Problems solved by technology

However, in electric endoscopes, the operator cannot unintentionally change various bending operations according to the use state of the endoscope, and always responds to fixed operation inputs only by driving a fixed bending part, for example, for Fixed joystick tilt angle always only responds with a fixed bend speed
Therefore, it is not easy to use an electric endoscope to perform treatment as effectively as manual control in a manually driven endoscope, and the operation of the electric endoscope requires skill.
In addition, when using a treatment tool to perform various treatments, if the operator misoperates the operation input unit, unexpected large bending drive may be performed.

Abstract

A medical instrument with an active bending section includes: an insertion section having a treatment instrument projection port and an active bending section at a position on the insertion section's proximal end portion side of the treatment instrument projection port; a joystick by which an operation of the active bending section is inputted; a driving section for driving the active bending section; and a control section for controlling the joystick and the driving section, and the control section having an active bending section which performs a control in one control mode selected from a plurality of different control modes.

Description

technical field [0001] The present invention relates to a medical device, and in particular, to a medical device having a treatment tool protruding from a treatment tool protruding opening at a front end thereof and inserted into a subject, and an active bending part. Background technique [0002] The endoscope observes internal organs and the like in the body cavity by inserting an elongated insertion portion into the body cavity, and performs various therapeutic treatments using a treatment tool inserted (inserted) through the treatment tool channel. Also, in the industrial field, an endoscope can observe or inspect internal damage and corrosion of boilers, turbines, engines, or chemical equipment, etc., by inserting an elongated insertion portion inside. [0003] In this type of endoscope, a freely bendable bending portion is continuously provided at the distal end portion of the elongated insertion portion. In order to bend the bending part of the endoscope, the so-call...
