Abstract

PROBLEM TO BE SOLVED: To provide a tooth extraction tool which can twist a tooth without being affected by or affecting adjacent teeth during tool extraction.SOLUTION: A tooth extraction tool is formed of a screw part to be screwed into a tooth and a handle part. A rod-like body, which is extremely flexible and can be bent, is provided at an apex of the handle part. With the handle part, the screw part is screwed into a hole in a center part of the tooth, then when the screw part sufficiently bites into the tooth, the tooth is extracted with the handle part. In doing so, since a tooth root is twisted and floats from an alveolar bone, tooth extraction is relatively easy and safe. Also, because force for tooth extraction is applied to only the tooth to be extracted, tooth extraction is not affected by and does not affect adjacent teeth. If fingers gripping the handle part slip, a user can grip the rod-like body, so that falling of the tooth extraction tool hardly occurs.SELECTED DRAWING: None

Description

  The present invention relates to a tooth extraction tool that can perform tooth extraction safely and easily and reduces the burden on the patient.

  In the case of tooth extraction in conventional dental treatment, a toothbrush is inserted between the tooth and the alveolar bone at the site of the periodontal ligament to dislodge the tooth, and then the dental It is common to pick out the teeth with forceps (pliers).

  Examples of the above-described forceps are described in detail in JP-A No. 2002-291553, and examples of the forceps are described in detail in JP-A No. 2009-119095.

Japanese Patent Application Laid-Open No. 2002-291553 (FIG. 1) JP2009-119095 (FIG. 15)

  However, if a tooth is accidentally pushed in when it is squeezed with an insulator, this may cause nerve damage, blood vessel damage, increased bleeding, or alveolar bone depression. There is a problem. Therefore, it is an object of the present invention to make it possible to extract teeth more safely and easily so that such problems are less likely to occur.

  Prior to solving the above problem, the inventor is weak in the twisting force, and can be lifted from the alveolar bone relatively easily when twisted, so that it is possible to easily extract the tooth by pulling it out. I got the knowledge. Therefore, any extraction tool can be used as long as it can twist a tooth without using an insulator for extraction and without being affected or affected by adjacent teeth.

  In view of this, the present invention provides a tooth extraction tool comprising a screw portion for screwing into a tooth and a handle portion, and having a non-slip portion on the handle portion. Furthermore, a tooth extraction tool is provided in which the handle portion is provided with a fall prevention tool.

  The usage and action are as follows. When the screw part is screwed into the hole at the center of the tooth with the handle part, the screw part bites into the tooth firmly, so that the handle part is picked with a finger or sandwiched between the jaw parts of the forceps and pulled out. At this time, the tooth root is twisted and floats from the alveolar bone, so that tooth extraction is relatively easy and safe. Further, since the extraction force is applied only to the tooth to be extracted, it is less likely to be affected or influenced by the adjacent teeth.

  Since the handle portion has a non-slip portion, it is possible to effectively exert on the screw portion, that is, the tooth, a force picked by a finger or pinched with forceps.

  On the other hand, since it is a tooth extraction tool used in the oral cavity, the fingertip may unintentionally slip from the anti-slip portion and remove the tooth extraction tool. If this is picked up, there is no problem, but if this is not good, a fall prevention tool is useful. Due to this, even if the hand slips, the tooth extraction tool is less likely to be removed. As an example of the fall prevention tool, a string wrapped around a finger, a string passed between a thumb and an index finger, and a flexible and bendable rod-like body described later are raised.

  Next, the anti-slip portion may be a hole or a hook portion formed in the handle portion. The tip of a forceps or a jig can be securely hung on this hole or hook.

  Further, the anti-slip portion may be a step portion formed between the screw portion and the handle portion. It is possible to firmly hang a finger, forceps, or the tip of a tool on this step. What formed the side opposite to the screw part side of the handle part in L shape, T shape, etc. may be considered as the stepped part, or can be considered as the hooking part.

  Further, a groove that engages with the tip of the driver may be formed on the top of the handle. The groove portion is configured to allow the screw portion to be screwed into a tooth by engaging a small screwdriver or the like with the groove portion.

  The fall prevention device may be a flexible and bendable rod-shaped body. If this rod is passed between the thumb and forefinger, even if the thumb and index finger holding the fall prevention tool slide unintentionally and the tooth extraction tool may be removed, Since the rod-shaped body that has been passed between the thumb and the index finger reacts in a reflective manner, the extraction tool is less likely to be removed toward the throat.

  The anti-slip portion may be a concave portion or a convex portion formed on the surface of the handle portion. These concave portions and convex portions serve to improve grip performance. Further, the screw portion may be formed such that the thread pitch at the tip is smaller than the pitch of other portions. At the tip of the screw thread with a small pitch, a tooth is attached to the tooth, and at a portion with a larger pitch than this, the tooth is cut into the tooth efficiently and firmly. Further, a buffer portion may be provided at the top of the handle portion. For example, a silicon rubber hemisphere is used for the buffer portion. Thereby, even if the end of the handle portion hits meat in the oral cavity, it becomes safer.

  According to the tooth extraction tool of the present invention, it is possible to extract a tooth by simply digging it into the tooth hole and pulling it. Therefore, there is an effect that the treatment is safer and easier. The device provided with the fall prevention tool has an advantage that the extraction tool is rarely removed even if the hand slips.

2 is an explanatory diagram of Embodiment 1. FIG. FIG. 6 is an explanatory diagram of Example 2. 10 is an explanatory diagram of Example 3. FIG. It is explanatory drawing of Example 4. FIG.

  Hereinafter, four examples of the present invention will be described with reference to FIGS. 1 to 4, but the present invention is not limited to these examples.

  As shown in FIG. 1, the tooth extraction tool 1 of the present embodiment includes a screw portion 10 for screwing into a tooth and a handle portion 11, and a non-slip convex strip portion 12 is provided on the handle portion 11. It is. These screw portion 10 and handle portion 11 are provided via a shaft portion 13 as a rotation center axis, and a step portion 14 is formed between the shaft portion 13 and the handle portion 11. In this embodiment, the screw portion 10 is provided so as to bite into the tooth root by rotating clockwise. That is, the screw portion 10 is not for cutting but for screwing. Although the selection of the material of the screw portion 10 is arbitrary, a nickel-titanium alloy is used here. Moreover, regarding the anti-slip | skid part of the handle | steering-wheel part 11, you may make it a concave part instead of the convex part 12, or may mix a convex part and a concave part. Or you may make it arrange | position many round convex parts like milk in a bell.

  In this usage, the handle portion 11 is picked with the thumb, forefinger, and middle finger and inserted into the root canal of the decayed tooth, and the handle portion 11 is rotated clockwise as indicated by the arrow with the picked finger. At this time, since the handle portion 11 is provided with the non-slip ridge portion 12, the finger is less likely to slip due to saliva or the like. In this way, the screw portion 10 is firmly bitten into the root of the tooth. At this time, the tooth decay is lifted by the twist applied to the tooth decay. Then, if the handle portion 11 is then strongly picked with fingers or sandwiched between the jaws of the forceps and pulled in the direction of pulling out the teeth, the tooth is easily extracted. The non-slip ridge 12 is useful also in this case. This series of treatments is safe. Extraction is also possible by pulling teeth with a forceps or the like hung on the stepped portion 14.

  By the way, as described above, the screw portion 10 is firmly screwed into the root canal of the caries so as not to be easily removed. However, since broken teeth are easy to remove, this is not a problem.

  As shown in FIG. 2, the tooth extraction tool 2 of this embodiment is formed by connecting a screw portion 20 for screwing into a tooth and a handle portion 21 by a shaft portion 22 as a rotation center axis. The shaft portion 22 and the handle portion 21 have a T shape. A side portion of the T-shape is a step portion 23, and the T-shaped shaft portion 22 and the handle portion 21 are picked and used. This portion is exactly a non-slip portion. Further, a very flexible and flexible synthetic resin rod 24 is attached to the top of the handle portion 21.

  According to the tooth extraction tool 2 of the present embodiment, tooth extraction can be performed by a usage method such as a cork polar, so extraction is safe and easy. In addition, tooth extraction with a forceps or the like hung on the stepped portion 23 is possible.

  Further, the tooth extraction tool 2 of the present embodiment is provided with a very flexible and bendable rod-like body 24 at the top of the handle portion 21. The rod-like body 24 is passed between the thumb and the index finger or the middle finger when the handle portion 21 is picked with the thumb and the index finger or the middle finger and inserted into the root canal of the caries. Then, the rod-shaped body 24 passes through the circle formed by the thumb, forefinger, and middle finger and curves toward the palm, and the rod-shaped body 24 also rotates to the right as the screw portion 20 rotates to the right. The presence of 24 does not constitute a work resistance. In addition, even if the finger slips and unintentionally removes the extraction tool 2, the fingertip reacts reflexively and quickly grasps the rod-shaped body 24 that has been passed through the circle. Therefore, there is an effect that the removal of the tooth extraction tool 2 toward the throat is reduced.

  Next, the tooth extraction tool 3 of this embodiment shown in FIG. 3 includes a screw part 30 and a handle part 31 for screwing into the teeth. The handle part 31 is shaped like an umbrella handle. While having the stop part 32, the latching hole 33 is opened by the site | part which contact | wins the axial part in embodiment mentioned above. Both the latching portion 32 and the latching hole 33 are according to the invention of claim 3.

  When screwing out the tooth extraction tool 3 of this embodiment into the root canal of the caries, the shape of the handle part 31, the hook part 32 and the hook hole 33 play a role as an anti-slip part, and when pulling out the caries, the handle The part 31 can be picked with a finger, or can be used by putting forceps or the like on the latching part 32 or the latching hole 33.

  Now, the tooth extraction tool 4 of the present embodiment is shown in FIG. 4, which has a handle portion 41 having a non-slip convex portion 42 formed around it and a screw portion 40 to be screwed into the teeth. This is characterized in that a groove 43 is formed in the top portion of the handle portion 41. The non-slip convex portion 42 is composed of a lot of round convex portions such as milk on the bell. A rubber cap 44 made of silicon rubber as a buffering portion is provided on the top portion of the handle portion 41 excluding the groove portion 43, so that it is safer even if it hits the inner wall of the oral cavity. The groove 43 is fitted with a tip of a driver or a chuck such as a handpiece.

  When the extraction tool 4 of this embodiment is screwed into the root canal of the caries, a chuck such as a driver tip or a handpiece is put on the groove 43. As a result, the extraction tool 4 can be more easily screwed into the root canal.

Other embodiments

  In addition, it is desirable to prepare several sets of tooth extraction tools of the present invention having different thicknesses and lengths. The configuration of the handle portion and the screw portion is also arbitrary. For example, the screw portion may be formed by screwing around a cylindrical shape without forming a taper and sharpening the tip. Further, as an example of the anti-slip portion of the handle portion, a rubber coating having a concavo-convex pattern as seen on a shoe sole or tire can be raised on the surface provided around the handle portion. Also, two types of screws having different pitches may be screwed into the screw portion with the shorter pitch as the tip side. The reason why the pitch on the tip side is made smaller is to devise a way to stabilize the screwing work by improving the approach to the teeth when screwing the screw part into the root canal of the caries.

  Since the tooth extraction tool of the present invention can be used only with the fingertip of a dentist, this method of use makes it possible to extract a tooth safely and easily while reassuring a child. Therefore, the tooth extraction tool of the present invention can be provided for pets.
