Abstract
A medical instrument, 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.
Claims15
A medical instrument, comprising:
- an elongated insertion section to be inserted into a subject, which is provided with a treatment instrument insertion port at a proximal end portion of the insertion section through which a treatment instrument, which is a separate body from the insertion section, is inserted, a treatment instrument projection port at a distal end portion of the insertion section through which the treatment instrument is projected out, and an active bending section at a position on the proximal end portion side of the treatment instrument projection port at the distal end portion;
- an input section for inputting an operation of the active bending section;
- a driving section for driving the active bending section based on an operation signal from the input section;
- a control section for controlling the driving section and the input section in one control mode selected from a plurality of different control modes;
- and
- a projection detection section, disposed at the distal end portion of the insertion section, for detecting the presence of a projection of the treatment instrument from the treatment instrument projection port, wherein
- the control section selects the one control mode based on the information from the projection detection section;
- the plurality of control modes are different from each other in driving speeds of the active bending section, and
- based on the information from the projection detection section, when a projection of the treatment instrument from the treatment instrument projection port is detected, the control section selects a control mode for a lower driving speed of the active bending section of the insertion section than a driving speed when the treatment instrument is not projecting from the treatment instrument projection port.
