1. A probe device detachably coupled to a handle unit of an endoscope, the probe device comprising:
a probe deformable in response to movement of wires; and
a pair of second connectors coupled to an end of the wires and detachably coupled to the handle unit, the pair of second connectors being disposed to face each other and movable in different directions,
wherein the handle unit comprises:
a first knob and a second knob configured to be rotated independently from each other; and
a pair of first connectors configured to be coupled to the pair of second connectors,
wherein one of the pair of first connectors is in concert with an operation of the first knob and the other of the pair of first connectors is in concert with an operation of the second knob,
wherein one of the pair of first connectors and one of the pair of second connectors are configured to be engaged with each other when moving in a first direction and separated from each other when moving in a second direction,
wherein each of the pair of first connectors comprises an end tip having an insertion hole formed to extend from a distal end surface of the end tip in an axial direction of the end tip, and a cut portion formed on a side surface of the end tip, an opening of the insertion hole being defined on the distal end surface to be closed along an entire circumference of the opening and to have a shape of a slit elongated in a radial direction perpendicular to the axial direction, and
wherein each of the pair of second connectors comprises an insertion protrusion extending in the axial direction and configured to be inserted into the insertion hole, and the insertion protrusion has a head including a portion having a greater width in the radial direction than other portions of the head, such that when the insertion protrusion is inserted into the insertion hole and rotated inside the insertion hole, the head of the insertion protrusion protrudes through the cut portion and the insertion protrusion is fastened to the end tip in response to the rotation of the insertion protrusion.
