Abstract: Embodiments of the disclosure include an endoscope tip assembly for use on an endoscope, during procedures. The endoscope tip assembly may include a base configured to receive an endoscope tip configured to not disengage from the endoscope tip during a procedure. The endoscope tip assembly may also include a plurality of struts which is connected by a webbing, may fold flat during insertion, and may assume a balloon-like shape during withdrawal.

Abstract: An endoscopic treatment tool includes a tubular portion; a rod that protrudes from a distal end surface of the tubular portion, and has a variable protrusion amount from the distal end surface; a first connection port to which a tool for water supply or suction is connectable; a first distal end opening in a distal end surface of the rod; a first channel that extends in an axial direction of the tubular portion, and has a distal end communicating with the first distal end opening and a proximal end communicating with the first connection port; a second connection port to which the tool is connectable; a second distal end opening in the distal end surface of the tubular portion; and a second channel, and has a distal end communicating with the second distal end opening and a proximal end communicating with the second connection port.

Abstract: Provided is a medical-device hook to be attached to a medical device including a tubular portion to be inserted into a body lumen, the medical-device hook including: an inset opening allowing the tubular portion to be inset into the inset opening; and a surrounding portion around the inset opening, the surrounding portion being configured to deform elastically to come in close contact with the tubular portion inset in the inset opening such that the tubular portion is held due to frictional resistance on a closely contacted portion between the surrounding portion around the inset opening and the tubular portion.
