The present invention provides an improved ultrasound probe. By using the ultrasound probe, the surgeon can detect the target areas more precisely during surgery. The ultrasound transducer comprises a body and an engaging element. The body contacts the skin of patient by using its one end and a groove. The groove disposed on its one side surface of the body and extended towards the end contacting the skin of the patient. The engaging element is adjacent to the groove of the body may be located between a first position and a second position with respect to the groove. When the engaging element is located at the first position, the object can be engaged in the groove. When the engaging element is located at the second position, the object can be separated from the groove.本發明提供一種改良的超音波探頭,係以一超音波換能器為本體,經改良後可以增進在患者手術目標區域的準確定位。上述超音波探頭至少包含該本體與一卡合件,該本體以其一端接觸患者之皮膚,且一側面開設有由可接觸患者之皮膚一端所延伸之一凹槽,而該卡合件係鄰設於本體之凹槽,得使一物件側面分離或卡合於凹槽中,且卡合件相對於凹槽位於一第一位置與一第二位置;其中,當卡合件相對於凹槽位於第一位置時,物件係卡合於凹槽中,反之,當卡合件相對於凹槽位於第二位置時,物件係與本體側面分離。100‧‧‧超音波探頭10‧‧‧本體11‧‧‧凹槽12‧‧‧超音波發射/接收區20‧‧‧卡合件S‧‧‧皮膚T‧‧‧目標區域D1‧‧‧凹槽之延伸方向
