Patent ID: 7775970

Claim:
A cutting device for an endoscope comprising: an elongated outer tube member through which an endoscope is to be inserted and including a distal end portion where a distal end portion of the endoscope is to be arranged and a proximal end portion where a proximal end portion of the endoscope is to be arranged; a cutting member inserted through the outer tube member, including a cutting portion arranged at the distal end portion of the outer tube member and to perform a cutting, and configured to move so that the cutting member moves the cutting portion between a cutting position where the cutting portion is to perform the cutting and a standby position where the cutting portion is to perform no cutting through a switching position between the cutting position and the standby position; an operating portion to move the cutting member; a wipe member inserted through the outer tube member, including a wipe portion arranged at the distal end portion of the outer tube member, and configured to move so that the wipe member moves the wipe portion to wipe the distal end portion of the endoscope; and a conversion mechanism configured to convert the movement of the cutting member into a movement of the wipe member to interlock a cutting movement of the cutting portion with a wiping movement of the wipe portion when the cutting member moves the cutting portion between the standby position and the switching position and not to convert a movement of the cutting member into a movement of the wipe member when the cutting member moves the cutting portion between the switching position and the cutting position.
