Abstract

An ultrasound probe comprises: a transducer array having an ultrasound transmission/reception surface; a housing for containing a transducer array, a transmission/reception board, a wireless communication board and a battery; and a puncture guide fixed to the housing and having a puncture needle insertion port located on a line extending in a direction of arrangement of the transducer array, wherein when the ultrasound transmission/reception surface of the transducer array is in a horizontal posture, the probe has a center of gravity lying between a center of arrangement of the transducer array and the puncture needle insertion port of the puncture guide in the direction of arrangement of the transducer array and, at the same time, being almost in accordance with a centerline of arrangement of the transducer array in a direction orthogonal to the direction of arrangement of the transducer array.

Claims

1. An ultrasound probe, comprising:

a transducer array having an ultrasound transmission/reception surface;

a transmission/reception board including a transmission/reception circuit for the transducer array;

a wireless communication board having a wireless communication circuit mounted thereon for wireless communication with an external communication device;

a battery for supplying power to the transmission/reception circuit and the wireless communication circuit;

a housing for containing the transducer array, the transmission/reception board, the wireless communication board and the battery; and

a puncture guide fixed to the housing and having a puncture needle insertion port located on a line extending in a direction of arrangement of the transducer array,

wherein when the ultrasound transmission/reception surface of the transducer array is in a horizontal posture, the probe has a center of gravity lying between a center of arrangement of the transducer array and the puncture needle insertion port of the puncture guide in the direction of arrangement of the transducer array and, at the same time, being almost in accordance with a centerline of arrangement of the transducer array in a direction orthogonal to the direction of arrangement of the transducer array.

2. The ultrasound probe according to claim 1, further comprising a plurality of weights mounted on the puncture guide so that they may be located on both sides of the transducer array in the direction orthogonal to the direction of arrangement of the transducer array.

3. The ultrasound probe according to claim 2, wherein the weights are each mounted on the puncture guide in a detachable manner.

4. The ultrasound probe according to claim 1, wherein the battery is positioned on the centerline of arrangement of the transducer array.

5. The ultrasound probe according to claim 1, wherein the battery is positioned away from the centerline of arrangement of the transducer array in the direction of arrangement of the transducer array.

6. The ultrasound probe according to claim 5, wherein the weights are positioned opposite to the battery with respect to the centerline of arrangement of the transducer array.

7. The ultrasound probe according to claim 1, wherein the center of gravity is at a height under one half a height of the housing when the ultrasound transmission/reception surface of the transducer array is in a horizontal posture.

8. The ultrasound probe according to claim 1, wherein the puncture guide is detachable from the housing.

9. An ultrasound probe, comprising:

a transducer array having an ultrasound transmission/reception surface;

a transmission/reception board including a transmission/reception circuit for the transducer array;

a wireless communication board having a wireless communication circuit mounted thereon for wireless communication with an external communication device;

a battery for supplying power to the transmission/reception circuit and the wireless communication circuit;

a housing for containing the transducer array, the transmission/reception board, the wireless communication board and the battery; and

a pressure plate fixed to the housing and having a pressure face almost flush with the ultrasound transmission/reception surface of the transducer array,

wherein when the ultrasound transmission/reception surface of the transducer array is in a horizontal posture, the probe has a center of gravity almost in accordance with a centerline of arrangement of the transducer array in both a direction of arrangement of the transducer array and a direction orthogonal to the direction of arrangement of the transducer array.

10. The ultrasound probe according to claim 9, further comprising a plurality of weights mounted on the pressure plate so that they may be located on both sides of the transducer array in the direction orthogonal to the direction of arrangement of the transducer array.

11. The ultrasound probe according to claim 9, wherein the weights are each mounted on the pressure plate in a detachable manner.

12. The ultrasound probe according to claim 9, wherein the battery is positioned on the centerline of arrangement of the transducer array.

13. The ultrasound probe according to claim 9, wherein the battery is positioned away from the centerline of arrangement of the transducer array in the direction of arrangement of the transducer array.

14. The ultrasound probe according to claim 13, wherein the weights are positioned opposite to the battery with respect to the centerline of arrangement of the transducer array.

15. The ultrasound probe according to claim 9, wherein the center of gravity is at a height under one half a height of the housing when the ultrasound transmission/reception surface of the transducer array is in a horizontal posture.

16. The ultrasound probe according to claim 9, further comprising a plurality of pressure sensors mounted on the pressure plate so that they may be located on both sides of the transducer array in the direction orthogonal to the direction of arrangement of the transducer array.

17. The ultrasound probe according to claim 9, wherein the pressure plate is detachable from the housing.
