Endoscopic device insertable into a body cavity and movable in a predetermined direction, and method of moving the endoscopic device in the body cavity

摘要

In an endoscopic device insertable into a body cavity attachable elements are moved over one another to move forwardly of each other and to leave each other behind, and to move along different paths so as not to be attached to the same areas of a wall of the body cavity.

主权项

1. A device for moving equipment inside an intestine comprising:
(a) a housing, said housing elongated along a longitudinal axis; (b) at least two first attachment elements, each of the two first attachment elements:
laterally spaced from said longitudinal axis along said housing,matingly engaging a slot formed in the housing,slidable along the slot in a direction perpendicular to the longitudinalrotatable about an axis parallel to the longitudinal axis, andimmovable relative to the housing along the longitudinal axis; (c) a second attachment element located substantially coaxially with said longitudinal axis of said housing, and advanceable along a track formed along the housing;
said second attachment element configured to be displaced along said longitudinal axis: to a first state in a position distal to said first attachment elements and to a second state in a position proximal to said first attachment elements; and (d) a vacuum source coupled to each of the first attachment elements and the second attachment element, and capable of generating a vacuum level to attach the first attachment elements and the second attachment element to a wall of said intestine.
