Abstract

An endoscope device that enables, in insertion of an endoscope insertion section into a body cavity, the insertion to be easily and smoothly performed in a short time while allowing a user to observe the inside of the body cavity by a stable endoscope image, and that improves easiness of insertion of the insertion section into a body cavity. To achieve this, the endoscope device has an insertion section and a rotation device for rotating the insertion section about its longitudinal axis. The insertion section is provided with a forward end section having an imaging unit including an optical system and with a rotating body having a spirally shaped section on its outer peripheral surface. Further, the insertion section is flexible in its entirety and is constructed such that the imaging unit is not rotated in association with the rotation of the rotating body. The forward end section has a rotation restriction means.

Description

technical field [0001] The present invention relates to an endoscope device, and more specifically, to an endoscope device for performing endoscopic examination and diagnosis in a body cavity, particularly in the large intestine. Background technique [0002] Conventionally, endoscopes capable of performing various treatments and treatments by inserting an insertion portion of an endoscope into a body cavity such as the large intestine to observe organs in the body cavity have been widely used. [0003] Generally, an endoscope having an elongated insertion portion is provided with a curved portion on the distal end side of the insertion portion. The bending part is moved forward and backward by the operation wire connected to the bending segment body constituting the bending part, and bends, for example, in the up-down direction and in the left-right direction. The advance and retreat of the operation wire can be performed by the operator turning and operating, for example,...
