Ultrasonic probe support device
View Patent ↗A mounting unit ( 16 ) is aligned by using a mounting unit frame ( 58 ) touching the thigh and a knee-contacting portion ( 62 ) touching the knee, with the knee being bent. The mounting unit is also equipped with a probe support frame ( 60 ) used for moving an ultrasonic probe along the knee cap. The probe support frame moves rotationally about the mechanical center of the knee joint, thereby allowing the ultrasonic probe ( 78 ) to move along the knee cap while facing toward the mechanical center of the knee joint and to perform scanning of an ultrasonic beam.
1. An ultrasonic probe support device which supports, in a state where a knee is bent, an ultrasonic probe in a movable manner along a knee cap, the ultrasonic probe support device comprising:
a mounting unit which is mounted on a thigh and a knee, wherein
the mounting unit comprises:
a mounting unit frame which contacts the thigh;
a knee-contacting portion which contacts the knee or a region below the knee; and
a probe support frame which supports the ultrasonic probe with respect to the mounting unit frame, and which supports the ultrasonic probe such that the ultrasonic probe moves along the knee cap in a state where the ultrasonic probe is directed toward a center of a knee joint.
2. The ultrasonic probe support device according to claim 1 , wherein
the knee-contacting portion comprises an acoustic matching member which is in contact with the knee cap and which realizes acoustic matching of transmitted and received ultrasound, and the acoustic matching member has a shape curved along the knee cap.
3. The ultrasonic probe support device according to claim 2 , wherein
the knee-contacting portion comprises a matching member support frame which is fixed on the mounting unit frame and which supports the acoustic matching member at a right side and a left side of the knee, and the matching member support frame has a shape curved along the knee cap, and
the acoustic matching member is set in the curved shape according to the curved shape of the matching member support frame.
4. The ultrasonic probe support device according to claim 1 , wherein
the matching member comprises a fixed portion which is supported on a matching member support frame, and a free portion which extends from the fixed portion and which is allowed to move in a front and rear direction.
5. The ultrasonic probe support device according to claim 3 , wherein
the matching member support frame has an arc shape.
6. The ultrasonic probe support device according to claim 4 , wherein
the matching member support frame has an arc shape.
7. The ultrasonic probe support device according to claim 1 , wherein
the probe support frame is rotatably supported with respect to the mounting unit frame, and the movement of the ultrasonic probe along the knee cap is realized by a rotation of the probe support frame.
8. The ultrasonic probe support device according to claim 1 , further comprising:
a base which is placed on a floor; and
a rotational frame which is provided on the base in a standing manner and which is rotatably supported on the base, wherein
the mounting unit is rotatably supported on the rotational frame, and
the rotational frame is rotated in a manner to be tilted toward the knee, and the mounting unit is contacted with the thigh and knee or a region below the knee.
9. The ultrasonic probe support device according to claim 8 , wherein
the rotational frame comprises:
a lower frame which is rotatably supported on the base; and
an upper frame which slides, with respect to the lower frame, in a radial direction of the rotation, and which rotatably supports the mounting unit.
10. An ultrasound diagnosis apparatus comprising the ultrasonic probe support device according to claim 1 and an ultrasound unit having an ultrasonic probe which is supported by the ultrasonic probe support device, wherein ultrasound information of cartilage at a distal end of a femur is obtained based on ultrasound transmitted and received by the ultrasonic probe.
