PURPOSE:To provide an intra-celom ultrasonic probe featuring flexibility, torque transmittability, strength and formation to a smaller diameter. CONSTITUTION:A hollow coil 2 contg. a signal line and driving shaft 7 is coated with a braiding 3. This braiding 3 is coated with a coating part 4 sealed at the front end or a coating part 4 having an aperture at the front end. The front end of the driving shaft is provided with an ultrasonic vibrator transducer 6. As a result, the flexibility, torque transmittability, the strength and the formation to a smaller diameter are attained. |
