Description

The present invention relates to a phimosis correction device used to correct phimosis, particularly true phimosis.

True phimosis, in which the entire glans is covered by the foreskin and the glans is not exposed at all during erection, can be corrected through plastic surgery to remove the excess foreskin and widen the foreskin ring (foreskin opening). However, there was a problem in that the surgery cost was extremely high, and the post-surgery hospital visit and drug costs also increased, creating a large financial burden.

In addition, during phimosis surgery, the foreskin may be cut too far, resulting in the foreskin becoming taut during an erection, the sutured area of the foreskin becoming ugly, such as a keloid, or a part of the erogenous zone being removed along with the foreskin. It is known that there are risks such as inability to ejaculate due to damage to the erogenous transmitting nerves. After the surgery, the pain continues for about two weeks, and during that time, the phimosis patient is forced to live a life of inconvenience, having difficulty bathing or urinating because the bandage cannot be removed. Furthermore, many patients with phimosis are unable to undergo surgery due to embarrassment and suffer in secret.

According to the ``Children's Phimosis Consultation Room'' (Non-Patent Document 1), true phimosis is caused by a small foreskin ring (foreskin opening) at the tip of the foreskin that envelops the glans, and that ``use forceps to widen the foreskin ring.'' ``The glans can be exposed through the opening of the phimosis,'' and further states that ``it is desired that a phimosis correction tool that can be easily handled by non-specialists be commercially available.''

In addition, ``Don't cut it! The truth about phimosis that Japanese people don't know'' (Non-patent Document 2) points out the usefulness of the foreskin, but denies phimosis surgery, and advocates widening the foreskin ring. We encourage true phimosis correction. The urologist who is the author of Non-Patent Document 2 has a wealth of experience in actually correcting true phimosis by widening the foreskin ring with forceps, and says, ``True phimosis does not require surgery and can be corrected by widening the foreskin ring. "It can be done."

An example of a phimosis correction tool devised to widen the foreskin opening of phimosis is the phimosis correction tool described in Patent Document 1. In the phimosis correction tool of Patent Document 1, when the grip consisting of two handles is grasped against the elastic force of the spring, the two jaws open and the pair of blades provided at right angles to the tips of both jaws touch each other. It is a pliers-like instrument configured to move in the direction of separation. With this phimosis correction tool, by inserting the pair of blades into the foreskin opening of true phimosis and squeezing the grip, the distance between the blades is maintained by the ratchet mechanism, so even if you use it continuously for a long time, your hands will not be able to handle it. You can spread the foreskin opening by effectively applying tension to the extent that you feel some pain without feeling sluggish or tired.

However, pliers-like instruments are not only large and heavy, but when using them yourself, the blades must face you and the grip must be positioned on the other side of the blades, so you must bend your wrists to hold the pliers. It feels like holding it with the other hand, making it extremely difficult to use. Furthermore, since the wrist is turned back, not only is it difficult to operate the ratchet, but the spacing between the blades can only be adjusted in stages, making it impossible to push the foreskin opening as wide as desired. Furthermore, since the blade opens and closes easily by opening and closing the grip, if the ratchet comes off while the foreskin opening is being stretched, or if force is applied in the direction of opening the grip, the blade will close and correct the correction. This results in work being interrupted. Furthermore, pliers-like instruments have complicated shapes of individual parts, which poses a problem in terms of manufacturing costs.

Further, as other types of phimosis correction tools, for example, the phimosis correction tool described in Patent Document 2 is known. In the phimosis correction tool described in Patent Document 2, when a pair of blades is inserted into the foreskin opening of the phimosis and the two legs that serve as a grip are squeezed, the pair of blades move in a direction away from each other. The foreskin opening is configured to be expanded from the inside. Then, when the grip force is released, the pair of blades automatically return toward each other due to the restoring force of the spring, and are in a state where they can be easily pulled out from the foreskin opening. Therefore, this phimosis correction tool can be mass-produced by a simple process of bending the spring material without using expensive molds, so the manufacturing cost is very low, and at the same time, it is lightweight and not bulky, so it can be used in bags. It is convenient to carry it in your bag, clothes pocket, etc.

Japanese Patent Application Publication No. 2004-141188 Japanese Patent Application Publication No. 2003-220084

In the phimosis correction tool of Patent Document 1 mentioned above, the user, specifically, the phimosis patient, inserts the blade into the foreskin opening of the phimosis and grasps the grip, and then applies a certain amount of force to the blade. The spacing can be maintained, thus making it possible to correct phimosis. Similarly, in the phimosis correction tool of Patent Document 2 mentioned above, when the pair of blades is inserted into the foreskin opening of the phimosis and the two legs that serve as the grip are squeezed, the pair of blades move in the direction away from each other. The foreskin opening can be pushed open from the inside. On the other hand, in the type with a stopper, when the foreskin ring is expanded, the foreskin ring expands over time, so the load (tension) to spread the foreskin ring decreases.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a phimosis correction device that can apply a load even if the user removes his/her hand, and can continue to apply a load even if the foreskin ring expands during use.

To achieve the above object, the phimosis correction tool of the present invention includes a first arm and a second arm that are rotatably connected to each other via a fulcrum, and one end of each of the first arm and the second arm. a pair of raised parts that are inserted into the foreskin ring, and a pair of raised parts that are inserted into the foreskin ring; and a pair of raised parts that are inserted into the foreskin ring; The device includes an attached elastic body that biases the pair of raised portions in a direction to separate them from each other.

Embodiments of the present invention will be described below with reference to the drawings. However, the constituent elements described in the following examples are merely examples, and the technical scope of the present invention is not intended to be limited thereto. In addition, in the following, an example in which the elastic body is arranged on the opposite side of the fulcrum to the rising part in Example 1 will be explained, and an example in which the elastic body is arranged in the fulcrum on the same side as the rising part in Embodiment 1 will be explained. .

(composition)
First, the configuration of the phimosis correction tool 1 of Example 1 will be described with reference to FIGS. 1 and 2. The phimosis correction device 1 of Example 1 includes a first arm 21 and a second arm 22 that are rotatably connected to each other via a fulcrum 20, and one end of each of the first arm 21 and the second arm 22 is raised. A pair of raised parts 31, 32 that are inserted into the foreskin ring, and a pair of raised parts 31, 32 about the fulcrum 20 in the first arm 21 and second arm 22, 32, the elastic body 40 is attached to the side opposite to 32, and biases the pair of upright portions 31 and 32 in a direction to separate them from each other.

The first arm 21 is made of synthetic resin or the like, and includes a portion 21A that extends linearly in one direction from the fulcrum 20, which is a rotating shaft, and has a raised portion 31 at the tip, and a portion 21A that extends from the fulcrum 20 while bending. and a portion 21B to which the elastic body 40 is attached. Looking at this with respect to the fulcrum 20, the upright portion 31 and the mounting position 41 of the elastic body 40 are located on opposite sides.

In addition, the first arm 21 further includes a safety stopper 50 for adjusting the maximum opening width of the first arm 21 and the second arm 22. The safety stopper 50 is located near the fulcrum 20 but on the opposite side of the upright portion 31 with respect to the fulcrum 20. The safety stopper 50 includes a screw shaft 51 that moves forward and backward relative to the first arm 21, and a handle 52 for manually rotating the screw shaft 51. The amount of protrusion is adjusted by rotating the handle 52 in the forward/reverse direction, so that the tip of the protruding screw shaft 51 comes into contact with the abutting wall 221 of the second arm 22. The function of this safety stopper 50 will be described later with reference to FIG.

A rising portion 31 is provided at one end of the first arm 21 in a direction perpendicular to the first arm 21 . The rising portion 31 includes a cylindrical straight portion 311 that stands up substantially perpendicularly from the tip of the first arm 21, and a hemispherical portion 312 formed at the tip of this straight portion 311.

Similarly, the second arm 22 is made of synthetic resin or the like, and includes a portion 22A that extends linearly in one direction from the fulcrum 20, which is the rotation axis, and has a raised portion 32 at the tip, and It consists of a portion 22B that extends while being bent at a substantially right angle and to which the elastic body 40 is attached. Looking at this with respect to the fulcrum 20, the upright portion 31 and the mounting position 42 of the elastic body 40 are located on opposite sides.

A raised portion 32 is provided at one end of the second arm 22 and raised in a direction perpendicular to the second arm 22 . The rising portion 32 includes a cylindrical straight portion 321 raised substantially perpendicularly from the tip of the second arm 22, and a hemispherical portion 322 formed at the tip of the straight portion 321.

The elastic body 40 of this embodiment is a spring (histral spring; tension spring) that applies a tensile force during use, and is attached to the opposite side of the fulcrum 20 from the pair of upright portions 31 and 32.

That is, since the elastic body 40 is attached in a state where it is stretched (pulled) more than its natural length, it acts to draw the attachment positions 41 and 42 toward each other. Therefore, the pair of upright portions 31 and 32 located on the opposite sides of the mounting positions 41 and 42 with respect to the fulcrum 20 are urged in the direction away from each other.

The elastic body 40 of this embodiment is provided with a tension adjustment mechanism (43-45) for adjusting the tension generated by the elastic body 40 (force that separates the raised portions 31 and 32; force that pulls the foreskin). Further provided. Specifically, the tension adjustment mechanism includes a gear pin 43 that interlocks with the mounting position 42, a gear shaft 44 for slidingly driving the gear pin 43, and a handle 45 for manually rotating the gear shaft 44. It consists of Then, by rotating the handle 45 in the forward/reverse direction, the gear shaft 44 is rotated, and the gear pin 43 is moved along the gear shaft 44. Then, the attachment position 42 on the second arm 22 side will move, and the distance from the attachment position 41 on the first arm 21 side will change, and the distance to the fulcrum 20 will also change. The operation of this tension adjustment mechanism (43-45) will be described later with reference to FIG.

(effect)
Next, the function of the phimosis correction tool 1 will be explained using FIGS. 3 to 5.

When adjusting the maximum opening width, as shown in FIGS. 3(a) and 3(b), turn the handle 52 of the safety stopper 50 in the forward direction to narrow it, or in the opposite direction to widen it. and can be adjusted.

That is, in order to narrow the maximum opening width, as shown in FIG. , the tip of the screw shaft 51 is brought into contact with the abutment wall 221.

On the other hand, to widen the maximum opening width, turn the handle 52 in the opposite direction to reduce the amount of protrusion of the screw shaft 51, so that the opening angle of the first arm 21 is large, as shown in FIG. 3(b). The tip of the screw shaft 51 is brought into contact with the abutment wall 221.

When adjusting the elastic force with the tension adjustment mechanism, as shown in FIGS. 4(a) and 4(b), turn the handle 45 of the tension adjustment mechanism (43-45) in the positive direction to increase the tension, You can adjust it by turning it in the opposite direction to weaken the tension.

That is, to increase the tension, as shown in FIG. 4(a), rotate the handle 45 in the opposite direction to move the gear pin 43 to the left in the figure, and move the mounting position 42 of the elastic body 40 away from the fulcrum 20. Let go. In this case, the length of the arm of the moment becomes longer, and the force that pulls apart the rising parts 31 and 32 on the opposite side becomes larger.

On the other hand, to weaken the tension, turn the handle 45 in the positive direction to move the gear pin 43 to the right in the figure, as shown in FIG. get closer to Then, since the length of the moment arm becomes shorter, the force that pulls the opposite rising parts 31 and 32 apart becomes smaller.

Next, a method of using the phimosis correction tool 1 of this embodiment will be explained using FIGS. 5(a) and 5(b). The method for using the phimosis correction tool 1 includes at least the following three steps 1) to 3).
1) Step of grasping the arms 21 and 22 with hands to reduce the distance between the upright portions 31 and 32. That is, grasping the force points of the arms 21 and 22. Then, the hemispherical portions 312 and 322 of the rising portions 31 and 32 approach each other.
2) Step of inserting the raised portions 31 and 32 with a reduced interval into the foreskin ring from the front (FIG. 5(a))
That is, the hemispherical portions 312, 322 at the tip of the instrument are slowly inserted into the preputial ring.
3) The step of releasing the hands holding the arms 21 and 22 and applying outward tension to the foreskin ring (Fig. 5(b))
That is, by loosening the grip force, the foreskin ring is expanded by the repulsive force of the elastic body 40. By repeating this method of use over a predetermined period of time, the foreskin ring gradually expands and true phimosis is cured.

(effect)
Next, the effects of the phimosis correction tool 1 of Example 1 will be listed and explained.
(1) As described above, the phimosis correction tool 1 of this embodiment includes a first arm 21 and a second arm 22 that are rotatably connected to each other via a fulcrum 20, and a first arm 21 and a second arm that are rotatably connected to each other via a fulcrum 20. A pair of upright parts 31 and 32 with one end of each of the foreskin rings 22 upright, and a pair of upright parts 31 and 32 that are inserted into the foreskin ring, and a fulcrum in the first arm 21 and the second arm 22. 20 is provided with an elastic body 40 attached to the opposite side of the pair of rising parts 31 and 32, and biasing the pair of rising parts 31 and 32 in a direction to separate them from each other. With these configurations, the elastic body 40 can always bias the upright portions 31 and 32 at one end in the direction of expanding, so a load can be applied even when the hands are removed, and the load can be applied during use. The phimosis correction tool 1 can continue to apply a load even if the foreskin ring widens.

(2) Furthermore, since the safety stopper 50 for adjusting the maximum opening width of the first arm 21 and the second arm 22 is further provided, it is possible to prevent damage to the foreskin due to the arms 21 and 22 opening too much. In other words, it prevents your hand from slipping and causing the tip to spread out unexpectedly, thereby preventing sudden stress from being placed on the foreskin ring. Furthermore, by gradually increasing the maximum opening width during the period of use, the foreskin ring can be gradually stretched and phimosis can be cured.

(3) In addition, if it further includes a tension adjustment mechanism (43-45) for adjusting the tension generated by the elastic body 40 (force to separate the rising parts 31 and 32; force to pull the foreskin), Too much tension can prevent damage to the foreskin. In particular, if the phimosis correction tool 1 is equipped with the safety stopper 50, the tension will change when adjusting the maximum opening width, so the need for the tension adjustment mechanism (43-45) becomes even greater.

(4) Moreover, the tension adjustment mechanism (43-45) adjusts the attachment position 41, 42 of the elastic body 40 to the first arm 21 or the second arm 22 to change the distance from the fulcrum 20. Therefore, the applied tension can be increased or decreased steplessly by a simple operation without replacing the elastic body 40. By providing the tension adjustment mechanism in this manner, it is possible to flexibly respond to tensions that vary depending on the hardness and extent of the foreskin ring.

(5) Furthermore, the method of using the phimosis correction device of this embodiment is a method of using any of the phimosis correction devices 1 described above,
1) a step of grasping the first arm 21 and the second arm 22 by hand to reduce the distance between the rising parts 31 and 32;
2) a step of inserting the raised portions 31 and 32 with a reduced interval into the foreskin ring;
3) releasing the hands grasping the first arm 21 and the second arm 22 to apply an outward tension to the preputial ring. How to use the phimosis correction device 1 in this way allows you to apply a load even if you remove your hand, and to continue applying the load even if the foreskin ring expands during use. becomes.

Hereinafter, a phimosis correction tool 1A having a different form from the first embodiment will be described using FIGS. 6 to 9. Note that parts that are the same as or equivalent to those described in the first embodiment will be described using the same reference numerals.

(composition)
Next, the configuration of the phimosis correction tool 1A of Example 2 will be described with reference to FIGS. 6 and 7. The phimosis correction tool 1A of the second embodiment includes a first arm 21 and a second arm 22 that are rotatably connected to each other via a fulcrum 20, and one end of each of the first arm 21 and the second arm 22 is raised. A pair of raised parts 31, 32 that are inserted into the foreskin ring, and a pair of raised parts 31, 32 about the fulcrum 20 in the first arm 21 and second arm 22, The elastic body 40 is attached to the same side as 32 and biases the pair of rising parts 31 and 32 in a direction to separate them from each other.

The first arm 21 is made of synthetic resin or the like, and extends linearly in one direction from the fulcrum 20, which is a rotating shaft, and has a raised portion 31 at its tip and an elastic body 40 at its base end. It is composed of a portion 21A that is attached and a portion 21B that is bent at a substantially right angle from the fulcrum 20. In addition, the first arm 21 further includes a safety stopper 50 for adjusting the maximum opening width of the first arm 21 and the second arm 22. The configuration of the safety stopper 50 is substantially the same as that in the first embodiment, so a description thereof will be omitted.

A rising portion 31 is provided at one end of the first arm 21 in a direction perpendicular to the first arm 21 . The rising portion 31 includes a cylindrical straight portion 311 that stands up substantially perpendicularly from the tip of the first arm 21, and a hemispherical portion 312 formed at the tip of this straight portion 311.

Similarly, the second arm 22 is formed of synthetic resin or the like, extends linearly in one direction from the fulcrum 20 that is the rotation axis, has a raised portion 32 at the tip, and has an elastic member at the base end. It is composed of a portion 22A to which the body 40 is attached, and a portion 22B bent at a substantially right angle from the fulcrum 20.

A raised portion 32 is provided at one end of the second arm 22 and raised in a direction perpendicular to the second arm 22 . The rising portion 32 includes a cylindrical straight portion 321 raised substantially perpendicularly from the tip of the second arm 22, and a hemispherical portion 322 formed at the tip of the straight portion 321.

The elastic body 40 of this embodiment is a spring (histral spring; tension spring) that applies a tensile force during use, and is attached to the same side of the fulcrum 20 as the pair of upright portions 31 and 32. That is, since the elastic body 40 is attached in a state shortened (compressed) from its natural length, it acts in a direction to separate the attachment positions 41 and 42 from each other. Therefore, the pair of upright portions 31 and 32 located on the same side of the fulcrum 20 as the mounting positions 41 and 42 are urged away from each other.

The elastic body 40 of this embodiment is further provided with a tension adjustment mechanism (43-45) for adjusting the elastic force of the elastic body 40. Specifically, the tension adjustment mechanism includes a gear pin 43 that interlocks with the mounting position 42, a gear shaft 44 for slidingly driving the gear pin 43, and a handle 45 for manually rotating the gear shaft 44. It consists of Then, by rotating the handle 45 in the forward/reverse direction, the gear shaft 44 is rotated, and the gear pin 43 is moved along the gear shaft 44. Then, the attachment position 42 on the second arm 22 side will move, and the distance from the attachment position 41 on the first arm 21 side will change, and the distance to the fulcrum 20 will also change. The operation of this tension adjustment mechanism (43-45) will be described later with reference to FIG.

(effect)
Next, the operation of the phimosis correction tool 1A will be explained using FIGS. 8 and 9.

When adjusting the elastic force using the tension adjustment mechanism, as shown in FIGS. 8(a) and 8(b), turn the handle 45 of the tension adjustment mechanism (43-45) in the positive direction (counterclockwise) to adjust the tension. You can adjust the tension by increasing the tension, or by turning it in the opposite direction (clockwise) to weaken the tension.

That is, to increase the tension, as shown in FIG. 8(a), turn the handle 45 counterclockwise to move the gear pin 43 upward in the figure, and move the mounting position 42 of the elastic body 40 to the fulcrum 20. away from. In this case, the length of the arm of the moment becomes longer, and the force that separates the rising parts 31 and 32 from each other becomes larger.

On the other hand, to weaken the tension, turn the handle 45 clockwise to move the gear pin 43 downward in the figure, as shown in FIG. get closer to In this case, the length of the arm of the moment becomes shorter, so that the force that separates the upright portions 31 and 32 from each other becomes smaller.

Next, a method of using the phimosis correction tool 1 of this embodiment will be explained using FIGS. 9(a) and 9(b). The method of using the phimosis correction tool 1A of this embodiment includes at least the following three steps 1) to 3).
1) A step of grasping the arms 21 and 22 by hand to reduce the distance between the upright portions 31 and 32. That is, grasping the force points of the arms 21 and 22. Then, the hemispherical portions 312 and 322 of the rising portions 31 and 32 approach each other.
2) Step of inserting the raised parts 31 and 32 with a reduced interval into the foreskin ring from the front (FIG. 9(a))
That is, the hemispherical portions 312, 322 at the tip of the instrument are slowly inserted into the preputial ring.
3) The step of releasing the hands holding the arms 21 and 22 and applying outward tension to the foreskin ring (Fig. 9(b))
That is, by loosening the grip force, the foreskin ring is expanded by the repulsive force of the elastic body 40. By repeating this method of use over a predetermined period of time, the foreskin ring gradually expands and true phimosis is cured.

(effect)
Next, the effects of the phimosis correction tool 1A of Example 2 will be explained.

As described above, the phimosis correction tool 1A of this embodiment includes the first arm 21 and the second arm 22, which are rotatably connected to each other via the fulcrum 20, and the first arm 21 and the second arm 22, respectively. A pair of raised parts 31, 32 with one end raised up, which are inserted into the foreskin ring, and a pair of raised parts 31, 32 with one end raised up, and a pair of raised parts 31, 32 with one end raised up, and a pair of raised parts 31, 32 with one end raised up, and a pair of raised parts 31, 32 with one end raised up, and a pair of raised parts 31, 32 with one end raised up, and a pair of raised parts 31, 32 with one end raised up, which are inserted into the preputial ring. The elastic body 40 is attached to the same side as the rising parts 31 and 32, and biases the pair of rising parts 31 and 32 in the direction of separating them from each other. With these configurations, the elastic body 40 can always bias the upright portions 31 and 32 at one end in the direction of expanding, so a load can be applied even when the hand is removed, and the load can be applied even during use. The phimosis correction tool 1 can continue to apply a load even if the foreskin ring widens.

Furthermore, compared to the phimosis correction tool 1 of Example 1, the overall size can be made more compact. In other words, the overall size can be reduced by reversing the positions of the fulcrum and the point of effort and arranging the points of effort (attachment positions 41, 42) on the distal end sides of the arms 21, 22.

Note that the other configurations and effects are substantially the same as those in the first embodiment, and therefore description thereof will be omitted.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention may be made to the present invention. included.
