2. Description of the Related Art A piercer body for accommodating and holding a piercing needle in a cartridge, and a stopper holder for holding the stopper in front of a piercing needle holding position of the piercer body are provided. Piercers are generally known in which an earlobe is interposed between the body and a piercing needle which is pushed out by a plunger so as to pierce the earlobe and fit into a stopper.

[0003] For example, Japanese Utility Model Laid-Open No. 4-89014 discloses a piercer made of synthetic resin in which a piercer body and a stopper holder are connected in a U-shape. In this piercing device, a cartridge and a plunger are inserted into a cylinder of the piercing device main body, and the piercing needle is pushed out of the piercing needle holding portion together with the cartridge by pushing the plunger with a finger from the back thereof.

The cartridge is of a truncated cone shape divided into two parts on the axis, and the piercing needle portion is held on the mating surface at the front end of the cartridge, and the needle portion is largely projected forward from the cartridge. In this way, when it is pushed out of the cylinder by the plunger, it is divided into two. Therefore, in this case, the piercing needle advances substantially linearly by the movement of the cartridge being guided by the cylinder.

Japanese Patent Application Laid-Open No. Hei 6-113910 discloses that a detachable cartridge is held at a fixed position on the front surface of a piercer body, and a plunger is inserted into the cartridge from the rear surface by a rack and pinion mechanism to insert a piercing needle. It is described that the cartridge is extruded from a cartridge. The cartridge has two vertically arranged cartridges.
Two piercing needle accommodating holes, two opposing needle supporting portions project inward from the front opening edge of the accommodating hole so as to face each other on the axis, and piercing needles are formed at opposing concave portions formed at the protruding ends. The needle portion is held. In this one,
Even if the plunger is advanced, the cartridge itself does not move, and the piercing needle moves straight when the needle portion is guided by the needle holding portion.

[0006]

However, the former of the above prior arts has a problem that if the cartridge is slightly inclined in the cylinder, the position of the tip of the piercing needle projecting forward from the cartridge is largely shifted. is there.

In the latter of the prior arts described above, although the piercing needle has good linear guideability, when the head is pushed out of the cartridge through the needle holding portion at the front end thereof, the needle holding portion is pushed out. There is a problem that fragments are scattered.

[0008]

This interval is set to a predetermined force (the earlobe can be easily removed from between the earpiece 20 and the earpiece 30) by the earpiece 20 of the cartridge 3 and the earpiece 30 of the stopper holder 4, assuming that the earlobe is thin. Is set so that it can be pinched with a force that does not separate it.

[Use of Piercer] The piercing needle 13 is housed in the cartridge 3 and put in a sterile bag. Stopper 16
Are held by the stopper holder 17 of the stopper holder 4. The stopper 16 is held by the stopper holder 4 by the resilient engagement of the holding portions 16c, 16c with the left and right engagement ridges 17b, 17b, and thus detaches from the stopper holder 4 by vibration or the like. Never.

In use, the plunger 5 is pulled backward against the bias of the spring 29, and when the step between the small diameter portion 5a and the large diameter portion 5b reaches the rear side of the release accommodating portion 26, the release 6 is released. Is moved upward by the bias of the spring 36, and the engaging portion 23 engages with the step portion to hold the plunger 5 at the rear position.

In this state, the cartridge 3 accommodating the two piercing needles 13, 13 is mounted on the cartridge mounting portion 7 of the fixed body 1, and the stopper holder 4 holding the two stoppers 16, 16 is movable. The body 2 is mounted on the fastener mounting section 9. The stopper holder 4 may be mounted on the movable body 2 in advance.

Then, the grip portion 8 and the lever 12 are gripped together with one hand, and an earlobe is inserted between the cartridge 3 of the fixed body 1 and the stopper holder 4 of the movable body 2. When the lever 12 is pulled toward the grip portion 8, the distance between the cartridge 3 and the stopper holder 4 is reduced, and the stopper 44 of the movable body 2 is positioned in front of the release housing 26 of the fixed body 1 as shown in FIG. 4, the distance between the cartridge 3 and the stopper holder 4 becomes constant as shown in FIG. 4, and both of them hold the earlobe A.

More specifically, the earlobe A is sandwiched from the front and rear by the earpiece 20 of the cartridge 3 and the earpiece 30 of the stopper holder 4. In this pinching, when the earlobe A is thin, the earpieces 20 and 30 slightly bite into the earlobe A and hold the earlobe A so as not to easily come off. When the earlobe A is thick, the bite is large. And keep this.

While holding the earlobe A, the thumb is hung on the finger hook 24 of the release 6 projecting from both sides of the fixed body 1 and the release 6 is lowered. As a result, the holding of the plunger 5 by the release 6 is released, the plunger 5 advances by a certain force by the bias of the spring 29, enters the housing hole 14a of the cartridge 3, and pushes out the piercing needle 13 from the cartridge 3.

Even if the earlobe A is thin, the earlobe A is securely held between the earpiece 20 and the earpiece 30. Therefore, even if the piercer is slightly shaken when the release 6 is lowered, the earlobe A and the piercing needle 13 of the cartridge 3 can be moved. And there is no deviation in the positional relationship between the stopper 16 and the stopper holder 4,
The piercing needle 13 penetrates the predetermined piercing position of the earlobe A and fits into the stopper 16.

At this time, the piercing needle 13 is
The advance of 3a is guided by the accommodating hole 14a of the cartridge 3, and the advance of the needle portion 13b is guided by the needle hole 10a of the needle holding portion 10 of the cartridge 3, so that it advances straight. Then, as shown in FIG.
The head 13a of the cartridge 3 is a
In the case of zero, this will be spread outward. that time,
Since the tips of the needle holding portions 10 and 10 are not joined to each other, the needle holding portions 10 and 10 are bent (as a starting point) around the weakly formed root thin portions 10b and 10b without being broken in the middle. Therefore, the needle holder 10 does not break from the main body 14 and scatter around.

The small diameter portion 13 d of the piercing needle 13 is
Engaging with the holding portions 16c, 16c of the
When the interval of 6c is widened, the engagement between the holding portions 16c, 16c and the engaging ridges 17b, 17b of the stopper holder 4 is released, and the stopper 16 comes off from the stopper holder 4. Therefore, after the piercing needle 13 is fitted to the stopper 16, the distance between the cartridge 3 and the stopper holder 4 is widened by loosening the pull of the lever 12 of the movable body 2 and the entire piercing needle is pulled downward. 13 and the stopper 16 remain on the earlobe side, and the piercer is removed.

Since the plunger 5 has its forward end regulated by the first stopper surface 31 inside and the second stopper surface 32 outside the cylinder portion 25, the piercing needle 13 is not excessively pushed out. At the forward end, the momentum of the plunger 5 is dispersed by the inner and outer stopper surfaces 31 and 32 of the cylinder portion 25 and absorbed by the first and second shock absorbers 33 and 34, so that sound is generated. Is hardly emitted, and the user is not surprised by the collision sound.

Further, in the case of the above embodiment, since the finger contact surface of the finger hook 24 of the release 6 is inclined backward and downward,
Since the thumb is easily applied to the finger hook 24 while the grip portion 8 and the lever 12 are gripped, the force applied to the release 6 can be easily adjusted in combination with the fact that the release 6 operates in the vertical direction, and the operability is improved. Excellent.

After piercing the piercing needle 13 into one earlobe of the user, the advancing plunger 5 is pulled backward and held by the release 6, and the cartridge 3 and the stopper holder 4 are attached to the respective mounting portions 7. , 9, and re-attached with the respective ears upside down, and pierce the other ear lobe with the piercing needle 13 as before.

[Another Example of Needle Holder] As shown in FIG.
In this example, the needle holding portions 10 and 10
Both side portions of 0c and 10c are tapered and connected to each other via a thin portion 10e.

In the case of this example, when the needle holding portions 10 and 10 are pushed by the head 13a of the piercing needle 13, the thin portion 10e is broken and the tapered portions 10d and 10d are vertically divided and bent from the root. become.
