PROBLEM TO BE SOLVED: To provide a probe head of a ultrasonic diagnostic apparatus having a shape that is easy to hold and operate.SOLUTION: A grip section 14 of the probe head 10, which is a part to be held by an operator, has a stepped shape with a large diameter section 18 and a small diameter section 20. The small diameter section 20 has a flange section 24 on the proximal side and is tapered toward the distal section from the flange section. The probe head is prevented from being dropped by gripping the small diameter section by the thumb, the index finger and the middle finger and thus gripping the flange section 24 and the tapered section extending from the flange section by the thumb and the index finger. In addition, force to press the probe head to the subject is easily transmitted to the head by pressing a shoulder section 22 formed by a step at a boundary between the large diameter section and the small diameter section with the middle finger and the thenar.COPYRIGHT: (C)2011,JPO&INPIT【課題】超音波診断装置の探触子ヘッドの形状を保持しやすく、また操作しやすいものとする。【解決手段】探触子ヘッド10は、操作者が保持する部分である握り部14が、大径部18と小径部20を有する段付き形状である。小径部20の基端側には、つば部24が設けられ、ここから先端に向けて先細の形状となっている。小径部を母指、示指、中指により握ると、つば部24およびこれに続く先細形状の部分が、母指および示指により握られ探触子ヘッドを落としにくくなる。また、大径部と小径部の境の段差で形成される肩部22を中指、母指球で押すようにでき、探触子ヘッドを被検体に押圧する力を容易にヘッドに伝達することができる。【選択図】図1
