Has the expansion possible frame the endoscope systematic manipulation tool

摘要

A tissue manipulator (50) is provided which is insertable through an endoscopic tube to enable a surgeon to manipulate tissue inside a body cavity. The endoscopic tissue manipulator includes an expandable tissue manipulating frame (80) adapted to expand transversely through a longitudinal slot (72) in a support tube (70) to provide a spatula-shaped platform which can be manipulated by rotation of the support tube about its longitudinal axis to engage and displace large body organs away from a desired surgical site in a body cavity. The frame consists of a plurality of flexible frame members or wires (81) adapted to flex laterally outward through the longitudinal slot in the support tube into a bow-shaped configuration overlapping the other frame members or wires of the spatula-shaped platform. The instrument can be provided with a single tissue manipulating frame or a pair of frames which are expandable through separate longitudinal slots in the support tube to provide a pair of spatula-shaped platforms to engage the tissue.
