Problems solved by technology

Therefore, in the conventional electric bending endoscope, when the operation unit is changed in order to use the bending instruction unit corresponding to the case and the habit of the surgeon, each time the operation unit is changed, it is necessary, for example, to perform the above-mentioned adjustment on the system controller side. There is a problem that the operation of changing the operation part is complicated due to the correction work of correcting the difference in the output signal of the operation part
[0014] In the prior art described in the Japanese Patent Application Publication No. 2003-245246 and the Japanese Patent Application Publication No. 8-224206, regarding electric bending endoscope Mirror, there is no description of the technology related to the operation of correcting the difference in the output signal of the above-mentioned operation unit when the operation unit is changed, and the technology of simplifying the operation of changing the operation unit

Abstract

An electrically bent endoscope device (1) has an endoscope (2) having a drive unit (13), a control unit (3), and an operation section (9) having a bend instruction section (9A). The operation section (9) has a joystick (9A) attached to the operation section (9) and functioning as the bend instruction section (9A). The operation section (9) also has a correction algorithm operation section (40) for creating an operation signal for the bend instruction section. The operation signal is created by converting an output range of an instruction signal of the joystick (9A) in such a way that the instruction signal coincides with a predetermined output range of an instruction signal of the bend instruction section, where the instruction signal is an operation signal that the operation section (9) outputs.

Description

technical field [0001] The present invention relates to an electric bending endoscope device having an electric bending endoscope. The electric bending endoscope has an operation part which can be mounted with a bending instruction part and outputs an operation signal of the bending instruction part. The bending is in a state corresponding to the operation signal of the bending instruction unit. Background technique [0002] Conventionally, endoscopes have been widely used. By inserting the elongated insertion portion of the endoscope into the body cavity, the surgeon can observe the internal organs of the body cavity and perform various treatments as necessary using the treatment instrument inserted in the treatment instrument channel. In addition, in the industrial field, workers can observe or inspect internal damage, corrosion, etc. of boilers, turbines, engines, chemical equipment, etc. by inserting the elongated insertion portion of the endoscope. [0003] In such an...
