ULTRASOUND PROBE
An ultrasound probe includes an ultrasound transmission/reception portion which transmits and receives ultrasound, a proximal-end-side balloon fixing portion arranged on a more proximal end side than the ultrasound transmission/reception portion and having a stepped shape in which a proximal end side is high, and a balloon fixing tool mounting groove arranged on a more distal end side than the proximal-end-side balloon fixing portion and having a width narrower than a width of the proximal-end-side balloon fixing portion.
1 . An ultrasound probe comprising:
an ultrasound transmission/reception portion which transmits and receives ultrasound;
a proximal-end-side balloon fixing portion disposed on a more proximal end side than the ultrasound transmission/reception portion and having a stepped shape in which a proximal end side is high; and
a balloon fixing tool mounting groove arranged on a more distal end side than the proximal-end-side balloon fixing portion and having a width narrower than a width of the proximal-end-side balloon fixing portion.
2 . The ultrasound probe according to claim 1 , further comprising:
a balloon fixing tool formed so as to be attachable to and detachable from an outer circumference on a proximal end side of an ultrasound balloon, the balloon fixing tool being configured to fix the ultrasound balloon by pressing a part of the ultrasound balloon arranged so as to cover the ultrasound transmission/reception portion.
3 . The ultrasound probe according to claim 2 , wherein the balloon fixing tool is formed in a shape formed by cutting out a part of a circular ring shape.
4 . The ultrasound probe according to claim 2 , wherein the balloon fixing tool includes an identification portion configured to be able to identify the ultrasound probe to which the ultrasound balloon is fixed.
5 . The ultrasound probe according to claim 2 , further comprising a pressing portion which is disposed on a more distal end side than the proximal-end-side balloon fixing portion, configured to be advanceable and retractable on the more distal end side than the proximal-end-side balloon fixing portion, and fixes the ultrasound balloon by pressing a part of the outer circumference on a proximal end side of the ultrasound balloon.
