摘要 |
An ultrasound transmission medium feed device particularly for an endoscopically inserting ultrasound probe adapted to be introduced into a body cavity through and under the guidance of one of biopsy channels provided on an endoscope. The ultrasound transmission medium feed device essentially comprises: a balloon fitted on a base end portion of an ultrasound scanner head fixedly in a hermetically sealed state in such a way as to wrap in an end housing of the scanner head; a fluid inlet-outlet passage provided on the base end portion of the ultrasound scanner head for charging and discharging an ultrasound transmission medium into and out of the balloon through a communicating port; and a pressurizing feed tube adapted to be placed in another biopsy channel of the endoscope and disconnectibly connectible at a fore distal end portion thereof with the fluid inlet-outlet passage on the ultrasound scanner head, the pressurizing feed tube having a pressurizing member in association with a proximal end portion thereof for pressurizing or depressurizing the ultrasound transmission medium to be supplied to the inlet-outlet passage on the ultrasound scanner head of the probe.
