Abstract
Provided is an endoscope clip and an operation method for a clip. The clip includes a clip arm that is configured to be transitioned between a first, second and third configurations. The clip includes a slider to operate the clip arm to be transitioned between the configurations, and a limiter configured to restrict movement of the slider so as to restrict the transition of the clip arm from one configuration to another of the configurations.
Claims19
An endoscope clip, comprising:
- a clip arm having a first arm and a second arm, the clip arm configured to be transitioned between
- a closed configuration in which the first arm and the second arm are closed,
- a first open configuration in which the first arm and the second arm are separated from each other by a first distance larger than a distance between the first arm and the second arm in the closed configuration, and
- a second open configuration in which the first arm and the second arm are separated from each other by a second distance larger than the first distance;
- a handle;
- a slider configured to operate the clip arm to be transitioned between the closed configuration, the first open configuration, and the second open configuration by moving relative to the handle;
- and
- a limiter configured to restrict the relative movement of the slider with respect to the handle so as to restrict transition of the clip arm from the first open configuration to the second open configuration.
An endoscope clip, comprising:
- a clip arm;
- a sheath through which the clip arm is insertable;
- an operation portion configured to operate the clip arm to
- an accommodation configuration in which the clip arm is accommodated in the sheath,
- a first protrusion configuration in which the clip arm protrudes from the sheath at a first clip length from the sheath, and
- a second protrusion configuration in which the clip arm protrudes from the sheath at a second clip length from the sheath that is larger than the first clip length;
- and
- a restrictor configured to selectively restrict the clip arm from being transitioned from the first protrusion configuration to the second protrusion configuration.
An operation method for a clip, the clip including a clip arm with a first arm and a second arm, the clip arm configured to be transitioned between a closed configuration in which the first arm and the second arm are closed, a first open configuration in which the first arm and the second arm are separated from each other by a first distance larger than a distance between the first arm and the second arm in the closed configuration, and a second open configuration in which the first arm and the second arm are separated from each other by a second distance larger than the first distance, and a limiter configured to restrict transition of the clip arm from the first open configuration to the second open configuration, the operation method comprising:
- releasing restriction of the limiter;
- and
- when the restriction by the limiter is released, causing the clip arm to move from the first open configuration to the second open configuration.
