Description
本考案は、医療用品に関し、更に詳しくは、歯科用ツールの延長部材に関する。 The present invention relates to a medical article, and more particularly to an extension member of a dental tool.
歯科治療分野において、歯科医師は所定の治療を行う際に、患者の口腔中に入れる各種類のツールを使用することが一般的である。例えば、図１を示すように、従来の歯科用ツール５０の多くは、加工ヘッド部５１とシャンク５２とを有するものである。治療をする場合、歯科医師は前記歯科用ツール５０のシャンク５２を手で持って、前記加工ヘッド部５１を患者の口腔中に入れながら治療を行うことができる。 In the field of dental treatment, a dentist generally uses various types of tools that are placed in the patient's mouth when performing a predetermined treatment. For example, as shown in FIG. 1, many of the conventional dental tools 50 have a processing head portion 51 and a shank 52. In the case of treatment, the dentist can hold the shank 52 of the dental tool 50 by hand and perform the treatment while placing the processing head portion 51 in the patient's mouth.
従来の歯科用ツールは一定の長さを有するものである。この従来の歯科用ツールを操作して前側の歯（例えば、前歯）の治療を行う場合には、その操作に大きな妨害が引き起こす問題がないと考えられるが、前記従来の歯科用ツールを操作して後側の歯（例えば、臼歯）を治療する場合には、当該歯の治療ができなくなってしまうという重大な問題が引き起こされることある。 Conventional dental tools have a certain length. When this conventional dental tool is operated to treat the front teeth (for example, the front teeth), it is considered that there is no problem that the operation is greatly disturbed, but the conventional dental tool is operated. In the case of treating a rear tooth (for example, a molar), a serious problem that the treatment of the tooth cannot be performed may be caused.
例えば、後側の歯（例えば、臼歯）を治療する場合は、歯科用ツールを口腔の深くまで進入させなければならないため、加工ヘッド部の一部分が口腔内に入ってしまうことがある。 For example, when treating the rear teeth (for example, molars), a dental tool must be advanced deep into the oral cavity, so that a portion of the processing head portion may enter the oral cavity.
また、後側の歯を治療する際に、歯科用ツールを握る歯科医師の手が患者の口腔に非常に接近するか接触することにより、患者の口が病原菌の感染を引き起こす可能性があるほか、治療の進行に悪影響が及んだり、治療が困難になったり、ひいては、治療が失敗するとなってしまう最悪の可能性もある。 In addition, when treating the posterior teeth, the patient's mouth may cause infection by pathogens when the dentist's hand holding the dental tool is very close to or in contact with the patient's mouth. There is also the worst possibility that the progress of the treatment will be adversely affected, the treatment will be difficult, and the treatment will fail.
そこで、本考案者は前記の欠点が改善可能と考え、鋭意検討を重ねた結果、合理的設計で前記の課題を効果的に改善する本考案の提案に到った。 Therefore, the present inventor considered that the above-mentioned drawbacks can be improved, and as a result of intensive studies, the present inventors have arrived at a proposal of the present invention that effectively improves the above-described problems with rational design.

When the hand-held portion 20 is rotated to the opposite side and the tightening displacement member 32 is moved to the loosened position side, the two elastic tightening portions 323 are gradually separated from the head portion 311 to the inside. The handheld portion 20 is allowed to slide freely.
これにより、歯科医師は、先ず手持ち部２０を回転させて締め付け変位部材３２を前記緩め位置側に移動させ、その後に手持ち部２０を所定の位置まで滑動させ、前記歯科用ツールを適度な長さにする。この後、手持ち部２０が前述とは反対側に回転されたときには、締め付け変位部材３２が前記締め位置側に移動され、該締め付け変位部材３２が前記締め位置まで移動されて、手持ち部２０が回転できなくなったときには、手持ち部２０が前記締め位置に堅固に固定され、歯科医師が治療を行いやすくなる。歯科医師は手持ち部２０を最長の長さになるように滑動させ、後ろの歯の治療を行いやすくする（図６参照）。 Thereby, the dentist first rotates the hand-held portion 20 to move the tightening displacement member 32 to the loosened position side, and then slides the hand-held portion 20 to a predetermined position, so that the dental tool has an appropriate length. To. Thereafter, when the hand-held portion 20 is rotated to the opposite side, the tightening displacement member 32 is moved to the tightening position side, the tightening displacement member 32 is moved to the tightening position, and the hand-held portion 20 is rotated. When it becomes impossible, the hand-held part 20 is firmly fixed to the said tightening position, and it becomes easy for a dentist to perform a treatment. The dentist slides the hand-held part 20 so as to have the longest length, and makes it easy to treat the back teeth (see FIG. 6).
また、手持ち部２０は、ストッパー部２２を有し、ツール本体１０は、加工ヘッド部１１及びシャンク１２の交接箇所に当接部１５を有する。手持ち部２０が前記第一位置まで滑動されたときには、当接部１５がストッパー部２２に当接して、手持ち部２０は滑動を続けられなくなる（図４参照）。手持ち部２０が前記第二位置まで滑動されたときには、締め付け変位部材３２がストッパー部２２に当接して、手持ち部２０は滑動を続けられなくなる（図５参照）。 The hand-held portion 20 has a stopper portion 22, and the tool main body 10 has an abutting portion 15 at the intersection of the machining head portion 11 and the shank 12. When the hand-held part 20 is slid to the first position, the contact part 15 comes into contact with the stopper part 22 and the hand-held part 20 cannot continue to slide (see FIG. 4). When the hand-held portion 20 is slid to the second position, the tightening displacement member 32 comes into contact with the stopper portion 22, and the hand-held portion 20 cannot continue to slide (see FIG. 5).
結論として、本考案に係る歯科用ツールの延長部材によれば、歯科医師が自分でツールの長さを調整することが可能になる。伸長される場合には、構造のアームが長くなり、省力及び患者の口腔内部に深く進入できる効果を達成させる上、治療が行いやすくなる。また、短縮される場合には、使用者が収納及び消毒をしやすくなる。本考案に係る歯科用ツールの延長部材は、構造が簡単であり、堅牢性が高くなるため、商業的な競争力を有する。 In conclusion, the extension member of the dental tool according to the present invention enables the dentist to adjust the length of the tool himself.
