Abstract

The balloon dismounting tool includes: a cylindrical holding part (51); a groove (51m) for locking the balloon tape falling off from the outer periphery (30g) of the ultrasonic vibrator unit (30); a cutting part (S) for Cutting the holding part (51) from one end (51p) to the other end (51q); the fitting part (60), which makes the inner peripheral surface (51n) of the holding part (51) from the other end (51q) toward one end (51p ) is reduced in diameter and the fitting portion (60) is formed by a member that can expand in diameter in the radial direction (K); The inner side protrudes and abuts against one end of the fitting portion (60).

Description

technical field [0001] The present invention relates to a balloon removal tool for removing a balloon from the outer periphery of an ultrasonic vibrator unit at the tip of an insertion portion of an ultrasonic endoscope. Background technique [0002] Ultrasound endoscopes are known that obtain ultrasound images of a site to be examined by transmitting and receiving ultrasonic waves from an ultrasound transducer inside an ultrasound transducer unit provided at the distal end of an insertion portion to and from the site to be examined. [0003] Also known is a configuration in which a balloon is attached to the outer periphery of the ultrasonic transducer unit in order to efficiently transmit and receive ultrasonic waves to the site to be examined and to maintain the ultrasonic transducer unit at an appropriate distance from the site to be examined. In addition, an ultrasonic transmission medium such as deaerated water is sealed in the balloon. [0004] In addition, the ballo...
