Description

GITTA PERCHA POINT-CUTTING APPARATUS}

The present invention relates to a dental appliance, and more particularly, the remainder of a geographic pointer (GP: silicone dental material called GUTTA PERCHA POINT) that is planted in the site where the nerve of the rotten area is removed before the prosthesis of the rotten teeth. It relates to a dental instrument for the cutting of the paper to make it easy to remove the.

In general, when the teeth of the human body is decayed or inflamed nerve parts due to trauma, etc., go to the dentist to be treated, to remove the infected nerves of the root of the teeth for protection of the teeth, root canal to the site where the nerve is removed The filler is inserted to protect the nerve from the risk of infection again. As the root canal filling agent, a material called a GUTTA PERCHA POINT, which is generally made of silicon, is used. Hereinafter, a process of inserting such a paper pointer will be described with reference to the drawing of FIG. 1 (and the following will be called abbreviated as the paper pointer).

As shown, when the tooth 1 is decayed, the gum 3 is inflamed, and this inflammation causes the nerve 1b located at the root of the tooth 1 to be infected.

The therapist cuts out the rotten portion 1a and removes the nerve 1b located inside the root of the tooth 1 by using the coil removal device 4. Inside the root of the tooth (1) from which the nerve (1b) has been removed is inserted into the paper (5) of the silicon material is useless to the human body. After inserting the zip 5, after removing the remaining portion 5a of the zip protruding from the root of the tooth 1, the interior of the body of the tooth 1 is filled with the amalgam 6 or the like. The treatment in 1) is completed.

In order to remove the remaining portion (5a) of the endothelium protruding to the root of the tooth (1) during the above process is used for the physique cutting. This paper cutting mechanism will be described with reference to FIG.

As shown, at the tip of the body 12 of the instrument 10, a nichrome wire 16 for removing the remaining skin portion protrudes through the gypsum 14. In addition, an electric cord line 18 is formed at a rear portion of the body 12 to supply power for heating the nichrome wire 16. In order to use the device 10, the nichrome wire 16 is connected to the electric cord wire 18 by the electric power transmitted by plugging the electric cord wire 18 into a socket (not shown) formed in a dentist's chair (not shown). Is heated to reach a constant temperature. In the above state, the user grasps the body 12 and cuts and removes the remaining epidermis planted inside the tooth with the heated nichrome wire 16.

However, the conventional paper cutting device 10 as described above has the following problems. First, by plugging it into a dentist's chair, the power supplied to the lamp installed in the dentist's chair is insufficient, causing the lamp to flicker or breakdown during treatment, making it difficult for the patient to be treated, and the dentist's expensive equipment easily breaks down. There was this.

In addition, the use of a device for treating a patient is very inconvenient because the electric cord wire 18 is caught on the arm of the therapist and the movement of the device 10 is not free. There was a problem falling inside. For the same reason as above, such an electric cord type device is currently rarely used.

In order to solve the above problems, the presently used for cutting the paper is to remove the remaining portion of the paper by using a tweezers-type device (20). This mechanism is shown in Figure 3, the user heats the tip tip 22a portion of the tweezers 22 to the alcohol lamp 24 to reach a predetermined temperature, and then to the heated tip 22a portion. This will remove the remainder of the skin. Such a tweezers-type device 20 is not a failure of the dentist, the difficulty of treatment by the electric cord wire, etc., but currently widely used, but there are various problems as follows.

An alcohol lamp 24 is required to heat the tip 22a portion of the tweezers-type device 20, which is inconvenient to operate every time it is used, as well as placed on the shelf of the dentist. The alcohol lamp 24 has a problem that the risk of fire always exists.

In addition, the tip 22a portion may accidentally burn the patient's mouth while delivering the heated tweezers 22 to the doctor, and the tip 22a portion when the tweezers 22 are dropped or time is delayed. It is difficult to remove the remaining parts of the dermis because the temperature of the lowering is lowered, and the dermis itself, which is planted inside the tooth root, sticks to the tip (22a) and comes out again. There is a problem that can not feel the confidence.

Accordingly, an object of the present invention is to solve the above problems, to provide a dental appliance for zip cutting to operate by wireless charging and to provide a constant temperature at all times to remove the remaining parts of the skin easily and safely. will be.

Another object of the present invention is to change the nichrome wire structure of the tip portion to be inserted to remove the remaining epidermis in order to remove the remaining portion of the epidermis for the dermis of the dermis cutting so that all the remaining portion of the dermis in one operation can be removed To provide a mechanism.

As described above, the dental appliance for cutting a paper for achieving the object of the present invention, the tip portion is provided with a nichrome wire adjusted to a predetermined length so as to exhibit a temperature of about 100 to 110 ℃, to remove the remaining portion of the skin It is installed inside the rear part of the main body having a skin removal unit, a switch for controlling the on and off control electrically connected to the skin removal unit, and the rear of the main body to supply power for the operation of the skin removal unit and repeat by charging It is composed of a rechargeable battery part that can be used, and the technical subject is to remove the skin by using the nichrome wire of the tip portion heated by the power supplied from the battery by the on operation of the switch.

In addition, the dental appliance according to the present invention may further include a dedicated charger for charging the battery unit.

The paper removal unit is connected to each other in communication with the interior of the body portion and inclined downward to about 10 to 20 °, a protective material made of a Teflon synthetic resin of a heat-resistant material connected to the tip of the body, and the body through the inside of the body It is preferable to be made of nichrome wire that is electrically connected to the negative switch and penetrates the protective material and has a skin removing space at the tip of the protective material. More preferably, the paper removing space has an arc shape having a diameter of 2 to 3 mm. do.

In addition, the main body portion, in conjunction with the operation of the switch to install a lamp indicating whether the operation of the mechanism, the main body portion, so that the charging pin connected to the charging battery installed therein is installed on the rear.

Therefore, there is an advantage that can be removed more effectively and simply because the battery is always maintained a constant temperature by a charging battery without a separate electric cord wire, and has a size suitable for the skin removal area.

Hereinafter, with reference to the drawings showing a preferred embodiment of the dental instrument for zip cutting according to the present invention described above in more detail.

Figure 4 is a perspective view of the dental instrument for zip cutting according to the present invention, Figure 5 is an internal cross-sectional view. As shown, the apparatus 100 according to the present invention includes a main body 110 having a large skin removal unit 120 and a switch 112 for the operation of the ground skin removal unit 120. And it is composed of a battery 130 for supplying power for operation.

First, the main body 110 is made of a cylindrical shape, the charging battery 130 is installed inside the rear. The rechargeable battery 130 is configured to be in close contact with the rear inner surface as a power supply and connected with the charging pins 132 installed on the rear outer surface of the main body to be charged. That is, in the present invention, since the wireless battery is used as a power supply and uses a charging battery 130 that is capable of charging and discharging, the battery for charging 130 installed therein is supplied with power using a separate charger. It is electrically connected to the charging pin 132 to be charged using the power supplied from the charger.

In addition, the front side of the main body 110, so that the switch 112 protruding to the outer surface is installed. The power supplied from the battery 130 is adjusted according to the on and off of the switch 112. Since the electrical configuration of the switch 112 is a general technique well known in the art, a detailed description thereof will be omitted.

On the other hand, an LED lamp 114 is installed in the front portion spaced apart from the switch 112 by a predetermined interval. The stamp 114 is electrically connected to interlock with the operation of the switch 112 so that the lamp is lit when the switch 112 is in the on state, and is not lit when the switch 112 is in the off state. Therefore, the user can easily know whether the device is malfunctioning because the operation of the device can be known depending on whether the lamp 114 is lit.

Next, the skin removal unit 120 will be described with reference to FIG. 6. The body 122 communicates with the inside of the main body 110 and is inclined downward at the front end of the main body 110. The body 122 is formed to be inclined downward by about 10 to 20 ° with respect to the horizontal plane of the main body 110 to smoothly remove the paper. That is, for the treatment of the teeth located inside the oral cavity, the user grasping the body portion 110 and allowing the portion of the dermis removing portion 120 to be injected into the oral cavity, the tip of the portion of the removing portion 120 is inserted into the tooth. Since it should be inclined with respect to the body portion 110 as described above it can be made easily this operation. In addition, the body 122 has a conical shape in which the inner diameter gradually decreases from the main body part 110 toward the lower part thereof. This is also to allow easier insertion into the tooth located inside the oral cavity as described above.

Next, a protective material 124 made of Teflon material is installed at the front end of the body 122. The reason why the protective material 124 is made of Teflon is to allow the nichrome wire 126 to be described later to withstand high temperature without deformation. That is, since the nichrome wire 126 needs to be heated in order to remove the remaining part of the skin, it can withstand the heating temperature of the nichrome wire 126 sufficiently, and since it should not be deformed, it is composed of Teflon which is a heat resistant synthetic resin material will be.

In addition, a nichrome wire 126 for removing the skin is installed at the tip of the protective material 124 made of Teflon. The nichrome wire 126 is formed so that the skin removal space 126a is formed in a circular shape in the front portion consisting of two straight lines. The inner diameter of the skin removing space 126a is about 2 to 3 mm. The reason for forming the skin removal space 126a in a circular shape and having a constant diameter as described above is to remove the skin effectively. That is, in order to remove the residual portion of the epidermis planted in the nerve part inside the tooth, it is preferable that all of the residual portion is removed in one operation. For this purpose, the residual portion can be inserted into the dermal removal space 126a. Because it has to have the shape and size.

On the other hand, the nichrome wire 126 is electrically connected to penetrate the above-described protective material 124 to receive the power supplied from the battery through the body 122. In addition, the nichrome wire installed inside the body Should be protected by Teflon coating. Therefore, the Teflon coating blocks the heat transfer even by the heat of the nichrome wire, so that the heat transfer is not performed by the heat of the nichrome wire to the body.

In addition, the exothermic temperature of the nichrome wire 126 is adjusted to be about 100 to 110 ℃, because the temperature can be smoothly removed. That is, if the exothermic temperature of the nichrome wire 126 is too high, it may cause damage to the teeth, and if the temperature is too low, the skin removal is not performed well, so that the exothermic temperature of the nichrome wire 126 is adjusted appropriately. The adjustment of this temperature is adjustable as the length of the nichrome wire 126. In general, the resistance of a conductor due to electricity applied to the conductor depends on the thickness and length of the conductor. That is, since the electrical resistance of the conductive wire is proportional to the length of the conductive wire and inversely proportional to the cross-sectional area, it is preferable to adjust the exothermic temperature of the nichrome wire 126 to 100 to 110 ° C by appropriately adjusting the thickness and length of the nichrome wire 126 to be installed. It is possible.

As described above, in addition to controlling the heating temperature of the nichrome wire 126 by adjusting the length of the nichrome wire 126, a separate overload prevention circuit (not shown) is installed in the battery unit 130 to provide the nichrome wire 126. When the temperature is above a certain temperature, the supplied power may be cut off. That is, in case the nichrome wire 126 generates more heat than necessary due to a malfunction of the device, an overload circuit is installed as described above, and a battery 130 having an overload circuit for controlling temperature is widely available on the market. In addition, since the electrical configuration is a general technique well known in the art, a detailed description thereof will be omitted.

On the other hand, it is also possible to configure the skin removal unit different from the above. This alternative embodiment will be described with reference to the drawing of FIG. 7.

In this embodiment, the nichrome wire 126 is not protected by a separate Teflon, but has a structure wrapped by the gypsum 125. In the case of using the gypsum 125 as described above, the gypsum 125 is installed through the body, and two nichrome wire passages are formed in the gypsum 125. And the nichrome wire 126 is installed through the passage, so that the end of the gypsum 125 coincides with the end of the skin removal unit 120. Therefore, in the present embodiment, a separate protective material is not required, and since the nichrome wire 126 installed inside the body 122 does not need to be coated with a separate Teflon film, a simpler structure can be achieved. And since the end of the gypsum does not protrude to the outside, the gypsum powder does not fall into the oral cavity during treatment. On the other hand, gypsum 125 is not only easier to manufacture than the above-described Teflon but also less thermally conductive, so in the above structure, the heat transfer to the inner surface of the body 122 by heat of the nichrome wire 126 is more. It can be suppressed.

Next, the operation and effects of the present invention configured as described above will be described with reference to FIG.

As shown, when the instrument 100 is not used or when the battery installed inside the main body 110 is discharged, the instrument 100 is charged to the charger 200. The charger 200 is used whenever necessary for the treatment of the patient while the user is placed in a convenient position, for example, a dentist. When the instrument 100 is used for the treatment of the patient, the user winds the body 110 with his hand and presses the switch 112 in front of the body 110 with his thumb to operate the instrument. That is, the current supplied from the battery by pressing the switch 112 is electrically energized to supply the current to the LED lamp 114 and the nichrome wire 126. If the battery is discharged because the LED lamp 114 does not light, so the user can check it by eye, it is easy to check whether the operation.

The nichrome wire 126 located at the tip of the paper removal unit 120 generates heat by the operation of the switch 112. In this case, the thickness and length of the nichrome wire 126 are adjusted in advance so that the nichrome wire is applied by the applied current. Exothermic temperature of 126 is to maintain a constant temperature to 100 to 110 ℃. The working instrument is inserted into the tooth to remove the remaining epidermis planted inside the tooth. In this case, since the skin removal unit 120 has a predetermined inclination with respect to the main body unit 110, the skin removal unit 120 can be smoothly inserted into the tooth. The remaining portion of the skin is inserted into the skin removal space 126a of the nichrome wire 126 formed at the front end of the skin removal portion 120 inserted into the tooth. That is, the user removes by twisting the user with a slight force in the state in which the remaining skin part to be removed is inserted into the skin removal space 126a. At this time, since the temperature of the nichrome wire 126 is always maintained at a constant temperature, by the temperature, the part of the skin made of silicon material can be easily melted and removed in a single operation. In addition, since the nichrome wire 126 is protected by the protective material 124 made of Teflon or wrapped by the gypsum 125 installed inside the body, the problem that the gypsum powder falls into the oral cavity as in the related art can be solved. do.

After removing the remaining portion of the paper as described above, by taking out the mechanism 100 to stop the operation of the switch 112 to stop further consumption of power. In addition, the remaining portion of the zip skin attached to the nichrome wire 126 is washed off, and the battery is left in the charged state or the battery is placed in the charger 200 so as to be used again through the above-described process. Done.

As described above, since the mechanism according to the present invention for removing the remaining portion of the paper is made wirelessly by the rechargeable battery, the risk of fire is eliminated, it is convenient to use, and the constant power is always maintained. By maintaining the temperature, there is an effect that can be conveniently used to remove residual skin.

In addition, the mechanism according to the present invention can not only remove the skin removed by the skin removing space formed at the tip end in one operation, but also prevent the impurities such as gypsum from falling into the oral cavity.

In addition, since the skin removal portion forms a certain inclination with respect to the main body portion, the user can insert the skin removal portion more easily in the tooth insertion, so there is another effect that the operation can be made more convenient.
