Abstract
A control element for an endoscope includes a mounting base and an elastic member. The mounting base is provided with an avoidance area; the avoidance area is a hole or groove penetrating through the mounting base; the elastic member is disposed corresponding to the avoidance area; one end of the elastic member is connected to the mounting base, and the other end of the elastic member is a free end; a projection of the elastic member on a plane where the mounting base is located covers a part of the avoidance area; and the elastic member is provided with a first protrusion. The control element improves the control element corresponding to a leaf spring by redesigning the deformable portion of the elastic member. The control element increases the upper limit for the deformation amount of the elastic member while reducing resistance corresponding to unit deformation amount of the elastic member.
