Description

Medical sperm collector

Technical Field

The invention relates to a medical sperm collector.

Background

Due to medical research or therapeutic needs, various sperm collectors have been proposed for collecting male sperm. For example, sperm collectors are used due to the following medical necessity: to ascertain the cause of infertility between couples, the collected sperm is used to check the sexual function of the husband, to treat sexual dysfunction, to secure sperm for artificial insemination, etc.

For example, patent document 1 proposes a sperm collecting device in which an inner wall member made of a gel-like synthetic resin (styrene-based thermoplastic elastomer) having a deep concave space therein is provided in a cylindrical container body made of plastic having a desired hardness and thickness, a plurality of small protrusions and a plurality of wrinkled portions are provided on an inner surface of the inner wall member so as to protrude into the concave space, and an outer wall member made of a polyurethane resin is provided so as to cover the periphery of the inner wall member.

The present applicant has proposed a sperm collecting device in which a gel resin core member is accommodated in a container body, in patent documents 1 to 5. However, since the core member made of gel-like resin has the same internal temperature as the ambient temperature, when the ambient temperature is low, particularly when the internal temperature of the core member is lower than the body temperature of the user, for example, 15 to 20 ℃ or higher, the male genitals feel cool when inserted, and the following problems occur: strong discomfort and uncomfortable feeling, reduced use feeling and atrophy of male genitals.

In order to solve such a problem, a method of heating the sperm collecting device, particularly the core member, from the outside using a heater to approximate the body temperature, such as heating by immersing in hot water, heating with an infrared heater or a microwave oven before use, has been carried out at the beginning. However, this heating method has a problem of heat retention, such as overheating to cause a high temperature state, or heat loss in use.

As described above, since the sperm collecting device has a structure in which the core member is fixed in the resin container body having low thermal conductivity, it is not easy to heat the inside of the core member to an appropriate temperature by heating from the outside of the container body. In addition, in such a heating method, there is a case where there is a high possibility that a problem in safety is caused due to the need for heating for a long time or due to an overheated state.

In view of the above, the present applicant has proposed a heating apparatus for a sperm collecting apparatus in which a gel-like resin core member is housed in a plastic container body and sealed with a lid, wherein the core member is heated from the inside to an appropriate temperature in a concentrated manner, thereby safely raising the temperature to a temperature close to the body temperature in a short time and maintaining a good feeling of use at all times (see patent document 6).

The heating device comprises a base seat having a convex heating member protruding upward from a heating device body accommodating an electric heating unit as a heating mechanism, and capable of standing on a plane; an inner shell having a flange portion around a lower portion of a cylindrical convex portion into which the convex heating member of the base seat is inserted and covered; and an outer shell fitted to and concealing the cylindrical projecting portion of the inner shell, and having a lower end portion fitted to the flange portion of the inner shell. Then, when the heating device is used, a plug arranged on a power line of the electric heating unit is inserted into a power socket, the outer shell is taken down from the base seat, and the exposed cylindrical convex part of the inner shell is inserted into the insertion opening of the core part of the sperm collector. Then, the convex heating member of the base is inserted into the opening on the bottom surface side of the inner shell in the state of being attached to the sperm collecting instrument, and the tip surface of the core member is brought into close contact with the flange portion. Then, the switch is turned on to start warming by the electric heating unit. After the heating is started, after a predetermined time has elapsed, the sperm collector is removed from the inner shell, and the inner shell is removed with the insertion port of the sperm collector facing upward. The sperm collecting device is set in a usable state after the finger is inserted into the insertion port from which the inner shell is taken out and the internal temperature is confirmed to be a proper temperature.

However, since the conventional warmer is a device independent of the sperm collecting device, the first is that time and effort are required to manage the warmer and the sperm collecting device separately. Secondly, because the warmer comprises the base seat, the inner shell and the outer shell, the number of parts is large, and the manufacturing cost is high. Thirdly, since the electric heating unit is used as a warming mechanism, it takes time and labor to insert a plug provided on a power cord into an electric outlet when in use, and the place of use is limited. Fourthly, when the sperm collector is used, the heating can be started through the following multi-step operations, namely, the cover of the sperm collector is taken down, the outer shell of the warmer is taken down from the base platform, the cylindrical convex part of the inner shell is inserted into the insertion opening of the core part of the sperm collector, the convex heating part of the base platform is inserted into the opening of the bottom surface side of the inner shell, and then the switch is opened, so the preparation steps are more, complicated and time-consuming.

[ first embodiment ]

As shown in fig. 1 and 2, a medical sperm collecting apparatus T according to a first embodiment of the present invention includes a main body 10 and a warmer 20 integrally combined with the main body 10. The main body 10 has a case portion 11 shown in the upper part of fig. 1, an outer layer portion 12 provided inside the case portion 11, and an inner layer portion 13 provided inside the outer layer portion 12. The shell portion 11 is formed of a thin hard synthetic resin and formed in a deep cup shape. The outer layer portion 12 is provided inside the case portion 11, and is formed of a thick cup-shaped air-permeable and flexible heat insulating material such as urethane foam. The inner portion 13 is provided inside the outer portion 12, is formed into a bottomed cylindrical shape from a material having super flexibility, for example, an elastic body, and is provided with an inner wall 13a having soft wrinkles at a central position of the inner portion 13. The inner wall 13a forms an elongated insertion hole 13 b. Normally, at least the inlet of the insertion hole 13b and the outer peripheral surface thereof are coated with a lubricating liquid or the like.

The warmer 20 includes a lid 21 and a heating unit 22 provided inside the lid 21. The lid 21 is substantially cylindrical and has an outer peripheral wall 21a and an inner peripheral wall 21b provided inside the outer peripheral wall 21 a. The outer peripheral wall 21a is slightly extended upward from the upper end of the inner peripheral wall 21b, and the extended end thereof is elastically fitted to the lower end outer periphery of the housing portion 11 of the body 10. According to this configuration, the warmer 20 can be attached to and detached from the main body 10.

The lid 21 has a housing space 21c surrounded by the inner peripheral wall 21b and opened downward, and the housing space 21c is provided with a heating means 22. The heating unit 22 includes a tubular member 23 extending upward from the center, a heat generating agent 24 accommodated inside the tubular member 23, and a heat generation starting device 25 disposed below the tubular member 23. The cylindrical member 23 extends from the inner peripheral wall 21b toward one direction along the central axis of the cover portion 21, and is inserted into the insertion hole 13b when the cover portion 21 is mounted on the main body 10. The heat generating agent 24 is accommodated in the tubular member 23, and generates heat when water is supplied thereto. The heat generation starting device 25 is accommodated in the accommodation space 21c, and the heat generation starting device 25 can be operated from the outside of the cover portion 21. In doing so, the heat generating agent 24 starts a hydration reaction.

The tubular member 23 integrally includes a base portion 23a, an intermediate portion 23b, and an insertion portion 23c, wherein the base portion 23a is formed in a cylindrical shape extending upward from an upper inner peripheral surface of the inner peripheral wall 21b, the intermediate portion 23b extends upward from an upper end portion of the base portion 23a to a height substantially equal to that of an upper end portion of the lid portion 21 and is formed in a cylindrical shape slightly thinner than the base portion 23a, and the insertion portion 23c is formed in a cylindrical shape extending upward from an upper end portion of the intermediate portion 23b and is formed in a cylindrical shape slightly thinner than the intermediate portion 23 b. The cylindrical member 23 has a hollow portion 23d, and the hollow portion 23d communicates with the inner peripheral side space of the insertion portion 23c from the inner peripheral side space of the base portion 23a, and communicates with the housing space 21c of the lid portion 21. A small hole 23e formed by a short tube 23f is provided at the distal end of the insertion portion 23c, and the small hole 23e is used to communicate the hollow portion provided inside the insertion portion 23c with the outside.

Then, the cylindrical small hole 23e at the tip of the insertion portion 23c is sealed by a circular tip film 26a, and a circular intermediate film 26b that seals the hollow portion of the insertion portion 23c is provided at the lower end of the insertion portion 23c, that is, at the upper end of the intermediate portion 23 b. In the insertion portion 23c, that is, in a part of the hollow portion 23d, water 27 is accommodated, and a needle 28 which can be raised and lowered is accommodated. The front end film 26a and the intermediate film 26b are preferably films having good bonding force and capable of being easily broken, such as aluminum films.

The needle 28 has a length that is approximately the same as the distance from the front film 26a to the middle film 26 b. The upper end 28a (see fig. 2) of the needle 28 is inserted into the small hole 23e at the tip of the insertion portion 23c so as to be movable in the axial direction, and a slight gap is left between the upper end 28a and the inner peripheral wall of the small hole 23 e. Further, an ultra-thin flange 28b (see fig. 2) is provided at a position of the upper end portion 28a spaced apart from the front end in the lower end direction by a distance shorter than the length of the small hole 23e, and the flange 28b has an outer diameter slightly larger than the inner diameter of the small hole 23 e. Then, when the warmer 20 is assembled to the body 10, the upper end portion 28a is inserted into the small hole 23e from the hollow portion of the insertion portion 23c, and a gap is formed between the upper end of the upper end portion 28a and the front end film 26 a. When the heating operation of the heating unit 22 is performed, the flange 28b abuts on the front end of the cylindrical tube 23f forming the small hole 23e, and the needle 28 is prevented from moving greatly in the front end direction of the cylindrical member 23.

On the portion of the needle 28 from the upper end 28a to the lower side, 3 or 4 side wings 28c are provided which extend to the lower end of the needle 28. The side wing 28c gradually widens downward. The 3-piece or 4-piece side wings 28c are provided in order not to obstruct the flow of water contained in the insertion portion 23c and to improve the stability of the up-and-down movement of the needle 28. Then, a pressure receiving member 28d is provided at the lower end portion of the needle 28, and the pressure receiving member 28d has an outer diameter slightly smaller than the inner diameter of the lower end portion of the insertion portion 23 c. The pressure receiving member 28d is formed of a shape structure, such as a holed disk or a circular mesh, which is easily subjected to a force from the slider 29 when the slider 29 is pushed up as described later in detail, and which does not prevent the water 27 contained in the insertion portion 23c from flowing down.

When the user operates the heat generation starting device 25, the front end film 26a and the intermediate film 26b are broken, and the water 27 contained in the insertion portion 23c flows down and mixes with the heat generating agent 24 contained in the containing space 21c to start the heat generation reaction.

An example of the heat generation starting device 25 having such a function will be described. The heat generation starting device 25 as illustrated has a slider 29, and the slider 29 is provided with: the housing space 21c is closely attached to the inner surface of the cylindrical inner peripheral wall 21b of the lid 21 and is slidable in the axial direction of the cylindrical member 23. As shown in fig. 2, the slider 29 has a dish-shaped cup 29a and a heat generating agent holding portion 29b provided to protrude from the center of the cup 29 a. The cup 29a has a center side portion 29a1 and an outer peripheral side portion 29a2, and the outer peripheral side portion 29a2 is bent at a boundary portion 29a3 thereof so as to be closer to the heat generating agent retaining portion 29 b. With such a configuration, when the slider 29 approaches the body 10, the cup 29a is caused to slide on the base 23a while maintaining the shape of fig. 1. The heat generating agent holding portion 29b is formed in a cylindrical shape that opens upward, and the heat generating agent 24 is put into and accommodated in the heat generating agent holding portion 29b from the upper opening.

The heat generating agent 24 is composed of calcium oxide (slaked lime) powder, aluminum powder and an additive as main components, or only calcium oxide powder, and is filled in a non-woven fabric bag for use.

The heat generating agent holding portion 29b of the slider 29 has one or more slits (or water passage holes) in the outer peripheral surface. When the slider 29 is pushed up, the intermediate film 26b is broken, so that the water flowing down from the insertion portion 23c passes through the water passage holes of the heat generating agent holding portion 29b and is mixed with the heat generating agent 24 held in the heat generating agent holding portion 29 b.

When the slider 29 is pushed and moved in the direction of the tubular member 23, the upper end portion of the exothermic agent holding portion 29b breaks the intermediate film 26b and further enters the insertion portion 23c to push up the pressure receiving member 28d of the needle 28, so that the upper end portion 28a of the needle 28 protrudes upward from the small hole 23e of the insertion portion 23c, and the distal end film 26a is broken. By the rupture of the intermediate film 26b, the water 27 in the cylindrical member 23 flows into the cup portion 29a of the slider 29, and the hydration reaction with the heat generating agent 24 is started. In addition, the high-temperature water vapor generated by the hydration reaction can be ejected from the small hole 23e at the distal end of the insertion portion 23c into the insertion hole 13b of the body 10 by the rupture of the distal end film 26 a.

When the heat generating agent 24 is mixed with the water 27, heat generation starts immediately. At about 25 ℃ at room temperature, about 45 ℃ is reached after 4 minutes. The action for starting the heat generating action is only a simple action of pushing up the slider 29, and the mixing speed of the heat generating agent 24 and the water 27 is always kept constant. Therefore, the inner layer portion 13 can be heated to a predetermined temperature for a substantially constant time whenever the user uses the heat-resistant sheet at any time.

The inner layer 13 is heated by the conduction heat of the heated water or steam inserted into the insertion portion 23c of the insertion hole 13b and the convection heat of the steam injected into the insertion hole 13b, so that the heating efficiency is high and the temperature can be reached in a short time. Further, when the inner layer portion 13 is made of an elastic body, the inner layer portion 13 is covered with the outer layer portion 12 having a high heat insulating property because the heat capacity is large, and therefore the suitable temperature holding time after the end of heating can be made long. Therefore, it is possible to avoid the temperature of the inner layer portion 13 becoming lower than the body temperature during use. Further, the water droplets adhering to the inner wall 13a due to the water vapor jetted into the insertion hole 13b have an effect of improving lubricity of the inner wall 13 a.

[ second embodiment ]

In the case of the first embodiment, when the medical sperm collecting apparatus T is used, since it is necessary to grip the main body 10 and push up the slider 29 at the bottom, the operability is not good. Accordingly, in the preferred second embodiment of the present invention (see fig. 3 to 8), the heat generation starting device 25 is configured to be easier for the user to operate. Hereinafter, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted for the sake of simplicity.

The heat generation starting device 25 includes a pusher 30 and a bottom film 31 in addition to the slider 29 of the first embodiment. As shown in fig. 3 to 6, the heat generation starting device 25 includes a slider 29 provided slidably in the axial direction of the tubular member 23, a pusher 30 provided below the slider 29, and a bottom surface film 31 disposed below the pusher 30. The pusher 30 is movable between a position not protruding from the bottom surface of the lid portion 21 and a position protruding on the outside of the slider 29 (the side of the slider 29 opposite to the cylindrical member 23), and has the following functions: when rotated in a protruding state, the slider 29 cannot move relative to the slider 29, and when the slider 29 is pushed in a direction to approach the main body 10 in the immovable state, the slider 29 is slid in the direction of the cylindrical member 23.

Unlike the first embodiment, the bottom of the slider 29 is provided with a horizontal plate-like receiving member 29 c. The outer peripheral surface of the receiving member 29c slidably abuts against the inner surface of the inner peripheral wall 21b of the cover 21. Between the center of the receiving member 29c and the outer periphery of the receiving member 29c, 3 circular holes 29d are formed at equal intervals on a circle concentric with the center of the receiving member 29 c.

The pusher 30 has a bottom plate 30a having substantially the same diameter as the receiving member 29c of the slider 29. In the example of fig. 2, the three-prong shape is formed for weight reduction, but the three-prong shape may be formed in a disc shape. Then, a push-up member 30b extending upward is provided at a position where the distance from the center of the bottom plate 30a is the same as the distance from the center of the slider 29 to the hole 29 d. The push-up members 30b are the same in number as the holes 29d of the slider 29 and are disposed at equal intervals on a circumference centered on the center of the bottom plate 30 a.

In the illustrated example, a convex portion 30d protruding upward is provided in the center of the bottom plate 30a of the pusher 30. When the pusher 30 is held at a position not protruding from the bottom surface of the lid portion 21, the convex portion 30d abuts against the bottom portion of the heat generating agent holding portion 29b of the slider 29 and holds the slider 29 at an appropriate height, or is provided for setting the position of the bottom plate 30a of the pusher 30 with respect to the bottom surface of the lid portion 21. The convex portion 30d is preferably provided therein with a concave portion 30e opening outward (bottom surface).

As shown in fig. 3, due to the above-described configuration, in the state before completion (before sale) of the medical sperm collecting apparatus T, the front ends of the respective push-up members 30b of the pusher 30 are inserted into the respective holes 29d of the slider 29, and the pusher 30 can be moved in the direction of the slider 29. Then, the convex portion 30d of the bottom plate 30a of the pusher 30 abuts against the bottom portion of the heat generating agent holding portion 29b of the slider 29, and the pusher 30 can be stopped in a state where the upper end portion of the push-up member 30b of the pusher 30 abuts against the bottom surface of the cup portion 29a of the slider 29. At this time, the bottom surface of the bottom plate 30a of the pusher 30 and the bottom surface of the lid portion 21 are located on the same plane. Then, as an example, the bottom film 31 made of plastic is bonded so as to be peelable so as to cover the bottom plate 30a of the pusher 30 and the bottom surface of the lid 21. In this state, the market is provided.

Then, when the medical sperm collecting apparatus T of the second embodiment is used, the bottom surface film 31 in fig. 3 is peeled off, and the finger tip is put into the concave portion 30e of the pusher 30, and when the pusher 30 is pulled out, as shown in fig. 5, the upper end portion of the push-up member 30b abuts against the slider 29, and the pusher 30 stops at a predetermined position. When the pusher 30 is rotated in a predetermined direction around the axis of the main body 10 in this state, the push-up member 30b of the pusher 30 moves in the longitudinal direction thereof within the hole 29d of the slider 29, and the upper end portion of the push-up member 30b engages with the hole 29d, so that the pusher 30 is fixed so as not to be movable in the vertical direction with respect to the slider 29 in a state of protruding from the bottom surface of the lid portion 21.

An example of such a configuration will be described in detail with reference to fig. 7 and 8, in which the pusher 30 is stopped at a predetermined position when the pusher 30 is pulled out, and the pusher 30 is fixed so as not to be movable in the vertical direction with respect to the slider 29 in a state of protruding from the bottom surface of the cover portion 21 when the pusher 30 is rotated in a predetermined direction. Fig. 7 (a) mainly shows the shape of the hole 29d of the slider 29, and fig. 7 (b) mainly shows the shape of the push-up member 30b of the pusher 30. Fig. 8 shows the functions of the hole 29d of the slider 29 and the push-up member 30b of the pusher 30.

As shown in fig. 7, each hole 29d of the slider 29 is formed so that a half of the length in the circumferential direction is wide and the other half in the same circumferential direction is narrow. Then, the outer side edges of the holes 29d with respect to the center of the receiving member 29c are located on the same circumference, but the inner side edges of the narrow portions 29d2 of the holes 29d with respect to the center of the receiving member 29c are located on the same circumference closer to the outer side than the inner side edges of the wide portions 29d1 of the holes 29d with respect to the center of the receiving member 29 c.

The push-up members 30b of the pusher 30 are provided at equal intervals on the circumference centering on the center of the bottom plate 30a, in the same number as the holes 29d of the slider 29. The horizontal cross-sectional shape of each push-up member 30b is an arc having the same curvature as the arc of the hole 29d of the slider 29, and the length in the circumferential direction is substantially half the length of the hole 29d of the slider 29. As shown in fig. 8, each push-up member 30b integrally has a thick-walled portion 30b1, a thin-walled portion 30b2, and a bent portion 30b3, wherein the thick-walled portion 30b1 extends upward from the lower end to the vicinity of the upper end of the push-up member 30b, the thin-walled portion 30b2 is formed on the upper side of the thick-walled portion 30b1, and the bent portion 30b3 protrudes outward from the upper end of the thin-walled portion 30b 2. Also, the thickness of the thick-walled portion 30b1 is substantially equal to the width of the wider portion 29d1 of the hole 29d of the slide member 29, and the thickness of the thin-walled portion 30b2 is substantially equal to the width of the narrower portion 29d2 of the hole 29d of the slide member 29. The thick wall portion 30b1 and the outer side surface of the thin wall portion 30b2 are located on a vertical curved surface, and a horizontal land 30b4 is formed at the boundary between the inner side surface of the thick wall portion 30b1 and the inner side surface of the thin wall portion 30b 2.

As shown in fig. 3 and 8 (a), according to the above-described constitution, in the unused state of the medical sperm collector T, the thick wall portion 30b1 of the push-up member 30b of the pusher 30 penetrates the wide portion 29d1 of the hole 29d of the slide member 29, and the thin wall portion 30b2, the mesa 30b4 and the curved portion 30b3 are located above the receiving member 29c of the slide member 29. In this state, the pusher 30 cannot rotate about its central axis, but can be pulled downward. Also, as shown in fig. 5, when the pusher 30 is pulled out downward from the lid portion 21, as shown in fig. 8 (b), the thin-walled portion 30b2 of the push-up member 30b is located on the wider portion 29d1 of the hole 29d of the slider 29, so in the case of fig. 7 (a), the pusher 30 can rotate in the clockwise direction about its central axis. As shown in (c) in fig. 8, when rotated, the thin-walled portion 30b2 of the push-up member 30b moves onto the narrower portion 29d2 of the hole 29d of the slider 29, while the bent portion 30b3 abuts on the upper surface of the receiving member 29c forming the narrower portion 29d2 of the hole 29d, and the land 30b4 abuts on the lower surface of the receiving member 29 c. As a result, the pusher 30 cannot move up and down with respect to the slider 29.

The medical sperm collecting apparatus T in this state is placed on a flat surface such as a table in an upright state, and the main body 10 is pushed downward. Then, as shown in fig. 6, the pusher 30 and the slider 29 are raised in the housing space 21c of the cover 21 in a connected state. At this time, when the slider 29 is raised to a position where the periphery of the cup portion 29a of the slider 29 is in close contact with the top wall of the base portion 23a of the tubular member 23, the upper end portion of the heat generating agent holding portion 29b of the slider 29 breaks the intermediate film 26b at the lower end portion of the insertion portion 23c, and therefore the water 27 in the insertion portion 23c flows down. The needles 28 in the insertion portion 23c are pushed up by the upper end portions of the raised heat-generating agent holding portions 29b, and the upper end portions 28a of the needles break the distal end film 26 a.

When the body 10 is pushed downward to cause the water 27 to flow downward and come into contact with the heat generating agent 24, heat generation is started in the same manner as in the case of the first embodiment, and as shown in fig. 6, the high-temperature steam 32 is jetted from the tip of the tubular member 23 into the insertion hole 13b of the body 10, and the inner layer 13 can be heated to a suitable temperature in a short time of about 4 to 5 minutes from the time when the body 10 is pushed downward.

When the heating is completed for a predetermined time by the warmer 20, the warmer 20 is pulled to be separated from the body 10 in a state where the body 10 is tilted downward and the warmer 20 is tilted upward, or vice versa, by holding the body 10 with one hand and the warmer 20 with the other hand. Since the bottom surface of the lid 21 and the bottom surface of the pusher 30 are positioned on the same plane, the separated warmer 20 can be placed in a state where the cylindrical member 23 is standing on an arbitrary plane, that is, in a stable state.

In this way, the main body 10 with the heater 20 removed can be used with at least the inner portion 13 kept at an appropriate temperature.

[ other embodiments ]

The shape of the cup 29a of the slider 29, the shape of the heat generating agent holding portion 29b, the positional relationship with the cup 29a, the shape of the pusher 30, and the connection structure with the slider 29 are not limited to the above examples. Any shape and structure may be adopted as long as it has the following structure: the slider 29 moves to drop water in the insertion portion 23c of the tubular member 23, and the water contacts the heat generating agent to generate heat, whereby water vapor is ejected from the tubular member 23 into the insertion hole 13b of the main body 10.

In addition, as for the heat generating agent, a heat generating agent that generates heat by an oxidation reaction such as iron powder may be used instead of the heat generating agent that generates heat by a hydration reaction as described above. However, in this case, the following structure may be adopted: a structure in which a heat generating agent is put in a bag having high airtightness, and when the slider is pushed up, the bag is broken and brought into contact with oxygen, and water is heated by the heat generation to generate steam. In addition, a heat generating agent which generates heat by friction or the like may be used instead of heating a liquid such as water. In this case, no liquid such as water is required.

In the above embodiment, the main body 10 and the warmer 20 may be sold in a combined state, or both may be sold separately. The medical sperm collecting device described above is preferably used for medical use or the like with collected sperm, but may be discarded in a state where sperm is placed therein. The body 10 and the warmer 20 have a cylindrical shape, but may have other shapes such as a quadrangular prism shape. The liquid in warmer 20 is water, but may be a mixed liquid of water and other additives, or may be a liquid other than water.

The length of the insertion portion 23c of the tubular member 23 is preferably about 50% to 60% of the length of the insertion hole 13b, but may be 40% to 80%. The insertion portion 23c is preferably tapered toward the distal end as described above, but may be substantially the same in thickness as the distal end hole. The insertion portion 23c has a cylindrical shape, but may have another shape such as a triangular prism shape.
