Endoscopic apparatus having a clip device

摘要

A hemostatic clip delivery system cooperable with an elevator of an endoscope and a method of treating a target with the system are disclosed. The system comprises a delivery apparatus comprising an operating wire, an outer sheath and a handle. The operating wire is cooperable with the elevator of the endoscope and slidably disposed within the outer sheath. The system further comprises a hemostatic clip cooperable with the delivery apparatus. The clip comprises a first retainer, a plurality of arms extending distally from the first retainer, and a sliding ring disposed about the plurality of arms. The arms are shaped so that the arms tend to be spaced apart from each other. The sliding ring is configured to close the arms together as the elevator engages and moves the sliding ring toward the arms by retraction of the operating wire.

1. A hemostatic clip delivery system cooperable with an endoscope having an elevator with a slot formed thereon, the system comprising:
a delivery apparatus comprising an operating wire, an outer sheath and a handle, the operating wire being cooperable with the elevator of the endoscope and slidably disposed within the outer sheath; and a hemostatic clip cooperable with the delivery apparatus, the clip comprising a first retainer, a plurality of arms extending distally from the first retainer, and a sliding ring disposed about the plurality of arms, the arms being formed of a resilient material and shaped so that the arms tend to be spaced apart from each other, wherein the sliding ring is connected to the operating wire, and wherein the outer sheath engages the elevator as the outer sheath is moved in a distal direction, the elevator is positioned next to the sliding ring whereafter the sliding ring is exposed to the slot of the elevator when the outer sheath is pulled in a proximal direction, and the sliding ring engages the elevator when the operating wire is retracted such that the elevator moves the sliding ring toward the arms to close the arms together; wherein the outer sheath is separate from the elevator and moveable relative to the elevator.
