the present invention, a constant length of the tube, the tube as both ends are exposed to the outside deformable cylinder and which is installed to be fitted in is formed in a hollow shape, and a length of the guide needle is arranged so as to overlay covers the outer periphery of the tube and is connected with an end of the tube, In response to the transmission of power from the outside or to position the tube in the radial direction, or the direction controller to vibrate, the vibration generating section which receives the transmission of power from the outside to vibrate along said cylinder in the axial direction, and is coupled with the end of the tube, there is provided a diagnostic probe comprising a handle portion connected to the vibration generating portion and the direction controller. The present invention also provides an inspection apparatus having the diagnostic probe.本発明は、一定の長さのチューブと、両端が外部に露出するように前記チューブに嵌まって設置される変形可能なシリンダーと、中空形状に形成され、前記チューブの外周部を覆いかぶせるように配置される一定の長さのガイドニードルと、前記チューブの端部と連結され、外部から動力の伝達を受けて前記チューブを半径方向に沿って位置させるか、または振動させる方向制御部と、外部から動力の伝達を受けて前記シリンダーを軸方向に沿って振動させる振動発生部、及び前記チューブの端部と連結され、前記方向制御部と前記振動発生部と連結される取手部を含む診断用プローブを提供する。また、本発明は前記診断用プローブを有する検査装置も提供する。
