Abstract
An ultrasound probe includes: a first arm that swings along with rotation of a motor and includes a protrusion; a second arm that rotates along with rotation of a second gear engaged with a first gear attached to a first rotational shaft; a third arm attached to the second arm such that the third arm is rotatable with respect to the second arm; and an ultrasound device connected with the third arm. The protrusion of the first arm is connected with the third arm such that the protrusion is slidable on the third arm along the longitudinal direction of the third arm.
Claims22
An ultrasound probe comprising:
- a probe casing in which acoustic coupling liquid is sealed;
- a motor fixed to the probe casing;
- a first arm fixed to a first rotational shaft, and configured to rotate along with rotation of the first rotational shaft;
- a protrusion provided to the first arm;
- a first rotation transmission section attached to the first rotational shaft;
- a second rotation transmission section engaged with the first rotation transmission section, and configured to rotate when the first rotation transmission section rotates in a direction opposite to a direction in which the first rotation transmission section rotates;
- a second rotational shaft fixed to the second rotation transmission section, and configured to serve as a rotational shaft of the second rotation transmission section;
- a second arm fixed to the second rotational shaft, and configured to rotate along with rotation of the second rotational shaft;
- a third arm attached to the second arm such that the third arm is rotatable with respect to the second arm;
- and
- an ultrasound device connected with the third arm, wherein:
- the first arm, the second arm and the third arm are located in the probe casing;
- the motor is connected with the first rotational shaft or the second rotational shaft;
- the first rotational shaft or the second rotational shaft connected with the motor rotates along with rotation of the motor;
- and
- the protrusion provided to the first arm is connected with the third arm such that the protrusion provided to the first arm is slidable along a longitudinal direction of the third arm.
