PROBLEM TO BE SOLVED: To provide an ultrasonic treatment device capable of shortening operating time even when excision/hemostasis is performed at a plurality of locations.SOLUTION: The ultrasonic treatment device is provided with: a probe which is inserted into a sheath and a treatment section which is linked to or formed as a single unit with the tip end section of the probe and is exposed outside of the sheath. The ultrasonic treatment device, which transmits ultrasonic waves to the treatment section by way of the probe to excise or clot an affected area, is provided with a mechanism for cooling the treatment section by subjecting the probe to heat exchange with a cooling gas that is discharged into the sheath.COPYRIGHT: (C)2012,JPO&INPIT【課題】複数部位の切除・止血を行う場合にあっても手術時間を短縮することができる超音波治療装置を提供する。【解決手段】超音波治療装置は、シースに内挿されたプローブと、プローブ先端部に連結もしくは一体形成された、シース外部に露出した処置部と、を備え、プローブを介して処置部に超音波を伝播させて患部を切除するもしくは凝固させる超音波治療装置であって、シース内に吐出させた冷却ガスとプローブで熱交換を行うことで処置部を冷却する機構を備えたことを特徴とする。【選択図】図1
