uterine prolapse therapy.

[0002]

2. Description of the Related Art Conventionally, a ring-shaped pessary has been used for conservative therapy (treatment without surgery) for uterine prolapse disease in elderly women. Pessaries are available in several sizes, and the ones that match the size are used.

[0003]

However, there is a problem that the pessary is very difficult to insert when inserting it into the vagina from the vulva of the therapist. In other words, because the vaginal diameter is larger than the vulva, a pessary slightly larger than the vulva must be used, and because the vulva is anatomically long, it is necessary to use it when inserting it. It will be painful. Therefore, an object of the present invention is to solve the above-mentioned inconvenient problems in conventional pessaries, and to provide a pessary for uterine prolapse therapy which is easy to insert and can sufficiently exhibit its function after insertion. To do.

[0004]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the means of the present invention is an annular pessary for uterine prolapse treatment, and the folding means is capable of being restored to the annular shape. Is provided.

[0005]

[Function] When inserting the pessary into the vulva, bend it to reduce the outer diameter width. The folded pessary is convenient for vulva passage. After insertion in the vagina, the bent pessary is returned to the prescribed annular shape. The ring-shaped pessary presses the uterus in the vagina.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the pessary 1 of this example has an annular shape, and the bending means 10 is provided at two diametrical positions.
It is formed to be bendable via A and 10B. That is, the two semicircular arcuate bodies 2 for forming the pessary 1 are made of synthetic resin (or metal in some cases) having an appropriate rigidity and having a substantially circular cross section as shown in FIG. Each end 3 is formed in a stepped shape as shown in FIG.
In addition, the end face 4 is formed into a curved surface (see the shape of the end face 4 in FIGS. 2 and 3) centered around the stop shaft 7, and as shown in FIG. Bending means 10A and 10B are formed by inserting the shaft 7. The one bending means 10A is provided with an operation lever 11 for locking and unlocking the bending of the pessary 1, that is, the bending of the one stop shaft 7 of the arcuate body 2.

The operating lever 11 and its related parts are
It has the structure shown in FIGS. The end surface (curved surface) 4 of the one arcuate body 2 in the bending means 10A portion is engaged with a locking portion 12 of the operation lever 11 which will be described later.
As shown in FIG. 6, the curved shape is processed and the engaging groove 5 and the locking projection 6 are provided. A mounting recess 16 for the operating lever 11 is provided on the side of the stop shaft 7 of the other arcuate body 2 related to the bending means 10A. As shown in FIGS. 5 and 6, the mounting recess 16 is provided with an insertion recess 17 for the locking projection 6 on the stop shaft 7 side, and a slanting deep groove 18 on the rear side.
A part of the deep groove 18 is a recessed spring seat 18A. The operating lever 11 has a hook-shaped engaging portion 12 which can be engaged with and disengaged from the engaging groove 5, and a concave spring seat 11A is provided inside the rear portion.

As shown in FIG. 5, the operating lever 11 is housed in the mounting recess 16, and a spring 19 for urging the operating portion 13 at the rear of the operating lever 11 outward is interposed between the spring seats 11A and 18A. Is mounted, and in the state where the locking portion 12 is engageable with the locking groove 5, it is axially supported by the stop shaft 14 at the outer portion of the mounting recess 16 in the central portion. As shown in FIG. 5, the operating lever 11 is in the normal state when the locking portion 12 is engaged with the locking groove 5, and the pessary 1 at this time has the normal shape shown in FIG. As shown in FIG. 6, the operating portion 13 of the operating lever 11 is pushed against the biasing force of the spring 19 to release the locking portion 12 from the locking groove 5 (unlocking (locking portion 12 of phantom line in FIG. 5 2), it is possible to bend both arcuate bodies 2 around the stop shaft 7 to a position where the locking portion 12 contacts the locking projection 6 (FIGS. 8 and 7).
See the shape). The pessary 1 bent into the shape shown in FIG.
In order to restore the normal shape, the both arcuate bodies 2 should be bent back so as to have the circular shape shown in FIG. 1, and the operating lever 11 is automatically urged by the spring 19 from the state shown in FIG. The regular shape of FIG. 5 can be obtained.

Therefore, when using the (regularly shaped) pessary 1 of this example, after pushing the operating portion 13 of the operating lever 11 and bending both arcuate bodies 2 to narrow the width of the pessary 1 (FIG. 7). , See the shape of FIG. 8), as usual, it can be inserted into the vagina from the vulva of the therapist, restored to the normal shape in the vagina, and placed in the uterine portion to be used for treatment of uterine prolapse. Since the pessary 1 of this example has a narrow width and passes through the vulva, it is easy to insert. In addition, after passing the vulva, the pessary 1 can be easily restored to the normal shape in the vagina, and the uterus is supported by the pessary 1 having the normal shape. Therefore, the original function of the pessary 1 is the same as the conventional one. You can do it. The pessary 1 having a regular shape does not bend during treatment because the bending means 10A is locked by the lock of the operation lever 11. When the pessary 1 used to support the uterus is removed from the vagina, the operation portion 13 of the operation lever 11 is pushed by an appropriate means to unlock the bending means 10A, and the pessary 1 is pushed and bent to be in a narrow state. Pass through the vulva.

The folding means 10A of the pessary 1 which is locked and unlocked by the operation of the operating lever 11 is not limited to the structure of this example, and a wide range of structures that can be folded in a recoverable manner is widely used. Can be adopted.

[0011]

EFFECTS OF THE INVENTION The present invention is a pessary provided with a folding means, which can be inserted into the vulva in a state where it is folded to reduce the outer diameter width in the lateral direction. It can be inserted, restored to its original annular shape in the vagina, and pressed against the uterus to treat uterine prolapse.
