Electrically curvable endoscope device

Abstract

To provide an electric bending endoscope device which can always ensure good operability when using the endoscope without imposing a weight burden on the operator during the operation of the endoscope. The electric bending endoscope device includes at least: an electric bending endoscope capable of observation and treatment in a body cavity, including an elongated insertion portion inserted into the body cavity, and a device for electrically bending and driving a part of the insertion portion. A bending drive device, and an operating part that is separate from the bending drive device and electrically connected to the bending drive device; a system controller, electrically connected to the electric bending endoscope, and controls the electric bending endoscope as a whole; and An endoscope holding device, which includes a bending drive unit with a built-in bending drive device and holds a part of the electric bending endoscope, and an arm connected to and held on the bending drive unit; by attaching and detaching the bending drive unit It is freely connected and arranged on the base end side of the insertion part, and electrically connects the electric bending endoscope and the bending driving device.

Description

technical field [0001] The present invention relates to an electric bending endoscope device, and more particularly to an electric bending endoscope device including an endoscope holding device holding an electric bending endoscope which is electrically curved and driven to be set The bend on the insertion portion of an endoscope. Background technique [0002] Conventionally, the widely used endoscope is configured to observe the organs in the body cavity by inserting the elongated insertion part into the body cavity, or use the treatment instrument inserted in the treatment instrument channel of the insertion part to treat the internal organs as needed. Perform various treatments. [0003] Such a conventional endoscope is generally configured such that a bending portion capable of bending up, down, left, and right is provided on the distal end side of the insertion portion. A bending wire (wire) extending from the operation portion side is connected to the bending portion...
