Description

本発明は、歯科用口腔内観察装置、より詳細には、歯科治療において、口腔内や歯根内等の様子を撮影観察する歯科用口腔内観察装置に関する。   The present invention relates to a dental intraoral observation device, and more particularly, to a dental intraoral observation device that photographs and observes the state of the oral cavity, roots, and the like in dental treatment.

歯科治療においては、例えば、歯根を切削、成形、洗浄した後、該歯根内に詰め物をする等の治療を行うが、その場合、歯根内が的確に切削、成形されているか否かを観るために口腔内観察装置（スコープ）を使用する。   In dental treatment, for example, after cutting, shaping, and washing the tooth root, a treatment such as filling the tooth root is performed. In this case, in order to see whether or not the inside of the tooth root is accurately cut and shaped. Use an intraoral observation device (scope).

図２は、本発明が適用される歯科用口腔内観察装置の一例を説明するための要部概略構成図、図３は図２に示したハンドピース１０内の電気回路の詳細を説明するための概略構成図で、図中、１０はハンドピース、２０は画像信号処理装置、３０はディスプレイ、４０はハンドピース１０と画像信号処理装置２０とを結ぶケーブルで、ハンドピース１０の先端部（ヘッド部）１０ａには、ＣＣＤイメージセンサ１１及びＬＥＤ光源１２を有し、口腔内の被観察部位をＬＥＤ光源１２によって照明し、該ＬＥＤ光源１２によって照明された部位の状況をレンズ１３、フィルタ１４等を通してＣＣＤイメージセンサ１１によって撮影し、撮影した画像をハンドピース１０内に設けられたＣＣＵ１５により画像信号に変換し、ケーブル４０を通して画像信号処理装置２０に伝送し、該画像信号処理装置２０により画像処理し、ディスプレイ３０上に表示する。   FIG. 2 is a schematic configuration diagram of a main part for explaining an example of a dental intraoral observation apparatus to which the present invention is applied, and FIG. 3 is a diagram for explaining details of an electric circuit in the handpiece 10 shown in FIG. In the figure, 10 is a handpiece, 20 is an image signal processing device, 30 is a display, 40 is a cable connecting the handpiece 10 and the image signal processing device 20, and the tip of the handpiece 10 (head Part) 10a has a CCD image sensor 11 and an LED light source 12, and illuminates the observed region in the oral cavity with the LED light source 12, and the conditions of the region illuminated by the LED light source 12 are a lens 13, a filter 14, etc. Through the CCD image sensor 11, the photographed image is converted into an image signal by the CCU 15 provided in the handpiece 10, and passed through the cable 40. Transmitted to the image signal processing unit 20, and image processing by the image signal processing device 20, and displays on the display 30.

口腔内観察にあたって、術者は、まず、画像信号処理装置２０のメインスイッチ２１をオンし、その後、ハンドピース１０に設けられている操作ボタン１６を押すと、コントロール線１６ａ，１６ｂ間が接続（オン）され、画像信号処理装置２０は、この操作ボタン１６が押されたことを検知して、ＬＥＤ光源１２を点灯するとともに、ＣＣＵ１５を駆動し、ＣＣＤ１１によって撮像された画像をディスプレイ３０上に動画表示する。この状態で、操作ボタン１６を押すと、表示中の動画像がディスプレイ３０上に静止画表示され、ＣＣＵ１５の駆動が停止され、ＬＥＤ光源１２が消灯される。しかし、操作ボタン１６を押す時に、ハンドピース１０が手振れし、静止画に乱れが生じ、鮮明な映像を表示することができない。   In the intraoral observation, when the operator first turns on the main switch 21 of the image signal processing device 20 and then presses the operation button 16 provided on the handpiece 10, the control lines 16a and 16b are connected ( The image signal processing device 20 detects that the operation button 16 has been pressed, turns on the LED light source 12, drives the CCU 15, and displays an image captured by the CCD 11 on the display 30. indicate. When the operation button 16 is pressed in this state, the moving image being displayed is displayed as a still image on the display 30, the drive of the CCU 15 is stopped, and the LED light source 12 is turned off. However, when the operation button 16 is pressed, the handpiece 10 is shaken, the still image is disturbed, and a clear image cannot be displayed.

しかし、上述のごとき操作ボタン付ハンドピースを用いる歯科用口腔内観察カメラは、口腔内或いは歯根内の様子を正確に観察したい場合に、前記ハンドピースに設けられている操作ボタンを押し、動画像を静止画像にして観察するが、その際、操作ボタン１６をオンさせるために押し込みが必要となるため、オンの瞬間に手振れが生じ、ハンドピース（カメラ本体）１０が動いてしまい、ディスプレイ３０上の表示画面に乱れが生じて見えにくい等の不具合があった。   However, a dental intraoral observation camera using a handpiece with an operation button as described above, when it is desired to accurately observe the state in the oral cavity or root, presses the operation button provided on the handpiece, In this case, since it is necessary to push the operation button 16 to turn it on, the handpiece (camera body) 10 moves and the handpiece (camera main body) 10 moves and the display 30 is moved. The display screen was disturbed, making it difficult to see.

本発明は、上述のごとき実情に鑑みてなされたもので、前述の操作ボタンに代って、シート状の抵抗素子スイッチを用い、このシート状抵抗素子の上を軽く指で触れてスライドすることにより、動画像から静止画像に変換する際の手振れによる画像の乱れを防止することを目的としてなされたものである。   The present invention has been made in view of the above circumstances, and uses a sheet-like resistance element switch instead of the aforementioned operation button, and lightly touches and slides on the sheet-like resistance element with a finger. Thus, the purpose of the present invention is to prevent image distortion due to camera shake when converting a moving image to a still image.

請求項１の発明は、先端部にＣＣＤイメージセンサとＬＥＤ光源を、グリップ部にシート状抵抗素子スイッチを有し、該シート状抵抗素子スイッチ上を触れてスライドすることにより、前記ＬＥＤ光源をオン／オフし、前記ＣＣＤイメージセンサからの映像をディスプレイ上に表示し、前記ディスプレイ上に動画を表示中に、前記シート状抵抗素子スイッチ上を接触スライドすることにより、動画を静止画に切り換えるようにしたことを特徴としたものである。   The invention of claim 1 has a CCD image sensor and an LED light source at the tip, and a sheet-like resistance element switch at the grip, and the LED light source is turned on by sliding on the sheet-like resistance element switch. The video from the CCD image sensor is displayed on the display, and the moving image is switched to the still image by sliding on the sheet resistance switch while the moving image is displayed on the display. It is characterized by that.

請求項２の発明は、請求項１の発明において、前記スライドは、前記シート状抵抗素子上を軸方向又は周方向に接触スライドするものであることを特徴としたものである。   The invention of claim 2 is characterized in that, in the invention of claim 1, the slide slides in contact with the sheet resistance element in the axial direction or circumferential direction.

本発明によると、シート状の抵抗素子スイッチを用い、このシート状抵抗素子の上を軽く指で触れてスライドするようにしたので、動画像から静止画像に変換する際のスイッチ操作に手振れが生じず、静止画像に乱れが生じない。   According to the present invention, since a sheet-like resistor element switch is used and the sheet-like resistor element is lightly touched with a finger and slid, camera shake occurs in switch operation when converting from a moving image to a still image. Therefore, the still image is not disturbed.

図１は、本発明による歯科用口腔内観察装置の一実施例を説明するための図で、図１（Ａ）は本発明による操作スイッチを有するハンドピース１０の要部概観構成図で、図１（Ｂ）は図１（Ａ）に示したハンドピース１０の内部電気回路図で、図中、図２及び図３に示した従来の歯科用口腔内観察装置と同様の作用をする部分には図２及び図３の場合と同一の参照番号が付してある。而して、本発明は、図２及び図３に示した従来技術における操作ボタン１６に代って、シート状の抵抗素子スイッチ１７を用い、このシート状抵抗素子１７の上を軽く指で触れてスライドするようにすることにより、動画像から静止画像に変換する際の手振れによる画像の乱れを防止するようにしたものである。   FIG. 1 is a view for explaining an embodiment of a dental intraoral observation apparatus according to the present invention, and FIG. 1 (A) is a schematic view of the main part of a handpiece 10 having an operation switch according to the present invention. 1 (B) is an internal electrical circuit diagram of the handpiece 10 shown in FIG. 1 (A). In the figure, the portion that operates in the same manner as the conventional dental intraoral observation device shown in FIGS. Are denoted by the same reference numerals as in FIGS. Thus, in the present invention, instead of the operation button 16 in the prior art shown in FIGS. 2 and 3, a sheet-like resistance element switch 17 is used, and the sheet-like resistance element 17 is lightly touched with a finger. Thus, the image is prevented from being disturbed due to camera shake when the moving image is converted into the still image.

本発明によると、歯科用口腔内観察装置（口腔内カメラ，歯根内視鏡，キャナルスコープ）によると、例えば、ハンドピース１０のグリップ部又はグリップより先端側の表面に、シート状の抵抗素子スイッチ１７が貼られており、このシート状の抵抗素子１７の上に、術者の指を軽く載せて軸方向（前後方向）又は周方向（左右方向）にスライドすると、スライド量に従って抵抗値が変化し、接点１６ａ，１６ｂ間がオン，オフする。なお、スライド方向は、前述のように、軸方向，周方向のいずれでもよいが、周方向にすると、ハンドピースを握った状態での指の移動がより容易である。しかし、本発明は、スライド方向によって制限されるものではなく、任意所望の方向へスライドさせるようにしてもよい。   According to the present invention, according to a dental intraoral observation apparatus (intraoral camera, root endoscope, canal scope), for example, a sheet-like resistance element switch is provided on the surface of the handpiece 10 on the tip side from the grip part or grip. 17 is affixed, and when the operator's finger is lightly placed on the sheet-like resistance element 17 and slid in the axial direction (front-rear direction) or the circumferential direction (left-right direction), the resistance value changes according to the sliding amount The contacts 16a and 16b are turned on and off. As described above, the sliding direction may be either the axial direction or the circumferential direction. However, when the sliding direction is set to the circumferential direction, it is easier to move the finger while holding the handpiece. However, the present invention is not limited by the sliding direction, and may be slid in any desired direction.
