Patent ID: 7347860

Claim:
An endoscope for high-frequency treatment, comprising: a flexible inserting section adapted to be inserted in a human cavity; an operation unit connected to a proximal end of the flexible inserting section, at least one terminal, which is connected to a high-frequency power supply, being provided to the operation unit; a hood provided with at least one treatment electrode for the high-frequency treatment, at least one contact and at least one conductive line connecting the at least one treatment electrode and the at least one contact; and a tip unit provided at a tip end of the inserting section, the tip unit being formed with a hood receiving portion to which the hood is detachably couples, the tip unit being provided with at least one resiliently deformable power supply electrode which contacts the at least one contact of the hood when the hood is coupled to the tip unit and is resiliently biased by the at least one contact to retain the hood in position, the at least one power supply electrode being connected with the at least one terminal provided to the operation unit through a conductive wire which is inserted in the inserting section.
