Ultrasound diagnosis apparatus with a probe and a grounding switch feature

1. An ultrasound probe comprising:

a plurality of piezoelectric vibrators configured to

generate ultrasound waves,

receive reflection waves, and

generate a reception signal based on the received reflection waves for generating an ultrasonic image;

a switching board; and

a connecting mechanism configured to switch via an actuating mechanism between a short state in which an electrode of the plurality of piezoelectric vibrators is connected to a ground (GND) terminal on the switching board and an open state in which the electrode of the plurality of piezoelectric vibrators is not connected to the GND terminal on the switching board,

wherein the connecting mechanism switches all of the plurality of piezoelectric vibrators to the open state at a timing when the connection between the ultrasound probe and an apparatus main body that generates the ultrasonic image based on the reception signal is in a locked state, and switches all of the plurality of piezoelectric vibrators to the short state at a timing when the connection between the ultrasound probe and the apparatus main body is in an unlocked state.

2. The ultrasound probe according to claim 1 , wherein the connecting mechanism is configured to switch between the short state and the open state by electrical control, based on a condition of connection between the ultrasound probe and the apparatus main body.

3. The ultrasound probe according to claim 1 , wherein the connecting mechanism is configured to switch between the short state and the open state in accordance with a change of an arrangement position, based on a condition of connection between the ultrasound probe and the apparatus main body.

4. The ultrasound probe according to claim 2 , wherein the connecting mechanism is configured to switch between the short state and the open state by an actuator that uses an electromagnetic force.

5. The ultrasound probe according to claim 3 , wherein the switching board is interlocked with a handle or a knob or a switch for connecting the ultrasound probe to the apparatus main body and switches between the short state and the open state.

6. The ultrasound probe according to claim 1 , wherein the connecting mechanism is configured to switch between the short state and the open state at a timing of accepting an input operation from an operator.

7. The ultrasound probe according to claim 1 , wherein the connecting mechanism is configured to switch between the short state and the open state at a predetermined timing.

8. An ultrasound diagnosis apparatus comprising:

an ultrasound probe; and

an apparatus main body that generates an ultrasonic image based on a reception signal generated by the ultrasound probe,

wherein the ultrasound probe includes

plurality of piezoelectric vibrators configured to

generate ultrasonic waves,

receive reflection waves, and

generate the reception signal based on the received reflection waves for generating the ultrasonic image, and

a switching board; and

a connecting mechanism configured to switch via an actuating mechanism between a short state in which an electrode of the plurality of piezoelectric vibrators is connected to a ground (GND) terminal on the switching board and an open state in which the electrode of the plurality of piezoelectric vibrators is not connected to the GND terminal on the switching board,

wherein the connecting mechanism switches all of the plurality of piezoelectric vibrators to the open state at a timing when the connection between the ultrasound probe and an apparatus main body that generates the ultrasonic image based on the reception signal is in a locked state, and switches all of the plurality of piezoelectric vibrators to the short state at a timing when the connection between the ultrasound probe and the apparatus main body is in an unlocked state.
