Abstract

The present invention provides a power driven bending endoscope with detachable insertion portion. An electrically bendable endoscope (2) of a type where an insertion section is removable is constructed such that an insertion section body (3) and a motor unit (4) are detachable from each other, the insertion section body (3)having bendable section (3B), the motor unit (4) having an electric motor (23) for bending and driving the bendable section (3B) and a potentiometer (26) for detecting the state of bending of the bendable section (3B).

Description

technical field [0001] The present invention relates to a detachable insertion portion electric bending endoscope including an insertion portion main body having a bending portion and a bending drive unit for electrically bending the bending portion. Background technique [0002] Endoscopy has been used extensively throughout the ages. In an endoscope, by inserting an insertion portion into a body cavity, it is possible to observe the inside of the body cavity. In addition, various treatments and treatments can be performed by inserting a treatment tool into the treatment tool insertion channel provided in the insertion part as needed. [0003] Generally, in an endoscope having an elongated insertion portion, a curved portion is provided on the distal end side of the insertion portion. The bending portion is formed by connecting a plurality of bending pieces freely rotatable. The operation wire is connected to the bending piece constituting the bending portion. In additi...
