On an inner circumference side of a stator fixed in an inner housing, a rotor is arranged. The rotor rotates through a bearing with respect to a center shaft that is a stationary shaft fixed to outer housings. Oil introduced into a rotor oil inlet path in the center shaft flows through a communication path and a clearance on an outer circumference of the center shaft into an oil path in the rotor. The oil flowing through the oil path cools a permanent magnet, lubricates the bearing, and is discharged from a rotor oil discharge port to the outside of the inner housing. The oil in the clearance is sealed with a thread seal, i.e., an inner thread formed in an inner face of an end ring and is prevented from flowing toward the bearing.

An acoustic matching device has a water bag () that contains water and a water bag support frame () that sandwiches and supports the water bag on the left and right sides of the knee and curves along the knee cap. The water bag becomes a plate shape curved along the shape of the water bag support frame, which touches the knee cap and fits the unevenness of the knee. When an ultrasonic probe is moved along the knee cap, the acoustic matching between the knee cap and the ultrasonic probe is obtained.

Knee acoustic matching device for ultrasonic probe

A mounting unit () is aligned by using a mounting unit frame () touching the thigh and a knee-contacting portion () touching the knee, with the knee being bent. The mounting unit is also equipped with a probe support frame () 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 () to move along the knee cap while facing toward the mechanical center of the knee joint and to perform scanning of an ultrasonic beam.
