Abstract: The present disclosure relates to a ligation device, an unlocking method, and a ligation instrument. The ligation device may include a clip and a limiting tube. A distal end of the clip may be used for ligation. The limiting tube may be provided with an accommodation channel, and a proximal end of the clip may be connected with the accommodation channel, and the proximal end of the clip may move into or out of the limiting tube. The clip may be provided with a locking portion, and the limiting tube may be provided with a locking position that is matched with the locking position. When the locking portion is locked with the locking position, the locking portion may be unlocked from the locking position by operating the locking portion. Alternatively, the clip may be provided with an unlocking portion that is coupled with the locking portion. The locking portion may be unlocked from the locking position by operating the unlocking portion.

Abstract: The present disclosure relates to an end effector instrument. The end effector instrument may include an end effector device. The end effector device may include a clip and a resilient portion including a connecting hole and a limiting convex. The end effector instrument may further include a delivery device including a sheath and a shaft. The sheath may include a passage that accommodates the shaft. A distal end of the shaft may include a connecting end. The sheath may include a limiting concave. The connecting end may extend into or exit from the connecting hole when the sheath is set outside the resilient portion: when the connecting end extends into the connecting hole, the resilient portion may expand outward, and the limiting convex may extend into the limiting concave; when the connecting end exits from the connecting hole, the resilient portion may rebound, and the limiting convex may exit from the limiting concave.
