摘要：
In one aspect of the present disclosure, a device may include a shaft having a distal end, and a tip at the distal end of the shaft. The tip may include an opening defined by a surface of the tip. An instrument inserted through the shaft may extend distally out of the opening. The device also may include an elevator for engaging the instrument. The elevator may include a proximal end fixed relative to the surface of the tip, a proximal portion extending distally from the proximal end, and a distal portion extending distally from the proximal portion. A force exerted on the elevator bends the proximal portion to deflect the distal portion without bending of the distal portion.
