PROBLEM TO BE SOLVED: To easily puncture an intended region with an injection needle under ultrasonic observation.SOLUTION: An injection needle puncture guide includes: an alignment guide part for aligning a target axis as an arrival target of an injection needle with a scanning surface of a probe of an ultrasonic diagnostic apparatus for observing a sectional view of the interior of a living body by scanning with ultrasonic waves an in-plane movement limiting part provided with an injection needle insertion space in which the injection needle can be inserted, which limits the movement of the injection needle inserted in the injection needle insertion space so that the injection needle goes along the orthogonal plane containing the target axis a reference point guide part for guiding the injection needle to pass through the reference point in the orthogonal plane an injection needle angle adjusting part for adjusting the angle of the injection needle in passing through the reference point an approach length limiting part for limiting the movement of the injection needle so that the tip of the injection needle does not exceed the target axis according to the angle adjusted by the injection needle angle adjusting part and a depth graduation part for displaying the depth of the tip from the surface of the skin, as well as the angle adjustable by the injection needle angle adjusting part at the time of the tip of the injection needle arriving at the target axis.COPYRIGHT: (C)2014,JPO&INPIT【課題】超音波観測下で目的の部位に注射針を穿刺しやすくする。【解決手段】超音波を走査して生体内部の断面図を観測する超音波診断装置の探触子の走査面に、前記注射針の到達目標である目標軸を合わせるための位置合わせガイド部と、注射針を挿入可能な注射針挿入空間が形成され、該目標軸を含む直交平面に該注射針が沿うように、該注射針挿入空間に挿入された該注射針の移動を制限する平面内移動制限部と、該直交平面内の基準点を通るように該注射針を案内する基準点ガイド部と、該基準点を通る際の該注射針の角度を調整する注射針角度調整部と、該注射針角度調整部によって調整された角度に応じて、該注射針の先端が該目標軸を超えないように、該注射針の移動を制限する進入長制限部と、該注射針の先端が該目標軸に到達した場合における、該先端の皮膚表面からの深度を、該注射針角度調整部による調整可能な角度とともに表示する深度目盛部とを備えた。【選択図】図1
