Endoscope system with pivotable arms

摘要

An endoscopic surgery apparatus is provided, including a tubular member, a handle located on a proximal end of the tubular member, and one or more pivotable arms detachably connected to a distal end of the tubular member. The tubular member has channels along its longitudinal axis, wherein at least one of the channels is an optical channel and at least one other channel is an illumination channel. The arms have guiding channels adapted to receive surgical tools, which direct the surgical tools. The arms are interchangeable with other arms of different configurations. Also, said arms have an open and a closed position, such that when the arms are in the closed position an opening is defined allowing viewing of a surgical site via the optical channel.

1. An endoscopic surgery apparatus, comprising:
a tubular member having a plurality of channels along its longitudinal axis, the tubular member having a proximal end and a distal end; a handle located on the proximal end of the tubular member; and at least two arms pivotably connected to the distal end of the tubular member, said at least two arms each having a protruding member extending from an inner surface of the respective arm, the protruding member extending between a proximal end surface and an opposing distal end surface thereof, and a guiding channel passing through each protruding member, from the proximal end surface to the distal end surface thereof, such that the guiding channel is enclosed by the respective protruding member, wherein each guiding channel is adapted to receive an endoscopic surgical tool therethrough, an optical device, at least a portion of which is located at the distal end of the tubular member, wherein said at least two arms, when in a closed position, cover at least a portion of the distal end of the tubular member and form an obturator shape, wherein the at least two arms are shaped so that, when in the closed position, an opening is defined between the arms, the opening configured to permit viewing of a surgical site therethrough via at least the portion of the optical device located at the distal end of the tubular member.
