ABSTRACT:
An endoscopic surgical instrument has an insertion portion to be inserted in a channel of an endoscope, a treatment portion provided at a tip of the insertion portion for treating an objective part and a manipulation portion provided close to a proximal end of the insertion portion. The operator can move the insertion portion forward and backward at least relative to the channel by operating the manipulation portion in a state the endoscopic surgical instrument is inserted in the channel of the endoscope. In this manner, by the manipulation portion, the endoscopic surgical instrument can be operated to move forward and backward relative to the channel. Therefore in case the manipulation portion is located close to a channel entrance (forceps port) of the endoscope, the operator of the endoscope is able to manipulate the endoscopic surgical instrument without assistance from others.
