PROBLEM TO BE SOLVED: To provide an ultrasound probe having a cut part, which ultrasound probe minimizes the influence of an ineffective part for preventing the degradation of luminance in an ultrasonographic image to thereby maintain the consistency of image quality, and which also position a puncture needle at the center of the scan face to thereby ensure the visibility of the puncture needle.SOLUTION: A puncture guide adapter in the embodiment comprises a base part, a guide part, and a fixing part. The base part is formed to continue to the scan face in the cut part of the ultrasound probe, and located at a position opposing a surface configured in parallel with an ultrasound transmission direction. The guide part is located at a position opposing the base part to let the puncture needle through between the guide part and the base part. The fixing part couples the base part and the guide part for fixing to the ultrasound probe. The base part is also formed to have a slope that inclines toward the focal point of the ultrasound.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】切欠部を備える超音波プローブにおいて、無効部の影響を最小限にして超音波画像における輝度低下を防止することで画質の均一性を維持しつつ、穿刺針をスキャン面の中心部に位置させて穿刺針の視認性を確保すること。【解決手段】実施の形態における穿刺ガイドアダプタは、基部と、ガイド部と、固定部とを備える。基部は、超音波プローブの切欠部のうち、スキャン面に連続して形成され、超音波の送信方向と平行に構成される面と対向する位置に配置される。ガイド部は、基部と対向する位置に配置され、基部との間に穿刺針を通す。固定部は、基部とガイド部とを連結し、超音波プローブに固定する。また、基部は、超音波の焦点に向けて傾斜するように傾きをもって形成される。【選択図】図４
