Claim 19:
20. A medical device comprising:
a housing;
a sheath extending along a longitudinal direction;
an end effector provided distally relative to the sheath, the end effector including a pair of grasping jaws configured to open and close;
a movable shaft provided in the sheath and connected to the end effector, the movable shaft being configured to move with respect to the sheath along the longitudinal axis so as to operate the pair of grasping jaws;
a first movable handle configured to pivot with respect to the housing about a pivot axis;
a flange connected to the movable shaft;
a moving member configured to be provided between the first movable handle and the flange, and the moving member comprising a protrusion protruding in the longitudinal direction, and
wherein:
the medical device is configured to operate in one of:
a first state in which the protrusion contacts with the first movable handle at a first position, and
a second state in which the protrusion contacts with the first movable handle at a second position,

in a direction orthogonal to the longitudinal direction, a first distance between the pivot axis and the first position is larger than a second distance between the pivot axis and the second position, and
during a movement between the first state and the second state, the moving member is configured to move in a direction intersecting the longitudinal direction.
