Claim 0:
1. A clip apparatus for an endoscope, comprising:
a handle body having a moving hole formed therein;
a handle slider slidably coupled to the handle body through the moving hole;
an inner sheath rotatably disposed inside the handle body and extending to an outside of the handle body;
a wire connected to the handle slider and disposed inside the inner sheath;
an outer sheath disposed to surround the inner sheath;
an outer handle coupled to the outer sheath to move the outer sheath along a longitudinal direction of the inner sheath; and
a clip coupler connected to one end of the wire,
wherein the clip coupler comprises:
a cylindrical body having a distal end surface and a proximal end surface, the distal end surface being closed;
a connection protrusion protruded from the proximal end surface of the cylindrical body and connected to the one end of the wire; and
a pair of coupling arms extending from the distal end surface of the cylindrical body and facing each other,
wherein one of the pair of coupling arms has a length greater than that of the other of the pair of coupling arms such that the one coupling arm is bent to contact the other coupling arm which is not bent,
wherein the one coupling arm has a greater flexibility than that of the other coupling
arm, further comprising a clip which is configured to be coupled to the clip coupler, wherein the clip comprises:
a pair of clip arms extending in a spreading configuration to be opened or closed;
gripping tips protruding from ends of the pair of clip arms and placed opposite to each other to be engaged with each other; and
a tightening ring configured to adjust opening and closing of the pair of clip arms,
wherein each of the pair of clip arms has protrusion portions formed on side surfaces thereof, and when the tightening ring is press-fitted into the protrusion portions, the clip is configured to be gripped,
wherein the clip apparatus is configured such that when the handle slider is slid toward the handle body, the tightening ring is press-fitted into the protrusion portions by being pushed and moved toward the protrusion portions by the inner sheath, and the one coupling arm is unfolded so as for the clip to be separated from the clip coupler.
