PROBLEM TO BE SOLVED: To provide a wireless type ultrasound probe, enabling stable ultrasound diagnosis with a puncture technique.SOLUTION: In the top face of a puncture guide 2 integrated with a probe body 1, weights W are buried in a direction orthogonal to the direction of arrangement of a transducer array on both sides of the transducer array. When the ultrasound transmission/reception surface of the transducer array is set horizontal, the position of the center of gravity G is located between the center of arrangement of the transducer array and the puncture needle insertion port 8 of the puncture guide in the direction of arrangement of the transducer array, also located substantially on the centerline of arrangement of the transducer array in the direction orthogonal to the direction of arrangement of the transducer array, and located below the height H/2, which is half of the height H of a casing 3.COPYRIGHT: (C)2012,JPO&INPIT【課題】穿刺手技を伴う超音波診断を安定して行うことができる無線式の超音波プローブを提供することを目的とする。【解決手段】プローブ本体1に一体化された穿刺ガイド2の上面には、振動子アレイの配列方向に対して直交する方向で且つ振動子アレイの両側にそれぞれ重りWが埋設され、振動子アレイの超音波送受信面を水平にしたときの重心Gの位置が、振動子アレイの配列方向に関して振動子アレイの配列の中心と穿刺ガイド2の穿刺針挿入口8との間に存在し且つ振動子アレイの配列方向に直交する方向に関して振動子アレイの配列のほぼ中心線上に存在し、また、筐体3の高さHの1/2の高さH/2より下方に存在する。【選択図】図1
